I was reborn into Konoha as Orochimaru’s disciple.
The first thing I realized?
This world doesn’t even have a word for cancer.
In my past life, cancer was the ultimate despair.
In this life, it becomes my sharpest weapon.
With a researcher’s mind and a strange [Research Panel], I start dissecting everything:
– Hashirama’s cells, Uchiha eyes, Hyūga bloodlines, even souls used in Edo Tensei.
– Turning cancer cells into a silent killing jutsu that pushes enemies into terminal stages.
– Using nicotine, radiation and chakra to create modern bio-weapons in a ninja world.
– Upgrading Edo Tensei, body-modification and regeneration in the pursuit of true immortality.
– Treating tailed beasts, parasites and cursed seals as nothing more than experimental samples.
While Konoha celebrates the rise of the Fourth Hokage, the shadows keep thickening:
Danzo wants to own my research.
Orochimaru wants to drag me deeper into taboo.
The Uchiha are walking toward genocide.
The night of the Nine-Tails is drawing near.
I refuse to be a disposable tool, a scapegoat, or another corpse on the table.
If this world treats people as experiments…
then I’ll be the one holding the scalpel.
A cold, dark-humored scientist MC + Orochimaru + ROOT + forbidden jutsu + ninja politics.
Watch science itself become the most terrifying power in the Naruto world.
