Mei Wuji died immediately after falling to the ground. He was resurrected after being injected into his body with three rays of ghostly light, awakening the power of the Netherworld Emperor's soul. He has a fate of three disasters, six tribulations and eighteen calamities. Along the way, they encounter disasters such as the Black Mountain Grandma, the black dragon snake, and the bloody sky thunder. Meishan Daozong believed that Mei Wuji was a monster and wanted to sacrifice him to heaven. Chen Jizhen brought the Yin Yang Soul Suppressing Coffin to the rescue and took Mei Wuji out of danger. Mei Wuji followed Chen Jizhen to practice, while controlling the power of the Underworld Emperor in his body, resisting the backlash of the remnant soul, and killing demons to solve the disaster. Accidentally discovering the treasure of the underworld, the Human Reincarnation Disk, escapes from the underworld, causing harm to the world, allowing all the dead to be reincarnated with their memories.
