Yup, makes him seem like an absolute psycho.

Please decide on a moral compass for the mc, either he is a more or less sane person who usually protects the innocent, heals the wounded and kills the "villains" which has been consistently shown through the whole fic or he doesn't have any issue with the Kid pirates going on a indiscriminate murder spree as you described in this chapter, you can't have both.

I am confused, what's the point of the Hercules' method? One piece characters can train to achieve the same results anyways no?

Webnovel keeps deleting my spacing, so chuck it, I will leave it as is, just know that it wasn't me that wrote it as a god damned wall of text...

The start is great, interesting characterization, plot slowly deviating from canon and etc. But by chapter 70 or so the story gets weird, as if the author writes about what is in his head and not what he wrote. Like, Paul fucked up two times and even then, the first time wasn't a 100% fuck up of his since he didn't actually do anything and it was prevented before any harm was done but everyone started pretending like fucks up ALL the time and the author JUST.KEEPS.HAMMERING at the reader with it, in 7 years, two fuck ups, that's it, sure major fuck ups but that's not exactly what I would call a pattern... Contrived drama and characters constantly going off the deep edge in really cringy ways, feels like I am reading soap opera. Relatively minor but a good example of why I felt that the story was becoming really schizophrenic is Rudeus fighting with Sauros cause Sauros attacked him out of the blue and during the fight Rudeus starts ranting how Sauros "is a tyrant who doesn't understand the plight of the common people" the hell?! What insane logic led him from Sauros throwing a punch at a kid to him being "tyrant who doesn't understand the plight of the common people". Don't get me started on "bringing Sylphie to meet Eris cause she is my best friend and they need to meet" what the hell kind of inane logic is that? Either the author stops making Rudy as dense as the average harem protag and admit that Sylphie is in love with him and then that would make some kind of sense or this is just deranged logic, who the bloody hell brings their childhood friend who has totally only platonic feelings for him for the first meeting with the fiance, in what clown world would that make sense?! The fact that there was a lot of drama around Sylphie and the Mc being unable to marry anymore even though Paul SPECIFICALLY asked if the arranged marriage would block him from marrying anyone else and was TOLD that THERE IS NO ISSUE. The crazy turn about with Rudy, there was little sign of his "temper" and suddenly EVERYONE keeps on ranting how volatile he is and he starts talking like a blood thirsty psychopath.

The mc's insecurities are kinda cute, you convey really well the weird mix of adult and child due to him losing most of his memories but retaining the various traumas he brought with him from his previous life.

You keep writing stuff like "adopting a faint smile" why? It's so ugly! Why not just "smiling faintly"?!

The writing is great but the rest... The mc is a cringy Garry Stu, he can do everything, he is very observant, very nice, very talented, very smart, strong, the author barely bothers to even excuse the power up rainfall (like seriously, getting from a scrawny kid to a buff adult in a day via training and diluted potions?! A magic, two developmental skills and a skill from the moment he got his falna just because?), everyone likes him despite the conversations feeling wooden, it's enough for the mc to say something like "Ur very purty" to a girl and that's it, she is all already a blushing mess sighing how dreamy he is with little to no attention paid to circumstances and backstory and etc. And on the other hand there is a feeling of bloat to most chapters, a lot of the text is spent inside the mc's head with little to nothing happening or conversations where another character gushes how great he is. In short, the glaring issues are that the author should have held back with how super special awesome the mc is and worked on conversations some more, not every conversations has to be a variation of the mc cornily flirting or impressing someone, especially when EVERYONE are so receptive of the corny flirting...
