According to the laws of the empire, the life of poor Nie Yun is not worth as much as a piece of compressed energy. He was thrown into prison for theft and turned into an experimental subject. He was supposed to die when the emperor devoured him, but because the escorting spaceship got lost, he formed a symbiotic contract with a swarm of nano bugs on a desolate alien planet, and awakened the ancient wisdom of "killing and cruelty". When Colonel Qin Yueqing led a battleship to capture him, he used the insect swarm to paralyze the battleship system and surrendered the iron-blooded captain with his absolute strength. After that, they teamed up to wipe out the pirate lairs, recruited experts from various fields, used nanobugs to transform the fleet, and developed mineral stars. They fought step by step against the empire and the interstellar consortium, and completely rewritten the brand of the experimental subjects into the logo of "Star Domain Controller".
