It is the fact that China may not have a great atmosphere for science fiction, but the “Three-Body Problem” series is a great science fiction novel; its author may not be a literary writer with profound literary skills, but a novelist who is highly accomplished and versed in physics. It is the author Cixin Liu who alone let Chinese science fiction novels break through the barrier of the dry land. “We are all bugs in the gutter, but someone has to look up at the stars.”This book is a starry sky, showing people the mathematical principles, the laws of the universe, and the imagination of the future, further describing a world between reality and falsehood.

When hearts have been desperate and humanity has been annihilated, people have pinned their hopes on the alien civilizations with high-tech means, hoping that they can save humanity from the trough of moral. Human beings in the universe are like children in the dark, inviting a bonfire, and still shouting “I am here, I am here...”. The exposure of the coordinate of Earth eventually resulted in an unprecedented interstellar invasion in human history. The enemy of human beings—the fleet of three-body civilization will arrive at Earth almost 400 years later, but because the basic science of Earth was locked by the intelligent particle launched by the three-body fleet, humans could only rely on their wisdom to resolve this life-and-death interstellar crisis.

In addition to the pure science element, the series of “Three-Body Problem” also focuses on the shaping of human nature; In war times, humanity is the most vulnerable to be trampled. Human beings are selfish: no matter how advanced the technology is, the inferiority of selfish always exists in human genes, but humans also have a great side: love, kindness, compassion...However, in front of life and death, the great side is brittle. Any words related to democracy, freedom, and equality have no meaning, and survival is everything. In the battle between humans and the alien civilization, the “facing plan” instituted is really a great decision: four people chosen from all mankind who are allowed to use all resources of human beings, hidden their true ideas behind their action in order to confuse the intelligent particle, using their intelligence to fight the force of the alien civilization. Logic, one of the four chosen people, even in the case of failure of the other three, encountering the trough, and being squeezed by all mankind, he still came up with the dark-forest rule, by announcing the coordinates of the three-body galaxy and the solar system to attract other high-level civilization to attack since each civilization is a threat to another, forcing the three-body fleet to reach a contract of peace with humans.

This is a perishing plan for both Earth and the Three-Body civilization, it is crazy but effective. In front of an alien race that considers survival more than anything else, it is arguably the most threatening means, However, after humans gained peace, the idea was gradually vetoed by the majority that it committed crimes against humanity—the idea saved human beings are considered crimes. There have been many such episodes in this novel, and it reminds me of the plot in Ender’s Game that the protagonist rescued human beings from the Zerg invasion, but he was considered as a notorious executioner. From my perspective, all these express one meaning: the biggest obstacle to human self-rescue, is always derived from humans themselves. This novel reveals that in front of irresistible disasters, mankind needs a strong government and they need to be fully committed to a goal with the leadership of the government.

Human beings are really strange animals. In the disaster, behaviors of unimpeded to survive can be found everywhere, but people can also initiate the modern Renaissance and regain humanity from the pain; some people will be unscrupulous and take all means regardless of whether they are good or not for their survival, but there are still people who will step forward and voluntarily sacrifice at the moment of life and death. No matter how long the time has gone, human nature is always complicated. However, as a member of team human, it is still necessary to have confidence and hope about this civilization: after all, these are the most powerful weapons of mankind in the universe.
