One-on-one, gender transformation, a bad woman seduces an innocent young man, an immortal couple.
"Do you want to die, or do you want to live?"
The woman looked down upon the world as she gazed at the young man.
"I want to live, my dear big sister..."
"Then from now on, you're my servant. Whatever I tell you to do, you do it. Understand?"
"Yes."
..
That year, rain fell beyond the strings of the apricot blossoms. The young man touched his head and answered a different question: "All these years, I haven't dared think about you too much."
"You heartless little bastard."
That year, by the banks of the Luo River, the young man played his zither and stared in stunned disbelief. "So you're an immortal, just like the Goddess of the Luo River, big sister?"
"So what if I am? Even immortals can be with you."
That year, in the Burial Soul Valley, behind the red curtains, she pinned the young man beneath her and breathed into his ear. "Don't talk. I'll do the moving."
That year, amid the Yin-Yang Grand Formation, they made love for ten days and ten nights before finally stopping.
At last, the young man took the initiative. He pressed the girl beneath him and breathed into her ear.
"I want to be big sister's dog."
Many years later.
By the banks of the Luo River, she wore a blue robe, a bell tied to a red cord around her wrist ringing clear and bright.
She watched the man stroll along the river with a little girl, then sailed over to meet them.
"Brother Qingrong, it's been so long. Your hair has gone a little gray."
"Here, eat this."
She handed the man a pill of immortality.
"Eat it. A lifetime means a whole lifetime. Not one month, one day, or even one hour less."
She watched the man take the pill with a smile, then asked gently, "Would you rather call me Xie Youxuan or Xiao Xuan'er? Either is fine."
"I like calling you big sister."
"That works too."
