Naruto: Becoming Stronger by Healing Uchiha Mikoto

Hirakawa Seisui, a transmigrator reborn in the Hidden Leaf Village.

In the ninja world, where bloodlines reign supreme, he is merely a civilian-born ninja-nothing but cannon fodder on the battlefield.

But fate leaves a way out: he bonds with the Medical Ninja System.

The good news? The system has raised his talent for medical ninjutsu to the highest level. He now possesses an Innate Medical Sage Physique.

The bad news? It only improved his talent for medical ninjutsu. On the battlefield, he is still just cannon fodder.

"What kind of trash system is this? If the other transmigrators find out, they'll look down on me and think I can't afford a decent one."

Treatment of Mikoto Uchiha completed. Reward: one golden orb.

Congratulations! You have obtained Demonic Illusion: Tree Binding Death.

"Sorry, System. I admit I was a little too loud just now."

Every completed treatment earns him an orb as a reward.

Chakra, ninja tools, ninjutsu-even kekkei genkai. Everything is up for grabs.

Years later, now invincible throughout the ninja world, Seisui declares, "I'm just a medical ninja. I don't have the kind of weak power everyone else does."

Everyone: "Listen to yourself! Is that even something a human being would say?"
