The God of Wealth starts with doing whatever you want

The atmosphere in the conference room became somewhat subtle after Xu Yun took his seat.

Zhao Weiguo spoke first, his voice steady and powerful.

"Comrade Xu Yun, let me introduce myself first."

These three are all top experts in our aviation industry and core members of this stealth fighter technology verification team.

He pointed to the first elderly man on the left, with gray hair and thick glasses.

"This is Academician Chen Wenyuan, chief aerodynamics expert of AVIC, and one of the main designers of the J-20's aerodynamic layout."

Academician Chen nodded slightly to Xu Yun, his gaze behind his glasses scrutinizing her.

Zhao Weiguo then introduced the second person, an elderly man with a thin face and long, slender fingers.

"This is Academician Wang Zhenguo, an expert in aerospace materials and structures, who has led the research and development and application of various new composite materials."

Academician Wang did not speak, but instead looked at Xu Yun with his eyes that seemed to be able to see through the microscopic structure of the material.

"this……"

Zhao Weiguo pointed to the elderly man on the right who looked the youngest but was actually over sixty years old, and said, "This is Academician Li Weimin, an expert in avionics and stealth technology, and the chief designer of my country's first airborne active phased array radar system."

Academician Li gave Xu Yun a professional smile, but his eyes also held a look of inquiry.

Xu Yun stood up and bowed slightly to the three academicians.

"Academician Chen, Academician Wang, Academician Li, I have long admired your names. It is my honor to meet the three of you today."

His attitude was neither humble nor arrogant, showing neither the stage fright of a young person nor the affected arrogance, which softened the gazes of the three academicians somewhat.

Zhao Weiguo gestured for Xu Yun to sit down and got straight to the point.

"The three academicians have conducted a three-month verification and simulation of the technical data you provided."

I've invited you here today for two reasons: first, to formally confirm the feasibility of these technologies; and second, to hopefully answer some questions encountered during the verification process.

Academician Chen Wenyuan spoke first.

His voice was slightly hoarse, but he spoke clearly, saying, "Mr. Xu, please forgive my bluntness."

The aerodynamic layout design you provided uses a 'vortex control' theory that we have never disclosed before.

I proposed this theory in an internal research report three years ago, but it was known to only a very small number of people.

He paused, adjusted his glasses, and said, "I'd like to know how you obtained this theory and performed such ingenious calculations based on it?"

The moment the question was raised, the atmosphere in the meeting room became tense.

This is not just a technical inquiry, but also a probe to find out the true origin of these technologies.

Xu Yun remained calm as he took out a tablet computer from his briefcase, swiped his fingers across the screen a few times, and brought up a series of complex fluid dynamics formulas and three-dimensional models.

"The report that Academician Chen mentioned should be numbered 'CFD-2019-073', and its title is 'A Preliminary Exploration of Fighter Maneuverability Optimization Based on Unsteady Vortex Dynamics'."

Xu Yun replied calmly with a smile, "On page 17, you put forward a key hypothesis: by using micro-adjustment flaps on the leading edge of the wing, the generation location and intensity of the separation vortex can be actively controlled, thereby maintaining lift at high angles of attack."

Chen Wenyuan's eyes widened suddenly.

That report was highly confidential and had never been made public. Even the report number was only known to the core personnel involved in the project.

Xu Yun continued, "Your assumptions are completely correct, but there is a calculation error in the control of eddy current stability."

Please look here…

He turned the tablet toward Academician Chen, where a set of complex partial differential equations were displayed.

"The simplified model of the Navier-Stokes equations you used neglects the influence of boundary layer transition on the vortex core structure."

In actual flight, when the angle of attack exceeds 35 degrees, this neglect will cause the calculated results to deviate from reality by approximately 12%.

Xu Yun ran his finger across the equation and said, "I made a modification based on this, introducing the SST k-ω method from the turbulence model, and combined it with large eddy simulation to predict the spatiotemporal evolution of the separated eddies."

The revised model shows that all you need to do is add a high-frequency, low-amplitude oscillation mechanism to your designed micro-flap.

He brought up a 3D animation showcasing an extremely sophisticated mechanical structure on the leading edge of the wing.

"If the oscillation is performed at a frequency of 200 times per second with an amplitude of no more than 0.5 millimeters, intervention can be made before the separation vortex becomes unstable, increasing the controllable angle of attack from 42 degrees to 58 degrees."

There was silence in the conference room.

Academician Chen Wenyuan stared intently at the screen, his lips trembling slightly.

After a full ten seconds, he slowly raised his head, his voice filled with barely concealed excitement, and asked, "This oscillation mechanism... how did you come up with it? How were the frequency and amplitude data determined?"

"Through biomimetic research on bird wings."

Xu Yun calmly replied, "When a swift dives and turns at high speed, the leading edge of its wings will produce a similar slight vibration. This instinct, which has evolved in biology, has precisely solved a century-old problem in aerodynamics."

He paused, then added, "Of course, a lot of computation is still needed to go from biological mechanisms to engineering implementation."

I developed a specialized artificial intelligence algorithm that simulated over 80 million combinations of vibration parameters, ultimately selecting the optimal solution.

Academician Wang Zhenguo suddenly spoke up.

His question was more pointed: "Then what about the materials? The kind of 'high-frequency micro-oscillation flap' you designed requires the materials to undergo micro-motion at a frequency of 200 times per second while bearing huge aerodynamic loads."

Existing titanium alloys or composite materials, under such high-frequency cyclic loading, will not have a fatigue life exceeding 500 hours.

"This is the second question I want to ask Academician Wang."

Xu Yun switched screens to display a new material microstructure diagram, saying, "I call it 'gradient nanocrystalline composite metal matrix material'."

Wang Zhenguo suddenly stood up from his seat, almost lunging at the screen.

That was the direction he had been researching in the field of materials science for twenty years, but he was always stuck in the laboratory stage and could not achieve industrial-scale preparation.

"The structural design of this material..."

Wang Zhenguo's voice trembled slightly as he excitedly asked, "How did you achieve the gradient distribution of nanocrystals in the matrix? And these..."

He pointed to the peculiar interface structures in the picture.

How do these heterogeneous interfaces exist stably?

Xu Yun patiently explained: "Traditional equiaxed nanocrystalline materials do indeed have problems such as poor plasticity and low thermal stability."

My solution is to abandon the uniform structure and instead design a gradient.

From the surface to the core, the grain size gradually transitions from 10 nanometers to 500 micrometers.

He pulled up the manufacturing process flow chart and said, "The manufacturing method uses my improved 'asynchronous rolling + cyclic annealing' process."

The key lies in controlling the deformation and temperature gradient in each pass of the rolling process, while simultaneously introducing a high-frequency electromagnetic field during the annealing stage to induce grain boundary migration and recrystallization.

What about the interface issue?

Wang Zhenguo pressed further: "The interface between heterogeneous materials is the origin of fatigue cracks!"

"Generate a transition layer in situ..."

Xu Yun zoomed in on the image at the material interface and replied with a smile, "During the preparation of the composite material, I added trace amounts of rare earth elements."

At high temperatures, they migrate to the interface and react with the matrix elements to form an amorphous transition layer with a thickness of only 2-3 nanometers.

This transition layer effectively alleviates stress concentration and inhibits crack initiation.

Wang Zhenguo slowly sat back in his chair, took a deep breath, and turned to Zhao Weiguo.

"Sir, if the process parameters provided by Mr. Xu are feasible... then the fatigue life of this material is at least five times that of existing aerospace materials."

Not only can it be used on the flaps, but the entire aircraft structure can benefit from it.

Academician Li Weimin then spoke up, his question directly addressing the core of stealth technology.

"Mr. Xu, regarding your proposed 'adaptive plasma stealth coating,' I have tried to reproduce it in the laboratory, but I have been unable to solve two problems."

First, the real-time matching of plasma density and frequency; second, the impact of the plasma layer on the performance of the airborne radar itself.

Xu Yun nodded and smiled, "Academician Li has hit the nail on the head. The difficulty of adaptive stealth does indeed lie in the word 'adaptive'."

He pulled up a set of extremely complex electromagnetic calculation models.

"Traditional plasma stealth is static, involving covering the surface of the aircraft with a layer of plasma to absorb radar waves of a specific frequency band."

However, modern radar has advanced to the stage of multi-band, variable-frequency scanning, rendering static stealth ineffective very quickly.

"My plan is dynamic..."

Xu Yun demonstrated an ingenious sensor network layout, saying, "More than 100,000 miniature electromagnetic sensors are deployed on the surface of the aircraft to monitor the frequency, power, and incident angle of the incident radar waves in real time."

This data is transmitted to the onboard supercomputing system, which calculates the optimal response strategy within 0.01 seconds and then controls the discharge parameters of the plasma generation unit.

Li Weimin frowned and said, "0.01 seconds? This response time means that ultra-high-speed data processing and command issuance are required."

However, existing airborne computers cannot do this.

"Therefore, we need a completely new computing architecture."

Xu Yun pulled up a chip design diagram and replied, "This is my 'neuromymmetric processing chip,' which mimics the neural network structure of the human brain and is specifically designed to handle this kind of high-dimensional, nonlinear real-time optimization problem."

A single chip has fifty times the computing power of a traditional airborne computer, while consuming only one-third of its power.

"But the plasma layer will affect the performance of our own radar."

Li Weimin pointed out the key issue and questioned him.

"When the aircraft is engulfed in plasma, our radar waves cannot be emitted."

Xu Yun laughed and said, "So the plasma layer is not a full coverage, but a 'smart skin'."

Next, he presented a stunning design.

The surface of the machine is divided into millions of tiny hexagonal units, each of which can be controlled independently to generate plasma when needed and remain transparent when not needed.

"When our radar needs to operate, the plasma units in the corresponding area will be temporarily shut down, forming an 'electromagnetic window'."

The position and size of this window can be dynamically adjusted to match the radar's scanning mode.

Xu Yun explained, "When enemy radar waves enter from other directions, plasma will be generated in the corresponding area to absorb them."

"..."

The three academicians fell into a long silence.

They exchanged glances, both seeing the same shock in each other's eyes.

Each of these technological ideas is revolutionary.

Each of these solutions is ingenious.

What's even more frightening is that Xu Yun has perfectly integrated these technologies from different fields into an organic whole.

Aerodynamics, materials, electronics, and stealth—they support and reinforce each other. Academician Chen Wenyuan finally spoke, but his tone had completely changed, shifting from initial scrutiny to sincere inquiry.

"Mr. Xu, there's still something I don't understand about that eddy current control mechanism."

High-frequency micro-amplitude oscillations can indeed stabilize vortex separation, but how can we ensure that the oscillation mechanism itself does not flutter in high-speed airflow?
These micrometer-scale precision machines are extremely sensitive to vibration environments.

Upon hearing this, Xu Yun replied earnestly, "Academician Chen has considered everything very thoroughly."

I designed an 'active vibration suppression system' that embeds piezoelectric sensors and actuators inside the oscillation mechanism to monitor and counteract external vibration interference in real time.

At the same time, the device is manufactured using the gradient nanocrystalline material I just mentioned, whose high damping properties can effectively absorb vibrational energy.

Wang Zhenguo then asked, "So, regarding the material preparation process, what are the specific high-frequency electromagnetic field parameters you mentioned?"
Key data such as magnetic field strength, frequency, and duration of action…

"This is a detailed process parameter table."

Xu Yun pulled up an encrypted file and said, "It includes the gradient settings for electromagnetic field strength from 0.5 to 3 Tesla, the frequency sweep strategy between 100kHz and 10MHz, and the time-temperature curves for each annealing stage."

Li Weimin also joined the questioning team.

"What about the manufacturing process for neuromorphic chips? This new architecture requires a specialized manufacturing process that existing semiconductor production lines cannot produce directly."

“I redesigned the manufacturing process to make it compatible with existing 7-nanometer processes.”

Xu Yun continued to demonstrate the process flow diagram, replying, "With just a few minor adjustments to the photolithography and deposition processes, we can achieve mass production on the existing production line."

This is the adjustment plan and a list of the required equipment.

The meeting lasted from 10 a.m. to 3 p.m.

The staff brought a simple lunch, but the five attendees barely touched their food.

The three academicians asked one question after another, from technical principles to engineering implementation, from theoretical calculations to experimental data, demanding an in-depth understanding of every detail.

Xu Yun remained calm and composed throughout.

No matter how tricky the question, or how specialized the field, his knowledge is unfathomable.

What's even more remarkable is that he can not only answer "what" but also explain "why" and even predict "what problems might be encountered and how to solve them".

At four o'clock in the afternoon, as the sun began to set, Academician Chen Wenyuan finished asking his last question about transonic aeroelastic coupling.

Xu Yun proposed a clever decoupling control scheme.

Silence fell over the meeting room once again.

This silence was completely different from the scrutiny and probing that had occurred that morning.

This is a silence born of profound admiration, a respect for fellow travelers encountered at the pinnacle of knowledge.

Finally, Academician Chen Wenyuan slowly stood up.

This highly respected elder in the aviation industry bowed deeply to Xu Yun.

"Mr. Xu, please accept my respect."

His voice choked with emotion as he said, "I've spent my whole life working on aerodynamics, and I thought I was at the forefront of this field."

Only today did I realize what true genius is, and what a true breakthrough is.

Academician Wang Zhenguo also stood up.

"I have been studying materials for forty years, and I always thought that gradient structures were a distant dream."

Today you have not only achieved it, but also provided a complete industrialization path.

This achievement deserves to be remembered by all materials scientists.

Academician Li Weimin was the last to stand up.

His eyes gleamed as he said, “Adaptive stealth, intelligent skinning, neuromorphic computing… We’ve discussed these concepts countless times, but they’ve always remained on paper.”

You not only brought them to life, but integrated them so perfectly.

Mr. Xu, you single-handedly advanced the technological level of Chinese fighter jets by at least twenty years.

Zhao Weiguo watched this scene quietly, a gratified smile on his face.

He had long known that Xu Yun was extraordinary, but he never expected him to be this extraordinary.

Academician Chen Wenyuan suddenly said solemnly, "Mr. Xu, on my personal behalf and on behalf of AVIC, I formally invite you to join our stealth fighter project team."

We hope you can serve as the chief engineer for this project and lead the team to turn these theories into reality.

Academician Wang Zhenguo immediately echoed this sentiment.

"On behalf of the Institute of Aeronautical Materials, I extend an invitation: you are the only candidate for chief engineer."

Only you can truly understand the essence of these technologies and coordinate the various subsystems to achieve optimal integration.

Academician Li Weimin was even more direct.

"Mr. Xu, as long as you are willing to come, all the resources of the project team can be allocated to you."

Personnel, equipment, and funding will all be prioritized; we need you to join us.

The three academicians' gazes were fervent and sincere.

They knew all too well the value of this young man.

This is not just a genius; this is a person who can change the fate of a nation's aviation industry.

However, under the expectant gazes of the three, Xu Yun slowly shook his head.

"Thank you for your kindness, three academicians."

He said in a calm but firm voice, "But I cannot accept the position of chief engineer."

The temperature in the conference room seemed to drop several degrees instantly.

Academician Chen Wenyuan was anxious.

"Why? Is it a matter of compensation? We can apply for special policies from above! Is it a matter of authority? The chief engineer has the highest technical decision-making power within the project! You can make any demands you have!"

"It's neither a treatment nor an authority."

Xu Yun explained softly, "It's because I can't stay in a particular project team for long."

He looked at the three academicians and said sincerely, "I have many other things to do."

Some technologies need further improvement, some new directions need to be explored, and some... I'm quite lazy, I like freedom, and I also want to spend most of my time with my family.

He thought of Zhong Yanyan and Xinuo in the hospital, his three newborn children at home, and his close female friends.

"but……"

Xu Yun changed the subject and said with a smile, "I promise to participate in this project as a special advisor."

I am always ready to provide support for all technical details and any difficult issues.

If needed, I can also visit the project team regularly for on-site guidance.

He brought up the calendar on his tablet.

"We can establish a fixed communication mechanism, with at least one technical seminar per week and one on-site work session per month."

If you have any questions, you can contact me at any time through encrypted channels.

"..."

The three academicians looked at each other, their eyes showing regret, but also understanding.

Such a person cannot be confined to a single project.

Academician Chen Wenyuan sighed and finally nodded.

"Okay, a special advisor is fine too, but you have to promise that you'll be available whenever I call."

"I promise."

Xu Yun solemnly promised: "Although I love freedom, I also love my country!"

After thinking it over, Academician Wang Zhenguo proposed a compromise.

"How about this, Mr. Xu will serve as the chief technical advisor and have veto power over technical decisions."

The three of us old guys are in charge of the day-to-day management, but when it comes to major technical issues, you have to make the final decision.

"This arrangement is acceptable."

Zhao Weiguo, who was standing to the side, finally spoke up: "I will report to my superiors and give Comrade Xu Yun a formal letter of appointment."

Compensation will be based on the highest level of technical expert standards, and in terms of authority…

He looked at Xu Yun and said, "I'll give you access to the highest level of classified information channel, so you can access all project materials at any time."

Xu Yun nodded: "Thank you, leaders, thank you, three academicians. I will do my best."

The meeting ended at 6 p.m.

The three academicians reluctantly saw Xu Yun off at the entrance of the guesthouse, still discussing technical details.

"Mr. Xu, I'd like to focus on discussing that turbulence model at next week's seminar..."

"The first batch of samples for the material preparation should be ready next month. You must come and see them then..."

"The chip tape-out has been arranged, and samples are expected to be available in two months..."

Xu Yun agreed to all of them and shook hands with the three academicians to say goodbye.

By the time I got into the car, it was already completely dark.

As Li Mu drove out of Xishan, he glanced at Xu Yun, who was resting with his eyes closed, in the rearview mirror and couldn't help but exclaim, "Mr. Xu, today the three academicians are completely impressed by you."

I've been with them for three months, and I've never seen them treat anyone with such respect.

Xu Yun opened his eyes, looked at the night view of the capital city passing by outside the window, and said with a soft laugh, "They are the true national heroes. I am merely standing on the shoulders of giants."

"You are too modest."

Li Mu shook his head and said, "Those people are all arrogant and haughty. You are the first person who can win their hearts and minds."

"Haha."

Xu Yun couldn't help but laugh and said, "Then I guess I really am pretty awesome."

However, only he himself knew the technical details of this skill; he was merely using someone else's knowledge to his advantage, and everything came from his own system.

On the surface, it's a super-rich system, but now Xu Yun feels that besides financial wealth, it has also brought him a wealth of knowledge! (End of Chapter)
