Cheng Yu is a weapon refiner who has been married to Yu Qingfeng, the Sword Venerable of the Ruthless Dao, for three hundred years. She has always been his devoted right hand.
She tempers his life-bound sword, helps him vanquish demons, works tirelessly for him day and night, and manages the entire sect, yet he has never cared.
At the grand contest between the immortal sects, Yu Qingfeng serves as a judge. To avoid any suspicion of bias, he asks her to withdraw from the master weapon refiner competition.
When his female disciple reaches a critical moment in her breakthrough, Yu Qingfeng personally guards her. That same night, Cheng Yu falls ill and nearly loses her life.
Three hundred years of devotion can't earn her even one moment of tender care.
In front of everyone, Cheng Yu asks for a divorce: "The Sword Venerable's heart belongs to all under heaven. Like the moon hanging high above, it shines on everyone but me. Today we part, each to follow our own path."
The crowd erupts in astonishment as she turns and leaves without looking back.
Yu Qingfeng thinks Cheng Yu is being far too willful.
In this dangerous world overrun by demons, she can't survive without his protection. Sooner or later, she'll come back and beg him.
But three months later...
Cheng Yu reopens her weapon-refining pavilion. Its halls are filled with divine weapons, drawing crowds eager to claim them. Countless immortals crowd her doorstep, half seeking to have magical weapons forged and half hoping to catch a glimpse of her exquisite beauty.
Later, just as Yu Qingfeng earns a fearsome reputation for slaying the Demon Venerable, he hears that Cheng Yu is going to marry another man. The Cangheng Sword Venerable, who once faced the collapse of heaven and earth without so much as changing expression, has his black hair turn completely white overnight, and his Dao heart shatters.
He storms into the wedding hall with his sword, crazed with the need to snatch her away. But Cheng Yu pulls her hand free: "Sword Venerable, be careful. Don't hurt my husband."
