The young man Mo Fan traveled through time and became a toad waiting to be refined, awakening the two golden fingers of infinite replication and sky-swallowing. He was recruited by the scorpion demon Heizi and given the name of Lai Bao. He relied on the spiritual loach in the pond to quickly cultivate, but he was regularly poisoned by the other party. Mo Fan secretly developed the magical powers of poison beads, charm, and tongue and arrow; he went down the mountain to steal spiritual wine to protect himself, and witnessed the torture of his own race and recognized the cruelty of the monster race. After his cultivation was sufficient, he swallowed the sunspots and replaced them, and gathered a group of little demons. Then he followed the deer demon to the underground workshop of the human race, purchased magical weapons, accepted the literate pig demon and the white snake Bai Yaoyao, and killed and intercepted the monks along the way to harvest the secret treasure. Finally, Mo Fan led his men into Black Wind Mountain to start the fighting trial.
