Dong Shengjie is half a military fan, and when the helicopter flew overhead, he immediately recognized the Middle Eastern version of the Wuzhi-20ME made in China at a glance.

The Wuzhi-20ME can carry 2,200 kg of ammunition, including 72 Red Arrow series anti-tank missiles, a 30mm machine gun, bulletproof glass to resist 15.7mm ammunition, and is also equipped with a radar system and early warning system, automatic target warning, including laser ranging and friend or foe identification system.

Such a helicopter gunship costs as much as $35 million per unit.

Looking at the $175 million whistling through the sky... Five armed helicopters, Dong Shengjie was stunned, is this a big man visiting the base?

When Dong Shengjie rushed back to the underground center of the main control building that had just been built, he knew that it was Chen Xu who came.

Dong Shengjie was taken aback.

Chen Xu's current identity is not trivial, if Mi Guo knew that he was coming to Botswana, he would definitely arrest him at all costs, or even kill him.

It was so bold that he dared to run to Africa in such a swaggering manner.

After the person in charge of the base and several experts left the conference room, Dong Shengjie went in and asked, "Why is Mr. Chen free?"

"I'm tired of staying in the country, so I come out to breathe. Chen Xu said with a smile and handed Dong Shengjie a cigarette.

Although Dong Shengjie didn't believe that it was as simple as just breathing, he didn't ask any more questions, there are some things that he can't know and should know as a small person.

After taking the cigarette, he helped Chen Xu light it, and then sat down with him and pulled up the parent's short. This is also the only thing he can do now, after all, time has passed, and everyone's identities are too far apart.

After chatting for less than three minutes, as soon as the cigarette in his hand was halfway smoked, a group of gray-haired experts came in, and Dong Shengjie immediately snuffed out the cigarette and stood up.

"Hahaha, Dr. Chen came early as he came, and I just have a question I want to ask you......

What Dong Shengjie didn't expect was that Chen Xu came all the way from China to Botswana, but he stayed for less than half an hour before leaving.

It was also from this day that Dong Shengjie never had the opportunity to chat face-to-face with Chen Xu in the following years.

It wasn't until a year later that he learned that Chen Xu's visit to Africa was mainly in neighboring Zimbabwe to discover a very special metal - NB717, which can be used to make high-quality superconducting materials.

……

Chen Xu did not stay in Zimbabwe for a long time, staying for less than 48 hours in total, before returning to China.

It's not that I'm afraid of what the United States will do to him, in fact, from top to bottom, the United States government, like the White House, the Pentagon, the FBI, the CIA, Area 51, etc., any action they take, any instruction they issue, including every word they say, is all under Xiaobai's control, and it is simply a fool's dream to secretly arrest him.

What's more, he is worth to the point where he has the energy that is far from what ordinary people can imagine, as can be seen from the fact that there are five armed helicopter escorts on the trip, as long as you don't go to the mainland of the United States to hang around, you don't have to worry about personal safety at all.

The reason why it came and went in a hurry is that the 10nm lithography machine has finally been successfully developed.

The 10nm lithography machine produced by XHZZ (Vimicro Equipment Co., Ltd.) is no different from the 10nm lithography machine in the Netherlands in terms of accuracy.

However, Chen Xu has designed a set of AI intelligent module groups, including light source equipment and lenses, all of which have been improved, which can be used to manufacture AI chips in the true sense.

The main difference between the AI chip and the traditional chip is that it not only has a smart "brain" CPU, and a GPU for image rendering, but also integrates DSP (digital signal processing) and large-capacity memory.

Because of this, although it is only a 10nm process, its expressiveness will theoretically exceed that of the 7nm process.

AI chips will be the most powerful chips before the birth of biochips, and there is no one.

Not surprisingly, the advent of AI chips will completely change the future of the world's semiconductors.

China Shipping Free Trade Zone.

In the super-large dust-free workshop, Chen Xu and Zhang Haichun, the person in charge of XHZZ, sat in front of the huge screen and watched the rolling data, while behind them was a circle of siege lions wearing dust-free suits, with an average age of no more than 30 years old, and everyone dared not gasp.

Twenty minutes later, when he saw that the simulator's evaluation of the yield rate of the lithography machine exceeded 97%, Chen Xu nodded and smiled with satisfaction: "Well, this yield rate has greatly exceeded my expectations, not bad!"

Hearing his words, the originally stagnant air suddenly relaxed, and everyone's faces couldn't help but show joy.

"Great~"

"yes......"

Chen Xu stood up and said with a smile: "Let's officially produce according to the plan!"

Zhang Haichun smiled and said, "Okay, Mr. Chen." SMEE......"

The two of them chatted as they walked towards the door of the laboratory, and a large group of people gathered behind them gave way.

When he was about to walk to the door, Chen Xu suddenly stopped, turned his head to look at the more than thirty young doctors in the laboratory, and said with a smile: "Each person will be rewarded with 5 million!"

After speaking, Chen Xu turned around and left.

A group of siege lions in the laboratory were stunned by the sudden surprise, and everyone didn't react for a while.

Under Zhang Haichun's reminder, everyone shouted excitedly: "Thank you, boss~"

"Boss, you are the most handsome......"

The salary of the siege lion is much lower than that of those engaged in IT and finance, and there is no opportunity to make extra money in ordinary times.

I never thought that Chen Xu, the boss, would be so inhumane, and as soon as he made a move, each person was directly 5 million, and he was about to catch up with the prize money of the highest award in science and technology, so he was naturally excited.

Over there, Chen Xu waved his hand without looking back, and left with a smile on his face.

Although these doctors did not play much of a role in the study of lithography machines, he had to create a lithography machine that was made by the concerted efforts of everyone, so the reward should be awarded.

……

……

Time flies, and more than half a year has passed in a blink of an eye.

With the successful development of the 10nm lithography machine, various technologies in other chip manufacturing have made breakthroughs, such as high-purity chemicals styrene, divinylbenzene, high-purity stainless steel reactors, fluorinated polyimide, photoresist, hydrogen fluoride and so on.

At the same time, under the reverse thrust of the powerful star system, Xinghai Technology has made unimaginable technological breakthroughs in biology, chemistry, materials, physics and other aspects.

One of the most important is the biopharmaceutical aspect.

Anyone who has watched "I Am Not the God of Medicine" should know how huge the price gap between Chinese and foreign drugs is?

However, the movie did not tell the audience that behind the disparity in drug prices, it is actually the research and development of domestic drugs that lags behind foreign countries in terms of equipment, raw materials and preparation processes.

The preparation process of many drugs in hospitals is actually a technology that was eliminated by foreign countries decades ago, and even so, it is necessary to pay expensive technology patent fees to foreign pharmaceutical giants every year.

As for the preparation process of those special drugs and targeted drugs, they are not disclosed to China at all, and patients can only spend several times or even dozens of times the price of foreign patients to buy finished drugs.

Or, like Cheng Yong, a health care product vendor in the movie, went to India to smuggle affordable drugs.

Nowadays, under the reverse thrust of the Xingchen system, Xinghai Technology has mastered the preparation process of targeted drugs for dozens of malignant tumor diseases defined as terminal diseases, such as liver cancer, lung cancer, pancreatic cancer, breast cancer, cervical cancer, etc., as long as the drugs developed by Xinghai Technology are taken, the spread of cancer cells can be completely inhibited.

In addition, dozens of chronic diseases such as heart disease, diabetes, and high blood pressure have been solved.

However, these messages have been blocked for the time being, and they need to be announced slowly.
