Zhou Chu (played by He Yu), a young man with supernatural powers, is naughty and rebellious. He always means well but does bad things, and is regarded as an alien by the people of Wu County. One night, Zhou Chu killed the white-browed tiger demon to save a child outside the city, but unexpectedly attracted the Tiger King (played by Chen Guokun) to bring disaster to Wu County. In the battle with the Tiger King, Zhou Chu was seriously injured. Then the Tiger King used magic to destroy the people of Wu County. Zhou Chu, who lost his superpowers, became an ordinary person. He received the kindness and care of the people, realized his previous mistakes, and understood the spirit and responsibility of a hero. Zhou Chu turned back and put on the Tianxing armor left by his father to fight the Tiger King in the final battle.
