Lin'an City during the Chunxi period of the Southern Song Dynasty. On the surface, it is a prosperous place where "the warm breeze makes tourists drunk", but in reality, the powerful prime minister Han Yuzhou is in power, the party struggle is fierce, the Kingdom of Jin is eyeing it, the Jianghu Cao Gang and the street gangs collude with the government for their own interests, and the people are boiling with resentment.
The "dragon head guillotine" left by Bao Zheng was not a simple instrument of torture. It contained secret maps pointing to the "Treasury of Honest Officials". This is not only wealth, but also records the irrefutable evidence of the collusion between the court and the Jianghu for hundreds of years. At that time, the descendants of the Bao family dispersed due to the Jingkang Incident, and the secret map was also lost. However, now they have reappeared because of a "tribute tea case".
