[Time travel female college student x fake guard and real prince]
Normal school students bravely enter the ancient palace.
Chen Xiaoyi traveled through time in the examination room for the teacher qualification certificate and became Princess Li Siyan of the Zhou Dynasty. She naively thought that she was the proud daughter of heaven.
What she didn't know was that she was actually a fake princess, but a smoke bomb that Concubine Xiao had put out before she died to protect her biological son.
The real prince is the bodyguard who calls around him.
