Sang Yun had just finished her college entrance exams and left her miserable high school life behind. Looking forward to summer vacation, she transmigrated into a demon-slaying novel as the cannon-fodder senior sister: the Demon-Slaying Sword's master, who would sacrifice herself to the sword in the end.
The world of the book had fallen apart, with demons running rampant. Sang Yun had nothing going for her, and things went terribly from the start. She was close to tears and couldn't even swing the Demon-Slaying Sword.
As if that weren't enough, she could come back to life. After dying again and again, she broke down, gave up, and hid in a shrine to pray to the gods.
No one in this world believed in gods anymore. The shrine was in ruins, and the only company she had was a flaking golden statue.
Every day, she made offerings and prayed before the statue:
God, if you give me another chance, I'll train hard, strive to improve, and become the greatest leader of the righteous path.
In the end, Sang Yun sacrificed herself to the sword and purified the world.
As she closed her eyes, the golden coating peeled away from the statue, revealing a pair of eyes so handsome they seemed otherworldly, their downcast lashes like snow falling on a mountain peak.
"As you wish."

At first, Kunlun only wanted to repay his debt and grant her wish, helping her become the greatest leader of the righteous path.
He descended from his divine pedestal and entered the mortal world, rescuing her from misery and teaching her swordsmanship and immortal arts. He cared for her day and night, like a master and a father.
He thought that once her wish was fulfilled, he could return this borrowed human heart and go back to Kunlun to be a carefree immortal.
Until the woman's smile grew more radiant and her eyes shone ever brighter. He realized he could no longer bear it...
He couldn't bear seeing her gaze fall on someone else.
