Right now, regardless of right or wrong, Song Xiaodong and Chu Xianling could only grit their teeth and keep digging forward, as there was no way out behind them either. The snow they dug out from the front filled up the space behind them, leaving only enough room for the two of them to move.
The two of them now really resembled mice underground. Although the analogy is not flattering, it is indeed the case. Constantly burrowing, what could they be if not mice?
Like this, they labored tirelessly for over ten hours. Even Chu Xianling and Song Xiaodong were increasingly exhausted, and worst of all, they kept digging downward. If they weren't mistaken, it seemed they had gone the wrong direction.
"Whew! Let's take a break." Song Xiaodong dug a hole on the side and exhaled into it. The air inside the hole had become slightly thinner than before, so trying to minimize carbon dioxide emissions in their small space was very important.
