Traveling through the Zhenguan period of the Tang Dynasty, Su Wuming became a teacher in Hongwen Hall, teaching the sons of the founding nobles such as Prince Li Chengqian, Cheng Chumo, and Changsun Chong. Teaching teaches, how come teaching is not teaching? Su Wuming taught dragon slaying skills in his first class. Those who slay dragons must have a sharp blade in hand. Ever since, The cowardly prince Li Chengqian began to gather troops and food, ready to rebel at any time. The little demon king Cheng Chumo is also sharpening his sword, preparing to use the skill of following the dragon. Li Tai also had his own plan. Even Li Shimin felt murderous after hearing about the dragon-slaying technique. "This Su Wuming deserves to be killed!"
