Uncle Hao and Uncle You were originally brothers from the Quanzhen Sect. They lived next to each other and each opened a private school to make a living. Due to different values and personalities, the two often quarreled and became a pair of happy enemies. On this day, Uncle You got a coffin by chance, but he didn't expect that Jiang Xiaosi, who had become a demon due to the plague, was hidden in it. Uncle You and Uncle Hao had a dispute over how to deal with the demon Jiang Xiaosi. Jiang Xiaosi used his superpowers to escape in the chaos, but met Uncle Hao's adopted daughter Zhou Mingming in the kitchen and gradually became friends. The children went to the lantern festival together, but Jiang Xiaosi exposed his position by using his powers and was captured by Uncle Hao. Just as Uncle Hao and Uncle You were fighting for Jiang Xiaosi, Frankenstein sent someone to take Jiang Xiaosi away. Zhou Mingming and others followed along the road and tried to rescue Jiang Xiaosi. Uncle Hao and Uncle You stopped fighting after discovering that Jiang Xiaosi was missing and rushed to the Frankenstein base. After a hilarious rescue, Uncle Hao finally realized Jiang Xiaosi's kindness, put aside his prejudices, and everyone joined forces to defeat the villains one by one.
