Thousand-faced fox is good at inquiring about news, but he has no experience in investigating cases. Thinking of what Zhu Qing said, she couldn't help asking: "Madam, Prefect Bian said that Qin Sanhuai was using arsenic in the dish, but he didn't say which dish it was."

Qingshu shook his head and said, "I don't think it's arsenic, they are likely to be food poisoning."

The Thousand Years Fox actually thought it was food poisoning, but she still pretended not to know.

Qingshu answered her questions and said, "If the arsenic is ingested, even if eaten in small amounts, it will easily lead to death. But only Liu Xiucai died, and the other five were just diarrhea and convulsive. This is different from what is rumored outside."

"But the people who attended the poetry meeting are from good families, they will definitely not invite a chef to cook. The chef who holds the spoon knows which foods will be incompatible with each other. For example, crabs cannot be eaten with pumpkins, and turtles cannot be eaten with celery."

Thousand-faced fox said with some emotion: "Madam, what do you mean, are there any problems with the chef?"

Qingshu said: "This is just my guess, and it may be the other people in the kitchen. But no matter which kind of poisoned person is, he must have a deep feud with one of them, otherwise he would not have used such intense means."

So they must check this matter carefully.

The Thousand-faced Fox nodded.

But when he went to bed at night, Qingshu suddenly asked, "Will the Feiyuwei people help others investigate the case before?"

The Thousand Years Fox uh whispered: "It didn't happen before, but isn't it changed now? Now many of them have changed and cannot be compared with old examples."

Qingshu thought about it and thought it was. Now she just hopes that the case is not too complicated, otherwise it would be shameless if she did it for the first time.

The next day, the group went to Feiyuwei. The responsible person of Yongyang Feiyuweiwei was Tang Wenru, and he was a middle-aged man in his thirties.

He was surprised to see Qingshu, but he still greeted him.

Qingshu was his immediate boss, so he didn't exchange greetings, but went straight to the topic: "I came here mainly to poison several scholars for Qin Sanhuai."

Tang Wenru said: "Sir, this case is not handled by us."

"I know it's not yours. Now someone has sued Feiyuwei and said that the prefect Bian is disregarding human life and randomly judging the case, so the commander sent me to investigate the matter."

Tang Wenru was stunned and came to his senses and said to Qingshu: "Sir, investigating the case is the affairs of the Ministry of Justice and is not within our jurisdiction."

The Thousand-faced Fox said impatiently: "Since the commander sent my master to investigate this matter, they all reported it to the emperor."

This is very clear. If the Ministry of Justice comes to find fault and says that they have no reason or position to overstep their authority, after all, no matter how powerful they are, they are, they are better than the emperor.

Tang Wenru felt relieved when he heard this. As long as the emperor agreed, he would not say a prefect, even the governor would be able to check it out.

“Where is the file?”

Tang Wenru had no file in his hand, but he said, "Sir, please take a break. I will send it to you in an hour."

"Don't let people know that we're investigating this matter for now."

Tang Wenru naturally knew that if the prefect Bian knew that their Feiyuwei had secretly investigated the matter, they might interfere with it so that they could not successfully investigate the case.

An hour later, Qingshu obtained Qin Sanhuai's file. However, the ink of this file was very new, and you will know that it was just copied after reading it. But it was normal. It was impossible to take out the signature and seal of the yamen, and it was a great responsibility to lose it.

This file is very detailed, recording the detailed process of the entire case, including Qin Sanhuai's confession of poisoning, and Qin Sanhuai's confession was attached.

According to the confession, Qin Sanhuai explained that he was very talented and had a good reputation, Liu Xiucai and others bullied themselves by relying on their family background. They would not get out of order and then pour arsenic into the vegetables.

After reading the file, Qing Shu asked, "Have you read the case file?"

Seeing him nodding, Qingshu said, "Qin Sanhuai confessed that he poisoned and used arsenic, but there was no arsenic in his confession, saying which medicine shop he bought it from and which dish the arsenic was placed in. Also, how did he put the poison into the dish so many people in the kitchen and how did he not find it?"

From this confession, we can see that the prefect Bian is a foolish official, and the case of life-threatening death was so confusing.

Tang Wenru asked, "How is Lord Lin going to investigate this case?"

Qingshu's opinion was to meet Qin Sanhuai and asked him to describe the situation on that day in detail, especially the process of eating, such as how many dishes there were in total, where and how many dishes he didn't eat.

Tang Wenru hesitated and asked, "Sir, do you want to interrogate Qin Sanhuai in person?"

Qingshu shook his head and said, "No, if I want to go, it will be too much of a deal. Just let A Qian follow you."

She has analyzed the case with Qianfa Fox. She and Qianfa Fox can go either.

After pausing, she said again: "By the way, let me see the resume of this prefect Bian and the situation in office over the years."

Such a major case was sentenced so confusingly by him. Qingshu felt that the case he handled was likely to have many unjust, false and wrong cases.

Tang Wenru hesitated and said, "Prince Bian was transferred to Yongyang at the beginning of last year. He had previously worked in Luzhou, Shu. We don't know much about his situation there."

Qingshu said lightly: "Then let's sort out the case he has handled over the past year and show it to me."

The official Bian Magistrate Bian made random judgments, but Yongyang Feiyuwei, as the supervisory authority, did nothing. The Feiyuwei is still like this. You can imagine that other places want to have a clear and bright position in the world!

The Thousand-Faced Fox followed Tang Wenru out at night, and it was already midnight when he came back: "Sir, Qin Sanhuai said he was not poisoned at all, he was scolded."

After saying that, she handed a few pieces of paper to Qingshu, and in order to prevent her from missing, she wrote down everything Qin Sanhuai said. Because this incident left her in a cage, Qin Sanhuai still remembered the situation at that time.

After reading this information, Qingshu said, "Qin Sanhuai said that he didn't eat two dishes, one was braised carp and the other was sour bamboo shoots and chicken."

"That's what he said, why, is there any problem?"

Qingshu thought for a while and said, "Carp and chicken are incompatible."

Qianmenghu said, "There is a problem with the chef, otherwise how could he make carp and chicken at the same time?"

Qingshu shook his head and said, "Even if these two are eaten at the same time, if you don't eat too much, your stomach will not cause death."

After pausing, Qingshu suddenly flashed his mind and said, "I remember eating carp and licorice together will produce strong toxicity. It will not only cause abdominal pain but also convulsions. If you don't receive timely treatment, you will die. Looking at Qin Sanhuai's description of several people above, it is very similar to what I saw in the book."

"Licorice? How to eat licorice in vegetables? And it's a big goal and it's easy to find out?"

Qingshu said: "It can be ground into powder and mixed with spices and sprinkled in the dish. Braised carp tastes strong, unless they have a sensitive tongue, they will not be able to eat it."

"Of course, it's just my guess. After checking, I will know if my guess is correct."
