Thank you to Brother Yin Zhiping for your reward and support again, and thank you to Cheese for changing your destiny, accip, maohai, and Zixing Yaoyue for your reward and support, thank you! ! ! ! ! In addition, thank you brother for your evaluation vote, please add it to your collection, please recommend it, please support me, please hug me, \(^o^)/~! ! ¡ª¡ª ¡ª¡ªSince the drawings have been drawn , Chen Er took action without hesitation, because this is his own independent research laboratory, so he doesn't need to ask anyone for instructions. Wang Yong was also very positive. At this moment, he was completely convinced by Chen Er. Several people have divided the labor and cooperated. Compared with the old machine tools in the past, the performance of the new machine tools has been greatly improved. Not only the precision of the parts has been improved, but the processing efficiency has also made a big leap. It is also more comfortable to stand up. Chen Er is responsible for the processing of the barrel, hammer, sear, hammer spring, sear, etc. Because these internal parts of the firearm will directly affect the performance of the firearm, for the sake of safety, Chen Er chose to do it himself. Fingering. As for the other parts, Chen Er handed them over to Wang Yong and Li Jun. They had ready-made drawings. Moreover, they were familiar with the operation of this new machine tool, so it should not be difficult to make them. The afternoon passed quickly, and several people had entered a state of selflessness. Murong Wan and Wen Jing saw that they could not be of much help here, so they simply went to bring them food. Until Murong Wan and the others came back, Chen Er and the three of them were still busy in front of the machine tool. This is the life of a military engineer. Many times once you have some ideas, you will definitely forget to eat and sleep to complete them. Because you don't know that once you stop, the original thought may become difficult to remember. After waiting for more than half an hour, Wen Jing said first: "Wan'er, let's ask the three of them to eat first. The food is almost cold, and we can't heat it up here." Murong Wan nodded and walked to Chen Er and whispered, "You guys should eat first, the food will be cold soon." Chen Er happened to finish a part in his hand. He looked up at the hanging watch and was stunned. Unexpectedly, it was already half past six in the afternoon. He had been working for four or five hours. No wonder his arms felt It's a little sore. At this time, he felt that his stomach was protesting against him. He smiled and said, "Okay, wait until I call them two. Time flies so fast." When he came to Li Jun's side, Chen Er coughed. He said at once: "Take a rest for a while. I think you are almost done. Anyway, it will definitely not be finished today. I still have several parts that have not been processed. Let's go to eat first." After listening to Chen Er's words, Li Jun also stopped, looked at the time and then at Chen Er and said, "Second brother, why is it already this time? There is still food in the cafeteria. I might be hungry today." Chen Er smiled Said: "Don't worry, your Wenjing presence will really make you hungry. The two of them have already brought us food, so go and eat it quickly." Li Jun ran over in a hurry. , and ate happily while chatting with Wen Jing. When Wang Yong saw Chen Er and the others stopped, he put down the parts in his hands and said, "It's already so late. I'll go to the canteen to eat. I'll come back early tomorrow morning." Chen Er looked at what he was making. He took his hand and said, "Come eat with us. The two of them also bought your share of the meal. Besides, there is nothing in the cafeteria at this time. You don't want to spend the night hungry." Wang Yong thought the same thing, so he could only follow Chen Er to the resting place next to him, and said to Murong Wan and Wen Jing, "Thank you so much, otherwise I would be really hungry tonight." After saying that, he picked up the lunch box. After eating, it seemed that I was indeed hungry. Although the machine tools are much better than before, it is still a laborious job. Moreover, they only work for an afternoon. If they were not young and strong, they would probably be unable to withstand it. As soon as they stopped, all three of them felt extremely weak and exhausted. After finishing the meal, Li Jun put the lunch box aside casually and said, "It was great. This afternoon passed without any feeling. However, my part is only less than half completed, so it will not affect our work." Make progress." Li Jun was still a little worried, he didn't want to embarrass his second brother. Wang Yong also finished eating at this moment, wiped his mouth and said: "Li Jun, don't belittle yourself. I didn't believe you could operate a machine tool at first. I didn't expect you were also an expert. I just took a peek at you." ofThe accuracy of the software is absolutely unparalleled. It's true that I haven't been exposed to this new machine tool for as long as you. I'm probably the one who's most likely to delay the progress, but don't worry, I'll work hard. " Chen Er saw that the two of them were actually being humble here. He didn't know what to say. He could only add: "I feel so embarrassed when you all say this. Don't worry, I have seen you all just now. The progress has been made. Under normal circumstances, it will definitely be completed tomorrow morning. No need to rush or worry, all my parts will be finished tomorrow afternoon, so I can go test the gun tomorrow afternoon. " Li Jun said flatteringly: "Second brother, what you make are parts that are both small and require precision. Of course, you are not as fast as us. And you are the researcher of this pistol. Of course, you hope that the performance of the firearm can reach It's the highest, so it takes more effort than us to produce it. " Chen Er smiled helplessly. Li Jun was really not very good at flattering him. He didn't seem to feel happy at all. After sending Wang Yong away, Chen Er and Li Jun were ready to rest. Working hard for half a day today is a great test for both mental and physical strength, and it will continue tomorrow. The most important thing is that there is no guarantee of sufficient energy without a good night's sleep. There is no entertainment facility at all. If there is a mobile phone, tablet computer or the like in his hand, then Chen Er will probably not be able to go to bed until eleven or twelve o'clock at least. But in this era, those are just his own fantasies. Before six o'clock the next morning, Chen Er got up. What was rare was that Li Jun also got up. This was an unprecedented first time. The two looked at each other and started to go their separate ways. The rest of yesterday's work lasted until eleven o'clock at noon, when Li Jun stopped and looked at the parts in his hands and finally smiled with satisfaction. The hard work paid off and he finally noticed it. Wang Yong has also entered the finishing stage. To be honest, he didn't know when Wang Yong came. He couldn't even notice everything around him when he was working. By the time Wang Yong completed the final polishing, Li Jun was the one. He walked over and said, "Wang Yong, when did you come? Why don't I feel anything at all? "Wang Yong said with a smile: "Come on, I'm really embarrassed to compare with you. I thought it was very early to come here at 6:30, but I didn't expect that you were already busy when I came. Get up. If I had known better, I would have come here earlier. " Li Jun pulled him aside and said: "I woke up when I couldn't sleep in the morning. Besides, I felt a little uneasy when the work was half done. I guess it will take a while for the second brother. How about we get some bullets first? Then when we test the gun later, everyone will have to load a shuttle. " Wang Yong nodded and said: "No problem, we don't have anything else here. There are so many different types of bullets. Even if there are not thousands of rounds every time you test a gun, you can't test the performance of the gun. ah. "The two people were talking and walked outside. Wang Yong was very familiar with this place. Soon they arrived at the place where the ammunition was stored. When they heard that Wang Yong was going to try out a new gun, he gave them a hundred rounds without saying anything. Bullets. The two went to the cafeteria to have some simple lunch and then walked towards the research room. They were now looking forward to Chen Er completing the remaining parts as soon as possible. The development of a weapon seemed like a waste to them. Watching their children grow up step by step is definitely a special and unforgettable emotion. When they arrived at the research room, they were stunned. A brand-new pistol was already placed on the table. The only thing he did was to run to the table and pick up the gun. He looked around for a long time and tried it again. Not to mention, it was really easy. Chen Er looked at the side and said excitedly: "Second brother, you." Didn't you say you have to wait until the afternoon? How can this be done? " Chen Er took a deep breath and replied: "I didn't expect it to be so smooth. I finished it ahead of schedule this morning. I'm a little tired and I'm going to take a rest. You two can study it first. We'll go to the shooting range in the afternoon. Test gun. " Chen Er didn't bother to explain anymore at this time. He hurriedly returned to his room and fell on the bed. After about half an hour, Chen Er slowly woke up. I came over, but my head was still a little dizzy. This damn big military system wouldn't make me unconscious every time I upgraded. Fortunately, this time it only lasted half an hour, otherwise they would have thought it wrong if they found out. He was sick. After drinking a glass of water, Chen Er felt better and began to search for changes in the military industry system in his mind. "Congratulations on your successful upgrade to the second-level military industry." The first thing that came to his mind was this voice. , Chen Er had no idea about the levels of military industry, and he just wanted to know what he could make now.Looking at Chen Er, he was really stunned. Type 82-2 grenades, sniper rifles, anti-tank mines, special bullets, Type 56 light machine guns, and 60mm mortars. This second-level military industry is indeed much better than the first-level military industry. , Chen Er couldn't help but sigh in his heart, if he really reached level 80 or 90, wouldn't he be able to travel between the universe? It seems that the time machine is not a lie.
