Meanwhile, Zhao Ya noticed that the air here was fresh, and from time to time, a damp breeze blew through, indicating that there must be a connection to the outside.
Before long, they arrived at a spacious stone hall, but the smell here was far from pleasant, as the air was filled with a pungent and foul odor.
Looking down, the ground was covered with whitish-gray droppings.
"This is...," Nie Jingnian was about to speak.
Zhao Ya raised a finger to signal him to be silent, then pointed upwards.
Nie Jingnian looked up, only to see that the stone dome above their heads was densely packed with bats.
In the light, the eyes of these bats glowed red, and when clustered together, it was as if a red carpet had been laid over the stone wall.
The sight made Nie Jingnian's scalp tingle.
These bats obviously had undergone transformation as well, and though each one was small, their numbers were overwhelming.
Nie Jingnian gathered his spirits and slowly followed Zhao Ya further in.
