A boy that was imprisoned for millions of years has regained a mortal body.

He became a disciple of the declining Cleansing Incense Ancient Sect where its patriarch used to be his disciple. Now he will bring this sect back to its former glory.

This is his journey to reach the apex and take revenge on those who had imprisoned him.

This is his story of meeting old friends and making new companions.

This is his path of traversing the Nine Worlds and becoming the next ruler of the Heavens.

Several millennia have passed and the golden age of experts has passed. A master whose disciples once were the most exalted Immortals among the 9 worlds had all left him. With his mortal body, mortal physique and mortal life wheel… he shall sweep the 9 worlds and take what is rightfully his.

On that day, the fog blocked everything.

On that day, he became the captain of a ghost ship.

On that day, he stepped through the thick fog and confronted a completely subverted and fragmented world— the old order had vanished, strange phenomena dominated the endless seas beyond civilized society, and isolated island city-states and fleets of ships challenged the sea that had become the last ember of lights for the civilized world. All of this while the shadows of the old days were still stirring in the deep sea, waiting to devour this world that was about to die.

But for the new captain of the ghost ship Vanished, there was only one question he had to consider first — Who knows how to drive this ship?!

Seo Eun-hyun, an ordinary office worker, is suddenly transported to a cultivation world during a company retreat. Unlike others blessed with spiritual roots and talent, Eun-hyun is powerless—unable to cultivate, fight, or even survive on his own. For fifty years, he lives in quiet insignificance... until death.

Then, he wakes up—back at the start of it all.

This isn't reincarnation. It’s a return. Again and again, he relives the same life in this brutal world, each time with memories intact. Trapped in an endless cycle, Eun-hyun resolves to break free—not by overwhelming force, but by persistence, cunning, and learning from every failure.

Through slow, methodical growth, he begins to carve out his own path in a world where strength rules, and the weak are forgotten. As he unravels the mystery of his regression and confronts hidden powers that bind him, one question remains:

How many lives must he endure before he can finally live his own?
