It was an oval-shaped underground stone chamber.
Rather than calling it a stone room.
It was more like a huge stone basin buried in the soil.
The ceiling above the stone basin was almost corroded by various forces, but the materials around it and below were intact, not affected by the power of ashes at all.
In the middle of the stone basin.
Matthew saw something familiar. It was a stone pillar that soared into the sky!
The bottom of the stone pillar was flat and smooth, and the top had a bulge that looked like a huge mushroom. It was almost identical to the stone pillar that Matthew had seen in the Troll Underground Palace that stored the Evil Crown!
When Matthew stared at the stone pillar.
He could vaguely see the outline of a sharp sword in the stone pillar!
