I Didn't Become Hokage, so I Had No Choice but to Unify the Ninja World.

Traveling through the Uchiha clan will inevitably send red flags throughout the ninja world. Under the guidance of Uchiha Yurin, the godfather of entertainment Jiraiya was born, the mechanical ascension Hiroyuki, the scientific madman Obishimaru, the medical expert Tsunade Hime, the blasting genius Deidara, the emotional lecturer Terumi Mei, the mountain to save his mother Zetsuko... Of course, the new ninja world doesn't have enough food to feed the old guys. Hiruzen Sarutobi, Danzo Shimura, you old guys, please spend some gold coins. (Slow heat, no spoilers, no character breakdown, single female protagonist, farming)
