Since the Qing army entered the customs from Dushikou in Xuanfu Town in early July, it has broken through nearly 50 cities in a row, killed countless Ming people, and looted countless property.

Zhu Cihong felt that the situation was becoming more and more severe, first inspected the Yongwei Battalion, and now the Yongwei Battalion is in excellent condition, especially after the reward, the soldiers are full of enthusiasm and eager to go out again.

The Brave Guard Battalion has been replenished and expanded to 6,000 men, and the more than 2,000 people who joined later are all excellent soldiers selected from the new battalion, who are all outstanding in ordinary training and only need to go through a baptism of actual combat.

Zhu Cihong was very satisfied with the situation of the Yongwei Battalion, and then he went to the Military Bureau and the Anmin Factory to inspect the research and production of firearms.

Today's military warfare bureau has grown from more than 200 to 1,200 by vigorously recruiting craftsmen with high salaries.

Zhu Cihong implemented a system of bringing new craftsmen to these craftsmen, and each old craftsman brought several new craftsmen to teach their skills, and the qualified firearms made by the new craftsmen were rewarded, and the old craftsmen also received a commission.

Similarly, if the new craftsman fails to produce a firearm, the old craftsman will also be punished, and in this system, the old craftsman can only teach the new craftsman hard to work hard, and get more for his work.

Due to the very generous R&D rewards of the War Bureau, there are more and more research groups spontaneously formed by craftsmen, and the enthusiasm and atmosphere of R&D are quite good.

Just recently, according to Zhu Cihong's idea, an old craftsman has studied the imitation rotary rifle many times, and finally improved, greatly reducing the weight and size of the original bulky rotary rifle, which is quite the prototype of the revolver in later generations.

However, it is only a reduction in size and weight, and there is not much breakthrough in performance, the biggest improvement is that the original four rounds of ammunition have been increased to six, and there is still not much improvement in reloading, which is still so laborious and time-consuming.

Zhu Cihong knew that if he wanted to imitate the revolver of later generations, he had to develop a primer and a bullet for later generations, the bullet was the main body, and the gun was only the carrier.

For example, rifled guns, which are more advanced than flintlock guns, that is, rifled guns, have a spiral rifling that allows the projectile to rotate and fly stably in the air, improving shooting accuracy and range, and the firing range can reach more than 900 meters.

Although the manufacture of rifled guns is a bit troublesome, with Zhu Cihong's cognition and the manufacturing ability of the War Bureau, it can be manufactured, but it is almost useless to manufacture guns alone, and the core and most troublesome thing is bullets.

In terms of the relationship between bullets and firearms, bullets determine guns, and there will be guns when bullets are there, and only when bullets make fundamental breakthroughs in new principles, new structures, new materials, and new technologies can guns make a qualitative leap forward.

The current smoothbore gun bullets based on steel balls and lead balls are not suitable for rifled guns at all, and they are not as good as self-generated Lumi guns.

In 1476, there were spiral rifled guns in Italy, and at the beginning of the 17th century, the Danish army was the first to use rifles, but it was not until the second half of the 19th century that rifled guns became the mainstream, because the problem of loading and bullets was never solved.

Because rifled guns of this era, when loading bullets (wrapped in lubricated cloth), had to be hammered into the barrel with a mallet, which was very time-consuming to reload, and far less fast than the self-generated Lumi guns of the Yongwei Battalion.

If you want to use the advanced rifles of the later generations, you must solve the problems of breech loading and primer bullets, and these problems are not complicated, Zhu Cihong also talked to Sun Heding in detail, but the development and manufacture of bullets are quite difficult, and they cannot be made casually.

According to the general understanding of later generations, Zhu Cihong said that the caliber error between the bullet and the chamber of the gun should be within one millimeter, and he didn't know exactly what it was, after all, he was not omnipotent, and he knew everything.

With the ideas provided by Zhu Cihong, if the War Bureau continues to develop and succeed in the development of rear-loading guns, spiral rifling and bullets, it will be a matter of time.

Zhu Cihong is not in a hurry, because it is useless to be in a hurry, the bullet can be said to be a product of civilization that integrates physics, chemistry, materials science, aerodynamics and technology, and everything needs time to solve.

Science and technology and civilization do not come out of nowhere, Zhu Cihong's advanced ideas can only be produced in advance, avoiding fewer detours, and cannot be achieved overnight.

If everything is made very easy because of the traverser, it will not take a few years for Daming's spacecraft to land on the moon.......

After inspecting the War Bureau, Zhu Cihong went to the armor factory located in the southeast of the Dongcheng District of Jingshi, which is a place to make armor, guns, bows, arrows, and gunpowder.

In the 33rd year of Wanli, the officers and soldiers of the three major battalions of the capital went to the armor factory to receive gunpowder, and the dead eunuch who supervised the gunpowder ordered the craftsman to split it with an iron axe because of the old gunpowder lumps.

Needless to say, nearly 100 officers and soldiers waiting to receive the gunpowder were burned to death on the spot, and countless craftsmen and nearby residents in the factory were killed and injured.

A few years ago, the same place was bombed again, destroying many houses, and even the large stone mill that made gunpowder was blown under the wall of the Paozi River.

After Zhu Cihong asked Wu Zhong to take over the War Bureau and the Anmin Factory, he cleaned up the armor factory by the way, and also organized a set of safety measures in accordance with the Anmin Factory.

At the test site of the armor factory, the ambassador of the armor factory was holding a flintlock pistol with a bayonet in his hand, and he said with a smile on his face: "Your Highness, this is a bayonet made according to your requirements. ”

Zhu Cihong circled around the musket with a bayonet mounted on it, and was quite satisfied with the appearance, and then ordered someone to test the penetration of the bayonet on a dummy with different armor thicknesses.

According to the records of the "Ming Huidian", in the second year of Jingtai (1451), the Ming Dynasty appeared for the first time to install a spearhead on an iron gun for assassination, integrating the performance of muskets and spears.

It was not until more than a hundred years later, in the mid-16th century, that the invention of installing spearheads on shotguns for assassinating prey appeared in Europe.

In later history, the bayonet was created in the French army in 1647, when a French musketeer thought it was troublesome to fight in close combat with a musket in one hand and a short sword in the other, so he stuck his short sword in the muzzle.

It was such a whim invention that changed the pattern of warfare in later generations, and all pikemen gradually lost their jobs and withdrew from the stage of history.

Since the bloody battle in Liangxiang, as soon as Zhu Cihong returned to Beijing, he immediately notified the armor factory to produce bayonets, but this kind of bayonet was not a flat-headed bayonet during the Anti-Japanese War in later generations, but a three-edged military stab.

Zhu Cihong considered that the flat-headed bayonet had relatively high requirements for steel, and it was very difficult to use the current productivity of the Ming Dynasty, and most of the Qing troops wore two or three layers of heavy armor.

Zhu Cihong also considered the spearhead in the early Ming Dynasty, but considering that it was too bulky and was eliminated by history, Zhu Cihong could only give up, and finally he thought of the three-edged military thorn when he was in the army in the later generations.

The three-edged army bayonet body is prismatic, and the material requirements are lower than those of the flat-headed bayonet, and the structure is also stronger.

The main thing is that the Mitsubishi Army's assassination is very high, it has a prismatic appearance, cold color, and its lethality rate is very high.

The wound pierced by the three-edged spear is generally a square hole, and the blood not only flows out along the groove on the spot, but this wound cannot be bandaged and stopped, especially on the battlefield, there is no chance to call an ambulance or anything, just wait for death!

The shortcomings of the three-edged bayonet are also obvious, the function is relatively simple, and it lacks the functions of cutting and cutting that the flat bayonet has, so it can only be used as a spear.

Due to the short period of time, the armor factory has only produced 500 three-edged bayonets overtime, all of which are made by the specifications of the guns of the Yongwei Battalion muskets.

Theoretically, the installation of the bayonet did not affect the firing of the musket, but the current flintlock reloading mode is all front-loaded, and the installation of a three-edged bayonet in front of the musket definitely affects the reloading speed.

In order to avoid this trouble, Zhu Cihong used the earliest split-type installation method, using a casing bayonet to install a three-edged bayonet, and in peacetime battles, the three-edged bayonet was mounted in the sword holster and attached to the waist, and then installed in close combat.

In view of the fact that the triangular military thorn is too domineering, in order to avoid accidental injury during training, the training of the Yongwei Battalion on weekdays does not open the blade, and the blade (knife tip) is only opened when it goes out, and it comes with a small grinding stone, and the time it takes to open the blade is about five minutes.
