Emperor Hongzhi and Li Dongyang and others had strange faces.

The first thing Yan Chengjin did when he entered the Beijing camp was to issue silver, which is not difficult to understand, the soldiers in the Beijing camp have not received the moon for a long time, and this move is to reinvigorate the trust of the soldiers in the imperial court.

But now, the moon has sounded, why do you want silver?

Before Emperor Hongzhi asked, Yan Chengjin said: "Most of the firearms and other equipment in the Beijing camp are outdated, and many need to be replaced, and I ask Your Majesty for permission." ”

Emperor Hongzhi knew in his heart that he was going to spend the silver on the blade, so he said: "Order the Ministry of Engineering to supervise it, but remember, if you can save it, you will save it." ”

The cost of manufacturing armaments has never been low.

What's more, there are as many as 50,000 people in the Beijing camp, so how many weapons do you have to prepare? Emperor Hongzhi felt a faint pain in his heart, he was ready for heavy bleeding, and if the treasury was insufficient, he could only withdraw from within.

The Beijing army is the foundation of the country!

Coming out of Fengtian Palace, Yan Chengjin came to Wang Gongchang of the Ordnance Bureau, because Song Jing was here.

With this relationship with Teacher Zeng Jian, it is very convenient for Song Jing to be here as a craftsman, and the craftsmen call him Master Song.

Emperor Hongzhi issued an order to supervise the preparation of the Beijing army, and Zeng Jian also rushed to Wang Gongchang in person.

"Virtuous nephew, tell Shibo which artillery you want to build."

Yan Chengjin shook his head: "Call Master Xiao Song." ”

When Song Jing saw Yan Chengjin, he arched his hand and said, "The student has seen the adult." ”

"These guns are no longer usable, and they need to be improved."

There was a sudden silence.

The craftsmen of Wang Gong's factory had strange faces.

In the Weiyuan War, General Weiyuan, with a range of nearly four miles, is currently the most powerful artillery in the Ming Dynasty.

Zeng Jian's old face twitched: "Virtuous nephew, this is the strongest artillery in the imperial court now." ”

The power of firearms is measured by their range, and the power of General Zhankou is only half a mile.

After Song Jing's transformation, General Weiyuan's range has reached more than three miles, and the power of the increase is amazing, why can't it be used after only one use?

Song Jing didn't speak in a daze, after coming to the capital, he was cheated of a lot of silver, and he didn't dare to trust others easily, but he only believed in Yan Chengjin, because Yan Chengjin had not deceived him of his silver.

"Do you think there's still a chance to improve?"

At the beginning of the Ming Dynasty, he liked to call artillery generals.

Yan Chengjin knew that in Zeng Jian's cognition, General Weiyuan was already a very powerful firearm.

But General Weiyuan is much worse than the Furlong cannon, not more than the West.

As the ancestor of gunpowder, how can he let his grandson surpass.

If such artillery goes to sea, it will also be sunk by the Portuguese, and the Portuguese who are entrenched in Malacca at this moment have been equipped with early Furlong cannons.

The only one who can surpass the Furlong cannon is Hongyi.

When he was in the Ministry of Industry to observe the government, Yan Chengjin learned to draw drawings, although not very deep, but he could also roughly draw the drawings of the Hongyi cannon.

The body and other parts of the Hongyi cannon must be in a certain proportion in order to exert its power.

The length of the barrel is probably twenty-two to twenty-eight times the caliber.

The muzzle has the same wall thickness, lug length, diameter and caliber.

The shape gradually thickens from the muzzle to the tail of the gun, and the thickness of the pipe wall is extremely thick, so that it is not easy to explode.

The rest is the gunpowder formula, there are two kinds of prescriptions for horizontal explosion and longitudinal explosion, the horizontal explosion is mainly gunpowder is saltpeter, nine-tenths of saltpeter, with one-tenth of sulfur.

Horizontal explosion, saltpeter accounts for seven-tenths, sulfur accounts for three-tenths, and then poplar, withered fir and other trees are burned into charcoal as auxiliary materials.

"Try according to this drawing, within 20 days, make five guns, if the range of the cannon can't reach more than eight miles, all of them will have to be redone."

Bali?

Zeng Jian and the craftsmen gasped.

You're here to smash the field!

Zeng Jian stretched out two fingers and asked with a smile: "Virtuous nephew, what do you think it is?" ”

"Two"

Zeng Jian almost didn't jump up, and scolded angrily: "You still know that this is two!" Bali? Can Bali make it, the old man has been an official for more than ten years, and I have never seen someone like you who can pretend to be a beep! ”

General Weiyuan is only three miles, and you have to increase twice in one breath, do you think this breath is immortal?

If someone else said such a thing, he would be slapped a few times and then thrown out of Wang Gong's factory.

But Yan Chengjin, he still has a little face.

If you scold Zhu Houzhao, how can you let Zeng Jian learn......

Yan Chengjin's face suddenly darkened.

Seeing that his face was wrong, he wondered if he was scolding too much, Zeng Jian was busy and said stupidly: "Virtuous nephew, the old man feels that if he improves one mile, it will be auspicious." ”

Yan Chengjin glanced at him weakly, such a short range is embarrassing to call Xiangrui.

Song Jing said solemnly: "Lord Yan said yes, there must be a reason, and the student is willing to give it a try." ”

Whenever he told Song Jing something incredible, he always took it so seriously.

This is the attitude of doing scientific research.

After blowing up Wang Gong's factory, this guy seems to be more calm and introverted.

Zeng Jian glanced at the piece of paper, and only drew a three-pole cannon, but it was actually a cannon, which was drawn on the front, on the left, and on the top.

Just rely on this piece of paper to improve five miles?

"Virtuous nephew, don't blame the old man for not reminding you, the time to make a cannon is not short, you said eight miles, and it may not be possible to make it in twenty days." Zeng Jiandao.

Yan Chengjin nodded.

Beijing Military Academy,

Wang Shouren trained the soldiers in the barracks, and wanted to practice the method, so he meditated and sat for a day and a night.

After the moon sounded, the morale of the sergeants was greatly boosted, and if the two of them were judged, the shouts on the school field shook the sky.

Zhu Houzhao asked Wang Hua for sick leave, and ran to the school field, thinking that Wang Shouren, a fool, could not train soldiers, but who knew that there was still a decent person, and suddenly felt very uncomfortable.

"Lao Gao, as a prison soldier, is not training in the Beijing camp, which is really hateful."

learned from Wang Shouren that Yan Chengjin went to Shijingshan, and suddenly smelled the smell of conspiracy, and he hurriedly came to Shijingshan.

At this time in Shijingshan, Xu Jinzhong took a group of captains and wrestlers from the Tuntian camp to reclaim and do carpentry, build a high platform here, clean up the weeds, and open up a flat land.

The location where the Kyoying camp was stationed could not be exposed, so the place where Hongji hunted was set here.

The high platform was used for the Hongzhi Emperor and the envoys to observe the ceremony.

These days, Xu Jinzhong took the Tuntian camp to build here.

"Everyone work hard, just by planting a field, we will have four dollars of silver, where to earn it, you can laugh secretly." Xu Jinzhong had a strong smile on his face, but he was bitter in his heart.

The 12 regiments in Beijing camp thousands of households, from occasional tuntian, to generations of tuntian.

But he didn't dare to show it, Yan Chengjin was staring at it from a distance.

The heads of dozens of thousands of households, like big watermelons, are cut when they are said.

"This palace remembers that your name is Xu Jinzhong, and you did a good job!"

Yan Chengjin heard the familiar voice, and looked up to see that Zhu Houzhao was holding his hands behind his back, like a leader inspecting, looking like a leader.

"Your Highness ran out of the palace again?"

Zhu Houzhao walked over with a smile: "It's not the first time in this palace, my father doesn't beat you, what are you panicking about." ”

Yan Chengjin shook his head.

It's fine on weekdays, but now that I have invited envoys from all over the world to watch the ceremony, I will slaughter you and throw you into the ravine, and you will never suffer from it.

"Your Highness will come out next time, bring a few more Jin Wuwei, now the capital is not safe."

"They will follow the palace, otherwise how to report the movements of the palace to their father."

Yan Chengjin felt that what he said was in vain, so let's let Mu Bin send more people to protect this guy when he goes back.

Xu Jingzhong walked over and said with a smile: "My lord, this high platform is about to be built, next, can we go back to Beijing?" ”

"No, we have to start working in a hurry, and build a high wall according to the standards of the city wall."

"What do you do building a wall?"

"Lao Gao, what are you going to do to build a wall, you want to show the envoys the wall-building techniques of the Daming Tuntian Camp?"

"Your Highness is so clever, building a wall is a garrison force in the display of military power."

The corners of Xu Jinzhong's mouth twitched fiercely, turned around and led his brothers to build a wall again.
