What is the ending of the TV series?

Hu Qiang was finally caught. Hu Qiang, as the first thug under Ma Su, passed the tests at different levels. Not to mention, he is the hero who discovered Roffe's undercover identity. Master Jie can do business abroad with peace of mind without his credit. It is precisely because of this that Hu Qiang can win the trust of Mas. Otherwise, Ma Jiejie won't let Hu Qiang play tricks under his nose. It will not arrange to provoke the relationship with Du and then get rid of Du.

Seeing that his position was in jeopardy, Hu Qiang and Adan jointly kidnapped the ROK and shot Gu Tao twice. In the face of irrefutable evidence (cameras and videos) and Mas's inquiry, Hu Qiang admitted these things without hesitation. I thought it would be like before, and nothing would happen. However, what Hu Qiang never expected was that Gu Tao turned out to be Mas's brother. This makes Hu Qiang's frankness more like the rhetoric of fear of punishment. In the face of each other's cold questioning, even Masje began to believe that "Hu Qiang was the real murderer who killed Gu Tao". As for the fact that Hu Qiang was taken away by the police after his death, Mas hastily withdrew without asking too much.

In the final analysis, this is because Hu Qiang was not honest at first, and Mas was no longer suspicious. With Mas's trust in Hu Qiang before he quit, if Hu Qiang can tell the truth before the evidence is taken out, maybe the latter thing will not happen, and the identity of the knight-errant and the ROK has long been exposed.
