The time period Uncle Sasuke had traveled to.
He had traveled to the time of the Uchiha Night of the Massacre.
With absolute, overwhelming force, he first forcibly subdued his teenage self, using that to force Itachi to deal with Obito.
Relying on the ocular power Natsuki had generously provided out of friendship, he single-handedly killed more than four hundred Root and Anbu members.
In the end, he even revealed a Susanoo dozens of meters tall and forcibly killed Shimura Danzō right before the Third Hokage, Sarutobi Hiruzen.
He also exposed Shimura Danzō's Sharingan arm before the other Ninja Clans.
With no other choice, the Third Hokage, Sarutobi Hiruzen, shifted the blame onto Shimura Danzō and made peace with the Uchiha Clan.
Uncle Sasuke did not use force against the rest of Konoha's people and instead accepted the Third Hokage's concession.
Upon returning to the clan, he was appointed an Uchiha Elder on account of being the Uchiha's strongest and for saving the Uchiha Clan.
Uncle Sasuke did not know how long he could remain in this time period. While placing Fugaku and Itachi under house arrest, he began gradually revealing certain events that would occur later.
Although Fugaku and Itachi had initially been only half-convinced, they still followed Uncle Sasuke in developing the Uchiha Clan and training new blood.
Uncle Sasuke personally trained his younger self and had him attend the Ninja Academy to get to know Naruto.

Sarutobi Hiruzen was forced to accept everything.
Over the next few years, the Uchiha began producing large numbers of powerful experts.
Sarutobi Hiruzen watched anxiously.
But Uncle Sasuke kept a low profile and remained stationed with the Uchiha Clan, never giving Obito or Black Zetsu any
