The Entire Clan Defects to Iwagakure, and Konoha's F4 Lose Their Cool

[Hokage fan fiction + System + fiery battles + invincible power fantasy + farming and development + more children, more blessings]

After transmigrating into the Hokage world, Xuan Ye becomes a member of the Uchiha Clan.

With the clan on the brink of disaster at the hands of Konoha's F4, Xuan Ye binds himself to the “Strongest Clan-Building System” and gets dual Kamui from the start!

The more prosperous his clan becomes and the more members it has, the stronger he gets!

Konoha looks down on us Uchiha? Danzo wants to gouge out our eyes?

Xuan Ye sneers and turns to leave. “If Konoha has no place for us, then we're done serving them!”

He leads Uchiha Fugaku, Obito, Shisui, Itachi, and a host of other geniuses in packing up and fleeing overnight, taking the entire clan to join Iwagakure!

Danzo sends Root after them? Dual Kamui will teach him a lesson!

Kumogakure and Sunagakure want to take advantage of us? The Uchiha powerhouse squad will crush them all!

For the sake of his clan's prosperity, Xuan Ye leads by example, marrying beauties from across the shinobi world, having children like crazy, and investing heavily in infrastructure and agriculture!

Years later, when Xuan Ye Uchiha arrives at Konoha with tens of thousands of Uchiha wielding the Mangekyō Sharingan,

the shinobi world is left stunned!

Xuan Ye looks down at Konoha's trembling F4. “This time, I'm taking back everything that belongs to the Uchiha! Konoha's F4, prepare to die!”
