A grave sin in the Heavenly Realm, three trials in the mortal world. Is it brotherly devotion, or an emperor's inscrutable heart?
Separated in the chaos of infancy, they scattered to the ends of the earth. Yet fifteen years later, a pledge made by their fathers brought them together again on Mount Song.
Qiao Yu keeps his promises and guards the frontier with benevolence; Yu Jing is ambitious, his sword pointed at the throne; Zi Rong is free-spirited, concealing her identity and her womanhood.
The three became sworn siblings and pledged to fight side by side and build an unprecedented legacy.
But the web of power is intricate, and hearts are fickle.
When Yu Jing schemed to seize the throne, framing his sworn brother and forcing his sworn sister into marriage, their past bonds proved no match for the empire.
"Once I succeed, you will be my queen."
But he wanted the throne, while she wanted peace for all under heaven.
On her wedding day, Zi Rong faked her death and escaped, then returned in armor.
The former "General Zi Rong" led an army to lay siege to the city in a woman's body, coming to rescue the brother who had always held fast to the righteous path.
"You want power. I stand by loyalty. In this trial, you lost your heart long ago."
At last, they faced off above the palace halls.
Would the siblings become sworn enemies, or was this karmic reckoning ordained by the Heavenly Tribulation?
As the token shone once more and auspicious clouds descended, the love and hatred of mortal life were merely a trial before returning to one's rightful place...
