Perhaps to prevent collapses, the walls of the entire underground city were covered with the same reinforced material as the airship's armor.
Countless lighting fixtures were embedded in the ceiling, illuminating the entire underground space.
The buildings were generally white on the outside as well.
This was probably to keep the residents from paying too much attention to the fact that they were actually living underground, where the sun never reached.
Luo Zhen could see considerable Spiritual Energy lingering throughout the underground city, proving that the people here were living quite well.
However, he did not know why these people were living here in the first place.
Although the environment here seemed to have been developed to a certain extent, an underground residence could never be considered comfortable or pleasant. Food shortages were frequent, and a lack of sunlight could easily cause endocrine disorders and the like. This underground city was destined to be unsuitable for long-term habitation, so most of those living here had probably been forced into it.
If that was the case, why were the people here living underground?

Ripa explained.
"However, after the Jes faction began to emerge and the existence of the Humanoid Demon Scarabs became known, this place became a shelter for people headed by His Holiness the Pontiff."
Hearing this, Luo Zhen understood somewhat.
Just as Jes regarded the Pontiff as an obstacle to his domination and was determined to eliminate him, there were certainly many others among the human race whom Jes viewed as thorns
