Lin Wei, a female surgeon in the 21st century, accidentally transformed into a bullied concubine in the palace of the Minister of Rites of Dajing. Her birth mother died young, and her aunt and sister made things difficult for her. When she fell into the water and was about to die, she accidentally activated the mutton-fat jade pendant left by her birth mother, opening a portable space that contained spiritual springs, black earth, and a wooden house in the medicine garden.
The spiritual spring can heal injuries and strengthen the body, and the black soil can quickly produce strange medicines. Space has become her greatest confidence to survive in adversity. In order to escape from the devil's cave of the prince's mansion, she had no choice but to get involved in the draft, and entered the harem with a humble promise.
Within the palace walls, murderous intentions are everywhere: concubines compete for favor and poisoning, factions fight openly and secretly, and the palace is full of secrets. Lin Wei relied on her superb medical skills, space assistance and modern wisdom to break through the desperate situation - solving strange poisons, curing serious illnesses, saving key people and gaining connections; discerning people's hearts and tricks, avoiding deadly traps again and again; using medicine as a matchmaker and wisdom as a blade, she accepted the promise of a concubine who was being trampled upon by others, and counterattacked and was promoted step by step, winning the emperor's attention and respect.
When the cold medical concubine meets the deep emperor, and when the personal space collides with the intrigues of the deep palace, she not only has to survive in the treacherous harem, but also needs to find out the truth about the death of her biological mother, protect the people around her, and finally find her own path to glory within the red wall.
