The day the apocalypse arrived, I was in my dorm room, reading a novel in bed.
My roommate burst through the door and lunged at me, trying to bite me.
I was so scared I shut my eyes, but a cold electronic voice rang out in my mind:
"Host detected. Binding to Room 306, Building 7, South Campus, successful. Current safe area: 18 square meters."
The doors and windows were indestructible, and the water and electricity would never run out. Thanks to those 18 square meters, I survived the zombies.
Later, I discovered that every area I cleared made my "territory" expand by an inch.
A dorm room, a floor, a building, a cafeteria, a library...
While survivors outside were killing one another over half a bottle of water, I had already mapped the entire university.
They said there was no safe haven in the apocalypse.
That is, until they saw a girl standing in the middle of the brilliantly lit campus.
She wasn't called a queen or a leader.
The whole school called her the Principal.
