In the future, human footprints have spread across half of the solar system. Steel "star cities" are scattered around major planets and among originally empty planets. Human genes have also been modified. Their powerful brainpower, physical strength, and various high technologies allow them to break through the limits of their bodies. By chance, L (real name Liu Dufan), a school officer of the Human Alliance, joined an "organization" on Europa that held "secrets" about the origin and development of mankind as well as many high technologies. He also learned about the "enemy" - an alien empire that is more powerful than humans. After that, he and the leader of the organization, his boss General M (whose real name is unknown)
Zhou) and organization members and partner X (real name Shen Yuheng), with the help of a mysterious figure, helped mankind resist the enemy, but in the end mankind lost, and only the last bit of mankind was hidden among the enemies. They searched for the remaining humans, and helped the "Lowa tribe" who were almost exterminated by the empire. Finally, they passed through the wormhole and worked together with everyone to arrive at a planet called "Ice Star" to rebuild civilization. But after that, people discovered a shocking secret...
