Well, it's pretty good, but there are some mistakes.
-Timeline is a mess,
-Sharingan doesn't come from Otsutsuki, but from shinju, as is the sage body and wood-style, from Kaguya side u get dead bone pulse and byakugan.
Hagaromo inherited it the same way Naruto his whiskers,
-In Naruto world chakra is more soul thing than body, ofc body is influencing it, but u can say that Yamato isn't Hashirama, even if he has DNA of Hashirama, which for me seems like his chakra isn't that attuned to wood as was Hashiramas(someone is gonna say something about Madara, but he is a transmigration of Indra direct son on Hagoromo). Orochimaru even after switching bodies still has his immense chakra and the same affinity(wind), and lastly, Edo Tensei, which literally forces soul in somebody body, changes them to look the same as they were before they died and having the same bloodline, if the body was the source of these things, the undead ninjas wouldn't have the same bloodline.
Besides these points, this novel is pretty good, most people would not care about these things, but I really don't like when someone is putting the same knowledge as in our world in a world where it's clearly different, I don't see any chakra in our world, so the worlds clearly differ in a way. If it was that 'easy' to get fully activated bloodline as activating genes, then Orochimaru would be god be the time of chunin exams.
If i made some mistakes fell free to point it to me :)
