An Unmanned Base

Selma Payne's POV:

A thick wooden door sealed the gate of the second base. No one answered, even after knocking for a long time.

We looked at each other and realized that something was not right.

"No matter what mission, we must leave someone to guard the base. This is an iron rule." Aldrich said, "With his rich experience, it's impossible that he didn't emphasize this to his subordinates."

At this moment, the tightly shut door seemed so strange, as if there was an unpredictable danger hiding behind the door, ready to give us a fatal blow.

However, it was almost dark now. We couldn't return to the first base or find a place to camp for the night. The wind and snow could easily kill us in our sleep.

Frank's expression was grave. No one knew what he was thinking.

In the end, he decided. "We have to force our way through the door. It's going to be dark soon. We can't wait any longer."
