In her previous life, Ling Su, the leader of the Righteous Sword Immortal, was betrayed by her best friend and used as a sacrifice. She died together with her lifelong enemy, the big devil Xie Chenyan. After the twins were born, Ling Su just wanted to be a complete "Buddhist" salted fish, stay away from disputes, and enjoy a peaceful life. Unexpectedly, the devil was reborn as the Sunshine Young Master of the Zhengdao family, and also became a gourmet master. He chased her with a kitchen knife every day, stalking her to "renew their relationship" with her. Ling Su was so annoyed that she just wanted to stay away from him, but she was involved in conspiracies again and again. As the conspiracy of the betrayer from the past life comes to light, a human sacrifice experiment that affects the three realms has begun. The two sworn enemies were forced to join forces. Amid mutual dislike and extreme tension, they used the prophetic perspective of a reborn person to solve mysteries, save the common people, and tear apart hypocrites. This is a ridiculous adventure where "I regard you as my mortal enemy, but you only want to team up with me to clear dungeons." In the end, the female protagonist uncovers the illusion and finds the right path, and the male protagonist also finds the balance point between the devil's heart and the human heart, and the two become the best "bad friends" partner to subvert the world of cultivation.
