After a five-year relationship, the girlfriend jumped into the arms of a rich businessman, and together with her lover beat Chen Hao bloody, throwing him out of the house. Left with no other way out, Chen Hao rummaged through his grandfather's relics to find a box of yellowed engagement letters and a medical manual of immortality concealing a massive secret. Was his grandfather just a poor village doctor? What he left behind is enough to shake the entire wealth of Shanghai's elite families. Overnight, the poor guy awakened heaven-defying medical skills: a single silver needle snatches people from the hands of the King of Hell; a wave of immortal energy forces a grandmaster to yield on the spot. Those who once laughed at him for wanting a swan's meat are now queueing up begging him to save their lives; the wealthy heiress who once came to break off the engagement is crying to marry him. Chen Hao sneered: Don't rush, one by one.
