Lin Wei, a third-year clinical medicine student, traveled through the prosperous Tang Dynasty with a luminous old well and an ancestral plum blossom pendant, and the gears of her fate began to reverse. She fell from the dissecting table of the medical school into the carved beams and painted buildings of Chang'an. She used modern medical knowledge to save the seriously injured royal family member Xiao Jingyan, but she was accidentally involved in a shocking injustice case that spanned twenty years.
He is a gentle and steady royal prince who shields her from criticism in the court and accompanies her to solve the epidemic crisis; she is a benevolent medical officer from another world, who subverts the medical theory of the Tang Dynasty with iodine and suturing techniques, and investigates the truth with tenacity and wisdom. From the first encounter in the Chang'an Medical Center, to the life-and-death struggle at Longyou Military Camp, to the thrilling pursuit of evidence at the foot of Zhongnan Mountain, a plum blossom pendant connects the secrets of time and space, and half of the broken decree hides the grievances of the deposed prince.
When the shadow of aconite poison enveloped the court, the Prime Minister's gang members were pursuing him step by step. Lin Wei used the autopsy report as a blade, and Jamel Xiao used his iron-blooded wrist as a shield to work together to uncover the layers of the shady story of swapping food and grass and poisoning Zhongliang. They not only want to save the prince Zhaoxue who died in vain, but also protect the deep love that has spanned thousands of years - in this era without antibiotics, she used medical skills to save lives and heal the wounded, and he protected her with his sincerity. In the end, the lights of "Jishitang" illuminated every corner of Chang'an, and this love affair that began by accident in time and space finally became a good story that has been passed down for thousands of years.
