Battle in the Auction House

The room was wide, and the air inside was tight. There's neither a window nor a path for the air to enter deep inside this place, so ordinary people below C-rank would suffer suffocation from this plane. The room was illuminated by a magic crystal hanging on the walls. Without this magic crystal, the entire place would be dark.

Souta's group was standing in front of the door frame. The door, which was made of rare materials, was on the floor just beside them. It seems that the people inside the room forcefully opened it.

The whole place didn't collapse even after S-rank powerhouses fought in this place.

It feels like Souta was inside a high-level dungeon in the Imperium. The dungeon in Imperium was durable, as it could handle the power of powerful monsters. Just looked back when he subdued the White Jade Spider in the Forest of Eternal Light. The White Jade Spider was a third evolution stage monster, yet the room that it resided in didn't even collapse.
