Zero to hero? More like zero to infinite propaganda. Every character started to say 'outside nine provinces everyone is barbarian', like dude calm down why do you hate other countries so much and you're writing something like that in a book? If this book was written in another country I'm pretty sure that author would be banned for racism and xenophobia. Probably someone tried to machine translate and edit it with notepad's 'find and replace' but forgot to replace some words so every now and then realms and everything starts to become confusing. MC's character is really awful as well, literally beats 7 year old little girl and amputees her so he can test his abilities on her. If you're into dark/evil mc then it's alright but then he starts saving random people.
