Li Tianxing accidentally travels to the world of Zongwu. Immediately after crossing over, he is abducted by the female version of Dongfang Bubai, who has been poisoned by a charm. He helps her detoxify the poison. After activating the side effect reversal system, Li Tianxing begins a life of turning things around.

[The host's kidneys have been detected to be overdrawn. The side effects have been reversed. Congratulations to the host for obtaining a special talent: Iron Kidneys. Say goodbye to inferiority complex.]

The world is so big that there are all kinds of strange things. From then on, Li Tianxing became that strange thing.

In order to avoid being hunted down by Dongfang Bubai, Li Tianxing was forced to travel the world, where he encountered countless witches, demons, and fairies along the way.

Dongfang Bubai: "Li Tianxing, for the torture and humiliation you inflicted on me that day in the bedroom, I will repay you a hundredfold."

Yao Yue: "Little thief, I will repay you a hundredfold for the humiliation you suffered today."

Li Hanyi: "Anyone who wants to touch Li Tianxing must get past me first."

Xu Weixiong: "Li Tianxing is my man, I will protect him in Beiliang."
