Liang Jintang, the legitimate son of the Town-North General's Mansion, was poisoned by his stepmother and fake younger brother at age fourteen, leaving him with chronic ailments and a cold, reclusive disposition. Su Zhiling of a traditional Chinese medicine family, in order to save her father, was forced into a chongxi marriage to enter the mansion. Taking his pulse, she saw through the truth of the poisoning, and secretly applied medical arts to detoxify him. From mutual probing to falling deeply in love, she discovered that the benefactor she had searched for for ten years was none other than this sickly husband; his blood-soaked revenge was also borne shoulder to shoulder by her. When the stepmother and fake brother wreaked havoc and the Liang family collapsed, the two fled for their lives. To save him, she willingly split her liver and harmed her body; to protect her, he fought bloody battles unto death covered in scars.
