On the Red Abyss Continent, where the demon race and the immortal realm have stood in opposition for ten thousand years, a fated romance begins in blood vengeance and ends in redemption.
She is Yun Qingyue, the most brilliant disciple of the Lingxiao Sect, blessed with a Heaven-grade spirit vein and wielding the Demon-Suppressing Sword. She vows to slay every evil spirit under heaven. He is Xuan Jin, the Supreme of the demon race, awakened from an ancient seal. His Heaven-Burning Demonic Flame can scorch the eight directions, and after ten thousand years of solitude, he awaits the chance to take his revenge.
The demon she is ordered to hunt turns out to be the boy who once protected her with his life a hundred years ago. And when he discovers that the only way to quell the backlash of his Heaven-Burning Flame is her heart's blood and tears of true love, the red thread of fate binds them tightly, only to fray strand by strand across the chasm between righteousness and evil.
From crossing swords to entrusting their lives to one another, from the battlefield between two realms to the secret lands of the Nine Heavens, they unravel an ancient mystery amid their tangled love and hate: immortals and demons are merely two sides of the human heart, and fate can be changed with a single thought.
When the world-ending flames rise once more, she is willing to burn her immortal bones as kindling, and he would scatter his demonic soul to fuel the fire, all to rekindle a single spark of hope in the ashes. This time, not for all living beings, but for you.
