At the coming-of-age ceremony, sixteen-year-old Crown Prince Xiao Jingzhao awakens an ancient sword that has guarded the nation for three thousand years, using the blood of the emperor.
The Swordheart of the Cosmic Era enters his body, awakening his talent for the sword. His mortal body transforms into a Daoist physique, and he takes his first step onto the path of cultivation.
Everyone thinks the crown prince is pampered, ignorant of state affairs, and unsuited to cultivation.
But they don't know that Xiao Jingzhao establishes his authority with the sword and controls the board with strategy.
At court, he quietly reclaims power, restores order, purges corruption, and leaves no one daring to look down on him.
At the borders, he leads the charge with sword in hand, drives back the invaders, slays the enemy commander, reclaims lost territory, and avenges a century of national humiliation.
The noble clans refuse to submit? He breaks their stranglehold with a single sword, forcing the entrenched clans to bow their heads.
Enemy nations invade? He leads his army in a sweeping campaign, bringing down the three dynasties that have oppressed Great Jing, one by one.
With a single sword, he secures the realm. With his own strength, he ushers in peace. From a crown prince in a kingdom tossed by storms, he rises to the supreme throne and unites the Nine Wastes and ten thousand nations.
But when he breaks through the boundary between worlds, he discovers that the conflicts of the mortal realm are no more than a drop in the ocean.
Darkness spreads across the Cangyan Realm. The truth behind the ancient catastrophe comes to light, and a crisis threatening all three realms draws near.
And Xiao Jingzhao, master of the Sword Dao of the Cosmic Era, will become the only one in all creation to wield the sword and safeguard the Dao.
