The Barren Continent, where martial arts are supreme, and strength is honored above all.The once-in-an-era prodigy, Ye Chen, came forth with the ancient and unparalleled divine technique. He cultivated his martial veins, survived the thunder tribulation, merged with the spirit blood of true beings, and shook the six harmonies and the eight desolations with his martial prowess. He roamed the myriad realms and heavens, fighting across the world with the secret realm of billions of stars that were eternal and undying!An endless trove of treasures, worlds of bizarre wonders, sects, ancient clans, fairies, witches, friendships and enmities, and heated battles—all of it was contained therein.

In the mystical land of Teyvat, where elemental forces collide and secrets of ancient gods remain buried, an ordinary traveler awakens to an extraordinary destiny. Armed with unparalleled ambition and a mysterious system, they embark on a quest to become the Supreme Arbiter—the ultimate authority over all creation.The world of Teyvat is no stranger to conflict, but its hidden truths are more treacherous than any battle. Beneath the veneer of harmony lies a struggle for dominance among divine beings, and the enigmatic Heavenly Principles rule from the shadows.

However, their journey is far from peaceful. Ancient enemies, forbidden truths, and the ever-present gaze of Celestia test their resolve at every turn.As they ascend in power, unraveling secrets that defy the understanding of gods and mortals alike, one question looms: What does it mean to be the ultimate authority?Will they bring salvation to Teyvat, or become its greatest threat? The skies tremble, the earth stirs, and destiny itself bows before the rise of the Supreme Arbiter.
