In a parallel time and space in the Tang Dynasty, when the blood of the Xuanwu Gate spread across the bluestones, Li Afu, who was working in a small drug store on the outskirts of Chang'an, was being dragged by his "old naughty boy" grandfather to watch the fun. He has no system or special abilities, but with his clever ideas, he leads a group of "fun people" to stir up disputes among the princes. While battling wits and courage with his father, "a father is kind and a son is filial", while at the same time shedding blood on the battlefield, the deep love between ancestors and grandchildren begins, and a different legend of the prosperous Tang Dynasty begins.
