Prince Cheung had been First Minister of the land for thirty years. He was a man just and upright, now nearly ninety years of age. His son was called Whal, and was second in influence only to his father. Both were greatly renowned in the age in which they lived, and His Majesty treated them with special regard. Prince Cheung's home was suddenly attacked by goblins and devils, and when a young official came to call on him, these mysterious beings in broad daylight snatched the hat from his head and crumpled it up. They threw stones, too, and kept on throwing them so that all the court was reduced to confusion. Prince Cheung made his escape and went to live in another house, where he prepared a special medicine called sal-kwi-whan (kill-devil-pills), which he offered in prayer. From that time the goblins departed, and now after five or six years no sign of them has reappeared. Prince Cheung, too, is well and strong and free from sickness.

Yi Ryuk.
