The bitter cold continuously emanated from the narrow cave.
To venture into this cave, with his current equipment, he would probably be unable to explore comfortably.
Just the chill wafting from inside was enough to make Xu Xin shiver at the entrance. The temperature inside must be below minus fifty degrees, and possibly far below that.
He glanced at the time; it had only been over half an hour since he began climbing. He still had plenty of time before the twelve-hour deadline given for the task.
And he had already climbed over three hundred meters.
No surprise, as this twelve-hour limit was meant for ordinary survivors. Today, he had arm strength enhancement, so his climbing speed was far faster than that of ordinary survivors.
With ample time, he could pause his climb to rest and explore along the way.
"Crack..." Another faint sound echoed.
This time, because he was at the entrance, and the sound came from inside the cave, Xu Xin heard it clearly.
