A prophecy is passed down through the Cultivation World: "Immortality is not bestowed by Heaven; ten thousand years are all a bitter journey." Cultivators spend their whole lives climbing the path to immortality, only to find themselves stuck at a bottleneck, watching helplessly as their lifespans run out.
Chen Sheng's soul transmigrates into the Cultivation World. From a small village to his first encounter with cultivation techniques, his sole aim is to live forever.
As time goes on, he gradually comes to understand that immortality has never been about "how long you live," but whether, through the long years, you can still hold fast to the Dao heart you had at the beginning.
