That's right. They would become mute for no reason.
The doctor could not find any reason.
This made these people anxious, and they never wanted to find trouble again.
However, what terrified them was that the more trouble they caused, the more people became mute. Moreover, this strange illness did not affect the servants, but it was the masters who became mute.
It was only when they realized that doing this at the inn was really too risky that they had no choice but to bring gifts and apologize to the innkeeper that things were settled.
Although it was settled, the innkeeper always conveyed his master's words," This time, I'm teaching you a lesson. I'm just making you mute. As long as you don't cause trouble, you'll be fine after a while. If you continued to cause trouble, it wouldn't be as simple next time!"
As for what it was, no one dared to try.
