A drop of blood awakened her after a century of slumber. A single tear once shattered her world. Wen Ruan was a ginseng root that had cultivated for a hundred billion years. When she first took human form, she was filled with kindness, but in the Republican era, the time she trusted most, the person she loved fed her poison with his own hands. As her heart broke and her spirit faded, her spiritual power scattered and her soul split in two. Kindhearted Wen Ruan fell into a deep sleep, while “Wen Ye,” who bore all her resentment, vanished into the world with the seed of destruction.
A century later, the wealthy CEO Shen Yanchen is trapped in a desperate situation when his car plunges off a cliff. As he lies at death's door, his blood accidentally nourishes Wen Ruan's sleeping true form. A miracle occurs: he comes back from the dead, and a breathtaking woman in a tattered Republican-era dress, untouched by the dust of the world, awakens in a daze amid a burst of light.
From then on, the science-minded CEO is forced to look after a thousand-year-old ginseng spirit who knows nothing about the modern world, has severe cleanliness issues, and treats him as a “walking wallet.” He shows her the splendor of modern life, while she purifies the evil spirits plaguing the world. But Wen Ruan soon discovers that she is not the only one who has awakened. “Wen Ye,” who looks just like her but wears ancient clothes and paints with blood, is on a killing spree. She is the other half of Wen Ruan's soul, the past she cannot leave behind, and the nightmare of darkness she must face.
When Wen Ye sneers, “Sister, and you still dare to trust a man's words?” Shen Yanchen pulls Wen Ruan close behind him and says firmly, “Don't be afraid. I'm here.” On one side is the warmth of the present, which he is sworn to protect; on the other is the painful past rooted in her very being. When good and evil finally become one, and consciousness is torn apart in the confusion of love and hate, Shen Yanchen realizes that his greatest fear is losing the woman who depends on him and can't help complaining about him, Wen Yuan.
