Naruto's Warring States Era: My Chakra Industrial Empire

Also known as [Naruto: Total Industrialization! I Bombard the Clans!]

An engineering student transmigrates to the Warring States period of the Naruto world and becomes the son of a minor ninja clan leader whom even the lowest-ranked ninja look down on.

The clan is so poor they have to keep sharpening the same kunai. Their land is barren, and powerful neighboring clans bully and extort them year after year. Just as panic grips the entire clan, Kitahara Che awakens the [Ninjutsu Industrialization System].

While others toil to master chakra and throw fireballs, he researches chakra steam engines, opens assembly-line factories for ninja tools, and mass-produces exploding tags and rapid-fire shuriken. While others inherit ninjutsu through their bloodlines, he establishes a ninjutsu research institute, improves low-level techniques, and develops chakra cannons and defensive barrier towers.

He builds roads, digs canals, and constructs a new city, using an industrial system to crush the primitive wars between ninja clans.

Years later, when Hashirama Senju sees rows of chakra heavy cannons firing in unison from atop the city walls, he is stunned. “You call this a ninja village?”
