Human beings have left the earth for a long time, and now only the technological "residues" left by humans are left on the earth.
These remnants still follow the rules and traditions created by the ancient human ancestors, and generally live happily. Everyone lives in peace, treats each other friendly, and helps each other.
Except for a handful of unplugged robots.
Because they are too tossing, and with the blessing of powerful ancient technology, the tossing of these robots often brings "pain" to other races.
This time, it's the turn of the protagonist, the robot, to go out and torment people.
