Before his rebirth, Ye Mian's brother was an excellent man. He gave everything in his family first, but in fact he misunderstood his parents and brother. He never speaks his mind. One night, he went out for air, had an accident and was reborn in an overhead dynasty.

The whole novel revolves around Ye Mian's schooling in ancient times, such as being naughty, getting up early for school, kneeling in exams, drinking and having fun, being short of people at home and falling in love.
