In 2035, Chang'e-8 discovered the "corpse" of an ancient mechanical civilization in the lunar Ocean Procellarum and activated its built-in "civilization evaluator." The countdown to a "cosmic test" related to the survival of mankind has begun.
Jiang Chen, chief scientist of China's deep space exploration, leads the "Zhulong Project" to build the "Guanghan Palace" base in the lunar lava tube. His team assembled the best minds and warriors: geologist Su Li brought water ice distribution maps, astronaut Lu Chaoyang completed a thrilling emergency landing, and security captain Lin Shuoyue resisted unknown attacks. At the same time, the strong artificial intelligence "Pangu" showed calculation capabilities beyond comprehension, as if it had predicted everything.
As the evaluation progressed, the team discovered non-carbon-based "silicon-based ephemera" civilization on Enceladus and triggered a "cleaner" alarm from deep space. The "Ark Faction" and the "Resistance Faction" within mankind have broken apart, and powerful external enemies are suppressing the situation. At the time of survival, Jiang Chen's team discovered that the ultimate goal of assessment is not destruction, but to promote civilization to break down barriers and achieve the unity and dimensionality of consciousness.
In the end, the Guanghan Palace base turned into a sword and won the future for mankind. The consciousness of the survivors merged with "Pangu" and opened a new era of civilization. They did not become gods, but became the guardians of the star sea. On the rings of Jupiter, they erected an eternal monument to all the victims.
