ps: Thanks to Ro Seqiao and Bedwetter for their support, the third chapter has finally been coded! ! ! ! ??Please collect and recommend, please support by giving and subscribing! ! ! ! ! ! ! ¡ª¡ª ¡ª¡ª The three words "successful" seem so kind at this time. All the hard work and sweat of the past month seems to have disappeared, replaced by the joy of success. As for tomorrow's assembly and debugging, they are already proficient in it, and I believe that even Li Jun can complete it without fail. The three of them slept surprisingly well that night. Chen Er lay down on the bed before eight o'clock, and didn't get up until around seven o'clock the next morning. This was almost a full twelve hours of sleep. Chen Er rubbed his eyes and started to put on his clothes. This person is quite strange. He can sleep four or five hours a day at work without feeling tired, but after relaxing, he can sleep for eleven hours. It's a sore back. It seems that sleeping for a long time is not enough. In addition, the simple environment here, the wooden bed with almost nothing, it is strange that I am not tired after sleeping for a long time. Chen Er rubbed his lower back and opened the door. It seemed that he was the kind of overworked person who lived a life of sleeping until he woke up naturally. He might not have the chance in this life. He looked at Li Jun who still had the door closed in the distance. This guy is really a sleepy pig. As for counting money until your hands cramp, you can experience it. The simplest way is to just pick up a few pieces of money and count them non-stop. After a long time, your hands will cramp. But this is just a joke. Chen Er would not be stupid enough to do that. IQ is not used to heal injuries. After washing his face and brushing his teeth, it was eight o'clock in the morning. Li Jun's door finally opened, and Li Jun, who was fuming, walked out with a chicken coop on his head. If you think about this month's life, you will understand. Several people have been busy and have no time to pay attention to their own image. It is not surprising that chicken coop heads appear. If Chen Er doesn't tidy up in the morning. What's on top of his head is no better than Li Jun's chicken coop. Thinking about what happened yesterday when the three of them went to the cafeteria to eat, it was really interesting. Everyone looked at them like they were looking at monkeys in the zoo. The three people involved didn't know what to do. After returning home, Chen Er felt a little regretful after looking in the mirror. If he had known better, he would not have refused Murong Wan and Wen Jing's request for food. According to Chen Er's understanding, the three of them looked like standard killer figures, except that their hair could be dyed. Li Jun saw that Chen Er was distracted for some reason. He walked over and said, "Second brother, what are you thinking about? Looking at the way your eyes are shining, it couldn't be that this month has made you depressed." Chen Er didn't expect that this kid's thoughts were really dirty. Suddenly thinking of that aspect, Chen Er quickly punched Li Jun in the chest and said: "Hold on, you big-headed idiot. Wash your face and brush your teeth quickly. Children who look like you will be frightened and cry when they see you." Li Jun walked out as he walked out. As he walked, he said with a smile: "Second brother, we don't have children here. Just make fun of me. Besides, we are called alternative. You see, don't all foreigners have very long hair? And they also wear braids. Men have different aesthetics, so please bear with me, second brother. " Because Li Jun turned around and said to Chen Er while walking, his eyes did not look forward at all, and he almost bumped into Wen Jing and Murong Wan who were returning from lunch. . Murong Wan just smiled and walked past Li Jun, but Wen Jing was not that easy on Li Jun. When he passed by Li Jun, he secretly pinched Li Jun's arm. He also whispered: "I will give you a long memory. Next time, remember to look at the road. Don't look around." Naturally, the scene that happened could not escape Chen Er's eyes, which made Chen Er want to laugh, but he had to While holding it back, the whole person was in a state of leaning forward and back. Li Jun, on the other hand, was dumb and couldn't express his pain. He rubbed his arms and gave Chen Er a big eye roll. He really didn't have any solution for Wen Jing. This was probably how "tracheitis" slowly formed step by step. Wang Yong came right after breakfast. Although today¡¯s assembly and debugging task was light, it was also very important to the three of them. Things can never be done in a hurry. No matter what, the remaining work must be completed with 100% effort. This is the responsibility of Chen Er and the three of them, and of course it is also a promise of theirs. Thinking that today they can finally report to Director Zheng, the three of them are full of excitement. They quickly brought all kinds of parts, and the three people worked together to assemble them. The 60 mortar can be said to be quite simple. It can meet the requirements of individual weapons in terms of parts and operation. This This is also one of the reasons why Chen Er worked hard to develop it. In less than ten minutes, a very delicate-looking 60mm mortar was displayed in front of several people. small knotIt is difficult to associate it with a gun. Li Jun asked with confusion on his face: "Second brother, such a little guy can also count artillery. I don't think it is much better than a grenade." Chen Er shook his head, but he clearly knew that the 60 mortar The power of the cannon was just not mentioned when I lectured them. Now is a good time to take the opportunity to think about it, otherwise they will really think that they have researched and created a useless weapon, which would also dampen their enthusiasm. Chen Er sorted out his thoughts and said: "The 60 mortar uses anti-personnel grenades, artillery caliber: , shell muzzle velocity: 140\134 meters/second, maximum range: 1490/1470 meters. Shell firing speed: 30~35 rounds / minute, gun length: 610 mm, gun total weight: 200 meters, direction of fire: . Grenade total weight:, killing area: 15 meters. "Li Jun asked doubtfully: "Second brother, how do you deal with these. The data is so detailed, but we still haven't fired live ammunition." Chen Er smiled awkwardly, how could this kid react so quickly? He almost exposed his secret. He quickly added: "Actually, these are the results I have calculated these days. Of course, there may be some deviations during live ammunition, but I don't think the deviation is too big. There is no need to doubt the reliability of the data." Chen Er Since Having said this, Li Jun and Wang Yong stopped asking any more questions, and finally passed this level. Chen Er continued: "The key lies in the operation of this 60 mortar. This gun also has two different firing methods. One is for the gunner to face the target, untie the gun belt, open the legs, and align it. To set up the target gun, insert the hoe into the soil with both hands, kneel on one knee on the left side of the seat plate, adjust the leveling machine, adjust the bracket to a rough level, then fix the tightening handle, and insert the scope into the scope base The second gunner kneels on the right side of the seat plate, removes the muzzle cap, raises the height machine, and cooperates with the first gunner to adjust the pursuit gun to center the height bubble and tilt bubble on the optical sight, and then install the rear sight as needed. , direction marking, charging, etc., and finally shake the height machine and direction machine to align the crosshair with the target, and then launch. When loading, the second gunner takes the shell from the third gunner and loads the shell upright into the muzzle, so that the shell can be fired. Slide down smoothly and hit the firing pin to fire. Of course, the second type is simple shooting, which is to use only the barrel to hold the gun. This shooting method is generally used to shoot targets within 200m, or to fire under special circumstances. Target, take a half-step forward with your left foot, and kneel down with your right knee to the right, with your right thigh at about 90¡ã to the direction of the shot, your buttocks sitting on your right heel, and your left calf slightly vertical with both hands raised. Press the cannon pestle into the ground at a suitable position on the right side of the left foot. The gun body is about 10cm away from the left calf. Raise or lower the shooting angle of the gun body with the left hand holding the gun hoop and the left forearm firmly against the inner side of the left thigh. Load the shell into the muzzle, aim your right eye at the target through the white mark on the gun body and the center of the fuze. At the moment when you have good aim, hold your breath and quickly release the shell to fire. " Li Jun and Wang listened to Chen Er's explanation. Yong was also speechless. He didn't expect that this cannon could be used like this. Today he had gained a lot of experience. Chen Er saw that these two guys were finally convinced, and he breathed a sigh of relief. Li Jun suddenly took out a baggage, handed it to Chen Er's hand and said, "Second brother, this is for you." Chen Er took it in confusion and asked, "Li Jun, what is this?" Li Jun Jun smiled mysteriously and said: "Second brother, you will know if you open it and take a look. I promise this is a good thing." Suspicious, General Chen Er opened the baggage, and it turned out to be a large piece of red silk cloth. Chen Er was full of doubts. He asked with a puzzled face: "Li Jun, where did this come from? What's the use of giving this to me? Why do I think this looks like a quilt cover? We don't make quilts, so what did you do with it?" " Li Jun said with a smile: "Second brother, you just don't understand. Haven't you seen that some store opening celebrations require a red cloth or something? You should understand, right? I brought it from home, and my mother specially gave it to me. " Chen Er also understood at this moment that this guy Qing had to go through a process similar to a ribbon-cutting ceremony for this cannon. This bright red quilt was probably bought by Li Jun's mother to make his wedding quilt. This boy was really willing to give it out, so he must accept it. Now that Li Jun had made a decision, Chen Er simply put his quilt over the 60 mortar and said, "That's all for the head office. Let Director Zheng Guoqiang come over to uncover it in person tomorrow. We can also think of doing this for this 60 mortar." It¡¯s time to fire the cannon and cut the ribbon.¡± Li Jun said with a satisfied smile: ¡°Second brother, you can still speak. Yes, you can cut the ribbon, but I can¡¯t cut my quilt, otherwise my mother will scold me to death. "Li Jun's words caused a burst of laughter from several people, and the 60 mortar was finally successfully placed in the research room. (To be continued)
