Final answer:
The excerpts provided do not contain information about the story 'Winged Blackmail.' However, they do give details about various characters such as Gil-Dong, who shows mercy to assassins in one of the unrelated excerpts.
Step-by-step explanation:
There seems to be a mistake as the story mentioned in the student question, "Winged Blackmail," does not align with the content provided which appears to be from various unrelated literary sources.
The correct information pertaining to 'Winged Blackmail' or a similar story is not present within the excerpts provided.
If the student is referring to Gil-Dong's action from the excerpt given, it could be mentioned that at the end of the scenario, Gil-Dong shows mercy to the assassins after foiling their plot, taking away their weapons but sparing their lives under the condition that they never attempt to take another life.
For the other incomplete storylines in the excerpts, there is not enough context to determine an ending action.
Given the mismatch and lack of context, it's recommended that the student provides the correct text or additional details in order for a more accurate and helpful response to be given.
