"Wow…" Xue Yan unconsciously let out a light gasp of admiration.
They had just walked into the hall and began to take the sights into their eyes and from Xue Yan's reaction, it was easy to see that the place was quite impressive.
Similar to the main area of the 10th floor, this entire place was a huge cavern system equipped with not just its own flora and fauna but also sunlight. Yes, sunlight! It was quite surprising to discover sunlight within a cavern located deep inside Black Grill's Mountain[1]. It wasn't that there was a hole made on the cavern's roof, letting in sunlight, instead there was a real sun located high above! The cavern's roofs were so high up that not only was there a sun but there were also clouds floating in the atmosphere.
