Xiao Xingchen, the seventh prince of the Qin Dynasty, was sent to Dayan as a hostage at the age of seven. He pretended to be crazy and acted like a fool for ten years. He secretly awakened the sign-in system and cultivated to the martial master level. Returning to the capital, faced with the frame-up of his brothers and the indifference of his father, he uncovered the conspiracy step by step, summoned famous generals, unified the princes, and finally ascended the throne and proclaimed himself emperor, achieving great achievements for the ages.
