Chu Zhen doesn't know swords, he doesn't know armor, T10 high-carbon steel or something, and they are all boasted by the boss who sells cold weapons.

He picked up a spear in the pile of weapons and said with a smile: "No matter how good the sword is, it is an accessory, you mostly use guns in war, right?" ”

Don't look at how many modern people boast about swords, sword saints, sword heroes, sword gods, etc., but as far as Chu Zhen knows, guns are the mainstream weapons on the battlefield.

"Use a bow and a gun."

Li Shimin also picked up a spear head, and explained while looking at it: "The two armies must be in formation when fighting, and they need to advance and retreat with a basis to be able to keep the formation from disorder, before the battle, the bow and arrow can be thrown from 30 zhang away, and when the battle is engaged, the spear resists the enemy, and the shield is defended, and when it comes to chaotic battles, it is to draw out a big knife and slash, or charge the battle with a spear, and swing it widely, so that the enemy is cowardly." ”

Chu Zhen nodded, "This is the role of a fierce general, not necessarily killing many people, but leading soldiers to charge into battle." ”

Li Shimin mentioned charging the formation many times, which can see the importance of maintaining the formation in ancient wars.

"It's a good gun, too!"

Touching the head of the spear with his sword, Li Shimin praised: "Find a good white wood and put it on it and make it into a horse lance, which is a magic weapon that can make soldiers love it!" ”

"What's the difference between a horse, a gun, and a spear?"

Hearing him say that he would make the head of the gun into a horse lance, Chu Zhen asked.

"In the Han Dynasty, it was often called a spear, but now it is often called a gun."

Li Shimin said: "Charging on horseback pays more attention to the length of the gun, so the spear used by the cavalry is longer than the gun of the soldiers in the array. ”

Chu Zhen thought of Cheng Biting Jin, in the Sui and Tang Dynasty novels, the demon king of the mixed world used an axe, commonly known as a three-plate axe.

But in fact, in history, Cheng Biting Jin made good use of the horse lance.

"In the Ming Dynasty, no one called the gun a horse lance anymore."

Zhu Yuanzhang put down the poems of Li Qingzhao and Lin Daiyu, also stood up, and came over to look at the pile of weapons.

The first thing he picked up was a piece of armor in the shape of scales.

"It's all steel with holes in the middle? It's all the same......"

Zhu Yuanzhang said to himself, picked up the cloak again, looked through how the pieces of scales and armor were strung together, and bent the cloak again to see if he could flexibly swing and slash after wearing it.

After looking at the cape, he picked up his helmet again, took off his hat, and tried to put it on.

Li Shimin also picked up the leg skirt and looked at it, and after asking Chu Zhen's permission, he slashed it with his sword.

"Ding."

A string of sparks emerged, and a hole appeared in the steel sheet on the leg skirt, but the whole thing was intact.

Li Shimin looked at the sword in his hand again, revealing a look of surprise.

The sword and armor were sharp and strong beyond his imagination.

Chu Zhen said with a smile: "It is a felony to secretly possess armor in ancient times, but in our place, you can buy it casually." Moreover, it is stainless steel, so it is not easy to rust when soaked in water. ”

"Stainless steel?!"

Li Shimin was shocked by this non-rusty piece of iron.

"How much does this set cost?"

Zhu Yuanzhang touched the pieces of silver-white scale armor, his expression was calm, and he seemed to feel that it was like this.

"Five thousand, including armor and a sword."

Chu Zhen reported a number and explained: "Your penny is about equal to our two yuan, but the actual situation is more complicated, for example, silver is not very valuable, but a gold ingot of twenty taels can be sold for two hundred thousand yuan." ”

"A penny is two dollars...... Twenty taels of gold ingots is 200,000 yuan, can you buy forty sets of such armor?! ”

Zhu Yuanzhang's calm expression finally changed.

"Almost."

"You can buy as much as you want? How much do you want? ”

"Buy whatever you want."

"I want 100,000 sets!!"

As soon as Zhu Yuanzhang opened his mouth, he was 100,000 armor, his expression couldn't be suppressed, and he was completely excited!

The 100,000 soldiers of the Ming Dynasty wore such armor, and the powerful force formed by the array alone was enough to frighten the courage of the Northeast Yuan and the Northern Mongolian tribes.

This is a well-made, first-class armor, which only generals can wear in the Ming Dynasty.

Not to mention that these pieces of iron are actually rust-proof!

Several people looked over one after another, and Li Qingzhao, who was sitting in Chu Zhen's position, also put down Hu Weiyong's strategy, walked over and watched beside Chu Zhen, and forcefully picked up a fish scale armor from another box.

"I want 10,000 sets too!"

Without waiting for Chu Zhen to speak, Li Shimin also came over to buy arms, "I also have gold, I just seized many treasures from Xue Ju, and there are thousands of gold ingots in the warehouse." ”

Looking at the two of them, Chu Zhen laughed: "Although you can buy it casually, how do you bring it back?" ”

Zhu Yuanzhang's excited expression suddenly froze and looked at the stairs.

"Besides, buying too much can also attract people's attention."

Chu Zhen didn't explain.

The impact of exposing the Chronicles of Time and Space was too great, and he didn't want to risk the unknown.

"It's a pity ......"

Zhu Yuanzhang sighed and said, the scene of 100,000 Ming troops wearing armor and arraying and scaring Beiyuan is gone.

Li Shimin was also disappointed.

"Don't worry, there's an artifact!"

Chu Zhen picked up a bow, handed it to Li Shimin, and said with a smile: "I heard that Erlang, you are good at riding and shooting, come, let's see how this bow is!" ”

“……”

“……”

Words can't describe Li Shimin's expression at this moment, he is holding this bow, no, he is holding this thing, looking at it, and then at Chu Zhen, a picture of "Are you sure this is called a bow and arrow?" Expression.

"This is a bow?!"

Zhu Yuanzhang was also shocked, and he said for a long time: "It looks like a bow, but what are these two wheels?" ”

For the first time, he had seen someone tie the wheels used to hang things to the ends of bows and arrows.

Isn't this a joke?

"Haha, don't doubt it, it's a bow!"

Chu Zhen laughed, picked up another bow and handed it to Li Qingzhao, and said, "You all take a look and try our archery feel here." ”

With that, he walked back to the computer desk and showed Hu Weiyong's strategy to Lin Daiyu.

This time, he didn't explain a word, he looked at Sister Lin, smiled at her, put down his strategy, continued to walk back to Li Shimin, took the bow and arrow in his hand, and began to explain to them.

"It's called a compound bow, don't look weird, in fact, it's all technology and ruthlessness!"

"Technology... With ruthless work? ”

The three of them were confused.

Chu Zhen explained: "For example, these wheels, don't look weird, but with it, the force of pulling the bow can be reduced by half, you are good at using bows and arrows, you should know what it means to be able to use only half the force to achieve the effect of pulling the bow with all your strength." ”

He took an arrow casually, put it on the bow, pulled the bowstring, aimed it out of the window, and didn't need to aim, just let go of the bowstring directly at the wasteland, and let the arrow fly out through the window, "That's it, I'll simply pull the string, but I can achieve the effect of pulling the bow with all your strength!" ”

Seeing this, Li Shimin was deeply moved.

Not for effortlessness, but for precision.

Pulling the bow with all your strength requires you to tense your arms, and when shooting an arrow on horseback, it takes time to aim, so you can't hold the bow for too long.

Replacing it with the compound bow that Mr. Chu said, with half the force, the arrow can penetrate the enemy's armor, and the time it can aim is greatly increased.

Even if he holds a compound bow and pulls the string with all his might, wouldn't he be able to shoot arrows a hundred feet away?!

If you shoot an arrow at someone within ten zhang, I am afraid that you will not be able to shoot the opponent's general off the horse.

The power of this compound bow may be ......

"I don't understand."

Zhu Yuanzhang held a compound bow and looked at its wheels with a frown: "How can you save effort by adding wheels?" ”

"The fixed pulley can't save effort, but the movable pulley and pulley block can."

Chu Zhen explained slightly, "Look carefully, this is a big pulley with a small pulley, and the big wheel is irregular and round......

Strictly speaking, it does not save effort, but saves the power when maintaining the state of drawing the bow, so that the power is accumulated, and then released after releasing the bowstring, and the large and small wheels can increase the speed of the bowstring rebounding, so that the arrow shoots faster! ”

After explaining, he looked at the two of them.

Li Shimin seems to understand whether he understands or not, and Zhu Yuanzhang half-understands and half-understands.

Chu Zhen looked at Li Dacai, Li Qingzhao smiled at him and said, "It turns out that Chu Langjun has learned this. ”

She has never regarded Chu Zhen as a person who does not learn and has no skills, although his writing style is very poor, and his writing is miserable, and it seems that the articles she writes are also very laborious, and even he calls himself a layman.

But Li Qingzhao has always known that Chu Langjun is actually a talented and knowledgeable person, which can be seen from his confident temperament, good conversation, and the room full of books.

Previously, Chu Langjun fiddled with the computer, she just looked at it, but now that he explained why the compound bow was so strong, she had a slight peek at Chu Zhen's talent.

Sure enough, as she guessed, Chu Langjun was erudite and talented, far beyond what she could compare.
