When Wang Dong came to the president's office, Serena was talking to someone on the phone, using a landline.

It was a company phone and was only used for business purposes.

“…… Tomorrow at 8:30 p.m....... Okay, no problem, be sure to be on time. ”

"Lawrence?" Waiting for Serena to put down the microphone, Wang Dong asked.

Serena nodded and said, "It's his secretary who invited me to London to say that there is a very important charity party tomorrow night." ”

"How important?"

"Among the guests, in addition to the well-known figures in the British business community, there are many political leaders, and maybe the owner of 10 Downing Street will also go."

"So Lawrence already knows what we're going through in Saudi Arabia."

"When he came back, he was targeted by MI5's people, and it was normal for him to know."

Wang Dong smiled and said, "I talked to Zhao Yu, and he is confident that he will design a small-caliber rifle cartridge with performance no worse than Textron's 8mm countersunk cartridge, and will make a batch of sample bullets. If the timing is right, see Lawrence tomorrow and you can have a showdown with him. ”

"So fast?"

"We're running out of time."

Noticing Wang Dong's serious expression, Serena sighed secretly.

In Riyadh, Wang Dong told her, so Serena understood the meaning of this sentence.

In addition, being targeted by MI5's agents after returning has confirmed Wang Dong's worries.

In fact, it is inevitable that they will be investigated by the British intelligence and security agencies, and it has nothing to do with what Wang Dong did in Saudi Arabia.

The point is, BAE Systems is a British arms giant.

After Serena offered Lawrence to cooperate and mentioned that D&F was developing a headshot, the British intelligence and security agencies would launch an investigation.

It's just that MI5 is only targeting Serena now.

Although Wang Dong covered up Serena's identity through legal channels and did not use the resources of the Military Intelligence Agency, there must be flaws, and it is by no means perfect.

As long as MI5 investigates deeply, it can be found that there is no such person as "Katherine Stuhl" at all.

Of course, this will take time.

After discovering that Serena was using a fake identity, MI5 investigates D&F, focusing on its partners.

At this point, it is only a matter of time before Wang Dong, Luo Qing, Zhao Yu, Gao Jun, Musharraf, Nicholas and Churkin are found.

Subsequently, the British intelligence and security agencies will find that the "Angu" company is also under the names of Wang Dong and others.

Although Wang Dong has a British passport, and other people have similar identities, their appearance has not changed, and they can be seen at a glance.

The key point is that, apart from the United States, only China is developing a submerged bomb.

As long as the British intelligence agencies are suspicious of D&F's technology, they will associate Huaxia with Wang Dong and others.

It may take months, if not years, to find out the relationship between Wang Dong and the Military Intelligence Agency, but as long as there is doubt about Wang Dong's origins, the British authorities can find any reason to close down D&F and impose strict restrictions on business activities related to Wang Dong and others.

At this point, there is no place for D&F companies in the entire Western world, let alone the UK.

You must know that as long as it is determined that Wang Dong is a Chinese or a big boss of D&F, the Western countries that signed the Wassenaar Agreement will follow in the footsteps of Britain.

Obviously, this is the reason why Wang Dong asked Zhao Yu to develop a small-caliber submerged bomb first.

As long as Zhao Yu's judgment is correct, there is no place for small-caliber rifle cartridges in the future firearms market, so there is no concern about leaking trade secrets by providing a small-caliber countersunk bullet to BAE Systems to participate in the bidding of OIC projects.

As for military secrets, even more so to worry about.

Don't forget, the MIA doesn't provide the formulation and chemical production process of the binary propellant, so it does provide the technology of stacking spray filling.

All the bullets used for the test were handmade, and the method of making them was in the hands of a few technicians.

In addition, the propellants used to make test bullets all came from China, were obtained through smuggling channels, and were also supplied in limited quantities by MI.

Even if some propellants were obtained, there was no recipe for them, and there was no way to know the proportions of the various ingredients.

In fact, there is another key accessory in the hands of the Military Intelligence Agency, which is also available in limited quantities and cannot be obtained by disassembling the bullet.

This is the indispensable layer primer.

"Primer" is just a colloquial term, strictly speaking, this is the real "high-tech".

Not to mention Zhao Yu, even Chen Zihao does not know the composition of this "primer", only knows that its core material is a polymer compound developed by Huaxia.

Because this polymer compound is very easy to oxidize, even if it is only exposed to air, it will oxidize immediately, so it can only be stored in vacuum, and it must be soaked in a special solution when assembling, or carried out in a vacuum environment, which has extremely high requirements for the operating environment.

Of course, this is also the most effective means of confidentiality.

As soon as the bullet is disassembled, the polymer compounds that make up the "primer" will oxidize.

Even if the operation is under vacuum, that is, during the assembly process of the bullet, there must be a small amount of air in the cartridge case, and the "primer" is wrapped in a propellant, and there is no air basis in the cartridge case, as long as the integrity of the cartridge case is destroyed, it will inevitably come into contact with the air.

It is precisely because of this that the Military Intelligence Bureau can confidently and boldly provide Wang Dong with the "primer".

Of course, they are all stored in vacuum, and only Chen Zihao and a few other technicians appointed by the Military Intelligence Bureau have mastered the assembly method of the "primer".

In addition, "primers" are available on demand, and D&F can supply as many ammunition as it produces.

Because "primer", to be precise, that kind of polymer material is the core technology, so only Zhao Yu knows, and even Wang Dong has never heard of it.

Of course, Wang Dong usually only asks about technical things, and it's okay if he doesn't tell him.

The small-caliber countersunk was first developed only to whet the appetite of BAE Systems, by cooperating with BAE Systems to cope with the investigation of the British intelligence and security agencies.

As paradoxical as it sounds, as mentioned earlier, it is because of the cooperation with BAE Systems that it is under investigation.

Actually, herein lies the subtlety.

As long as BAE Systems believes that D&F has mastered the technology of producing submerged bombs, even if it knows that this technology comes from China, and even knows that Wang Dong was a super agent of the Military Intelligence Agency before, in order to win the OIC project, in order to grasp the power to formulate NATO standards, and for the sake of the hundreds of billions of dollars in the market and amazing profits in the future, BAE Systems will definitely maintain D&F before getting what it wants.

BAE Systems is a British arms giant with inextricable ties to the government.

In addition, whether or not it can win the calibration right of the third-generation standard caliber is also linked to Britain's national interests and is also related to Britain's face.

To be maintained by BAE Systems, and to gain the tacit approval of the British authorities, it is necessary to come up with real materials.

If you choose one of the three, it will definitely be a small-caliber headless bomb with no future.
