According to my knowledge of online literature, the main body of a novel is usually the main plot and content of the story, which is generally summarized at the beginning or end of the novel. The word " big steel " referred to the number of words in a novel, which was usually calculated in thousands of words. Therefore, the meaning of 10,000 plus 1,000 steel bars in the main body of the novel could be understood as the main body of the novel had a total of 10,000 words, and the part with the most words was 1,000 steel bars.
