Xu Hei, who traveled through time and became a black snake on the first level of Qi refining, unexpectedly killed the reborn Immortal Emperor, obtained the demon clan's most precious treasure, the Demon God Cauldron, and perfectly transformed into the innate Taoist body. He dealt with the human monks and teamed up with the demon master Tianmo Sanren. From being hunted to taking the initiative, he leapfrogged and forcibly killed the elders of the Snake Sect and the monks of the Moving Mountain Sect. In order to protect the Valley of Ten Thousand Snakes and protect Taoist companion Xu Bai, Xu Hei condensed the reverse scales to transform into a dragon, and his cultivation soared. Finally, he led the wild giant elephant to destroy the snake-catching sect's branch, starting the path to the rise of the Demon Emperor.
