I want to know the main contents of Liu's Three-body and the synopsis of the main characters' stories.

1. The work tells the information exchange, life-and-death struggle and rise and fall of the two civilizations in the universe.

2, the main characters

A professor of physics (three-body) began to understand the virtual civilization in the game "three-body" by entering the scientific boundary. The nano-materials leading this research also provide technical support for the Earth Defense Forces to obtain e to information.

Yun Tian Ming: (Death will live forever) He was doomed to die as soon as he got cancer. Before he died, he was deprived of all life-related desires, such as love and affection. His relatives want him to be euthanized to reduce the burden of life, but the only person who loves him in the world wants to take out his brain for human space experiments.

Due to the admiration of college students, Yun gave up euthanasia and went into space alone. He got some scientific and technological information in the three-body fleet and sent it back to earth in the form of fairy tale metaphor.

3. synopsis of the story

The first part: It didn't reveal the picture of cosmic civilization, and the two civilizations themselves didn't realize this picture, but just unveiled the tip of their veil.

The second part: After using magic technology to lock in the science of the earth people, the huge cosmic fleet made a brutal attack on the solar system in an attempt to clear the earth civilization. In the face of unprecedented crisis, the earth people who have experienced countless hardships have formed the same huge space fleet. At the same time, they made use of the fatal flaw of the three people's transparent thinking to formulate a mysterious "side wall plan."

Three parts: With the passage of time, the dark forest theory has formed a new theory, that is, deterrence theory. Under the deterrent degree of more than 90% in Luo Ji, three-body civilization dare not make a move. At this point, the three-body civilization and the earth civilization reached a state of balance. But with the aging of Luo Ji, it is necessary to choose a new "swordsman" to maintain this balance.

Extended data:

Three-body phenomenon and China's science fiction.

The characteristics of these excellent sci-fi works in Three-body indicate the broad prospects for the development of sci-fi literature. Unfortunately, due to various reasons, China's science fiction has not been well developed for a long time. There are few works that can reach the artistic level and reading appeal of Three-body, and there are few authors like Liu.

In other words, the success of Three-body is an exception to some extent and cannot be copied. The award of "Three-body" not only has a pleasant positive incentive effect, but also may bring some blind optimism. It is conceivable that even if a China scientist has won the Nobel Prize now, can human beings think that the overall strength of China's scientific research has stood in the forefront of the world?

Therefore, when people begin to pay attention to China's sci-fi creation with a certain optimistic tendency, they should reflect on the unfavorable factors that restrict the development of China's sci-fi. In fact, these factors are various, both institutional and cultural.

For example, the lack of comprehensive understanding of the positive role of science and technology in the process of social and human development and the lack of humanistic care related to science and technology may be an important constraint.
