When he woke up, a sexy beauty in ancient clothes was shaking the bed.
Xiao Ce had traveled through time!
The good news was, he had traveled into the body of the Crown Prince!
The bad news was, this Crown Prince was a bit useless, even the dogs in the Imperial Palace could pee on him.
The Emperor wanted to depose him! The other Princes wanted to kill him!
Starting off framed, surrounded by wolves, how could he break the situation?
