(Thanks to Antonye, Da Wuming, Rongcheng, Za Wangchen, Zhao Changsheng, Chen Yuan's rewards and red envelopes, Miao Miao is busy working at home for the New Year, and I will go to the code word first when I have a little time at night, don't be surprised if I don't sign in to the brothers...... ）

The girl pouted, although she was still a little angry, but she didn't say anything too heavy, and a sweet feeling suddenly rose in her heart, which was wonderful.

Lao Jing stood up against the wall, shook his shoulders a few times, and the bone joints "click" rang non-stop.

After the wind chimes were ashamed, they began to worry about whether they had really exerted too much force just now, and the sound was quite scary.

But the girl's reserve really didn't allow her to go over immediately to ask for warmth, but her face was red, and her little hands couldn't stop pinching and rubbing the corners of her clothes.

Although Jing Jun still felt a little pain in his back, he was also full of sweetness when he looked at his beloved lovely child's shyness.

The heart is still good to accept it, the girl's family is easy to be shy, and this matter has to be done slowly.

Bent down to pick up the table and chair, covered his mouth and coughed lightly, and said, "Uh, Lingling, that, come, sit! Brother still has something to discuss with you......"

Feng Chime's face was still crimson, he didn't dare to look at Jing Jun, his head turned away, and he said: "Hmph! You have something to solve by yourself! What does it have to do with me!"

That being said, without moving the body, typical duplicity.

Lao Jing smiled and said, "That...... It's not good for me, but I really need your help, come, sit here first. ”

The girl squirmed for a long time, and finally sat next to Jing Jun, but now she looks very restrained, and her pretty face is more beautiful than before.

Lao Jing's heart was beating loudly, and he secretly exclaimed, "I can't stand it!"

But his years of sniper mentality training played a very important role at this time, and he forced himself to suppress his inner thoughts, and said: "That's the case, I think it's time for us to start trying to develop machine guns!"

"Oh?"

Feng Chime's eyes lit up when he heard this, and he was relieved from the embarrassment just now, and said hurriedly: "Okay, okay, isn't it that the dog military master started to itch in his heart when he saw you and Hatian kill so many people with machine guns last night?"

The girl was indeed smart, and guessed the dog's plan so quickly.

"Hehe, in fact, it's not just the military advisor who has such thoughts, I'm also thinking about whether to get a machine gun these days, after all, the situation in Donghai Town is getting more and more severe now, not to mention that I've been thinking about whether I will become a war criminal and so on, these useless worries, looking ahead, are not as simple and decisive as you and Yanran......"

It was the first time that Jing Jun had spoken his true thoughts on the development of firearms in this world in front of the wind chimes, even though the two had already worked together to develop a giant rifle gun that worked well.

The wind chime shook his head slightly, and said softly: "Well, I can understand your thoughts, big brother, but I believe you can also see that we must do something to deter those forces that are about to move!"

"Yes, now that the eldest brother has figured it out, let's start developing our killer feature from today!"

"Well, which gun do you think we should use?"

Wind Chime's eyes lit up as soon as he mentioned mechanical research, making it difficult to overlap it with the shy girl just now.

Lao Jing no longer had the intention of joking at this time, and after thinking about it seriously for a while, he said: "Speaking of machine guns, this is different from rifle guns, the mechanical principle is much more complicated, and it is difficult for me to determine which gun type to refer to for a while. ”

"Cut, what's this, you're a military captain, and you've been a firearms expert for many years, so it's okay to take out the most advanced one and use it for transformation. ”

Wind Chime was dismissive of Lao Jing's concerns.

"Hehe, how can it be so simple, the principle of modern machine guns is basically Makqin's invention of using the gas produced by the combustion of gunpowder when the bullet is fired to make the bolt complete a series of actions such as unlocking, unshelling, feeding, and re-locking, realizing the automatic continuous shooting of the single-barreled gun, and reducing the recoil ...... of the gun."

"Yes, I've heard of this principle, modern machine guns have been doing this for more than a hundred years, and it's very advanced technology, so let's just follow it?"

Before Jing Jun finished speaking, Feng Chime interrupted, she still didn't understand what her eldest brother was worried about.

"Uh......"

Lao Jing's tone was stagnant, his thinking was a little messy, he looked at the girl with a wrinkled small nose, and said softly: "Hehe, the principle is very advanced, but you may have forgotten that what kind of chemical powder is used in us, and what kind of fire, how much cartridge is loaded in the cartridge case, and how much recoil is probably generated, I can basically estimate it, so if we are still on the earth, the principle of the Maxim machine gun should be the best choice." ”

Hearing this, Wind Chime's expression changed slightly, and she seemed to realize what the problem was.

"However, our current cartridge casings are filled with flamingos, and the power of this kind of thing after explosion is not small, but I have found that the recoil generated by it is really not large in the process of using the large-caliber rifle gun for more than a month, so I am worried that the maximum power of the machine gun cannot be exerted under the small recoil. ”

"Oh...... That's a problem......"

The wind chimes puffed up their pink cheeks and tried to find a solution.

"Another very important aspect is the cooling of the barrel, I don't really like the bulky water-filled cooling sleeve, after all, there is still a big gap between the strength of the barrel made by hand and the barrel produced under modern technology. ”

Jing Jun raised another question, indeed, the machine gun can provide continuous fire support, but then the barrel will be seriously heated, even red, not to mention the durability will be reduced, and the life of the machine gunner will be endangered, so it has to be carefully considered.

He also mentioned that the solution to the problem of overheating the barrel in the modern army is usually to replace the barrel, but this method is honestly very dangerous in the rapidly changing battlefield.

Feng Chimexiu frowned, although she was very smart, she was not an expert in mechanical engineering after all, and she couldn't think of a good way to solve these problems for a while.

Jing Jun said at this time: "Actually, I have also considered another gun type, but it may be more cumbersome, and the mobility will inevitably be insufficient. ”

Feng Chime's eyes rolled, and he said coquettishly: "Big brother, just say it when you think of it, even if it's bulky, it won't be difficult for those guys who are full of muscles!"

"Ahem, uh, it's actually a Gatling Gun!"

Lao Jing sighed secretly, it is true, it is cumbersome and has to be compared to anyone, and the minotaur who can each carry a sledgehammer of several hundred catties may be considered bulky when he reaches the level of a demon slayer knife.

When the wind chimes heard this, their eyes lit up, and they exclaimed, "Yes, why am I so stupid, isn't Gatling very good!"

Thinking of the excitement, the beautiful girl grabbed Lao Jing's arm and shook it vigorously, which almost didn't break up Lao Jing.

"Huh...... , light, light, light......"

Jing Jun suddenly broke out in a cold sweat, this little girl was too violent.

Feng Chime's little face flushed, realizing that he was a little carried away, his little hand immediately became weak and boneless, gently kneading Lao Jing's arm, and at the same time full of apologies, blowing like an orchid, and couldn't help but apologize.

Jing Jun changed from the initial pain to enjoyment, and slowly closed his eyes to accept the girl's massage.

When the wind chime saw Lao Jing close his eyes, he almost groaned and hummed, his little face tensed, and he pinched Lao Jing's arm a little harder, and said angrily: "It's very enjoyable, right, what about now?"

Lao Jing Meng opened his eyes and said with a smile: "Hehe, it's okay, it's okay, let's continue to discuss......"

"Gatling's wheel principle should be a more reliable choice to prevent the barrel from heating up too quickly, but this power is estimated to have to return to the most primitive hand-cranked method. ”

The wind chimes also stopped frolicking, pouted slightly, and said helplessly: "Then what's the way, you can generate electricity every day, but I haven't seen how you can make the motor spin?"

Jing Jun was angry, who said that the lightning mage is used to generate electricity to provide electricity, but how could this be argued with the beautiful girl in front of him.

He suddenly raised his eyelids a little tiredly and looked at the wind chimes that were covering his mouth and stealing fun, and said, "Okay, don't talk about those useless ones, then let's start with the six-pipe Gatling, but don't force yourself too much, take your time." ”

The wind chime put away the meaning of teasing, nodded his head, and savored the faint concern in Jing Jun's words.

Next, the two threw themselves into the intense development of a machine gun.

Today, the Gatling rapid-fire machine gun in the Jing Army's ammunition depot is driven by an electric motor with a minimum rate of fire of 6,000 rounds per minute, which is a life harvester when used in war.

Unfortunately, this murderous weapon is now just an ornament that can provide memories of the earth, and it cannot show its terrifying power at all.

Jing Jun dismantled the motor and explained in detail to the wind chime the precautions for turning into a hand-cranked drive, and the latter was also writing and drawing with an extremely serious attitude, and after more than an hour, she actually drew the drive system in the absence of physical reference.

Jing Jun held the woolen paper in his hand, and couldn't help but be amazed, at least now he couldn't see anything wrong with the drawings.

As for the rest of the wheel design, it is not difficult, the caliber of the gun has not changed, even so, the gun should be undiminished after it is completed.

Two days have passed in the blink of an eye, and the dog has recovered without illness, and his external injuries are not very serious.

The snake female assassin and the birdman that Jing Jun had been worried about surprisingly did not reappear, and it is unknown whether they retreated in the face of the difficulty or gathered strength.

The Sea Clan still didn't make any moves, as if this time the momentum came to the mainland just to practice routinely, of course, the word "training" is also understood.

The Gatling drawings of the wind chimes have been drawn, and the Minotaur craftsmen have already begun to build the parts, and with the experience of building firearms for more than a month before, they are no strangers to the drawings brought by Jing Jun, the leader of Donghai Town, although they can all see that the parts this time seem to be quite demanding.

There is another thing that Lao Jing has long forgotten, the leatherman of Donghai Town actually sewed a set of soft armor for him and the wind chime cat Yanran and others.

The dog took the thing to him with a smile on his face, he didn't figure out what was going on, if you want to talk about defense, the body armor on his body is better than the fine iron armor of the Minotaur warrior, and the main thing is that compared to the iron armor, the body armor is many times lighter.

So what's the deal with the gray-black dress in the hands of the military advisor?

As soon as the dog explained without illness, he suddenly realized that these gray-black clothes were actually sewn from crocodile skin under the hard armor of the crocodile people.

As mentioned earlier, the defense power of the crocodile clan's thick armor is second only to the dragon scales, and the dragon scales are just legends, and who dares to provoke the mysterious guardian god of the continent without opening their eyes.

Therefore, the thick armor of the crocodile clan has become the top-level defensive equipment that all cultivators on the mainland are trying to obtain, but they also know that the crocodile clan is the third of the top ten strong armies in the mainland, and they are basically active in the treacherous mountains and rivers of southern Xinjiang, and no one dares to go to southern Xinjiang to provoke the murderous crocodile warriors just to get a piece of armor.

However, it is inevitable that the crocodile clan will send people out of southern Xinjiang because of a certain task, and at this time, there will be two situations.

First, the crocodile warrior mission was completed and returned triumphantly.

The second is that the mission fails, they are captured or killed, of course, those who are basically captured will eventually be killed, and then they will begin to peel off their skin and make armor, and the end will be miserable.

Now the top-level protective armor circulating on the mainland is basically obtained in this way.

Lao Jing had heard a little about top-grade crocodile armor later, and now he remembered that after killing more than a dozen warriors chased by the crocodile clan in southern Xinjiang, Niu Qing had received eight corpses in the ring.

At that time, he said that when he returned to Donghai Town, he would eat delicious crocodile meat and pick crocodile skin to make armor, but he didn't expect that it would take almost two months to sew this kind of top-level armor after returning from southern Xinjiang.

The mood is a little excited to take the armor, the feel is slightly cool, but the texture is extremely soft, at a glance it is difficult to think of a big crocodile that walks upright, they do not have a restrained appearance when they say that behind the back, even the face is full of cracked carapace, like the dry skin of a century-old tree, there is no beauty at all.

But now the soft armor has removed the outermost layer of ugly surface armor, and the rest is that the inner toughness and protection are not weaker than the surface armor, just look at it to know that there will never be any discomfort on the body.

The crocodile people are tall, and it stands to reason that there should be a lot of skin peeled off, but it is not very rich to get the soft armor inside and sew it into the next set of armor, but if you want to follow the old Jing Wind Chimes of their size, the material is more than enough.

The Minotaur has no selfish intentions, a total of eight wicked corpses, Niu Qing originally explained clearly, Jing Jun, Feng Chime, Mao Yanran, and Hate Tian must each have one set, and the rest are considering other people, and Niu Ben has no opinion.

In fact, this is also their bull-headed people's show of favor in order to completely leave Jing Jun and the others, of course Lao Jing can feel it, although his current attitude feels that these people are doing this a bit too much, but the things are really good, and it is extremely necessary to wear them on their bodies.

As for the wind chimes, they are already invulnerable, and it stands to reason that they don't need to wear any protective equipment, but she was cut to pieces by a group of giant python warriors in southern Xinjiang, and her body was almost half naked.

So, she has to wear one!
