A world of "revenge and inheritance of medical ethics". A "revenge novel". Through the stories of orphans from three families, the proposition of "what does a doctor do" and "what does inheritance do" are discussed - the real "green bag" is not in the secret scroll, but in every injection, every prescription and every word of comfort that the doctor uses to protect life. In the end, it is not only the medical skills that make the patient last forever, but also the benevolence of "I would rather give up my life than to help the world in vain."
