Final answer:
In the story, Gil-Dong is targeted by assassins but is not in his room when they arrive. A storm and a miraculous landscape change trap the assassins, who are then confronted by Gil-Dong. He spares their lives on the condition they never try to kill again.
Step-by-step explanation:
The question pertains to the character Gil-Dong, who, upon hearing a crow caw three times at night, suspects an ill omen. Assassins break into his room intending to kill him, but the boy is not present. In a chaotic scene, the assassins end up injuring each other and killing their guide, an old woman.
In this moment of confusion, they find themselves trapped in an environment that has transformed into a mountainous landscape with a storm raging around them. Unable to escape, they are saved by the arrival of the boy they were after, Gil-Dong, who arrives playing a flute while riding a donkey. Gil-Dong disarms them and spares their lives on the condition that they never attempt to take a life again, threatening them with instant death should they break this vow.
