Surviving in the Sky: Starting with a Divine Sign-In System

Survival in the Ocean is over Survival in the Caves, Survival in the Caves is over Survival in the Sky

Why does the male protagonist, a mercenary who can't cook, take that woman in directly? Why does a mercenary trust someone directly? Why?

How can Sky survive? No supplies, okay? As for the caves, it's easy to say because no one knows what's down there. As for the sea, I can wander around, catch fish, eat, and even come across islands, but I still don't understand the sky.

I don't understand why it takes ten bottles of water to exchange for fifteen metals when three bottles of water can be exchanged.

Cerebral palsy only has a few tickets, but it only accepts a girl. If you don't have a girl, you will die. What's the point of comparing things?

Did the author forget what he wrote? Didn't he say that because he obtained the drawings, the supplies were doubled on the first day? Doubling the odd number is also impressive.

I really don't know why I accepted that girl. How many words are there?

Have a look at your profile? The earth is torn apart, the ocean is churning, and humans need to survive in the sky. You have a passenger plane, where do you stop? Or is it that passenger planes have unlimited fuel and can fly in the sky all the time?

It's really poisonous to sign in for whatever you need.

You are really not afraid of being stabbed in the back while sleeping, right? Just by meeting a girl you have never seen before, you know that this person is a good person??
