Legend has it that a butterfly in the Amazon rainforest can whip its wings a few times and cause a tornado thousands of miles away in two weeks.

The world is a huge chaotic system, and a small change, gradually accumulating, can also have a huge impact!

Since Zhang Xingyang returned to this world at the beginning of 96, four years have passed since the upcoming millennium.

Under Zhang Xingyang's interference, the world has changed dramatically.

The first to change its fate was the 703 factory, which was about to close down in the wave of marketization, because the products could not catch up with the pace of the market.

In the process of national development, this kind of thing is very common, even large enterprises with a net worth of billions of dollars may collapse and go bankrupt overnight.

Not to mention Factory 703, such a small factory that was not very good in the first place.

If Zhang Xingyang does not appear, then his biggest possibility is to slowly decay, drain the last drop of blood, and then collapse in the back waves of the times.

Zhang Xingyang's rebirth was the first thing to change was the fate of Factory 703.

After completing the transformation and technical upgrading of the production process, it generated hundreds of millions of net profits for the first time!

In the future, it became more and more exaggerated year by year, and by 99 years, the profit was close to three billion!

After dealing with the corruption problem of the 703 factory, Zhang Xingyang once had a conversation with Hu Deming, the former director of the 703 factory.

"Lao Hu, I know about this incident, you must not be involved."

"But, as the factory director, did you really not find any signs at all?"

"Still, you found out, but you want to shield them."

The gap between the two is huge, one is just a simple dereliction of duty, and the other is serious.

That means that Hu Deming, as a senior manager, has problems with his basic literacy.

Lao Hu's face was very unsightly at that time, and Zhang Xingyang could see that this middle-aged man, who looked like an old farmer, revealed a thick depression.

At that time, the two of them were talking outside the old factory building of Factory 703.

Hu Deming looked up at the camphor trees that were still green on both sides of the road inside the factory.

After a while, he said in a voice that was already hoarse:

"Dean Zhang, I have always been very grateful to you."

"If you hadn't suddenly appeared, we had transformed our production processes and production lines, and had conducted a series of trainings for our original employees."

"Let's produce materials that are so good."

"We probably would have gone out of business that year."

Speaking of this, Hu Deming bowed slightly to Zhang Xingyang.

"Thank you!"

Zhang Xingyang could feel that when Hu Deming said this, he was not patting himself.

This honest-looking middle-aged man is grateful from the bottom of his heart to Zhang Xingyang, who saved the fate of the factory that was about to go bankrupt.

After bowing first, Hu Deming seemed to remember the past.

"When the efficiency of the factory was not good, we all tried all kinds of ways to save the factory that was getting more and more difficult."

"At that time, everyone was really thinking about the factory."

Speaking of this, Hu Deming's mood suddenly collapsed, and he choked up when he spoke:

"But why is everyone like this now!"

"Lao Sun, when the efficiency of the factory was not good, he still took the lead in not asking for wages."

"How did this happen now!"

Lao Sun was the financial officer of the original factory, and in the corruption incident of the factory, he embezzled nearly 10 million yuan, and a large part of it was the welfare funds of employees, which he ate into his stomach.

Zhang Xingyang also knew for the first time that the person who was almost the most corrupt in the corruption incident had a clean side.

Maybe Lao Sun had a good relationship with Hu Deming, and he once had an experience of sharing hardships.

However, people can change, especially when tempted by money.

As a financial officer, Lao Sun passes through hundreds of millions of dollars from him every month.

Perhaps, under the temptation of money day after day, his heart has changed that he has not even felt.

At first, it was just thousands of dollars of leftovers, but after finding that no one had found out, I became more and more bold.

From thousands, to tens of thousands, to hundreds of thousands, to eventually millions.

It just took less than a year.

Factory 703 generates billions in revenue and profits every year.

This time, if they hadn't been so bold as to swallow the entire factory, no one would have found out for years.

Hu Deming was so broken that he covered his face and was already crying.

Judging from Hu Deming's performance, he really doesn't seem to know that much about this matter.

Zhang Xingyang's judgment of people's hearts is not so accurate.

But Hu Deming doesn't seem to be the kind of existence that acts like a god, so it's all his true feelings.

Therefore, the appearance of Zhang Xingyang really changed the fate of many people.

Taking Lao Sun as an example, if there was no Zhang Xingyang, he might have been accompanying the slowly dying 703 factory and leaving a good name of his own.

But now, he has only left everyone with a greedy image, and has brought himself more than fifteen years in prison.

However, Zhang Xingyang's appearance also saved hundreds of workers in the original 703 factory.

And because of the expansion of the factory, it directly led to the employment of thousands of people in Shonan.

Indirectly affected the employment of tens of thousands of people, after all, the wages in factories are high, and thousands of people need to spend.

In these years, there is no e-commerce, and everyone can only spend money locally.

This has led to the development of catering, tobacco and alcohol, entertainment and other industries.

Now when it comes to Shonan, the first thing that comes to everyone's mind is the 703 factory.

This is also one of the things that made Zhang Xingyang the happiest since his rebirth.

Relying on their own efforts, they have greatly changed the economic fate of a place and made everyone live a better life.

In addition to the fate of the 703 plant, the second change was the original ill-fated domestic aircraft engine WS-10.

WS-10, the first domestic attempt to produce an advanced aero engine.

Because there are many technical difficulties, in the previous life without Zhang Xingyang's help, it was not until 05 that WS-10 began to equip troops in small batches, and in the process of equipment, many problems appeared one after another.

Whether it is a turbine disc or an engine blade, there is a big problem in the material.

If it weren't for Zhang Xingyang, when he was carrying out the research and development of rocket engines, he would have completed the preparation work.

It will take at least seven or eight years for the WS-10 engine to officially enter the practical stage.

It was also because of the early completion of the WS-10 engine, which had a series of subsequent effects.

The first thing that will be affected is the finalization of the Jian-10 fighter.

Originally, the J-10 fighter was prepared to use Maozi's AL-31F engine.

Not to mention expensive, the most important thing is the lifeblood of the fighter, which is controlled in the hands of others.

As soon as there are any fluctuations in the relationship between the two sides, there will be problems with the supply of engines for fighters.

And even so, the AL-31F engine provided by Maozi still has a lot of problems.

At the beginning of the design of the J-10 fighter, it was envisaged to use the domestic WS-10 engine.

After the AL-31F was replaced, the structure of the fighter needed to be adjusted a lot in order to adapt to it.

This also led to the fact that in the original time and space, the service time of the J-10 fighter was delayed for a lot of time.

And after Zhang Xingyang solved a series of problems with the engine, the WS-10 was successfully installed on the J-10 fighter.

This led to the first flight of the J-10 fighter being advanced by a whole year, and because of the better adaptation.

The J-10 fighter does not have as many problems as imagined.

After the first flight, finalization was quickly completed.

After Zhang Xingyang put forward a lot of advanced experience in aircraft production.

Chengfei has completed the transformation of several production lines, and the annual output of Jian-10 fighters has increased to the level of two or three hundred compared with the original dozens of fighters.

And after using the large carbon fiber produced by the 703 factory to make the vertical tail and wing of the fighter, the performance of the fighter has been further improved.

After upgrading the avionics and radar systems, this wave of J-10 fighters is now the largest number of J-10A.

As for the J-10S, it should not have been a product of this era.

Whether it is supersonic cruise, over-the-horizon air combat or semi-stealth combat, it is not what third-generation aircraft should do.

This is also why, after the first J-10S completed production, even Zhang Xingyang was shocked.

You must know that at this time, there are still six years before the world's first fourth-generation aircraft is officially put into service!

It can be said that if it weren't for the fact that the stealth problem was not taken into account at the beginning of the design, and an external pylons were used, there would be no way to achieve complete stealth.

The J-10S, in fact, can already be regarded as a fighter stepping on the threshold of the fourth-generation aircraft.

Of course, if Zhang Xingyang and Song Tianxing are a little thicker-skinned, like some countries in later generations, they insist on saying that the fighter using external pylons is a fifth-generation aircraft (Russian standard), there is no problem.

It can even be said that in this era, such remarks are more acceptable to everyone.

After all, at this time, everyone has not seen the real fourth-generation aircraft, just from the paper data, the J-10S is indeed a big cut above the previous third-generation aircraft.

It can even be said that the terrifying performance of the J-10S has allowed the domestic air force to see for the first time the power of a fighter capable of stealth over-the-horizon combat.

Ordinary third-generation aircraft, in front of it, basically does not have any power to fight back.

In the previous battle for the Golden Helmet, there was an almost desperate 32:1 battle loss ratio.

In other words, if you want to destroy a J-10 S, you need to pay 32 J-10A fighters with advanced performance!

This is still the case when the J-10S has exhausted all the air-to-air missiles and can only carry out cannon dog fights.

If the J-10S can return to replenish ammunition, it is hard to imagine how much the J-10A fighters will have to pay to be able to shoot them down!

This is just a J-10S with one foot on the threshold of the fourth-generation aircraft!

The real fourth-generation aircraft has more terrifying performance, higher combat altitude, faster speed, more perfect stealth function, and stronger missiles!

This is also why, after the battle for the Golden Helmet, everyone's attention to the fourth-generation aircraft has been mentioned to an almost exaggerated degree.

According to Zhang Xingyang, the fourth-generation aircraft project, which was originally progressing slowly, has now begun ground static testing, and the progress can be said to be rapid.

In terms of advanced fighters, although other countries are currently paying attention to the Dragon Kingdom, they still don't take it to heart because of the long-term stereotype.

What really makes Eagle Sauce, or other countries, a headache, is the sudden leapfrog development of missiles in China in recent years.

From long-range guided mushroom-headed ballistic missiles, to supersonic rockets with a range of nearly 600 kilometers, to air-to-air missiles with an interception range of 500 kilometers.

These will make the backbone of this country more and more hard and more confident!

Here, some Zhang Xingyang was not directly involved, and some were developed by himself.

Although even without Zhang Xingyang's participation, they still have to develop, but how many detours and how much time we waste in the process!

Moreover, according to the information obtained by Zhang Xingyang, Eagle Sauce actually mistook their rockets for hypersonic anti-ship missiles.

Although they really have such a development plan, it was really only a rocket that was tested!

After issuing a condemnation, Eagle Sauce also announced that they will also work on a hypersonic missile!

However, with Zhang Xingyang's understanding of Eagle Sauce, it is estimated that it will be difficult for them to complete the research and development of hypersonic weapons.

After all, it was not until thirty or forty years later that the Dragon Kingdom was about to complete the research and development of almost all versions of hypersonic weapons, and Eagle Sauce finally completed the development of its first air-launched hypersonic missile.

At their speed, if they want to catch up with themselves, unless they also have reborn, it will not be possible in three hundred years.

Mainly because Eagle Sauce has no way to spend a lot of money to build a hypersonic wind tunnel.

And now there are two wind tunnels in the Dragon Country with more than ten times the speed of sound alone.

The future development of the two sides is almost clear at a glance.

And that's just a change in weapons.

The biggest change is still Zhang Xingyang's old profession, the aerospace industry.

Originally, it had to go through a lot of changes before it was able to re-emerge.

Under the leadership of Zhang Xingyang, it only took a year to adjust its own state and complete several rocket launches.

The most powerful thing is that under such conditions, Zhang Xingyang also led everyone to complete the research and development of a new recyclable rocket.

The Hongyan series of rockets was developed.

It indirectly affected the construction of the entire domestic communication system, and the construction of a low-orbit satellite communication system began.

Although the second phase of construction is still underway, a large number of satellites have begun to go into space to play their role.

At present, the launch of at least 1,000 satellites has been completed, and although there is still a certain gap between the final goal of 4,000 satellites in the second phase of the project, it has been able to share a large part of the communication needs.

It has reduced the pressure on the construction of ground base stations and played an important role in several disaster relief efforts.

This is also where satellite communication systems are better than terrestrial base stations.

Except for high-energy rays in space, satellites are very susceptible to other natural conditions.

Unlike ground base stations, they cannot work in the event of floods, earthquakes, fires, mudslides, etc.

For some remote areas where the situation is relatively poor, the user experience is better.

Moreover, the entire project of the low-orbit satellite communication system requires a large number of outstanding talents, and a lot of outstanding talents have been absorbed from the major universities and scientific research units in China.

To a certain extent, the loss of high-end talents has been avoided.

In terms of the aerospace industry, Zhang Xingyang has made a major change in the manned program.

The manned rocket has been replaced by the current Hongyan rocket from the original Long 2F rocket.

The carrying capacity has been greatly improved, and a lot of scientific research equipment has been added, which can do more experiments.

Moreover, Shenzhou 2 will be able to add more experimental instruments and will be in orbit for a longer time.

Because of Zhang Xingyang's existence, the aerospace industry has entered the fast lane of development.

It can be said that Zhang Xingyang has only been reborn for less than four years, and a lot of changes have taken place in this country and the world.

As for the good things about these changes, it is natural that future generations will comment on them.

People who live in this day and age just want to do their own thing.

But do good deeds, don't ask about the future!
