In the following days, Lu Jiadong and Guo Rui's correspondence became more frequent, basically a few days apart, there would be several letters shuttling back and forth in a space thousands of kilometers apart, as for the content, although it has been detached from the beginning of the youth and boring, but in general it is still discussing the current military technology.

It's just that compared with the initial aviation theoretical knowledge, now the two are talking more about the future development direction of weapons and equipment in the letter, Lu Jiadong put down the concerns in his heart, and then looked at the correspondence between him and Guo Rui with a relaxed and indifferent attitude, so he described a lot of ideological systems and knowledge structures that had not been told before.

As for Guo Rui, naturally in the exchange between the two, the party that benefited the most, in addition to the mastery of relevant technical knowledge, more and more relaxed words, in-depth explanations and vivid and interesting metaphors, all made Guo Rui, a talented, but delicate beautiful girl, perceive some unknown feelings, maybe even Lu Jiadong, one of the parties involved, may not be able to perceive it, but still let Guo Rui faintly capture, which makes the girl feel happy and a little sad.

But no matter what, under the frequent correspondence between the two, the originally strange and distant distance was quickly shortened unconsciously, even Lu Jiadong, who had a little big nerves, began to sigh when he made great progress in his hard pen calligraphy, and wrote letters with a little girl with good handwriting, there are still some benefits, at least I can practice the words that have been taken out of my hand. In order to be more confident when signing in the future.

On the second day of a certain day, Guo Rui, who had just returned from outside. I found someone's letter in the communication room of the military compound, and looked at the handwriting on the envelope that had gradually become neat, and a sweet smile suddenly appeared on the pretty face that was originally like a winter, just like a warm breeze blowing across the surface of a lake with thick ice, and the ice and snow melted in an instant, revealing a pure and beautiful lake. This made the master of the communication room, who was familiar with her, very curious, and couldn't help but ask slowly with a gentle smile:

"When I was taking the exam, I didn't see you so happy. Who the hell is this Lu Jiadong?"

"A friend!"

Guo Rui was stunned for a moment, and then said these four words very quickly, but the voice had not yet fallen, and he did not wait for the gossip conveyor room master to continue to ask. He hurried out. I only saw that the master of the communication room shook his head meaningfully, and Guo Rui, who was walking in the wind, also had crimson cheeks.

It wasn't until I returned home and locked up in the bedroom that the scarlet for no reason receded a little, until this time. She calmed down, thinking. What's wrong with you? The mention of someone's name makes you blush for no reason? It's a bit annoying.

Although he felt sorry for himself in his heart, he did not have any anger and vain, but looked at the letter in his hand, and the sweet smile at the corner of his mouth became even sweeter and brighter, so he quickly threw the document bag in his hand on the bed, and sat in front of the desk, quickly opened the yellowish envelope, took out the neatly folded letter paper, carefully spread it in his hand, his long eyelashes flickered, and the water-like eyes reflected the words on the letterhead, and read it carefully.

The content of the letter is to answer questions and solve doubts in the previous letter, mainly around the future development of weapons and equipment thinking and prospects, especially the elaboration of modular equipment, so that Guo Rui's eyes can't help but light up, this new weapon and equipment development ideas, she was in school, listened to the teacher explained,

It's just that this kind of thinking has just emerged in the West, so the teacher is only a certain idea for future development, and it is very simple, but now, Lu Jiadong has said this new set of ideas in the letter, which is both simple and easy to understand, and extraordinary:

"According to what I said before, in my opinion, the development trend of weapons and equipment in the future is modularization, to put it bluntly, it is to turn weapons and equipment into something similar to a platform, to use a simple analogy, just like a beautiful big girl wearing clothes, a beautiful face and a slender figure are the platform, and clothes are the corresponding functional accessories, wearing blue overalls, it proves that she is a worker, wearing a white coat, she is a doctor in the hospital, wearing a beautiful flower skirt, she is a lively girl who is in love, if she wears pajamas, it means that she is to rest”

Seeing this, Guo Rui's face turned slightly red, and she thought to herself, what example is this guy giving is not good, he has to lift the eldest girl to wear clothes, in fact, Lu Jiadong originally wanted to use building blocks as a metaphor, but when they were born, it would be good to be able to eat well, how could there be any building blocks.

So after thinking about it, I found such an "easy to understand" metaphor, if you know that this can also make a certain girl blush and heartbeat, it is estimated that Lu Jiadong, who is thousands of miles away, will definitely scream all the time, because he has controlled the scale to the most harmless range for humans and animals, if it is according to the original idea, it can be treated as a "forbidden ~~ book".

However, Guo Rui didn't know Lu Jiadong's original thoughts, and she didn't want to know, because the current scale still reached the limit in her heart, and the unexplained crimson made her smiling face more pretty.

"Bad guys!"

After speaking, he raised his eyebrows and continued to look down:

"The equipment is the same, the same platform, wearing different 'clothes', can play different effects, in this regard, the Americans do the best, take the torpedoes commonly equipped by the Navy as an example, the same superpower Soviet Union, in the torpedo model can be described as a vast star, mouth shapes are even more diverse, from 324mm to 680mm, can be said to have everything, as for the use is more diverse, and is still developing new torpedoes.

However, as the world's largest naval power, the United States has nothing more than two types of torpedoes, one is the 324mm ship anti-submarine torpedo MK46, and the other is the 533mm heavy torpedo MK48 for submarines; although it looks very monotonous, its performance is the world's leading, and the fundamental reason for this is that the United States uses modular technology and ideas to constantly change different 'clothing' for them according to their development and operational needs, just like a big girl wearing clothes.

As for the cost-effectiveness ratio, it is not to mention, changing clothes is easier and faster than amputation, so this method seems conservative, but it is a very potential development idea, so I think the future development of weapons and equipment should move closer to this aspect."

Looking at the letter in her hand, Guo Rui couldn't help nodding silently, although she may not understand the deeper truth, but the girl does understand when she wears clothes, because she is a beautiful girl who loves beauty, and naturally knows what different outfits mean to girls.

Or many with a flower, or change a beautiful really good shirt, the state of the whole person will change, and by extension, if this method is applied to weapons and equipment, it may be difficult to develop in the early stage, but in the future upgrading, it is extremely convenient and easy, and more importantly, in this way, as long as the "clothes fit", then the relevant weapons and equipment will never be outdated.

After all, Guo Rui is also a top student of a key university in Beijing, and after graduation, she studied under Yang Hongyi, and she is an extremely intelligent woman, so after reading Lu Jiadong's letter, she quickly realized the great value contained in it, since she figured it out, she no longer blushed and heartbeat on the metaphor of the beautiful big girl, but felt that the person who could write these words must be a wise man with great wisdom, so his eyes drooped slightly, thinking about his wisdom and ability, and the crimson that had just receded slowly climbed up again

But at this moment, a dull sound of closing the door completely broke Guo Rui's growing girlish heart, she knew that this was her father Guo Qingshan back, so she put away the letter on the desk and returned to her usual appearance, then she stood up, opened the door, looked at Guo Qingshan who was hanging up her coat, and shouted:

"Dad, why did you come back so early today?"

"I came back early because I had a meeting in the evening, so I had to eat early to prepare my strength!"

"It's not a marathon, you need to prepare in advance? Besides, doesn't Jingxi Hotel have a restaurant?"

"Jingxi Hotel has a restaurant, but can you eat at ease?" Speaking of this long-distance running term that had just been circulated in China, Guo Qingshan shook his head helplessly, and immediately laughed at himself:

"It's really a 'marathon', it's been almost a month, and I haven't come up with a reason yet, alas, I don't know how long I have to run!"

Guo Qingshan sighed, of course, is the new rocket artillery project, because the funds are limited, can only choose one investment, so between the long-range rocket and the suppression rocket artillery, the second artillery and the army are deadlocked, in the blink of an eye for almost a month, endless discussions and disputes every day,

Guo Qingshan, the head of the General Staff Armament Department, can be said to be physically and mentally exhausted, and in the face of the latest, but clichéd seminar that is about to usher in the evening, Guo Qingshan has to go home early to eat and recuperate, so that he can stay up longer at night.

Guo Rui put her hands in her pants pockets, leaned on the corner of the sofa, looked at Guo Qingshan's tired and emaciated face, and felt distressed for no reason, although after the death of her mother, she became a little cold, even in the face of her father Guo Qingshan,

But no matter what, a father is a father, and her haggard face was reflected in her beautiful pupils, which made her feel distressed, and her reddish lips suddenly pursed into a thin red line (to be continued. )
