What to learn? Everything -.- Even as genius this doesn't make sense, especially since he's just starting out. I mean he's now learning water, earth, lightning, wind and medical ninjitsu. Fuinjutsu, kenjutsu, taijutsu and genjutsu. Those at least. Fuinjutsu and medical ninjitsu being especially hard.
The Senju clan means a clan of a thousand skills, thats why they were feared, not because of Hashirama’s wood release. MC is not good at everything from a young age, he is starting out now rather than later, especially since he has massive chakra and can use shadow clones and have the right people to teach him. He has Tsunade to learn medical ninjutsu, btw he learned the medical theory while growing up. He has Kushina for Fuinjutsu, he is Uzumaki. He has Shisui for Kenjutsu, he has Might Guy for Taijutsu, and hes Senju so he has a lot of ninjutsu and genjutsu to learn from. And btw hes not super overpowered, people need to remember Kakashi was a beast when he was my MCs age. My MC just has a larger arsenal.
