-Ye Wenjie's father, Ye Zhetai, died after being criticized. Ye Wenjie watched helplessly in the audience as several "Red Guards" tortured his father to death. During this period, his mother Shaolin's inaction also increased Ye Wenjie's disappointment in this society.

-China established the Red Coast Base to explore extraterrestrial civilizations.

-Ye Wenjie was assigned to work in the Inner Mongolia Production and Construction Corps in Daxinganling. Due to the frame-up made against her by reporter Bai Mulin, she was considered to have incorrect ideas and was suspected of being reactionary, and was imprisoned. - Desperate Ye Wenjie was unexpectedly selected by Yang Weining, the chief engineer of Hong'an Base, because of her ability in astrophysics, and was transferred to work at Hong'an Base.

- Half a year after Ye Wenjie entered the Hong'an Base, he speculated on a foreign paper that the sun has the ability to amplify radio signals. Ye Wenjie thought of using the sun's radio wave amplification function to emit radio waves into the universe through the sun. However, this behavior was strictly prohibited by Lei Zhicheng, the political commissar of the base due to its political particularity (at this time, he was at the peak of all political illustrations. In ridiculous times, the act of sending extremely strong radio waves towards the red sun could easily be understood as having reactionary political implications).

-Ye Wenjie found an opportunity to secretly send radio waves to the sun. For the first time, information about earth civilization was truly sent to every corner of the universe.

-Of course, Ye Wenjie and Yang Weining, who often work together, started a family.

-The Trisolaran civilization 4 light years away from the earth received a message from the earth civilization. Because a certain monitor in the Trisolaran world (a post set up by the Trisolaran civilization to monitor information in the universe) did not want to destroy the earth's civilization, so he sent a warning message to the general direction where the message was received - warning the earth's civilization not to do it again Reply, because that will make the Trisolaran civilization understand the location of the earth, which will lead to the invasion and occupation of the earth.

-Ye Wenjie received a warning message from the Trisolaran civilization. Ye Wenjie, who was extremely desperate for her own society, decisively responded to the Trisolaran civilization with a message, asking the Trisolaran civilization to come and help transform the earth's civilization. -Ye Wenjie learned that she was pregnant. -Eight hours after Ye Wenjie sent the message, it was learned that Lei Zhicheng, the political commissar of the base, had also received information about the Trisolaris civilization in the background, and that Lei Zhicheng was preparing to report this discovery to the outside world. -In order to prevent the Trisolaran civilization from affecting the transformation of earth civilization, Ye Wenjie believed that this secret could only be known to herself, so Ye Wenjie designed and killed the base political commissar Lei Zhicheng, and her husband Yang Weining was also killed in the "accident" she caused.

-Ye Wenjie’s daughter Yang Dong was born.

-Evans came to China to plant trees out of his desire to protect the earth's environment, and wanted to build a home for birds that would not be destroyed. -The first Trisolaran fleet set sail from Trisolaran World and headed for the Earth.

-The cases of Ye Wenjie and Ye Zhetai were both vindicated -Ye Wenjie received a letter from Tsinghua University saying that she could go back and continue teaching. In order to have an income to support her daughter, she left the Hong'an base and returned to Beijing, where she became a professor of astrophysics in the Department of Physics at Tsinghua University. -In the second half of the year, Ye Wenjie took on a project and was asked to design a large-scale radio astronomy observation base. She met Evans for the first time while exploring the site and learned why Evans was there. -The Trisolaran civilization received the message from Ye Wenjie's reply and began to build a giant accelerator and launch the sophon project, in order to lock down the development of earth civilization in basic science.

-Ye Wenjie met Evans again and saw that the woods that Evans had planted for five years were being cut down by local officials. Evans despaired of the world. Ye Wenjie thought that Evans had the same views on the world as she did, so she told Evans about the Trisolaran civilization. -Evans used the property left behind by his family to buy the cruise ship "Judgment" and built the Second Red Bank Base on the "Judgment", sending a large amount of information about earth civilization to the Trisolaran civilization, hoping that the Trisolaran civilization Civilizations can understand earth civilization and thus better deal with earth civilization.

-The Trisolaran civilization built a giant accelerator, and the sophon project officially entered the operational stage.

-Ye Wenjie was invited by Evans to go to the "Judgment". Evans announced Ye Wenjie as the supreme commander of the Earth Trisolaran Movement on the "Judgment". This day is recognized as the birth day of the Earth Trisolaran Movement.

-The Trisolaran civilization successfully expanded a proton into two dimensions and etched the circuit, transforming the two-dimensionally expanded proton into a supercomputer "sophon"

-The Trisolaran civilization completed the circuit etching of two-dimensional expanded protons and built the first supercomputer "Sophon".

-The Trisolaran civilization built the second "sophon".

-The Trisolaran civilization built the third "sophon"

-The Trisolaran civilization built the fourth "sophon", two of which were sent to the earth. -Ye Wenjie retired from Tsinghua University.

- UNESCO designated this year as the World Year of Physics. In the same year, the "Science Frontiers" society was born, and ETO (Earth Trisolaran Organization) selected candidates from the society who were suitable to join the organization.

-The two sophons sent by the Trisolaran civilization arrived on the earth. From then on, the Trisolaran civilization can monitor everything on the earth in real time. At the same time, they use the microscopic particle physics properties of sophons to hinder the development of basic science of the earth civilization.

- Yang Dong learned her mother Ye Wenjie’s secret about the three-body world. She lost hope in this world and chose to commit suicide. -Luo Ji met Ye Wenjie by chance when he went to pay homage to Yang Dong's grave, and learned from Ye Wenjie his original ideas about the axioms of universal civilization. The Trisolaran civilization learned about this accidental meeting through Sophon. They were afraid that the earth civilization would truly understand the axioms of cosmic civilization-the laws of the dark forest, which would pose a threat to the Trisolaran world. Therefore, the Trisolaran civilization ordered ETO to eliminate Luo. Editing instructions. -The "Science Frontier" society was destroyed by the military, and its leader Ye Wenjie was sentenced to death for committing crimes against humanity. After the execution, her tombstone was placed next to her daughter Yang Dong. -The "Judgment" where Evans was located was destroyed by military operations. Evans and a group of ETO members on the "Judgment" died in this operation. -The world has entered a state of war and officially entered the era of crisis.

-Cheng Xingang finished his studies and started working, joining the research team developing engines for the new generation Long March rocket. Cheng Xin later joined PIA (Planetary Defense Council Strategic Intelligence Agency) and proposed a ladder plan, preparing to "launch" an Earthling to the Trisolaran civilization and penetrate into the Trisolaran civilization. Because the acceleration method of the aircraft is very similar to climbing a ladder, it is named the ladder plan. -PIA begins studying feasibility options for the ladder plan.

-The United Nations launched the Star Project and began selling observed stars in the universe to the public. -Trisolaris Civilization once again issued instructions to the remaining members of the ETO organization to eliminate Luo Ji. -The Earth Space Force is established. -Luo Ji was assassinated by ETO, but Luo Ji accidentally avoided it. -The PDC (Planetary Defense Council) learned about the Trisolaran civilization's fear of Luo Ji from ETO members, so it arranged for Luo Ji to attend the 19th meeting of the PDC and announced that Luo Ji was elected as the Wallfacer. -On the day after becoming a Wallfacer, Luo Ji suffered a second assassination from ETO. This assassination injured Luo Ji but did not threaten his life. -After two years of feasibility study on the Ladder Plan, PIA finally found that the Ladder Plan was only enough to launch a human brain into space. -The Ladder Plan is fully launched, and PIA begins to look for candidates to implement the Ladder Plan. -Luo Ji used the resources that the Wallfacer could mobilize to move into his own "Xanadu", found the lover of his dreams, and then began his life of isolation from the world. -The Hubble 2 Space Telescope discovered traces of the Trisolaran fleet passing through interstellar dust clouds, further confirming the fact of the Trisolaran invasion for Earth civilization.

-Euthanasia law passed in China. -The Stars Project is officially launched on the Chinese website. After learning about this, Yun Tianming decided to use his wealth to give his crush Cheng Xin a star. -Cheng Xin received a star (DX3906) bought for her anonymously by her college classmate Yun Tianming. -Twenty-eight-year-old Yun Tianming decided to euthanasia after giving Cheng Xin stars. -When Cheng Xin was looking for candidates for the Ladder Plan, she thought of her terminally ill college classmate Yun Tianming. Cheng Xin found Yun Tianming and asked him about his wishes. Yun Tianming decided to participate in the selection of mission executors of the Ladder Plan.

-Yun Tianming became a candidate for the Ladder Plan and was tested. He passed all kinds of tests perfectly and was elected as the mission executor of the Ladder Plan. -As Yun Tianming's condition gradually worsened, he immediately underwent brain resection surgery.

-Earth civilization began to build space elevators - "elevators" that go directly from the ground to space. -The Ladder Plan has entered the launch stage. Yun Tianming's brain, which was taken out two years ago, is loaded into an aircraft and launched into space. -PIA needs someone who understands the Ladder Plan to go to the future. Cheng Xin, who proposed the Ladder Plan and met Yun Tianming, became the best candidate. Cheng Xin began to hibernate and prepared to wake up when the ladder plan came to fruition.

- Luo Ji's wife and children were taken away by the United Nations, and the United Nations used this to ask Luo Ji to do what he should do as a Wallfacer. - Luo Ji began to think about and put forward conjectures about the laws of the dark forest, and began to verify them. -After the Trisolaran civilization monitored Luo Ji's behavior, it once again issued an order to ETO to eliminate Luo Ji. -Luo Ji was attacked by ETO's genetic weapon and forced into hibernation, preparing to be sent to the future for treatment. -PDC sent the coordinate information of star 187J3X1 to the universe in accordance with Luo Ji's request to verify Luo Ji's conjecture about his own theory. -Feeling fear, the Trisolaran civilization launched ten probes to the earth.

-The Hubble 2 Space Telescope discovered special traces left by ten detectors launched by the Trisolaran fleet as they passed through dust clouds. -Earth's three space elevators are built. -Due to the gradually spreading defeatist sentiment in the existing space force, a group of political task forces used to reinforce the future began to hibernate. Their purpose was to convey a firm belief in victory to the future.

-The transformation of the world economy caused by preparation for war has made the whole world hungry and everyone is in danger.

-Environmental pollution, greenhouse effect, climate anomaly, desertification...

-The "Big Low" begins.

-The end of the "Great Trough" that lasted for half a century, during which the world's population dropped from 8.3 billion to 3.5 billion. -The United Nations declared that it was out of a state of war, and countries around the world began to focus on improving people's living standards.

-After more than twenty years of adjustment, people have returned to the living standards of the Golden Age.

-The technology of Earth's civilization has advanced rapidly. Technical problems that had not been solved for a long time have been overcome one by one, and people's living standards have risen rapidly.

-The world once again declared a state of war. -Earth begins to build a space fleet.

-The 187J3X1 star was destroyed by a dark forest attack. At this time, 146 years have passed since the PDC launched the coordinates of the 187J3X1 star into the universe.

-The remaining members of the ETO organization were completely eliminated. -The space fleet is independent and no longer affiliated with any country on Earth. The original Planetary Defense Council was renamed the Joint Solar System Fleet Conference.

-The space telescope on the earth observed the destruction of the star 187J3X1, but because the public was immersed in a happy life at this time, they believed that the space fleet owned by the earth was enough to easily defeat the Trisolaran fleet, so no one paid attention to this The star has been destroyed.

-Luo Ji wakes up from hibernation. The Solar System Fleet Joint Meeting announced the suspension of the "Wall Facer Project", and Luo Ji was relieved of his status as a "Wall Facer". -Zhang Beihai, who joined the task force to reinforce the future political work two centuries ago, woke up from hibernation and became the executive captain of the "Natural Selection". -Zhang Beihai, who believed that the United Earth Fleet would definitely lose in the war, operated the "Natural Selection" to escape from the solar system. "Blue Space" and three other battleships set out to pursue the fleeing "Natural Selection". -A three-body probe "Water Drop" arrived in the solar system ahead of schedule. The United Earth Fleet, composed of two thousand space battleships, was defeated in front of the small water drop. The United Earth Fleet was destroyed by the "Water Drop". - After learning the news of the destruction of the United Earth Fleet, five battleships, including the four pursuit battleships and the "Natural Selection", expressed their greatest respect to Zhang Beihai. Zhang Beihai announced the establishment of "Starship Earth", with all personnel on the five battleships as members. - Since the fuel it carried was insufficient for interstellar navigation, the "Blue Space" wiped out everyone in the other four battleships and took away the fuel and supplies reserved on the other ships. -Shortly thereafter, Earth civilization discovered the fact that the star 187J3X1 was destroyed a year ago. The "Wall Facer Project" was restarted, and Luo Ji was appointed as the only "Wall Facer." - Luo Ji began to participate in leading the construction of the "Snow Project" (using stellar hydrogen bombs and Neptune's oil film material to create space dust clouds to show traces of the Trisolar probe's "water droplets" when they pass through).

-Luo Ji used the nuclear bombs deployed during the construction of the "Snow Project" to establish a dark forest deterrent.

-Luo Ji handed over the detonation switch of the solar nuclear bomb chain to the United Nations and the Solar System Fleet. After learning about the Law of the Dark Forest, people analyzed and found that the detonation switch that deterred the entire Trisolaran civilization could not be controlled by the public, so Luo Ji took the switch back only eighteen hours later and continued to maintain the Dark Forest's deterrent . -The Earth civilization established the World Academy of Sciences and began to receive knowledge from the Trisolaran civilization.

-The gravitational wave antenna was completed, and the switch of the gravitational wave emission system was handed over to Luo Ji. As long as Luo Ji pressed the button, the galaxy coordinates of the Trisolaran civilization would be transmitted to the entire universe.

-Luo Ji entered Control Station Zero of the Gravitational Wave Cosmic Broadcasting System to maintain the dark forest as a deterrent. From then on, he became isolated from the world and became a "sword bearer", maintaining the balance of the two worlds single-handedly.

-Trisolaris began to send their cultural and artistic works to the earth.

-The Bronze Age goes on trial. The "Gravity", equipped with a gravitational wave launch system, and two water droplet formations set sail to pursue the "Blue Space".

-The Trisolaran First Fleet intercepted the aircraft carrying Yun Tianming's brain. -Based on the genetic information carried in Yun Tianming's brain, the Trisolarans cloned Yun Tianming's body and put Yun Tianming's brain into their cloned body. -The Trisolarans provided a piece of land for Yun Tianming as a living place, and began to observe and record Yun Tianming's various living habits and behavior patterns.

-Yun Tianming cultivates, lives and learns the language, history and culture of the Trisolaran civilization in the Trisolaran First Fleet.

-Due to the growing prejudice of Earth civilization against Luo Ji, people began to put Luo Ji on trial. They believed that Luo Ji at this time was more like a dictator and that the fate of two civilizations should not be controlled by such a person, so people decided to replace the "sword holder" Luo Ji. -Cheng Xin’s DX3906 star was discovered to have two planets by doctoral student Ai AA. So Cheng Xin was awakened from hibernation, and the United Nations asked to buy back the DX3906 star from Cheng Xin. -Cheng Xin transferred the rights to use the two planets carried by the DX3906 star to the United Nations, and Ai AA used the money obtained to establish the Star Ring Company. - Thomas Wade, the first director of PIA, believed that Cheng Xin would definitely be elected if she ran for "Sword Bearer", but Wade also believed that Cheng Xin did not have the ability to serve as "Sword Bearer" and could not maintain the dark forest deterrence, so He chose to assassinate Cheng Xin, but the assassination failed and Vader was sentenced to 30 years in prison. -Cheng Xin ran for "Sword Bearer". -The two water droplets traveling with the "Gravity" entered the sophon blind zone and cut off real-time communication with the earth.

- "Gravity" approaches "Blue Space". At this time, the two ships are 1.5 light years away from the earth, so what happened between the two ships will not be known to earth civilization until 1.5 years later. -May--Cheng Xin was elected as the second "Sword Bearer" through popular vote. -November 28, 16:00-16:17--The new and old sword holders completed the handover. -November 28, 16:17-16:27--The moment the sword holder completed the handover, the water droplets hidden in the solar system immediately rushed towards the earth. Then the water droplets destroyed the three gravitational wave launchers on the earth, suppressing the sun's Radio wave amplification function. During this process, Cheng Xin never pressed the gravitational wave emission switch, and the dark forest deterrent failed. -November 28, 16:17-16:27 --Two water droplets following the "Gravity" suddenly attacked the "Blue Space" and the "Gravity" respectively. --Members aboard the "Blue Space" used four-dimensional space fragments to destroy two water droplets. --After guessing that the reason for the water droplet attack was due to the failure of the dark forest deterrent, members on the two ships voted to activate the gravitational wave emission system on the "Gravity", and the coordinates of the Trisolaran Galaxy were broadcast into the universe.

-January 4th--The Earth discovered through the Trisolaran Fleet through the traces of dust clouds that the second fleet of the Trisolaran Civilization has set off for the Earth, and through analysis it was found that the second fleet of the Trisolaran Fleet can sail at the speed of light and will sail at the speed of light on 4 Arrive in the solar system years later. -January 26th--Sophon announced that Australia on Earth and one-third of the territory of Mars will be reserved for the residence of Earth civilization, and humans need to complete the immigration action within one year. -January 31st--Cheng Xin and Ai AA followed the first batch of immigrants to Australia.

-January 23 --Three days before the deadline, the Great Immigration was completed. --Three-body civilization announced that the 4.2 billion people living in Australia must spend three months in isolation in Australia, during which there will be no food supply. --Cheng Xin suffered retinal detachment, necrosis, and blindness due to the extremely strong mental shock she suffered. She also fell into a mild depression. -January 29 --The Trisolaran world learned that the "Gravity" had launched a gravitational wave broadcast. The Trisolaran civilization, which believed that the solar system was no longer safe, controlled the Trisolaran fleet to steer away from the solar system, and the water droplets were also evacuated from the earth at the same time. --Earth civilization began with the evacuation of Australia.

-February--Cheng Xin set off to return to her motherland and began hibernating for a short period of time, waiting for the retina that could heal her eyes to be manufactured. -June--The evacuation is completed.

-The Trisolaran world was destroyed by the Dark Forest, only 4 years after the "Gravity" launched the gravitational wave broadcast.

-Yun Tianming carefully compiled a series of fairy tales in the Trisolaran First Fleet, and hid the information he wanted to tell earth civilization in three of them.

-Cheng Xin woke up from short-term hibernation, completed a retinal transplant and restored her vision. -Earth civilization observed the destruction of the Trisolaran world, once again verifying the existence of the law of the dark forest. -Three days after observing the destruction of the Trisolaran world, the sophon robot controlled by the Trisolaran civilization invited Cheng Xin and Luo Ji to have tea. Luo Ji learned from the conversation with the Trisolaran civilization that it was possible to release a message to the universe to avoid darkness. Forest Strike Safety Statement. -The sophon robot invited Cheng Xin and Luo Ji to have tea, bid farewell to humans, and informed that all sophons would leave the earth. It also informed Cheng Xin that Yun Tianming wanted to see her. -Cheng Xin met with Yun Tianming and learned about the three fairy tales compiled by Yun Tianming for earth civilization. Afterwards, Yun Tianming and Cheng Xin agreed to meet in the DX3906 star system. -The Intelligence Interpretation Committee (IDC) was established and began to interpret Yun Tianming's fairy tale.

- Combined with the information brought by the interpretation of Yun Tianming's fairy tale, earth civilization envisioned three ways to deal with the attack in the dark forest: the bunker plan, the black domain plan, and the light speed spacecraft plan. -The Ringer-Fitzroy Observatory observed the traces left by the Trisolaran civilization's curvature-driven spacecraft (lightspeed spacecraft) when it sailed, causing Fleet International and the United Nations to quickly and comprehensively ban the research on curvature-driven spacecraft. - Vader was released from prison and asked Cheng Xin to hand over the Halo Company to him so that he could secretly develop a light speed spacecraft. -After discussing with Ai AA, Cheng Xin decided to hand over the Star Ring Company to Vader, but retained the right to decide on important events. Afterwards, Cheng Xin and Ai AA entered hibernation.

-The Sun-Ring Accelerator is put into operation. - Vader began to use the circumsolar accelerator to produce antimatter bullets, preparing to use them at critical moments to threaten those who hinder the development of light-speed spacecraft.

- Luo Ji serves as the chairman of the Earth Civilization Museum Construction Committee and presides over the construction of the "Earth Civilization Museum".

-At this time, the federal government is hindering the Halo Group's further testing of curvature drive technology, and Vader is preparing to use a large number of anti-matter bullets to threaten the federal government. Cheng Xin woke up from hibernation and was taken to Star Ring City. Vader showed Cheng Xin the curvature drive technology that was initially successfully developed, and explained to her the situation at this time, which required Cheng Xin to decide whether to resist the federal government. -After Cheng Xin learned about the damage that antimatter bullets could cause, she resolutely asked the reactionary army to stop resisting. - Vader fulfilled his promise to Cheng Xin, implemented her decision, surrendered to the federal city and handed over all anti-matter bullets. - Thomas Vader was sentenced to death for crimes against humanity, war crimes, and violations of laws prohibiting warp drive technology. -Star Ring Group’s research on curvature drive technology has stalled. -Ai AA wakes up from hibernation and returns to earth with Cheng Xin for a walk. Afterwards, Cheng Xin and Ai AA hibernated again in Asia Space City No. 1, preparing to wake up after the attack from the dark forest.

-Research on space curvature drive technology is resumed at the Mercury base.

-Three sets of warp engines were secretly manufactured and conducted two trials. Engine No. 1 for the first trial will return in three years, and engines No. 2 and No. 3 for the second trial are expected to return ten years later.

-The No. 1 warp engine returned from the first trial voyage was installed on the "Halo". -The solar system was attacked by the dark forest of advanced civilization, and the solar system early warning system discovered the "two-way foil" launched by the advanced civilization.

-The attack from the dark forest arrives, and Cheng Xin and Ai AA wake up from hibernation. -Cheng Xin and Ai AA took the Halo to the Earth Civilization Museum on Pluto, and learned from Luo Ji that the Halo could fly at the speed of light. -Luo Ji lost his life in the Earth Civilization Museum on Pluto. -The entire solar system was "two-dimensional", and Cheng Xin and Ai AA escaped from the solar system as the only survivors. -Cheng Xin and Ai AA took the curvature-driven spacecraft "Halo" to the star DX3906

-Cheng Xin and Ai AA arrived in the DX3906 star system and landed on the Blue Star. They met Guan Yifan, a researcher on board the "Gravity". - In order to confirm whether Yun Tianming had arrived, Cheng Xin and Guan Yifan took the "Hunter" to another planet in the star DX3906 to check for traces of the landing of other spacecraft. -Ai AA on the Blue Star notified Cheng Xin through the "Halo" that Yun Tianming had landed on the Blue Star. After learning the news, Cheng Xin and Guan Yifan immediately set off to return to Blue Star. -Cheng Xin and Guan Yifan strayed into the dark territory on their way to Blue Star on the "Hunter". In the black domain, the computer functions on the "Hunter" were unable to function normally, and the spacecraft fell into a flameout state. Guan Yifan set out to activate the neuron computer on the spacecraft, but this process took twelve days.

-The "Hunter" that mistakenly entered the black domain was restarted. At this time, the "Hunter" had been sailing around the Blue Star at low light speed in the black domain for a full sixteen days. The universe was already changing. - Guan Yifan piloted the "Hunter" to land on Blue Star. Cheng Xin and Guan Yifan discovered the small universe given to them by Yun Tianming and entered it. -The small universe is activated, and the timeline of universe 647 begins. -Cheng Xin and Guan Yifan cultivated, lived and learned the language, history and culture of the Trisolaran civilization in the small universe.

-Cheng Xin and Guan Yifan, who have lived in the small universe for a year, received the supermodel broadcast from the big universe. -Cheng Xin and Guan Yifan responded to the return movement of the macrocosm and came out of the microcosm and returned to the macrocosm.
