Ruan Zhi, the leader of the northern mercenary army, bets on revenge with a marriage - the target is Jiang Jin, an illegitimate son who is regarded as a mad loser by the world. Everyone was waiting to see Ruan Zhi's joke, but little did they know that the seemingly weak Jiang Jin was actually a top hacker boss. The two are in extreme tension, two-way redemption, and a perfect combination of two powers. When Ruan Zhi personally gave him the bell, she realized that it was not the wild dog that had been tamed, but the wolf king who had already chosen his master.
