Thank you brothers for your monthly support, Baozi thanks you again! ! ! ! ! ¡ª¡ª ¡ª¡ª After moving his muscles and bones, Chen Er felt that there was such a feeling all over his body. A sense of comfort. The biggest advantage of this era is that the air is fresh and there is less pollution. During this period, China was in a stage of development of basic industry. There were only a handful of heavy industry plants under construction in the country. Coupled with the pitiful number of cars, it was impossible to cause air pollution, let alone cause irritation. of smog. Within ten minutes, Wen Jing and Murong Wan came back happily with their lunch boxes. Li Jun and Chen Er were no longer polite, took the lunch boxes and started eating. Although breakfast was just some gruel and pickles, Chen Er still ate it with gusto, which was enough for him. After breakfast, Chen Er said to Li Jun: "Why hasn't Wang Yong come here at this time? Didn't he come here very early before?" Li Jun waved his hand and said: "Second brother, you are mine. Dear second brother, do you really think that everyone else is a workaholic like you? I guess Wang Yong won't come today. He also wants you to come back and have a good rest, otherwise he would have come here yesterday. " Chen Er could only nodded, but he didn't quite agree with Li Jun's words. Thinking about it, it seems that I have never done anything else except researching some weapons. Moreover, the job is transferred here and there, and I spend a lot of time on the road. To be honest, I can't be considered a workaholic. Thinking about the office workers in the 21st century who just work overtime until ninety o'clock in the evening, this is really a trivial matter for me. After waiting for a while, Wang Yong still didn¡¯t come. It seemed that Li Jun was right. Chen Er originally wanted to take this opportunity to rest for a while. But the sound of machine tools that followed made his thoughts disappear. The sound of machine tools may be a moving piece of music when you are working, but once you are free, the noise is not something that ordinary people can bear, and it is a great test to people's spirit and willpower. So generally, those masters who often operate machine tools will prepare two cotton plugs and put them into their ears when working to reduce the impact of sound on future hearing. Chen Er seemed to be used to this kind of sound. He came to Li Jun who was polishing some parts and asked loudly amidst the roar of the machine: "Li Jun. Wang Yong is not here today. Are you still here alone?" What are you busy with? There seems to be something wrong with your operation method. " Li Jun stopped the machine and said, "Second brother, this is a polishing method that Wang Yong and I have developed. It is different from our previous methods. The effect has improved a lot. If you don¡¯t believe me, you can give it a try.¡± Chen Er took the parts and tried them on the machine tool according to Li Jun¡¯s instructions. It turned out to be much easier to operate. I didn¡¯t expect this kid to have this ability. Talent, it seems that the saying that you live and learn is true at all. After doing it some more, Chen Er used an excuse to leave. Now he suddenly had an idea. Anyway, he was idle now, so he might as well find a way to upgrade his large military industry system. If you want to build aircraft and cannons, it will definitely not work without hard work. Maybe when its military level reaches six or seven, and aircraft and artillery are no longer a problem, then China will truly have its own national defense strength. Chen Er went straight back to his room, lay on the bed and began to meditate. The large military system in his mind was also turned on, and items of content and various data were displayed in front of his eyes like a movie. Flashing continuously. When he dodged the anti-tank mine, Chen Er suddenly opened his eyes and it was it. Anti-tank mines are definitely a good thing, and they happen to be in my secondary military industry catalog. Chen Er didn¡¯t even think about choosing China¡¯s Type 72 anti-tank mine. Armored vehicles and tanks of this era did not have composite armor, let alone a special V-shaped site. An anti-tank mine would be an absolute nightmare for such tanks and armored vehicles. Having made up his mind, Chen Er sat at the table and started drawing drawings. Since anti-tank mines are aimed at large vehicles, they basically use pressure-detonating devices. That is, once the vehicle reaches the anti-tank mine, superior. This will activate the mine's detonating device, destroying the vehicle. Chen Er doesn't want to make too many changes now. This press-type detonation device is more convenient to use now. Anti-tank mines are different from general anti-infantry mines because they require stronger explosive power. Therefore, there are more charges, and the volume is inevitably much larger. In terms of production, there is no doubt thatIt also adds some difficulty. The drawings were also more complicated than ordinary mines. Chen Er concentrated on drawing on each drawing, and time passed unconsciously. It wasn't until someone knocked on the door that Chen Ercai put down his pen and rubbed his eyes. When he opened the door, he saw it was Murong Wan. Chen Er smiled and said, "What do you want from me?" Murong Wan pointed at Li Jun and Wen Jing who were eating and said, "Aren't you hungry? We thought you were there at noon. I didn¡¯t bother you while you were sleeping. It¡¯s already six o¡¯clock in the afternoon, and you can sleep well enough. Fortunately, I¡¯ve made a lot of food, so go eat it quickly, or you¡¯ll be cold soon.¡± After that, Murong Wan said. He left with a blushing face. Chen Er stayed there for more than ten seconds before looking up at his watch. Sure enough, it was six o'clock in the afternoon. Doesn't that mean that he spent an hour painting this drawing? Why did the time pass so quickly? At this time, Chen Er's stomach inevitably heard the sound of protest. Chen Er didn't care about thinking so much. He walked over and picked up the lunch box and started sweeping. This time, his speed was much faster than Li Jun. . After eating, Chen Er didn¡¯t say anything but went back to the house. His mind was now full of drawings of anti-tank mines. If he didn¡¯t finish the drawing today, he probably wouldn¡¯t be able to sleep. Seeing how abnormal Chen Er was today, Li Jun said doubtfully: "Second brother, it's because he has a fever. Otherwise, where did he get so much sleep? I have to go and have a look." Before Li Jun could stand up, he was Wen Jing grabbed him. He didn't understand what Wen Jing meant. Wen Jing seemed to have noticed Li Jun's doubts, and she opened her mouth and said, "Sit down honestly. Have you ever seen a person with a fever be as energetic as Chen Er? I guess Chen Er must be thinking about something." , It¡¯s a good thing that you are still his brother, you don¡¯t understand this thing.¡± Li Jun thought at this time, the second brother is always mysterious every time he comes out with a new weapon, maybe the second brother is secretive. I am currently drawing pictures in the house. If he entered, he would have disturbed his second brother's thoughts. That would be a huge sin. Thinking of this, Li Jun quickly gave Wen Jing a thumbs up and said with admiration: "You're right. I was reckless." He looked like he was prostrating himself under Wen Jing's pomegranate skirt. Murong Wan couldn't stand it at this time. These two people were swaying in front of him, and they really regarded him as nothing. Murong Wan took Wen Jing's hand and said as she walked: "Li Jun, we've finished eating. You can eat slowly." But Wen Jing clearly had a lot of food in his lunch box. Said: "Wan'er, I haven't finished eating yet. We can't waste food. Please let me go quickly." Murong Wan said in Wen Jing's ear with a hint of teasing: "Wen Jing, then go and talk to Li Jun Let's eat together, I will never stop you." Wen Jing was too stupid not to understand the meaning of Murong Wan's words at this time. She also laughed and said in Murong Wan's ear: "Wan'er, you. Are you jealous? We are good sisters. You have found a good home, so naturally I can¡¯t fall behind.¡± The two of them joked with each other and went back to their houses. Li Jun sat there blankly alone. He thought that he didn't seem to have offended Murong Wan during this period. Why did she seem to have deliberately targeted him just now? The woman's mind was really strange. ¡°Besides, Chen Er had no idea what was happening outside. He continued to draw when he returned to the house. He was busy until about ten o¡¯clock in the evening when he finally finished it. Chen Er looked at the thick stack of drawings in front of him. He also breathed a sigh of relief slowly. Drawing seems to be a physical job, and my back hurts at the end of the day, especially my two arms, which feel like they are no longer my own. Chen Er didn't care about tidying up at this time. He fell on the bed and began to fall asleep. Concentrating on this day would be a challenge for him, if it weren't for the strong physical strength and energy of young people. Most people can no longer bear it. Within five minutes, Chen Er's snoring could be heard. Of course, Chen Er's facial expressions were also very rich. It seemed that he was having a secret tryst with some beautiful woman in his dream. ¡°Maybe it was because Chen Er was too anxious when he entered the house after dinner, but the two doors were not closed so tightly. He didn't have the habit of locking the door when sleeping here. Through this crack in the door, he could see Chen Er sleeping on the bed. By coincidence, Murong Wan happened to come back from washing up at this time. Out of instinct, she glanced towards Chen Er's room, and she discovered the unclosed door. Murong Wan hesitated for a moment, then walked over and helped Chen Er close it from the outside. After all, it was easy to catch a cold if the door was left open at night, and she didn't want Chen Er to get sick. As soon as Murong Wan turned around, she met Li Jun who came out to use the toilet. This was all obvious to Li Jun. Murong Wan originally wanted to explain, but when she saw Li Jun¡¯s expression of ¡°I understand¡±With a look in his eyes, he simply stopped talking and hurried back to his house alone. She originally thought that Li Jun really understood what she meant, but Li Jun was still thinking about it while going to the toilet. The second brother was really unreasonable. He always did this secretly at night. No wonder he slept during the day. After such a long time, it turned out that I was recharging my energy. This time, it can be said that yellow mud fell into the crotch, it was either shit or shit. The person involved, Chen Er, was very unjust. He was still a virgin. Who are you going to talk to about this matter? You can only digest this bitterness slowly by yourself. (To be continued.
