What is the ending of the movie "Cheng Wei"?

I think this film tells a simple story. As simple as the first few minutes of the film, we can infer what will happen next, the final outcome and the morality it wants to clarify. What supports me to continue reading is not to verify whether the plot is consistent with my previous inference.

But now the film industry is really full of all kinds of movies that are reasonable, intelligent and philosophical. I understand our filmmakers, who are eager to make great movies and make big stories, and relying on big IP has become the first pursuit. Ambition is really too big. But they often lack a great ability to control these "big", so there are few excellent works, most of which are neither fish nor fowl. And this "Chengwei" is like a fish going upstream.

The son of a warlord, killing innocent people, seems a bit vicious and doesn't make any sense. In order to show such an abnormal figure, Louis Koo really goes to great lengths to pretend to be cute and shout "fun" like a child. So he angered Pucheng people, especially Yang Kenan, the head of security. For a murderer, should he be released because of his powerful position, or should he stick to the duties of the head of the team? This has become the most urgent problem to be solved in this film. If released, warlords Jong and Cao Shaolin based on the abnormal psychology of "fun" will still kill all the people in the city; If we don't let go, the warlord leader will let hundreds of thousands of troops come over and remain a dead man!

The film tells the story of a generation of escort Ma Feng (Eddie Peng Yuyan Yuyan) who happened to pass by Pucheng and witnessed a murder case in Pucheng. The warlord Jong (Louis Koo), who is about to take over the county seat, killed three people, while Yang Kenan (Liu Qingyun), head of the county peace preservation corps, stuck to justice and killed Jong. Ma Feng wiped out Jong for heaven, and finally suddenly left.
