Sitting on the ground, he gnawed some moss to neutralize the surging stomach acid, and the discomfort in his stomach finally subsided a lot.
By this time, the weather had also completely darkened; pitch black surrounded him. Bi Fang decided not to look for another place and simply leaned against the rock to start pushing snow.

Especially since the ground beneath him was frozen, which was no easier to dig than ice blocks. The only advantage was that it was more likely to shatter, similar to brittle sugar cookies.
This permafrost in Greenland had been frozen for who knows how many years, like ice granules, a pity they were inedible—if eaten, they would cause diarrhea and easily block the intestines.
