Overall, the novel is very good and I look forward to seing it much higher in rankings. I didnt read novel here, so my input may not be as important as from others, but i still wanted to adress some points that fell to my eye:
1) Writing quality is very good, although here and there one can seldom notice errors, especially in sentences where multiples "entities" are getting referred to as "he". This usually makes sentence very hard to understand (which "he" is reffering to whom exactly), and it might be better to use "he" once and then later use name or something like "human", "boy", "warrior" or other description/synonym. Also in some cases sentence lacks (or has unneeded) negation. While context and common sense tells what is actually meant, it is very eye-catchy or confusing.
2) Not for me critise really, but including so much of previous chapter into begining of new one may drive away people on Webnovel as chapter price is directly linked to amount of characters, and as of late, every 10-20 chapters the repetitions will sum up to whole chapter worth of nothing. Sometimes such repetitions doesnt even make much sense from chapter-building perspective.
3) Power growth: introducing special manuals needed to advance to next major tier was a good thing, as it gives answers for future questions "why he is still at current tier?". But the speed of growth is too fast for prolonged story bulding in my current view. It was around 2 weeks real-world time and he outgrew everything he can in starting location: "school" and almost outgrew first continent. Unless he is hard-capped with new tier manuals, by the time he gets to academy he will be probably on level with professors. By the time they have first semester break he will outgrow everything and academy will become useless. Maybe even his whole planet will be far back. After all, most of his _current_ time is spent on advancing skills to legendary. But he is on his way to get there very quick (he can literally just order bunch of exp potions in auction house, having his nigh-unlimited funds, and get what he wants in 1 night). Even if he does not, number of skills he uses is very finite.
I like the novel, but it is in danger of what (I think) author of Dual Cultivation faced when he started one of his other novels — fast growing MC, full package, but after 220 chapter author understood that MC basically grew too strong too fast for his planned story. And so, he dropped it.
4) Some dialoges/interactions with "villains" are cringy, but its probably intented.
5) MC sometimes acts unreasonably stupid when he is close to women.
