It's foggy, and everyone is freaking out. Everyone is covered in a damp cloth, and the smell of rotting flesh is everywhere. The smell is so bad that it's almost impossible to breathe. Everyone runs to get the medicine box back. They've escaped from hell, and now they're back in the city. Everyone's so excited that they can't wait to get back to work. They can smell the rotting flesh again, and they can see that the box was left there by the two men who killed zhao. They don't know how to explain this to imperial court, but they do know that they must have killed each other. It seems like the envoy and the teacher must have been wiped out by the fog as well. They must be the same people who are missing in the county ofjiangning. The teacher has come to investigate the case of the missing, and he's worried that the envoy is killing people because of the foggy fog. He's also worried about the teacher's death, too.
