Lu Hui, who was locked in the west wing, didn't know what was going on in the guest hall, and was still thinking about a way out on his own. While thinking about it, he suddenly saw Lu Yan walk in.

"Hey, I asked for a few dozen taels of silver from this world, that's the money to drink flower wine!" It's the familiar opening again.

"Isn't the dinner party about to start, what are you doing here?" Midori asked, puzzled.

"The dinner party can't be eaten, it's all dead!" Lu Han sighed regretfully.

"Dead people? What's going on? Green Hui was also curious.

"It's just a cook, it seems that he died of arsenic poisoning," Lu Yan took a long time to roughly tell Lu Hui what had just happened.

After listening to his words, Green Hui probably figured it out, and preliminarily judged that this was a vitamin C shrimp poisoning incident that modern people almost thought was common sense, or a special case enhanced version (because the examples of vitamin C plus shrimp deaths are actually rare), but for these ancients, maybe they don't know what the cause is. Moreover, this is not a common food poisoning, and certain conditions must be met to occur.

Shrimp contains pentavalent arsenic, which is harmless to humans, and fruits contain vitamin C, and when the two are eaten together, pentavalent arsenic will be reduced to trivalent arsenic, which is commonly known as "arsenic". However, this process of transformation requires a large amount of vitamin C to participate, and only when a large amount of shrimp is eaten and a large amount of vitamin C is ingested at the same time, it can lead to "arsenic poisoning". As for this amount, Green Hui doesn't know very well, but it is almost impossible for a normal person to achieve this lethal amount.

According to Lu Han's description, although Master Ling ate a lot of oranges and shrimp, and poured lemon juice, he was far from meeting the conditions of "arsenic poisoning", and his symptoms were indeed too similar to arsenic poisoning. If it turns out that it is really arsenic poisoning, then in addition to the arsenic produced by vitamin C plus shrimp, Master Ling must have ingested arsenic from other sources!

According to the description of the apprentice, Green Hui locked the object of suspicion on those oranges, because in addition to oranges, what Master Ling ate in the past two days will be dishes that the guests at the conference will also eat, and these dishes will be tested for poison by Gongsun Li one by one, so there is no way to start poisoning. Oranges, on the other hand, do not need to be tested and are the best carriers of poison. As long as a caring person does a little bit of hands and feet on each orange and adds a little trace of arsenic, the person concerned will not notice it when he eats it, which is why the primary school apprentice has nothing to do after eating an orange, and he is sure that the orange is fine. However, as long as you eat more oranges, arsenic will be deposited in the body, and arsenic is difficult to excrete from the body, which will slowly evolve into chronic arsenic poisoning. Combined with the arsenic produced when eating large quantities of shrimp and oranges, the amount of arsenic has reached the lowest possible lethal dose, and poisoning death is an inevitable result.

Therefore, the arsenic produced by the food only acts as a catalyst, but it is likely to become a shield for people with intentions who want to poison Master Ling and thus blame Gongsun Li Zai. Even if the autopsy proves that Master Ling did die of arsenic poisoning, that person can put all the blame on the "accident" of food poisoning. And those so-called oranges with arsenic, I believe that they have already destroyed their bodies, and the apprentices have "proven" that oranges are okay, and I believe that they will not suspect oranges. And Gongsun Li is different. Even if he wasn't the poisoner, it happened in his place, and he had to give everyone an account. However, this matter was already very tangled, and if Gongsun Li could not judge the case in a short time, his reputation would be ruined.

Green Hui could almost conclude that this poisoning case was man-made, and it was obvious that someone with a heart was slowly guiding Master Ling to "death by poison". And this man makes good use of the self-doubt of the crowd, and in the case of plausibility, it is easy to deny what he is sure of. It was in this way that they saw that Gongsun Li no longer dared to let people try the shrimp.

What Lu Hui is thinking now is that even if they wait for Master Ling's family to acquiesce in the autopsy, the final result only shows that this is "arsenic poisoning", but how did the "arsenic" come about, whether it comes from lemon shrimp, oranges, or both, there is no way to verify at all.

In fact, the key is in that plate of shrimp, that plate of shrimp is absolutely no problem, this green club can be 100% sure. Moreover, Gongsun Li tested it with a silver needle again.

Although the use of silver needles to detect poison in ancient times is not very scientific, some poisons can still be detected in some cases, especially "arsenic". The scientific name of "arsenic" is **********, in ancient times, due to the backward production technology, the arsenic made was accompanied by a small amount of sulfur and sulfide, once in contact with the silver needle, the sulfur and silver underwent a chemical reaction, and a layer of black "sulfide" was generated on the surface of the silver needle.

It's just that no one dares to touch that plate of shrimp now, because everyone is not sure if there is a problem with it, silver needle drug testing can cause accidents, and there is only one human life, and no one will try it casually. That's what the people with the heart are taking advantage of.

But why didn't they think of using livestock to test for poison? Perhaps, Gongsun Li thinks that using livestock to test poison is a manifestation of heart deficiency, because if you don't have a weak heart, how can you let livestock test poison, and you can try it yourself. There are too many "caring people" here, and any small move by Gongsun Li will be infinitely magnified. At this cusp, he didn't dare to act rashly.

In a word, it is really a simple and tangled "arsenic poisoning" incident! But the natural suspicion is enough to complicate things.

"Hey, what are you thinking?" Seeing that Lu Hui fell into deep thought, Lu Han shook his hand in front of her!

"Nothing!" Green Club came back to its senses.

"I think you should take advantage of the chaos to escape, now Gongsun Li is confused and entangled in the poisoning incident, he won't find out that you escaped, I can help you!" Lu Yan seemed serious, but in fact said casually.

Green Hui gave him a blank look, this person would really cause trouble. If she can leave in this way, then she will also look down on Gongsun Li Zai.

"You go and tell Gongsun Li that I can help him, let him let me out, and then lock me up after the case is over!" After thinking about it, Green Hui decided to rescue these tangled people.

Lu Yanhu looked at her suspiciously, not like she was joking. Although he didn't know what she wanted to do, he didn't ask, but he still obediently went to Gongsun Li again.

After a while, Green Hui came to the guest hall, and everyone was still waiting for the corpse to be dissected.

Cai Ye and Han Zhang were slightly surprised when they saw the appearance of Green Hui, but they quickly regained their confident expressions.

Walking to Gongsun Li Zai's side, Gongsun Li Zai was also standing at this time, although his face was a little embarrassed, but he did not have the panic of ordinary people.

"Gongsun Gongzi, if I say that the shrimp is not poisonous, do you believe it?" Lu Hui didn't have too much expression on her face when she said this, it was very ordinary, and she wanted to know what Gongsun Li thought again.

Gongsun Li observed Lu Hui's calm face again, and he didn't know why, he heard a little affirmation that belonged to her. Besides, from the moment he decided to let her out to help him, he felt that he should trust her.

Because he is already in ruin.

"I believe it!" Not categorically, but after a moment of hesitation, he answered.

"Does Gongsun Gongzi dare to try the shrimp himself?" Lu Hui pointed to the lemon shrimp on the table in front of him that had already been served after the incident, and continued to ask.

Gongsun Li looked at Lu Hui again and did not speak. After a few moments, he walked over to the table and was about to pick up his chopsticks.

At this time, Lu Hui grabbed the chopsticks first, quickly grabbed a piece of lobster and put it in his mouth, and said while chewing: "I'm kidding you, how can Gongsun Gongzi be so delicate and risky, if you want to try it, it's also my subordinates to try, it's really delicious!" ”

Gongsun Li looked at her in astonishment. Not only him, but the others also looked at her in astonishment, and Lu Yan looked annoyed that he didn't hold her in time.

"You could have tried it yourself without having to try it yourself, just with livestock!" Gongsun Li said as he watched her reaction a little nervously.

"Why should I borrow something else to prove what I am 100% sure of? Besides, I'm fine, aren't I? Green Hui rightly asked. By the way, I grabbed a few more pieces of lobster to eat, then turned around and told everyone that she had nothing to do.

No matter how unfathomable Gongsun Li looked down at her, where did her confidence come from?

It's getting more and more difficult to figure out this person. But one thing is for sure, he doesn't find her so much of an eyesore anymore.

Looking at Lu Hui, who had nothing to do, everyone's hanging hearts relaxed, including Lu Yan. In fact, everyone still hopes that the wine and food are not poisonous, although they have not started to eat them.

Cai Ye and Han Zhang, who were watching silently, were a little unhappy at this time, but they didn't expect a little girl to run out of the sky and ruin their affairs!

Han Zhang still didn't give up, and said: "Maybe there is no problem with the shrimp, then Gongsun Gongzi, how do you explain the poison in this cook?" That's a living life! ”

Green Hui took a look at this Han Zhang, and he was really positive, could it be that he was the "person with a heart"?

"Of course the shrimp is no problem, silver needle, everyone has experienced, but oranges are different, only the primary school apprentice has tried it, although he has nothing to do, but it does not mean that oranges are not poisonous. It must be known that as long as the poison does not reach the lethal amount, the person who takes the poison can be safe and sound"!

Greenway's words successfully brought the thinking of those present to another breaking point, and to be honest, if it weren't for Greenway's words, maybe many people wouldn't think in this direction. But seeing their bewildered expressions, Green Hui knew that they still didn't understand too much. So Lu Hui could only say to Bai Li: "That is to say, it is very likely that the problem is those oranges that have been 'proven' by the primary school apprentices to be fine, and the people who poisoned them may only have a small amount of poison on the oranges, so Master Ling didn't have anything to do when he first ate oranges, including the junior apprentices, but it adds up, and when Master Ling ingests a lot of oranges, the problem will be strict, and maybe it will really reach a lethal dose!" ”

Everyone understood now and nodded their heads. Lu Hui immediately took advantage of the victory to pursue: "So, my advice is to use a silver needle to measure those oranges, even if you don't use a silver needle, you must use another objective method to prove that the oranges are not poisonous." Witnesses alone don't tell the story! ”

"But the oranges have already been eaten, how can this be tested?" The apprentice replied with a look of annoyance, and suddenly he patted his head again, "By the way, I remembered that I secretly left a small piece in the room, because I didn't want to finish eating, so I went to get it!" ”

"Wait!! Arsenic poisoning does not necessarily require finished arsenic, and some foods can also produce arsenic when ingested! "It's Naruqi again.

Hehe, the 'shield' is finally revealed. Lu Qi must have seen that the shape was not good for him, so he brought out the "food poisoning" as a shield. Green Hui also bypassed the stalk of "food poisoning" just now, because she was afraid that they would not understand, but she didn't expect this person to shake it out by himself. In that case, she should argue with him and see how he is round.

Lu Qi saw that he had successfully attracted everyone's attention, so he continued: "As far as I know, eating shrimp with lemons and oranges will produce arsenic, and when it reaches a certain amount, it will be fatal. Maybe this Master Ling died like this. Things may not be as complicated as everyone thinks! ”

Just now, he looked like he was afraid that the world would not be chaotic, but now he saw that the wind direction was not quite right, so he quickly changed his tone, and he was a little suspicious of "there is no silver here". And that Han Zhang. The two of them sang and sang a good show, which should be inseparable from this bizarre drug case, Lu Hui thought to himself.

Gongsun Li had been quietly watching the conversation between Lu Hui and these people on the side, and also quietly observing everyone's reactions, of course he couldn't find Lu Qi's abnormality. Just now, he was desperately throwing dirty water on himself, and now he is talking suddenly. And since he knew that eating shrimp and oranges together would produce toxic substances, why didn't he say it in the morning. But he hadn't heard of the food poisoning they were talking about. How will this crazy woman pick up?

"This brother, you are a little irresponsible. This is a living life, what is 'maybe', don't take it out if you are not sure, since you said that Master Ling may have died because of eating too many shrimp and oranges, what is the evidence? ”

Hmph, I will be aggressive, this is called treating others the way they do. Green Hui thought to herself.

"This... You take livestock and do an experiment... Only... OK! The more Lu Qi spoke, the more unconfident he became, and in the end he could barely hear the sound. He also seemed to realize that he was about to say the wrong thing, and quickly glanced at Han Chang not far away, who knew that Han Chang was long gone.

"Good!" At this time, Lu Hui clapped his palms, "I am in favor of experimenting with livestock, but I kindly remind this benevolent brother." As far as I know, eating shrimp and oranges together does produce arsenic, but to achieve a lethal dose, the person must eat at least a stone's weight of shrimp, and I don't know how many oranges, and my brother may have to prepare in advance to see if there are any livestock with such a large appetite. After speaking, he gestured with his hand and made a very exaggerated gesture of holding the tree with his hand. Then he added: "But the little woman is also hearsay, not necessarily true, or wait for Brother Ren to do it before you know." Maybe a little mouse can do it. ”

After Lu Qi listened to Lu Hui's words, his face was already blue and white, and he even began to twitch. How could he not know these things that Green Hui said? It's just that he thought too well at the beginning, anyway, no one will know about this food poisoning, and he will pass the matter if he casually prevaricates, as long as it is proved that eating shrimp and oranges together can produce arsenic, no one will care whether it has reached a lethal dose, because it is difficult to say about the amount.

The worst thing is that he thought that the oranges had been destroyed, but he didn't expect that there was still a piece left in the junior apprentice. Otherwise, he wouldn't have taken out the last hole card to talk about things, and he met such an expert as Green Hui. It doesn't matter if you don't do it, it can only show that shrimp and oranges can produce arsenic when eaten together, but it is difficult to achieve a lethal dose, and in the end, you still have to find out those oranges, for fear that Han Shizi will be implicated in the end.

Thinking of this, Lu Qi explained everything, including how to add arsenic to oranges, how to guide Master Ling to poison, and the purpose of doing so was to blame Gongsun Li and so on. It seems to be true.

Green Hui only rolled his eyes in his heart, it was really not fun to stop recruiting himself so quickly. And this heart is too bad, everyone hasn't suspected him yet, and he has confessed to himself. This IQ, this EQ, drunk!

It can only be said that the "caring person" behind this is too careless to find a substitute for the dead ghost. Green Hui looked around, and sure enough, the few pairs of eyes that were faintly felt, just now, were gone. She wanted to pursue it, but thinking about it, she was still a prisoner and couldn't protect herself, and this was a bit too much. Moreover, looking at the current situation, everyone also believed Naluqi's words, thinking that he was undoubtedly the murderer, and she didn't have to say anything.

But it was that Gongsun Li Zai, who had a chilling look in his eyes from beginning to end, just looked at himself without humming, and he was about to be embarrassed. In this matter, it seems that he is the person involved, how does it seem that she is the leader. Also, shouldn't he be grateful to her? Although she didn't care about these inconsequential scenes.

The most irritating thing is that he didn't forget to remind her to go back to the room where she was being held. This person still doesn't understand a little bit of human sophistication!!

After properly handling Master Ling's affairs, the dinner continued. It's just that everyone has no appetite at this time, and it doesn't look like they're celebrating anything at all, and they quickly disperse in a hurry.

In the middle of the night, two people in a room were still whispering, and one of them didn't seem to be very kind.

"Hmph, didn't you say foolproof? In the end, it was not in vain! Cai Ye accused disdainfully.

"I didn't expect a little girl to come out halfway. It's a secret that no one knows, my ancestors used to study food poisoning, and then switched back to 'alchemy' because of the lack of money and conditions, but they still recorded some examples of food restraint that they had found, and oranges and shrimp were one of them. But these were not recorded in the chronicle of the national eunuch, so they could not have known it, and they knew it so clearly that they even knew about the lethal amount. I thought it was leakless, but I didn't expect it to fail! Fortunately, Nalu Qi helped me take the blame! Speaking of which, even Han Zhang himself felt a little cowardly.

"Hmph, it's good to know, it's good that your Nalu Qi confessed his guilt early, if you continue to investigate like this, the fire will burn on us sooner or later! It's just that girl is really born with a bad thing, and she will intervene in everything, if she hadn't promised Gongsun Li to let him take her away after the trial, I would have arrested her and returned to the capital tomorrow! Cai Ye hated and helpless, and his face was angry.

It's a long day!
