This passage was noticeably wider than the others, and the walls on both sides were embedded with crystals that emitted a soft glow, illuminating the way ahead.

"The closer we get to the core, the denser the spiritual qi becomes. This is definitely not an ordinary underground structure," Su Wanqing said softly. She acutely captured the change in the air, lightly touching the crystal on the wall with her fingertips and feeling a faint wave of energy.
Chen Haotian gripped his sword tightly, his gaze scanning the surroundings vigilantly: "This spiritual qi is very strange; it seems to be mixed with some kind of unstable factor. Everyone be careful, trouble might be coming."
