"Master Gao, I wonder if Mr. Wu Zuo can come out for a moment. I need Mr. Wu Zuo to testify for me about some medical knowledge."

Gao Zheng thought for a moment and nodded, "Invite Mr. Wu Zuo over."

The old woman lowered her head and had a bad feeling in her heart.

Mr. Wuzuo came out quickly and saluted each prince under pressure.

Yun Ning called out very politely, "Mr. Wu Zuo."

"The grassroots are here."

Wu Zuo responded.

"Excuse me, Mr. Wuzuo, how much do you know about medicinal materials like Yongshan?" Yun Ning asked.

Mr. Wu Zuo thought for a moment and said, "The common people only know a little bit about it."

Yun Ning continued: "There are three types of poisons that can be made from medicinal materials such as Yongshan. The first is to seal the throat upon seeing blood, the second is to be sad at the end of the world, and the third is to be bitter noodles. Is that correct?"

Wu Zuo's understanding of Yun Ning has reached a new level, because he only knows two kinds of poisons.

"It's exactly what County Master Yun said."

"Does Mr. Wuzuo know how long it takes for these three poisons to take effect?"

"People don't know much about the Late Grass in the Sad Realm, but the other two are poisonous immediately."

After finishing speaking, he added: "And the poison that all the shopkeepers have been exposed to is Kumian Powder."

This testimony made the people present look at the old woman in a much weirder way.

Ye Xiaohuai said at this time, "That means that no matter whether County Master Yun went to find the housekeeper that night, his death cannot be proved to be the fault of County Master Yun."

The old woman's face changed.

Gao Zheng said "hmm" and nodded, "What the fifth prince said makes sense."

After he finished speaking, he looked at the young woman again, "Has County Master Yun ever looked for your husband?"

The young woman thought for a moment and shook her head, "No."

Gao Zheng asked several family members of the shopkeepers as usual, but never got the same explanation as the old woman.

He frowned, this matter seemed to be developing in a strange direction.

At this time, a government servant walked over from outside and raised his hand to Gao Zheng, "Sir, there is a man outside who claims to be the servant of Nanshan Hall, saying that he wants to expose Lord Yun County."

There was an uproar in the venue. They had just thought that they had wronged the head of the Yun family, but someone from Nanshan Hall came out!

Nanshan Hall is County Lord Yun's own person, how could he expose her?

When the government officials brought the person up, they discovered that it was Fu Yong's former drug boy.

At that time, at the gate of Nanshan Hall, he expressed his gratitude to his master for taking him in, but he didn't expect that just a short time later, he would come out to testify against his master.

Yun Ning looked at the medicine boy coldly. The medicine boy only glanced at Yun Ning hastily when he entered the door, but quickly looked away, with a guilty look in his eyes.

Gao Zheng frowned and asked, "Who is in the audience?"

The medicine boy hesitated and said, "The grassman's name is Twelve. He was originally from the Medical Herb Hall, but later he was sent to Nanshan Hall by County Master Yun to work here."

"County Master Yun, is what he said true?" Gao Zheng asked.

The curve of Yun Ning's mouth was a little sarcastic, "It's true."

"Okay." Gao Zheng nodded and turned to look at Twelve, "What do you want to expose?"

Twelve seemed to be struggling a lot, but finally "made up his mind" and said, "I want to expose that County Master Yun once made bitter noodle powder in Nanshan Hall!"

As he spoke, he secretly glanced at the old woman, who gave him an affirmative look.
