The physician of the Song Dynasty, Sam, is sensitive and knowledgeable, and is skilled in the art of ambiguity. He is especially good at exploring the subtle and hidden, and solving difficult diseases.

There are many diseases in the times, and the people are suffering. Sam has traveled all over the world, covering deep mountains, visiting remote soils, and picking herbs to help people. He is compatible with medicinal stones, and has unique ingenuity. He often uses ordinary grass to cause illness.

Every time a patient comes, Sam will scrutinize his appearance, listen to his voice, ask his symptoms, cut his veins, and work hard to be precise. His heart is kind, and when he encounters the poor, he applies medicine without taking any text, so he praises his virtue from far and near.

His treatment is also not based on ancient methods, but on practical results. Or needles, or soup, or a strange prescription, all of which can be cured in response. Everyone calls Sam's technique, if God helps.

Sam tried to say: "The way of medicine is to help the world with benevolence, not to benefit the world, not to be tired by name, but to the well-being of the patient." As a result, its reputation spread far and wide, and there was an endless stream of people seeking medicine from all over the world.
