"Haha, it's finally done!" Mark the last number of the main design of the propeller fan blade and sign your signature in the most inconspicuous position in the lower right corner of the drawing, which means that today's work is finally completed.

Chen Xu put his sore back on the back of the chair, stretched a big waist, looked at the dark world outside the window, glanced at the alarm clock on the table, and pointed the pointer at one o'clock.

When I was working, time passed the fastest, and I was engrossed in copying pictures, and before I knew it, it was already late at night.

Yawning out of the room, the living room was still lit, and the eldest brother was sitting on the sofa leaning forward with black-rimmed glasses. Holding two pieces of A4 paper in his hand, his eyes stared at the text on it and frowned, not knowing what he was thinking, Chen Xu didn't notice it at all, and there were more than a dozen similar texts on the coffee table.

"Find time to change all the white bulbs in the house, this light is dark yellow and yellow, it hurts my eyes!" Chen Xu looked at the lonely light bulb hanging in mid-air from the ceiling with a wire, and said without being salty.

"Done? Hot food for you in the kitchen! Quickly brought it out and ate it, your sister-in-law said that you haven't eaten all day today, and you don't know if you are hungry regardless of work. Chen Weiguo raised his head when he heard the sound, and saw his younger brother standing next to the TV cabinet with his hands and arms in his hands, throwing the Wen Jiàn in his hand on the coffee table and snorting at the kitchen.

"Don't say it, I'm really hungry." Chen Xu touched his deflated belly, licked his lips, turned around and went to the kitchen

The kitchen is old and simply furnished. There is only a red brick and cement stove and a sink, and on the opposite side is a red-painted glass cupboard, next to which are hundreds of briquettes, and behind the door is a liquefied gas tank.

On the coal stove next to the sink is a cast aluminum pressure cooker, which is sizzling hot gas.

Chen Xu put the pressure cooker in the sink, pulled out the gas plug to dissipate the steam inside, and unscrewed the lid of the pot, and the aroma of meat came to his nose.

The dish is a simple stir-fried pork with chili pepper and baby cabbage, which is mixed with white rice in a large bowl and steamed in a pressure cooker. In this era, materials are scarce, and the country has not yet started the vegetable basket convenience project, which is not as good as the chicken, duck and fish meat that can be eaten at every meal in later generations. If it weren't for serving Chen Xu, the eldest brother's family would only eat meat once every three or five days.

Wet your fingers and take out the hot bowl, pull out a pair of chopsticks and use a rag to pad your palm and carry the bowl out of the kitchen.

Put the vegetable bowl on the coffee table, throw the rag aside casually, and Chen Xu squatted next to the coffee table and ate it.

The meat is very fragrant after steaming for a long time, and the cabbage is boiled and has the same flavor as pig food, but for people who have been hungry all day, everything they eat is fragrant.

Looking at Zhengxiang's younger brother who was eating, Chen Weiguo took off his glasses and sighed: "Say that you are not doing your job!" Quietly stealing back top-secret information from the Soviet Union, my father has been detained in Beijing for almost half a month, and he doesn't know how things will ferment. Say you're a straw bale who doesn't know how to learn! But you can design products independently, and the design drawings you draw are some of the numbers I don't understand. The more you look at the fan blades, the more you look at it, the more it is not simple, an electric fan, can you use such a complex design? ”

"Cut! If even a layman like you could understand the design I draw, then my five years of the Soviet Union would have been in vain. Chen Xu sucked a cabbage into his mouth with a snort, shook his head proudly.

"You kid don't squint at people, big brother and I are also a graduate of the University of Science and Technology of China, and it's no problem to understand a drawing." Chen Weiguo sorted out the messy text on the coffee table and said dissatisfied.

"I really can't see that big brother, you are actually from a research background, I thought you relied on your grandfather's promotion to become this deputy factory director!" Chen Xu took a big bite of rice and teased vaguely.

It is not surprising that Chen Weiguo was an engineering student, and during the First Five-Year Plan period, China imported 156 projects from the Soviet Union, allowing China to build its own heavy industry base from scratch. However, after the introduction of equipment, it was found that there was a shortage of people to operate the equipment, especially the design and development personnel, and the research and development capabilities were far behind those abroad. In order to cultivate the science and engineering talents urgently needed by New China, the state began to build key engineering universities to train engineers for the domestic heavy industry sector. These key universities are the foundation of the later "211 Project", and the higher-level "985 Project" is the essence of national education.

The construction of key universities has a great impact on the country and establishes the idea of an industrial country. The previous top leaders of the country except for Grandpa Mao and Zhou are always liberal arts students, and the next few are all engineering students, Jiang always plays with machinery and electronics, Hu Boss is engaged in water conservancy, and Wen is always mining......

The country's leaders are all engaged in industry, and in this academic atmosphere, it is not for nothing that China later became the world's factory!

Chen Weiguo lay on his back on the sofa, yawned, and frowned: "Xiao Wu, I see that your design drawings are so complicated, will you encounter difficulties in the production process?" If you don't have enough manpower, just tell your eldest brother and I'll transfer someone from another workshop. ”

"Don't use it for the time being, everything is difficult at the beginning, I can't manage it when there are too many people, and the workshop of more than 50 people is enough for me to toss." Chen Xu shook his head and refused the kindness of his eldest brother, and suddenly he looked at a newspaper spread out on the coffee table and saw a piece of news that made him pay attention: "The Affiliated Research Institute of Huxiang University will participate in the Tokyo Industrial Fair in October as a representative of Huxiang Province!" ”

Chen Xu threw away his chopsticks and read the short news message twice, his face was full of light: "I can't imagine that there is such a thing as an industrial expo, which is still held in Tokyo." Looking at the content on the news, the state seems to ask each province to come up with a few fist products, and then organize a group to participate in this industrial fair. ”

Chen Weiguo had obviously read this newspaper, so he responded nonchalantly: "This is a propaganda matter, and the country urgently needs foreign exchange to introduce advanced foreign production technology." Therefore, it has become a top priority to sell our products abroad, and this kind of industrial fair happens to be an opportunity to launch our national brand in the world. ”

"Why doesn't our factory participate, why should a university research institute be a representative?" Chen Xu picked up the newspaper and read it a few times again, his whole body trembled with excitement, he felt that he seemed to be able to use this expo to make a big profit!

"What are we going to attend? Is it the broken electric fan that your workshop is producing now, or the pressure cooker and tractor? The pressure cooker you just saw in the kitchen was made by our factory, do you think it can be brought to the booth of the expo for the people of the world to see? Chen Weiguo took a sip of tea, put on his glasses again, and studied the text on the coffee table. For him, this kind of news is just an after-dinner conversation, and it does not arouse his interest.

"I didn't have it before, but I don't have it now!" Chen Xu waved the newspaper, leaned in front of the eldest brother, and said happily: "The electric fan I designed uses so many new technologies, even the bearings inside are designed with military standards, and it is possible to win a gold medal at this expo!" ”

Chen Weiguo glanced at the newspaper, shrugged his shoulders and said: "It's useless, I've seen your design drawings, the electric fan is indeed very beautiful, but now there are only forty days before the opening of the expo, and it is too late to produce!" ”

"Big brother, your attitude is wrong, we are a military factory that builds tanks, and forty days is not for you to design a tank, a simple electric fan, you can't even say that you can't do it, is there any hope for such a factory? It's better to close the door as soon as possible, dismiss the workers, and go back to farming. Chen Xu threw the newspaper onto the sofa, very dissatisfied.

"Haha, foreigners are putting advanced air conditioners as exhibits, wouldn't it be a shame for us to take an electric fan, let's forget it!" Chen Weiguo shook his head, the meaning of refusal was already very clear.

Keeping the factory running smoothly is already a big headache for him, and he won't let his younger brother come and toss the already fragile factory.

Chen Xu smashed his mouth and persuaded: "My eldest brother, you misunderstood what I meant, we went to the exhibition not to show foreigners our electric fan, but to let them see the military technology contained in our electric fan." Like that kind of expo is also a grand event for scientific researchers from all over the world, as long as you know a little bit of technology, you can see that our factory is not simple, and this reputation will be out! If you have a famous electric fan, you won't have to worry about selling it, and won't life in the factory be easier if you make money? ”

"I just think that the electric fan you designed is wrong, especially the blades of yours don't look like an ordinary design, they are simply the propellers of warships."

Chen Weiguo stood up from the sofa suddenly, squinted his eyes and snorted coldly: "From the fact that you dared to steal the top-secret intelligence of the Soviets, I knew that you kid was a bold man, and you honestly explained to me whether the design of this propeller was also stolen from the Soviet Union's military intelligence?" ”

Chen Xu also slapped the coffee table and said-for-tat towards the eldest brother: "You can underestimate my personality, but you can't insult my design." As far as Lao Maozi's design level can be compared with me, you don't look at how exquisite my propeller is, can it be designed by ordinary people?

"According to you, this blade is really a propeller! Whether it is your boy's design or the design of the Soviets, I must hand over the drawings to the Naval Research Institute in Beijing for review, if it involves military secrets, this electric fan cannot be built. "Chen Weiguo is a steady person, he knows that his younger brother has secrets in his head, so he must be safe in anything related to military secrets, and he can't follow Chen Xu to mess around.

Chen Xu knew that it was a bad dish as soon as he heard it, if this drawing was taken to the Naval Research Institute, those experts would definitely instantly turn into a red-eyed rabbit when they saw this drawing, and the layman would see the lively insider's doorway, but anyone who was engaged in ship design could see the military value of this propeller at a glance, if they determined the value of the drawing, not only would the electric fan be in vain, but they might also be besieged by them.

Chen Xu is engaged in intelligence, and naturally knows the value of the propeller, but with the current metallurgical technology in China, this propeller blade cannot be made in at least ten years, and it is meaningless to hold the drawings for things that cannot be produced.

It's just that Chen Xu didn't know that the thinking of his intelligence officers in later generations was too ahead of the times, and intelligence was a thing that paid attention to timeliness, and neither outdated nor advanced intelligence could give full play to its greatest value.

Relying too much on previous experience made Chen Xuyan underestimate this propeller design drawing, he didn't know that in this era, the propeller design drawing was no problem to change to a nuclear submarine!
