It is said that there is only a small part of the factory outside the base of the Nine Courtyards, and the important facilities, technical reserves, and strategic reserves are all in the caves inside the mountain.

The main task of the base is to stock up on equipment and technology, and even the nuclear power plant, which has only been built for a short time, is in the deepest part of the mountain!

The terrain of the base is hidden, and after careful investigation and design by Liu Suzhi and many returned comrades, there will be no worries about natural disasters when the workshop is built at the bottom of the valley.

Behind the valley is Daba Mountain, which stretches in the direction of the Qinling Mountains, and the main body of the base also extends to the Qinling Mountains, it is said.

From the dormitory to the workshop at the bottom of the valley, it is connected by a gravel road only a few meters wide, and over the years the road has been paved with cinders from unknown places, making the road much smoother and not too difficult to walk.

"Stop, what are you doing?" As soon as they saw the bright light of at least a hundred watt light bulbs at the door of the workshop, the two of them were frightened by a loud voice.

"9327 workshop technical officer Yang Shan, Liu Yijiu." When Liu Yijiu was about to turn around and flee in the direction of the dormitory, Yang Shan replied calmly, and turned the flashlight in his hand to his face.

"What are you doing at the factory without sleeping at night?" Hearing Yang Shan's answer, the tone of the questioner was much better.

The small door on the edge of the factory gate made of iron railings opened, and a middle-aged man in a white uniform appeared under the bright light at the factory gate.

"Isn't this Director Xu? Aren't you home? Why are you on duty today? Yang Shan pulled Liu Yijiu to the factory gate while greeting the middle-aged man in uniform under the light.

This guy is Xu Zhiyuan, an officer of the base security section!

There are three security systems in the base. Internally, the internal security of the base is responsible, and the level is similar to that of the public security bureau outside, but it is much more awesome than the public security bureau outside. If the people in the base commit something outside, the police station outside will have to be handed over to the base internal security to deal with.

The other set is the base guard, which is composed of the capital garrison, which closely defends the area within a radius of dozens of miles around the base.

The third set, and the most useless set, is the Security Section. Why there are external guards, internal guards, and there is a security department, no one knows.

Maybe it's to arrange some veterans.

"You young people, you are indeed the successors of socialism! Before five o'clock, I came to the workshop to practice skills! Especially Xiao Yang, who often comes so early! I must write a letter of commendation to the leaders of the base. You are a role model for all the people in the entire base, the power of example is infinite, let more people learn from you......" Xu Zhiyuan heard Yang Shan's words, and immediately praised him.

His words made Liu Yijiu keenly aware that Yang Shan's old face had turned red.

Yang Shan went to the workshop, just to make a show, earn performance, and hope to be set up as a pacesetter, so that he can be upgraded quickly! Many people are now living in the base, and if they want to receive higher wages and more subsidies, they must be role models, and this is the shortcut.

In particular, some of the skilled workers and experts who migrated from Shanghai in the first place, many of whom want to return to their cities.

Yang Shan's role model has become very prominent.

"Director Xu has won the award! We are always ready for revolution! Yang Shan stood upright and saluted Xu Zhiyuan with a crooked military salute.

"The high gorge comes out of the Ping Lake, and the high-rise buildings rise from the ground. Only after continuous practice can you turn other people's experiences into your own ......" Almost without thinking, Liu Yijiu stood straight and answered Xu Zhiyuan's words.

Hearing this, Xu Zhiyuan saluted the two of them, then opened the factory gate and made a gesture of invitation to the two.

Liu Yijiu was a little confused, what was going on, and Yang Shan next to him quietly gave him a thumbs up.

Liu Yijiu is unfamiliar with everything in the base, and if he is not accompanied by Yang Shan, he will really have to be blind when he enters here.

Looking down at the halfway point of the dormitory area, I didn't think it was too big, and when I entered the workshop, I found that it was far wider than I imagined.

The entire bottom of the valley is occupied by Soviet-style brick and wood structure factories, each of which is less than ten meters apart. There are six workshops with a width of more than 10 meters and a length of 40 meters in this valley! If you don't have Yang Shan, just looking for a machining workshop will give Liu Yijiu a headache.

At the door of the workshop, there is an internal guard sentry!

"Let's go directly to the material warehouse on the side, find the right material and go to the machining workshop, by the way, what material do you want for that thing?" Don't make it a ...... that doesn't have much reserves in the base."

"Don't worry, I know what to expect. Brother Yang, there are aviation duralumin bars imported from the Soviet Union in the base, right? A diameter of twenty-two to twenty-five is fine, but it is not too long, four sets, and it is only five or six hundred long...... "Liu Yijiu naturally knows that in China in this era, it is basically impossible to get some good materials.

Since I wasn't sure what materials were in the base, I could only casually say a material that was easy to process and should be stocked in the base, and this muffler was just a disposable.

If there is a suitable mechanical equipment and suitable materials, you can use a steel plate with a thickness of 1mm to cut, and after drilling the hole, the burrs on it are cleaned, polished and smooth, and then rolled and welded, which is easier and more durable than machining.

In order to save time and process easily, we can only use aviation duralumin with high hardness and good processability.

"My God, big brother, there are not many imported materials from the Soviet Union, if Director Xie knows, he will have to destroy our ......" Hearing Liu Yijiu's words, Yang Shan suddenly jumped up.

"Isn't it just a bit of aviation aluminum? Don't worry, when we're full, we can directly come up with the formula, and what can he say at that time? With a little aluminum, and give him a production process and formula, will he not do it? Liu Yijiu said indifferently.

Although he didn't know who Director Xie was in Yang Shankou, and he didn't know how many directors there were in this base, Liu Yijiu didn't think it would be more difficult to deal with than Su Mingyi.

"No, it can't be like this. There is no problem with entering the material warehouse to go to ordinary materials, imported materials are all materials transported from outside, which are used for research and analysis by material experts at the base. Let's change it......" Yang Shan doesn't think what Liu Yijiu said can be done.

There are hundreds of experts from all walks of life in the base, and for many years, they haven't figured out the formula and production process of Lao Maozi.

A new hairy boy dared to speak out about the top aviation aluminum in the Soviet Union!

Seeing that Yang Shan was unwilling to accompany him to the material library no matter what he said, Liu Yijiu was also speechless. If he knew where the materials were, would he not?

What's more, they have this right! Even if there is no result, the most you can do is be warned. Leaders can't crack down on the progress of grassroots technicians, right?

Yang Shan did not agree to make aviation duralumin no matter what Liu Yijiu said.

"Revolution requires a fearless spirit of sacrifice, and besides, history is made by the people! Brother Yang, when we get this material, we will create history, figure out the material formula and production process, and completely change the history of our domestic strategic materials that cannot be produced domestically, fill the domestic gap, and when the time comes, we will be the heroes......"

"Well, I don't read as much as you do, don't coax me here. How did I meet you, this fairy board! When Yang Shan heard Liu Yijiu's words, he was really moved.

There are many opportunities to make meritorious contributions, but obviously not for people like them who don't know anything and don't have a master to take them.

He doesn't think what Liu Yijiu said about making the material, production process and formula is reliable, but Liu Yijiu's muffler should be reliable!

When the time comes, if Liu Yijiu gives him some credit for this......

The base does not stipulate that ordinary technicians are not allowed to use strategic materials in research experiments.

The risk is small, the benefit is large, this risk is still worth taking!

If you can't eat enough to get a gun, take the biggest risk, design and process the muffler is Liu Yijiu, and he should get the materials, and he must go.

As for Rotong's unlucky kid, he always followed behind their buttocks, pointing and hitting wherever he wanted. If he followed them now, he wouldn't have to worry about it.

"Gollum ......" Just when the two were at a stalemate, there was also a gurgling sound from Yang Shan's stomach.

There was no oil or water in his stomach, he hadn't seen meat for a long time, and he hadn't been hungry since he went to college, and he couldn't stand it anymore when he experienced that taste again.

"This material, let's use it to analyze the chemical composition and physical properties of Lao Maozi material, just take it out. As long as there are experimental results, who cares if we make the whole material into shavings or what's wrong? Taking a step back, there are not a few weeks of time, who will run to the warehouse to count the inventory? My teacher has some research on this, and when the time comes, it will prove that we have done it seriously, and if the leader asks us to continue to do it, then we can do it seriously. Seeing that Yang Shan was entangled, Liu Yijiu continued to fool him.

"What's more, it's for meat!"
