The ancient immortals fished for the world's fortune, controlling the rise and fall of dynasties. The cultivation methods of the ancient cultivators fell into decline, until a generation of geniuses unwilling to accept their fate emerged from nowhere. They founded the Golden Core Dao, slew immortals high above the nine heavens, and guarded the Heavenly Gate as Gatekeepers. From then on, immortals belonged to the immortals, and mortals to the mortals. Fifty thousand years later, a rumor suddenly spread through the Immortal Realm: the next Gatekeeper would be born in the cultivation world. Become the Gatekeeper, and you will be granted the fruit of immortality.
