that means nothing at all, post the chinese name of the fanfic.

haki is the manifestation of one's will and ambition, not directly related to soul at all, soul makes dead people alive and live people have goal and ambition, based on ambition and effort haki is nurtured. so having a strong soul and strong body increases the higher limit of haki but someone weak but ambitious can have haki too.

that's three abilities though. there's nothing in common between analysis and copy, and copy itself is an overpowered multiple abilities in one. it's the difference between blueprint and manufacturing of item, and manufacturing involves materials, processing & assembly.

giving it 5 to skew the baseless reviews about MC being beta and spineless. MC is stupid, irrational, trigger-happy, petty, extremely vengeful and hyperactive but he is not beta. everywhere he goes makes the situation bad and then worse, he is morally bankrupt too after an incident.

had ace not eaten mera mera no mi, he would've become stronger. he could've easily become second roger, but instead had to spend time developing a fruit powers instead of his physical and haki prowess.

Brother, people have killed for wands with any links to elder wand and oliver himself is one of those searchers. It's a canon plot point. you can't insert items contradictory to canon in fanfic, just removers all immersion immediately.

just my two cents, if you want to write a one piece fanfic, explore the unknown fruits that can be overpowered by creativity and user themselves or simply discard devil fruits and focus on haki, science and physical developments. using crossover powers like mana, chakra and qi are cringe too.

good as a comedy but MC becomes braindead from an intelligent Shinigami after 50 or so chapters to achieve this. literally MC forgets the plot and forgets he is supposed to know this as a reincarnator.

I stopped reading here but just fyi Author doesn't know that garp has Conqurerors haki and that swordsmanship require phsyique developed for the swordsmanship more than the knowledge of a particular cut. in the world of swordsmanship having the physiques developed for sheathing and unsheating swords faster is the talent for swordsmanship.

can confirm that author isn't even aware that garp has conqueror's haki. also physical strength is a necessity to become a top swordsman.
