He also tells them to accompany him to the lake after class to enjoy the beauty of the maple trees. He then tells the students that he has developed a new medicine, hehuan powder, which has a remarkable effect on the body.

He says that the effects of his medicine are even better than he expected, and that they should not be afraid of him. He asks the students not to disturb the good spirits of other students, but to get lost. He promises to take care of the students if they continue to talk trash about him.
