On a stormy night on Dragon Island, Xiao Chen achieves a sweeping victory in a martial arts competition, only to be ambushed by a hidden gunman. He catches the bullet with his bare hands and swiftly subdues the attacker, who immediately chooses to take his own life, leaving the mastermind behind the attack a mystery. His master appears and tells Xiao Chen that his five years of training are complete and that there is nothing more the island can teach him. However, Xiao Chen possesses the rare Pure Yang Overlord Physique, and the yang fire within his body will threaten his life within half a month. Only a Nine Yin Mystic Physique can balance it. His master gives him a marriage contract and a black card, revealing that Su Qingxue, the president of the Su family in Jiangcheng, possesses precisely the Nine Yin Mystic Physique he needs. Xiao Chen accepts the marriage contract, boards a fighter jet, and heads for Jiangcheng, beginning a journey where a marriage pact and a looming crisis intertwine.
