In the seventh year of Jinghe, Cangwu Mountain was blocked by heavy snow. Xie Jingxing, the former Taifu who lived abandoned in the mountains, rescued a dying young girl at the foot of a cliff and named her Ayan. The girl couldn't speak, but she could identify poisonous herbs intuitively. She also had a pair of amber eyes that were exactly the same as a little fox he rescued ten years ago.
Ayan gradually grew up in Cangwu Mountain, studying and studying medicine with Xie Jingxing, and spent several years of quiet time in the medicine house with one person and one fox. However, there is an undercurrent surging beneath the calm surface - there is a thousand-year-old ancient tomb hidden deep in Cangwu Mountain. Someone above the court is secretly tracking the traces of the "monster", and the power of the nine-tailed white fox sleeping in Ayan's body is quietly awakening as she grows up.
Xie Jingxing was a young tutor who was famous in the capital. Three years ago, he was assassinated by someone. He was hit by seven knives and three arrows. His meridians were severed and his legs were paralyzed. He was heartbroken, but found a reason to live again in Ayan. The two work together to uncover a series of bizarre cases - monsters in ancient tombs, forbidden love, human and ghost couples - every clue points to a shocking secret: Ayan is not an ordinary fox demon, her existence affects a fate that happened thousands of years ago.
When a storm swept across the court, the imperial preceptor and the powerful officials joined forces to force the palace to kill the "monster that was causing harm to the country". Xie Jingxing blocked A Yan with his broken body, and A Yan finally remembered that she had been waiting for him for a thousand years.
Intent: True love transcends the differences between humans and monsters, and two broken souls find their complete selves in each other.
