At the critical moment of life and death, the scrap metal suddenly popped up on the holographic screen: [The core of the SSS-class starship, the master was successfully recognized. ] He was stunned for three seconds - in the doomsday wasteland, a garbage man was bound to the top AI brain and maintenance system in the universe. From scrap metal to Star Destroyer gun barrels, scraps that others regarded as worthless were transformed into alien mechas in his hands in minutes. "Wow!" When the former enemy stepped on the mechanical armor to seek revenge, Shen Yuan silently activated the stealth warship made of eight parts under his feet. The next second, the entire base's sirens were frightened.
