Dragon King
Choribdongi did make a water-free pathway underwater, and Wang Janggun met the Dragon King of the East Sea. The Dragon King of the East Sea said that if he tactically retreated in the battle with the Dragon King of the West Sea a few days later, the Dragon King of the West Sea would leap at the joy of finally defeating his adversary. When he leaped in joy, Wang Janggun had to shoot the Dragon King of the West Sea's golden scale beneath his ear.
