At night, there was silence all around, only Chen Xin and his party were marching in a hurry, and during the day there was a bit of a big movement in the military fort, and it was a fire gun and a large grenade, Chen Xin was afraid that someone around him would hear the sound and go to check, so he decided to march quickly overnight, and went to a Jurchen nobleman's Tokso, which had only 8 households 50 miles away, to repair. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Chen Xin walked in the front, with a pet bag hanging from his waist, and inside was a biochemical creature that looked like a small milk dog, only to see the long stupid puppy constantly sniffing his nose, trying to distinguish whether there were people in the surrounding forests and fields.

This is Chen Xin inspired by the Great War during the day, a vigilance for a biochemical dog, in order to facilitate carrying, temporarily adopted the size of a small milk dog, but its vigilance system is extremely developed, in the sky eagle falcon can not see the shelter, the biochemical dog has a great use. If it had been in the previous war, it wouldn't have been attacked.

Arriving at the previously selected Tokso, at the usual military meeting, Chen Xin not only drew the map detected by Eagle Falcon No. 1, No. 6, and No. 7, but also marked on the map the general location and number of people in the Zhuangzi that Dog 1 smelled.

Facts show that as long as the preparation is sufficient, and the strength crushes the opponent, there will indeed not be too many accidents, with everyone's military quality and ability, they quietly took down this Zhuangzi, and after cleaning up the Jurchen officials and family members inside, everyone began to take turns to stand guard and rest.

Everyone in the resting room was a little sleepless, and they opened the conversation box to chat, but the most of them focused on the power of the firecracker, although the firecracker is not easy to hit accurately, but the armor-piercing ability within a certain distance is deeply imprinted in everyone's minds.

Yesterday three brothers were hit by firearms, the first time a little long, the slipper's double armor did not block, and later when the charge everyone added a piece of armor against the shield, at close range there were still two wounded.

CHEN XIN LISTENED TO THE CHATTING IN THE ROOMS ON BOTH SIDES, FIDDLING WITH A CAPTURED ARQUEBUS IN HIS HAND, THE SMALL MUZZLE, ROUGH WORKMANSHIP AND PRIMITIVE FIRING MECHANISM ALL SHOWED THAT THIS WAS A PRIMITIVE BIRD GUN, ONLY 10MM CALIBER BIRD GUN ACTUALLY PENETRATED THE SHIELD AND INJURED THE SOLDIER WEARING THREE LAYERS OF ARMOR BEHIND HIM WITHIN 15 STEPS, NO WONDER THE GUN WILL REPLACE THE COLD WEAPON, AND ANYONE WHO HAS TRAINED FOR A FEW DAYS CAN USE THE BIRD GUN TO FIGHT, AND THE DAMAGE CAUSED BY THE STRONG ARCHER WHO HAS BEEN TRAINED FOR MORE THAN 3 YEARS MUST BE MOVED.

With Lao Bai here, Chen Xin is sure that he can explore through experiments and transform a batch of Minne guns with a unified caliber and rifling, even if it is fired by the arquebus, it will not affect the accuracy, but Chen Xin is a little hesitant, the musket can only play the maximum role if it is equipped with a certain scale, and it is now inside the Houjin, if the Houjin gets this kind of Minne bullet, although the agricultural society cannot make ammunition that meets the requirements, there will be problems that cannot be solved at this time, such as hanging lead, but it will also enhance the enemy's strength to a certain extent.

What to do? Looking around, when he saw that the slip and the other two brothers who had been seriously injured and had been treated were lying on the bed, and there were still some pale faces, Chen Xin's hesitation was left behind, in order for the brothers to not use their lives to attack the enemy's firearms troops, we must make the Migne gun as soon as possible.

I, a person from the world of later generations, how can I be afraid of the spread of technology, with my hundreds of years of historical experience, I can't guarantee that I will surpass these natives in technology research and development, so I don't have to think about overthrowing Houjin, just wash and sleep obediently.

Thinking of this, Chen Xin gave Lao Bai a task to start research and development to improve the quality of arquebuses, rifling, Miner's bullets and other projects.

Chen Xin had already gotten a small steel knife before, allowing Lao Bai to scan the atomic structure, and now Lao Bai directly made an all-steel seamless steel tube as the barrel, so that not only is the barrel extremely smooth, but the ammunition made by Lao Bai also fits the barrel.

Chen Xin asked Lao Bai to imitate other parts, and improved the butt to make it more close, and a beautiful arquebus appeared in Chen Xin's hand, although he had not yet carved rifling and made Minne bullets, but Chen Xin was suddenly moved in his heart.

Chen Xin later saw the accuracy test of the military shotgun firing a single-headed bullet on the Internet, and remembered that the tester used the M870 long-barreled shotgun to fire a single-headed bullet, and hit the head of the humanoid target at 200 meters.

So, now I have Lao Bai, the processing accuracy of firearms far exceeds that of later generations, can I make a smoothbore gun that can hit a target of 200 meters in small batches?

If it can be done, then not only will it avoid the leakage of rifling and Miner's ammunition, but it will also have a precision smoothbore gun that has not been imitated for hundreds of years in this era.

Thinking of this, Chen Xin immediately became excited, and began to sketch the smoothbore gun he wanted to build in his mind.

First of all, the caliber should be expanded, otherwise there is no power if it shoots far, and the 12-gauge caliber used by the shotgun in later generations is very good, and the projectile fired under the caliber of 18.5mm can retain as much kinetic energy as possible in the effective range.

Secondly, in order to prevent the reduction of the firing range caused by air leakage from the front, the projectile should be changed from a circle to a semicircle with a profile, and this also increases the difficulty of imitation by others.

Finally, there is the problem of propellant, the propellant of later generations has been studied and improved for a long time, and it can be used to emit as much kinetic energy as possible with as little propellant as possible, and it is not capable of creating a future propellant, so Lao Bai is required to purify the gunpowder to the greatest extent and can also achieve good results.

The last is to calculate the strength of his brothers, according to their physical capacity, calculate the maximum amount of gunpowder that can be used for each round of ammunition, and then calculate how thick the barrel should be according to the amount of gunpowder fired.

In the end, Chen Xin took the first gun he "designed" and looked around excitedly.

Chen Xin named the gun "Type 1 rifle".

This gun has a caliber of 18.5mm, a total length of 1500mm, and a weight of 7.5 kg, with a strap on the body, a through strip under the barrel, a crosshair at the front end of the barrel, and a ruler in front of the arquebus faucet, and there are no scales and holes on the scale for the time being, which can only be determined after a large number of test firing.

Chen Xin took the ammunition made by Lao Bai and tried to reload it a few times, it was very smooth at the same time, Chen Xin nodded with satisfaction, the barrel is thick and strong enough, to ensure the amount of charge, and the weight of the whole gun ensures that ordinary soldiers can't raise it to aim after getting it, except for the slow reloading speed of the front gun and the ignition method of the arquebus, everything is perfect, just in line with the use of himself and his brothers at this time.

Chen Xin believed that its accuracy could sweep all the firearms of this era, looking at the deep night, Chen Xin forcibly suppressed the urge to test the gun, and continued to make 19 guns with the seized raw materials, making up enough equipment for 20 people, thinking of the number 19, Chen Xin thought of Wang Changfu who was executed by himself, sighed deeply, and lost the interest just now, turned around and picked up the armor and weapons damaged today, and began to command Lao Bai to repair them.
