Comrade, your ingredients are too complicated.

As representative products of the period of mass production, the four levels of equipment, Borg, Fletcher, Catshark and Liberty Ship, had an incredible production of 45, 175, 77 and 2751 ships respectively during the entire war.

The huge number and exquisite craftsmanship make them an indispensable combat force for the US Navy's Pacific and Atlantic fleets.

This is why Huang He dared to speak up. After all, only when the number is sufficient and the allies are fully staffed, will they consider signing the Lend-Lease Act.

If we ask for the extremely rare North Carolina and Essex right away, wouldn't Master Luo be so angry that he would jump up and down and yell that TG is taking advantage of the situation?

Rather than creating a lose-lose situation, it is better to ask for a sky-high price and let Achou pay back the money on the spot.

Anyway, it’s not the Fourth Master and the Eighth Master who are in a hurry, so just talk slowly.

After getting the answer he wanted and finishing the watermelon on the table, the Army reorganization expert stood up and prepared to leave.

Before leaving, he suddenly remembered that there was one thing he almost forgot to tell, so he quickly turned back and reminded Huang He:
"Oh, there is one more thing. Your junior's junior arrived in Shancheng with the representatives of the Ugly Country last night and is now staying at the guesthouse of the Eighth Office."

"If nothing unexpected happens, the comrades in the Air Force should be able to send him to the Weapons Experimental Research Bureau soon."

"The border region and the headquarters specifically asked me to remind you to do a good job of reception. It's not easy for them to come back from far away, so don't let them suffer any grievances."

As soon as these words were spoken, Huang He immediately began to think in his mind, trying to analyze the other party's exact identity.

But he soon gave up.

There was no other way. My junior had a very wide network of contacts. It was no exaggeration to say that if there were no special restrictions on nationality and other conditions, the names of people who met the criteria could even fill up an entire A4 paper.

"Huh? Who is it?"

"The Fifth Division didn't tell me in advance, so I had no idea about this."

Considering that Huang He had gone on a business trip to the headquarters some time ago and had just returned to the Weapons Testing and Research Bureau today, the Army Reorganization Expert simply gave up the idea of ​​joking.

"I only know his last name is Guo. You can ask for the details yourself."

"I'm leaving. See you in a few days. I'm waiting for your good news on the development of a new type of individual anti-tank rocket launcher."

"Okay, pay attention to safety on the road."

······
Two days later, Baotou Donghe Airport.

More than ten kilometers in the sky away from the Grassland Steel City, a passenger plane converted from an aerial train transport plane gradually lowered its altitude and flew slowly towards the military airport in the northwest.

In the cabin, a thin and elegant young man was reading a letter. His eyes were extremely complicated, as if he was reminiscing about some past events.

"Fellow student:
I received your letter and heard that you will be back soon. This is really happy news.

Now everyone is busy with mechanics. The work of the bureau is at the world's advanced level in terms of goals, content, and scientific research conditions in all aspects.

In a sense, this is a well-deserved paradise for scientists.

Come on! Come on!
I have prepared an office for you, a south-facing room on the second floor with a row of pines outside the window. Your residence is only a five-minute walk from your workplace, very close to me and my senior, so we can be considered neighbors.

I won’t write much more, we’ll talk in detail when we meet.

Sincerely
Welcome home!"

An unknown journey is often accompanied by unknown challenges.

But every time he finished reading the letters sent by his senior, a warm current would rise in the elegant young man's heart, helping him dispel all confusion and anxiety about the future.

"Senior! Director Huang! Wait for me, I'll be there soon!"

Just as the young man secretly made up his mind to have a big fight with his friends in the coming days, the plane had already arrived over Baotou Donghe Airport.

Recalling his superior's repeated instructions before departure, the captain decisively turned on the in-flight broadcast system and then gently reminded the only passenger on this flight:

"Mr. Guo, we are about to arrive at our destination. Don't forget what I told you before, and be sure to pay attention to safety."

Hearing this, the young man immediately withdrew his gaze from the letter. He adjusted his posture according to the previous training and made preparations before landing.

A few minutes later, the passenger plane landed steadily and began to taxi on the concrete runway.

Finally, the captain parked the plane right in front of the designated hangar according to the instructions of the tower staff.

"Hahaha! Junior, I finally saw you! It's been a long time since we last met, I missed you so much! As usual, you take my car, I'll take you around the city first, and then we'll go back to the bureau." "In order to welcome you, the cafeteria has specially prepared a table of Shandong cuisine."

"You've been eating General Tso's Chicken for so long, today I'm helping you reminisce about the taste of your hometown, you're in for a treat."

As soon as he walked down the escalator of the plane, the elegant young man heard a familiar laugh. Looking in the direction of the sound, he saw a handsome intellectual holding the car door with one hand, looking at him with a smile on his face.

Seeing his two junior classmates standing there in a daze, Xuewen Ru Lin walked up to them and hugged them by the neck.

"After such a long time, your reaction is still as slow as ever. We have limited time, so let's get in the car and leave, and don't keep the comrades in the bureau waiting too long."

"By the way, do you have any large luggage? My security team can help you with it."

The sudden physical contact brought Master Guo back to his senses.

I was in a daze because I never expected that my hometown would take me so seriously. For just a simple airport pick-up job, the border area had arranged more than a dozen soldiers to be responsible for security.

But, I am just a student who hasn’t even graduated with a Ph.D., is it necessary to make such a big fuss?

Temporarily suppressing his confusion, he looked around and said to the waiting senior:
"Apart from the necessary materials and books, my luggage only contains a few spare clothes and daily necessities. Don't bother."

Before he could finish his words, Xuewen Rusenlin waved his hand, and two nimble soldiers trotted towards the passenger plane and carried out several suitcases.

While his junior was still not able to react, he pulled him to the back seat of the Beetle, and then signaled the driver to drive to Baosteel.

After a series of smooth operations, Master Guo entered the main road of the city in a daze.

"How do you feel about coming to Baotou for the first time? You may not believe it, but it only took more than half a year to build this city from scratch."

"During my time in Suiyuan, I was inspired by the bright prospects every day, and I believe you will have the same experience in the future."

Perhaps it was because when he was studying in Chouguo, he was often driven around the city by his seniors. Master Guo, who was a little nervous at first, was much calmer after getting in the car.

Looking out the window at the bustling, heavy-industrial street scene, and the trucks passing by from time to time, he said with emotion:

"Baotou is really an incredible city. Every resident here is full of vitality, which is something I could not have imagined a few years ago."

"My previous premonition turned out to be correct. My career, destiny and achievements must be in Suiyuan!"

······
Two hours later, the two ended their trip to Baotou and took a car to the Weapons Testing and Research Bureau together.

When he walked through the gate and passed by the laboratory building of his department, he stopped moving forward like a forest and proudly introduced it to the junior student beside him:
"The building in front of you is the Mechanics Center of the Bureau. It is also where we will work together in the future."

"Almost all the top scientists in the country are gathered here. If a university is established based on this, the comrades in the building can even form a reference square."

"Since I came back, Caltech can only rank second in my heart!"

The pride from the senior student made Master Guo look forward to his future work and life. At his urging, the two continued to move forward, walking fast all the way to the director's office.

After arriving at the destination, knowledge came out directly from the door like a forest. Unfortunately, Huang He was not in the room at this time because of work.

Seeing this, he picked up the phone on the table and said to his junior:

"Please take a seat. I'll call the director back. Just take any document you want from the bookshelf or the desk. Don't hesitate."

With the approval of his senior, Master Guo casually picked up a folder from the table and prepared to kill time before the real owner came back.

But just by taking a look at the title of the book, surprise and unexpectedness surged into his heart.

"Ah! Transonic flow discontinuity solution? Isn't this the topic I've been researching recently? It turns out Director Huang has also made some achievements in the field of sound barrier. He is really a kindred spirit!"

When these words were spoken, knowledge was like a forest that smiled knowingly.

As early as when he first met Huang He in college, he felt like he had met a soulmate. Even after many years, when they completed their studies in different countries, this feeling remained unchanged.

This is probably the hexagonal warrior, which is everywhere in various fields of mechanics.

Just as the knowledge was lost in the memory like a forest, Master Guo had already opened the folder. Then, in the reference column, a very impressive opening statement came into view.

"This article does not need to refer to any literature. The relevant theories about the power system in this article can be found in general aerodynamics textbooks. The "hypersonic similarity" is also proposed for the first time in this article." (End of this chapter)
