I kneel down to you gentlemen, I don¡¯t want my buns to be poked so that the stuffing comes out! ! ! Cry, cry, cry, cry, cry, cry, cry, cry! ! ! ! ! ! ! ! ! ! ¡ª¡ª ¡ª¡ª Besides, Chen Er was looking at the thick pile of blank drawings on the table. He just started to make his own plans. Although there are already hundreds of drawings here, in Chen Er's opinion, they are just the tip of the iceberg. Thinking about how much work he had to accomplish in these twenty days, he couldn't help but admire himself. For the average person, seeing so many drawings, they would definitely not know where to start. After sorting out his thoughts, Chen Er spread out a drawing and started drawing it with a pen. He copied it exactly according to the drawing prototype in the large military industry system, and soon a dozen drawings were completed. Perhaps because these drawings were relatively simple, Chen Er didn't even feel the slightest bit tired. If he had maintained this speed, he might have been able to finish it ahead of schedule in less than twenty days. During this work, Chen Er¡¯s energy was completely focused on the drawings. As he drew things on the blank drawings, time passed quietly without realizing it. Chen Er stopped when he felt a little tired in his eyes. Concentrating for a long time is also a great test for the eyes. After rubbing his sore eyes, Chen Ercai raised his head and glanced at the time. He looked stupid at this sight. It's actually seven o'clock in the evening. Looking at the twenty or so completed drawings, Chen Er was also relieved. This is a job that relies on time accumulation. How can we complete these tasks without spending so much time? Fortunately, today went smoothly, and there were no mistakes in the painting process. At this time, Chen Er¡¯s stomach growled unsatisfactorily, which obviously made him want to eat quickly. Chen Er stood up, stretched and walked out of the house. By this time, Li Jun and the others must have finished their meal, hoping that their portion of the meal would still be warm. After opening the door and walking out of the house, he saw three people sitting and chatting in the yard. When Li Jun saw Chen Er finally coming out, he immediately said with a smile on his face: "Second brother. You have finally come out. Murong Wan has already come out." She has heated up your food twice. If you don't come out, she will heat it up for you again. " Chen Er looked at Murong Wan who was sitting aside and cast a grateful and touched look. After all, it was his own. Wife, you care about yourself so much at all times. Chen Er looked at the lunch box on the table, picked it up without hesitation and started cleaning. Although sitting in the room and drawing pictures seemed like a kind of mental work, it was actually a great test of physical strength. Li Jun and the three of them also have a deep understanding of this. This is just like when you go to school. It seems like you just sit in the classroom for half a day every day. In fact, you may have to face several teachers in half a day. Different subjects need to be constantly switched in the mind, and memory and digestion are also required. These are definitely not just mental. The scientific community has also proven it. In fact, 90% of the energy in food is used to maintain human life, and only the 10% is consumed by labor. ?This is conceivable. Even if you do nothing, you still have to eat. Of course, some extreme conditions are excluded. As for where the physiological limits of human beings are, I am afraid it is also a constant topic that all scientists have been studying. After Chen Er finished eating all the food, Li Jun dared to speak: "Second brother, I just saw you carrying a stack of blank drawings into the house. Did you use so many?" Chen Er said this I really don¡¯t know how to explain it. It seems that Li Jun still doesn¡¯t have a systematic concept of this heavy artillery. After thinking about it, Chen Er had to say: "Let me tell you this, this is like the difference between bicycles and cars. Think about bicycles." Originally, the structure is simple and there are only dozens or hundreds of parts at most, so the number of drawings required is naturally less. But the car is different. There are tens of thousands or even hundreds of thousands of parts. If all the drawings are counted, it may be. Such a house cannot fit in. Although this heavy artillery is not as complex as a car, the number of drawings is still quite large." Hearing Chen Er's metaphor, the three of them opened their mouths in shock. Li Jun was the first to react. Then he continued: "Second brother, how many drawings do you estimate we need?" Chen Er was also stunned at this moment. Although he had read all the drawings of the 122mm howitzer, he really didn't calculate how many drawings were needed. , but it looks like there are thousands of them at least. But since Li Jun asked like this now, it would be a bad idea not to answer. Chen Er could only think about it and said: "SpeciallyI can't say how many there are at the moment. Anyway, I estimate there must be thousands at least. " Then Chen Er added: "Of course, this doesn't count the mistakes I may make, so Li Jun, you can bring me two stacks of drawings tomorrow and let's talk about it after you use them. Blueprints cannot be saved now. Even one missing piece may affect the final development of the cannon. "Li Jun nodded after hearing this. Since he couldn't help with the drawings, he could only work as a coolie. Besides, the two piles of drawings were not very heavy. He chatted a few words with Li Jun and Chen Er. It was time to go back to the room. After eating and drinking, it was natural to burn the midnight oil again. Chen Er worked until almost eleven o'clock that night before he stopped. I'm afraid Li Jun and the others had already gone to bed. Er felt that it was quite quiet outside, with only a few insects chirping. After sorting out the drawings he had drawn today, Chen Erlian took off his clothes and went to sleep on the kang without even thinking about washing. Because of the high level of concentration, people are naturally very tired. As soon as they relaxed on the kang, Chen Er fell asleep within five minutes. It can be said that he slept very sweetly until dawn the next day. Only then did Chen Er open his eyes. After getting up, Chen Er didn't even bother to fold the quilt. The first thing he did was to go straight to the table. The day's plan is always the clearest in the morning. Having time to draw a few more drawings, Chen Er felt really sorry for waking up so early. An hour passed quickly, and five more complete drawings were obtained. Chen Er smiled and put these five drawings away. On the other side of the table. In order to distinguish the different parts of the drawing, Chen Er marked it in detail yesterday. From a, b, c, d to 1, 2, 3, 4, it can be said that all the parts under one letter are clearly marked. When the drawings are gathered together, they become a complete component. This way, even if the drawings are confused or lost later, you will not be afraid at all. At least you will know which one is missing and Chen Er is sorting it out. At that time, there was a knock on the door. Chen Eryi guessed that it was probably Li Jun. He had asked him to deliver the drawings yesterday, and no one else would bother him. As expected, the person standing outside was the one who opened the door. Li Jun, and he was still carrying two large stacks of thick drawings. Chen Er quickly took them and put them on the floor in the room. Then he looked at Li Jun and said, "I guess it's you. But I didn't expect you to come so early. Li Jun looked at the drawings completed by Chen Er on the table and said, "Second brother, you can draw very fast." Will it last twenty days at this rate? " After Chen Er sat down, he smiled slightly and said: "The early ones are just some simple drawings, so the speed must be very fast. You can also take a look. Basically, even if you draw these, you will be very fast. Later, as the drawings become more and more refined, the speed will definitely slow down. "After Chen Er said that, Li Jun also sat on the side and picked up the finished drawing and looked at it. Although he still understood the data and structure on the drawing. But the specific purpose of this part is probably only the second brother himself. Got it. After looking at Li Jun, he put the drawings on the table in the original order. Li Jun had already resisted the second brother's ideas. As for what the final object of these drawings was. This kind of thing can only be known after it is made. At this time, he slapped his forehead and said: "Look at my memory, Wen Jing asked me to go to dinner together, the two of them have already gone to the cafeteria. , I believe you will be back soon, and eating here will save you from delaying your work. ¡± Chen Er was still very touched by the attentiveness of the two girls. It felt like he was back to the time of the Third Small Arms Research Institute. At that time, he basically had food and accommodation in the house, except for going to the toilet. But he devoted himself to his work. Chen Er shook his head and followed Li Jun out of the house. Within two minutes of sitting down, Murong Wan and Wen Jing came back with their breakfast. Li Jun could do it now. It is said that it is very busy. I have to teach more than ten college students in the morning and teach them some practical operations in the afternoon. It can be said that the day is quite fulfilling. After breakfast, I go off again. After finishing their work, Chen Er looked at Li Jun and said: "Now they should have mastered part of the basics. You can increase the capacity of the course for them appropriately. After all, our time is limited, so you should teach them as much as possible in these twenty days. After twenty days, it may be time for them to show their strength. ¡± In fact, Li Jun has had this idea for a long time. In this era, there is no such thing as the phenomenon of teaching apprentices and starving the master to death. This stage is the primary stage of the development of China¡¯s socialism. It can be said that all aspects have improved. There is an urgent need for a large number of talents, especially in the national defense and military areas, Li Jun.Being able to bring out more than a dozen good players at once is not only a blessing for Southeast Heavy Industry, but also a blessing for the whole of China. As soon as Li Jun left, Chen Er locked himself in the room again. Today was the second day, and he still maintained the same energy as yesterday. He really wished that he could have a few more arms all of a sudden, like that It's just that I can draw faster. Perhaps because today's drawings were more complicated, Chen Er inevitably drew a few useless drawings, but this was considered a normal phenomenon and did not affect his enthusiasm at all. Although Murong Wan was sitting in the courtyard a little bored at this time, all she could think about was Chen Er. Looking at the closed door, she wanted to go in and give Chen Er a shoulder massage. . But when he thought that doing so might disturb Chen Er's train of thought, he finally had to give up the idea. Girls' minds are inherently complicated, and Murong Wan perfectly reflected this. Seeing Murong Wan's frowning expression, Wen Jing quickly comforted her and said, "Wan'er, don't worry so much. Chen Er is not a child anymore. I think he must have his own plans in mind. As long as you Just make sure that he can eat hot meals every day, and more won't help." Wen Jing actually wanted to help Li Jun, but after thinking about it, she really didn't know how to do it. It seemed like this. It looks like a vase. But there's nothing wrong with making vases. For women, it's also a good choice to take care of your husband and raise your children. After listening to Wen Jing's persuasion, Murong Wan's mood improved a little bit, but at this moment she suddenly had a bold idea. She wanted to give Chen Er a child. Maybe she would be more confident when she became a mother. It feels like home. Besides, Chen Er and Chen Er had been married for almost a year, and they had done a lot of things. Why was her stomach so unsatisfactory? Murong Wan couldn't help but feel a little annoyed. (To be continued, please search Piaotian Literature. The novels will be better and updated faster!
