Then, Yila saw the lunch box that Jiang Feng had just opened and asked curiously: "Have you cooked?"

Jiang Feng immediately replied: "No, someone just sent it here, saying that it was the breakfast given to the contestants by the school. I opened the lid and took a look, and you came in."

"It looks pretty good, it's so hearty!" Yila looked at the food in the lunch box and said with some depression.

Jiang Feng looked at Yila's expression, smiled, and put the lunch box just now on the ground, and then said, "I still like to eat what you sent me. Well, I like to eat your tofu..."

"Hate! Come and drink it while it's hot!" Yila was quite happy to see Jiang Feng like this.

The little Jingbago smelled the fragrance of the lunch box on the ground, so she came up, pulled the lunch box over with her paw, and then licked the meals with her tongue, and specially picked the shredded meat inside to eat, looking like she was enjoying it.

"This unlucky puppy will have to find someone to clean up later." Jiang Feng drank the tofu brain, glanced at the dog, and said with some depression.

While he was talking, the little Jingba suddenly twitched, and then whimpered, stretching out his four legs, foaming at the mouth and falling there no longer moving.

"I'm x?" Jiang Feng and Yila were stunned when they saw this. It took a long time to react. Could it be that the food is poisonous?

Who wants to harm me? Jiang Feng suddenly burst into cold sweat.

The puppy will definitely not have any cerebral hemorrhage or heart disease. The little Jingba dog was still jumping around just now, but now he suddenly fell to the ground and died suddenly. It is obviously related to the few bites of food he just ate.

Jiang Feng took out his red sandalwood needle box, pulled out a silver needle, and tried it, and it turned out that silver needle turned black.

"Damn! It's actually arsenic trioxide. Can't they change some potassium cyanide or something?" Jiang Feng said furiously.

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. If this thing is heated and oxidized, it will produce white powder, namely arsenic trioxide and arsenic.

The backward production technology in ancient times caused arsenic to be accompanied by a small amount of sulfur and sulfide. The sulfur contained in it came into contact with silver, and chemical reactions could be carried out to create a layer of black silver sulfide on the surface of the silver needle.

In modern times, the technology of producing arsenic was much more advanced than in ancient times. The refining was very pure and there was no longer sulfur and sulfide. The metal chemical properties of silver were very stable and would not react with arsenic under normal conditions, so silver needles often did not work.

Jiang Feng used silver needles to test the toxicity, which means that this thing was not obtained through formal channels. It is very likely that the other party himself extracted it, which makes the silver needle black.

Arsenic is very toxic. After entering the human body, it can destroy respiratory enzymes in certain cells, prevent tissue cells from obtaining oxygen and die. It can also strongly stimulate the gastrointestinal mucosa, causing mucosa to ulcerate and bleeding. It can also destroy blood vessels, cause bleeding, and damage the liver. In severe cases, it will die from respiratory and circulatory failure.

In fact, some people do not die by taking a lot of arsenic. This is because the strong stimulation of arsenic to the stomach causes strong vomiting. The swallowed arsenic is vomited out without absorbing it through the body, so there is no serious consequence.

Arsenic is actually impure arsenic trioxide, which looks like a white powder. In the past, killers chose arsenic as a tool for killing people. In addition to its toxicity, it is also difficult to detect on corpses because arsenic is odorless and odorless. Therefore, the symptoms of arsenic poisoning are often confused by people with other diseases.

It was not until the 1820s that after the death of the French emperor, the famous military strategist Napoleon Bonaparte, scientists found arsenic from him and realized the lethal effect of this toxic substance.

When Napoleon died, the official conclusion was that he died of gastric cancer. However, some scientists believed that Napoleon's bedroom wallpaper contained a green coating agent. As the wallpaper gradually became damp and rotted, the arsenic component doped in this coating agent would gradually oxidize and evaporate in the form of steam, which is the fundamental reason for Napoleon's death.

Regardless of whether the secret of Napoleon's death can be attributed to arsenic, in France, people call arsenic inheritance powder because it is said that many people use arsenic to poison wealthy relatives to obtain the right to inherit the inheritance.

From these legends, we can see how powerful the poisonous effect of arsenic is.

Many seafood, such as shrimp, crab, clams, oysters, etc., contain arsenic in their bodies, but the arsenic content in their bodies is very small. However, because the marine environment pollution is getting worse and worse, the arsenic content in these animals may reach a higher level.

High doses of vitamin C and pentavalent arsenic in shrimp bodies will be transformed into toxic trivalent arsenic after complex chemical reactions, which is what we often call arsenic. Because arsenic toxicity has a accumulation effect, if you eat like this for a long time, even if the amount is small each time, there is still a possibility of chronic poisoning. (Friendly reminder, if you eat seafood such as shrimps and crabs, don’t eat vitamin C to avoid food poisoning or toxin deposition.)

Jiang Feng pulled the dead little Jingba dog with his feet, and then said to Yila: "Luckily you came in time. If you were one step later, I would be the one lying on the floor!"

Yila looked at the motionless little Jingbagou, and felt a little scared. If Jiang Feng died in front of him, it would be a unimaginable consequence.

"Do you remember what the girl looked like on the food delivery ground just now?" Yila asked Jiang Feng.

Jiang Feng thought about it carefully and found that the girl was wearing heavy makeup, and the makeup effect was too heavy, and her hair was dragged very long, covering two-thirds of her face. It was very difficult to restore her appearance intact.

But he thought about it again. Since he poisoned himself at this time, the instructor would definitely not be someone else, but the group of Japanese devils.

Who else can do such a thing besides them?

So Jiang Feng said to Yila: "I must teach those Japanese a lesson later. They dare to poison me. Isn't this a way out?!"

"Don't be impulsive. It's better to call the police." Ira was afraid that Jiang Feng would do something more extreme, so he pulled his arm to dissuade him.

Although Yila didn't know much about how good Jiang Feng's real skill was, she knew that just these Japanese devils on the ring were not enough for Jiang Feng to see. If Jiang Feng was really angry, maybe one punch could really kill one.

If such a thing happens, it will be troublesome.

This is an exchange competition, the main purpose is to exchange. The main purpose is China-Japan friendship. If a person dies, it will cause international disputes.

Therefore, Yila felt a little worried and didn't want Jiang Feng to continue the competition.

"It's not OK to not go to the competition. Now I'm the only Chinese student left. If I don't go, then no Chinese students will participate in the competition. The personal affairs are small, and the national physical fitness is big!" Jiang Feng could have let the Japanese go, and then said righteously to Iraq, "I remember that the hero Huo Yuanjia knew he was poisoned, but he still insisted on going to the stage to compete with the Japanese. What kind of spirit is this? As a junior, how could I let the spirit of Jingwu fall? That's absolutely not OK! Not only do I have to compete with them, but I also want to make them lose miserably, making them regret coming to China to act wildly!"

In fact, Huo Yuanjia did not compete after being poisoned by others, but it was the plot after the novel was processed.

The real experience that year was when the president of the Japanese Judo Association led a delegation to China. Huo Yuanjia lost more than ten masters in a row. The Japanese were shocked and set up a banquet to invite Huo Yuanjia. During this period, he saw Huo Yuanjia coughing, so he invited Japanese doctors to treat him. Huo Daxia was upright all his life and did not doubt that he was there. As a result, he died of poison after a few days.

Although Huo Daxia died after all, he died because of the Japanese poison, but he did not die after the poison failed on the ring. It can be said that Huo Daxia rarely lost in his life.

However, according to Chen Gongzhe, one of the actual organizers of the Jingwu Association, later recollections, Huo Yuanjia was originally suffering from hemoptysis and often had attacks. The Japanese sold medicine to Huo Yuanjia, saying that it could cure hemoptysis and cure lung disease. Huo Yuanjia believed it, but after buying it, the condition became worse.

Chen Gongzhe said this without a judgment on right and wrong. He did not say that the Japanese were poisoned, but he also affirmed the fact that Huo Yuanjia's condition worsened by purchasing Japanese medicine. In addition, he directly pointed out that the reason why Huo Yuanjia was sick was that when Huo Yuanjia was young, he practiced Qigong and swallowed Qi, which caused him to suffer from hemoptysis and his face was sallow, so he was known as a yellow-faced tiger.

He was more inclined to think that Huo Yuanjia died of a disease caused by his failure to practice Qigong.

As a Korean, Yila naturally didn't know the cause of Huo's death. She just learned that it was related to the Japanese's poisoning while watching TV. This time, Jiang Feng was also poisoned, which directly led to her being very disgusted with the Japanese.

In addition, seeing Jiang Feng's enthusiasm for going away even though he was tens of millions of people, Yila knew that she could not persuade him. After all, men had the principle of men, and it was impossible for them to retreat because of his dissuasion and the conspiracy of the enemy. From this point of view, Yila felt that Jiang Feng was indeed a hero and worthy of his care to treat him.

However, Jiang Feng felt that he should call the police so that others would not know that he was almost poisoned by others, so he called the Beijing Public Security Bureau and told the matter.

When the other party heard that it was a poisoning case and poisoned a dog, he immediately expressed his concern and ordered Jiang Feng and others to protect the scene and wait for their people to come to check.

However, Jiang Feng looked at the time and it was time for the game. He had no choice but to wait, so he asked Yila to stay here, called his subordinates and called two people to help. He rushed to the gymnasium to participate in this morning's competition. (To be continued. Please search for Piaotianwen, the novel is better, updated and faster!)
