Zombies Everywhere

The protagonist's account:

You wouldn't believe it, but I was just dozing off in class. When I woke up, the whole school had changed.

The classroom was nearly empty, and strange roars echoed from the hallway, getting closer and closer. I remember our class's front and back doors got broken by Xiong yesterday, so they wouldn't lock. We only decided this morning to have Grandpa Niu the school janitor fix them, so what should I use to barricade the doors now?

Note: This short story takes place in parallel world Z26748 of the main DC universe. It has little effect on the main story, and if you don't know what's going on and feel confused, you can just read it as a standalone story.

P.S. This story is expected to start updating at the end of September. It has only four chapters, updates monthly, and is expected to be completed by the end of the year.
