The soldiers looked at the shallow wounds of the middle-aged man and just said, "To avoid any more accidents, please don't practice your abilities anymore as there are a lot of people here."
The middle-aged man had the confidence to harass him because he knew that the law and order were currently weak, but it seemed that he forgot about it when he was injured. Why would the army even take care of such shallow injuries in the current time they were in?
The middle-aged man didn't even lose an arm or anything, but he screamed too loud; that's why the soldiers came over, but they wouldn't care about such small injuries any longer, unlike before.
It's obvious that the army doesn't have enough energy to care about small conflicts that were erupting between the survivors, so they wouldn't care about it as long as it doesn't involve anything too serious, such as killing or serious injuries.
