"Yes, that is correct," Gram didn't deny it. "But it is also a great place for those who cultivate Water-related techniques or have skills that need such type of energy. During the critical point of the Glacial Overflow, provided that you manage to survive it, you can gain a lot from taking it head-on."
"Oh!" Rean looked around and nodded. "So that's why we have so many cultivators, demon beasts, and spirits here, uh? Not all of them are crossing the corridor."
