Lin Qianjie, who had done evil for ten lifetimes and was full of evil, was supposed to fall into the Abi Hell and never be reincarnated forever. However, due to a golden thunder, he was summoned to heaven and became the new "evil tester" in heaven - using a body of pure evil to test the evil-suppressing formation that can subdue evil thoughts. He accepted the Jade Emperor's bet like a gambler and spent three months in heaven: he broke into the peach garden to challenge Sun Wukong, went to the Yaochi to expose Chang'e's obsession, stole elixirs, and pulled the strings of marriage, turning the strict rules of heaven upside down. But behind this unruly attitude, there were kind thoughts that even he himself was unaware of. Xian'e Azhi, who was guarding the Nantian Gate, actually saw through the softness behind his evil appearance at a glance. When the evil-suppressing array was activated, the sins of ten lifetimes turned into illusions of obsession and came over. At the moment when Ah Zhi's shadow was on the verge of death, Lin Qianjie's original intention that had remained unchanged for ten lifetimes was finally shaken. This adventure in heaven in the name of evil finally became a journey of self-redemption. He left behind the bad reputation of ten lifetimes and returned to the mortal world with Ah Zhi. In the sunset and sweet-scented osmanthus cake in the small town in Jiangnan, he lived as a flesh-and-blood Lin Qianjie. It also made the three worlds understand: there is no boundary between good and evil, and a different thought can lead to different returns.
