A Narrow Exit

What happened?

Why did the burrow entryway suddenly become so narrow?

The narrow passage opening indicated a vast number of biological creature groups inhabiting within the burrow space of the upper layer, great enough to suppress the Snowthreads. Of course, such a large cumulative native group posed a significant threat to the Demon-Hunters.

"What should we do, continue to go up, or withdraw to a burrow space and look for another way out?"

Grimm's eyes flickered and he recollected the scene of previous burrow space. In a deep voice, he muttered, "The last burrow space had three passage openings. Two of them were about thirty meters and seventy meters respectively. They are not suitable choices. As for the last burrow space... "

After serious consideration, Grimm decided to go into this relatively narrow passage and explore the burrow space above before he made a decision.

Since he was the captain of the Dark Demon-Hunter squad, no one opposed Grimm.
