The next morning, that is, just after six o'clock, Li Jun was woken up by the noisy sound of machine tools outside, put on his clothes in a daze, pushed open the door and came to the outside research room, and saw that Chen Er didn't know what he was busy working there, and said while rubbing his eyes: "Second brother, what are you doing this morning, I see that you are really energetic, you don't sleep, even I can't sleep." ”

Chen Er stopped what he was doing and said, "How can you do this good youth after you have slept in your youth, you see that even Murong Wan and Wen Jing are up at this time, that is, your kid is still sleeping, I won't tell you, I'm going to continue to be busy." After saying that, Chen Er started the machine tool and got busy again, Li Jun looked indifferent, he couldn't sleep, he just sat next to him, observing what Chen Er was doing.

After about half an hour, Chen Er finally stopped the machine and said to Li Jun, "Show you a good thing, and then." A round thing was thrown towards Li Jun, and Li Jun took it in his hand out of instinct. This look immediately shocked a cold sweat, hurriedly threw a long distance, and lay on the ground, and it took a long time before Chen Er got up in laughter.

It turned out that what Chen Er threw over was the shell of a ready-made Type 82-2 grenade, Li Jun said with some anger: "Second brother, I was scared to death just now, let's not play like this, you don't know what it feels like I received that thing just now, it's just a soul flying out of the sky." Chen Er walked over and picked up the shell and said, "Now you kid is not sleepy, I don't have a charge, I didn't expect you to be so timid." ”

Li Jun hurriedly quibbled: "Second brother, this is really not a matter of guts, whoever sees such a round iron thing falling into his hand, it is definitely fake not to be afraid." Besides, this is still thrown from your hand, who knows if it is an advanced weapon that you know, I don't want to do anything real. Li Jun is not sleepy at all now, and he is even a little afraid.

Chen Er said with a smile: "I really guessed it right by your kid, this is an unfinished grenade, how about it, it looks good." Li Jun took the shell from Chen Er's hand again, looked at it for a long time, and said: "It looks similar to the Japanese Type 97 grenade, and it is quite comfortable to hold in your hand." And I think yours seems to be a lot lighter, but it doesn't have a charge, a fuse, etc., so it looks pretty good. ”

Chen Er couldn't help but smile and said, "I didn't expect that your kid is still very knowledgeable, and you also have research on grenades." Li Jun said proudly: "Hehe, now you are really right, second brother, when we were in the 5o1 arsenal before, I naturally couldn't be idle when you were engaged in research." I have personally thrown this Type 97 grenade a few times, and the power is indeed much stronger than the wooden-handled grenade in our country, but the disadvantage is that the delay is not very stable, and sometimes it explodes after seven or eight seconds. I don't think it's a human, even a turtle can dodge. ”

"And the quality has reached a pound smaller, and a soldier can carry seven or eight at most, which is the limit, but it is still a lot lighter than a wooden-handled grenade." Listening to Li Jun's eloquent words, Chen Er couldn't help but nodded, what Li Jun said was to the point, he really had nothing to add, and now the troops are still equipped with wooden-handled grenades, and it is indeed time to improve.

Chen Er continued: "Don't underestimate this guy I made, although it looks similar to the Japanese Type 97 grenade, but you also saw that my grenade uses an oval shell, which can not only increase the space inside the shell, but also greatly save raw materials, and greatly reduce the quality." I've also made improvements to the refilled shrapnel, but this is kept secret for now. ”

Li Jun's various novel ideas for Chen Er have reached the level of not strange, in his opinion, there seems to be nothing impossible for the second brother, if it is put in the twenty-first century, it will be blind worship, but in that era, it can be regarded as a normal thing.

Li Jun saw that he couldn't help his second brother, so he simply went back to the house to read a book, and said that he would live to learn all the time, this sentence is more applicable to their industry, and it will definitely not work if they don't study for a day. Because if you want to successfully develop a weapon, drawing is the foundation, machine tool operation must be able to know, the mechanical principles of firearms must also be understood, and the accuracy of bullets and the battlefield practicality of the whole gun must be considered, which is definitely a complex and huge body of knowledge. If you want to have your own achievements in this area, if you are not a talent like Chen Er, you have to pay ten or even a hundred times the sweat of ordinary people to have a little achievement.

Seeing Li Jun leaving, Chen Er picked up the shell and processed it again, and with the continuous sound of the machine tool, soon the Type 82-2 grenade shell was finally officially completed. Chen Er glanced at the time and it was already more than eight o'clock, thinking that he didn't care about eating breakfast, he was enough, put the shell, and Chen Er started to make other parts.

The delay fuze is composed of four parts: the fuze body, the ignition mechanism, the initiation device and the safety mechanism, which is the main body of a grenade, and whether it can succeed depends on the accuracy of the delay fuze system. The reason why Japan's Type 97 grenade exploded by mistake was that there was a problem with the time-delay fuse, and besides, the fuse was the greatest guarantee for the safety of the grenade, and Chen Er did not dare to slack off in the slightest.

Although he has a large military industrial system, after all, it is only the various drawings and development process of the weapons that have been provided to him, and if he wants to restore these weapons in his mind, he still has to rely on his own hands. The development of weapons is naturally accompanied by all kinds of dangers, Chen Er does not dare to be sloppy, a morning of time has passed suddenly, Chen Er is still busy in a nervous and orderly manner.

More than an hour passed, Chen Er finally exhaled deeply, the fuse part was finally completed, now only need to complete the gunpowder and shrapnel filling inside the shell, and the grenade with the fuse is officially completed. After resting for a while and drinking a little water by the way, Chen Er really sweated a lot after a busy morning, although this was in the belly of the mountain, but for a person with a high degree of mental concentration, he was still sweating in the morning, and Chen Er was a true portrayal of this state at this time.

The process of filling gunpowder and shrapnel is not so complicated, and with the last step Chen Er carefully pressed the fuse into the body of the projectile, an 82-2 grenade really appeared in Chen Er's hand. Looking at this exquisite "work of art" in his hand, Chen Er couldn't help but smile, this is definitely just a "work of art" for them, but on the battlefield, this is a killing weapon for harvesting human lives.

It is said that science is not guilty, and there is nothing wrong with those who study weapons, but once weapons are used on the battlefield, it will definitely bring bloodshed and killing, but you can blame those who developed these weapons. The answer is definitely no, their original intention may be just to further human civilization, but the result is often not something that can be controlled by one person or a group of people.

When Li Jun came out, he was looking at Chen Er holding a prepared grenade, he walked over and patted Chen Er's shoulder and said, "Second brother, what do you think, you are so engrossed, I see that your eyes are straight, and I always say that I am cranky, I don't think you are far behind." Chen Er was slapped by Li Jun and immediately came back to his senses, how did he think of that just now, he is just a military worker, don't think about the philosopher's business.

Chen Er shook his head and said, "You kid don't be so dirty, okay, I'm different from you." He shook the grenade in his hand and said, "Let's go, let's go to the shooting range and test its power, it is guaranteed to scare you." ”

Li Jun said disapprerovingly: "Just go, isn't it just a grenade, is it possible that the power will be greater than the cannonball, I want to take a good look." "The two of them just walked out not far before they ran into Wang Yong, he was going to find Chen Er and them early in the morning, but suddenly the master arranged a little task for himself, this is not just completed and ready to pass, who knows that here is in advance.

Knowing that Chen Er had come up with another grenade, Wang Yong regretted it even more at this time, he had already known that he had let others do what the master had explained to him, which was another great opportunity for him to learn. But it wasn't too late, and Wang Yong was also walking towards the shooting range with them.

There were dummies made of wood on the shooting range, in order to test the power of guns and grenades, Chen Er looked at Li Jun and Wang Yong and said, "You come or I come." Of course, Li Jun volunteered to take the grenade and said: "Of course I'm here, you all stand back a little, it's better to hide in the bunker over there, I don't guarantee that I can throw it into that position." ”

When Chen Er and Wang Yong both entered the bunker, Li Jun pulled out the pull tab of the grenade, pressed it and threw it hard, and the whole person quickly hid in the bunker next to him. The grenade made a perfect curve in the air and fell to the ground about 30 meters away, and about a second or two later, there was an explosion of "boom".

After more than ten seconds, when the smoke and dust cleared, Chen Er and the three of them walked out of the bunker, Li Jun shook the soil on his body and said: "Second brother, don't you say that this grenade is quite loud, but I don't know how powerful it is?" The three of them trotted to the site of the explosion, and a deep pit had been blown out of the ground, and the wooden dummy next to it had also been overturned.

Li Jun casually brought over a wooden dummy, looked at it and said: "Second brother, what are you putting in this grenade, you see that this dummy has been blown up beyond recognition, and the whole body is densely covered with small holes, if this is replaced by a real person, it must be a sieve." ”
