Chapter 239 Take Jiao Yu back to the base

300 steps fixed target, 200 steps mobile target, this is Zhang Yang has always required for the army. In fact, the latter requirement is more practical, because the enemy is not a wooden man and will not stay there waiting for you to fight. The Tianque in his hand is not a fire stick. Anyone who can't meet the requirements has to become a spear soldier. This excitement is huge. Every soldier practices diligently.

The backyard of the government office is very empty. Zhang Yang stood there and said to Jiao Yu, "Do you see the back door? There should be 300 steps from here to the back door, right?

Jiao Yu nodded. There were indeed 300 steps, but it was a very good result to shoot at the back door at this distance.

"Take the sky and bring it!" Zhang Yang said to the guards around him.

The guard handed Tianque to Zhang Yang. Zhang Yang skillfully pulled the lever, completed the loading of the bullet, moved the ruler to the position of 300 steps, aimed, and pulled the trigger without hesitation.

"Ban!" The needle hit the flint, and the spark ignited the gunpowder. The gunpowder gas pushed the lead bullet, turned out in the gun barrel and flew forward.

Only hearing this sound, Jiao Yu was speechless. There was no fire rope and no gunpowder. How was this projectile fired? Jiao Yu's technology is also limited to the level of the fire rope gun. The fire gun he developed for Zhu Yuanzhang had to be ignited with an open fire before it could be launched.

Zhang Yang did not finish the clinker. Then, he quickly pulled the upper lever, completed the loading, and pulled the trigger again without hesitation. This time, he aimed at the bird that had just been shocked on the branch due to the launch of the fire.

"Ban!" With the second sound, a bird in the sky fell down.

If the first fire made Jiao Yu feel only shocked, this second sound completely made Jiao Yu despair. What kind of fire is this? After the first launch, can the second launch be carried out so quickly? Moreover, the head was still so high that he didn't see where the back door was hit at all, but the little bird in the sky had made Jiao Yu's heart like ashes.

His skills are not as good as others. If he hadn't come to Gaoyou Mansion and killed him, he wouldn't have believed that there would be such a powerful weapon in the sky!

Of course, Jiao Yu knows what these two continuous fire sounds mean. Quick loading has always been the problem he wants to solve. However, he has always been unable to load those gunpowder, load bullets, and ignite the fire ropes. These simple steps are completed in one step. Just by touching the pull rod above, it will be completed. Is it? It's simply a replica of Zhuge Lianyu!

Shot the bird in the sky, which made Jiao Yu sigh that he could do it. However, he used a shotgun, full of iron sand. After shooting down the bird, his whole body was covered with iron sand, and it was useless. And this bird was a particle bullet, only a bullet, how high the head should be! Birds fly in the sky, which is more difficult to hit than the cavalry on the ground!

"It's a pity that there are no wild ducks here. Otherwise, beat a few ducks and let Brother Jiao Yu taste the game." Zhang Yang said with a smile, but found Jiao Yu. He suddenly took off his clothes and knelt down.

"Big brother, please take my younger brother as an apprentice. I thought I knew the most about firearms, but who knew it was sitting in the well and watching the sky. Today, when I saw the eldest brother's firearm, I knew that there was someone outside. There was a mountain outside the mountain. My younger brother had no other hobbies. Please accept Jiao Yu. Jiao Yu is willing to follow the eldest brother's side to learn the eldest brother's firearms-making technology.

Jiao Yu's move shocked everyone present. Shi Nai'an shook his head at Zhang Yang vigorously. This apprentice is not easy to collect. As the saying goes, the apprentice will starve the master to death. Moreover, who knows, this apprentice will bite back. After all, he came from Zhu Yuanzhang's side. Who knows if it's an undercover agent?

"Brother Jiao Yu, please get up." Zhang Yang said.

"If the master doesn't agree, then I won't get up." Jiao Yu is very stubborn.

Zhang Yang smiled, and he guessed that after seeing the power of Tianque, Jiao Yu must have a very strong reaction, but this reaction was still beyond his expectations.

Zhang Yang thought for a moment, "You can ask me to promise to be your master, but there is a prerequisite."

"Say one, a hundred is also okay."

"You have to go to a place where you can contribute the gun casting technology you have mastered and make the most advanced artillery you have mastered. After that, I will decide whether to teach you this fire gun technology, but once you go to that place, it is likely that you will not be able to get out for the rest of your life." In fact, this is also the third condition that Zhang Yang just wanted to say. After all, Jiao Yu is a person who can enter Zhu Yuanzhang's eyes, proving that his firearms are indeed extraordinary. Such a person can use it for himself. Of course, he has to dig it without hesitation.

" OK, I promise you." Jiao Yu said.

"Don't you regret it? That place is isolated from the world and can't come out of the whole life. Can you accept it?

"If you can worship the eldest brother as your teacher, even if it is a sea of swords and fire, Jiao Yu is willing to go. If Jiao Yu can't learn this fire skill, I'm afraid she won't live a down-to-earth life." Jiao Yu said.

"Ally, then follow me, guard, prepare the ship!" Zhang Yang said.

Shi Nai'an pulled Zhang Yang in the back and whispered, "Master, are you really going to take him to the base?"

"Yes." Zhang Yang said.

"The base is our secret. Is it risky to let an outsider enter like this?" Shi Nai'an said that his worry was reasonable. Jiao Yu was Zhu Yuanzhang's person.

"Don't worry, I have confidence." Zhang Yang said.

Zhang Yang is more clear about people like Jiao Yu. To put it bluntly, he is a firearm fan and obsessed with infatuation. Zhang Yang believes that Jiao Yu worships himself as a teacher, which is an expression of true feelings. Besides, as long as Jiao Yu is put on the base, he is not going to let him out. The maze of winning the lake is not something that a nerd like Jiao Yu can turn out.

And the one I need most is artillery manufacturing. Zhang Yang developed the fire gun to the extreme, which was based on his understanding of this weapon. In contrast, Zhang Yang knew less about artillery. All he knew was that in this era, bronze cast artillery was used, and the barrel was very thick and very short. It was over to fill the gunpowder, loaded the projectile, and flew the projectile out. It's done. Similarly, the accuracy of the projectile is very low. Unless the enemy is killed with a shot, it will not have much power at all except for the amazing momentum. It is completely different from the modern cannon with long barrel.

In the future, when attacking large cities and water battles, Zhang Yang will need artillery. Although the principle of fire and artillery is the same, the thin pipe is called fire and the thick is called artillery, but it is still very different when it is really made. The gun has a large amount of charge and a large load. In order not to blow up the barrel, the amount of charge and the thickness of the gun barrel are very exquisite, and these things need experience and repeated experiments, and this task can be completely handed over to Jiao Yu. He is sure that Jiao Yu is very willing to do this work.

Zhang Yang took Jiao Yu and followed a hundred-man escort to take a boat from the west of Gaoyou to Desheng Lake.

Originally, the most appropriate thing was to ride a horse to the murder port and then take a boat to the base, which would save time. However, in order to keep it confidential, Zhang Yang let Jiao Yu stay in the cabin as soon as he got on the boat. In this way, Jiao Yu didn't know where the ship was going at all, which could prevent accidents.

Of course, on the surface, Zhang Yang can't make Jiao Yu feel that he is restricting him, because Zhang Yang has also been staying in the cabin and pulling Jiao Yu's parents.

Jiao Yu was born in a firearm family. He was an alchemist and discovered gunpowder for a long time, and began to apply his research to the military field, such as making articles on catapults, throwing incendiary bombs, poison bombs and explosive bombs, and began to try to make devices that rely on gunpowder to launch projectiles. In the family, there have always been many talents, which have been passed down to Jiao Yu's generation. After Jiao Yu's careful research, with his intuition about firearms and various mechanical knowledge, he improved the fire to the stage that he could be fully put into actual combat. Moreover, he tried to cast a cannon and finally succeeded.

After walking for a day, after a curved maze, I finally arrived at the base. It was already dark at this moment.

"Jiao Yu, we are about to go ashore. You should also know that the place where you come now is the core secret of Zhang Shicheng. Therefore, once you go up, you will never be able to get out again. I hope you are prepared for this." Zhang Yang said.

"Don't worry, master, Jiao Yu is willing to stay in this place for a lifetime, as long as I can learn the master's craftsmanship." Jiao Yu said.

"If you want to learn the principle of Tianque, you can build the cannon for me first, and I will teach you everything I have learned. Moreover, I will open a school so that more people can master this skill." Zhang Yang said.

School? Jiao Yu didn't take it to heart. He probably thought that the master was ringing the bell for himself. It was not until later that Jiao Yu served as the dean of the Central Academy of Weapons. Looking back again, he found that the master was so wise and prepared for a rainy day.

Back to the base, Zhang Yang has another purpose, which is to see how much the steam engine has been built. Although those people began to make it after their explanation, no one has seen a physical object. How much it can be made depends on their comprehension ability. Zhang Yang intervenes in time to guide it, or It can play a role.

Steam engine, cannon, after these two things are done, they can be modified to warships. In the south, water warfare is inevitable, especially Chen Youliang, who has not yet appeared. In the battle of Poyang Lake, Zhu Yuanzhang was almost buried with water.

The ship quickly docked, and the smiling Lu Xing and Li Bosheng were already waiting on the shore.

"Brother, I'm looking forward to you," Li Bosheng said. Is this one?" Looking at the white-faced scholar-like figure behind Zhang Yang, there was still a piece of blue and purple on his face, and Li Bosheng was puzzled.

"This is Jiao Yu. I'll bring him to the base and cast a few cannons." Zhang Yang said, "In the future, you will work together. by the way, first transfer ten hands to Jiao Yu. Casting cannons is also individual work, and you can't do it alone."

Jiao Yu? Casting cannon? Li Bosheng arched his hand and said, "Brother, welcome to the base. We will be brothers in the future. If you need anything, just ask, and we will help as much as possible."

Zhang Yang then introduced to Jiao Yu: "This is Brother Bo Sheng. He is mainly responsible for the manufacture of Tianque."

Knowing that the person in front of him was the supervisor who made Tianque, Jiao Yu immediately replied, "In the future, there will be brother Lao Bosheng. Please give me more advice!"

"I can't talk about it, I can't talk about it." Li Bosheng said with a smile.

"This is Brother Lu Xing. He is mainly responsible for ironmaking. The fine iron you need to cast artillery is completely provided by Lu Xing. You two should coordinate and cooperate with each other to build the artillery as soon as possible." Zhang Yang said.

Refined iron? Jiao Yu was not in a hurry to return the gift this time, but said to Zhang Yang, "Master, we have to use bronze to cast cannons!"

Master? When did this boy worship his eldest brother as his teacher? Li Bosheng and Lu Xing were a little surprised.

Zhang Yang said, "The cost of the bronze casting gun is too high, and the copper is soft. After using it for a long time, the muzzle will be deformed. Using fine iron is the king's way."

Bronze cannon? If I want hundreds of copper cannons, how much will it cost? Zhang Yang thought to himself that he couldn't afford this thing.

"But if you use iron, you have to use good fine iron. The iron is crisp and easy to fry." Jiao Yu said.

"You don't have to worry about the quality of iron. With Lu Xing, there are many fine irons." Zhang Yang said, "You are tired these days. Let Lu Xing take you to rest first!"

I'm not tired yet! Before Jiao Yu's words were said, she was pulled away by the enthusiastic Lu Xing.

"Brother, is this Jiao Yu really your apprentice?" Seeing that the two had gone far away, Li Bosheng asked.

"Not yet." Zhang Yang said, "When his artillery is successfully cast, even if it is officially my apprentice, I promise him that after he casts the cannon, I will teach him the principle of Tianque. But before that, it must be kept secret.

"Yes, big brother." Li Bosheng said.

"Draw a field for him and let him specialize in artillery research. At the same time, don't let him come into contact with the manufacture of our Tianque, especially the manufacture of the barrel." Zhang Yang said.

"Is this person unreliable?" Li Bosheng asked.

"I hope I'm not wrong," Zhang Yang said. "He was originally a person of Zhu Yuanzhang. He shouldn't have been brought here, but he is really a genius in firearms. If he really relies on us, he can consider handing over the manufacturing of Tianque to him in the future, and you can lead the army to fight. It's done."

"Thank you, big brother!" Li Bosheng replied happily.

Although Li Bosheng didn't say anything, Zhang Yang also knew that he saw that other brothers who grew up together were fighting and making contributions, and he had been encircled in the base and could not get combat achievements. He must have some grievances in his heart. The previous few times, he was also meant to give him credit. It was hard to stay in the base for so long. It's him.

"Li Youcai and Zhao Jiamin, how is their research going?" Zhang Yang asked.

"Brother, what kind of steam engine do you mean?" Li Bosheng said, "Since they listened to the eldest brother's explanation, they have been working hard these days. The parts have been prepared and said that they were about to be assembled."

"Okay, go and see them tomorrow!" Zhang Yang is very happy. He has been staying at the base for the past few days. He can watch the manufacture of the steam engine and the Jiaoyu casting cannon. Recently, the army in Yangzhou has been transferred, and Gaoyou Prefecture is safe for the time being.

The night gradually deepened, and the whole base fell into a vast silence. Only the tired workers snored when they slept, fused with the sound of the wind outside, calm and peaceful.

Jiao Yu couldn't sleep at all. When he saw the huge power of Tianque for the first time, he was overjoyed. The advantages of this kind of firearm are very great. The filling is simple, fast, and the hit rate is high. If he hadn't seen it in person, he would not believe in the power of this kind of fire. He was very eager to know the principle of this kind of fire and how to launch it. Question mark There is no need to light a fire! How to fill it? I didn't see anything stuffed in from the mouth. What are those two levers for?

In addition to joy, I'm just worried. Casting cannons with fine iron has very high requirements for fine iron. Hundreds of steelmaking are almost the same. However, with hundreds of steelmaking to cast cannons, the consumption of this kind of molten steel is also sky-high. Can there be so much steel on this island? When he came over, he seemed to see several tall devices. I don't know what they were. Tomorrow, I will make a mold for casting cannons first, and by the way, let's see if there is any refined iron that meets the requirements.

Jiao Yu never thought that the master asked him to cast a cannon for actual combat. He just thought that he was being tested, so he must cast the cannon well in order to gain a higher position in the master's heart.

He likes this feeling, which is much better than in Zhu Yuanzhang's barracks. He didn't come in vain. Although he suffered a few times, it was worth it. He just saw them falling asleep and was embarrassed to wake them up. Take away the research first. They were indiscriminate, and they came up with punching and kicking. What a savage!

Zhang Yang didn't fall asleep. He was carefully thinking about modern cannons, cannons, howitzers, tank cannons, mortars, and so many kinds of cannons, but he was not very familiar with any principle, and there were more shells, armor-piercing bullets, grenades... so many things, repeatedly recalled in Zhang Yang's mind, putting aside the complex The superficial phenomenon and the pursuit of its most essential things are the key to solving the problem!

Why is Tianque is advanced? Because of the emption, the gun he wants to cast also has amazing power, and the emption is also necessary. He can almost imagine that even if Jiao Yu casts his best gun, it can't meet his own needs. Let Jiao Yu make the cannon is just a test of his true ability.

After confirming that Jiao Yu is really a firearms genius, he was asked to test two kinds of artillery. One is a relatively long barrel and a thin caliber. It is engraved with rifling, which is used to launch iron shells wrapped in a layer of lead on the surface. The shells cannot be round. It must be the kind of sharp shell of modern times, which reduces air resistance and increases the range. This kind of fire Cannons are mainly equipped on warships and used to attack strong cities. The surface is covered with lead so that it can be squeezed by the suff and rotated. If it is all iron, it will be flattened in a few times. If it is all lead, the cost is too high. After all, lead is a rare metal, and lead is too heavy.

The other one is similar to a mortar. It has a short body and a thick caliber. There is no rifling and a shotgun inside. This kind of artillery is mainly used to kill the other side and equip the field troops.

However, these are all assumptions. After Jiao Yu's experiment is successful, leave these tasks to him!
