I'm the Dragon King & Legendary Healer

A legendary figure walks the streets in the guise of a ragged beggar, unrecognized by anyone. Meanwhile, the eldest daughter of a wealthy financier lies gravely ill with a mysterious affliction that no physician has been able to treat, despite her father posting a generous reward. When the second daughter drops a few coins into the beggar's worn bowl, he offers to grant one of her wishes and follows her home. Her father doubts that a vagrant could save his dying child, yet the man's calm, remarkable skill is about to be tested.
