Soon Jiang Sisi brought the medicine jar and bag.

She put things on the table.

Jiang Fengnian opened the paper bag in public and revealed the medicinal materials inside.

Except Jiang Weiwei and a Tao, none of the people present knew medical theory and could not confirm whether the medicinal materials were poisonous.

But both Jiang Weiwei and a Tao are suspects. For the sake of fairness, they can't identify the medicinal materials.

It was suggested that Dr. Li be invited.

Gu Fei's foot journey is relatively fast. He took the job on his own initiative.

Dr. Li lives in the next village. It takes at least more than an hour to go back and forth.

Big black ran so fast that it took only half an hour to carry Doctor Li to Yunshan village. Gu Fei was afraid that the two people were too heavy for big black to run, so he didn't sit on the donkey's back, but ran behind. But even so, he didn't get rid of big black and followed big black steadily.

When he reached his destination, Gu Fei helped Doctor Li down and ran into the house quickly.

When they saw Doctor Li coming, they all gave way.

Dr. Li didn't talk nonsense. First, he checked Jiang Baoyuan's body to make sure it was poisoned and died, and then helped check the medicinal materials and drug residues.

The crowd stared at him without blinking and waited quietly for the result.

Sun Ergang has been wiping his sweat and appears extremely nervous.

It took a long time for Doctor Li to speak.

"These are herbs for treating lung disease and cough. There is no problem."

Tao immediately said, "you heard that. There is no problem with the medicine. We are wronged!"

Sun Ergang was unconvinced: "there is no problem with this package of medicinal materials. There is no guarantee that the other two packages of medicinal materials are also OK. Maybe you poisoned only one package of medicinal materials?"

"You!" Tao stamped his feet in anger.

Jiang slightly raised his hand and motioned to Tao to calm down.

Jiang Fengnian asked Dr. Li to go on.

Doctor Li pointed to the drug residue in the medicine jar and said, "the drug residue in this jar is poisonous. My knowledge is limited. I can only roughly estimate that it is a kind of snake venom. It should be refined from the gall of a poisonous snake."

As soon as he said this, everyone's eyes fell on the medicine jar.

Jiang Fengnian directly poured all the drug residues in the medicine jar onto the table.

The wet dregs are laid flat and look no different from ordinary dregs.

Dr. Li tried with a silver needle, and the silver needle suddenly became black.

Jiang Fengnian looked at the silver needle, then looked at Jiang Sisi and asked, "who made this pot of soup?"

Jiang Sisi seemed to have never thought that the problem was actually caused by this pot of soup medicine. She subconsciously looked at her sister, and then hesitated and said, "this medicine was originally made by my mother. Later, my brother suddenly woke up and shouted for his mother, so my mother ran to look after my brother, and my eldest sister and I stayed in the kitchen to look after the soup medicine."

"In other words, this pot of medicine was made by your mother and daughter? Others have not passed? "

Jiang Sisi nodded first, then seemed to think of something, and suddenly shook his head again.

Jiang Fengnian frowned: "you've confused me by nodding and shaking your head. What do you mean?"

"When my eldest sister and I were looking after the soup medicine, my eldest brother-in-law suddenly came. He said he brought me a good-looking ruler head and asked my eldest sister to bring it to me, so I went to the house with my eldest sister to look at the ruler head and asked my eldest sister to stay in the kitchen to help look after the soup medicine."

After saying this, everyone looked at sun Ergang in unison.

Sun Ergang's legs trembled and he almost knelt down.

Fortunately, he grabbed the last bit of reason, barely remained calm, and explained, "I looked after the soup for a while, but I didn't do anything!"

Jiang Weiwei asked, "who can prove that you didn't do anything during the time you were looking after the soup?"

Sun Ergang couldn't answer.

Jiang Weiwei asked, "no one can testify for you, right?"

Sun Ergang is really in a hurry.

He couldn't help looking at his daughter-in-law and wanted her to help make a certificate.

When Jiang Meimei saw him looking at herself, her eyes were full of the meaning of asking for help.

She understood what he meant. He wanted her to help make false evidence.

She instinctively wanted to refuse, but when she thought that she was still pregnant with his child, the child could not be born without a father. When she refused, she swallowed it again.

My brother is dead. People can't come back to life after death, but those who live have to live.

Jiang Meimei held back her guilt for her brother and said in a trembling voice, "I can testify to my husband."

Sun Ergang was happy and was about to speak when he heard Jiang Sisi speak first.

"Sister, what are you talking about? You've been with me this evening. How can you know what your brother-in-law did in the kitchen? "

Jiang Meimei choked.

She only focused on her husband's affairs and forgot about it.

Sun Ergang's joy, which had not yet completely appeared in his heart, was extinguished in an instant.

Jiang Wei smiled and said, "brother-in-law Tang, you can even find someone to do perjury in order to clear your suspicion?"

Sun Ergang hurriedly explained, "I didn't do it! I am innocent! "

Just now, everyone had only two or three points of doubt about him, but he asked someone to give false testimony, which made everyone's suspicion index of him instantly rise to 89 points.

If he doesn't feel guilty, why does he have to find someone to give false testimony?!

Jiang Fengnian stared at sun Ergang for a moment and said, "a mu, take someone to search sun Ergang's room."

Jiang Mu asked the two villagers to go together.

Then Jiang Fengnian said, "ah Yue, you search sun Ergang."

Jiang Yue strode forward to search sun Ergang.

Sun Ergang immediately dodged and shouted hurriedly, "what do you want to do? I'm not from your village. You have no right to do this to me. Get out! "

His resistance made people feel more suspicious.

Jiang Yue couldn't subdue sun Ergang alone. Gu Fei came forward to help. Three or two times, he pressed sun Ergang, who was struggling violently, on the floor and couldn't move any more.

Jiang Yue began to search sun Ergang. He searched very carefully, even the soles of his shoes.

Jiang Meimei was so anxious that she wanted to stop her, but she was stopped by Jiang Sisi.

Jiang Sisi said, "he may be the real murderer of his brother. We must find out!"

Jiang Meimei kept shaking her head: "he didn't do it. He must not have done it. You let him go!"

At this time, Jiang Weiwei came to the table. She first looked at the medicine residue, then picked up the medicine jar and checked it carefully.

The medicine jar is black from inside to outside, with uneven surface and many small depressions similar to honeycomb.

With the light of the oil lamp on the table, Jiang slightly noticed that there was a little white powder on the edge of the medicine jar. The powder is stuck in the gap between the depressions. Unless it is washed with clean water, it is difficult to clean it. Because it is only a little, it is difficult to find it if you don't look carefully.

She called the village head and Doctor Li, pointed to the white powder on the edge of the medicine can and motioned them to see it by themselves.
