Li Wujiu, an abandoned disciple of the Righteous Path, was expelled from the sect due to the "backlash of inner demons" and became a handyman at the bottom of the Demon Sect. He cleaned corpses, fed poisonous poisons, and was bullied every day. Until one night when he cut off his obsession with a knife in a mass grave, he unexpectedly awakened the taboo talent [Kill My Dao Heart] - which can cut off emotions, longevity, cause and effect, and even destiny! From then on, he rose up against the will of heaven as a handyman, killing fellow sects to steal skills, killing elders to steal secret scriptures, and killing holy sons to gain fame. The demon sect regarded him as a mad dog, and the righteous way called him a disaster star. All the heavens and worlds wanted to get rid of him, but he only said coldly: "If the way needs me, If you become a demon, then kill this way!" From the bottom of blood and fire to the top of the world, he proved his feelings with ruthlessness, and cut through the way of heaven with himself, and finally wielded the last knife at the end of chaos - not to defeat heaven, but to cut off the shackles of "I" and achieve true transcendence.
