Chapitre 451: Chapter 451: [Heavenly Sword Immortal's Manual]!

Tang Li Xue took out a mid-tier spirit stone from her space pouch and used it to illuminate her way since all mid-tier spirit stones were emitting a faint light.

The light from the mid-tier spirit stone was too dim, so it was far from enough from illuminating the way in front of Tang Li Xue like a flashlight, but she could still see everything clearly with her fox eyes.

There were countless ancient-looking murals carved on the entire cave's right and left walls, ceiling, and even the floor. 

Tang Li Xue explored the dark cave for a few hours, but she still failed to find any clues on how to complete this last trial.

Tang Li Xue only kept walking forward from the beginning until now in this few hours, but she still could not see the end of the cave.

"This cave is really strange... Why does it seem that I only walk in the circle all this time?" Tang Li Xue murmured and frowned deeply while pondering her next moves for a while.
