Final answer:
The real name of the Lord General in 'The Death Disk' is not clearly provided in the given sources, and may refer to a character or historical figure not fully represented in the provided information.
Step-by-step explanation:
The real name of the Lord General mentioned in the question seems to be tied to two different stories: 'The Tale of Hong Gildong' and Benjamin West's painting 'The Death of General Wolfe'. However, neither source clearly defines a character simply as 'the Lord General'. In 'The Death of General Wolfe', the actual historical figure is General James Wolfe, and in the fictional 'The Tale of Hong Gildong', the character of interest is Hong Gildong. Since the question mentions the 'Death Disk', without further context, it is challenging to provide an exact name for the Lord General. It is likely that there has been some mix-up in the provided story elements or the question itself.
In the text extract about Gil-Dong, the story suggests a proposition to the government to confer upon Gil-Dong a rank to remove the stigma of being a son of a slave. Still, when he comes to the Palace, an assassination is planned, yet he disappears in a cloud. This narrative does not offer a clear answer to the real name of the Lord General. If the student is referring to another literary work or historical event not provided in the information, it may be necessary to revisit the source material for the correct answer.
