In prison, Yi Ding and Sun Jian had a political conflict with their cellmates because of their key signature, so they became friends. Sun Jian politician told Yi Ding about his prison experience and suggested that Yi Ding find so-called friends on the road after he got out of prison. Dong touched two situations. First, he Wen Bin left the city before Lu Huan was killed, and has not come back yet. Second, Zhang Dali acted as a mediator in the underworld after Lu Huan was killed, and often held banquets to entertain guests and friends.

After he got out of prison, Ding Yi found Yang Degang, as Sun Jian politicians said, and wanted to do something together. Unexpectedly, Yang Degang politely refused. Yang Degang's Zhu Xiaojun took a fancy to Yi Ding's courage and hoped that Yi Ding would put up a banner on his way with Yi Ding himself. Through investigation, the police combined the two cases and found a breakthrough. After consulting with Dong, he decided to take an operation and arrange Du Zhenghai to buy a batch of guns abroad.
