"You can actually identify the flowers and plants here?" I asked. The underground space before us was enormous, stretching as wide as more than a hundred football fields. However, the vegetation here was so luxuriant that the other colors in the space seemed too sparse, making the place appear narrow.
This place was not limited to vegetation, either. Strange flying birds, beasts, and other creatures were everywhere. Of course, they did not look particularly vicious. At most, they were part of this region's ecosystem. After all, even immortals knew how to bring a place to life instead of leaving out one essential link and allowing the whole thing to wither away.
So there were not only trees here, but underground rivers as well. Of course, these underground rivers must have been circulating within this enclosed space. Otherwise, if they had connected to rivers outside, this region would probably have vanished long ago.

Their value is terrifying enough without even needing to say more." As Song Ruo followed me down, she spoke of the surrounding plants as if she were recounting family treasures.
"You really do know everything under heaven and earth.
