When Chen Zihao and Liu Wei confronted Wang Sheng and Luo Zhang, Lu Jiadong, who had been in the trial assembly unit for nearly half a month, also returned to Wanshan Factory. The Type 78 assault rifle of Wanshan Factory was widely praised by the test assembly unit for its advantages of high firepower, strong power, high reliability, and easy maintenance. Some soldiers even no longer wanted to use the original 56 and 56 and a half after hitting the target several times with the Type 78, which caused other troops that had not tested frequently to report to their superiors and required the Type 78 assault rifle to be equipped.

Of course, as a new gun, the Type 78 assault rifle will have some problems, such as the speed and speed of the gun when holding the left hand, and so on, etc., but the problems that exist are basically about ergonomic efficiency, and Lu Jiadong did not receive any feedback on specific performance.

However, the army's procurement department gave Lu Jiadong an opinion, that is, the procurement cost of the Type 78 assault rifle was too high. At that time, there were nearly 5 million troops nationwide. If one person had an astronomical assault rifle worth 500 yuan, it would be astronomical for an army with only a little military expenditure every year. Even if it was good, he would not dare to buy it.

This opinion is the most important gain from Lu Jiadong's trip. At that time, in order to ensure the quality and requirements of this batch of trial-made assault rifles, Wanshan Factory used a cutting process to produce a large number of components of this batch of guns, which made the firearm not only complex production, but also high cost, and it was 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 factory meeting room, reporting on the trip to the factory party committee, and also talked about ways to improve the process and reduce costs:

"It is best to use stamping technology in our gun parts in large quantities, so that it is simple and convenient to manufacture. Use low-nickel alloy gun steel that has been widely used in terms of materials to reduce the cost. In this way, I calculated that our single-piece cost can be reduced to about 200 yuan..."

"Manager, factory director!" Lu Jiadong was talking to factory director Chen Zhen and secretary Gao Xinghua about how to reduce the cost of firearms. Director Zhao Wei, director of the factory office, rushed in and said anxiously when he saw Chen Zhen:

"Fight, fight!"

"Director Zhao, what's going on!"

After hearing Lu Jiadong's question, Zhao Wei calmed down a little, but his nervous expression still did not retreat: "Xiao Lu, you are back just in time. Chen Zihao from our factory and Liu Wei from our factory are fighting with Wang Sheng from Guinan Factory and Luo Zhang!"

As soon as Zhao Wei finished speaking, Chen Zhen slapped the table suddenly and stood up: "It's okay if Chen Zihao doesn't know how to learn precision machine tools well, but he still dares to fight. Let's go and see where to go, see how I deal with this bastard!"

As a leading cadre in the factory, Chen Zhen has always been strict with himself and is even more so with his family. He never gives special care to his family in the factory. Not only that, he also often asks Chen Ziyue and Chen Zihao to study more. Originally, Chen Zihao went to learn precision machine tools, and Chen Zhen was very happy.

However, after half a month of studying, he couldn't even process a qualified workpiece, which made Chen Zhen look embarrassed. He always felt that his son had not put his mind to learn, and he felt very angry. Now that he heard that he had started fighting with others again, he was even more angry and vowed to teach this incompetent son a lesson!

Chen Zhen is just igniting the fire, but Lu Jiadong is not like this. He knows Chen Zihao and Liu Wei and knows that they will not hit people easily. There must be something strange about this. So when Chen Zhen got up and was about to go out, Lu Jiadong quickly got up and stopped him:

"Director, I understand Zihao and Liu Wei. I am not the kind of person who just says a few words and takes action. There must be something strange here!" After saying that, Lu Jiadong turned his head to look at Zhao Wei: "Director Zhao, what's the situation now?"

"What else can it be done? The two groups of people were temporarily pulled away by Director Qiao and were scolding each other!"

Hearing this, Lu Jiadong couldn't help frowning. At this time, Gao Xinghua next to him was also anxious: "So serious, Old Chen, I think we should go where to go! Xiao Lu, you go with me too!"

Just like this, a few people left the factory and hurried towards the military workshop...

"Damn, you two borers are tampering with the machine for the sake of subsidy! Come here and see how I repair you!" Just as Chen Zhen and Lu Jiadong hurried towards the military workshop, Chen Zihao here was cursing Wang Sheng and Luo Zhang opposite him through the blocking crowd.

Wang Sheng was on the middle of the bridge of his nose by Chen Zihao, and his face was filled with peach blossoms. After Chen Zihao took action, Liu Wei no longer hesitated and kicked Luo Zhang to bite the shit. Wang Sheng and Luo Zhang were originally doing technical work, and were not the opponents of the strong Chen Zihao and Liu Wei, so the situation quickly turned one-sided, and Wang Sheng and Luo Zhang fell into a abused mode.

Fortunately, other workers and 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 in blood and fell to the ground and hummed.

However, the two did not calm down, especially Wang Sheng. When he saw someone pulling Chen Zihao and Liu Wei away, he became arrogant as if he was injected with chicken blood. He looked at Chen Zihao with an angry face and cursed back:

"Which ear is yours we need subsidies. That eye sees me doing something wrong. If you can't learn well, you still rely on others. Are you all the people in Wanshan Factory doing this kind of virtue?"

After hearing Wang Sheng's words, Chen Zihao was even more furious: "Don't think that you are doing things in the guesthouse that others don't know. Tell you to think about others and not do it yourself!" As he said that, Chen Zihao shouted loudly at Qiao Junfeng who stopped him, "Get up, I have to beat him up today and look for teeth all over the floor!"

"Chen Zihao, what do you want to do!" Just as Chen Zihao was about to break free from Qiao Junfeng's obstacle, Chen Zhen, who had already arrived at the door of the workshop, suddenly appeared in front of everyone. Seeing Chen Zhen coming, Qiao Junfeng couldn't help but wipe the sweat from his face:

"Manager, you are finally here!"

"Director Chen, this is your good employee of Wanshan Factory. Your good son does good things. If you don't learn well, you always blame others for beating people. Look at what to do if you beat us. You can do it!" Chen Zhen's arrival made Wang Sheng feel that things had a turnaround. Without saying a word, he followed Chen Zhen and pointed at the blood stains on his face. Luo Zhang next to him also hummed just right, and he looked like a tragic image of being forced and tortured.

Looking at Wang Sheng and Luo Zhang's appearance, after hearing Wang Sheng's words, Chen Zhen's face was already gloomy. At this moment, Chen Zihao said unconvincedly:

"Dad! They tampered with the machine for the sake of high subsidies, otherwise Liu Wei and I would not have been able to learn for half a month..."

"Stop!" Before Chen Zihao finished speaking, Chen Zhen shouted loudly, which scared Chen Zihao. When Wang Sheng saw this scene, he felt that he had a backer and spoke even more without any scruples:

"Hmph! If you can't learn well for half a month, it means you are stupid! I dare say that if it weren't for us, you Wanshan Factory wouldn't even have seen this machine!"

At this time, Lu Jiadong was pulling Liu Wei aside to understand the reasons. He knew Liu Wei very well. He knew that he was a young man who liked technology and was very motivated. He would not do anything easily and said something was more credible. Just as Liu Wei was talking about the scandal of 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 in an internship in the arsenal, he had seen it, and he had used it many times. Although his voice was not loud, it really reached Wang Sheng's ears, which made Wang Sheng startled on the spot. Who is this young man? Why have he never seen it? He didn't even tell Chen Zihao and Liu Wei the model of the machine. How did he know?

But before Wang Sheng could figure out what was going on, he saw Lu Jiadong stepping towards the two precision machine tools. Wang Sheng couldn't help but feel a sudden slap in his heart, and an inexplicable sense of fear suddenly surged into his heart.

Lu Jiadong was afraid and not afraid. He came to the jt-894 precision boring and milling machine tool, gently touched the machine tool without components with his hand, and nodded. At this time, he landed his eyes on the optical system of the machine tool, looked carefully at the optical scale meter, and rotated it a few times. He found that the numbers on the large disk were intact, but the numbers on the small disk were scratched, leaving only two meter numbers 0 and 10 and countless scale lines.

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

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

Then he turned his head and said lightly to everyone present: "The machine tool is indeed passive, the lenses are deliberately dirty, and the optical scale meter is deliberately made to make flowers." As he said that, Lu Jiadong turned his face to Wang Sheng and said lightly: "Master Wang, am I right?"

"What's right? The machine tool itself is an old machine, and it's normal to scratch it!"

"Oh? Then why do you only tell Zihao and the others that the accuracy of the machine is only 0.0002mm, why do you still hide the value of 0.00025mm? Could it be that 5 of 2 be eaten by you?"

At this time, Wang Sheng was completely stunned. He didn't expect that the young man in front of him would actually know the accuracy of the machine tool. However, Lu Jiadong did not give him too much time to surprise him 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 to wipe them when they operate, they will not be able to make any parts!"
