ideas for books

Naruto at some point before becoming genin(i am still unsure if this will be just before graduation, since naruto's birth, or at any point in the middle), will die and the tenno will take over their body, the indifference beeing responsible for putting mc there due to a deal

Mc would had successfully brought peace to his universe, but like with the fall of the orokin, mc just coulden't embrace life as a civilian. He was about to(for the second time) put himself in cryosleep until the universe needed him again, but wally offered an alternative: traveling to another universe, one that is doomed to end without mc's help

.

Mc will have all of naruto's memories(well, that if i decide to make mc transmigrate as naruto at any point older then a baby), he will also know how to build his weapons from the game(one of the first things he will do once he becomes naruto, is to ask the hokage for a forge), mc won't give firearms and stuff to others(he will even put a safety lock on everything that can only be opened by void energy, so no one can use his weapons but him)

I may have mc get a puppet like the ones from suna/sand village to use as a warframe, but i am still on the fence
