An Lingrong, the successor of traditional Chinese medicine, traveled through time and became a sickly noble man, dormant in the cold palace. He relied on his peerless medical skills to save himself and the prince from the brink of death, and his talents first emerged. The illness in the harem was hidden. She used the golden needle as a sword and the medicine as a strategy to cure the hidden diseases of the concubines and the stubborn diseases of Princess Ping, and quietly weaved a network of connections. Until the emperor contracted a strange disease that the hospital was unable to deal with, she turned around with a needle in her hand. From then on, the name of Xinglin's Holy Hand shocked the palace. He broke through the treachery with his benevolence within the red wall, controlled the storm with his medical skills, startled people every step of the way, and eventually became a legend for a generation.
