Synopsis: Lin Mu transmigrates into the body of Old Master Ren. The moment he opens his eyes, he finds himself a corpse about to be burned, with a corpse-controlling lock planted in him by an evil cultivator! After binding to the Free Choice System, he chooses to lie still and gain spiritual awareness, then cuts the chains and breaks the seal with his sword, refusing to drink blood to steady his mind. Facing Uncle Nine’s talismans, Wencai’s stupidity, and the black-robed Taoist’s schemes, he proceeds cautiously, digging underground to hide and grow stronger. On this path of undeath, he insists on choosing his own way, rising from a lowly insect in a coffin to an immortal Zombie Sovereign!
