After being reincarnated into the ninja world, Umino Sasuke found himself in the body of an ordinary chūnin. Born to a civilian family, possessing mediocre chakra reserves, and knowing little more than the three basic Academy techniques, he was the definition of cannon fodder.

In a world where the great clans monopolize the most powerful ninjutsu, Sasuke had no Kekkei Genkai or any innate advantage. To survive the Second Great Shinobi War, his only weapon was a scientific mind, which he used to deconstruct and push the most fundamental jutsu to their absolute limits.

While Konoha's high command used the "Will of Fire" as an excuse to harvest cannon fodder, he analyzed the Transformation Jutsu to develop animalistic breathing methods and enhance his physical body.

While the geniuses of the clans slaughtered their enemies with their Kekkei Genkai, he perfected the Clone Jutsu to create solid avatars, nearly as versatile as human puppets.

And while legends altered the battlefield with techniques like the Flying Raijin Jutsu, he studied the humble Substitution Jutsu to develop a form of near-instantaneous teleportation.

This is the story of how a common ninja, armed only with his intellect, redefined the very limits of power.

So, I realized I made a few mistakes translating this novel, so I'm re-translating it. That means I'm going to delete the chapters and re-upload them up to chapter 40. I recommend you give it a re-read! Thanks for all your comments!
