"The snow's getting even heavier." Ren Xiaosu sighed as he observed the weather.

"It's said that it was even colder than this right after The Cataclysm occurred." Li Qingzheng was panting as he trudged through the snow. "Some of the older people said they had to store enough food to last them the entire winter during those years. If there wasn't enough food, they would even resort to stocking up with tree roots. No one could go outside in the winter at all."

This heavy snowfall came so fast and unexpectedly that the Divine Arms officer even started to waver on whether they should continue marching. When he looked at his GPS device and saw it was still functioning normally, he felt a little reassured.
