Era: Starting from divorce from female college student

Moscow, Kremlin.

"So Yunlan City has other, even more powerful weapons? Or is this a fighter jet with a higher flight speed?"

Lermontov's expression changed instantly, his pupils dilating several times over.

It's really speechless.

No matter how invincible Yunlan City is.

There has to be a limit, right?

Is this never going to end?
When the news of the sale of Mach 5 fighter jets reached Moscow, Lermontov, Rokosov, Staros, and others were completely dumbfounded.

For neighboring countries such as the Saudi Empire, the Date Palm Empire, and the Persian Empire.

The stronger Yunlan City becomes, the better it is for its neighbors.

In any case, it's more convenient to buy weapons and equipment.

For example, Nasser Aziz, the eldest prince of the Saudi Empire, is practically begging Lü Yangui to be his elder brother.

Why?

Because Yunlan City is now beating Sam and kicking Moscow.

It can be described as incomparably powerful.

If they could gain the protection of Yunlan City, wouldn't the Saudi Empire no longer have to suffer from Sam's bullying?

But the more powerful Yunlan City becomes, the worse news it is for Moscow.

It's simply because Lermontov and his men want to get their revenge.

However, now such news has broken out in Yunlan City.

It seems that Yunlan City is hiding many secrets.

Even though Yunlan City has only been established for a few years, both Mach 5 fighter jets and laser directed energy weapons require an extremely powerful industrial system to manufacture.

The question is, how exactly did Yunlan City manage to do this?
This is a key issue that has baffled many countries around the world.

However, Yunlan City kept this a closely guarded secret, making it impossible for outsiders to know.

So what to do?

Let's keep looking; maybe we really can find it?
"That is indeed possible, and I suspect it would be a rotating detonation engine around Mach 16, or a scramjet engine. Only these two types of engines could potentially allow a fighter jet to exceed Mach 10."

One of the invited aviation experts, Kreoslov, said with a serious expression:
"Besides the possibility that this engine might pass wind tunnel testing and become a reality, they still have many core technological problems to solve, and it's unclear how they will overcome these challenges."

In Moscow, whether it's a rotary detonation engine or a scramjet engine.

Both of these engine technologies are still in the theoretical stage and have not yet entered the research and development stage.

Even engines like the sub-gas ramjet engine, which operate at speeds below Mach 10.

None of the major aero-engine research institutions in Moscow have been able to develop one.

Because the technical difficulty is too great.

The materials problem alone can give researchers a splitting headache.

Not to mention there are many technical issues related to flight.

And most importantly, Yunlan City has already applied Mach 5 engines to civil aircraft.

There are even more technologies in this area.

For example, noise problems, sonic booms, and so on.

The sheer number of technical problems is driving researchers to the brink of despair.

As it turns out, for the people in Yunlan City, it was as simple as eating and drinking.

They easily developed such fighter jets and civilian airliners, and they performed very well in actual applications.

It's really jaw-dropping.

People from all over the world gathered in Yunlan City, and many special agents also came over.

Many agents have already been discovered during airport security checks.

Of course, some agents were not detected because they were so well disguised.

However, all of their previous espionage operations had ended in failure.

Therefore, they all adjusted their plans this time.

Sam, Oak Ridge National Laboratory.

"You mean Yunlan City is selling Mach 5 fighter jets to foreign companies? Wow!"

When Dr. Cassie Mack learned of this news, he gasped in shock.

As a top aerodynamics expert within Sam, Casey Mack knew all too well what kind of existence the Mach 5 fighter jets of Cloud City truly were.

Their Oak Ridge National Laboratory has been researching this fighter jet for several years.

We still have no clue.

Although, theoretically speaking, they have already mastered some of the technical theories and technologies of the ramjet engine.

The problem is that the theory of ramjet engines already existed in the 1940s and 50s.

After more than 30 years of development, although there haven't been many updates to the theory, it's not entirely without direction.

The J58 variable cycle engine used in the previous Blackbird reconnaissance aircraft was a variant of the ramjet engine and the conventional jet engine.

Although in terms of speed, the Blackbird reconnaissance aircraft only had a speed of Mach 3.2 and could not maintain a long flight time.

Most importantly, the Blackbird reconnaissance aircraft also had many drawbacks, such as oil leaks.

However, the Mach 5 fighter jet that comes closest to Yunlan City is arguably the closest aircraft to it.

Before the appearance of the Mach 5 fighter jet in Yunlan City, the United States was the country with the fastest aircraft on the planet.

However, it's important to understand that the J58 variable cycle engine and the subsonic combustion ramjet engine are completely different concepts.

Dr. Casey Mack is the most qualified to speak on this matter.

"Yes, we had our suspicions when we heard the news, and we have already taken action."

Standing before Dr. Casey Mack was FBI Deputy Director Nick Hyton, who spoke with a serious expression:

"Therefore, Dr. Cassie, I hope your lab can expedite your research; it is extremely important for our country."

"How could I not know?"

At this moment, Cassie McIlroy almost swore:
"You need to understand that since the other party dared to sell Mach 5 fighter jets, they must have mastered even faster fighter jets."

"Furthermore, such a fighter jet will not be like the current Mach 5 fighter jets, but will be equipped with scramjet engines or rotary detonation engines, or even anti-gravity engines that we have never heard of before. In that case, the speed will exceed Mach 16, or even faster."

"How do you expect us to develop it? How do you expect us to catch up?"

"The materials technology, engine technology, and missile technology of a Mach 5 fighter jet are issues involving an entire industrial system. How are you expecting us to solve them?"

"It would take us at least five or six years to reverse engineer and produce a Mach 5 fighter jet, let alone break through to the Mach 16 level after we have fully digested and mastered these technologies."

"The most important point is that Yunlan City has been established for less than ten years, yet they have already produced so many amazing and groundbreaking technological products. Do you think that if they are given more time, they will be able to break through the limitations of Earth?"

Dr. Cassie Mack became more and more excited as he spoke.

He himself felt despair, let alone others.

However, as the deputy director of the FBI, Nick Hayden certainly wouldn't give up easily.

“Dr. Casey, I know you are having a hard time, but aren’t we having one too?”

"But please believe that the difficulties we encounter are only temporary. We will definitely overcome them and return to the top of the world once again."

Words of comfort do have a slight effect. Dr. Cassie Mack was less agitated, but he was still filled with despair.

After leaving Oak Ridge National Laboratory, Nick Hayden went straight to Taipei.

Unlike the fact that Great Britain sent people to Hong Kong Island.

After arriving in Taipei, Nick Hayden began his operation.

Nick Hayden came to this island to select suitable personnel to go to Cloud City.

Even though it's just a covert operation, it has to be done.

Yunlan City, the municipal government office compound.

Zhao Mancang sat in his office chair, listening to the work reports from Lü Yangui and the other responsible persons.

He couldn't help but have some doubts.

It's coming with force!
After Moscow's apology, the world appeared calm.

In reality, undercurrents are surging.

Everyone knows what's going on, but no one is taking the initiative to bring it up.

How are the plans for the weapons and equipment exhibition going?

Upon hearing Zhao Mancang's sudden question, Lü Yangui, Ye Liangsheng, Yuan Jigang, and other relevant officials were stunned for a moment.

Weren't we just talking about how to deal with those special agents who entered Yunlan City?
Why did we suddenly jump directly to the topic of exhibitions?
However, none of them were fools. Although they hadn't figured it out immediately, they were still answering Zhao Mancang's questions while thinking about it.

"Alright, now that the exhibition is almost ready, let's officially open it to the public in a week, on August 18th, and let everyone come and have a look."

After a pause, Zhao Mancang continued:

"This time, I suspect many of them will be buying Mach 5 fighter jets, so I must hold firm on the price and quantity offered to the public."

"Grumman, Sukhoi Aviation, Dassault Aviation, and other major international aerospace companies certainly want to acquire fighter jets and then conduct their own research and development and production."

"We'll refuse to let them have their way."

One measure is to restrict all fighter jets from being resold or 'disappearing' in other ways.

After all, those foreigners are quite cunning, so Zhao Mancang naturally wouldn't let them have any loopholes to exploit.

Secondly, if we want to purchase Mach 5 fighter jets, the quantity must be more than 30, and after-sales service must also be purchased.

We should treat everyone the same: either buy or don't buy.

Even a major player like the Saudi Empire needs to purchase thirty Mach 5 fighter jets and after-sales service.

These two requirements may seem few, but they are actually for making money in business.

In the original timeline, our country also wanted to purchase fighter jets in the early 1980s.

At that time, Dassault Systèmes of France actively promoted the Mirage 2000 fighter jet to us.

However, they refused to provide the two core technologies: engines and radar.

However, the price of twenty-four fighter jets was a staggering two billion US dollars.

That's really asking for the moon.

Now, Zhao Mancang is going to retaliate.

We also want Dassault Systèmes and other aircraft manufacturers to experience the pain of having their profits reaped.

Upon hearing this, Lü Yangui, Yuan Jigang, Ye Liangsheng, and others nodded with smiles.

"Boss, this is brilliant! They'll probably disagree, but whether they agree or not isn't important. It's best if they don't buy it and just watch others succeed."

Zhao Mancang just smiled.

He was already tired of hearing such flattery.

"By the way, how's the Olympic qualification process going?"

Suddenly, Zhao Mancang thought of something else and immediately asked.

For Yunlan City, the qualification to host the International Olympic Games is also a very important matter.

If Yunlan City can obtain the qualification to host such an event, it will be a qualitative leap forward.

"Boss, we're already actively communicating with the International Olympic Committee, so there shouldn't be any major problems."

Upon hearing Ye Liangsheng's response, the person in charge of the matter, Zhao Mancang nodded in satisfaction.

But he quickly added:

"However, you still shouldn't be careless. You must keep a close eye on things and make sure we can definitely host the Olympics in 1992."

In the original timeline, the 1992 Olympics were held in Barcelona.

Nowadays, in terms of both reputation and strength, Yunlan City is no less than Barcelona.

Although in terms of cultural heritage and other aspects, Yunlan City is indeed inferior to Barcelona.

But if the International Olympic Committee doesn't want Yunlan City to host the event, well, then Zhao Mancang will just do it himself.

Of course, it would be too difficult to organize such an international track and field event on one's own.

It's like hell mode.

It's almost impossible to do.

Even though great efforts can sometimes lead to miracles, there are some things that money simply cannot achieve.

In short, just keep striving in this direction.

"Also, you need to hurry up and continue to accelerate your progress in football and basketball."

Zhao Mancang urged.

Yunlan City is a newly established city.

It is actually a country, but it has not yet been officially established.

But it already possesses almost everything a country should have.

All that's missing now is a title, that's all.

The total population of Yunlan City is now rapidly approaching 20 million.

In order to enrich everyone's spiritual and entertainment life, Zhao Mancang did everything he could.

Life lies in movement!

As Yunlan City's economy develops at an increasingly rapid pace, everyone is becoming wealthier.

Then some things need to change.

This is why Zhao Mancang was so eager to apply to host the Olympic Games and vigorously develop cultural and sports undertakings.

People tend to cause trouble when they have free time.

Even ordinary residents of Yunlan City do not possess firearms.

However, there are still many deadly weapons in life.

He hoped that everyone could live and work in peace and contentment, rather than having their lives taken away by sudden accidents.

Just as Zhao Mancang and his group were about to end their meeting.

Lu Yangui's secretary suddenly knocked on the door and came in.

It turned out that he had received a phone call from Sam's White House.

Reagan wants to come to Yunlan City! (End of Chapter)
