Xiao Yun, a refugee from Qingmang Mountain, was born as humble as an ant, and was bullied all the time. When he was about to die, the demon source jade in his neck awakened, attracting the original power of the demon clan into his body, and he embarked on the path of heaven-defying demons. From refining the body with residual techniques, building foundations and slaying enemies, to unifying the Demonic Way of the Western Desert, and then to overcoming the Alliance of Righteous Paths, he used the Heart-Eating Demonic Sword as his edge and based on the "Ten Thousand Demons Manual" to defy the odds and transform into a god in the battle between immortals and demons. After ascending to the demon world, he fought against the wild beasts and defeated the seven demon kings. He unified the demon world with his absolute strength. He finally broke through the shackles of heaven. From an abandoned son in the dust, he climbed to the top of the world of immortality and became the only demon lord in all eternity!
