Getting Stronger, One Illness at a Time

After transmigrating to a parallel world where spiritual qi revival had begun, plants, animals, and humans alike started evolving. Su Fan was terminally ill, and just as he was about to die, he activated the System.

The sicker he got, the stronger he became. Every illness gave him a new ability.

Bone cancer = Shikotsumyaku

Pinkeye = Sharingan

Concussion = Kyoka Suigetsu, the Zanpakuto

Stomach ulcer = Fire Dragon Slayer Magic

Kidney deficiency = Imperial Arms: Extractor Devil

Heart attack = Conqueror's Haki

The Great Sage slime... and countless other abilities. And so, history's strongest sickly man was born. One second, he was on one knee, coughing up blood. The next, he had killed his opponent instantly.

"Bro, your face is as white as a ghost's. How can you fight so well? Quit messing with us, okay? Please, bro, stop pretending!"

Su Fan: "Cough, cough... I... really am sick... cough, cough!"
