After arranging the production process of the musket, Lu Zhan took Duan Xiaohan to the school he opened.

"Lord, what is taught here is different from what I learned in Dingtao before, in addition to teaching questions, I also teach arithmetic and painting."

Lu Zhan shook his head, sure enough, most ancient people's thinking was still different from that of modern people, "Xiaohan, have you ever heard of the term teaching according to aptitude, not everyone has to learn articles and full of benevolence and morality, some people who are proficient in arithmetic can be mathematicians can become businessmen, and people who like to draw may become good materials for artists or draftsmen." ”

"What the lord said is indeed reasonable, the child who came out of this school will definitely be the pillar of Yanzhou in the future, and the lord of your shares." Duan Xiaohan looked through the window at the students who were fiddling with abacus beads and flipping through classic ancient books.

In this era, it is a rare opportunity to enter the school to study, and these children cherish this opportunity to read so much. If I could have such a motivation to study when I was in school, I might be a student of a double first-class university.

After leaving the school, Lu Zhan saw the hens in the fence circle not far from the school, these are the experimental grounds for students who like to raise chickens and farm in the school, after all, agriculture is the foundation of everything. Farmers and breeders from all over Yanzhou used these fields for these students to experiment.

"My lord? How do you look at these fences and get distracted. Duan Xiaohan looked at Lu Zhan's face with a smile in confusion.

In Duan Xiaohan's opinion, what is so beautiful about these fences and hens, it can't be that the lord is greedy and wants to eat the old hens.

"Lord, don't look at it, just let Xiao Yezi stew a pot of old hen soup for you when you get home."

"What's the matter, who's going to eat the old hen. I'm looking at the fence. Walk! Now come with me to the blacksmith shop in the cottage again. Lu Zhan said as he mounted his horse and rode away in the direction of the villa.

Although Duan Xiaohan didn't know what Lu Zhan meant, he still followed, "I'm afraid I won't be able to go back to Yanzhou City at night if I go to the villa now." ”

"It's okay, there's something more important for me to go to now."

After Lu Zhan and Duan Xiaohan came to the blacksmith shop in the villa, many blacksmiths stopped their work and looked at Lu Zhan who had returned.

Lu Zhan once again showed his level of painting, and several blacksmiths gathered around to see that the drawing was a wall formed by several wires entwined together.

"Masters, I am now going to select a group of people to forge barbed wire, forging these requires drawing steel into a wire shape, in order to facilitate the use of soldiers, these wires need to be both strong and tough, and the master who can do these crafts stands at the gate."

With Lu Zhan's order, seven or eight blacksmiths who were confident in their craftsmanship were occupied, and these blacksmiths gave up the work of forging the barrel and turned to the manufacture of barbed wire.

After leaving the blacksmith shop, looking at the sky that had gradually darkened, I had to prepare to have dinner at the villa and stop by the way, "My lord, what is the purpose of your barbed wire?" ”

"I tell you that these barbed wire fences are for use with muskets, and our troops place the barbed wire on the front line before using muskets to shoot, which is more effective and convenient than the fortifications of horses and antlers."

Lu Zhan remembered that during the First World War, barbed wire and trenches plunged both sides into the quagmire of war. The barbed wire fence halted the charge of the soldiers and horses.

It was a look of wonder to think of the enemy's infantry and cavalry when they charged at the musket phalanx and found the barbed wire in front of them.

"The lord is really a martial artist, and he can think of such a bad trick."

Lu Zhan almost didn't hit him after hearing what Duan Xiaohan said, is there such a boast of being smart.

"The subordinate just said wrong, the master's trick is not a loss but a cunning, and it is not called right."

"Forget it, I don't want you to praise me."

Lu Zhan, who had just eaten dinner, saw the first-generation barbed wire experiment sent by the blacksmith master.

Sure enough, the ancient craftsmanship is still not good, is it necessary to mix some other rare metals to meet the use standard. But where can metals such as manganese, potassium, and chromium be found, how to purify them, and how much to add.

Alas, it is really good to learn mathematics, physics and chemistry all over the world, but it is too difficult to be an art student by yourself.

"I'm afraid the forging process of these iron wires can't meet the demand, right?"

"Yes, what can I do, it seems that the craftsmen still need to try more." Lu Zhan put down the broken wire in his hand and fell into deep thought.

"I don't know if it's feasible." Duan Xiaohan patted his head and said.

As the saying goes, the wisdom of the people is endless, maybe Duan Xiaohan really has a way to solve the problem.

Seeing that Lu Zhan didn't speak, Duan Xiaohan continued: "My lord, you know about hemp rope, if we wrap the wire like hemp rope."

"You are really a little genius, why didn't I think you could be wound, the hemp rope is extremely resistant to wear after weaving, and the effect of the wire being wound like hemp rope must be similar." Lu Zhan patted Duan Xiaohan on the shoulder heavily, eager to hug Duan Xiaohan on the spot.

Without further ado, Lu Zhan and Duan Xiaohan wound the wire and made a simple version of the barbed wire with a wooden stake as a support point.

After experimenting with a few soldiers guarding the lodge, it was found that the wire mesh was indeed very useful, and if it took a lot of time to cut the wire with a knife, if it could have been set up two or three more, the soldiers with muskets would have more time to shoot.

These barbed wires were especially useful against cavalry, even the cavalry who led the charge could rush through the first barbed wire without fear of death, and there were several more behind. The obstacles formed by the dead horses and cavalry will also stop the cavalry from charging, and the cavalry who loses the speed advantage is equivalent to a death sentence.

"Lord, sure enough, the effect has been greatly improved after weaving the wire."

"yes, wait until the end of next spring to start the army. It's not too late now, and it's time to sleep. ”

"I'm tired after a busy day." Duan Xiaohan yawned and stretched, and then walked to the room he had temporarily arranged.

Just when Lu Zhan was wrapped in the quilt and just fell asleep, a courtyard in the courtyard of the Lu family's house in Yanzhou City was still lit.

"Sister, the people said that the young master took Commander Duan to the outside of the city this afternoon, and he slept outside the city tonight." As he spoke, Xiao Yezi picked up a coat and put it on Jing Nianshuang.
