The purplish-red pool water was constantly bubbling and steaming, seeming to be boiling.
Dozens of low-rank demons were soaking in this pool, and from time to time, low-rank demons like Roy, who needed to promote, were rushing over. Roy had only been observing for a while before seeing several low-rank demons passing the entrance and entering the pool.
The middle-rank demons lurking in the periphery did not stop them and let them enter. Moreover, seeing how the barrier blasted them away after they touched it, they seemed to want to go in again.
Roy brought Fat Tiger slowly toward the place of refinement. In this process, Roy witnessed the promotion of some low-rank demons.
