The Nine Domains have never been a pure haven untouched by the mortal world. They are a low-dimensional prison, where the supreme Outer Gods have spent billions of years cultivating the Dao. In ancient times, the ancestors saw through the Heavenly Dao's game of chess. They sealed the nine anchors of heaven and earth with their own bodies and left behind the Nine Domains' fragments of jade, enduring in silence for countless ages to delay the harvest of the heavens.
The protagonist, Cang Nantian, was born in this world. After gathering all nine fragments of jade, he cultivated the one-of-a-kind native counter-path known as the Origin Sequence Dao of Suppressing the Ruins. Together with Gu Yuheng, Xiyue, Su Yan, Aila, Akai, and the others, he repeatedly quelled void rifts, repelled waves of invaders from beyond the domains, and fought the Watchers who had kept vigil for countless ages, overcoming one world-ending crisis after another.
In the later stages, the group uncovered the ultimate truth: every war and calamity was part of a game in which the supreme gods deliberately forged their blades. To sever the Nine Domains' fate once and for all and end the harvest that had continued for countless ages, the team crossed worlds to strike against the supreme gods themselves.
In the hopeless battle, the four companions sacrificed themselves to pave the way, self-destructing their Dao foundations and gravely wounding the seemingly invincible supreme god. Cang Nantian exhausted the source of his Great Dao to seal the divine authority and win eternal freedom for the Nine Domains, but fell into a rift in space and time, his fate unknown.
The game of chess spanning countless ages collapsed, and the world finally found peace. All that remained was the legend of the heroes, and a faint, undying light deep within the rift, waiting for an unknown return.
