In the pre-Qin period, there were countless immortal monks in this world, who lived for thousands of years, moved mountains and reclaimed the sea, feathered and soared, and the immortals of the world were also. But the heavens and the earth changed dramatically. The immortal qi in the world has become extremely thin, and one of the immortal powers has fallen one after another.

In this world, the qi of immortality is thin and cannot be cultivated. But Chen Jianghe unexpectedly discovered that the speed of time in this world is thousands of times faster than that of the real world. Cultivating the secret art of immortality in the real world for one day is equivalent to cultivating in this world for three years. A secret art of immortality, it takes three years to get started, thirty years to raise longevity, three hundred years to evolve and immortalize, and three thousand years to feather immortality. In Chen Jianghe's hands, it only takes three days to forge the introductory body, only thirty days to raise the longevity species, only three hundred days to evolve the immortal body, and only three thousand days to feather immortalization. Since then, Chen Jianghe has embarked on a vast road of immortality in this world......
