Episode 6

As global panic spreads, the news that the Trisolarans are heading to the earth is like an inescapable disaster.People began to fall into despair, and riots and suicides occurred frequently.Various sects emerged, some worshiped the Three Body as the savior, while others began to seek unity and vowed to protect the earth and mankind.Ye Wenjie fell into silence after hearing the Trisolarans calling humans “bug”.Cheng Jian was confused by this. She didn't understand why Vera Ye had to die, and what qualifications Ye Wenjie had to decide the life and death of others.Ye Wenjie mentioned the slogan "Destroy the old world and create a new world" on the posters during the Cultural Revolution. She said that she would use the power of Trisolaran people to achieve this goal.

In Cheng Jian's view, Ye Wenjie was just looking for rational excuses for his actions and decisions.She believes that Ye Wenjie has never really considered the possible consequences of her decisions, and no one has given her the qualifications and power to make decisions for others.Cheng Jian felt that Ye Wenjie only cared about her own interests and ideas, and her behavior was actually a kind of betrayal.

At the same time, Vader began to organize scholars to fight back against the Trisolarans.He knows that the Trisolarans have sophons that can monitor all information on the earth, but he believes that existing scientific and technological research cannot stagnate.Vader plans to launch a probe to intercept the Trisolaran fleet and learn the Trisolaran way of doing things.His goal is to keep the two sophons too busy with research activities on Earth to fully monitor humanity's secret plans.

In order to achieve this goal, Vader needs Cheng Jian to use existing technology to make the detector reach at least 1“ of the speed of light.Cheng Jian proposed to scholars the plan of using nuclear weapons to accelerate detectors, but the scholars had reservations about this.They believe that four hundred years is still plenty of time and there is no need to rush for detection.However, Vader insisted on carrying out the plan immediately.

At this time, the Stars Project attracted the attention and investment of the richest people.These wealthy people hope to compete for ownership of the stars in the Milky Way by investing in the Star Project.Oji is disgusted by this kind of money being spent on nothing. She believes that these funds should be used to help those in need.Raj volunteered to join the space fleet and was sent to the moon to build a probe.

At Will's home, the Oxford ”4% group gathered to discuss the Trisolaran problem.Oji was dissatisfied with Cheng Jian's behavior in helping Wade, and accused Raj of being too cold-blooded during the Guzheng operation in Panama.Cheng Jian tried to explain the truth and plans of the Trisolarans, but Aoji was unwilling to listen.She believed that handing the world's resources to a select group of scientists would lead to tragedies, such as the creation of the atomic bomb.

The next day, Will said goodbye to Cheng Jian, while Sol and Oji encouraged Will to express his feelings to Cheng Jian.Although Cheng Jian already has a boyfriend, they think Will should not have any regrets.So Will boarded the train to London, hoping to find Cheng Jian.

In London, Cheng Jian and Raj argued over the loss of more than a thousand lives in Operation Guzheng.Raj thinks Cheng Tian has double standards because Cheng Tian is also saving mankind.She believes they are both fighting the same battle, and gradually begins to understand each other's positions.Will saw this scene and realized that his trip to London might have been a wrong decision, so he returned directly.

Clarence tried to understand Ye Wenjie's inner thoughts and wanted to know why Vera Ye would choose to commit suicide.Ye Wenjie revealed that Vera Ye accidentally discovered the secrets related to the three-body problem in her computer.However, Vera Ye did not mention this matter to Ye Wenjie, nor did she leave a suicide note.As a result, there was a gap between mother and daughter, and they were separated forever.

The next day, Will finally understood that his embarrassing experience in London should have made him realize that what Cheng Jian needed was the support and companionship of friends like Oji, especially Oji who had a wealth of knowledge.Will realized that if he had such talents and talents, he would definitely go to Cheng Jian and dedicate himself to her without hesitation.He was sure that although Cheng Jian was working for Wade, she would never make a decision like Wade's.At this time, Cheng Jian discovered that there was a problem with the ladder plan because the detector was not designed to slow down.This means that the probe will quickly fly past the Trisolaran fleet and be unable to receive useful intelligence.However, Vader stated that the Trisolarans would definitely accept the probe because he planned to send humans up there.This decision shocked Cheng Jian.At this moment, Oji came to Cheng Jian's residence.

After Ye Wenjie is released, Clarence plans to observe her behavior outside to collect intelligence.However, Ye Wenjie just returned home.She still thinks about the Trisolarans and thinks there will be a fierce battle in a few centuries.But she also suggested that confrontation may not be necessary at all.Will planned to take his own life, but in the hallucination caused by the drug, he saw the paper sailboat given to him by Cheng Jian.This caused him to give up the idea of ​​suicide and began to seriously understand the Star Project.Eventually, he uses the money Jack left him to buy a star.
