Boom!
In the parking lot behind the technology building, a ball of fire expanded and illuminated the area.
Bai Chen and the others vaguely saw merfolk that had hidden pretty well. Their grayish-black scales reflected the crimson glow.
With the help of the many obstacles in the city ruin and the lack of a wide field of vision, they had already advanced to an area 100 meters away at some point in time.
Jiang Baimian's rocket didn't cause any damage because she didn't know the enemy's exact location.
But before the explosion subsided, rampageous firepower poured from all over the defensive line.
The firing continued as cannonballs rained down one after another, forcing the merfolk to hide in the natural fortifications around them. Five to six corpses were left behind.
Right on the heels of that, Long Yuehong, Han Wanghuo, and the others immediately had difficulty breathing again.
