The soul of a modern young man traveled through the Tang Dynasty and became Li Yuanba's lost son Li Yi. He accidentally activated the divine power MAX system and gained full power. In order to complete the novice mission, he killed tigers with one punch, drove away wolves, and convinced Cheng Chumo, son of Cheng Yaojin, and Qin Huaiyu, son of Qin Qiong, in exchange for a permanent food supply for the village. After following the two men to Beijing, Li Yi alarmed the court because of his resemblance to Li Yuanba and his unfathomable strength, and was summoned into the palace by Li Yuan. During the Xuanwu Gate Incident, he single-handedly helped Li Shimin ascend the throne, and then learned the truth that his father was not dead but was taken away by mysterious forces. In the end, Li Yi refused to be crowned king, and took his mother and friends on the road to find his father and solve the mystery.
