"This is..."
The exit soon appeared, but when Lin Xuan looked at the scene before him, he was dumbstruck. Though he was widely experienced, this was a sight he had not only never seen before—he had never even heard of it.

It was not small. Lin Xuan made a rough estimate and figured it was probably over a hundred mu in size, with magma surging and roaring inside it.

Of course, Lin Xuan did not have this problem.
His cultivation had already reached late-stage Spirit Division, and the purity and density of his magic power far surpassed cultivators of the same rank. Although the high temperature here was enough to leave one tongue-tied, there was not the slightest hint of discomfort on Lin Xuan's face.
