At the annual Tianjin Reminiscence Party, the clown used magic to steal the golden gown. The descendants of Tianjin's three major magic families: the Fushou Tang Clan, who are good at hand speed and sleight of hand, the Jiban Li family, who are good at making magic mechanisms and props, and the Shuijing Qi family, who are good at breaking all kinds of illusions. The descendants of the three major families teamed up to launch a series of chases against the clown, unlocked the secret of the golden gown, and found the magic secret book Yunjilu.
