The Independent Commission Against Corruption received a complaint that the owner of Fu Xiang Building suspected corruption in the tendering process for repairs.After investigation, it was found that among the companies bidding for the Fuxiang Building project, in addition to Lin's Engineering, many other companies suddenly withdrew their bids due to different reasons, and it seemed that Peng Shao and Big K, who had gangland backgrounds, were involved.Situ Qiwen pieced together the entire corruption chain from various clues, and finally discovered that the mysterious operator behind it was Huo Wanlian (played by Zheng Zeshi), the boss of “Wannian Construction” who was hiding in the Chinese medicine clinic every day and directing everything.Jiang Jianqiu and the entire team of investigators were ready and carefully planned, hoping to collect evidence of Huo Wanlian's crime through Lin Qiang, the boss of “Lin Engineering”.However, unexpectedly, Lin Qiang was timid due to fear on the spot, putting the entire plan in jeopardy.
