S-rank Dungeon—Xarath's Womb.
This dungeon was one of the strangest dungeons everyone ever saw.
It was red-bordered yesterday when they decided to enter in today's evening, but it had turned gold-bordered two hours ago before everyone had arrived at the location.
The dungeon structure seemed to be a living entity, and everyone was in that semi-alive biological place with caverns, strange fleshy monsters with neo-glowing colors from their internals, liquid pools, and pathways.
The monsters were highly corrosive and had unpredictability to their powers, with most of them having self-explosion upon their death that would deal potent corrosive and acid damage.
Fortunately, the number of total old monsters in the group was four, including Admiral Rudra, along with eight other frontline Adventurers.
