From these two aspects, it can be confirmed that before the disaster, the water quality of Dragon Lake was very poor and definitely did not meet the standard for direct drinking.
But now, not to mention that the water of Dragon Lake had dried up during the disaster, the current water is all new.
Even if it was just as poor in quality as before, the survivors wouldn't be too concerned; after all, when they are about to die of thirst, who cares about the health quality of the water? As long as it quenches thirst, that's enough.
This is also why the camp where grandpa was located, after the city was destroyed by the earthquake, decided to move the survivors over here to set up camp.
Although the roads were somewhat rugged, it wasn't much of an issue for the Black Car with its powerful off-road capabilities. It didn't take long for Dong Tianyu to use Divine Sense to find the camp here.
