Chen Daoxuan woke up one day to discover that he had been reborn into a vast cultivation megaverse on the brink of immortalization. This megaverse contains the great realms of Xuan Zhao, Kai Guang, Fusion, Heart Stirring, Lingji, Yuan Ying, Out‑of‑body, Dividing Spirit, Merging, Tribulation Crossing, and Great Vehicle. As long as one survives the Lingji tribulation and breaks through to the Yuan Ying stage, one can rely on the ever‑present Longevity Heavenly Law to achieve eternal life.

In this life, Chen Daoxuan was identified at the age of three as possessing top‑tier immortal talent, and thus entered the Shanhai Immortal Sect—one of the three thousand orthodox sects and eight hundred side schools, a sect with a lineage of true immortals. He reached Xuan Zhao at three, Kai Guang at eight, Fusion at twenty, Heart Stirring at forty, and attained the Lingji realm at sixty. Yet it was not until he turned three hundred that he survived the Lingji tribulation and became a top‑grade Yuan Ying, a true‑transmission disciple of the Shanhai Immortal Sect.

When he finally reached ten thousand years old, Chen Daoxuan suddenly realized that the golden finger, which had lain dormant for ten millennia, had revived and now possessed cross‑dimensional power. From that point on, Chen Daoxuan began to traverse the myriad realms, using them to nourish his own cultivation.
