The apocalypse arrives. The male lead drains his strength and relies on a super farm system to supply the base and three powered sisters he raised. Yet he is seen as a powerless non-combatant, treated unfairly, manipulated by a scheming younger brother, and driven out of the base. In despair, he unlocks full system access and can recruit zombies as laborers. He takes over the abandoned Qinghe Farm, directing zombies to clear land, farm, raise livestock and stockpile massive supplies. Back at the old base, crops wither and famine breaks out without his support. His former kin repent and beg for cooperation, but he has built his own apocalyptic home and will not repeat past mistakes.
