I have an anxiety reading this, sure it is good but i feel like they are all not quite bright or smart. They been screaming non stop. I thought noise are one of the reason the zombie are attracted to ┑( ̄Д  ̄)┍
I am at chapter 8, idk if they are just stupid or what, they watch the video, they know about zombie things. They should have figured it out what happened and what that thing is. The author did not even make it zombies as a unknown creature.
Kinda a bit sad that yu seong disappear
