Weilan Tian gradually calmed down and got up from the ground. He looked around and found the entrance that was blocked by a curtain of water behind him. More precisely, the water was blocked by an invisible wall, preventing it from entering the cave.
This scene startled him for a moment.
"This should be under the river?" Weilan Tian muttered to himself in doubt and reached his hand out to touch the water wall. He then discovered that his hand could penetrate it with no problem, which meant he could leave here if he wished. Perhaps he floated along with the current and accidentally arrived here.
Since the retreat route wasn't blocked, Weilan Tian decided to check this cave out. He used his Spiritual Sense to probe the dark path ahead and found nothing suspicious except a plain and cold passage.
Without thinking further, he took a step forward, walking along the path cautiously.
