When I woke up, I was exhausted, the smell of blood filled my nostrils, and I felt uncomfortable all over. I walked to the floor-to-ceiling windows and opened the curtains. What I saw was a residual scene. I didn't know what happened. It was like biological zombies attacking the city. Everything was no longer the same as before.
The end is coming, how to return to the original world.
[Actually, it's a zombie article QAQ]
