My Clones Go from One Piece to the Myriad Worlds

Don't touch Demon Slayer among the various genres; nobody watches it and it's disgusting.

Sure enough, no matter how powerful a multiverse expert is, they all have to serve as a lackey for the All-Knowing General when they arrive at the realm of One Person. If you don't dare to break the rules, why did you even bother writing about this world?

Nen users can also be killed by weapons, meaning there's a limit to Nen defense. As long as you have enough strength, you can kill. Also, Nen is Nen, and physical skills are individual physical skills. The protagonist is actually no weaker than an average Nen user. After activating Nen, fighting Hisoka is not difficult at all, given the information.

Even a brief introduction has typos 😅😅😅, which is...

The Eight Gates technique is overhyped. It's just high-damage pure physical attack; it might be a problem for ninjas in the native world, but it's practically nothing to the protagonist. They've made it sound invincible.

There aren't any major flaws, the only downsides are the average writing style and the author's apparent lack of familiarity with various anime and manga worlds, making it seem like the work is written by a novice reader.

Dude, what are you doing? Not only is the new world not aiming for a higher level, but you're turning it into a complete "Heaven Sword and Dragon Saber" story? The previous worlds were all anime, and now you're suddenly writing a low-level martial arts world? Didn't you realize how disjointed it was when you were writing it? Even a Resident Evil story with a virus would be better than this.

The more I watch the recent Bleach and Naruto worlds, the more awkward they feel; the more I write about them, the more something seems off.

Just a quick rant: some of the characters in the protagonist's writing are too heavily influenced by the author's subjective biases. While many authors enjoy portraying characters they dislike in a negative light to make it easier to kill them off, this kind of character development feels really awkward.

The protagonist is already very powerful; there's no need for him to recruit henchmen.
