Chapter 239: Bring Jiao Yu back to the base

Three hundred steps to fixed targets and two hundred steps to move targets. This is what Zhang Yang has always asked 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 hit. The Tianque gun in his hand is not a fire stick. Anyone who cannot meet the requirements must be turned into a spear soldier. This stimulation is huge, and every soldier practices diligently.

The backyard of the government office was very empty. Zhang Yang stood there and said to Jiao Yu: "Did you see the back door? From here to the back door, there should be three hundred steps?"

Jiao Yu nodded. There were indeed three hundred steps, but at this distance, being able to hit the back door would be a very good result.

"Get a Tianque gun!" Zhang Yang said to the guards beside him.

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

"Bang!" The firing needle hit the flint, and the splashed sparks ignited the gunpowder. The gas of the gunpowder pushed the lead bullet and turned out in the gun chamber and flew forward.

Jiao Yu was speechless when he heard this sound. There was no fuse or ignited gunpowder. How did this projectile be fired? Jiao Yu's technology is still limited to the level of the fuse gun. The muskets he developed for Zhu Yuanzhang must be ignited with open flame before they can be fired.

Zhang Yang was not finished clinking, then quickly pulled the pull rod on it, completed the loading, and pulled the trigger without hesitation. This time, the bird was aimed at the little bird that was shocked on the branch due to the fire of the musket.

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

If Jiao Yu felt shocked, the second sound completely made Jiao Yu despair. What kind of musket is this? After the first launch, can the second firing be carried out so quickly? Moreover, the accuracy is still so high that he didn't even look at where the back door was hit. It was just that the little bird in the sky had already made Jiao Yu feel ashamed.

He is not as skilled as a human being. If he hadn't come to Gaoyou Mansion and beat him to death, he wouldn't have believed that there would be such powerful weapons in the world!

Of course, Jiao Yu knew what these two continuous musket sounds meant. Quick loading has always been a problem he wanted to solve. However, he has never been able to connect the simple steps to load gunpowder, bullets, and ignite the fuse. These simple steps are completed in one step. Just pulling the pull rod on it, and it is completed? It is simply a replica of Zhuge Crossbow!

Shooting the bird in the sky made Jiao Yu sigh, he could do it, but he used a shotgun, filled with iron sand, and after knocking the bird down, his whole body was covered with iron sand, which was ruined. The bird had a bullet, just one bullet, how high the head should be! The bird flew in the sky, and it was harder to hit the cavalry on the ground!

"It's a pity that there are no wild ducks here, otherwise, I'd take a few and let Brother Jiao Yu taste wild game." Zhang Yang said with a smile, but found that Jiao Yu suddenly lifted his clothes and knelt down.

"Brother, please accept me as my disciple. I thought I was the one who knows the best of firearms, but who knew that I was watching the sky by landing in a well. When I saw my elder brother's firearms today, I realized that there were people outside the people and mountains outside the mountain. I had no other hobbies. Please accept Jiao Yu. Jiao Yu is willing to follow my elder brother and learn about my elder brother's firearm technology."

Jiao Yu's actions shocked everyone present. Shi Nai'an shook his head hard at Zhang Yang. This apprentice is not easy to accept. As the saying goes, teach the apprentice and starve the master to death. Moreover, who knows whether this apprentice will bite back? After all, he came from Zhu Yuanzhang. Who knows if he is 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 was very stubborn.

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

Zhang Yang thought about it, "It's okay if you want me to agree to be your master, but there is a prerequisite."

"Not to say one, one hundred are fine."

"You have to go with me to a place. In that place, you contribute the cannon casting technology you have mastered and create the most advanced cannon you have mastered. After that, I will decide whether to teach you the technology of the firearm. However, once you go to that place, you may not be able to get out in your life." In fact, this is also the third condition that Zhang Yang wanted to say just now. Jiao Yu is a person who can get into Zhu Yuanzhang's eyes, proving that his firearm manufacturing is indeed outstanding. If you can use it for yourself, of course, you have to dig it up without hesitation.

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

"Don't you regret it? That place is isolated from the world and can't come out for the rest of your life, so can you accept it?"

"If you can become your elder brother, even if you are in the sea of ​​swords and fire, Jiao Yu is willing to go there. If Jiao Yu cannot learn the skills of this musket, he may not live a stable life." Jiao Yu said.

"Okay, then let me go, guards, prepare the ship!" Zhang Yang said.

Shi Nai'an pulled Zhang Yang from behind and whispered: "Lord, are you really going to take him to the base?"

"Yes." Zhang Yang said.

"The base is our secret. Will there be risks when an outsider enters like this?" Shi Nai'an said. His worries are reasonable. Jiao Yu is Zhu Yuanzhang's man.

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

Zhang Yang knew more about Jiao Yu. To put it bluntly, he was a firearm fan, and he was so obsessed with love. Zhang Yang believed that Jiao Yu was a teacher, which was a true expression of love. Besides, as long as Jiao Yu was allowed to go to the base, he had no intention of letting him come out. The maze of Desheng Lake was not something that a nerd like Jiao Yu could transfer.

And the one he needed most was artillery manufacturing. Zhang Yang developed the fire gun to the extreme, which was based on his understanding of this weapon. In contrast, Zhang Yang had a relatively small understanding of artillery. He only knew that in this era, the cannon was made of bronze. The barrel was very thick and short. It was filled with gunpowder, filled with projectiles, and knocked the projectiles out. Similarly, the hit accuracy of the projectiles was very low. Unless you used a shotgun to kill the enemy in the face, it would not have much power except for the amazing momentum. It was completely different from the modern long cannon with cannons.

In the future, when conquering large cities and water battles, Zhang Yang needed artillery. Although the principles of muskets and cannons are the same, and the finer pipes are called muskets and the thicker ones are called cannons, there are still big differences when they are really built. The cannon loads a lot and the chamber pressure is large. In order not to blow up the gun barrel, the loading amount and the thickness of the cannon barrel are very particular. These things require 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 job.

Zhang Yang took Jiao Yu and followed a escort from the west of Gaoyou to Desheng Lake.

Originally, the most suitable thing was to ride a horse to the killing port and then take a boat to the base, which saved 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 had no idea where the boat was driving, so he could prevent accidents.

Of course, on the surface, Zhang Yang could not make Jiao Yu feel that he was restricting him, because Zhang Yang had been staying in the cabin and Jiao Yula's parents.

Jiao Yu was born in a family of firearms. His ancestors were alchemists. He had discovered gunpowder, and began to apply his research to the military field, such as making a fuss on a catapult, throwing incendiary bombs, poison bullets and explosive bombs, and began to try to create devices that relied on gunpowder to launch projectiles. The family has always been talented, and it has 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 musket to a stage where he could be fully put into actual combat, and he tried to cast cannons and finally succeeded.

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

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

"Don't worry, Master, even if you stay here for the rest of your life, Jiao Yu is willing to do so. As long as I can learn the master's skills," said Jiao Yu.

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

Jiao Yu didn't take it to heart. He probably was the master ringing the side bell for him. It was not until later that Jiao Yu served as the dean of the Central Weapons Academy. When he thought about it again, he realized that the master was so wise and prepared for the future.

When returning to the base, Zhang Yang had another purpose, which was to see how much the steam engine was built. Although those people started to manufacture it after their own explanation, no one had seen the real thing. It depends on their ability to understand. Zhang Yang intervened and guided it in time, which was more effective.

After the steam engine and cannon are made, they can be converted to a warship. In the south, water wars are inevitable, especially Chen Youliang, who has not yet appeared. In the battle of Poyang Lake, Zhu Yuanzhang almost gave Zhu Yuanzhang a water burial.

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

"Brother, I've been looking forward to you," Li Bosheng said. "What is this?" Looking at the white-faced scholar-like figure following Zhang Yang, there was a piece of blue on his face, Li Bosheng was puzzled.

"This is Jiao Yu. I'll bring him to the base and cast a few cannons." Zhang Yang said: "You will work together in the future. By the way, we will first transfer ten people to Jiao Yu. Forging cannons is also a physical job, and we can't do it alone."

Jiao Yu? Cast a cannon? Li Bosheng bowed: "Brother, welcome to the base. We will be brothers in the future. If you have any needs, just open your mouth 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 guns."

When Jiao Yu learned that the person in front of him was the supervisor who made the Tianque gun, he immediately replied: "I will have Brother Lao Bosheng in the future. Please give me more advice!"

"It's not enough, it's not enough." Li Bosheng said with a smile.

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

Jing Tie? Jiao Yu did not rush to reply to the gift this time, but said to Zhang Yang: "Master, we have to use bronze to cast cannons!"

Master? When did this kid become his elder brother? Li Bosheng and Lu Xing were a little surprised.

Zhang Yang said: "The cost of bronze cast cannons is too high, and the copper is softer. After using it for a long time, the muzzle will deform. Using fine iron is the best way."

Copper cannon? If I want hundreds of copper cannons, how much does it cost? Zhang Yang thought to himself that this thing cannot be afforded.

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

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

I'm not tired yet! Before Jiao Yu could say this, he was pulled away by the enthusiastic Luxing.

"Brother, is this Jiao Yu really your apprentice?" Li Bosheng asked when he saw the two of them walking away.

"Not yet." Zhang Yang said: "When his cannon is successfully cast, even if he is officially my apprentice, I promised him that after he casts the cannon, he will teach him the principle of the Tianque gun. However, before this, it must be kept confidential."

"Yes, big brother." Li Bosheng said.

"Get out a field for him and let him specialize in artillery research. At the same time, don't let him get in touch with the manufacturing of our Tianque guns, especially the manufacturing of gun barrels." Zhang Yang said.

"Is this person unreliable?" Li Bosheng asked.

"I hope I read it right," said Zhang Yang. "He was originally a member of Zhu Yuanzhang and shouldn't have brought him here, but he is really a genius in firearms. If he really surrendered to us, he could consider handing over the manufacturing of the Tianque gun to him for management in the future, and you can lead troops to war."

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

Although Li Bosheng didn't say it, Zhang Yang also knew that he was sure that he was feeling a little wronged when he saw the other brothers who grew up together fighting and making contributions, and he had been enclosed in the base and could not get military achievements. He had to make contributions to the city gate a few times before. He also wanted to make contributions to him after staying in the base for so long. It was a hard work for him.

"How are they doing in research on Li Youcai and Zhao Jiamin?" Zhang Yang asked.

"Brother, are you talking about that steam engine?" Li Bosheng said: "Since they listened to my brother's explanation, they have been working hard these days. The parts have been made and they say they are about to be assembled."

"Okay, go see them tomorrow!" Zhang Yang was very happy. He has been staying at the base these days, and can watch the manufacturing of steam engines and the casting of cannons by Jiao Yu. Recently, the army in Yangzhou has been transferred away, and Gaoyou Mansion is safe and sound for the time being.

The night gradually became deeper, and the entire base was trapped in an endless silence. Only the tired workers snore when they were sleeping, blending with the sound of the wind outside, calm and peaceful.

Jiao Yu couldn't sleep. When he first saw the huge power of the Tianque gun, he was overjoyed. The advantages of this kind of firearm were very great, simple to fill, fast, and high hit rate. If he hadn't seen it in person, he wouldn't believe in the power of this kind of firearm. He was very eager to know the principle of this kind of firearm. How did he fire it? He didn't need to ignite it! How did it load it? He didn't see anything stuffed into the muzzle. What were the two pull rods for?

Apart from joy, he was worried. The requirement for casting cannons with fine iron is very high. The same is true for making steel. However, if using the steel for making cannons, the consumption of this kind of steel is sky-high. Can there be so much steel on this island? When he came over, he seemed to see a few high devices, and I don’t know what it was. Tomorrow, we will make the mold for casting cannons, and by the way, see if there is any fine iron that meets the requirements.

Jiao Yu never thought that the master asked him to cast cannons for practical combat needs, but he just thought he was testing him, so he must cast the cannons well in order to gain a higher status in the master's heart.

He liked this feeling, much better than in Zhu Yuanzhang's military camp. He didn't come in vain. Although he was hit a few times, it was worth it. He just saw them asleep and was embarrassed to wake them up. He took them away to study and research first. They were indiscriminate, but they just came up and punched and kicked. They were really barbarians!

Zhang Yang did not fall asleep either. He was thinking about modern cannons, cannons, howitzers, tank guns, mortars, and so many kinds of cannons, but he was not very familiar with any principle, and there were more shells, armor-piercing shells, grenades...

So many things are repeated in Zhang Yang's mind. Putting aside complex superficial phenomena and pursuing the most essential things is the key to solving the problem!

Why is the Tianque gun advanced? Because it has rifled, if you want the cast cannons to have amazing power, rifle is also necessary. He could almost imagine that even if Jiao Yu casts his best cannon, it cannot meet his needs. Let Jiao Yu builds cannons, but it is just a test of his real ability.

After confirming that Jiao Yu was really a genius of firearms, he asked him to test two types of artillery. One was a longer tube, a thin caliber, and a rifle was engraved inside. It was used to launch iron shells with a layer of lead on the surface. The shells could not be round, but modern pointed shells, which reduced air resistance and increased range. This kind of artillery was mainly equipped on warships and used to attack strong cities. The surface was to allow it to be squeezed by rifle and then rotated. If it was all iron, the rifle would be smoothed out after only a few times. If it was all lead, the cost would be too high. After all, lead was a rare metal, and the lead was too heavy.

Another type is a mortar, which has a short body tube and a thick caliber, and does not need to be rifled inside or loaded with shotguns. This type of artillery is mainly used to kill and injure the opponent on the surface and equip field troops.
