System: The Golden Needle Healer

Science-track top scorer Lin Xi is forcibly bound to the "Legacy of Traditional Chinese Medicine System" and made to give up her dream of attending a top university to study traditional Chinese medicine instead. When she first meets her rich roommate, Gu Heng, the two clash constantly over their class differences and lifestyle habits. The System opens the "Qihuang Secret Realm," helping Lin Xi master medical skills at lightning speed, but it also draws skepticism from top students and suppression from Western medicine advocates. Gu Heng seems cold on the surface, yet repeatedly comes to her aid: he uses his family's resources to resolve a library dispute, fills gaps in Lin Xi's diagnoses with his knowledge of dentistry, and even takes a knife for her when she is attacked by thugs.

When traditionalists gang up on Lin Xi for improving an ancient prescription, Gu Heng turns down an offer from a prestigious overseas university, sells his stocks, and starts the "Mingheng Dental Clinic" to support her. Their unspoken feelings break into the open amid separation and crisis: Lin Xi guides acupuncture treatment from overseas to save Gu Heng, who is gravely injured in a car accident, while Gu Heng exposes academic corruption to clear Lin Xi's name. In the end, they cure a patient with uremia using integrated Chinese and Western medicine, overcoming a crisis in the passing down of medical traditions. The System becomes a physical secret realm in the clinic's basement, while their fingers clasped beneath the moonlight and the gold acupuncture needle case engraved with the characters "Heng Xi" bear witness to the path these straight-laced doctors forge together to carry their legacy forward.
