Qin Guan only knew that his parents were in Heizhou, but he did not expect that they were in the southernmost part of Heizhou, Rainbow Country.

Didn't they support the production and construction of Heizhou?

Although Qin Guan's mental point scanning system has become more and more powerful, it is impossible to scan all the spiritual points in the world and scan a certain person.

My parents went to Rainbow Country, what did they do in Rainbow Country? Could it be that the country has given them special tasks?

"Your parents are all doctors." Major Yang said: "As medical staff, but I went to Heizhou, naturally to improve the medical standards there. They did it very successfully. Under their hands, many black people are They regained their lives. Two years ago, they went to the Rainbow Nation, went to the Rainbow Nation, and learned the most advanced medical technology there."

Hearing what Major Yang said, Qin Guan couldn't help asking, "Is it a heart transplant operation?"

"Sure enough, you know everything." Major Yang was also taken aback when he heard Qin Guan's question. He didn't expect Qin Guan to guess it?

What advanced medical technology needs to be studied in Rainbow Country? It must be a heart transplant!

The current Rainbow Nation is still in the period of white rule. They are quite smart, and many technologies are also at the advanced level in the world, such as this heart transplant.

The world's first heart transplant operation was successful in a hospital in Rainbow Country on December 4, 1967. The operation was performed by Dr. Chris Barnard, a rainbow foreign doctor.

He has transplanted the heart of a 25-year-old woman who died in a car accident to a 53-year-old Polish male immigrant. The success of this operation created a precedent for human heart transplantation.

However, because the rejection problem was not properly resolved, the patient who underwent his operation died two weeks later. Even so, Barnard is famous for that operation. In the following decades, he has performed more than 70 heart transplant operations, accumulating valuable experience for similar operations in many countries around the world.

It can be said that the most advanced technology for heart transplantation is in Rainbow Country.

Heart transplantation is too knowledgeable.

At present, there are still many problems that cannot be resolved, such as the source of donors and related legal and ethical issues, rejection of organs after transplantation, and selection criteria for donors and recipients.

Moreover, the mortality rate after heart transplantation remains high. 60% of patients die on the 8th day after surgery. The average survival time of heart transplant patients is only 29 days.

However, this has not hindered the pace of medical experts around the world. They are working hard to overcome the difficulty of heart transplantation. In the 1970s, more than 20 heart transplant operations were performed every year around the world.

In this era, the most important thing is to solve the core problem-anti-rejection.

This was until after the emergence of cyclosporine, which saved organ transplants from water and fire. By the 1980s, cyclosporin A had begun to be used in clinics. The survival rate of patients after heart transplantation was greatly improved, and heart transplantation operations quickly became popular.

In the history of that parallel world, in 1987, the Eagle Nation government announced that heart transplantation had become a routine operation in major medical centers.

It is naturally a good thing for my parents to learn such a medical operation.

Heart transplantation is actually being tested in China. In 1978, Huating Ruijin Hospital completed the first heart transplant operation in Han. Because cyclosporine is not yet on the market, and there is a lack of effective immunosuppressive drugs, it is difficult to solve the rejection reaction after heart transplantation. Similar to the survival of heart transplant patients worldwide during the same period, the patient only survived 109 days.

After that, it has been at a low point.

Now, after hearing Major Yang say this, Qin Guan was naturally very happy, and understood why there was no news of them in recent years. The current Rainbow Nation is still under sanctions. Although it is a medical cooperation, any relationship with such a country will cause a lot of trouble. Therefore, everything is better to be careful, at least for now. Guan thinks so.

Now, many things are tied to Rainbow Nation.

"Then when will they come back?" Qin Guan asked.

They never dreamed that before they set off, their son, who was just an ordinary worker, has now become the country's most powerful arms dealer, right?

Qin Guan was very proud of this.

"It's not clear yet, let's talk about it later." Major Yang said: "Now, I will let you know in advance."

"Brother Yang, looking at you like this, it seems that something is hiding from me." Qin Guan said.

Major Yang shook his head, which was the end of the conversation.

After sending away Major Yang, Qin Guan lifted his legs and thought about the recent events. After sorting it out, more and more, the arms sales situation is very good. I don’t know how the frigates are designed. I always want them. I have exchanged one, but I haven't had a chance to do it. I haven't asked about any transport aircraft, passenger aircraft, early warning aircraft, etc. for a long time. I seem to be the busiest person.

Forget it, let's be stunned here.

I always feel that there is one more thing in my memory.

and many more!

Qin Guan remembered, before leaving, about the hunting fan anti-submarine aircraft!

Niu Guoren did not give the program source code, so that he could not integrate the system. Although he could find it through the system, he wanted this tone. At that time, I remembered to stop a few cooperation projects. Later, I didn’t ask about it and I didn’t know Niu Guoren. Have you succumbed?

Yes, I should ask, the people of Niu, think you are an empire that never sets. If you didn't continue to provide weapons to Silver Nation at the beginning, it was enough to give you face, but don't know what is good or bad.

Just when he was about to grab the phone, the phone rang.

"Hey, this is Qin Guan."

"Yes, General Zhao, what's the matter?"

"Really? Great, great, I must go, I will go right away!"

Putting down the phone, Qin Guan looked excited, great. After waiting for a long time, it finally arrived!

What are you waiting for?

Of course it is good news for the Navy! Another major event in 1982 was launching a launch vehicle underwater!

The last time I launched a launch vehicle to Hepingyang. At that time, the Navy sent a 580 formation, which was mighty and mighty, but unfortunately, they were all old Luda class. They were launched from land to sea to test the rocket's long-range capabilities.

And now, it is launched from underwater! It is called a launch vehicle, but in fact, it is the first submarine-launched ballistic missile, the Julang-1!

Qin Guan had been waiting for the good news a long time ago. How could he be missing from this important scene?
