"Du Peng is back."
"Open the shelter doors and let Du Peng and the others in."
A few people walked into a spacious cave, with four extremely heavy doors at the very front. The doors bore many scratches from monsters. Clearly, this place had also suffered monster attacks over many nights in the past.
But the monsters couldn't break through these sturdy steel doors. After all, this was once a military fortress, and such a door could even withstand missile attacks.
As one of the doors slowly opened.
A passage appeared before them.
The passage was dimly lit with a yellowish glow, the air was stale, filled with a sour stench. There were too many survivors living here, exceeding the shelter's capacity, so the living environment wasn't very good.
But at least it was relatively safe, without the worry of biochemical monsters invading.
