1, the main content: the mirror is mainly about the main character invented a kind of super-string computer, computing power is so strong that it can simulate the creation of different universes and all the things that happened after it, not coincidentally it happens to be the main character simulated the model of the universe where we are, using the model computer can see the past and future of anything in the human world.

But this would ultimately lead to a world of complete transparency, where anyone can know anything about anyone's behavior, which would inevitably lead to death, so the hero gives up on publicizing the technology. But he also calculates that mankind ended up inventing the technology and led to the eventual demise of human society.

2. Theme: A mechanical and completely transparent form of society cannot exist, at least not in the human world. Also logically, the computing power required for such technology is infinite, and computers with such power have a total amount of matter any way you look at it, so it's impossible to compute infinite amounts of data, so there would be a limit to the ability of computers to predict the future.

The earliest science fiction novels

The earliest original science fiction novel in China was "A Novel of the Lunar Colony", published in 1904, by the author of the pen name "Arakan Fishing Man". Xu Nianci, the founder of China's earliest purely literary publication Novel Forest, not only translated foreign science fiction novels, but also wrote his own science fiction novel, Mr. Tan, the new Mr. Falcon. The famous writer Lao She also wrote a novel with science fiction colors called "The Cat Town Story".

In 1949, after the founding of the People's Republic of China **** and the country, science fiction literature is still developing in a thriving manner. The literary genres of this period were closer to science fiction, mostly popularizing scientific knowledge and preconceiving the bright future of the socialist country to readers of lower ages.

Thematically, it was closer to the style of Soviet "socialist literature" of the same period. During the Cultural Revolution, the development of science fiction literature in mainland China came to a standstill.
