Oh No! I've Transmigrated Into a Corpse

What do you do when you transmigrate into a corpse? Asking for a friend. It's kind of urgent. When Lu You wakes up in a mass grave and realizes he's become a fresh corpse, he's completely stunned. Rotting companions lie beside him, crows circle overhead, and cultivators in the distance are hunting “living corpses.” Luckily, by a twist of fate, he obtains fragments of a supreme treasure left behind by the Taiyin Divine Lord. Branch of the Moon Laurel Divine Tree: helps absorb Taiyin energy; Fragment of the Taiyin Veil of Darkness and Light: conceals one's form and shields one from the workings of Heaven; Fragment of the Taiyin Dao Disc: manifests a fragment of the Taiyin Dao Fruit and contains a remnant of the Great Scripture of the Primordial Taiyin Cycle of Darkness and Light; From drawing in energy beneath the new moon to condensing the Dao beneath the crescent, from returning to truth beneath the full moon to mastering the laws of darkness and light, from a living corpse that shambles like the dead to the Taiyin Divine Lord who commands the power of Taiyin! Carrying on the legacy of the Taiyin Divine Lord, Lu You walks out of the mass grave. He crosses the Four Realms and Four Seas, witnessing the collapse of the netherworld as it transforms into a Yin Domain and falls into the mortal world. The dead can no longer reincarnate, corpses rise as zombies, and the human world becomes a living hell. He also ventures through forbidden wastelands left behind from antiquity, where he feels the terror and despair of the ancient immortals' destruction. He even delves deep into the Great Abyss of Chaos, faces the undying will of the primordial gods and demons, and witnesses the eternal destiny of Taiyin and Taiyang.
