The cave looked ordinary on the outside, but it was pitch black inside. Lin Bai frowned and sent his spiritual sense in, but there was no reaction.
There seemed to be no spiritual energy fluctuation inside, as if there was no danger. However, Lin Bai felt as if something was calling him. There was a faint voice telling him that he had to go in.
While Lin Bai was observing, he didn't notice a gray fog floating out of his body, as if it had been summoned by something and entered the bottomless hole.
Lin Bai's pupils were slightly startled, but he didn't notice that there was also a gray fog surging in the depths of his vision. It was as if his eyes were covered by a pair of invisible hands, and his pupils were gradually covered with a layer of darkness, making Lin Bai have the urge to step into the hole.
