The blue-gold moonlight in the emergency room split time and space. When Lin Xiaowan, an intern medical student, woke up, she was actually lying in a Tang Dynasty coffin in her wedding clothes. The "bride" who was supposed to marry her brother was using a silver hairpin to open the poisoned girl's teeth. The flash of anatomical diagrams on the bronze jade necklace around her neck quietly opened the suspenseful prelude to the millennium of Chang'an.
When the lancet and the silver needle clashed in Hu Shang's mansion, when pasteurization met the steam rising from the decoction pot, Lin Xiaowan took the memory of modern medicine and ran rampant in the prosperous Tang Dynasty. Lin Xiaowan pieced together the shocking truth while treating diseases and saving people: Chang'an City during the Zhenguan period was actually a "human body laboratory" for a mysterious force, and the jade around her neck was the key to opening the rift in time and space. When Yujue projected the three-dimensional anatomy of Chang'an City at the Xishi Night Market, and when the black shadow took off his mask to reveal eyebrows similar to Pei Ji's and mentioned "space-time cancer," a medical conspiracy and time-space game spanning ancient and modern times was unfolding with Lin Xiaowan as the center.
