The words "blood" and "auction" do not appear together anywhere in the series.
But I didn't give up there. I did a fuzzy search using "blood" and "auction". This will show me where the two words appear even close to each other.
None of the times the two words were even close to each other did the "blood" relate to the "auction".
Here are just two examples:

"I am thinking of having all of you killed," said the officer, "all except the slave, who would make a nice gift for some ranking officer."
"I want her," said Tersius Major.
"To be sure," said the officer, "perhaps we will merely auction her off - sell her naked from a slave block in Cos."
