Li Heng piloted an old spacecraft on a mission to salvage lunar debris, but accidentally activated the Star Destroyer "Sky Patrol" left behind by an ancient civilization.
At the moment of recognizing the master, the silicon-based empire on the edge of the galaxy woke up simultaneously, and a cold mechanical voice announced to the entire universe: "The inheritor of the fire of civilization has been detected, and the elimination procedure will be executed."
A huge muzzle opened on the back of the moon. Li Heng raised his hand and tapped the star map: "Sky survey, activate planetary annihilation mode."
After a beam of light penetrated the earth and the moon, he turned to face the frightened heads of the earth: "From today on, mankind will be protected by me."
