[Apocalypse + mecha + black technology + resourcefulness + cold weapon combat ]
In 2123, the human population dropped sharply after the nuclear war, and the world was ruled by alien high-dimensional life forms.
Alien civilization sends "supervisors" to monitor humans, restrict the use of thermal weapons and thermal energy, and also sends "destroyers" to punish violators, trying to turn the earth into a "nurturing place."
Liu Ming, a survivor of human ruins, survives in PlayerUnknown's Battlegrounds, leads scientific and technological archeology in human ruins, and drives mechas to fight against oppression.
