Why can't Douro's sausage be eaten?

You can eat it, but people don't want to eat it because the spell is obscene. Sausage in Douro mainland refers to "reduced sausage", which is a skill of Oscar, the soul teacher of the first food department. It is made by thoughts, and can be eaten by oneself, which can restore the soul and physical strength. However, because Oscar needs to shout out corresponding spells when making recovery sausages, such as "I have a big sausage" and "I have a small sausage", these spells are too obscene, easy to create fantasies in the listener's ears, and easy to make people feel uncomfortable, so people are reluctant to eat them.
