In 3033, in the age of interstellar mechs, 18-year-old Su Bai has no talent for piloting mechs but is a junior mech technician. After his parents leave on a long journey, leaving him a million star coins and a dilapidated warehouse, he activates the Interstellar Combat Armor System, renovates the warehouse, and opens an interstellar repair shop. After restoring the scrapped mech Red Moon and unlocking a talent skill, Su Bai gains the SSS-rank talent Fusion of All Things and the Starwhale Breathing Technique. Talented mech pilots from all walks of life flock to him. He builds his own exclusive mech, Chaos, and becomes entangled in various conspiracies and conflicts. As he repeatedly defeats his opponents, he expands his repair shop into an interstellar fortress-level base.
