Not because he's like a genius in management. More so that he's the once-in-a-century Mozart that literally shocks the world with his ability to do crazy shit and the music empire is just kind of a side job.
It fits most points, I'm just missing a few chapters to start again since it's quite slow paced. Eh, mentor and he isn't particularly talented either. Doesnt seem bad, sadly very slow translation. Talent was given to him, isnt particularly well written either imo. Thanks tho.
* Do you really think that talent can be given? In the last 5 chapters, you'll know more about his heritage
I know how the story progresses. Still, Spoiler it takes a long time for his talent to recover, and a big part of that is played by his yet again randomly given part mentor, the willow deity. It's not a bad novel, but some parts unncecesarily drawn out and still fullfills quite a few cliches. Thanks, those I liked, except the korean one. It also has quite a large comedy part that I don't like, Toika or what he's called isn't an author that fits my taste. Maybe I could catch up on the other ones. Still, I remember the TL quality of GDN to be pretty bad, and the translator to be quite the prick. Well, whatever.
Spoiler: MG Martial god MC is biggest as he got something which even most powerful character at present doesn't have.His cheat is related to Divine Dao level characters.
Battle Frenzy And the other series by the same author, like Tempest of the Stellar War. Tempest has an mentor, but fufills the other parts of your requirements.
you were right about BTTH, and i also didn't like it. you were incorrect with PW tho. the supreme bone just made him the most talented in his generation. even without it, his talent was topnotch.
By the way do you know any world building without harem, it's hard to find those it's like the protagonist can't be strong there ain't a harem.
