...... Chapter 372 Oxygen Poisoning This is just the time before preparing to sign the contract, and it was really time for me to come, at this time, the singer on the stage had finished singing, and the staff immediately moved the table up, and the documents and products of his pomelo were all placed, and under the escort of his subordinates, Mi Ran and Nong Yaode got rid of the reporter and walked on stage.

At this time, there happened to be a waiter smiling and walking over with a tray, Chen Han took a glass of red wine casually, tasted it, it was very good, although the year was not enough, but it was a world-famous brand of good wine, it is estimated that each bottle will be worth more than three thousand, with such a large wine party to be able to use this wine is already very good.

"Now we have invited Miss Mi Ran, President of Mi Group, Mi Culture and Entertainment Media Company, and world-famous Tianxian superstar, and Mr. Nong Yaode, Deputy Secretary of Changhai Municipal Party Committee, Mayor of Changhai City."

As soon as the two of them walked on the stage, thunderous applause suddenly rang out below. All the cameras and cameras and countless eyes were on them. The signing ceremony was broadcast live by Changhai City TV and provincial TV. Although the people outside couldn't come in to see the star, Mi Ran and Nong Yaode were also very thoughtful, so that people could see a big screen outside, so after a few seconds of slowing down, they also burst into warm applause.

This kind of warm applause made Nong Yaode, who walked on stage with a calm smile on his face, sigh secretly in his heart. Only fanatical fans can be so enthusiastic, and now although he is a mayor with a population of 10 million, he has not applauded so warmly when he goes to a factory with tens of thousands of people to inspect a small speech, and there are more people who are cold bystanders.

Everything was going on in an orderly manner, and soon Mi Ran and Nong Yaode signed it, and the two sides shook hands and took pictures. It all went very well.

, Wai"

Oh no, someone fell"

Something went wrong, someone fell"

Suddenly there was a chaos, at the back of the press seat, there was a place for the fan group, and the people who could come here at this time were the kind of people like the presidents of the Miran fan associations in various places, so there would be no problems, even if the fans who came today. It's also carefully selected to avoid anything else.

However, at a critical moment, the problem was also solved. After someone screamed, the reporters turned their cameras and looked this way.

At this time, several guards and bodyguards had already leaned in the direction of Mi Ran and Nong Yaode to avoid anything This is a live broadcast, plus there are many media. Something happened suddenly, Nong Yaode couldn't help frowning, and immediately called his subordinates over: "Go and see, what's going on." ”

The front was very chaotic, and it was useless for him to squeeze in. And he standing there steadily, it can play a role in stabilizing people's hearts.

Chen Han originally just wanted to join in the fun. After a while, he approached Mi Ran and his old brother Nong Yaode to say hello to them and left, but he didn't expect a sudden change.

As soon as Chen Han's body moved, the people in front of him involuntarily leaned to the sides as if they had encountered water to avoid water droplets, and Chen Han had already stepped in. Those people felt a force on their bodies to move to the sides, and then returned to normal, and the next moment Chen Han had already entered inside.

At this time, I saw a middle-aged man coughing at the moment, "already showing some difficulty breathing, clutching his chest in pain, obviously his chest is very painful." It was extremely painful.

Taking advantage of the busy surroundings, Chen Han took a quick look again, at this moment, those reporters and cameramen rushed into it, Chen Han had already retreated in a flash, just like when he came in, the place where he walked was like encountering the sea water to avoid the droplets, and then automatically replied, but the process was too fast, these people just felt that their bodies shook to the side of the body, and they had already returned to normal.

After Chen Han walked out of the crowd, he glanced at Mi Ran on the stage, and said in a controlled voice: "This person is just oxygen poisoning, it is estimated that your fans are too excited, because of physical reasons, you come down and use a bag to cover his mouth, and it will get better soon."

The performance of oxygen poisoning varies greatly from person to person, general oxygen poisoning, as long as the partial pressure of oxygen is too high, without any other auxiliary measures, Mi Ran, who was standing on the stage, suddenly heard Chen Han's words, and couldn't help but be stunned "looked around quickly, Chen Han actually came, where is the person." How his words sounded like they were in his own ear.

Oh. That's right. This is the method of sound transmission, Mi Ran suddenly remembered that this person who had listened to the Long family talk about it, but suddenly heard Chen Han's voice and knew that Chen Han was actually here. Mi Ran was still extremely surprised.

In fact, just now she had a little complaint in her heart because this matter was facilitated by Chen Han, but he turned out to be good, and he didn't care about it after he finished speaking, and he didn't come this time, and now he suddenly knew that Chen Han was here, and he was happy.

Chen Han said lightly: "Don't look at it, there are so many people." Your eyesight can't find me, you hurry down and save people, just take this opportunity to boost your popularity"

Oxygen poisoning, oxygen can still be poisoned, Mi Ran was very puzzled, but since Chen Han said so. She also immediately stepped forward and asked the waiter to fetch a bag, and quickly solved all this according to the method Chen Han said.

This time it was even more lively, this sudden episode made those media very excited, and the fans on the periphery were even more excited, although Mi Ran didn't know how people could suddenly be poisoned by oxygen, but since Chen Han said so, it must be right, Mi Ran also said a few words to the fans cordially, and then when the media asked, Mi Ran's words naturally sounded better, and he had to learn some basic knowledge super fast while strengthening his body in the martial arts hall. Then he lost no time in carrying the Niu Family Martial Arts Hall out.

When she said this, Mi Ran looked around, but unfortunately, she still didn't see Chen Han, but she believed that Chen Han should be able to hear it.

Of course, Chen Han, who was in the crowd, also heard some people whispering, and also wondered if this was a show, but it was quickly denied. After all, it's not like your average press conference. It was a signing meeting led by Nong Yaode, the mayor of the vice provincial level, and people who were a little more normal at this time would not be like this.

The head is always on someone else's neck. Anytime there is always a different opinion on a matter, even if it is the truth that the vast majority of people think is true, some people will say that the truth is always in the hands of a few. This is a minutiae.

The next thing was more boring, Chen Han didn't stay here, and then went to the surrounding Disneyland under construction and several other attractions to take a look, Changhai City around the force of Sini Park to build a new tourist attraction in Changhai. Now it has begun to bear fruit, at night, K workers also have a night market with unique coastal characteristics, and the characteristics of many ethnic groups around are also repented, some of which are for Chen Han, whether it is the Disneyland that has not yet been built or the venue, Chen Han is very comfortable in and out.

There was a temporary lounge at the back of the signing meeting, and Nong Yaode and Mi Ran, who had been busy for more than an hour, walked in, Nong Yaode was extremely well maintained, and Mi Ran was now in good health, and both of them were in good spirits.

When the two came in, the secretary had already poured a cup of tea for Yaode, and Mi Zi's agent also poured her a cup of freshly brewed coffee, and Nong Yaode looked at Mi Ran with a smile: "I really didn't expect that Mr. Mi also knows first-aid knowledge, and I have heard about this health knowledge before when I was poisoned by oxygen poisoning." But I've never seen it, if you hadn't just mentioned it, I wouldn't have known that this person was actually poisoned by oxygen, if it wasn't for timely treatment, it wouldn't look good once the venue was messed up, after all, this was a live broadcast from Changhai City and the whole province, and there were hundreds of people from the media at the scene."

Bring this up. Mi Ran hurriedly waved his hand and said, "Mayor Nong, don't praise me, how can I understand this, it was all told to me by Chen Han just now." ”

Chen Han. Ji Yaode was slightly stunned: , is he here?

Little hmm. Mi Ran nodded and said, "At that time, he transmitted the message to me, and I knew what to do, in fact, I also wanted to go back and ask Chen Han, how can a good person still be poisoned by oxygen." ”

As early as the middle of the oral century, the British scientist Paulbert first discovered that if animals were allowed to breathe pure oxygen, they would be poisoned, and so would humans. If the person is greater than. In the pure oxygen environment of field A (half an atmosphere), it is toxic to all cells, and if you inhale it for too long, you may have 'oxygen poisoning'

The destruction of the capillary barrier of the lungs "leads to pulmonary edema, pulmonary congestion and hemorrhage, and the weight of the body affects respiratory function, which in turn causes damage to various organs due to hypoxia." In a pure oxygen environment with a planing ratio (atmospheric pressure), a person can only survive Sun Bu Shi. Pneumonia will occur, which will eventually lead to respiratory failure, scorpion suffocation and death. In the Q ratio (2 atmospheres) high-pressure pure oxygen environment, people can stay at most ultra-fast to an hour, and more than 3 cases of brain poisoning, and the rhythm of life is disordered. Spiritual Buddha chaos. Memory loss. If enough oxygen is added (3 atmospheres) or even higher, brain cells will degenerate and die within a few minutes, and convulsions will lead to death.

In addition, excessive oxygen intake can also promote aging. Oxygen entering the body reacts with oxidases in cells" to produce hydrogen peroxide. This in turn becomes lipofuscin. This lipofuscin is a harmful substance that accelerates cellular aging, and it accumulates in the heart muscle. Aging of myocardial cells and decline of cardiac function; Accumulation on the walls of blood vessels, causing aging and hardening of blood vessels; accumulates in the liver, weakening liver function; Piled up in the brain, arching up intelligence declines. memory declines, the person becomes demented; It builds up on the skin, forming age spots.

Except for a few anaerobic microorganisms in the biological world. Organisms cannot survive without oxygen, which is the most important gas in the body's respiration and metabolism. However, oxygen is not "beneficial and harmless": upper respiratory tract irritation occurs even when breathing above pure oxygen hiss at atmospheric pressure; Respiratory hyperbaric oxygen (Kam Bi Zhi Zhi, help) can appear after a certain period of time, obvious symptoms and signs of oxygen toxicity can appear. ”

Just as Mi Ran finished speaking, Chen Han's voice suddenly sounded in the room, and he spoke slowly without hurry, as soon as he heard Chen Han's voice, Nong Yaode and Mi Ran both stood up, and Nong Yaode's secretary looked around strangely, surprised where the voice came from.

As for Mi Ran's agent, he is so good, and he often goes in and out with Mi Ran in the Niu Family Martial Arts Hall, and he has long been familiar with these situations.

"Who? Stop... Just as Chen Han's words were finished, the voice of the guard sounded outside the door.

"Chen Han, you're getting more and more powerful now, come in." Nong Yaode said happily, and the two guards outside the door heard Nong Yaode's voice, and hurriedly stepped aside to stretch out their hands to open the door for Chen Han.

Chen Han walked in with a smile and shook hands with Nong Yaode first, "Brother, I have successfully completed the task." ”

Chemiran was angry and funny in his heart. Nong Yaode also told Mi Ran that he asked Chen Han to help in the middle, but how could he help like this. I mentioned to myself a phone number, and now I say that I have completed the task, and I blame myself, why don't you delay it.

When he saw that Chen Han was already looking at him at the moment, Mi Ran deliberately said, "I thought Baidu would suddenly be able to speak."

Hear Miran's words. Chen Han said: "Mi Ran, you are a bit of a dog biting Lu Dongbin, I don't know the hearts of good people, I will be kind and patient to start with the basics, you actually said so, it seems that a good person really can't be a good person!"

Nong Yaode was also stunned when he heard the conversation between the two, not to mention Mi Ran's slightly wrong expression. Let's just say Chen Han's words, Mi Ran is not only an international-level emperor superstar, but also an absolute strong woman. It can be said that she is a rare stunning woman. Even he secretly exclaimed, thinking about the fans who were too nervous and poisoned just now, and then thinking about the fans who were so hot, Mi Ran's suction power is self-evident.

Even if Nong Yaode sees Mi Ran, although he will not be like her fans, his attitude towards her is different from that of ordinary people, this is the charm, this is a human nature, but Chen Han doesn't seem to be cold to Mi Ran at all.

Nong Yaode's heart moved, could it be that the two of them, Mi Zai was also said like this for the first time, she was also stunned after Chen Han finished speaking, and when she wanted to say something more, Chen Han had already turned his head and said to Nong Yaode: "Old brother, grandpa is now in the Niu Family Martial Arts Hall." Grandpa mentioned you at dinner today. He also said that he hadn't seen Jianhua for several years. Grandpa said let you go over for a meal if you are free."

Nong Yaode was originally thinking in his heart, feeling that there seemed to be such a subtle abnormality between Chen Han and Mi Ran, and suddenly heard Chen Han mention Chen Lao, Nong Yaode's expression was correct: "Grandpa is here, when did he come, why didn't he inform me earlier?"

Nong Yaode couldn't help but be overjoyed, this is a joy from the heart, his life changed after meeting Chen Lao, Chen Lao never really came forward to do anything, but he knew that without Chen Lao, he would not have what he is today, although it is not a blood relationship, but this kinship is real.
