As they walked not far down the path, a cave entrance appeared before everyone.
Upon entering, they found a staircase leading downwards.
After descending the stairs, the scenery before them changed dramatically.
The original mottled cave walls gradually turned into orderly stone walls, eventually becoming walls built with neatly stacked bricks.
"Why are there brick walls underground?"
"Could it be an illusion?"
The Heroes began to whisper among themselves.
Henry tapped the wall with his sword. Sparks flew.
These walls were no illusions but a tangible reality.
The group continued forward.
Over time, the stone walls started to show the signs of aging.
The deeper they went, the more dull the color of the walls became.
It was as if the same stretch of wall was constructed in different epochs.
Lamps began to appear ahead, and the stone walls finally reached an end.
