But the western regions already suffered from water shortages, so what was the solution?
These eighteen reservoirs, besides storing water for current use, could also collect floodwaters when the great flood eventually arrived. This was because Li Xiang and his team had not filled them completely, leaving them only about half full.
Then, at the locations of the eighteen reservoirs, Li Xiang constructed numerous channels elevated above the water level. These channels were useless for now, but when the torrential, unceasing rains of the coming summer arrived, they would serve to mitigate flooding by diverting the excess water into the reservoirs.
In the future, during the Apocalypse, when these "great reservoirs" froze over, the people of the Underground Cities in that region could harvest the ice for their needs.
It was a feat of divine craftsmanship, truly awe-inspiring.
