How Come This World of Immortality Has Become a Nest of Corpses?

Before traveling through time, Li Liang thought that the world of cultivating immortals was like this: An elder with an immortal spirit, a blessed land full of spiritual energy, and a boss who flies with a sword. After time travel... Hehehehe... Fellow disciples were wandering among the ruins with gray faces, dull eyes, and red liquid hanging from the corners of their mouths. Tianyun Sect became a corpse nest. Even the spiritual energy was contaminated by the death energy, and all surviving immortal cultivators were unable to practice. Li Liang: How come this world of immortality has become a nest of corpses? ? ? Fortunately, he awakened the Pure Spirit Body and the Corpse Control Technique. Pure Spirit Body: The death energy cannot get close to the body, and he is the only person in the world who can practice normally. Corpse Control Technique: Kill corpses to cultivate, refine corpse cores, and plunder all cultivation and memories. Others are living in a nest of corpses. He levels up in the corpse den.
