The Mingxin Medical Center in Chang'an, filled with the fragrance of medicine, hides unknown secrets. Su Mingxi, a modern medical student, traveled through time and became a heir to the medical school, only to discover that dark red blood stains oozed from the ancient scratches on the beams every night. The sentence "A doctor's ability may be great or small, but the patient's condition is not great or small, and everything related to life is a big deal" allowed her to stick to the benevolence of a doctor in this strange world, and also pushed her into the abyss of fate.
The pattern of the jade pendant on the waist of the cold swordsman Pei Yan is actually consistent with the taboo books in the medical clinic. When he approached, Su Mingxi could always hear the dragging sound of the chains. When the two met, the dark shadow of the Dark Moon Sect quietly emerged. The blood moon is approaching, and rumors of the "blood moon coming to the world" are rampant. The old man with seven orifices and a demon heart, the red-clothed witch with hair and eyes, the human-faced spider demon soldier... Behind the strange phenomena is a shocking conspiracy that has lasted for hundreds of years.
Su Mingxi uses silver needles to use the secret skills of the medical clinic to fight against evil, but she is shocked to realize that the acupuncture skills used to save people seem to be related to the evil skills of the Dark Moon Cult. When Pei Yanzhi's sword blade shattered, the flash of unfamiliar faces in the fragments made the truth even more confusing. The oath "As long as there is a way to save it in the world, I will not let my life disappear in front of my eyes" becomes more and more heavy in the fog.
They thought that by destroying the Dark Moon Sect's conspiracy, they would be able to achieve peace. The scarlet eyes under the ruins and the afterimages of black robes with the scent of medicine in the streets indicated that a new crisis was coming. Can Su Mingxi and Pei Yanzhi keep their original aspirations in the fog and uncover the buried past?
