The lake water poured back into the Underground Palace, but was ultimately blocked in the passageway by another layer of formations.
Two figures gradually emerged on the formation's light curtain. Lin Bai and Tuo Baxin passed through the formation and entered this dim Underground Palace, where the sun and moon had never been seen for years.
The passageway was built of stone bricks, with Night-Luminescent Pearls embedded in both sides.
Whether the Demon Race had done it intentionally or not, the light from those Night-Luminescent Pearls was dim. The road ahead remained shrouded in darkness so thick that one could not see one's own hand before one's face.
Fortunately, both Lin Bai and Tuo Baxin had cultivated the Mystic Eye Technique. Seeing through the darkness was no difficult task for them, and they carefully pressed onward.
The formations within the Underground Palace were no inferior to those outside. Layer upon layer was stacked together, forming an impenetrable web. If it had been anyone else, the formations would have given them a splitting headache long ago, but they could not stop Lin Bai and Tuo Baxin.
"Although there are quite a few formations here, they don't seem to be very powerful." After passing through several formations, Tuo Baxin's expression grew increasingly strange.

Tuo Baxin furrowed his brow, somewhat unable to understand.
Lin Bai gazed deeply into the darkness
