Oh dear, does the author that blood is eaten in their country alone as a traditional food? What about the English blood sausage and its French sibling, the boudin noir? Or the Italian sanguinaccio? And that to name the ones I’m aware of, but I bet there are similar dishes in other countries too. And to be honest, I would have understood that reaction if the dish was something akin to Roman pagliata.
Anyway, what did Dragon King want to achieve by trolling the humans like that? 🤣
