Cao Dazhuang, a retired border soldier, was forced to retire because he offended the powerful. He returned to the city with the orphans of his comrades and became a kindergarten security guard. He is honest, steady, and powerful. His biggest hobby is hiding in the corner and reading the parenting encyclopedia. Who would have thought that this seemingly harmless bear daddy was actually the "Shura" who made the underground world fearful?

In order to protect his children, Cao Dazhuang was forced to return to the world. On the surface, he is a security dad, but he is secretly investigating the truth, breaking evil formations, and beating up human traffickers. But the deeper he investigated, he found that the man behind the scenes was actually pointing to the richest family in the city, and the patriarch of this family was the culprit who killed his comrades back then!
