"Well, a sheep died before that person. There might be other animals involved," Wang Yao calmly said.
"Really?" Professor Wu was surprised. He didn't expect animals were involved. "What do you mean?"
"The first person who died of this disease was Chen Jiagui. He was a notorious old bachelor in our village. Before he got sick, he ate the meat of that crazy sheep," Wang Yao said.
"Crazy sheep?" Professor Wu asked.
"Yes, the crazy sheep had been to a few places before it went crazy," Wang Yao said.
"Was it those so-called places of death?" Professor Wu asked. He had learned about those places in a report.
"Yes," Wang Yao said.
"Well..." Professor Wu wanted to remind Wang Yao of the relevance regarding what he was talking about.
"By the way, this is the decoction's formula," Wang Yao said as he took out a piece of paper.
"Look, I promise I won't tell anyone about this formula," Professor Wu said before taking the formula.
