Boom!
A huge explosion occurred inside that hole, which was the hole in its body. As a result, there was no tough skin that could stop it anymore.
The explosion hit the inside of the alien's body and disintegrated the flesh around it, leaving nothing but a single core and the tough skin.
Selena had also taken down the warrior class alien on her side. She first took a glance at the current situation.
Surprisingly, Risa was surpassing her limit.
When she looked left and right, most of the aliens had been taken down. Only those above the juvenile class mutant or mature class were able to survive. Even then, they had suffered a massive injury.
Risa alone had killed around three hundred aliens. At the same time, she was sweating like crazy. She would probably exhaust all her ena in two or three minutes.
Hence, Selena said nothing to Risa. Instead, she turned around and shouted to the rest, "Retreat to the top. We have to check on the other girls!"
