I am writing a story where a man makes a treasure map written in his own blood. I know that this idea was in King Solomon’s mines, but I would like to develop that idea or re-use it in my story. It just sounds wicked cool to have something like this in a book. What conditions might he be placed in to use his own blood as ink.
Please don’t answer, because he has no ink. I think that is kind of obvious.
Thanks for the suggestions.
the time that the man lived was about 1700
