She is Feng Yuechen, who carries a personal space and has hidden all the world's rare medicines and lost classics. Her medicine can revive the dead, and her poison can kill people. She also possesses the pinnacle of ancient martial arts, yet she walks quietly in the world.
He is Di Wentian, an emperor with overwhelming power, but he is trapped by the cold poison that bites the bones. He is surrounded by secret guards, but he can't find anyone to trust in his heart.
During the night consultation in the Forbidden Palace, a woman in plain clothes quietly appeared and broke the emperor's alertness with a "Qinghan Pill". The golden needle warded off the evil, and her fingertips were as steady as a rock. They not only drove away the evil, but also touched each other's heartstrings.
One uses the power of the emperor to protect the person he wants to protect, and the other relies on her medical skills to relieve the poison that is haunting him. It was originally an encounter of "each takes what he needs", but in the intertwining of the court affairs and the secrets of the world, the two aloof hearts gradually get closer. The hidden master of the world of cultivation, who is both skilled in medicine and poison, and the cold emperor who controls the world will compose a touching love song in this earthly chess game, standing side by side and falling in love with each other.
