Zombie Apocalypse Start Acquisition System

Sorry guys, I accidentally reposted the first one.

The author can put the explanation before the first chapter. To me, the author's writing is not very good. Does the author want to write the cause of this work (why mutates into zombies, zombies) and the identity of the protagonist later? Moreover, the first few chapters are not very clear (not the content) about where the protagonist is, how to save people (why you need to save someone you don't know, if you know me, I didn't say anything), and what the protagonist is going to do (what is the purpose). I won't say goodbye until I go to bed.
