Noland Lee did not rush to leave the warehouse, he suddenly thought of something...

How did the greenhouse attached to the Fissure Corridor occur? Why is it present within the Pollution Zone?

Noland Lee was certain that before the Pollution Zone appeared, there was no greenhouse for cultivating Artificial Angels in the Fissure Corridor.

Because the place where the greenhouse was located corresponds to layers 30 to 60 of Sector 6 underground. Noland Lee had previously explored this area, and there was no greenhouse.

So, there is only one answer...

The Pollution Zone is extraterrestrial space pollution that has been remodeled to imitate the universe he resides in.
