The owner of Wanma Hall, Ma Kongqun, set a banquet at Meihua Temple to kill the entire family of the God Blade Sect Master, Bai Tianyu, consisting of 21 members. Bai Tianyu's illegitimate son, Ye Kai, grew up under the care of his master, Li Xunhuan. Ye Kai is cheerful, kind, and compassionate, winning the deep affection of his master. His master imparted to him the skills of throwing darts, and under his guidance, he has long forgotten the 'grudge of his father's murder.' To take revenge, Hua Baifeng adopted an orphan, Fu Hongxue, training him to be an instrument of revenge. More than twenty years passed, and Hua Baifeng deemed the moment right, sending Fu Hongxue to Wanma Hall to kill his enemy, Ma Kongqun. Upon learning of this, Ye Kai's master urged him to settle the grievances of three generations. For more than twenty years, Ma Kongqun has been on guard against the descendants of Bai Tianyu seeking revenge, and he has repeatedly sent assassins to kill the stranger, Fu Hongxue, in the small town, but to no avail. Fu Hongxue fell in love with a prostitute named Cui Nong in the town and tracked Ma Kongqun with her. Unfortunately, Cui Nong was killed while trying to protect Fu Hongxue. Just as Fu was interrogating the assassin, he was killed by Ye Kai's dart, leading to mutual suspicion and hatred between Fu Hongxue and Ye Kai. At this moment, Shen Sanniang, who was once a maid of Hua Baifeng, arrived to inform them that all this was Ma Kongqun's scheme to incite them to kill each other, achieving his goal of killing two birds with one stone.
