章節 737: Chapter 458: Mysterious NPC, This Charcter Is Too Old [3/3]

Richard became even more motivated to lead the way toward meeting the sixth high school NPC.

A 20-meter-tall and 30-meter-wide passage on the right side of the valley led directly into the mountain.

The Soul Eater Crows and the Dark Servants had already entered the depths to scout the way, so they were not afraid of sudden danger.

They gradually tilted down after about 200 meters into the cave. Richard's sight suddenly widened following another 100 meters of a walk.

That was a vast oval underground space.

The height was about thirty meters and directly exceeded a thousand meters.

Hundreds of giant stone pillars supported the underground space.

Each stone pillar has hollow in half. That was surprising.

Hollows and steel cages filled the area.

They looked around and found several steel cages with white bones long since weathered away. It was obvious that they had been imprisoned and died.
