I do research in ancient times

What Qiongzhi was talking about was the arsenal that Ning Fei was planning to build, specializing in the manufacture of coastal artillery and shells.

When it comes to confidential military information, the craftsmen inside will naturally not be recruited from outside, and all of them come from the craftsman's house set up by the frontier army.

But the mining and processing of raw materials is not something that needs to be kept secret, and half of the skilled hands are enough to do it.

Just like what Ning Fei said to Brother Mu Ye before, you can’t leave everything to the frontier army. The frontier army has to defend the city, farm the fields and fight against the barbarians. How can they have so much energy.

Appropriately releasing some unimportant resources to the people to drive the development of surrounding industries and supporting facilities is the right way for the industry to sustain itself for a long time.

Ning Fei is now worried about steelmaking.

The purity of iron ore in Niubei Mountain is average, so it is not a problem to forge cold weapons, but if you want to forge cannon barrels, there are congenital deficiencies there.

Modern gun barrels are made of alloy steel.Due to the extremely high instantaneous pressure and extremely high temperature generated by the barrel when the gun is fired, only high-strength alloy steel with trace elements such as carbon, nickel, chromium, and platinum can meet the requirements.

Although modern technology standards can be appropriately lowered, elements harmful to the strength and toughness of artillery such as sulfur and phosphorus must still be removed.

Ningfei thought about this all night, and got up early the next day and ran to the industrial area to call his two proud little assistants out to discuss steelmaking.

However, Liu Tong didn't know metallurgy, so he couldn't help much in the casting of the cannon body, so the task of making the cannon body for the first time fell on Liu Tie and his senior brother Xu Jin.

"To make such a steel cylinder, I have marked the dimensions on the drawings. First, you can make one according to the current steelmaking method and let me have a look."

"There is an important point for you to pay attention to. When processing molten iron, you should add more limestone to remove impurities, otherwise it will affect the toughness of the finished product. Afterwards, the steel wire is tightly wound on the gun barrel. The finer the better, try not to leave any gaps."

Ning Fei handed over the results he drew all night to the two, and told them all the questions he could think of, but he still felt unsure.Originally, he wanted to ask Nada, a craftsman from heaven, to make cannons together, but Nada is still learning Yechao Mandarin, and he is not familiar with the disciples of the blacksmith workshop. Joining the team rashly may cause problems of running-in.

In fact, he is not sure whether the current steelmaking method can produce suitable gun body steel. After all, he has jumped from a cold weapon to a hot weapon. If this step is not done well, it may be a mess.In this era, apart from him, Ning Fei, no one has a concrete concept of such things as shore artillery. Without the aid of equipment to detect, then we can only let the facts speak for themselves. Once the shells are fired, we will naturally know the body of the gun. How is the quality.

However, firing cannonballs is not a trivial matter. If one is not careful, the incident of the Niubei Mountain Skyfire and Thunder will repeat itself.

No one knew about Ning Zazi's uneasiness.After five days of fear, the first cannon in Mozong's history finally appeared.

The cannon-making trio were all satisfied with the results.It took them a few days to make this thick cylinder, and it took a day and a half to wrap the steel wire. All the dimensions were strictly in accordance with the requirements of the moment, and there was no slight difference.

I thought that I would be praised by Juzi, but the young man who came to check and accept had a serious expression on his face, and there was no relief in his brows.

After nodding his head, Ning Juzi talked about the cannonball again.

The steel used for shells requires high strength and high hardness, and a certain fragmentation rate under the action of explosive loads.But shells are also consumables, and the cost should be suppressed as much as possible. The focus is on workmanship, and the requirements for craftsmen's skills are very strict.

At present, the shells can only be filled with black powder, the safer, more stable and more powerful trinitrotoluene, which is stranded because it is temporarily impossible to extract crude benzene from the coke oven, but the nitroglycerin used to launch gunpowder, Ning Juzi has already advanced Ready.

While the craft team was busy making cannonballs, Ning Zazi carefully inspected the cannon barrels they made.

It has to be said that the creativity of craftsmen is endless.Even without the aid of various modern large-scale equipment, Liu Tie and Xu Jin tried their best to restore his design drawings. At least from the appearance, this is already a formed gun barrel.

The design of the shore artillery is rather based on the Hongyi cannon.The barrel of the Hongyi gun is long and thick, and gradually thickens from the muzzle to the tail, which is in line with the principle that the chamber pressure changes from high to low when gunpowder burns.

There are lugs cast on both sides of the center of gravity of the gun body, and the gun can adjust the shooting angle based on this axis, and change the firing range according to the amount of gunpowder.As long as the parabola is calculated accurately, a higher accuracy of the ballistic can be achieved.The length of this cannon trial-produced by Ning Fei is about two and a half meters, and the caliber is 80-100mm. It is shorter than the normal Hongyi cannon, but the self-tightening technology is installed on the cannon body to prevent the chamber from exploding. The estimated range is six to seven miles. Left and right, using a rack-back type front-loading smoothbore.

However, this design also has disadvantages, that is, every time it is fired, it will seriously deviate from the shooting position, and it is necessary to assist the gunner to reset and reload, and reset the azimuth and elevation angles.However, compared with the front-mounted artillery, the Hongyi Cannon knows that skilled operation can still quickly form combat power. Now it depends on whether the craftsmanship can realize the design intention.

A day later, the cannon came out of the furnace, and Ning Juzi led the team, pulled the cannon, and found an open wasteland to conduct experiments.

Naturally, it was impossible for him to complete the launch by himself, so he found a few more helpers, and the iron fan Twelve Lang was among them.

Ning Fei didn't want to take him with him at first. After all, testing the gun is risky. He had been worried about the bombing accident before, and it was really dangerous for Twelve Lang to follow.

But he couldn't hold back the child, and swore with his father and his elder brother that he would stay aside and not make trouble, so Ning Fei just let him go.

He intends to let the Feng family be a witness, after all, the future materials of this cannon will be produced by the Feng family's Liushan Mine, so we have to show our partners the research results.Moreover, the safety zone of this experiment is set far away, as long as you don't run out, there is no danger.He also made an agreement with Twelfth Lang that he could only watch from a distance in the safe area, and no matter what happened, he couldn't get close to him, and he hired two disciples to supervise.

"Put this in your ear, it'll be loud in a while."

Before the start, Ning Fei began to distribute cotton earplugs to the three people in the safe area, emphasizing safety discipline again, with a very dignified expression.

Twelve Lang was a little scared.

He had never seen such a serious brother Fei.

For a moment, he even felt that the person standing in front of him was the big beast in his family, so he couldn't help but wince and nodded obediently.

"Okay Brother Fei, I will be obedient and I will never run around."

Hearing what he said, Ning Juzi nodded with satisfaction, touched an object from his arms and handed it to him.

"There are rewards for obedient children. Let me lend you this one to play for a day."

Twelve Lang took it over and looked at it, his brows were filled with joy, and he nodded hurriedly.

"Okay, okay, okay!"

What Ning Fei handed over was a small telescope, which was much smaller than what he had seen from his elder brother before, but the functions were exactly the same!

Brother Xiaofei must have lent him his clairvoyance because he was worried that he could not see clearly. Brother Xiaofei is such a kind person!

Watching his beloved brother Fei go to the test site, Shi Shilang squatted on a slope in the safe area and looked around.

The test site is located in a wasteland on the east side of Jiuling Lake, far away from farmland and workshops. I heard that Juzi will be doing experiments today, and Jiuling City informed all staff not to approach the test area early in the morning. Violators will bear the consequences at their own risk.

With the lesson of blood and tears from Tian Huo Lei, the disciples of Mo Zong will naturally not cross the line.The focus is on those workers and students who entered the city later. The weaving workshop and the school are all assembled today. During the period of Juzi's cannon test, no one is allowed to leave the workshop.

For a while, the atmosphere was a little tense, and some young female workers who had just entered the city were very frightened.

"nothing."

Granny Qiu patted the arm of a young female worker.

"There are a lot of rare things in our city, and they are all made after such a little bit of thinking."

"Since the Zongmen said to let everyone avoid it, it will be absolutely fine if you are obedient. Trust me."

"I'm not afraid."

The young man raised his head, and it was Qiongzhi, the granddaughter of Lao Juntun.

"Grandma Qiu, I know that Mo Zong is a good person, and it is impossible for him to harm me. Only Jiuling City in the world can give a country girl like me a new way to work to support myself. Now I feel at ease."

Qiong Zhi said seriously.

"Right now, I'm afraid that someone will harm Mo Zong and Jiuling City. In a few days, it will be my turn to rest. If something really happens, then I won't go back. I will fight those bad guys!"

Hearing what she said, Granny Qiu was amused, and reached out and tapped the girl's forehead.

"Don't talk nonsense! Ning Juzi is very powerful and won't let anything happen to the sect."

"Even if there is such a day, it will not be your turn, little ladies. There are still a lot of young people in the city."

"It's time for you to rest and take a shower. Go back, rest and go back to work. Putting those wool to good use is better than anything else."

Just as she was talking, Granny Qiu heard a loud noise in her ear.

Bah——!

The sound came from outside the city, and it was so loud that the earth trembled.

The people in the city were a little panicked, they instinctively wanted to oppress and run away, looking for a safe place to hide.

Fortunately, people are now concentrated in a few workshops. After the initial shock, the disciples responsible for maintaining order quickly stabilized everyone's emotions and controlled the situation as quickly as possible.

"it's okay no problem!"

Hasler panted and ran in from outside, shouting while shaking his arms.

"Juzi is studying Leihuo, it's fine."

Oh, it turns out that Juzi has gone to make thunder and fire again.

Mozong disciples heaved a sigh of relief when they heard the news.

That's right, it's Leihuo, that thing is loud, no wonder it makes the ground tremble.

The new students and female workers in the city didn't understand. Someone asked a familiar disciple of Mo Zong to inquire about the situation. Although they couldn't understand what the other party was talking about, they knew that it was Mo Zong's handwriting. Apart from being shocked, they felt admiration born.

Scary, it's really powerful, even thunder and fire can be created, could this Mo Zong's Juzi be a little fairy?

It's just that the people in the city only heard the sound and didn't see the scene. It was far less shocking than witnessing the launch of the shore artillery.

Brother Feng's legs were trembling, and he sat slumped on the high slope motionless, limp and without any strength.

In his hand, the beloved Qianlimu rolled to the side, only half an arm's distance away, but it seemed so far away, no matter what, he couldn't reach it.

The weight of his whole body was on his arms, and he was afraid that if he moved a little, the barely maintained balance would fail.

Just now... the one just now... is... what is it?

Xiaodi Feng was still in shock, and his mind kept replaying the miraculous scene he saw through the clairvoyance.

His little brother Fei walked down the high slope, got on his horse, and went to the strange cylinder placed in the wilderness.After he arrived, the few Mozong craftsmen who were still gathered together suddenly dispersed, and only Brother Xiao Fei was still standing there, sorting out something.

Brother Xiao Fei also left later, but he didn't go very far, he turned around and pulled the rope directly.

Next...

Brother Feng swallowed, and once again suspected that something was wrong with his eyes.

He saw that a big iron ball suddenly spewed out from that big barrel, and the huge force knocked the barrel back several steps!

Then the iron ball, seeing it hit a hill, made a loud "bang", and the rocks were blown to pieces!

It was broken... The stone was really broken... The broken loess filled the sky, and the huge sound directly shook him to the ground.

Brother Feng swallowed.

If he hadn't been so frightened that his limbs became weak, he really wanted to rush over to ask Brother Xiao Fei immediately.

This... what kind of fairy weapon is this...?
