Winning or losing in the world is not determined by force, the human heart is the ultimate weapon
Jin Shikai, a modern psychology professor, traveled through time and became a priest of a pawnshop in a small town in the south of the Yangtze River. He is loose-minded and transparent by nature. He doesn't like conflicts in the world and just wants to live a stable life. At the same time, seven bizarre murders occurred in Jiangnan, causing various factions to blame each other and public opinion being confused. Jin Shikai relied on micro-expression insights and logical reasoning to quickly identify clues, but was framed by the person behind the scenes and became a public enemy.
Liu Xiaoxiao approached Jin Shikai in the name of investigating the case. She was initially passively monitored by Tianji Pavilion using "the truth about her father's murder" as a threat. The two gradually cleared up the fog through temptation, suspicion and joint investigation. On the surface, all the clues point to Murong Fu, but in fact it is Bai Yujing who used the knife to kill people - while manipulating public opinion to discredit his opponents, he also purged dissidents from Jiangnan in the name of eliminating evil.
