In the year 2355, the world is divided into classes. The upper-class cities are as bright as the kingdom of heaven, while the lower-class slums are a dumping ground for discarded technology and broken dreams. Lin Xiuze, a young scavenger struggling to survive in the lowest dangerous area, is fighting to stay alive every day. One day, while scavenging in the restricted "Quiet Place", he accidentally fused with a mysterious metal cube - a "system core" from a lost era. Since then, he has gained a unique ability: to analyze, repair and infinitely upgrade any mechanical creation. From rusty mechanical arms to abandoned starships, everything can be turned into a ladder of power in his hands. Starting from a suit of tattered equipment, Lin Xiuze embarked on a path to change his destiny. He wanted to protect his loved ones and uncover the ultimate secret behind the core of the system and this declining world.
