The Mingxin Clinic, steeped in the fragrance of medicinal herbs in Chang’an, hides a secret known to no one. Su Mingxi, a modern medical student who transmigrates into the past, becomes the clinic’s heir, only to discover that the ancient carvings on its pillars seep dark red stains every night. The words, “A doctor’s skill may be great or small, but a patient’s condition is never insignificant. Anything involving a life is a serious matter,” lead her to uphold a healer’s compassion in this unfamiliar world, while also pushing her toward the abyss of fate.
The pattern on the jade pendant at the waist of the cold and austere swordsman Pei Yanzhi is identical to one in the clinic’s forbidden texts. Whenever he draws near, Su Mingxi can hear the sound of chains dragging. As the two meet, shadows of the Dark Moon Cult quietly emerge. The blood moon approaches, and rumors of its arrival run rampant. An old man with a demonic heart in each of his seven orifices, a red-robed enchantress with eyes in her hair, demonic soldiers with spider bodies and human faces... Behind these bizarre phenomena lies a shocking conspiracy spanning a century.
Su Mingxi uses the clinic’s secret arts with her silver needles to fight evil, only to realize that the needles she uses to save lives may be connected to the Dark Moon Cult’s sorcery. When Pei Yanzhi’s sword shatters, unfamiliar faces flash among the fragments, making the truth even more elusive. Her vow, “As long as there is a way to save someone in this world, I cannot let a life fade before my eyes,” grows heavier amid the layers of mist.
They think peace will follow once the Dark Moon Cult’s conspiracy is crushed, but crimson eyes beneath the ruins and the black-robed remnants carrying the scent of medicine in the alleys warn that a new crisis has arrived. Can Su Mingxi and Pei Yanzhi hold fast to their convictions through the mist and uncover the buried past?
