Tradition says that this was all in fulfillment of a prophecy which was given in the form of an enigma. A Chinese merchant bought a mirror of a Sil-la man and in the mirror could be seen these words: “Between three waters—God sends his son to Chin and Ma—First seize a hen and then a duck—in the year Ki-ja two dragons will arise, one in a green forest and one east of black metal.” The merchant presented it to Kung-ye who prized it highly and sought everywhere for the solution of the riddle. At last the scholar Song Han-hong solved it for him as follows. “The Chin and Ma mean Chin-han and Ma-han. The hen is Kye-rim (Sil-la). The duck is the Am-nok (duck-blue) River. The green forest is pine tree or Song-do (Pine Tree Capital) and black metal is Ch‘ŭl-wŭn (Ch‘ŭl is metal). So a king in Song-do must arise (Wang-gön) and a king in Ch‘ŭl-wŭn must fall (Kung-ye).” Wang-gön began by bringing to summary justice the creatures of Kung-ye who seconded him in his cruelty; some of them were killed and some were imprisoned. Everywhere the people gave themselves up to festivities and rejoicings. But the ambitious general, Whan Son-gil, took advantage of the unsettled state of affairs to raise an insurrection. Entering the palace with a band of desperadoes he suddenly entered the presence of Wang-gön who was without a guard. The King rose from his seat, and looking the traitor in the face said “I am not King by my own desire or request. You all made me King. It was heaven’s ordinance and you cannot kill me. Approach and try.” The traitor thought that the King had a strong guard secreted near by and turning fled from the palace. He was caught and beheaded.
