Xin Ning, the backbone of the Traditional Chinese Medicine Department of a modern tertiary hospital, is a master of acupuncture and massage. However, while rescuing a patient, he was caught in a strong light by a sudden leakage of electricity. When he opened his eyes again, he was exposed to the war-torn Northern Han Dynasty.
She became an orphan girl who lost her parents due to the plague in a border town. The dilapidated thatched huts, lack of medicinal materials, and war disasters that could strike at any time made it difficult for her, who was accustomed to modern medical conditions. In order to survive, Xin Ning regained her traditional Chinese medicine skills, used a few silver needles to save children with persistent high fevers, and used herbal prescriptions to alleviate the epidemic in the town, gradually gaining a reputation as a "living Bodhisattva" in the local area.
During a medical visit, she accidentally rescued the seventh prince of the Northern Han Dynasty, Zhao Heng, who was being chased by assassins and seriously injured. Zhao Heng was suspicious and cold, but he was attracted by Xin Ning's medical skills that were completely different from ancient methods and his calm and tenacious personality. In getting along with Zhao Heng, Xin Ning also saw his care for the people under his iron-blooded appearance, and his inability to control himself in the whirlpool of imperial power.
The border is in crisis, the plague has reappeared, and the conspiracy in the court is pressing closer. Xin Ning uses traditional Chinese medicine as a weapon to save lives and heal the wounded in troubled times, and has become Zhao Heng's most solid backing. The two went from testing each other to trusting each other. In the turbulent situation of the Northern Han Dynasty, they composed a touching love song that spanned time and space and used medical skills as a medium. However, they also had to face many tests from the times, imperial power and destiny.
