Lin Mo transmigrates into the body of the Qingxuan Sect's most useless servant and awakens the Reverse Cultivation System.
While others meditate to refine their qi, he has to do square dancing to raise his cultivation. While others give gifts to curry favor, he has to steal an elder's teapot and use it as a chamber pot to unlock skills. While others respectfully pay their nervous, trembling respects to the sect leader, he has to clap the man on the shoulder and call him “Old Li” to claim rewards.
Everyone at the sect thinks he's crazy, until they realize something is off. The elders secretly learn his square-dancing moves, and their bottlenecks loosen immediately. The sect leader gets so angry at him that he coughs up blood, only to comprehend a new cultivation method. The icy senior sister gets pranked into social ruin, but her cultivation skyrockets.
Before long, the whole Qingxuan Sect has gone off the rails. Sword cultivators wave their blades while dancing, alchemists chant slogans as they make pills, and even the sect leader secretly follows Lin Mo's lead and practices doing everything backward.
Later, neighboring sects show up. Then come the great figures of the immortal world. Even the ancestor who's been asleep for ten thousand years is roused. They haven't come to kill Lin Mo. They've come to become his disciples.
Lin Mo looks completely innocent. “I just wanted to keep my head down and survive. Who knew you would all start copying me?”
