Puppies certainly won't get any cerebral hemorrhages. There will be no heart disease, the little Pekingese dog was still alive just now, and now he suddenly fell to the ground and died. Obviously, it has something to do with the few bites of food I just ate.

Fan Wuxian turned out his rosewood needle box. I pulled out a silver needle and tried it. Sure enough, the silver needle turned jet black.

"Damn! It's arsenic trioxide, and they won't change it for potassium cyanide or something? Fan Wuxian said angrily.

The so-called arsenic trioxide is commonly known as arsenic.

Some people have the habit of drinking realgar wine. In fact, realgar is a mineral of arsenic sulfide. This kind of thing is oxidized if it is heated. A white powder is produced. That is, arsenic trioxide. Arsenic.

Ancient production technology was backward. As a result, arsenic is accompanied by a small amount of sulfur and sulfides. When the geosulfur contained in it comes into contact with silver, it can cause a chemical reaction, causing a layer of black silver sulfide to form on the surface of the silver needle.

In modern times, the technology of producing arsenic is much more advanced than in ancient times, and the refining is very pure, and there is no longer sulfur and sulfide. The metal properties of silver are very stable. Under normal conditions, it does not react with arsenic, so the silver needle test often does not work.

Fan Wuxian tested the toxicity with a silver needle, which means that this thing was not obtained through formal channels, and it is very likely that the other party refined it himself. That's why the silver needle turns black. Arsenic is highly toxic and can destroy certain cellular respiratory enzymes when it enters the body. It prevents tissue cells from obtaining oxygen and dies, and can also strongly irritate the gastrointestinal mucosa. Ulcerate and bleed mucous membranes. Blood vessels can also be damaged and bleeding occurs. Destruction of the liver. In severe cases, death can occur due to respiratory and circulatory failure.

In fact. There are also people who do not die after ingesting large amounts of arsenic, which is due to the strong irritation of the stomach caused by arsenic causing intense vomiting. The swallowed arsenic is spit out without being absorbed by the body, so there are no serious consequences.

Arsenic. In fact, it is impure trioxide. It looks like a white ground powder. Once upon a time. The killers chose arsenic as a tool to kill people, in addition to its toxicity, because arsenic is odorless and tasteless, and it is difficult to test on corpses. Therefore, the symptoms of arsenic poisoning are often confused by people with some other diseases.

It was not until the twenties of the XIX century, after the death of the French emperor and famous military strategist Napoleon Bonaparte, that scientists tested arsenic on him. And be aware of the lethal effects of this toxic substance.

When Napoleon first died, it was officially concluded that he had died of stomach cancer. But some scientists think. The wallpaper of Napoleon's bedroom contains a green paint. As the wallpaper gradually decays with moisture. The arsenic component of this coating is gradually oxidized and volatilized in the form of vapor. This was the root cause of Napoleon's death.

Whether or not the secrets of Napoleon's death can be attributed to arsenic. But in France, arsenic is referred to as an inherited powder. It is because, according to legend, many people poisoned their wealthy relatives with arsenic in order to gain the right to inherit the inheritance.

From these legends. It can be seen how toxic arsenic is.

Lots of seafood. Such as shrimp, crabs, clams, oysters, etc. They all contain arsenic, but the amount of arsenic in their bodies is very small, but because the marine environment is becoming more and more polluted. It may lead to higher levels of arsenic in these animals.

High doses of vitamin C and pentavalent arsenic in shrimp undergo a complex chemical reaction. will transform into toxic trivalent arsenic. That is, we often call arsenic. Because arsenic toxicity has a cumulative effect. If you eat like this for a long time. Even if the amount is smaller each time. There is still the possibility of chronic poisoning, (friendly reminder.) If you are eating shrimp and crab and other seafood. Don't eat vitamin C. to avoid food poisoning or toxin deposition. ）

Fan Wuxi pulled the dead little Pekingese dog with his foot. Then said to Tong Xiaoyun. "I'm glad you arrived just in time. If only it had been a little later. It's me lying on the floor! ”

Tong Xiaoyun looked at the motionless little Jingba dog, and she was also afraid for a while. If Fan Wuxian also dies in front of him. That's an unimaginable consequence.

"Do you remember what the girl looked like just now?" Tong Xiaoyun asked Fan Wuxian.

Fan Wuxian thought about it carefully. I found that the girl's heavy makeup was glamorous, and the makeup effect was too heavy. Her hair was also very long, covering two-thirds of her face, and it was very difficult to restore her appearance completely.

But he thought about it again. Since it is at this time to poison yourself. Then the instigator will definitely not be someone else, it must be the group of little devils, except for them. Who else can do such a thing?

So Fan Wuxian said to Tong Xiaoyun, "Later, I must teach those devils a good lesson, and they dare to poison me." Isn't this self-defeating?! ”

"Don't be impulsive, it's better to call the police for this matter." Tong Xiaoyun was afraid that Fan Wuxian would do something more extreme, so he pulled his arm to dissuade him.

How high Fan Wuji's real skills are, although Tong Xiaoyun doesn't know very well. But she knew that these devils in the ring were not enough to see Fan Wuxi. If Fan Wuxian is really angry. Maybe a punch can really kill a ground, if something like this happens. That's a problem.

This is an exchange competition, and the main purpose is to communicate. The main theme is Sino-Japanese friendship. If there is a fatality, it will cause international disputes.

Therefore, Tong Xiaoyun felt a little worried, so she didn't want Fan Wuxian to go to the game again.

"If you don't go to the game, you can't do it. Personal matters are small, but the national body is big! How could Fan Wuxian let go of those little devils, so he said sternly to Tong Xiaoyun, "I think back then, the hero Huo Yuanjia knew that he was poisoned, but he still insisted on going on stage to compete with the Japanese. What kind of spirit is this? I'm a junior. How can the spirit of Jingwu fall. That's a no-go! Not only do I have to play against them, but I have to make them lose badly. Let them regret coming to China to spread wild! ”

In fact, Huo Yuanjia did not compete in martial arts after being poisoned, it was the plot after processing.

The real experience that year was when the president of the Japan Judo Association led a delegation to China, and Huo Yuanjia defeated more than ten masters in a row. The Japanese were shocked, so they set up a wine banquet to invite Huo Yuanjia, during which they saw Huo Yuanjia coughing. invited a Japanese doctor to treat him, and Huo Daxia was upright. There is no doubt about him. As a result, he died of poison a few days later.

Although Huo Daxia died under the poison of the Japanese after all, he did not die after the poison failed in the ring, so to speak. Huo Daxia rarely failed in his life.

However, according to the later recollections of Chen Gongzhe, one of the actual operators of the early Jingwu Society, Huo Yuanjia originally suffered from hemoptysis. Seizures are frequent. The Japanese sold medicine to Huo Yuanjia, saying that it could cure hemoptysis and cure lung disease. Huo Yuanjia believed it. After buying it and taking it, the condition became more serious.

Chen Gongzhe did not judge right and wrong when he said this, and he did not say that the Japanese poisoned. However, he also affirmed the fact that Huo Yuanjia had taken Japanese medicine and his condition had worsened. In addition, he directly pointed out the reason for Huo Yuanjia's illness, which was when Huo Yuanjia was a teenager. He once practiced qigong and swallowed qi, which injured his lungs, resulting in hemoptysis and a sallow complexion. Therefore, it is known as the yellow-faced tiger.

He was more inclined to think that Huo Yuanjia died of illness caused by his inability to practice qigong.

Tong Xiaoyun naturally didn't know the cause of Huo Daxia's death, but only learned it when she watched TV. It has something to do with the poisoning of the Japanese, and this time Fan Wuxian was actually poisoned. It directly led to her being very disgusted with the Japanese.

However, seeing that Fan Wuxian looked like tens of millions of people, Tong Xiaoyun also knew that she couldn't persuade him. After all, men have manly principles, and it is impossible to retreat because of their own dissuasion and the intimidation of the enemy's conspiracy. From this point of view. Tong Xiaoyun felt that Fan Wuxian was a hero, and he was worthy of treating him with his heart.

However, Fan Wuxian felt that he should call the police, so as to save others from not knowing that he was almost poisoned. So I called the local police station and told me what happened.

The other party heard that it was a poisoning case, and he also poisoned a dog. Immediately expressed great concern. He instructed Fan Wuxian and them to protect the scene. Wait for their people to come to the door for verification.

However, Fan Wuxian looked at the time. It's about to be the time specified for the game, and there is no way for him to wait, so he lets Tong Xiaoyun stay here. I called my men again. Called two people to come and help. He himself rushed to the gymnasium. Take part in this morning's final.

Tong Xiaoyun was waiting in Fan Wu's dormitory. About half an hour passed. Just waited for the police to come. However, at the same time as the police, there was also Tang Zhi, the head of the Shanghai Department of Security.

"Why isn't Mr. Fan here?" Tang Zhi asked with some curiosity.

Tang Zhi knew Tong Xiaoyundi. Because Fan Wuxian is now in charge of the safety of the land, they are directly responsible for taking over the land. So when the police received a report from Fan Wuxi. immediately informed Tang Zhi of the news, as soon as he heard that Fan Wuxian was almost poisoned, he naturally didn't dare to take it lightly, and rushed over in a hurry.

"I'm not sick and I'm going to participate in this morning's exchange competition, so I'm going to wait here." Tong Xiaoyun explained what had just happened to Tang Zhi in detail. Then he said to him, "I recalled it later. I drew a portrait of the girl, but because she deliberately strengthened the makeup. He also covered most of the ground holes with his hair. So it's hard to identify. ”

Tang Zhi took the portrait handed to him by Tong Xiaoyun, looked at it, and really felt that it was very difficult to recognize, although Fan Wuxian painted it vividly, but he had to follow the map. Still can't do it.

"Who do you think is most likely to have poisoned?" Tang Zhi asked.

"I guess it's the Japanese." Tong Xiaoyun replied.

There are no pop-ups
