Lin Mu traveled through time and became the old man of the Ren family who was about to transform into a corpse. At the beginning, he lay in a coffin waiting to die. He was bound to the free choice system and unlocked the spiritual swordsmanship to break free from the shackles of controlling corpses. He abandoned mindless bloodthirst and focused on the development and low-key upgrade of Goutu, and steadily transformed by devouring Yin energy. Behind the scenes, the old Taoist secretly made a corpse refining plan, and the two Maoshan Taoist priests Jiu Shu and Si Mu were investigating step by step. Mortals are afraid of zombies, but he rises against the trend, hibernates and accumulates strength, breaks away from the shackles of fate, and counterattacks from ordinary jumps to zombies, and finally steps on the path of the ancestor of zombies, overcoming the dispute between good and evil in Xuanmen!
