Four dead at once?
If it wasn't Kai who did the killing, something must have happened inside the building!
Combined with the moist soil falling from the cracks at the top, Gu Ji couldn't help but think of the water covering the floor he saw in the underground fire control room these past two rounds.
One of the causes of a land subsidence is the extraction of underground fluid resources.
Such as oil, natural gas, underground water, and so on; in the 1920s, land subsidence was induced in urban areas of Hu Province, Jingzhou, and other places in the Xia Kingdom due to concentrated extraction of groundwater, and the North China Plain also experienced large scale ground subsidence due to the groundwater depression funnel.
Gu Ji could not yet determine the specific cause of this natural disaster.
If it really is related to fluids, then falling into a pit means there's a high chance of encountering groundwater flooding!
"Creak..."
