I Gain a Century of Power Every Day, and You Call Me an Old Man?

In years of famine and chaos, demons run rampant, and the strong rule.

Gu Chang'an has spent sixty-two years in this world since transmigrating here. His hair is white, his back is hunched, and his body is covered in hidden injuries.

But on this day, Gu Chang'an awakens a System.

[One Day, a Hundred Years of Cultivation: Automatically gain a hundred years of cultivation every day, with unlimited growth. Ignore cultivation bottlenecks, learn any technique instantly regardless of its restrictions, and ignore the limits of the body.]

Ordinary geniuses need decades of cultivation to reach the postnatal and innate stages. Some spend their whole lives and still never advance beyond the Grandmaster realm.

But Gu Chang'an gains a hundred years of cultivation every day.

Thirty-six thousand years of cultivation in one year.

Three hundred and sixty thousand years in ten years.

Three million six hundred and fifty thousand years in a century.

While others are fighting tooth and nail over a cultivation technique, a pill, or a secret realm, Gu Chang'an has quietly amassed terrifying power, enough to make the entire continent tremble.

The Azure Wolf Gang comes to collect its annual dues?

He suppresses them with a single palm strike.

Demons and monsters wreak havoc among mortals?

A thousand years of cultivation suppresses evil spirits, ten thousand years breaks divine abilities, and countless eons make him invincible.

Little by little, Gu Chang'an goes from a frail old man in his sixties to a man with the vitality of a dragon, regaining his youth, and finally breaking through the ultimate limits of martial arts!
