Fifteen armored combat skiffs split into three formations midair, flying silently toward the demonfolk tribe. They soon reached their designated battle positions.
The three formations surrounded the demonfolk tribe from the north, east, and south. The First Regiment of the Second Division, responsible for the east, began accelerating ten miles away, entering the Abyssal Knight patrol area and racing toward the city wall.
