Alchemist

Since when does Spider-Man act like that? Being a devout Christian is more Daredevil's thing.

And just like that the story got ruined. Not only did you not warn people that this is a crossover with other franchises, but you gave the MC a system that can easily make him completely overpowered for the setting, despite the the fact that as the former vice-captain of the Rocks pirates, he should already be one of the strongest people in One Piece...

I'm kinda disappointed that he visibly became younger. I would've preferred a protagonist who's a badass old man.

Byakurai seems way too weak. It may be a low level Hado, but it should still do a lot more damage than just slightly shocking people. I'm also not a fan of giving the protagonist out-of-context powers that don't fit into the power system of the world. The author could've at least adapted the rewards to better fit into the Naruto world.

Unfortunately, it seems like the fic is becoming more of a xianxia novel as it goes on. Now, instead of just training, Kakashi is going into seclusion to break through. Is he trying to reach the golden core realm or something?

The weirdest part to me is that xianxia novels tend to have spirit veins or something like that, which are basically the same thing, but because dragon vein has 'dragon' in the name, it clearly has to be an actual dragon...

Why do Chinese authors insist on mixing wuxia/xianxia elements into stories based on manga/anime? Having the Dragon Vein Chakra take the form of an actual dragon, just because it has dragon in its name is so incredibly stupid, it's almost enough to make me drop this fic. I hope this doesn't get mentioned again, or I'll actually have to stop reading this story.

Honestly, the Future Sights should've hit and taken out Rhyperior. Having Gary constantly win without even losing a single Pokémon is getting pretty boring.

Looks like you skipped a chapter or two...

Thanks for the warning, this kind of story definitely isn't for me then.
