Gamemode Unlocked?

There was a bunch of zombies and monsters that were mutated."This didn't happen before" I thought . But just in time the system popped up a warning that said

| things will progress much more faster than before|

"What" I yelled loudly in my head. I ran back into the building but a few zombie followed me which I killed before it could bite me. They were kinda hard to kill. I got the rewards which was 3 teeth, a medium sized dark gem which was really precious and i also got 2 coins. I didn't think that it was worth it.

I cooked some instant ramen that was in my pantry. My water wasn't working which I kinda predicted so I used bottle water. My stove was still working which was impressive. Although my fridge wasn't working but since there was nothing inside, it was fine.

Then a quest popped up. A quest I said. I decide to check what it was since it was the first quest I had gotten since I came back to the past.
