The cave walls are made of gray stone, the surface of which is incredibly smooth, lacking any sharp edges.
It seems like it has been meticulously polished over the ages, perhaps offering a fine and cool sensation to the touch.
However, in this seemingly ordinary cave, a faint crimson glow emerges from the depths.
This glow is so weak that it could easily be overlooked if not for careful attention.
Yet this seemingly insignificant glow, when it reflects on the smooth walls, creates a magical effect.
The originally monotonous, dark walls are instantly adorned with a mysterious and splendid color.
As if imbued with life, they shimmer with strange radiance.
This spectacle imparts to Lis a feeling of indescribable beauty, as if entering a dreamlike world.
Everything seems so unreal, yet so enticing.
Lis was not bewildered by this strange sight before him; he slowly took a step forward.
With that single step, he immediately felt a special change.
