After inspecting the production of auxiliary weapons such as bayonets and long-handled axes, Chen Shuren also walked around other workshops in the Bingzhang Workshop.

It was found that after several months of preparation and running-in, the musket production work in Bingchaofang in Huangzhou began to find a way out. Compared with the pipe rolling and boring technology at the end of last year, it has been greatly improved.

The craftsmen made two arrangements according to Chen Shuren's instructions.

On the one hand, we developed a foot-type boring machine according to the idea of ​​a pedal lathe and a foot-leg grinder.

On the other hand, we simultaneously tinker with the technique of "hot forging the rolling tube with iron plates, then forging and welding, and finally outsourcing the red hot iron hoop, tightening the hoop when cold", trying to use musket technology without boring.

After testing, the process of the musket made by the boring method is similar to the original one, but it further improves the boring efficiency. Originally, a barrel was drilled slowly for more than a month and was easily eccentric; now it can be shortened to about twenty days to drill the hole, and the quality has been improved.

The newly tested tube rolling method is definitely a little worse in quality than the boring method - this is easy to understand. One is "seamless steel pipe" and the other is "seamed steel pipe". The strength of the joints is definitely worse.

Craftsmen can only be taller among short men. Even if the quality is poor, they must pick out the relatively best among the poor.

When Chen Shuren left, they didn't teach them how to weld the rolled pipes. The main reason was that Chen Shuren himself could not know too comprehensively. He didn't know how many types of welding metal techniques were used in the Ming Dynasty.

So Zhou Tiedan took two months to try it out.

First, we tried the casting welding method of melting tin lead and melting bronze. We wanted to use bronze that is easy to burn into liquid to cast the joints of the iron pipes together. But in the end, we found that the place where the copper and iron bonds were too unstable and could not withstand high pressure, so we had to give up.

Fortunately, no one was killed during the experiment. Everyone carefully placed the experimental musket in an iron barrel and fired it. The explosion could not hurt people. Most of the splashed debris and gunpowder gas were absorbed by the iron barrel.

After the casting and casting and welding method fails, we have to use the most difficult and relatively expensive forging and welding method. That is, when making the pipe roll, make the two ends of the iron plate slightly thinner, and then try to heat and press the two ends together, and repeatedly beat and fuse them with great force.

The materials used in the forging and welding method are uniform, so there is no problem of "insufficient joint strength between different metals".

However, the deformation degree of the iron pipe rolled out by the forging and welding method will be more serious than that of the boring method and casting and welding method. After the fabrication, it is necessary to add a process to repair the inner wall with an inner turning tool.

Fortunately, Zhou Tiedan and others have already promoted it according to "The Book of Heavenly Works" and have created all the foot-type boring machines and grinding wheels, and the boring machines to the lathes, that is, the cutting heads have slightly changed. Craftsmen who have been widely inspired can easily learn from each other.

The final barrel cost can also reduce the labor cost by more than half compared to the boring method. If the slight deformation of the inner wall of the barrel is not modified, it will probably be cut by half and directly to the knee price. Unfortunately, the garbage that is too poor and easy to explode is definitely not used by Chen Futai.

These technologies have been repeatedly developed in the past two months. Unfortunately, the R&D cycle is too long, so only a few samples were made, and a musket has not been mass-produced yet.

Chen Shuren asked Zhang Huangyan to check the production plan and capacity of Bingzhafang, and learned that "if you want to ensure that 1,200 bayonets and long-handled axes are produced first, then start producing muskets."

Then the production task of cold weapons can be scheduled until early April, and the production of muskets will begin in April, which will approximately enable each blacksmith to produce one semi-new boring musket or three to four reel muskets per month.

There are now 80 experienced military blacksmiths in Bingzhaofang in Huangzhou, and the production capacity of 120 bored muskets or 300 reel muskets per month.

If you want to accelerate, you have to find ways to add machinery and equipment, recruit more skilled military blacksmiths, and spend more money to solve the source of iron ore...

It is not that easy to expand the supply chain quickly, and many links will be choked.

The blacksmiths who know how to make military equipment only have that little people in each mansion, and are strictly controlled by the imperial court. Shenshu people cannot dig out ready-made products directly. To transfer from ordinary blacksmiths who make iron and agricultural tools, or to bring apprentices, they also need time to train them.

The procurement of steel raw materials cannot be expanded casually. Now he still needs goods to buy from Huangshi Tieshan (Daye Iron Mine) in the other side of Zuo Liangyu.

None of these can increase production capacity within a few months. It is better to expect rapid promotion and expand the territory to occupy more resources.

Therefore, within eight months after April this year, Shen Shuren estimated that his military production capacity could only produce about 1,000 bored muskets or 2,500 reel muskets in total. If it is also equipped with melee cold weapons, the production capacity could be reduced by one quarter.

I can only rely on these weapons to win a battle first, then occupy more territory and resources, and slowly snowball.

...

The military inspection lasted until noon. After lunch, Shen Shuren watched the soldiers practice again.

With seven or eight hundred bayonets and long-handled battle axes officially installed in the musket force, the 1,000 bird gunners/Lumi gunners of the Shen family army have been practicing assassination and fucking for more than a month.

The turtledove gunman, of course, practices the long-handled battle axe tactics in corresponding ways.

After the Lantern Festival of the first lunar month, Zuo Zixiong and Pizarro practiced their lives.

At the beginning, there were not enough bayonets, so they were trained in three batches. Some people were sleeping and resting, and others were trained with bayonets. Later, the number of weapons increased, and they were fully qualified to take turns to two batches of training.

Zuo Zixiong didn't know much about bayonet tactics. In the first half of the month, he could only watch it, and saw that the Spanish instructor with high salaries led it.

Fortunately, Zuo Zixiong is talented and has excellent martial arts skills. After watching this for more than ten days, he roughly understood the difference between the bayonet and the spear. Then he joined in and personally brought a group of soldiers to practice, so as to stagger the time with Pizarro.

Now it has been more than 20 days since Zuo Zixiong personally practiced assassination, and the spirit of the troops is different.

In order to appear closer to the soldiers, Chen Shuren did not bring a folding fan, but instead replaced it with a square round fan with iron-faced bones to block the sunlight in front of his eyebrows and carefully examined the soldiers' assassination.

The sun was quite strong that day, and the soldiers stabbed at the tightly tight scarecrows under the scorching sun.

A few dots were dyed with vermilion on the scarecrow, at the crossing position between the left and right arms of the scarecrow and the top and the middle as the target.

Before each stab, there were officers calling orders, which were nothing more than "left, left and right". Wherever the command required, you had to poke the corresponding red dot on the scarecrow quickly and accurately.

In actual combat, of course, it is impossible to have such commands, but everyone adapts to the situation and counters according to the enemy's moves. However, during training, such strict requirements are also to ensure that the soldiers use their swords quickly, accurately and ruthlessly, and hit wherever they point.

"Six rows and eight columns, no difference between left and right! Write down the mistakes once, stay and practice twenty more times later!"

"Nine rows and three rows, the knife is unstable and it is not stabbed! Practice ten more times!"

Several soldiers were always in the queue, carefully checked, and recorded the soldiers who had insufficient accuracy and response.

According to Zuo Zixiong's arrangement, these musketeers are now trained in batches according to odd and even numbers. The number of bayonets in the army has reached two-thirds of the total number of troops, so every time they rotate, about one-sixth of bayonets will be added.

This part can be used to specifically serve soldiers who perform poorly and have distorted movements. They can go back to rest on their own mark and practice with the people who have changed into it.

After watching for a while, Chen Shuren had the illusion of visiting military training and assassination exercises in later generations. Although the tricks were different, the assassination movements may not be refined and simplified to be efficient enough, but the soldiers' discipline and orders were definitely not comparable to ordinary Ming soldiers. The entire military formation had already permeated a murderous aura.

The newly transferred military officers with Chen Shuren were even more surprised. After all, the discipline of the Ming Dynasty garrison troops they had seen before was really much worse.

Yan Yingyuan and Zhang Mingzhen were both convinced: "Although the moves may not be exquisite, the momentum is uniform. When encountering a thief, you will definitely be able to tell at a glance that this is an elite army."

Only Zheng Chenggong didn't think these exercises were amazing. This was also related to his "experienced" and deep understanding of the weapons of the Red Barbarians.

In the West, between the 1630s and 1640s, early bayonets also appeared, which was the product of the French during the 30-year religious war in Europe (1618-1648).

It’s just that the Western bayonet is in a dagger shape, and it is directly inserted into the barrel. The Shenshu Ren is a hoop-shaped one, which does not affect the robbery, and the assassination effect is more professional.

Zheng Chenggong had seen French bayonets from the Spanish. At this moment, he saw Brother Chen using it on a large scale for musketeers, and he was also eager to try: "Brother Chen, I will do this method of guns and swords, so may I let me try it?"

Zuo Zixiong, who was beside him, immediately looked at Chen Shuren, as if he was asking for instructions with his eyes. Chen Shuren nodded, and then Zuo Zixiong handed over a Lumi gun with a bayonet.

Zheng Chenggong came to a cross-shaped scarecrow. He listened to the command and went up and down, left and right, and was quite accurate. He stabbed quickly the first time he started.

After stabbing, he also summarized with a little reminiscence: "The use of this gun sword is similar to that of a long spear, but it is just a little shorter, but the advantage is that it can make the firearm soldiers far away from now on, and they can also have the power to fight when encountering cavalry. Zuo Dusi, how is my sword technique?"

Zuo Zixiong looked embarrassed and asked Chen Shuren with his eyes. Chen Shuren knew that he must have looked down on Zheng Chenggong's bayonet technique and said with a smile: "It's okay, just say it, Brother Zheng and I have a frank relationship with each other, without using any politeness to pretend."

Zuo Zixiong then said bluntly: "Young Master Zheng's sword technique is really not a good match. It only takes advantage of these two advantages of accurate stabbing and quick reaction. However, the technique of using force, whether the lower plate is stable and whether the waist and horse are combined together is just a fancy way.

When the enemy is strong and powerful, or the cavalry charges, your musket will fall off as soon as you touch it. The musket and the gun sword are only seven feet long after all, which is still shorter than the spear.

The spear should be at least eight feet long, and there are more than one meter, so the tail can be used to support the ground. The use of a musket and a gun sword is never possible to rely on the ground.

So you have to learn the big gun technique that holds the gun's tail and prystal force. The strong right hand is behind, the left hand is in front, and the right hand is pressed down while poking forward, lifting the sword head, and having to hold it at any time on the gun support.

The ordinary formation and gun technique that can be used to rely on the ground is to use the strong hand in front and the weak hand in the back. When stabbing, it seems that the force is stronger, but the center of gravity is unstable, so it is not easy to use the force."

Zuo Zixiong was also very dedicated to his superiors' friends. He kept talking about him and learned from his Spanish colleagues for a month and a half, and then combined his martial arts skills to summarize his bayonet skills, and told Zheng Chenggong without reservation.

Zheng Chenggong had a good understanding and soon understood the essence of the bayonet technique: the key is to use a lever hand, the left hand only holds the musket from the middle fulcrum, and the right hand behind holds the butt stock while pressing down and prying the tip of the gun up.

He pondered for a while, stabbed a few more shots, and soon felt that the calmness of the assassination force was completely different, and it was not easy to be blocked and pulled and staggered, causing the empty door to open.

"Zuo Dusi is really a martial arts master. He mastered these Qimen weapons that he had never seen before so quickly. He could still get the essence. If you have the chance in the future, you should ask more questions!" Zheng Chenggong was also very sincere and bowed directly to Zuo Zixiong.
