readx; The monkey saw Yun Zheng stop next to a strange big iron pipe, holding the iron pipe up and down, left and right, looking very excited, just like a bride saw her husband who had returned from afar, and her eyes almost burst into tears. Pen % fun % Pavilion www.biquge.info

Taking advantage of this opportunity, he hurriedly lifted the handsome feet and put on the pair of lazy shoes, even if the socks were forgotten, there were many people, and it was not good to be stared at by everyone to watch the handsome change socks.

Yun Zheng put his hand into the barrel of the cannon and stroked it, but found that it was very flat inside, not as rough as he imagined.

The round shape of the barrel is also very good, there is not a single trachoma on the body of the cannon that is more than one zhang long, and the barrel is patted with his hand, making a snapping sound, and the wall of the pipe is more than an inch thick is very thick, and at a glance you know that this thing is very strong.

"Have you tried it?" Yun Zheng glanced back at Sun Jie, who had come to deliver the cannon.

Sun Jie is a person from Camp A, the first batch of old people to go to the Eagle's Nest, in the past, he has been responsible for the placement of the dependents of Camp A, and he easily did not leave the Eagle's Nest.

"Not yet."

Yun Zheng frowned and said, "Why don't you test it, I remember that the matching projectile has been developed a long time ago." ”

Sun Jie snorted for a long time before he said: "Second Duke ......"

Yun Zheng suddenly realized: "You mean Yun Yue didn't let you experiment?" ”

Sun Jie said embarrassedly: "This kind of thing has been cast in our ironworks for a total of five, after the second prince went to the Eagle's Nest, he brought these five cannons to the mountain, and when he came back, he asked the small one to send this cannon to the general." He went to Dengzhou with two other cannons. ”

Yun Zheng looked up and looked around, and found that all the old men from Camp A were gathered around him, and he didn't have any worries about leaking secrets, so he smiled and said, "Since Yun Yue doesn't let you test, it's also for your good." lest the military aircraft be leaked in the Eagle's Nest, where there are many people.

Sun Jie, tell me, is this thing troublesome to cast? Did it mint as I asked it to? Is there a problem in the middle? ”

Sun Jie laughed miserably and said: "Back to the general's words, for these five cannons, the ironworks injured four people, because it was the whole clay casting. More than 1,000 catties of molten iron should be injected into the mud fan at one time, and it is common for the molten iron to explode with a slight deviation.

Since receiving the general's military order, the ironworks have not done anything else for more than a year, and only sixty clay models have been made by casting these things, and only fourteen have succeeded in the end. After screening, the waste with trachoma bubbles was removed, and only these five could barely be seen.

The casting master from the Beijing division and the master craftsmen of our iron-smelting factory have been sleepless, and they can only make these five cannon barrels......"

After listening to Sun Jie's complaints, Yun Zheng said with a smile: "It's very good, it's nothing to waste some money, as long as you can make these things, it will be a great achievement, and I will naturally reward you for your merits." It's just that you need to make more of this stuff in the future. ”

Sun Jie looked around and whispered in Yun Zheng's ear: "It can't be done, the second prince has moved the iron-smelting factory to Dengzhou." The master craftsman of the Eagle's Nest, a casting master from Tokyo, took all of them away, saying that he was going to rebuild the workshop on Wild Ass Island. ”

Yun Zheng shook his head and smiled, he didn't care, the current Yun Yue was different from the previous Yun Yue, he now paid more attention to the construction of the sea. The Yun family will settle down on the sea in the future, and there is no sharper weapon than artillery in naval combat.

Think about it. When other pirates are still in the stage of chasing me and daring, and then jumping ship with a knife in their mouths. The Yun family's fleet was already able to start attacking people from a distance of one or two miles, and with the weapon of artillery, the Yun family could not have any opponents at sea.

China is the hometown of artillery, Yun Zheng knows this very well, it was the emergence of gunpowder that gave birth to this thing, and there were many gunpowder weapons in the Great Song Dynasty, but in Yun Zheng's eyes, they were all messy things, and there were more scaring ingredients than practical use.

Assault spear Yun Zheng has seen that this thing is used as a hidden weapon by many soldiers, just like a large firework, and the sparks that spew out do not have much purpose at all, because the casting process cannot keep up, and the number of times they injure themselves is far more than the number of times they burn the enemy.

In the Great Song Army, many people have some secret weapons handed down by their families, and the assault rifle is one of them, the guy who uses this kind of thing only takes it out when the war is at its most tense, but when the baby takes it out, it disrupts the structure of the military formation, not to mention that this thing sometimes explodes in the hand, not only can not hurt the enemy, but sometimes it will affect his own brothers, so the soldiers in the Yun Zheng army are strictly forbidden to arm themselves.

Many times Yun Zheng couldn't figure it out, obviously the most rudimentary front-loading smoothbore cannon like the assault rifle had already appeared, why no one had made great efforts to study this thing, so that later people still had to use the so-called Hongyi cannon.

Later, he also asked people to set up a few cannons on the coast, and the country was easily blasted open.

Yun Zheng thought that this kind of thing of flowering inside and outside the wall should be strictly prohibited.

Modern artillery was developed from the stone thrower, which was invented in ancient China.

A stone thrower is also called a stone truck. Its structure is very simple, make a horizontal axis on a wooden frame, and intersperse a long rod between the axis and the horizontal axis, one end of the rod is tied with a leather hole containing stones, and the other end is tied with dozens or more ropes. When using, put the stone into the leather hole, and when an order is given, everyone pulls the rope together, and the leather stone is thrown out as if it were flying.

The first use of the stone thrower in warfare was in the Spring and Autumn Period and the Warring States Period. According to the National Chronicles. The Book of Wei records that during the Battle of Guandu, Cao Cao used a stone thrower to break through Yuan Shao's stronghold, thus winning a complete victory.

During the period from the Han to the Tang Dynasty, although the use of stone throwers in combat gradually increased, the scale was generally small. During the Tang Dynasty, the stone throwing machine became bigger and bigger, and some needed one or two people to pull the rope to throw the boulder, and each stone could kill several people.

In the middle of the Tang Dynasty, the invention of gunpowder made a qualitative leap in the development of stone throwers.

It was not until the beginning of the Great Song Dynasty that gunpowder was used on a large scale in the military field.

The stone thrower then changes from throwing stones to throwing fireballs. Fireballs are also known as gunpowder bullets. The main purpose is not to blow people up, but to burn people, and the efficiency is outrageous.

It wasn't until Yun Zheng improved the gunpowder formula that the way gunpowder hurt people changed from burning to exploding, and the efficiency of killing people skyrocketed tenfold.

Of course, the rear-loading cannon is advanced, and the efficiency of the bombardment is also high, but Yun Zheng has no ability to make that kind of cannon now, so he can only take out the oldest Hongyi cannon to fill the number, and now he can only fire solid bullets, iron sand, or chain bullets, and it is nonsense to use this kind of cannon to deal with the cavalry, under the confrontation between the two armies, the cavalry will be killed in front of him in a few breaths, and this kind of cannon can only fire a shell in about two minutes, if you expect this thing to deal with the Liao or Xixia cavalry, it is purely looking for death.

After a shell flies out, the artilleryman must quickly fill the barrel with water, then clean the chamber with something like a mop, then fill the gunpowder, stuff the fire rope in the gun hole, pound it firmly, stuff the solid projectile into it, and finally light the powder rope again, and slowly wait for the powder to finish...... By the time all this was done, the cavalryman's blades had already been cut to the head.

The reason why Yun Zheng wants to build such a thing is simply to attack the city, as long as he pushes this thing to the edge of the city gate and aims at it, more than a dozen catties of projectiles hit the city gate with overwhelming force, and no matter how strong the city gate is, it can't withstand a few such shells.

Chen Lin also put on his clothes and came out, in the face of this heavy and unspeakable thing, I really can't think of any use for this thing, this time after Yun Zheng's army went out of Yanmen Pass in Dai County, what he wanted was to quickly cut off the connection between the east and west of Liao, take Xijing of Liao with lightning speed, and then march eastward, and finally intercept the reinforcements from Zhongjing Road in Liaoguo in the area of Gubeikou, if he brought such a heavy iron bump, how could he maintain a fast march?

Yun Zheng's white teeth were particularly eye-catching in the night, and without waiting for Chen Lin to ask, he said to Chen Lin with a smile: "Don't look at this thing as bulky, but this thing is a sharp weapon for attacking the city, even if it will be slower because of it, but we have to break through at least seven fortified cities on this one, with this thing, it is not a problem to attack the city." ”

Chen Lin also looked up and down at the thing in front of him, he really couldn't figure out how to use this thing, seeing that Yun Zheng didn't seem to introduce himself to the use of this thing, he frowned and said: "The military plane is fleeting, if you slow down the trip with this thing, the old man won't help you explain it to the center and Your Majesty." ”

Yun Zheng saw someone who dared to despise him for the first time, and said to Chen Lin with a smile: "After you have seen the power of this thing, I guarantee that you want to hug him when you sleep." ”

Chen Lin said with a smile: "If this is the case, the old man will wait and see, this battle is a confrontation between a dignified and upright division, and the old man does not want you to lose the battle of the army because of these small tricks!" ”

Yun Zheng laughed and said: "Old Chen Lin, you are just a supervising army, you have never been on the battlefield in your life, and now you have a military aircraft on the left and a military strategy on the right, are you sure you understand what you are talking about now?" As long as I don't run away on the battlefield, you can stand aside and watch me attack the city and bring such nonsense! ”

Yun Zheng's words were very rude, but Chen Lin was not angry, the old guy didn't care about Yun Zheng always wanting to provoke him, in his opinion, as long as Yun Zheng honestly went to the battlefield and helped the Great Song Dynasty win the battle of the year, he didn't care about the rest, for a person who even wanted his life for the Great Song Dynasty, except for victory, the rest were stubble.
