Because the Qilin Immortal Official cared for the decline of the people, he asked the Ninefold Jade Emperor to come down to earth. However, the people were not as good as the gods, and they could not save all the people with only their meager efforts. The Medical Immortal was willing to spend his whole life helping the world, not only for the common people, but also for the beauty.
