Chen Xiaoyi traveled through time in the examination room for the teacher qualification certificate and became Xie Zhaoyun, the fourth prince of the Zhou Dynasty. He naively thought that he was the proud man of heaven.

A smoke bomb set off to protect his biological son.
The real prince is the guards he calls around.
Concept: the collision of modern thought and ancient civilization.
