It was winter in China. Above ground was plagued with a chilly breeze and a lack of street-dwellers.
As the crisis slowly approached, most people rather stayed at home, huddling together to stay warm instead of going outside and invite troubles.
Tourism was heavily impacted by this lack of interest. Most of the famous places such as well-known mountains and rivers had reduced tourists.
However, a thousand or so meters underground, the rats were thriving economically.
That provided a sharp contrast against the desolation that was observed above ground.
It was as if the Greater Rats were not worried about the lunar disaster at all.
They lived in the subterranean strata and protected by the strong and steady rock layers. Even if the above ground had all been flooded, the seawater would not make its way underground, stopping at the aquifer.
