Il-Geum can't catch a break! Jade of Ice, one of the Three Gems of the Land, hires the Divine Goddesses to have Il-Geum killed for humiliating her in public. The Divine Goddesses instead stage a kidnapping of Il-Geum, dropping him off in front of the cave of the Twin Devils of North and South. He lends a hand to the Twin Devils by reading the book Art of Spiritual Heaven aloud to them. Whoever masters this art has the power to conquer the land! Il-Geum falls asleep and never finishes reading the book, but unaware of that fact, the Twin Devils fly off in haste. Ji-Ro discovers Il-Geum and realizes that Il-Geum has acquired immense power-and now is his only chance to get rid of Il-Geum for good...
