It turned out the Heaven-Inquiry Sect had set up a barrier here, confining the Monster Beasts within this section of the river.

Xiao Yifeng sensed it for a moment. The barrier's strength could probably withstand an attack from a seventh-level Qi Refining cultivator. No wonder the Heaven-Inquiry Sect had to cull the Monster Beasts periodically; they were afraid a Monster King would emerge.

"Junior Sister Ling, I believe this barrier was set by our Heaven-Inquiry Sect. I think we should be able to pass through it with our Command Tokens. The situation inside is unknown, so let's turn off the light from our Water-Repelling Pearls for now to avoid attracting a swarm of Monster Beasts."

"Alright, Senior Brother Xiao, I'll listen to you," Ling Sisi said.
