@menomeno sorry that I have to tag you since you're the translator. It is "would have" and not "would of", look at the page 4. "If (
it is is supposed to be here ) not for me,
you'd of died in that incident". Therefore, it should be "IF IT'S NOT FOR ME, YOU'D HAVE DIED IN THAT INCIDENT"
It's a common mistakes that sadly happen everywhere, though I actually thought that logic is enough to tell that "would of and should of" are wrong.
edit: it's also in ch.15 p.8 too.
