Xu Linfeng, a timid and socially fearful young man, has a crush on the company goddess Jiang Wanyi, but he doesn't even dare to talk to her. One night when he came home from overtime work, he accidentally bumped into a female ghost in red. He was frightened and fainted on the spot, but accidentally activated the "Yin Yang Secret System".
The system is venomous and nonsensical, and each task it issues is more outrageous than the last.
In mission after mission, Xu Linfeng and Jiang Wanyi experienced all kinds of strange things and solved countless mysteries, and the two gradually developed a deep relationship.
It's interesting and worth watching.
