With a Billion Extra Years to Live, You Call Me the First Brother of the Primordial Era?

Su Lang transmigrates to the Primordial Ancient World and gains an Immortality System.

The System has only one function: no matter what he does, it only increases his lifespan.

One hundred breaths: lifespan +1 day

One hundred push-ups: lifespan +1 day

Run ten kilometers: lifespan +2 days

And so a legend is born in the Primordial Ancient World: the ultimate old fox.

When his enemies are at their peak, Su Lang backs off. Once they grow old, he gets right in their faces.

"Revenge won't wait until tomorrow. It only waits fifty thousand years!"

"What, my enemy died of old age? Fine, I'll marry his great-great-great... granddaughter!"

Countless ages pass, and the Great Emperors rise and fall, yet Su Lang is still dancing on their graves.

When everyone begins to wonder whether Su Lang is the number one in the Primordial Ancient World, he smiles faintly.

"I just have a tiny bit too much lifespan. How did I become the number one guy in the Primordial Ancient World?"
