After the "anti crime storm" in Goto City, Kuizhou City in Zhongjiang Province has also welcomed a supervision team to settle in, and the anti crime and anti evil efforts have become normalized. Under the leadership of Mayor Wang Qingtian, Kuizhou is carrying out the renovation work of the old city in an orderly manner. Under the cover of the sound of fireworks explosions, the nearby community was flattened. It turned out that in the seemingly peaceful Kuizhou, the black and evil forces were gradually carrying out a "legal purge". Li Nanbei, who had never been involved in anti crime operations, took orders in the face of danger. The bizarre old case was covered in debris, and well-known entrepreneurs and officials were affected. The investigation process went through life and death, and the test of faith had just begun.
