Gao Yan, a down-and-out young man who was kicked out by his master, inherited one of his master's most bizarre skills - the Reverse Scale Technique. This technique has an extremely domineering characteristic: whenever he formally accepts a disciple as a master, he can share a piece of the disciple's karmic fate and turn it into his own strength. If his intentions are not right, cause and effect will backfire, but Gao Yan's sinister nature makes him specialize in picking off evil people in the world, fighting evil with evil, and fighting evil with poison.
When spiritual energy revives and demons run rampant, all avenues open their gates to compete for geniuses. However, Gao Yan discovered an astonishing secret: the reason why this world is full of demons is precisely because a "devil species" that occurs once in a thousand years tears apart the cracks in the heaven. As long as the demonic species is immortal, disasters will continue. The devil is not a dead thing. It will parasitize in people's hearts and turn mortals into "stupid thieves" - they are obviously committing evil, but they don't know it because their minds are deceived.
Gao Yan traveled around the world, recruiting these "stupid thieves" as his disciples. While using the Anti-Scale Art to purify the demon species, he also gradually uncovered the huge conspiracy behind the demon species. He seems to be recruiting disciples to preach, but in fact he is setting up a grand chess game that will subvert the three realms. When the world thought he was the most despicable "human trafficker" and called him the "teacher of all evil," he laughed and said nothing - because the real evil was reaping its own consequences under his "education."
A sinister master with a family full of villains. Let's see how he uses good as bait and evil as pawns to train those stupid thieves who have been abandoned by heaven into the sharpest swords.
