Naruto: The Ultimate Red-Eye Disease

I transmigrated to the Hokage world and became the grandson of Kagami Uchiha and the younger brother of Shisui Uchiha.

Seriously? This identity comes with a ridiculous amount of pressure.

Luckily, every transmigrator gets a golden finger: the National Server Enhancement System.

Who am I? Do you even know who I am? Just give it to me, Dad!

The National Server Enhancement is gone, the enhancement is gone, and the Supreme Emperor of Black Iron is here!

A +12 Black Iron Enhancement Scroll? No worries, the Ancient Relics Codex will make sure it works. Hey!! It worked, it worked!!

Your Great Fireball Technique is so weak? I'll enhance it to a red +12. It'll be about as powerful as Madara's Majestic Destroyer Flame.

Your taijutsu is no good? Enhance it, then train in the Eight Gates.

Your Sharingan only has two tomoe? Enhance, enhance, and I'll give you a Rinnegan!
