Wei Bai's explanation to the others was very clear and simple.
He had basically reached an agreement with the Yuan Family.
The Yuan Family disagreed with mining near the center of the city because they were aware of their own technology and couldn't ensure it wouldn't affect the city.
Even if the impact from falling debris during mining could be avoided, mining on the dome would greatly affect the air quality in the main district.
After all, this is the underground world. Although the air circulates, it moves very slowly. Once polluted, it would be hard to self-clean.
Not to mention long-term mining sites, spreading pollution from above downward.
"...I never really considered this." Xu Ying shrugged slightly.
If her plan went smoothly, she could soon lead humanity from the underground world back to the surface to reconstruct sunlight.
Whether the underground base was polluted or not, it truly didn't matter.
