Since all three were equipped with exoskeletons, even though their excavation tools were just simple shovels and hoes, they easily dug through the snow.
The passage that Chen Xin and Qin Lan had dug out last time did not become completely buried, although the newly fallen snow later sealed its entrance, traces of the passage still remained.
And as Chen Xin, Qin Lan, and Mo Qingyan excavated the snow together, the passage that had been dug out last time was revealed again.
"It seems that after it was dug out last time, the area froze over, so even though it was buried again, the ice walls remained," Chen Xin tapped the ice wall of the passage, quickly understanding why the passage persisted.
Mo Qingyan looked at the passage curiously and asked Qin Lan, "Did you and A Xin dig this when you came last time?"
