Before Traveling to Another World, the System Made Me Choose a Superpower

I transmigrated. Something calling itself the System told me that the zombie virus would break out on a massive scale in one hour. I was one of the lucky ones and could choose a special ability.

[Host, use your ability to survive the apocalypse alone and do your best.] [The truly cruel game begins now.] One hour until the zombie outbreak. I'm eating potato chips. The zombies break out. I use my ability. One hour until the zombie outbreak. I'm drinking cola. The zombies break out. I use my ability. One hour until the zombie outbreak. I start cracking sunflower seeds.

Looking at the broken front door he'd smashed open with his axe Me: "Shit." Him: "Shit." What do we do? We're probably doomed. Theme: What a twist of fate
