In the past, Lin Fan, the king of the North, looked down on the disputes and turned into an ordinary deliveryman who just wanted to live a stable life. He accidentally rescued Mu Wanqing who was being plotted. The old man of the Mu family thought of his responsibility and facilitated the marriage of the two. Others looked down upon and made things difficult for him, but Lin Fan showed off his superb blood-locking medical skills to save people, and he felt proud in public time and time again. His ex-girlfriend Long Qingyue traveled thousands of miles to find him and invited him to take care of the family's southern property. The leader of the underground forces had evil intentions to kidnap Mu Wanqing, but Lin Fan took action to save her safely. Subsequently, his fellow apprentices became obsessed with stealing ancient forensic medicine records and practicing black magic. Lin Fan resolved the crisis and quelled all the troubles in the city. He once again traveled far away to find his mentor, and kept his true heart and morality in the bondage of two deep love relationships.
