In order to survive on the surface, Yu Renjie, the son of the demon leader, was ordered to enter the “right way academy” that only recruits distinguished and upright disciples. The goal is to obtain a “good man certificate” that can whitewash his demon identity. This is extremely dangerous as once the identity of a demon is revealed, countless righteous knights will kill him on the spot. But on the day of registration, Yu Renjie was embarrassed to find that his personal information had been investigated cleanly. In order to hide his identity, he chose to put on women’s clothing. The dangerous and hilarious campus life is about to begin!
