Three-Body

The investigation uncovers Shen Yufei's death by suicide. At an offline party for the Three-Body game, Pan Han reveals the reality of the Three-Body world and discusses their search for a new home. Wang Miao supports Pan Han and informs Shi Qiang about the event, exposing the Three-Body organization ETO. Pan Han shows Mu Xing evidence of global solar station shutdowns.

Ye Wenjie pays her homage to Shen Yufei and learns about the Adventists. Wang Miao and Shi Qiang suspect divisions within the ETO. Wang Miao continues playing the game while the game server's location is discovered. Pan Han calmly shuts down the server.In the game, Wang Miao discovers the Three-body's departure to the solar system.Mu Xing and Pan Han plan to meet, but Shi Qiang intervenes.

Clues link Chen Xue to ETO and the K1303 train killing. Wang Miao learns of the ETO gathering, and the Battle Command Center plans an arrest operation. Chen Xue reveals restored files to Ye Wenjie, implying Yang Dong knew her ETO identity. At the conference, accusations fly, Pan Han denounces Shen Yu Fei, and Ye Wenjie accuses the Adventists.

Ye Wenjie, who conducted research at the Red Coast Base, comes up with a bold exploration plan: use the sun as an amplifier to transmit signals into the universe. Despite Lei Zhicheng’s opposition, she implements this experiment during a machine maintenance. Later, with the world in war and nuclear weapons threats, she believes that human’s madness had reached its pinnacle.

On Radar Peak, Ye Wenjie replied to Trisolarans, which determined the fate of humanity. She tells Wang Miao that the nano-materials he has done research on can be used to build the space elevator, which will threaten the advent of the Lord. At this time, Shi Qiang leads the special operations team to rush into the meeting room. Someone confesses to murder, while another loses their life.

Lei Zhicheng wanted to monopolize the message that Ye Wenjie received from Trisolarans. Ye faked a fault and led Lei to repair it, but her husband Yang Weining appeared and insisted on helping Lei.

Ye Wenjie met Mike Evans in the northwest China. He planted trees there to save an endangered bird. Three years later, almost all the trees of Evans were cut down by the villagers. He confirmed that human beings were hopeless. Inspired by Ye’s findings at the Base, Evans built a huge ship named “the Judgment Day”.Ye says the Adventists’ intercepted information of the Lord is stored on the ship.

According to Ye Wenjie, the Trisolaris launched two protons into the solar system six years ago to lock the progress of human science. That means, during the four and a half centuries until the arrival of the Trisolaran Fleet, humanity cannot make any important scientific developments.Ding Yi and Wang Miao want to figure out what the two protons will do, but fail to find an answer.

The Battle Command Center finds a 28-GB hard drive, which contains a Three-Body game client, through which Wang Miao and Shi Qiang enter the game again. In the game, monitor No.1379 says he received the letter from the Red Coast Base. He sent the warning message to protect Earth. Sanctioned for betrayal, however, monitor No.1379 has to live until the Earth completely loses hope.

The Trisolaran Chief announces that in four and a half million Trisolaran hours, their fleet will reach the solar system. To curb Earth’s civilization from leaping ahead, the Trisolaran develop the plans code-named Coloring and Miracle, and Project Sophon. They transformed two protons into super intelligent computers and launched them to Earth.
