A Billion Years of Cautious Cultivation

Blurb:

After five hundred years, ordinary Lin Jing has finally completed his missions and retired from the quick transmigration Bureau. The Bureau Chief was moved to tears with joy and could hardly wait to hand him his retirement gift before hurrying this good-for-nothing, who had wrecked countless minor worlds, back to his original world.

Back in the present, Lin Jing's cancer has reached its final stage. When he opens the retirement gift from the System, he gets a Lifespan Bonus System, which merges with his body.

The System shows that he has only one hour of life left! What, is he going to die as soon as he gets back?

Fortunately, the Lifespan Bonus System lets him increase his lifespan by reading all kinds of books. As long as Lin Jing reads enough, death will never catch up with him.

With his endless lifespan, Lin Jing witnesses humanity's rise, decline, resurgence, annihilation, and rebirth...

Meanwhile, amid the tides of history, he glimpses the path of immortal cultivation and enters the Qi Refining stage, becoming the first immortal cultivator. But his aptitude is poor. His inspired successors, the pitiful ones he saves, and even an orchid he casually enlightens all race ahead into the ranks of the mighty, becoming beings far beyond his reach, while he remains in the Qi Refining stage.

"It doesn't matter. My lifespan is endless. If I can't catch up with them, I'll just outlive them." As familiar faces disappear and the world changes beyond recognition, one mighty cultivator after another reaches the end of their lifespan and falls, while Lin Jing is still alive. He quietly cultivates immortality in seclusion, vying with no one, wishing only to live as long as Heaven and Earth.

Immortal cultivation is merely a way to protect himself.

The path to eternal life that others seek is already clear in my heart.
