When the current secretary of the Jinchuan Municipal Party Committee talked to Qu Jianghe, he mentioned the former secretary of the municipal Party committee. At that time, the mining disaster happened at the hands of the former party secretary. However, there was no evidence at the time, so their conversation was very cryptic, and they did not name them. Wu Zhenggang's identity as a behind-the-scenes boss didn't come to the surface until the end. Zhuo Zhuo and Xia Zhongtian secretly went to Meng Chuansheng's villa. Xia Zhongtian learned that Little Hong Kong had come to Jinchuan in advance. He guessed that the big man was about to show up, so he contacted Qu Jianghe, but Qu Jianghe was taken away by the procuratorate for investigation, so he could only find Zhuo Zhuo. Zhuozhuo risked his life to capture evidence of the meeting between Wu Zhenggang and Meng Chuansheng.
