Tanaka wishes he had a gun rn

Maybe, seems like it's the only one they can still use after being crippled so it makes sense to use it

So basically, it's not tattooed on his chest, it's written on his shirt (I assume) because this is a term of speech. Basicaly, he most likely has this character "獄" pronounced yù on his chest. Though he could also have "監獄" which is Jiānyù

It's still basically refining humans, so yeah, still evil. Kinda like how anti-heroes are technically evil but they're doing good work

Sorry if that offended you, but it also doesn't give you and everyone else permission to complain about literally everything under the sun because you can't just f*cking enjoy it without being rude about it.

Maybe cause the bad person had the martial arts manual? I mean, there's also a lot of plots where a good person dies, and a bunch of people attack their old residence to find their "legendary" martial arts. It's maybe because, oh idk, they store their martial arts at home kinda like you might do any other kind of book so it doesn't get like.. damaged or stolen.

It's black, just a mistranslation

You do realize that talent is in different areas right? Someone might be able to easily comprehend math and utilize it in all sorts of ways like its an art, while the exact same person might not even be able to memorize the periodic table because they don't really have an affinity for it. Just cause he has heavenly comprehension doesn't mean he's smart enough to see if something's fake, especially if he doesn't even have the knowledge.

Tell me where to find the story please

That's actually used a lot of the time with these forces. It's mainly used in lower tier martial arts worlds where skin, muscle, bone, organ, etc.. is actually powerful rather than just entry level so we have these forces which are basically prerequisites as the world is so weak that they don't have the ability to just refine just like that, they have to develop extremely high control over their bodies that form these forces that then can be used to refine their bodies.
