Xu Yifei, an abandoned son abandoned by his family, got married to a mysterious woman in a flash marriage to avoid being hunted. On the surface, he is a door-to-door son-in-law who is willing to be bullied, but in fact he is a "blood wolf" who makes the underground world fearful. When his wife's family faced the crisis of extinction, and when the trust he had gained for three years of forbearance collapsed in the conspiracy, he tore off his disguise and regained power with iron-blooded means. From son-in-law to overlord, from being betrayed to rebuilding trust, Xu Yifei proved with his blood that the real strong man is not about his status, but about the fierceness of his protective heart. This is a passionate legend about tolerance and explosion, betrayal and redemption.
