Xu Mu traveled through time and became a brainless villain, letting the Dragon King's sister live outside at the beginning. Fortunately, he awakened to the justice system, kicked the doghouse to pieces, and began to transform into a wife-doting maniac to restore the relationship with his wife. He punched Lin Yang, kicked Fang Chu, and relied on the justice system to obtain skills and elixirs. Not only did he pry away the Dragon King and the protagonists, but he also subdued the Dragon King's three thousand soldiers, and finally changed his inevitable fate and defeated the Dragon King.
