[Both Leads' First Love + Sweet or Sultry + Fierce and Sensual + Happy Ending]
Foxes become spirits after a hundred years, demons after a thousand, and human after ten thousand. Once a nine-tailed fox demon obtains a stone body, she needs only one sincere heart to become human. Before King Zhou immolates himself, he cuts out his sincere heart and offers it to the nine-tailed fox. She refuses to eat it, and Jiang Ziya beats her Original Spirit out of her body, returning her true form to stone.
Reborn Yu Si possesses a modern soul and peerless medical skills.
She wanders among the various states of the Western Zhou, healing the sick and saving lives, all so she can collect a drop of blood from each person she cures to nourish the Seven-Soul Flower. When it blooms, the Main God, Jiang Shang, will return.
Feng Qingchen, descendant of the nine-tailed fox, is half human and half demon. He beats up bullies and scoundrels, all to chase his wife and beg her for a sincere heart.
[Little Theater]
Former father: "My worthless daughter is unfit for refined company."
Yu Si: "Do I look like your daughter? Poor eyesight is an illness. It needs treatment!"
Real father: "Whoever dares speak ill of my Si'er, I'll flatten their family's ancestral graves!"
Yu Si: "Father, leave me the bones to use as fertilizer!"
Former brother: "Don't call me brother. I don't have an shameless sister like you!"
Yu Si: "When did I ever call you brother? Bad hearing is an illness too. It needs treatment!"
Real brother: "I have only one sister, Si'er. Whoever dares set their sights on her can answer to my fists!"
Yu Si: "Brother, there's half a fox over there, and he won't get out of bed!"
The world: "The younger Yu daughter is a mystery. She killed her mother and brings harm to all living things."
Feng Qingchen: "All mouth, no heart. Away you go!"
The world: "When the young master smiles, all beings are captivated!"
Yu Si: "How could they not be? He digs out hearts and plucks out brains! Come on, line up and take a number!"
Feng Qingchen: "Wife, all I want is your sincere heart!"
Yu Si: "I've got a needle core. Want that instead?"
