"I've done it!" The fat grain merchant who was like a rich man looked gloomy and gloomy, and finally gritted his teeth and said harshly.

As he said that, he looked up at Chen Jie and said, "Mr. Chen, do you remember what you said..."

"Although my family is not a very large family, it is not easy to be humiliated! If the Zhang family fell down, what you said cannot be fulfilled..."

Chen Jie did not avoid the rich man's gaze, but instead met him straight: "The head of the neck is allowed to be taken!"

After hearing this, the grain merchants couldn't help but agree, saying that how could I miss my husband in such a grand act?!

Let’s ask Mr. Chen to make arrangements, and I am willing to follow Mr. Chen’s horses at the end!

Then Chen Jie smiled indifferently and began to give me instructions to do this.

What no one knows is that Chen Jie's sweatshirt behind him is already wet...

Of course, Chihu'er didn't know that the grain merchants are now gathering up and plotting against him, plus his industries that make people envious of money every day.

Even if he knows...if you know, then you know. What will the cat do when the mouse is going to plot against him?!

I still ate him. Are you talking about the prey you are talking about?!

You hold a mountain-opening axe and your opponent holds a small toothpick, and everyone stands face to face, and you are still telling him about Mao’s strategy!

Chihu'er is now in the foundry department of the Ordnance Construction Bureau, watching the casters pour the melted copper juice from the crucible into the mold "gulp~".

"Sizi ~~" The air holes in the mold kept spraying out rich poison gas, but this huge mold had been placed underground.

The crazy tiger blinked his beautiful pair of phoenix peach blossoms, and admired the wisdom of these ancient craftsmen in his heart.

They only mentioned the casting process a little, but after refining more than 10,000 kilograms of copper ingots, they really found the most suitable casting model.

They first used it to dig on the ground and built huge cooling holes.

There are multiple exhaust ports in the pothole linked to the outside to vent hot air, and there are steps to reach the bottom of the pothole.

Then, a huge base was built and hung into the pothole, and then a huge mosaic shell mold was created by the steel filling method.

The entire inner shell and inner liner mold were cast. The original clay mold was obtained by obtaining the sand mold and oil mold provided by Chihuer and mixed proportions.

The mold is made by the model method first. After the two are fixed, the inner shell is pulled out and the inner shell is molded.

The whole is mounted on a compacted base, pour melted copper juice into the holes reserved in the shell for casting.

One of the achievements obtained by refining more than 10,000 kilograms of copper ingots was that they confirmed the best mixing ratio of mud, sand and oil at present.

The advantage of model manufacturing is that every time the mold is made, you only need to mix oil sand mud, and then compact and mold it with the mold to cast.

At least the cannons cooled after infusion of copper in the previous experiment were tightly integrated, without pits and without gaps.

The barrel was smooth and tidy and without trachoma, and the hole was holed. It was tested and fired at 150 guns, and there was no problem in firing ten guns in a row at a maximum of 10 guns.

What was cast today was the fifteen-inch cannon that had just been produced, and this trip was the biggest one they had played.

The direct material is a total of 13,000 kilograms of copper ingots. If you use it, you will lose the 13,000 kilograms of copper ingots.

"Sizizi..." In the cellar under the cement slab, the mold air holes kept spraying out huge heat.

Even through the ground, I could feel the high temperature coming from the underground.

Several old craftsmen with many years of casting experience looked at the infusion process nervously, and even if they were hot, they would not dare to separate them.

As the last bit of copper juice was poured in, everyone knew that all they could do was wait.

It takes time for casting cannons to cool down naturally, and everyone can only choose to wait for this time.

It is naturally impossible for the young master to come to this foundry just because of the casting cannons, but also because of the newly built shells from the casting cannon factory.

The heavy cannon used by Europa was stone bullets, and the Ming craftsmen who received enough money and had a lot of supplies to consume were all kinds of ideas.

They first weighed stone bullets of the same diameter and size, and then made molds of the same size.

Then roughly calculate that the same weight of sand steel and oil sand mud are wrapped with thick sand steel with the outer layer of oil sand mud as the core.

The size of the shell reaches the size of the stone shell, but it is lighter, has a longer range and has stronger lethality.

The most important thing is that the shells will explode after flying to the target and the splashing fragments and oil sands will cause large-scale damage.

"Bang bang bang bang bang bang bang bang bang bang bang!"

The young master looked at the city wall in the distance and directly exploded a huge gap!

Emperor Hongzhi, who was beside him, was excited and turned red.

Zhu Fu, the Duke of Chengguo, was also stunned when he saw this. No wonder the schoolyard was banned from more than ten miles away.

How can such a powerful weapon be easily shown to others? It must be banned.

Chen Tong rumbled on his war horse and ran over quickly, and took back the straw dummies in armor.

But the armor on the straw dummies was broken into pieces, and the splashed pieces directly shattered the armor and penetrated into the dummy.

The hot oil sand mud raised the armor even more concave and convex. I'm afraid that real people can't withstand this huge impact even if they are worn by them.

"Okay!!" After burning tens of thousands of kilograms of copper ingots in, he finally saw the results.

Emperor Hongzhi was so excited that he turned around and patted the young master on the shoulder and said, "The country's weapon is very good!!"

"If His Majesty had handed over the fireworks craftsmen to the boy earlier, I'm afraid the cannon medicine of the state would have been up long ago..."

Chihu'er blinked his pair of elixir peach blossoms and curled his lips: "There are so many smart craftsmen, but His Majesty is really a waste of using them for fun!"

Emperor Hongzhi said this and his face turned red. It was not his first creation to summon fireworks to make fireworks.

Since the Song Dynasty, this has been one of the royal habits, and gathered excellent folk firework craftsmen to make firework entertainment in the palace.

Many of these fireworks are studied by people, how to make fireworks look good and enjoy.

From the Song Dynasty to the present, neither the official nor themselves have thought of using their research for military purposes.

When Chihu'er first learned from Zhu Houzhao that there were these fireworks craftsmen in the palace, she almost burst into anger.

A group of pig heads! How come you never thought about letting them improve gunpowder for cannons and muskets?!

The group of people were brought over in a sad and anxious manner, and the first thing they received was the Anjia of twenty taels per person.

Miao Kui was familiar with them, so he was ordered to come over to comfort him: From now on, everyone will make five cents a month, and they will also be rewarded as required!

Don’t keep the secret recipes of each family. If you do well, your children will go to school and solve the food and fodder at home!
