Xueba: I study hard in the wasteland world

The official background is always more powerful than the solitary survivors. As expected, Su Yu got the book he wanted in this "offshore market".

Of course, salt is very valuable, and in exchange for that truck of salt, there is a pickup truck full of arms.

As for the book Su Yu wanted, it was given as a gift.

More importantly, during this trip, "Dingming Base" and "Offshore Market" established a relatively stable trade route: "Dingming Base" can use salt to trade with the officials of "Offshore Market".

And salt is not worth mentioning to "Dawn Base".

Su Yu brought drilling equipment. She originally wanted to dig a well to get water, but unexpectedly a "salt well" was dug, and they started making salt.

This "Dawn Base" with only 23 people can be regarded as having some resources of its own.

Salt was exchanged for arms, and the arsenal of "Dawn Base" became abundant. The soldiers' live-fire training also became intensive every day.

However, the "pop, pop, pop, pop" sound of gunfire annoyed Su Yu, so the live-fire training turned into "battlefield combat": every day, soldiers in teams of three drove into deserted cities to scavenge and fight!

And having soldiers means domination and exploitation.

When "Dawn Base" soldiers enter the city for actual combat, they always bring back a few scavengers. Although there are still 23 people in the base, there are already dozens of tattered slaves outside the base.

…

"slave?"

Su Yu looked a little confused at the dirty girl in front of her.

After all, this is not his own world, so in fact, Su Yu is not too concerned about the development of the "Dawn Base" in the wasteland world. He is more concerned about his own study.

So after a long time, Su Yu realized that there was a group of slaves outside the "Lingming Base": some were drying salt in the salt factory, some were farming in the fields, and some were specialized in carrying water from the distant river.

"Don't we have water pumps? Why do we need someone to fetch water?"

Seeing the dark-skinned men shirtless, carrying water, and struggling up the mountain step by step, Su Yu was a little confused.

"Because if they don't carry water, they won't have work to do, and if they don't have work to do, they won't have food to eat." Song Qing, who was standing behind Su Yu, explained.

Su Yu shrugged. It was clear that tools could be used to produce more efficiently and free up manpower, but in this slavery, if one wanted to eat, one had to depend on the slave owner.

Although Su Yu is a science student, he has also studied history and knows that feudalism is more advanced than slavery.

Su Yu was thinking: The unified social system in this wasteland world is slavery, so if I implement feudalism first, will I be able to unify the world?

So, Su Yu told Song Qing: "Starting from tomorrow, free all slaves!"

Su Yu then spoke: "Give them loans, lend them tools, let them cultivate it themselves, and tell them that the harvest from the cultivated land will be 30% to 70%!"

"Ah!" Song Qing was a little anxious: "Only giving them three shares of the harvest is too little!"

Su Yu was speechless and said to Song Qing: "We charge three shares of the rent! Give them 70%!"

With that said, Su Yu waved her hand and went back to the room to continue reading.

Finally, just like in a fantasy novel, the male protagonist went to the "secret realm" to practice. Su Yu, who had read dozens of books, came back from the wasteland world with "heavy internal strength".

Although real time is suspended, Su Yu is still the same Su Yu as before. But at this moment, Su Yu's mind was filled with knowledge.

Xijing Ruixing Business Data Co., Ltd. conference room.

The person standing in the main position is not the boss of this company, nor the department manager of this company, but the "part-time employee" of this company - Su Yu.

Su Yu, who was sitting in the main seat, said: "Starting today, our project will have a new idea."

"Su Yan, we are already halfway through our mission. Now you want to improve an idea, isn't it bad?"

The person who questioned Su Yu was Yao Guolong, the new team leader of the "Drawing Group".

Su Yu did not rush to refute, but just picked up the drawing and took a look at it.

Those drawings that were considered exquisite and satisfactory in his eyes have now become shoddy in his eyes.

"Xijing Ruixing Commercial Data Co., Ltd." is only deriving foreign fighter jets based on Su Yu's derivation model.

There is no real reference. They are not optimizing the fighter plane, let alone designing a new fighter plane.

However, after reading dozens of books in the wasteland world, especially learning some knowledge about advanced fighter aircraft in the wasteland world, Su Yu had a completely new understanding of his derivation ideas.

The "main business object" of Su Yu's "company": the United States and China's B2 stealth strategic bomber.

This is the most advanced aircraft in the world today, like an alien black technology.

Its existence may not be about who is fighting whom, but more of a strategic threat. If it goes out and flies around, it can solve many things.

It is very advanced, but Su Yu has read many related books and materials in the wasteland world, and he has richer and more advanced aircraft knowledge in his mind.

Su Yu is not yet capable of designing a fighter plane. After all, the design of this fighter plane is not only about the optimal aerodynamic layout on the drawings, but also involves materials science, industrial level, and a series of other aspects.

However, although Su Yu does not have the ability to design a fighter aircraft, through deepening his understanding of fighter aircraft, what Su Yu can do is to better deduce the B2 through his own theoretical model.

Su Yu didn't care about everyone's doubts, and said: "The project is suspended for one week. Let's take the time to rest. When I come back next Saturday, I will bring a new model theory."

"Is it reliable?"

In the conference room, Yao Guolong, the new leader of the "Drawing Group", was discussing with a distrustful tone.

"Anyway, I think he is more reliable than you." Xu Wei, leader of the model framework architecture analysis team, said calmly.

This project has been running at high intensity for several months, and Xu Wei thought it was great to take a week off.

Although Su Yu had ideas in his mind, it still took a lot of effort from Su Yu to output the ideas in his mind and organize them into a report that others could understand.

Some knowledge systems in the wasteland world are different from those in the real world, but the basic principles are still the same.

What Su Yu needs to do is combine the knowledge of the two worlds, optimize his ideas, and thereby optimize the ideas of the entire "company". In this way, he can lead the entire team to complete the derivation of the B2 stealth strategic bomber better and more appropriately.

The sun shines through the glass and onto the desk in the library. Su Yu spreads out the draft paper and writes on the blank scrap paper:

Inviscid flux Viscous flux (2)ρuαt+xβ(ρuαuβ+pδαβ

Inviscid fluxταβviscous flux)=0

From d/dt≡t+uββ, INSE can be rewritten as (3)ρmu˙a→=p+

…

This line of calculation written by Su Yu is the famous "NS equation", one of the seven major mathematical problems in the world.

For decades, countless mathematicians and physicists have been challenging this problem and have verified it countless times, but have achieved nothing.

But this does not affect the promotion of the development of human science and technology by the "NS equation" at all.

Of course, Su Yu didn't want to challenge it, but wanted to use this equation as the core to conduct new model analysis.

Picking up the pen, Su Yu began to make deductions and calculations.

This "NS equation" is very long, and what is needed most is concentration. The long mathematical symbols are drawn in Su Yu's pen like characters from a heavenly book.
