Yang Qiuchi, Hong Ling and Yang Tashan sat down. Yang Qiuchi asked Chu Die: Did your family have any diseases before their lifetime?"

"As far as the master said, the offender's health was not very good during his lifetime, and he was relatively weak and often suffered from wind and cold symptoms, so I mostly do the work at home. However, the three children have always been in good health and have never had any serious illness."

"Where are the men you used to be? How are their health?"

Chu Die thought for a while: "It's not bad, there is no special disease."

"Then what are the symptoms they had before they died?" Yang Qiuchi continued to ask.

Recalling the past, the Chudie looked sad and thought for a while before he said slowly: "I married three men, all of whom died within a few years. Before he died, he was full of vomiting and diarrhea. He died after not lasting for two days. At first, I thought it was an accident. Later, I married one to death and the other to death. I also doubted whether I really had a life to defeat my husband. This time, not only did I kill my man, but also my three children..."

The butterfly sobbed and started to cry.

Yang Qiuchi was not in a hurry. When she gradually calmed down, she continued to ask: "What did you three men eat before they died?"

Chu Die said: "The last man I ate rabbit meat dumplings before dying. The first two... it took too long, and I can't remember it."

"Then tell me about this process."

"That day, Bai Qian in the village brought us a few hares, and I took one to stir-fry. I chopped the stuffing up the leftover fields and made rabbit meat dumplings for them to eat. They liked to eat this kind of dumplings the most on weekdays. Because I have always been a vegetarian, I didn't eat them with them. After eating, at night, my husband and three children said that they had stomachache, and then their faces were pale, vomiting and diarrhea, and rolling on them. I quickly went to the village to find a doctor. When I invited the doctor, the four of them were already twitching and were confused. They died one after another until dawn..." After Chu Die said that, tears flowed down again.

"What does the doctor say?" Yang Qiuchi asked.

"The doctor said that he had eaten something unclean, but later the patriarch said that I was poisoning because I was the only one who had nothing to do. They were eating in the same pot with me, but they died."

"Think about it carefully, did the two men in front of you also die after eating hare meat?"

Chudie lowered her head and thought for a while. She shook her head affirmatively: "No, eating hare meat is something I did after I married into Baijia Village. Then our family had never eaten hare meat before."

"What staple food do you eat on weekdays?"

"Rice, noodles, and meat-filled dumplings during festivals."

"What kind of noodles is dumpling skin? Is it fermented rice noodles?" Yang Qiuchi frowned.

"Yes, it turns out that the adults are also good at farm work."

Yang Qiuchi said: "Tell me how do you make rice and flour with rice?"

Chudie talked about the production process in detail. At the end, she asked in confusion: "Is there any problem with this? My mother has taught me how to do this since she was a child. We have eaten for many years and nothing happened."

Yang Qiuchi shook his head and sighed softly: "This is probably the price of ignorance!" He stood up and said: "Okay, Shan'er, we need to go to Baijia Village again. Let's go!"

After leaving the cell, Yang Tashan asked Yang Qiuchi: "Father, why do you still have to go to Baijia Village?"

"I guess there is something wrong with the dumpling skin of the rabbit meat dumpling, which may be due to food poisoning."

Yang Tashan slapped his head: "Yes. Why didn't I expect it?"

Hong Ling smiled and deliberately teased him: "You, when you saw that girl butterfly, your eyes were straight. How could you think of this?"

"How could I do it! I just like it..., hehe, I have never liked this butterfly girl."

"Okay! Your sixth aunt is teasing you!" Yang Qiuchi said with a smile.

The followers had already prepared the horses, and the three of them got on the horses, took Cheng Ziqin and the constables, and the group returned to Baijia Village in a mighty manner.

I found the clan leader to explain my purpose. The clan leader hurriedly led Yang Qiuchi and his group to Chudie's house.

The husband and children of Chuwudi were all dead, and the house was locked on the ground. After opening the door, I found leftover rabbit meat dumplings on the kitchen bowl rack.

Yang Qiuchi personally conducted an inspection, and the results showed that the exotoxin a of yeast fermented rice flour, flour, and flour were detected in the dumpling skin.

Yang Tashan never encountered this kind of bacteria when he followed his father Yang Qiuchi to study forensics, so he didn't understand it.

Yang Qiuchi explained: "Kill Chudie's husband and three children is this kind of poisonous dumpling skin. I just heard Chudie tell her that she had made dumplings and passed by, and I suspected that I had only encountered two cases of this kind before, which is very rare. Since it often occurs in exclusive households, it is often suspected of poisoning and killing cases. In fact, this is a kind of bacterial poisoning. People like Chudie do not have the ability to poison and kill people with bacteria, so it should be an accident."

"Bacterial poisoning? How could this bacteria run into the dumpling skin?" Yang Tashan asked.

"Northwest people usually use fermented rice flour to make dumpling skins, that is, soak corn, millet or other coarse grains in water for more than ten days or one or two months, then wash, grind, filter, precipitate, cool to form powder, and then make dumpling skins. There is no problem with this production process itself, but because Pseudomonas coconut poison is widely distributed in the natural environment, making ground fermented rice flour is very suitable for the growth of this bacteria, so it is easily contaminated by this bacteria. Under appropriate temperature and other conditions, a large amount of highly toxic rice fermented acids and toflavins can be produced, which is highly toxic."

Yang Tashan said: "Don't you have to boil noodles and dumplings in boiling water? Father, haven't you said that high temperature can be disinfected?"

Yang Qiuchi shook his head: "This is not a common bacteria. Whether it is fried or boiled at high temperature, it cannot kill this toxin. Once poisoned, the mortality rate is extremely high. Gastrointestinal symptoms will first appear, and substantial damage to the internal organs will occur within one or two days, and eventually die due to hepatic encephalopathy, toxic encephalopathy or acute renal failure."

Yang Tashan stuck out his tongue: "Then I won't dare to eat dumplings in the future!"

"There's no need to choke off food." Yang Qiuchi smiled, "But we'd better not use fermented rice and flour as dumpling skins, haha."

"Since fermented rice and flour are poisonous, why do so many ordinary people still eat it?"

"So I said, this is the price of ignorance. Since the pollution of this highly toxic bacteria is very accidental and the probability of the occurrence is relatively low, it is often not valued by people. Once poisoned, the whole family often dies. Therefore, it is often mistaken for someone to deliberately poison it."

Yang Tashan said: "Then we have to remind the villagers of Baijia Village that we should pay attention to making fermented rice noodles in the future..."

Yang Qiuchi shook his head and said, "It is not easy to prevent it even if you pay attention. It is best not to eat fermented rice and flour. Okay, let's open the coffin and examine the autopsy to see if the cause of the deceased's death is in line with the situation I said. If so, the case will be solved."

The group came to the tomb of the husband and children of Chudoudi, and opened the coffin and examined the autopsy.

This time, there were no villagers watching. The entire Baijia Village was shrouded in a very dull atmosphere. There was no longer the scene of men and women weaving and children playing in the past. Six people had died in a few days. The people in the yamen came almost every day. Everyone went from the initial novelty to the later fear and then numbness. There were only a few people working in the fields in the village. No one looked at these officers and soldiers going to the cemetery, as if they had nothing to do with them.

The sky was gloomy. As if it was about to rain, Yang Tashan remembered the situation when he saw Qu Mei's body that day, and he became a little depressed.

After the coffin was opened, Yang Qiuchi personally conducted an autopsy. Sure enough, the cause of death was exactly consistent with Yang Qiuchi's previous judgment.

Yang Tashan said again: "Father, this Chudie married three men in succession. According to Chudie, the symptoms before death were similar. Did he die from the fermented rice flour toxin?"

"It should be the land. The two men in front of her have been dead for many years. The body is probably boned and there is no way to test it. Only from the symptoms, they have died of this highly toxic bacteria poisoning. From what the butterfly said in the cell just now, we can know that this method of making dumpling skin was taught by her mother. She has been doing this since she was a child, and nothing happened. This is the accidental nature of poisoning of fermented rice and flour. Some people in the land will eat it all their lives, but some people in the land will die after eating it once. She married the two men in front of her. She also made meat dumplings for them to eat, but she did not eat meat, and she escaped by chance in three poisoning incidents."

Yang Tashan sighed and said, "Although she escaped from the God of Death, she was regarded as the God of Death and had never lived a good life, which can be regarded as a cause and effect."

Yang Qiuchi shook his head and said, "No, this matter has nothing to do with her. It is caused by this ignorant eating habit, and it is an accidental accident. She should not bear any responsibility for it. After returning, she told you, Master Han, to let her go."

"Yes! Father." Yang Tashan bowed.

When they returned to Qingyang Prefecture, Yang Tashan told Cheng Ziqin about the case investigation, and the two reported to the prefect Han together.

Prefect Han now knows that Yang Tashan is the eldest son of Yang Qiuchi, the elder Duke of Zhenguo of the Ming Dynasty. Even if Yang Tashan doesn’t tell the truth about the case, he will say it, Prefect Han dare not say a word. What’s more, Yang Tashan is very sarcastic. Although Prefect Han was confused when he heard it, he still nodded repeatedly to praise Yang Tashan for solving the case as if he was a god, and immediately ordered the acquitted Chudie to be released.

Yang Tashan went to the cell and took Chudie out and told her the truth. Chudie knew that it was the dumpling skin he made, which killed his three husbands and three children. He collapsed weakly and cried bitterly.

Before his release, Yang Tashan had sent someone to inform Bai Yuefeng of Baijia Village. Bai Yuefeng had already been waiting at the yamen gate. Seeing this, he stepped forward and helped the butterfly up.

Chu Die knelt down and kowtowed three times to Yang Tashan, thanking him for hanging high in the mirror, solving the case and returning his innocence.

Yang Tashan smiled bitterly in his heart. If it weren't for his father Yang Qiuchi's actions, he would be unable to handle the case just by his own words.
