Qin Hongfei entered under the name of Tan Zuo. At 4 pm, she waited for Yu Chu to come and entered the exchange conference in the name of Professor Tan's student. Qin Hongfei also got a quota for Jiang Wan and Zhuang Yan, and followed another professor to enter.

Tan Zuo told Qin Hongfei, "After entering, as long as you have a badge, you can basically move freely. Miss Qin, you can see if there is anything you like. There will be an auction at the end. If you like it, you can take a picture."

Qin Hongfei took note.

The original intention of this exchange conference was to give these young people an opportunity to visit, and Jiang Wan and Zhuang Yan accompanied Qin Hongfei and Yu Chu.

Professor Tan reminded the two boys again, "Take good care of Miss Qin and Yu Chu, don't just play around."

In fact, Zhuang Yan and Jiang Wan would do the same without being told.

They were not qualified to come in, and they were able to come in because Qin Hongfei asked Tang Qiduo for two more places.

The spacious venue had display stands on all sides except for the platform in the center, and there were related introductions to things on the side. There were so many things that it was difficult to find the target for a while.

Qin Hongfei took Yu Chu and said, "Let's go..." Just as she was about to find an artificial heart, she suddenly saw Qin Yan and Tang Xiaojin from a distance.

Tang Xiaojin made a gesture, Qin Hongfei looked around, and took Yu Chu over.

As soon as they approached, Tang Jinnan said directly, "The artificial heart is in display cabinet No. 210."

They came here today, basically for the artificial heart.

So after arriving, they started looking for it.

Qin Hong was too nervous, "Let's go..."

In display cabinet No. 210, it is called artificial, but in fact, to put it bluntly, it is a mechanical heart. It is made to imitate human blood vessels, nerves, and veins, but it is operated by electronics. There is a related introduction next to it. It is a product from a research institute in the United States. It has a service life of ten years and has 18 clinical experiences. It can replace the flesh and blood heart and will not have rejection problems, allowing people to live a normal life.

Yu Chu was delighted, but when she turned around and saw the expressions of Tang Jinnan and Qin Hongpin, she suddenly became cold, "This heart..."

Tang Jinnan said, "The introduction only talked about the advantages of artificial hearts, but did not mention the disadvantages. I saw that the heart came from a research institute in Country M."

Yu Chu did not understand and asked, "Brother Tang, what happened to the research institute in Country M?"

Tang Jinnan said that Country M was fine, but the research in Country M was notoriously pathological in the industry. "In their eyes, clinical experience is better than facts." They will spend a lot of money to hire people to do trials for clinical experience and constantly improve the technology..."

Zhuang Yan said, "That's just right."

Qin Hongfei closed the introduction and said, "On the contrary, this shows that the attitude over there is that research success and clinical experience are far more important than human lives. To put it bluntly, the relationship between China and Country M is not good. If the other party really has an absolute advantage in this kind of technology, it will not be introduced to China. The purpose of introducing it to China is very simple..." "

They are looking for mice." Tang Jinnan simply concluded.

"Yes." Qin Hongfei was a little afraid of offending Yu Chu, but she still had to make it clear: "They need test samples to improve clinical experience in this area. The human heart is irreplaceable. You said that after replacing the mechanical biological heart, it is no different from a normal person. The mechanical heart alone requires more control over human emotions. For people with bad tempers, they need to be more cautious and cannot do too intense exercise, otherwise it will cause mechanical operation load, which will cause the heart to stop functioning..."

To be honest, basically, if the human organs are replaced, there is no such thing as a normal person.

Everyone has to rely on being cautious to survive.

Qin Hongfei looked at Yu Chu worriedly. Over the past year or so, Yu Chu would always look up information and run around for anything related to this aspect, but without exception, he was disappointed. Fortunately, Yu Chu was much stronger than they thought. He said, "It doesn't matter. It's better to have hope than to have no hope. Even if we take a step back, this is a way out if we really have to."

Qin Yan said, "Medical science is developing rapidly nowadays. Don't be discouraged. There will always be a way." Yu

Chu also nodded optimistically, even though they all knew that this was just self-consolation, but at least there was still hope.

Qi Wu wanted to go and look at the herbs, Tang Jinnan asked, "I want to

go and look at the herbs, do you want to come with me?" Qin Hongfei was not interested in herbs, but was more interested in medical machinery, "You go, I'll go look at something else, Zhuang Yan and Brother Wan, you guys go on your own, you don't have to follow me."

Zhuang Yan thought it was not good, "Professor Tan..."

Qin Hongfei said, "It's very safe here, even if something really happens, Meng Yu can't solve it, and you guys are useless."

Well, let's be honest.

Jiang Wan couldn't hold back any longer, Qin Hongfei said so, so he went immediately.

Qin Yan didn't leave. Seeing Qin Hongfei looking at him, he paused and said, "I don't want to see anything. I'll follow you."

Qin Hongfei looked at him and said, "Are you worried that Dong Qier will suddenly appear?"

Qin Yan neither denied nor admitted.

He did have this worry.

Qin Hongfei thought it was unnecessary. Even if Dong Qier really appeared, the first person to deal with would definitely be Qin Yan, not herself.

Speaking of which...

Bai Qishi attaches so much importance to training people. If he uses Qin Yan as bait, I don't know if he can catch Dong Qier. If Qin Yan is not enough bait... She was thinking wildly.

Qin Yan suddenly looked at her as if he had sensed something, "What are you thinking about?"

Qin Hongfei said, "No."

Qin Yan said firmly, "Are you thinking of using me as bait?"

Qin Hongfei: "…………"

She said seriously that it was not the case, "Don't think about it, I'm not that kind of person."

"Really not."

"When you are lying, you like to stare at people."

"……"

The brother and sister looked at each other.

The bodyguards next to them saw it and always felt that a fight might break out at any time. They were thinking what would happen if a fight broke out. Should they stop the fight?

At this time, there were two people in the other corner of the exchange meeting.

One of them was trying his best to persuade, "Miss, let's go back first. I have asked the boss to help find the whereabouts of the young master. There will be news soon. Don't make trouble at this time."

Jiang Yier looked up with a pale face and asked, "How fast is fast?"

The bodyguard fell silent, he didn't know.

Jiang Yier said, "When my godfather disappeared, you also said it was fast. Now my brother is missing, you also say it is fast. I don't trust you."
