The Ming Dynasty started with caution

Emperor Hongzhi and Li Dongyang and others looked strange.

The first thing Yan Chengjin did when he entered the Beijing Camp was to give out silver. This was not difficult to understand. The soldiers of the Beijing Camp had not received Yuexiang for a long time. This move was to restore the soldiers' trust in the court.

But now that Yuexiang had been issued, why did he need silver again?

Before Emperor Hongzhi asked, Yan Chengjin said, "Most of the firearms and other equipment in the Beijing Camp are old, and many need to be replaced. Please grant your approval, Your Majesty."

Emperor Hongzhi understood that he had to spend money where it counts, so he said, "Order the Ministry of Works to supervise the production, but remember, save as much as possible."

The cost of manufacturing armaments has always been high.

What's more, there are more than 50,000 people in the Beijing Camp. How many weapons should be prepared? Emperor Hongzhi felt a dull pain in his heart. He was ready to bleed heavily. If the treasury was insufficient, he could only use the money from the inner treasury.

The Beijing Army is the foundation of the country!

After coming out of Fengtian Hall, Yan Chengjin came to Wanggongchang of the Military Equipment Bureau because Song Jing was here.

With the relationship with Teacher Zeng Jian, Song Jing was very convenient here as a craftsman, and the craftsmen all called him Master Song.

Emperor Hongzhi issued an edict, ordering the Ministry of Works to supervise the military equipment of the Beijing Army, and Zeng Jian also rushed to Wanggongchang in person.

"My dear nephew, tell your uncle which cannon you want to build."

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

When Song Jing saw Yan Chengjin, he bowed and said: "Student greets adults."

"These cannons cannot be used, and they need to be improved."

The surroundings suddenly became quiet.

The craftsmen of Wanggongchang looked strange.

The Weiyuan General who fought in Weiyuan had a range of nearly four miles, which was the most powerful cannon in the Ming Dynasty.

Zeng Jian's old face twitched: "My dear nephew, this is the most powerful cannon in the court now."

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

After Song Jing's transformation, the Weiyuan General has a range of more than three miles, and the increased power is amazing. How can it be unusable after just one use?

Song Jing was dumbfounded and didn't say anything. After coming to the capital, he was cheated of a lot of money and no longer dared to trust others easily. He only believed Yan Chengjin because Yan Chengjin had never cheated him of money.

"Do you think there is still room for improvement?"

In the early Ming Dynasty, people liked to call artillery generals.

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

But the Weiyuan General was much worse than the French cannon and did not surpass the West.

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

Such artillery would be sunk by the Portuguese if it went to sea. At this moment, the Portuguese entrenched in Malacca were equipped with early French cannons.

The only one who could surpass the French cannon was the red barbarian.

When observing politics in the Ministry of Industry, Yan Chengjin learned to draw blueprints. Although he was not very good at it, he was able to draw a rough blueprint of the Red Cannon.

The gun barrel and other parts of the Red Cannon must be in a certain proportion to exert their power.

The length of the barrel is about 22 to 28 times the caliber.

The thickness of the muzzle wall, the length of the gun ears, and the diameter are the same as the caliber.

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

The rest is the gunpowder recipe, which has two recipes: horizontal explosion and vertical explosion. The main gunpowder for horizontal explosion is saltpeter, nine-tenths of saltpeter, and one-tenth of sulfur.

For horizontal explosion, saltpeter accounts for seven-tenths and sulfur accounts for three-tenths, and charcoal is burned from trees such as poplar and dead fir as auxiliary materials.

"Try it according to this blueprint. Make five guns within 20 days. If the range of the gun does not reach more than eight miles, all of them must be redone."

Eight miles?

Zeng Jian and the craftsmen gasped.

You are here to mess things up, right?

Zeng Jian held up two fingers and asked with a smile, "My dear nephew, what do you think this is?"

"Two!"

Zeng Jian almost jumped up and cursed angrily, "You still know this is two! Eight li? Can eight li be made? I have been an official for more than ten years, and I have never seen anyone as pretentious as you!"

General Weiyuan is only three li, and you want to increase it by two times in one breath. Do you think this breath is fairy air?

If someone else said such a thing, Zeng Jian would slap him a few times and throw him out of Wanggongchang.

But Yan Chengjin, he still left some face.

How could Zeng Jian learn the words to scold Zhu Houzhao...

Yan Chengjin's face suddenly darkened.

Seeing that his face was not right, Zeng Jian thought that he had scolded him too harshly, and said angrily: "My dear nephew, I think that an increase of one mile is a good omen."

Yan Chengjin gave him a weak look. He was so embarrassed to call such a short range a good omen.

Song Jing said solemnly: "Master Yan said it is possible, 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 seriously.

This is the attitude of doing scientific research.

After bombing Wanggongchang, this guy seemed to be calmer and more restrained.

Zeng Jian glanced at the paper. There were only three cannons drawn, but it was actually one cannon, divided into the front, left, and top.

Just based on this piece of paper to increase five miles?

"My dear nephew, don't blame me for not reminding you. It takes a long time to make a cannon. You said eight miles, but it may not be made in twenty days." Zeng Jian said.

Yan Chengjin nodded.

Beijing Military Training Ground,

Wang Shouren trained the soldiers in the barracks and thought about the training method. He sat there for a day and a night thinking hard.

After the moon sound, the morale of the soldiers was greatly boosted, and they were like two different people. The shouts on the parade ground shook the sky.

Zhu Houzhao asked Wang Hua for sick leave and ran to the parade ground. He thought that Wang Shouren, a fool, would not train the soldiers. Who knew that he was doing it well? Suddenly he felt very uncomfortable.

"As a military supervisor, Lao Gao did not train the soldiers in the Beijing camp. It's really hateful."

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

At this time in Shijingshan, Xu Jinzhong led a group of lieutenants and strongmen from the Tuntian Camp to open up the land and do carpentry. They built a high platform here, cleared the weeds, and opened up a flat land.

The location of the Beijing camp could not be exposed, so the place where Hongzhi hunted was decided here.

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

These days, Xu Jinzhong led the Tuntian Camp to set up here.

"Everyone work hard, just by planting a field, we can get four coins of silver, where can we earn it, you can just laugh secretly." Xu Jinzhong forced a smile on his face, but his heart was bitter.

The 12th regiment of the capital, from occasionally farming, to farming for generations.

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

The heads of dozens of thousand households and hundred households were like big watermelons, and they were cut off at will.

"I remember your name is Xu Jinzhong, you did a good job!"

Yan Chengjin heard the familiar voice and looked up. Zhu Houzhao, the dog, was standing with his hands behind his back, like a leader inspecting, in a proper manner.

"Your Highness ran out of the palace again?"

Zhu Houzhao came over with a smile: "This is not the first time for me. If my father doesn't beat you, why are you panicking."

Yan Chengjin shook his head.

It's okay on weekdays, but now envoys from various countries have been invited to watch the ceremony. If you are killed and thrown into the ravine, there will be no more trouble.

"Your Highness, bring a few more Jinwu Guards with you next time you go out. The capital is not safe now."

"They will follow me, otherwise how can I report my movements to my father?"

Yan Chengjin felt that it was useless to say anything, so he decided to ask Mou Bin to send more people to protect this guy.

Xu Jingzhong came over and said with a smile: "Sir, this high platform is almost built. Next, can we go back to the Beijing camp?"

"No, we have to start rushing to build a high wall according to the standard of the city wall."

"What do you want to build a wall for, sir?"

"Lao Gao, why do you want to build a wall? Do you want to show the envoys the wall-building technology of the Ming Tuntian Camp?"

"Your Highness is really smart. Building a wall is to show the defensive power of the military force."

Xu Jinzhong's mouth twitched fiercely, and he turned around and led his brothers to build the wall again.
