Resetting the winding distance of the rifling is not difficult for Daming, who already has the processing technology. It is nothing more than adjusting the progressive speed of the barrel to obtain rifling with different winding lengths.

That night, the craftsmen had already re-turned a few barrels and quenched them overnight.

In the afternoon of the next day, Zhu Zhanji went to the shooting range of Yulin Weixue again, tried several barrels with different winding lengths in turn, and determined the most suitable one.

The length of the pistol is much more important than that of a pistol, the range of the pistol is limited, and the key is muzzle velocity and kinetic energy.

However, in addition to muzzle velocity, the spear also has the most critical range and the degree of rotation of the bullet, and the degree of rotation also determines the accuracy of the bullet.

The best rifling design was experimented with, and the spear was completely finalized.

Next, it is necessary to determine the crosshair of the gun according to the arc of the ballistic.

With any firearm, the trajectory of the bullet is also with a curvature. The reticle of the barrel muzzle is calculated according to the arc of the trajectory before it is finalized.

For a layman, it only takes three points and a line to accurately shoot a bullet at the target, but for a gun designer, the adjustment of the front sight is actually a very complex calculation process.

At this time, the nobles and generals of the whole capital also got the news, and His Royal Highness developed a newer weapon.

For someone who doesn't know about firearms, the gun is already the most powerful weapon they can think of.

Any trained recruit, after a maximum of three months of training, can become a qualified musketeer.

Although the power of the musket is slightly lacking, and the range is about the same as that of a longbow, it is far easier to pose a threat than a good archer because of its large coverage and ease of use.

A powerful bow and arrow takes three years to make, and a good archer requires years of training.

The appearance of muskets has made the gap between the physical fitness of the Ming soldiers and those grassland peoples disappear.

With only a simple training, a weak Ming soldier can kill several times his own cavalry, a strong man.

In the past few years, the reason why Daming has been able to firmly hold Beiming Mountain, so that the grassland tribes dare not rebel repeatedly, is because of the irresistible power of the musket.

No matter how powerful the rider is, no matter how powerful the shooter is, in the face of the musket of the Ming Dynasty, he has lost his threat.

Especially after the invention of barbed wire in the Ming Dynasty, this kind of barbed wire that can be transported and arranged at will has lost the ability to maneuver that the grassland people are proud of.

The once steppe wolf can only be like a docile sheep.

After hearing that Zhu Zhanji had come up with a new weapon, the power was far greater than that of the previous firecracker, and everyone's curiosity was aroused.

But when Jin Kuo saw the power of this gun with his own eyes, he knelt down and asked Zhu Zhanji to seal the gun and block the technology.

In terms of fame, Jin Kuo is far inferior to Wang Yan, Zheng and them, the seven eunuchs who have been well-known at home and abroad since the early days of the Yongle Dynasty.

However, he is the most trustworthy eunuch in Zhu Zhanji's hands.

From taking care of Zhu Zhanji when he was a child, to going to Ningbo to help Zhu Zhanji preside over trade, and now helping Zhu Zhanji as a big housekeeper, Jin Kuo has been doing very well.

His fate is closely tied to Zhu Zhanji, and there will never be two hearts.

Now, Zhu Zhanji's side, except for Li Liang, who is not Jin Kuo's person, Sun Lin and Liu Wan of the Counseling Department, they are all Jin Kuo's apprentices.

This kind of intimate relationship makes Jin Kuo always think about Zhu Zhanji wholeheartedly.

His reason is that the power of this gun far exceeds today's security capabilities, which will greatly threaten Zhu Zhanji's safety in public in the future.

Zhu Zhanji's purpose in making the musket was to make the Ming Dynasty's force stronger. But now, the popularity of this musket will not be of much help to the Ming Dynasty, but will pose a threat.

In the case of ordinary firearms, because five or six lead bullets are fired with gunpowder. This kind of gunpowder is not powerful enough, and the sealing is not good enough, the range is only 200 meters at most, and after 100 meters, it almost loses its lethality.

Therefore, Zhu Zhanji will not be afraid of assassination, with his ability, an assassination from a distance of 100 meters can hardly hurt him, and with this kind of long fire, it is almost impossible to get close to him within 100 meters.

However, this new type of musket uses an eight-millimeter bullet with a range of 800 meters, and it has lethal damage within 400 meters. This also means that if someone tries to assassinate him, it will be difficult to prevent it.

Jin Kuo believes that Daming firearms are invincible in the world, and this kind of musket that exceeds the ability to defend should not appear.

Since an ordinary musket is already irresistible to other countries, and is already standing on top of all weapons, why would he come up with such a weapon that threatens him?

Although he has always struggled for the great goal of Chinese rejuvenation, in his heart, he has always been an extreme egoist.

He also never put the interests of others above his own noble spirit, so the idea of promoting this musket became hesitant.

That night, Zhu Zhanji spent an hour alone in his study. In the end, it was decided that the new gun would be displayed as usual, but it would be popularized, and it would be postponed for a while, at least when Zhu Di came back to see what he thought of this new weapon.

Although Zhu Di is the biggest warmonger, he is still quite skillful in grasping the balance between politics and military.

In his original history, he attached great importance to the development of new weapons, artillery, muskets, and carried forward in his hands.

However, after Zhu Gaochi and Zhu Zhanji came to power, the research and development of firearms was not taken seriously, and the manufacture of muskets became worse and worse.

How to strike a balance between the contradiction of consolidating his rule and increasing his firepower, Zhu Zhanji could not seek advice from others, but could only seek advice from him.

With such an idea, Zhu Zhanji directly issued an order to confine down all the craftsmen involved in the manufacture of new guns, especially bullets.

Before Zhu Di returns, they will temporarily lose their freedom and cannot leave the Xiamaqiao Farm.

Although there was no new gunpowder, no primer, they could not make powerful new guns. But this processing technology itself is the biggest secret.

With such an idea, the remaining little mercury thunderate was arranged by Zhu Zhanji to produce round-tipped pistol cartridges, and this fifteenth-century Boleta pistol was his sharpest weapon in this world without threat.

And the ballistics and accuracy of this gun still need to be adjusted, and a lot of bullets are needed to practice.

Dismount Bridge, Yulin Weixue.

"Li Zifeng, you are well-informed, the day before yesterday, His Highness said that everyone should observe the new weapon, why did you block the shooting range today?"

"I don't know about this...... fifteen-year-old Li Zifeng still has the flamboyance of a young man, and he couldn't help but whisper again: "Since His Royal Highness wants to keep it secret, there must be a reason to keep it secret." Think about how many of our Ying Tianfu ...... There are at least tens of thousands of envoys from other countries, and if they learn from it, it won't be a great disaster for me. ”

Talking to him was Xu Yong, the son of Wu Kangbo, and the little guy said thoughtfully: "There are too many Yi people in Ying Tianfu, except for Dongying and the little lady of Korea, I think His Royal Highness should drive those Yi people away." ”

The other little guy said disdainfully: "You know a fart, doesn't Your Highness know it?" Only by letting the Yi people see the prosperity of my Ming Dynasty can the four Yi return to their hearts. Just by fighting, can you beat it? ”

Xu Yong smiled angrily and hugged the other party's neck, sneered and said, "Zhao Fang, you haven't practiced for a few days, you are bold!" ”

Li Zifeng hurriedly grabbed his hand and said, "Don't bully Zhao Fang, he is not in good health, and if you win, you will not win." ”

Zhao Fang was the son of Xincheng after Zhao Yi, and his grandfather Zhao Yi was the commander of Xuzhou, but he was dismissed and exiled because of killing Yun Ding and stealing military salaries.

It just so happened that he was seriously ill and did not have time to be treated, and he fell ill.

His ancestor later met the earth dragon in Luliang and turned over, and saved countless people in the catastrophe, so he was reinstated and restored to his title. However, his body has always been weaker than ordinary people.

But although Zhao Fang is not in good health, he is smart and clever, and he is a famous god operator among them.

Xu Yong was just joking with him, let go of his neck and smiled: "No matter how much you have a plan, you also want Li Zifeng to save you." ”

Zhao Fang was unconvinced: "If you have the ability, you fight with Li Zifeng, what is it to bully me, a sick man." ”

Suddenly, there was a gunshot on the other side of the school yard, which was a little deeper than the usual musket, and then a cheer was heard.

The little ones stopped talking one by one, staring curiously in the direction of the school grounds.

Li Zifeng sighed: "I don't know what the new gun looks like, if only I could shoot twice." ”

The others also nodded their heads again and again, and each one showed envious looks on their faces.

On the other side of the school field, two hundred meters away, Zhu Zhanji hit the bull's-eye with one shot, and the bullet passed through the one-inch-thick wooden target, leaving a hole.

Seeing this scene, all the nobles and generals were speechless.

Today's muskets are only lethal within 50 meters, and if they exceed 100 meters, even if they hit the vital point, they can only be injured and cannot die.

But because it was buckshot, this lead bullet entered the body, and it was eight deaths, and two more were disabled.

So today's muskets are powerful enough.

But this kind of musket, although it is only a bullet, it seems that if it hits a person, it will die!

Moreover, the distance is twice as farther.

No, more than double.

Zhu Zhanji fired a shot, and the guards of Yulinwei carried the target back to the crowd, so that everyone could see the effect of the shot.

Some people praise the gun for being good, and many people praise Zhu Zhanji's shooting accuracy.

Zhu Zhanji waved his hand, stopped everyone's discussion, and said: "If you have something to say, let's try the distance between 300 meters and 400 meters." ”

The crowd in front of them immediately dispersed, making way for a fan-shaped clearing, but they all had doubts on their faces.

These 300 meters, 400 meters, a humanoid target, it doesn't look much bigger than a soybean, can it really hit?

But Zhu Zhanji looked very sure, naturally no one touched his head at this time.

Another gunshot rang out, and everyone could clearly see that the target 300 meters away had fallen in response, and although it had not completely fallen, it was certain that the bullet had hit the target.

The guards hiding in the trench immediately got up, picked up the target, and ran back.

This time, although the bullet hit the target, leaving a hole, the bullet did not penetrate completely. The deformed bullets were mixed with sawdust, and Zhang Fu reached out and touched it, but it was burned.

He couldn't help but sigh in amazement: "Although it doesn't penetrate three hundred meters away, it can also make a big hole in a person's body." And there is also high temperature, obviously as long as you are shot, there is no luck. ”

Zhu Zhanji nodded, asked people to raise the flag again, and aimed at the target that was almost completely blocked by the crosshair four hundred meters away.

Yesterday, he had already tested many times, and it was not difficult to hit the target at two or three hundred meters, but four hundred meters away, it was completely up to feeling. After practicing all afternoon yesterday, I was able to shoot five shots at most out of ten shots.

As soon as he pulled the bolt of the gun, he withdrew a bullet case, Li Liang did not let others pick it up, picked it up himself, and put it in a pocket he specially prepared.

There were many doubts in everyone's hearts, because Zhu Zhanji fired two shots in a row, but he didn't load, but after he finished shooting, he just pulled the bolt behind him and continued to shoot.

Could it be that this gun can be loaded with multiple bullets first?

People who don't understand the separation of guns and bullets will only think it's amazing.

This kind of spear, it cannot be said which model is imitated. Because this is Zhu Zhanji's borrowing from many kinds of spear styles and making it.

In terms of reloading, he borrowed from the Mauser, who could reload five at a time, and with each shot, manually eject the cartridge case before he could continue firing.

This time, he didn't just shoot one shot, there were three more bullets in the chamber, and he shot them all at once, so that the guards could carry back the target.

This time, he performed well with three shots, and two shots should be on target.

Seeing Zhu Zhanji put down his spear, a group of nobles immediately couldn't help but come forward and wanted to take a closer look.

But Li Liang's movements were faster, and before everyone had time to get closer, he directly used a cloth bag to put the spear in it and held it in his arms.

Everyone was stunned, Yang Zhangde and Li Liang had a close relationship, and couldn't help but say: "Young Eunuch Li, why is this?" ”

Chengguo Gong Zhu Yong smiled and said: "Young Eunuch Li, Your Highness let us see the new gun, how can we put it away and do it?" ”

Li Liang said in a sneering voice: "Such a murder weapon, of course, must be kept secret. Only with His Majesty's permission can I let you see it. ”

Everyone's eyes looked at Zhu Zhanji, Zhu Zhanji nodded and said, "This is Lone's idea." This murder weapon is extremely powerful, 400 meters, or even a mile away, it can kill people, and it is necessary to prevent outsiders from learning it. ”

Everyone has a black line on their faces, this called people over, aroused everyone's curiosity, and hid the gun again, isn't this a teaser!

If it weren't for Zhu Zhanji being the grandson, everyone would have beaten him up.

Even Zhang Fu couldn't help but shake his head, clenched his fists and asked, "Your Highness, in that case, why did you call all of us and the others here today?" ”

"The British public is a little restless, and it makes sense to be alone."

One of the guards came back panting with a target, and the others stuck three targets into the ground for the crowd to watch.

On the third target, the smooth plank had two pits from deformed bullets. Although it didn't penetrate the target, it was still quite powerful.

Only then did Zhu Zhanji say: "You can see that this new musket is extremely powerful, and if it spreads, it will be difficult to prevent your safety in the future. Therefore, such murder weapons must not be circulated arbitrarily.

However, the emergence of new weapons, coupled with the fact that muskets have become more popular, has brought a problem, and my current tactics have not been able to keep up with the development of weapons.

Calling you over today, I also have a topic for you, that is, how to march and deploy in order to give full play to the role of new weapons. ”

Only then did everyone understand, but one by one they stared at the gun in Li Liang's arms, and their hearts were itching.

They are all people who have worked the battlefield for half their lives, and when they see such a weapon, if they don't study it thoroughly, where can they live!

Zhang Fu nodded and said: "When the two armies are facing each other, the main general needs to arrange his troops with all his might, make use of his strengths and avoid weaknesses on the battlefield, and give full play to his advantages. However, since the twelfth year of Yongle, firearms have been used on a large scale, especially His Highness's expedition to Dongying, the use of straggler formations, and after the three-stage strike, these two formations have become the common formations of my Ming soldiers today. However, now that the enemy has no muskets, I can win all battles in a hundred battles, and if other countries also have muskets, today's formation is indeed backward. ”

Zhu Yong said with a smile: "The British public is wrong, how can those small countries have muskets...... Europa! ”

Zheng He nodded and said: "I once went to Europe with His Highness to the sea, although there are many small countries and the power of each country is not strong, but because of the continuous fighting between each other, the development of various firearms is not much slower than my Daming. If it weren't for His Royal Highness's improvement of black powder, improved the barrel and bolt, the firearms of the firearms battalion formed by Marquis An Yuan at the beginning would not be better than the other party. ”

Zhu Zhanji nodded and said: "Now that the emperor is marching westward, you are staying in the Ming Dynasty, but you can't waste time. The development of this firearm is advancing rapidly, and the lives of our Ming soldiers are precious, so we should devote ourselves to studying how to give full play to our advantages on the battlefield. I hope you can come up with a better strategy for arranging troops. In the plains, in the mountains, in the market towns, on the river beaches, there should be different formations. ”

Everyone bowed down one after another, and Zhu Zhanji said: "Before the return of the emperor, this new gun will be kept secret for the time being, and all the technology will be sealed. When there is a better way to deal with it, it is not too late to promote the new gun, which is also for the sake of your safety. ”

"Your Highness is wise!"

These technologies have been mothballed, and the most disappointed one is Madi. Zhu Zhanji smiled, ignored him, and returned to the capital with everyone.

On the second day, a holy decree from Zhu Zhanji reached the Ma family at the foot of Fang Mountain, which immediately made the Ma family overjoyed.

Zhu Zhanji pointed out to Ma Di that he was married.

Ma Di is an absolutely alternative character in today's Daming.

In the officialdom sequence, he is just a seven-grade person, not even the main thing.

But his sister-in-law is Zhu Zhanji's Liangyuan, who is also the future national uncle-level figure.

When Zhu Zhanji ascends the throne, his reward as an earl is indispensable.

In particular, he is highly valued by Zhu Zhanji, and by his side, there are two Yulin guards to protect him all year round, which is a treatment that ordinary ministers of the fourth rank cannot enjoy.

And those who know Ma Di dare not underestimate him, not to mention the most advanced glider scout in the Ming army today, completely relying on the glider workshop controlled by him.

Just the fact that he sorted out the physics textbooks under Zhu Zhanji's arrangement and served as the director of the Gewu Research Institute can show his importance.

What's more, his uncle Ma Zhicai is now a member of the Ministry of Labor, and his father Ma Zhide is the largest imperial merchant in the Ming Dynasty, and this kind of family background is not inferior to those aristocratic families.

And his marriage has always touched the hearts of many people, such a golden beetle son-in-law, even if it is the Duke's Palace, is willing to marry his daughter-in-law.

However, when Zhu Zhanji went to sea, he took over Ma Di's marriage, and originally wanted to marry Jiaxing, but Zhang was unwilling to bear the reputation of changing relatives, so he could only give up.

Now that Madi is twenty years old, his marriage cannot be delayed any longer.

Zhu Zhanji gave this task to Sun Xian a few months ago, and asked her to choose a virtuous and virtuous cousin from the clan to marry Ma Di.

Sun Xian did not live up to Zhu Zhanji's expectations, and quickly selected more than a dozen county lords of appropriate age to be married.

And Zhu Zhanji just looked at it, and helped Ma Di determine the Kaiping county lord of Zhou Wangfu.

King Zhou is the title of Zhu Di's fifth brother Zhu Hu, and the fief is Kaifeng. He is also the brother closest to Zhu Di and has a good family style.

Zhu Hu has always studied agriculture and medicine, staying away from politics, and now Zhu Youstew, the son of King Zhou, is Zhu Zhanji's spokesperson in the literary world.

Therefore, as soon as he saw Zhu Youstew's daughter, he naturally chose Zhu Youstew's daughter, who was closest to him.

The Ma family has a simple population, rich and rivals the country, Ma Di has a simple personality and is obsessed with research, Kaiping married to the Ma family, and only enjoys happiness.

Of course, Zhu Youstew knows the importance of Ma Di, and he has also met Ma Di a few times, and he is extremely satisfied with this marriage.

Zhu Zhanji's holy decree, he also ignored the fact that it was the hottest time of the year, and returned to Kaifeng by boat to prepare for the marriage of his daughter in person.

The Ma family is also very satisfied with this family business, and King Zhou is famous for continuously publishing basic agricultural books. Zhu Youstew is also one of the few representatives in the clan who can hold real power, and the Zhou Wangfu has a close relationship with the royal family, and this family affair is impeccable.

In order to prepare for Ma Di's marriage, Zhu Zhanji gave the Ma family a set of courtyards in Xiamaqiao, which was a set of quiet courtyards built for him by the Ministry of Industry in order to appease him when he was originally building Xiamaqiao Farm.

This annex is not only in a good location, but also in a good environment, and every brick and wood is made by the royal family.

But because the Xiama Bridge was too close to the palace, Zhu Zhanji never lived there once, and it was empty for several years.

Zhu Zhanji gave him this house, which can be regarded as making the best use of everything.

Of course, because it is an imperial specification, this set of courtyards is awarded to him, and it needs to be renovated, such as the regulation of the gate to be changed, and the original main hall must also be separated separately, and it cannot be rewarded to Madi.

Otherwise, he would not dare to ask for a house regulated by the royal family.

Even so, just the courtyard where people live in the back is larger than the average public family.

Zhu Zhanji made such a decision, and everyone saw his preference for the Ma family.

But he didn't expect it himself, just because of his love for Madi, many young people have a greater interest in Gewu.

The second brother is getting married, Ma Xin is naturally very happy, these days, he personally brought a group of chamberlains and palace maids, and negotiated with the people of the Zhou Wangfu to decorate the second brother's new home.

Marriage in this era is definitely not the affairs of the man's family, for example, the man's family prepares a new house, and the woman's family has to make furniture.

How big the house is and how much furniture to be made, this requires communication between both parties, and Ma Xin's identity is perfect for this.

(In the past two days, I have been visiting relatives, and my thoughts are complicated, and this chapter is not very smooth.) Now I owe you a more, I try to make it up as soon as possible)
