People in Datang have been expelled from school

Chapter 275 The new method of making bows and arrows
I think Li Shimin will give it to himself, or because Li Ke is in charge of the guards in his village.

This is what Li Shimin is most at ease about.

Is Li Shimin really assured of himself?
This is not necessarily the case, Li Jiangshan's placement in Jingyang is Li Shimin's eyes.

He has never been at ease with me.

No matter how he develops, Li Shimin's paranoia of persecution will remind him to guard against everyone.

Li Ke picked up the bow and crossbow again, looked at the bowstring and said discouragedly: "How can this loose bowstring be used for training soldiers?"

"Of course this kind of bow can't shoot very far, and your loose power doesn't transfer much power to the arrow." Li Zheng looked at him and said, "This kind of bow can't even be used for hunting."

"You still know how to bow?" Li Ke said in surprise.

"I don't understand." Li Zheng shook his head vigorously.

Li Ke still looked at Li Zheng suspiciously.

Seeing Li Ke's frowning expression, Li Zheng said: "Okay, I'll recruit. I really don't understand bows, but I have seen a compound bow."

"Compound bow?"

"Your father said that we can give us weapons for five hundred soldiers, but he didn't say what kind of weapons, as long as we equip 500 soldiers, right?"

Li Ke nodded, "That's indeed the case. According to the emperor's intention, there can only be 500 soldiers in Jingyang with armored soldiers."

Li Zheng used a tree branch to draw the shape of a compound bow on the ground, and said, "Actually, a compound bow is about mechanics. The principle of a bow and arrow is the transfer of power, but this transfer is actually consuming. Power, the power shot out may only be three stones."

After Li Zheng finished drawing the outline of the compound bow, Li Ke asked curiously, "Are there wheels on it?"

"Yes, the advantage of the compound bow is that it reduces the consumption of power during transmission."

Li Ke blinked vigorously, "Sorry, I didn't understand."

Li Zheng came to the guard's warehouse alone, and took out a book from the system library, an academic treatise on the development of bows and arrows.

This book records in detail the history of the development of bows and arrows.

After the advent of muskets in the Middle Ages, the use of bows and arrows became less and less useful.

Slowly became the obsolete product in the war.

It became a pastime entertainment for noble families.

Bow and arrow has already become a kind of sports in later generations.

The bows and arrows of the Tang Dynasty already had the appearance that the recurve bows of later generations should have.

However, the accuracy and power of recurve bows are not as great as those of compound bows.

Bringing a bow from the camp, Li Zheng began to modify the longbow according to the size of the bow in his hand.

Shock absorbers, pulley shafts, separators, bolts.

It is too evil to be backward in knowledge, and Li Zheng castigated those guys with the five surnames again in his heart.

This group only knows how to be gentlemen but not how to engage in development scum.

Scholars all go to study rites and music, who will do development.

It is impossible to make a complete compound bow. In this age when even hardware technology has not developed, only a simplified compound bow can be made.

After drawing the parts, Li Zheng had a headache again. These parts needed iron to be made.

Then you need a blacksmith, Li Zheng called Dahu, because he is a general of the Longwu Army.

There are blacksmiths in the army who make weapons.

Knowing what Li Zheng was going to do, Du Hu said with some difficulty: "General Zhonglang, the ironware in the army is used to make weapons, so how can it be wasted."

"What I make is weapons, and I want to make the most powerful bow and arrow in Datang."

Du Hu looked at Li Zheng's drawing and said, "General Zhonglang, what kind of weapon is this?"

It's a bit difficult to explain these things to him, and I can't ask Duo to repeat that these are parts of a compound bow.

I'm afraid it wasn't a blacksmith who wouldn't even understand what a compound bow is.

Feeling the disadvantages of backward knowledge and technology in his heart, Li Zheng said to Du Hu: "I want to build these all privately. I, a Zhonglang general, want to build some weapons for my own use. There are so many weird weapons in this world." Now, do you know a weapon with an iron head on a rope?"

Duhu shook his head, "I don't know."

"That's it, make five hundred copies and send them to me."

"General Zhonglang, it's not right to do this. It's okay to make one or two pieces. If it's [-] pieces, it must be approved by the Ministry of War, because the Ministry of War must provide the iron materials."

"Then I will go out of the head office myself."

"Okay." Duhu said again: "But I need a little bonus fee, which is charged by the blacksmith, according to the rules."

Li Ke also explained: "It is indeed the case. The powerful people in the market really want to give some benefits to blacksmiths to make things. Not much, just a few pennies."

Li Zheng took out three silver cakes, "These three silver cakes should be enough for a hundred coins."

Duo pulled the bullock cart and took away all the five hundred armors in the camp for the iron materials used to make parts, and just recast them.

Li Zheng was sure that even if they made the parts, the blacksmith would not know what they were building without a complete drawing.

"Where's Cheng Chumo?" Li Zheng looked around and asked.

"Back to Chang'an." Li Ke said while eating a piece of cake.

It is definitely not enough to use the current beef tendon for the bowstring of the compound bow.

The strings required for compound bows require high strength.

I found some bamboo slices and soaked the bamboo slices in the water.

Wait until the fibers of the bamboo slices are separated and become thin lines.

The fiber toughness of bamboo is very good.

Wrapped over tendon for added strength.

In the palace, Li Shimin was reviewing the memorial, and Wang Ding came with a blueprint, "Your Majesty, Li Zheng asked Long Wujun to build things."

"Is it a horseshoe again?" Li Shimin said without raising his head.

Wang Ding put the drawing in front of Li Shimin, "The blacksmiths of the Longwu Army couldn't understand what it was, they said it looked like a toy."

Li Shimin glanced at the blueprint, frowning but couldn't see anything.

Wang Ding said again: "It is said that Li Zheng recast all the armors of the five hundred soldiers sent by His Majesty. To build this thing, the people of Longwu Army came to report immediately, and please Your Majesty to make a decision."

"It's not just a few little things."

Wang Ding said again: "According to what Li Zheng said, five hundred pieces each should be built."

"Is he going to waste the armor I gave him like this?" Li Shimin sneered and said, "Just do what Li Zheng said, and let him go."

"Here."

After Wang Ding resigned, Li Shimin had no intention of reviewing memorials.

Li Zheng had to recast all the five hundred deputy soldiers.

I don't know that this kid doesn't like the armor he gave him.

Or is it that he doesn't want to properly organize his parts at all.

I went to see it a few days ago, although those people were just some villagers.

But the training is very good.

It would be a pity if Li Zheng didn't pay attention to it.

For three consecutive days, Li Zheng has been making bowstrings for compound bows.

In this era without high-strength polyethylene materials.

Just make do with it.

Mix bamboo fiber with hemp rope and beef tendon to make chopsticks thick and thin.

Then waxing, the benefits of waxing can increase flexibility and increase service life.
