Shen Fei, the eldest son of the Shen family, disliked martial arts since he was a child but was kind-hearted. The patriarch was injured by an evil spirit. When he passed the throne, Shen Fei was too weak in martial arts and was opposed by the family elders. The patriarch's younger brother conspired to assist his son, the ruthless Shen Xinghe, to ascend the throne and murder Shen Fei's family, including the good girl Tang Wanting who had always had a crush on Shen Fei. Shen Fei lost his family and was also attacked by his crush. The goddess Mengling betrayed her and once wanted to commit suicide, but was rescued by the family elder at the risk of her life. She was taken in by Shen Fei's third grandfather Shen Chong, who had been expelled from the Shen family many years ago. Because he liked this grandson, he accepted Shen Fei into the Lai Zimen, and finally took charge of the Lai Zimen. He used the five swords to avenge a sea of blood and retired to become a street rogue. Many years later, he came out of the world again because of a bizarre marriage.
