Ji Xinghuo walked up to Ren Mian, and a sight of wonder came into view.
This was a massive underground space, covered by countless plants—roots, vines, and branches that intertwined with the ruins of buildings that had long since been abandoned.
Roots and vines dangled from above, and the ground was covered in a jungle so dense and thriving it could rival the primeval forests on the surface.
Among them were many luminescent plants.
They emitted a dim light, revealing traces of civilization; it was clear that this place had been carved out by human hands. The dome was approximately three hundred meters above the ground, supported every few hundred meters by colossal square crystal columns that extended for kilometers.
"A city of the Crystal Elite Clan?" Ji Xinghuo asked.
"Correct."
Ren Mian nodded slightly, "Long ago, it was an underground city of the Crystal Elite Clan, but it was later conquered and turned into a breeding chamber for the genetic mother tree."
