After figuring out the ins and outs of Qin Tiezi's case, Xu Chu took the second case file and looked at it.

Because when she was thinking about it, Xiao Qinglang had already finished reading the case file about Peng Ning's murder. He has never forgotten it, and he looks at the case files and the files everywhere at a glance, so he is naturally much faster than Xu Chu.

After seeing the girl test his throat with a silver needle, he found that the silver needle had turned black, and then concluded that Peng Ning's husband Peng Yiguang had died of arsenic, Xu Chu couldn't help frowning.

She didn't speak, but went directly to the testimony of the Peng family, and saw that it was written that the deceased Peng Yiguang died suddenly after returning to the room after dinner. It is said that before he died, he said that he had a bad headache, but before Peng Ning asked people to ask for a doctor, he died.

Later, after an examination, it was said that he died of poisoning. In contact with him, he eats all day at the same table with his family, and only at dinner time he asked Peng Ning to make a bowl of peanut paste for him, which is untouched by others.

That is, if he really died of poisoning, then the problem must be with the bowl of peanut paste.

Later, the government found out that the peanut paste from grinding to brewing only passed through Peng Ning's hands. In this way, she naturally became the most likely murderer.

However, because one is that it is impossible to find out where the arsenic under Peng Ning's family came from, and the other is that Peng Ning's family also refused to admit to poisoning her husband, and even almost committed suicide in the lobby to prove her innocence. Therefore, despite several twists and turns, this case has still not been settled.

Although Qian County's official position is low, he has always been strict in the case. In his judgment of the case, he advocated that there is no doubt about the guilt, and if there is no conclusive evidence, he will never judge anyone's crime based on feelings and a few accusations.

Although this is the case, after Peng Ning's family was kicked out of the Peng family, she was spurned every day, and she also went to the yamen several times to cry out for injustice. However, the rumors are like tigers, hurting people invisibly, unless the case is solved, the yamen will not be able to make decisions for her.

"My lord, I don't know if I did the autopsy for Peng Yiguang, but I am still in this county?" Xu Chu put down the file and asked in a solemn voice.

Qian County Ling nodded and said, "Naturally, he was born as a butcher, but because he caused some trouble, the shop was closed." So over the years, he has been helping people perform autopsies and collect corpses for a living. ”

Xiao Qinglang saw that Xu Chu was interested in the servant, so he couldn't help but smile and handed over a file that he was tapping his fingers on.

He opened his mouth and said, "That guy surnamed Feng is a fierce man, and he once seriously injured an old woman who bought meat because of a quarrel. Later, the old woman's family sued, and he cashed out the shop for personal reasons, and compensated the other party's family, so that the old woman's family withdrew the case. After his family went bankrupt, he had no other way to go, and he didn't want to do coolies, so he did a job. ”

After speaking, he smiled faintly, as if recalling what Xu Chu used to be. At the beginning, when she first met, she was still very cold to herself, and even after guessing her identity, she did not see her attitude ease.

At that time, he once felt that in her eyes, he was probably not as important as a corpse. At the very least, when she saw the corpse, she would have emotional ups and downs in her eyes, and even when she dissected the corpse, she would show a hint of excitement about trying it.

If he can think of this, Xu Chu can naturally do it too. In just a few words, she understood, probably that Feng Qiaozuo, like her, had done things that everyone avoided for her livelihood.

After all, in addition to being able to check the corpses in the murder case under the name of the yamen, he can also earn some money by helping some beheaded prisoners collect the corpses. If you are lucky, you can also help the descendants of each family or the corpse to collect the body, and then get a reward.

Of course, if there is a bad mind, it will also do some tricks because ordinary people can't understand the autopsy process. Either to cover up the traces on the corpse, or to deliberately damage the corpse, or even to forge a fake autopsy sheet to make a profit. If this is the case, then his so-called forced livelihood is a different matter.

After Xu Chu looked through the file made by Feng Yan, he knew a little bit about him. This person has a violent temperament and is extremely greedy for money, and has even extorted money by helping people collect corpses. It's just that because he has conducted several autopsies and has indeed solved key clues for the Yamen, he is also outstanding in the various counties of the state.

Now, except for the old man who once helped Qin Tiezi steam the bones for an autopsy and had not performed an autopsy for many years, Feng Zuo is the only one in this county who is a professional. In this way, his autopsy list naturally carries a lot of weight.

"This Feng Cheng is made," Xu Chu muttered.

"Is there anything wrong?"

Xu Chu shook his head, sighed and said, "Normally, testing for poisoning with a silver needle is the same as testing with glutinous rice, which is very inaccurate. To be precise, the silver needle does turn black when it encounters arsenic, but in addition to arsenic, it also turns black when it encounters sulfur-containing food. ”

She didn't care what Xiao Qinglang could understand, so she just continued, "For example, fish, meat, eggs, peanuts, dried fruits, etc., if you test it with a silver needle, it will also turn it black." ”

Although there are many works that are still using this as the basis for whether it is arsenic poisoning, there are many works in Yunzhou City, and this method has long been abandoned. And since the old man of this county can learn the method of steaming bones in Yunzhou City for autopsy, he must have heard of the method of Yunzhou Yamen abandoning the silver needle drug test. And Feng Yanzuo, who is the autopsy in the same county, should not turn a deaf ear to this news. ”

Although it was just a guess, it inevitably increased the suspicion in Xu Chu's heart.

The method of testing drugs with silver needles has existed since ancient times, and even in the palace, silver bowls and spoons are often used for meals, which may not be without the idea of testing drugs. I heard that in the early years of the emperor, there were several times when the imperial dining room put soup and rice into a silver plate, and the silver plate was slightly dim, and then many people in the harem were implicated in prison.

Later, someone in the hospital found out that the food that was sealed at that time was not poisonous. In the end, the incident was not resolved, although it was recorded in the inner court, but in order to cover up the fact that the emperor was wrongly imprisoned, those things were not publicized.

Now it seems that, as Xu Chu said, it is really not accurate to test the poison with a silver needle.

Qian Xianling was stunned for a moment, and hesitated, "Xia Guan has never heard of this statement, I wonder if the prince and the girl may be sure that the silver needle will not only turn black when it encounters arsenic, but also turn black when it encounters peanut paste?" ”

Xiao Qinglang didn't bother with him, and directly sent someone to prepare a bowl of peanut paste. Then, I asked Aunt Chu for a silver needle, and the silver needle penetrated into the peanut paste slightly, and in an instant, it became dull and colorless, and after a few breaths, it was dyed with a layer of black.

At this point, what Xu Chu said is true or false, and there is no need to refute it.

Qian Xianling was dumbfounded, and his heart was secretly surprised. However, if this is the case, then the theory that Peng Yiguang died of arsenic poisoning cannot be established. After all, the last thing the deceased ate before his death was peanut paste, and it was that bowl of peanut paste that became evidence for the Peng family's accusation of Peng Ning's poisoning.

In addition, looking at the autopsy list, there is no statement of the change in the body on the second day. Moreover, in the case file of Lord Qian's trial and the petition filed by Peng's family several times, there was no mention of whether Peng Yiguang had any shocking changes during the mortuary funeral in the house. ”

Xiao Qinglang hummed softly, and when he saw that Qian County's order seemed to be puzzled, he said, "This king once met a person who died of arsenic poisoning in the capital, and when he saw the corpse again after a day and a night, he saw that he was covered with blue-black blisters all over his body. And the eyes are bulging, the tongue is full of small blisters, the lips are cracked, the ears are swollen, the abdomen is swollen, and the nails are blue and black. Its appearance is very terrifying. ”

Hearing him say this, Qian Xianling suddenly realized, "Before the Peng family buries Peng Yiguang, they will definitely take one last look, and then cover the coffin and nail it." And during the three-day mortuary, none of them noticed anything unusual, that is, "

He exclaimed again and again, and when he looked at Xu Chu, he asked with a serious face, "The girl must know this as a servant?" ”

Xu Chu nodded, "If it's another poison, it may be excused as unrecognizable." However, the changes in the corpse caused by arsenic and wild arrowroot poison are very common. Generally speaking, a little experienced man, after testing the poison with a silver needle, will wait for the corpse to be parked for a day and night, and if there is a change, it will be completely confirmed by the fact that the silver needle has turned black. ”

So far, just a few sentences have completely pointed out the inappropriateness of Feng Cheng's actions. If it weren't for the outspoken work, I am afraid that I would never bother to overturn the autopsy conclusion of Feng Chengzuo, who is highly valued by the government.

Seeing this, Xiao Qinglang stretched out his hand to take the file surnamed Feng Chengzuo, and said to Qian Chengzuo, who was waiting at the next head, "It's getting late today, and I won't wait until tomorrow to re-examine the autopsy." You first have people send all the autopsy sheets that Feng Cheng has recorded over the years, as well as the case files he has intervened in. ”

When the Qian County Commander heard this, he hurriedly went out in person and ordered him to go down. Fortunately, since he took office, the various files stored in the yamen have been reclassified, and in order to prevent re-examination, the cases of the two people who had examined and seen the corpses were placed separately. So, it didn't take much time to find it at this time.

Only half an hour later, I saw the official send a stack of files. From wounding cases to accidental deaths, or homicide cases, it is all complete.

Although Xiao Qinglang is not proficient in the way of autopsy, he can come all the way with Xu Chu, and he has helped her fill out the autopsy form many times, so he will not really understand anything at this time.

Two years ago, he examined the body of an unknown man who had been dead for two days in the mountains. Because the corpse was covered with small blisters, its eyes were protruding, and small blisters were protruding on its tongue, it was determined that it was wild arrowroot. Xiao Qinglang turned his head to look at Xu Chu and frowned, "Feng Qizuo can test the wild kudzu poison, how can he not know the inspection method of arsenic poisoning?" It seems that there are twists and turns in this matter. ”

In fact, the wild kudzu poison is the poison of the hook kiss that Xu Chu helped the son of the Wei family to solve before, which is the legendary broken intestine grass. This poison is less common than arsenic. Therefore, Xiao Qinglang's suspicion of Feng Yanzuo is not unreasonable.
