The red-eyed being immediately gave up on fighting as it hastily rushed back to the chamber it came from. At the same time, it seemed to have used some skill that sealed the Underworld Energy its body was using, preventing itself from leaking any more of the energy. Of course, it was just a stopgap solution. If one looked closer, one would be able to see that the being's body was still breaking apart, albeit at a much slower pace.
Frin and Duran looked at each other and nodded before both of them rushed in the being's direction. With such a golden opportunity right in front of them, they wouldn't let it pass that easily. Of course, the being's retreat gave Frin enough time to recover. That was why he was able to follow the being with Duran after the amount of damage he received.
