When Chen Zihao and Liu Wei confronted Wang Sheng and Luo Zhang, Lu Jiadong, who had been in the trial unit for nearly half a month, also returned to the Wanshan Factory, and the Type 78 assault rifle of the Wanshan Factory was widely praised by the trial unit for its advantages of high firepower, strong power, high reliability, and convenient maintenance, and even some soldiers did not want to use the original 56 Chong and 56 and a half after hitting the target several times with the Type 78, so that other units that had not tried it frequently reported to their superiors and asked to be equipped with Type 78 assault rifles.

Of course, the Type 78 assault rifle as a new gun, there will be some problems, such as the left hand is not very convenient to move fast or slow and so on, but the problem is basically ergonomics, in terms of specific performance, Lu Jiadong did not get a feedback.

However, the procurement department of the army gave Lu Jiadong an opinion, that is, the procurement cost of the Type 78 assault rifle was too high, and there were nearly 5 million troops in the country at that time, and if each person had a 500 yuan assault rifle, this would be tantamount to an astronomical amount for the army that only had so much military expenditure every year, and he would not dare to buy it even if it was good.

At that time, in order to ensure the quality and requirements of this batch of trial assault rifles, Wanshan Factory used a large number of parts of this batch of guns using cutting technology, which made the firearms not only complex to produce, but also costly, and not suitable for large-scale production and equipment at all, so on the way back, Lu Jiadong was thinking about how to simplify the production process and reduce the cost without affecting the basic performance.

At this time, Lu Jiadong was sitting in the conference room of the factory, reporting the trip to the party committee of the factory, and also talked about the way to improve the process and reduce costs:

"It is best to use a large number of stamping processes for the parts of our firearms, so that it is simple and convenient to manufacture, and use low-nickel alloy cannon steel that has been widely used in materials to reduce costs, so that I calculated, our single cost can be reduced to about 200 yuan."

"Factory director, factory director!" Lu Jiadong was talking to the factory director Chen Zhen and the secretary Xinghua about how to reduce the cost of firearms, when Zhao Wei, the director of the factory office, rushed in in a hurry, and when he saw Chen Zhen, he said very eagerly:

"It's fighting, it's fighting!"

"Director Zhao, what's going on!"

After listening to Lu Jiadong's question, Zhao Wei calmed down a little, but his nervous expression still did not subside: "Xiao Lu, you came back just in time, Chen Zihao and Liu Wei from our factory have a fight with Wang Sheng and Luo Zhang from Guinan Factory!"

As soon as Zhao Wei's words fell, Chen Zhen slapped the table violently and stood up: "Chen Zihao, this little rabbit cub, it doesn't matter if he doesn't learn the precision machine tool well, he still dares to fight, go, where to take a look, see how I clean up this rabbit cub!"

Chen Zhen as a leading cadre in the factory has always been strict with himself, especially for his family, never give special care to his family in the factory, not only that, but he also often asks Chen Ziyue Chen Zihao to learn more, originally Chen Zihao to learn precision machine tools, Chen Zhen is very happy.

But after studying for half a month, he couldn't even process a qualified workpiece, which made Chen Zhen very faceless, and always felt that his son didn't put his mind into learning, and his heart was very angry.

Chen Zhen has a temper when he ignites the fire, but Lu Jiadong is not like this, he knows Chen Zihao and Liu Wei, and knows that they will not easily beat people, there must be something strange in this, so when Chen Zhen got up and was about to go out, Lu Jiadong hurriedly got up and stopped him:

"Factory director, Zihao and Liu Wei I understand, they are not the kind of people who do it after saying a few words, there must be something strange in this!" After speaking, Lu Jiadong turned his head and looked at Zhao Wei: "Director Zhao, how is the situation now?"

"What else, the two groups of people were temporarily pulled away by Director Qiao, and they were scolding each other!"

Hearing this, Lu Jiadong couldn't help frowning, and at this time, Gao Xinghua next to him also looked anxious: "It's so serious, Lao Chen, I think let's go somewhere to see! Xiao Lu, you go with you!"

In this way, a few people left the factory department and hurried towards the military workshop

"Damn, you two moths, you are doing things on the machine for some subsidies! Come here, see how Lao Tzu repairs you!" Just as Chen Zhen and Lu Jiadong hurried towards the military workshop, Chen Zihao here was scolding Wang Sheng and Luo Zhang opposite through the blocking crowd.

Wang Sheng was hit by Chen Zihao's sudden punch on the bridge of his nose, and his face was full of peach blossoms in an instant, Chen Zihao made such a move, Liu Wei no longer hesitated, and kicked Luo Zhang with a, Wang Sheng and Luo Zhang were originally doing technical work, and they were not the opponents of the strong Chen Zihao and Liu Wei at all, so the form was quickly one-sided, and Wang Sheng and Luo Zhang fell into a masochistic mode.

Fortunately, the other workers in the workshop and the workshop director Qiao Junfeng came in time, otherwise Wang Sheng and Luo Zhang would have to be sent to the factory health center, even so, Wang Sheng and Luo Zhang were covered with blood, and fell to the ground and snorted,

However, the two did not stop there, especially Wang Sheng, when he saw someone pulling Chen Zihao and Liu Wei apart, it was like beating chicken blood, arrogant, looking at Chen Zihao with an angry face and scolding back:

"Which ear of your ears heard that we were going to subsidize, and that eye saw that Lao Tzu was a ghost, you don't learn well and rely on others, are all the people in your Wanshan Factory your virtue?"

Hearing Wang Sheng's words, Chen Zihao was even more angry: "Don't think that you are doing those things in the guest house that others don't know, tell you that you don't want people to know, unless you don't do it!" Saying that, Chen Zihao shouted at Qiao Junfeng, who stopped him: "Get up, Lao Tzu has to beat him all over the ground today!"

"Chen Zihao, what do you want to do!" Just as Chen Zihao was about to break free from Qiao Junfeng's obstruction, Chen Zhen, who had already come to the door of the workshop, suddenly appeared in front of everyone, and when he saw Chen Zhen coming, Qiao Junfeng couldn't help wiping the sweat on his face:

"Director, you're finally here!"

"Director Chen, this is a good employee of your Wanshan Factory, your good son has done a good job, he doesn't learn well, he still blames others, and he even beats people, you look at the beating of the two of us, what should I do, you look at it!" Chen Zhen's arrival made Wang Sheng feel that things had taken a turn for the better, without saying a word, he pointed to the blood stains on his face and followed Chen Zhen, and Luo Zhang next to him also hummed just right, a typical tragic image of being forced and tortured.

Looking at the appearance of Wang Sheng and Luo Zhang, and listening to Wang Sheng's words, Chen Zhen's face was already gloomy like water, and at this moment, Chen Zihao was also very unconvinced:

"Dad, they used their hands and feet on the machine for a high subsidy, otherwise Liu Wei and I wouldn't have been able to learn for half a month."

"Shut up!" Before Chen Zihao finished speaking, Chen Zhen shouted violently, which scared Chen Zihao into a thrill, Wang Sheng saw this scene and instantly felt that he had a backer, and he had no scruples when he spoke:

"Hmph! If you can't learn well in half a month, it means that you are stupid! I dare to say, if it weren't for the two of us, your Wanshan Factory wouldn't have opened this machine, but I haven't even seen it!"

At this time, Lu Jiadong was pulling Liu Wei aside to understand the reason, he knew Liu Wei very well, knew that he was a young man who liked technology and was very self-motivated, he couldn't do it easily, and what he said was more credible, just when Liu Wei was talking about the ugly things about Wang Wei and Luo Zhang, Wang Sheng's words reached Lu Jiadong's ears, and Lu Jiadong just frowned:

"JT-894 precision boring and milling machine, no big deal!"

When Lu Jiadong was an intern in the arsenal, let alone seen it, he didn't know how many times he had used it, although his voice was not loud, but it really reached Wang Sheng's ears, which made Wang Sheng couldn't help but be shocked on the spot, who is this young man, how come he has never seen it, and he didn't even tell Chen Zihao and Liu Wei about the model of the machine, how did he know?

But before Wang Sheng could figure out what was going on, he saw Lu Jiadong walking towards the two precision machine tools, Wang Sheng couldn't help but chuckle in his heart, and an inexplicable sense of fear suddenly came to his heart.

Lu Jiadong was not afraid of Wang Sheng, he came to the JT-894 precision boring and milling machine tool, lightly touched the machine tool parts with his hand, and then nodded, then he put his eyes on the optical system of the machine tool, carefully looked at the optical scale, rotated a few times, and found that the numbers of the large disk were intact, but the numbers of the small disk were scratched, and only the two table codes of 0 and 10 and countless scale marks were retained.

Then he looked at the lenses again and found that the bottom lenses were a little blurry, so he shouted at Liu Wei behind him: "Liu Wei, help me with that bit of alcohol!"

When Lu Jiadong said this, Wang Sheng couldn't help pinching the pocket of his jacket, and even Luo Zhang, who was snorting in pain on the ground, stopped shouting, Liu Wei quickly brought the alcohol, Lu Jiadong cleaned the bottom lens with a cotton swab dipped in alcohol, and then wiped it with a clean cloth, and then adjusted the optical scale a few times.

He turned his head and said lightly to everyone present: "The machine tool is indeed passive, the lenses are deliberately soiled, and the optical scale is deliberately flowered" Saying that, Lu Jiadong turned his face to Wang Sheng, and said lightly: "Master Wang, am I right!"

"What's right, the machine itself is an old machine, and scratching is normal!"

"Oh?Then why do you only tell Zihao that the accuracy of the machine is only 0.0002mm, why do you still hide the value of 0.00025mm?

At this time, Wang Sheng was completely stunned, he didn't expect the young man in front of him to know the accurate and precise value of the machine tool, but Lu Jiadong didn't give him too much time to be surprised, and said to Liu Wei next to him:

"Go and see if they have alcohol cotton on them, if they don't use alcohol cotton when they operate, they can't make parts at all!"

As soon as Lu Jiadong's words fell, Liu Wei rushed forward with an arrow, picked up the two of them one by one like a chicken, and found two small packets of alcohol cotton on them in the blink of an eye, so that the truth was revealed.
