National Survival: Behind Me Is the Country

The entire planet has been pulled into the survival world, and the eyes of monsters outside the wooden house are staring at you. It can be called a national survival nightmare version, but unfortunately, everyone is different. Standing behind me is one of the great Blue Star nations. It's too low to start by staying in a shelter for three days at the beginning. If something happens, of course you should first ask the police for help. No, officer, you have to believe me, I'm really not mentally ill.
