Got it!
Wang Yao thought about a licorice root called Kang wood, which could be used to get rid of the pests. It was a kind of wooden plant as well as licorice root. It grew extremely slowly and could distribute a special smell to drive the pests away. It also had other wonderful effects.
"What are you doing here?!" Someone broke Wang Yao's thoughts. It was Wang Ru, who had a knife one hand and a rooster in the other. It seemed that Wang Ru was going to kill the rooster.
"Sis, are you going to kill the rooster?" asked Wang Yao.
"Yeah, I tried to kill it twice now, but it is still alive! I can't find its artery. Since you're some sort of pharmacist, tell me where its artery is," said Wang Ru.
"You tried to kill it twice and couldn't find the artery?" Wang Yao took a look at the rooster. He seemed to be able to see the pain and despair in its eyes. This was torture, even worse than death.
