Shen Mo, the chief of the Punishment Department of Dasheng, was involved in the court whirlpool due to an unresolved water transport case. When revising the law, he dealt with the two parties of Prince Qi and King Wang, and the forces of Jianghu, using the code as a blade to engage in a desperate game between the provisions of the law.

This is a legal battle that does not see gunpowder, but determines the fate of the empire.
