"Let's start with the miniature, efficient and high-resolution electron microscope we need." He Xingzhou said, "While studying the lens, we also solved the optical problems of genetic engineering instruments."

Academician Pan Yan has mentioned to him many times that without sophisticated genetic engineering equipment, it is impossible to detect the genetic information of the Zerg.

A year ago, it would have been difficult to manufacture this thing because they had to face problems in materials, manufacturing levels, design, and image algorithms.

In this year, He Xingzhou's various technological reserves have solved three major problems.

Materials, China has been able to manufacture top-quality glass and related materials;

The manufacturing level and the processing level of Longteng machine tools can be used to polish the lenses of microelectron microscopes, and can be used to polish the lenses of space telescopes and nuclear fusion power generation devices!

The image algorithm was also perfected by He Xingzhou not long ago.

The only problem is the design!

And He Xingzhou has just unlocked the structural diagrams of a hundred optical instruments from the quantum optical brain. As long as he is given a certain amount of time, he will definitely be able to complete it!

While He Xingzhou led his team to focus on researching optoelectronic instruments, the outside world and the public were still paying attention to the game "Wukong". It gained a good reputation and became the best-selling stand-alone game in the world in just one month. Over 50 million copies sold!

Thirty percent of them are foreign players!

As a result, major game manufacturers have announced that they have purchased the license for the "Qiankun" physics engine and will produce related games.

There is also news that the seven countries are about to hold a forum to discuss development issues.

This forum has not yet started, but all parties seem to have started some new small actions.



Light Country, Hillsboro, OR, FEI Corporation.

This is a company that manufactures and operates a variety of scientific instruments and provides world-class microscopy solutions to the global nanotechnology community.

The transmission electron microscope produced by it is one of the indispensable equipment for life science research.

"Mr. Taylor, we have paid a 30% deposit in advance. When your company's products arrive, we will pay the remaining 70% in accordance with regulations." Xu, a buyer from China, the company's business department Bo was speaking in fluent English with Taylor, a senior president of FEI.

Taylor smiled and said: "Of course there is no problem. The transmission electron microscope you customized has been completely manufactured. Once the export review is passed, we will ship it immediately!"

"I wish us a happy cooperation!" Xu Bo shook hands with him, and he felt relieved.

He is the head of a medical technology research institute and comes here to purchase transmission electron microscopes for life science research.

Of course, this is only his superficial identity. Xu Bo's true identity is the third-level executor of the Xuanwu Project.

For the research on Zerg, the team encountered very big obstacles in terms of instruments and equipment. Relevant high-end equipment is not available, so they can only focus on related parts.

These days, Xu Bo and other teams traveled to various countries, but failed to buy the products as they wished. For example, there are only three companies in the world that can produce high-end transmission electron microscopes, two of which are in Sakura Country.

They originally approached Sakura's manufacturer, but the manufacturer directly rejected their purchase request.

In desperation, through various relationships and a 300% premium, they reached an agreement with FEI to purchase some transmission electron microscopes that were not the most advanced.

Xu Bo didn't know that even though he was very careful and disguised himself as an ordinary purchaser, his purchase list still reached the intelligence center of the Deng Kingdom.

"This Oriental man purchased a large number of high-end transmission electron microscopes, which are suspected to be used for life science research." The intelligence officer reported the list.

"Life sciences?" In recent times, they have been very sensitive to life sciences.

It is said that because many mutated creatures have been discovered recently, the higher-ups have ordered that all related technological trends must be monitored.

"They have been looking for related instruments and equipment, and the purchase of a transmission electron microscope should be one of them."

"Can't sell!" The review officer stamped a red seal of rejection on the sealing place.

The subordinate said: "This order is FEI's largest order this year. If they reject it, they will be very dissatisfied. Moreover, the order as a whole is in compliance with regulations."

The review officer glared at him and cursed: "You can't sell this kind of thing no matter how much money you pay! As for the reason, do you still need me to teach you? Just find an excuse and you'll be stuck."

"Yes." The subordinate understood instantly that his boss's words meant that he could withstand the pressure of FE Company. As for excuses, just make up any one.

Xu Bo got bad news before he returned to China.

"Mr. Xu, the thing we bought is stuck, and it is said to involve a certain restricted technology..." After the entourage finished speaking, Xu Bo frowned.

"We finally bought it with great difficulty. If these instruments cannot be shipped back, we will hinder the Xuanwu Project!" an accompanying person said anxiously.

"Yes. These transmission electron microscopes can be used on at least dozens of high-end instruments. We must not let anything go wrong here!"

"But this is other people's territory, and if they don't sell their things, what should we do?" someone asked.

Xu Bo said: "We alone can't do it. Contact FEI. If these things are released, they will also suffer huge losses. Let FEI put pressure, and there may be a chance."

"Yes, we are not the only ones who are anxious. FEI will also face huge losses, and their words are more effective than ours here."

Xu Bo immediately contacted Taylor, and just as he thought, Taylor was also extremely anxious.

If the relevant departments suddenly issue a ban, they will suffer huge losses.

He assured: "Don't worry, our company has requested a review. It has not been clearly stated that this is a problem with the order. There is still a chance!"

Xu Bo and others are also working on it, but they have encountered too much resistance and have made no progress.



Within the institute, He Xingzhou is designing an angstrom-level transmission electron microscope.

One angstrom is equal to one-tenth of a nanometer, ten to the minus tenth power of a meter!

Currently, most of the trap transmission electron microscopes in the world are at the micron level, and the most cutting-edge ones can reach the sub-angstrom level.

"Traditional optical microscopes cannot see 0.2 micron ultrastructure clearly because the wavelength of visible light is too long. The wavelength of the electron beam is much shorter than that of visible light, and the higher the voltage, the shorter the wavelength."

He Xingzhou looked at his computer, which had drawings for five parts, including lighting system, imaging system, vacuum system, recording system, and power supply system.

Most of them can be designed by the team. The most difficult part is the electronic lens part, which involves multiple systems.

"Vacuum electron gun, condenser, sample chamber, objective lens, diffraction mirror, intermediate mirror, projection mirror, fluorescent screen and camera." He Xingzhou further subdivided the electronic lens and began to design it one by one.

"The electron gun actually heats the filament. When the heating current passes through, the filament will emit electrons. The arrow-axe or point-shaped filament beam tip is more concentrated..."

This is a very brain-burning process, and the design of each structure requires a lot of thinking and calculation.

While he was working, Luo Zhenhai was leading people to conquer microelectronics, micro-sensors and other technologies to improve smart glasses-related technologies; while Yan Rui's team was working on optical lenses and optical sensor technologies, including a multi-photon laser scanner. The microscope technology is an improved version of He Xingzhou's original two-photon laser scanning microscope technology.

This microscope can be used in life sciences to observe brain slices, embryos and organs.

Compared with the angstrom-level transmission electron microscope designed by He Xingzhou, the optical lenses required for smart glasses are a minor problem.



One month passed quietly, and there was only one month left before the Seven-Nation Forum.

In other countries, Xu Bo's team has exhausted all methods, including formal channels and connections, but with little success.

The transmission electron microscope they purchased has been detained at customs and cannot be returned to the country.

"Mr. Simon, you have been reviewing our procurement materials for a month." At the relevant units, Xu Bo argued, "We have submitted all the documents and information you asked us to submit. All procedures are legal and compliant. We require Return the goods we purchased immediately!”

Simon, the person in charge, looked at these Orientals with a cold expression and said: "Whether it complies with regulations or not is not up to you, but it has to be inspected by us!"

"We haven't finished checking yet, so please be patient and wait."

He didn't care what Xu Bo and others said. It had only been a month, so what was the rush? It will take at least a few years!

"Mr. Simon, what you have done has seriously damaged the interests of our FEI company!" Taylor was also very unhappy about this. "If it is not resolved within ten days, I will file a complaint with the Industry Management Association!"

When it comes to Taylor, Simon's attitude is much better.

He smiled and said: "President Taylor, don't worry, we are also actively testing and studying the problem, and coming in will not cause losses to your company. Then you can come again in ten days, and we will conduct a review meeting and make a decision."

Taylor snorted: "I hope so!"

In a capitalist society, the power of these capitalists cannot be underestimated. If FEI cannot be appeased, they will also face tremendous pressure!

Nine days later, FEI Corporation.

Taylor met with Simon before the review meeting.

Simon opened his mouth and said: "This batch of instruments cannot be sold to China."

"What about our company's losses?" Taylor asked.

"Don't worry. Although we can't sell them to China, we have found other buyers for you. Recently, companies in Sakura and Korea are planning to order a batch of transmission electron microscopes. We can act as a middleman for you to sell these products. This way, you are compliant and don’t suffer losses,” Simon said.

FEI's pressure still had an effect, but their solution did not take Xu Bo and others into consideration.

"What about our company's reputation?" Taylor asked.

"Don't worry, this is something that can't be helped. No one can say anything. And I can tell you clearly that in the future, there will be no customers from the East for this kind of instrument." Simon said.

His words meant something, and Taylor probably got it.

After weighing the pros and cons, he agreed: "Okay, then I'll do as you say!"

Simon smiled and said, "President Taylor must know how to handle tomorrow's meeting."



The next day, Xu Bo and others met Simon and Taylor again.

Compared with the anxiety and uneasiness before, the expressions of Xu Bo and others today seemed relatively calm.

"Fake it, let's see how long you can keep it up!" Simon chuckled inwardly. Now their biggest reliance, FEI Company, is on the same side as him. You will never buy their products again in this life!

As soon as he saw Taylor, Xu Bo's attitude changed. He directly challenged Taylor and asked: "Mr. Taylor, why did you return our deposit? This is a violation of the contract!"

"We haven't received the goods we ordered yet!"

When faced with Xu Bo's questioning, Taylor was still acting. He said, "It's such a pity."

"Mr. Xu, just now, Mr. Simon told me that this batch of goods cannot be shipped because it violates relevant laws and regulations. Therefore, in order to avoid causing losses to you, our company has refunded the deposit."

Xu Bo said angrily: "You have caused us huge losses, not only the deposit, but also various related project costs! According to the contract, you have to compensate us for the losses!"

"No, no, no!" Simon spoke, and he said with a smile: "Because this order violates the law, your contract is also invalid. We have made a judgment."

"According to regulations, FEI does not need to compensate you for any losses!"

If it were ten days ago, Xu Bo and others would have been so angry that they would vomit blood! They spent so much effort and effort, but the other party was completely unreasonable, did not follow the rules, and acted like a gangster, so that all their efforts were wasted!

Even FEI Company has changed its stance and defrauded customers regardless of its own company's reputation.

Shameless is an understatement for this kind of behavior!

Simon originally wanted to see the angry but helpless look of this group of Easterners, but he found that Xu Bo and others were not angry.

Xu Bo said: "We have been treated unfairly. We will not remain silent about this matter. The entire international community will know about it!"

Simon disagreed. It wasn't the first time they had done this. Could there be someone who would speak for them? Even if there is, they don't care, the Deng Kingdom is the boss of the world now!

Xu Bo's second sentence left Taylor and Simon confused.

"Also, I want to thank you today," he said.

"Thank us?" Simon and Taylor thought to themselves, are these Orientals so angry?

Xu Bo smiled and said: "Because just yesterday, I got the news that our country's research institute has developed an angstrom-level lens electron microscope. I originally wanted to return this batch of goods, but I was worried about breach of contract. Since you said The contract is invalid and the deposit is refunded, so for us, it’s really the best of both worlds!”

"You don't have to spend so much money to buy outdated equipment, and you don't have to bear the liability for breach of contract, so I have to say thank you!"
