The silent explosion came from a player on the safe zone's side. Not only could he silently destroy buildings, but he could also bind the explosion to a person when the small town players were completely unguarded, resulting in a young player being killed on the spot!
There were casualties on the small town side, and a white-haired player quickly killed a safe zone player to alert his companions to retreat—it should have been a retreat or some other tactical strategy because after the sound, everyone on the small town side retreated toward the center of the small town.
The town's residents had already scattered to hide in different places within the town, and although the safe zone players came in with great fanfare to find them, they clearly knew their primary task was to take care of the small town players, so they quickly chased after them.
