Original: People have diseases, and the medicine stone is unknown. Emperor Yan (the Dragon Family) began to nourish flowers and trees, to investigate the nature of cold and heat, and to distinguish the meaning of his princes and ministers assisting envoys. Taste 70 poisons a day and become a god, so I wrote a book to treat the nation, and medical ethics began.

The ancients were sick and medicine had not been invented. The Shenlong family began to taste all kinds of medicinal materials, observe the cold, warm, flat and hot properties of medicinal materials, and distinguish the relationship between medicinal materials like monarch, minister, assistant and envoy. Once he encountered 70 kinds of dramas in one day, and he magically dissolved these poisons. So I wrote down the medicinal properties to treat people, and China's medicine and medical career was born.
