On the Nanshi Street in the north of Jixian Fang, the gongs and drums are noisy, the bustle is abnormal, the new science and technology scholars pass by here, the people on both sides of the street applaud warmly, cheer, and the young girls are affectionate, sending worship and suffocating eyes.

In front of the fanatical people, the new science and technology scholars were full of spirit, and exchanged for the glory of this moment with more than ten years of hardship.

Huangfu Weiming ranked first with the heroic posture of the new champion, he wore a silk red flower on his chest, wore a purple brocade robe, and wore a crown on his head, coupled with his big ears and blazing eyes, which made him even more radiant, so that he won countless applause and cheers.

At this time, the emperor was indeed intoxicated with applause and applause, intoxicated in great glory, intoxicated with the blossoming future, he was appreciated by the emperor, reused by the prince, and his career was bright.

At this time, the emperor who was immersed in joy felt something, and turned his head to look at a carriage dozens of paces away, which was a richly decorated carriage, with three horses, a wide carriage, a thin gauze curtain hanging from the window, and the carriage stopped against the wall, lonely at the turn of a path.

This carriage gave Wei Ming a very familiar feeling, he couldn't tell the reason, but this carriage attracted him so much that he turned back step by step, kept looking at the carriage, his eyes were full of surprise, suddenly he thought of something, his eyes suddenly lit up, and he beckoned to the carriage.

In the carriage, Wu Jin silently watched his brother through the curtain, not only happy for his high school, but also a deep regret, from this moment on, his brother finally embarked on another road, a completely different road from him, he didn't know if one day in the future, would they meet each other in a narrow way, would they turn against each other?

These Wujin don't know, but the trend is already doomed, he followed the prince, and one day he Huangfu Wujin will have a showdown with the prince, at that time, which side will his eldest brother Huangfu Weiming stand on?

"Childe, do you know him?" Jing Niang asked in a low voice on the side, they didn't come to see Jinshi Youjie, but happened to meet halfway to her uncle's house, but Jing Niang keenly felt the helplessness and regret in Wu Jin's eyes.

This is an unusual feeling, she can understand it, Wu Jin sighed, and said with a wry smile: "Did you see it?" That champion is my eldest brother Weiming. ”

"Ahh Jing Niang exclaimed, she stared at Wei Ming at the front with wide eyes, and looked back at Wu Jin in surprise, Wu Jin never told her that he also had a brother, of course she knew that this Huangfu Wei Ming was not the grandson of the king of Lanling County, but should be the brother of Wu Jin before returning to the palace.

"Childe, let's go and say hello to him! I see him waving to you. ”

Wu Jin shook his head, he pulled the curtain and looked at Wei Ming from a distance, and at this time, Wei Ming was also looking back at him, their eyes met, Wu Jin waved his hand to him, and a smile appeared on his face.

Wei Ming also saw his brother, his nose was a little sour, he also smiled at Wu Jin, slowly turned around, and continued to face the sunset, at this moment his heart was joyful at the same time, and added a trace of indescribable loss.

Wu Jin kept looking at his brother's back in the distance, he gently lowered the curtain of the car, and said to the coachman: "Uncle Wang, let's go!" ”

The carriage started, drove into the small road, and soon got on another main road, heading for Jixian Fang, which was not far away.

．．．．．．．．． Jixian Fang is also the residence of Jing Niang's uncle and aunt, for Wu Jin, Jing Niang's uncle also serves as one of his secret duties, from the last time he handed over the gun materials to Jing Niang's uncle Chen Jinsatin, during which he also came a few times, on August 25, Chen Jinjin has been made into the first sample gun, but it is not qualified, not that Chen Jin's craftsmanship is not good, on the contrary, the smoothbore gun he made is extremely exquisite, but the barrel is not qualified.

Wu Jin spent another day, through the armory shop to find an old craftsman who made copper pipes, only then did he get a qualified copper pipe, today is the second sample gun out of the day, this day Wu Jin has been looking forward to for a long time.

The carriage drove into Jixian Fang, slowly stopped in front of the house, and Ah Bao, who had been waiting at the door, flew like a child, and complained: "Sister! Brother-in-law! Why are you here? I've been waiting for you for a long time. ”

With the passage of time, Ah Bao and Wu Jin gradually became familiar, the initial shyness disappeared, revealing her cheerful and lively side, her surname is very cheerful, and she also likes Wu Jin very much, although Jing Niang reminded her several times that she was called Gongzi, but she still went her own way, calling her brother-in-law one by one, so that Jing Niang was helpless, but Wu Jin also liked her, which made Jing Niang's heart a little worry disappeared.

Jing Niang got out of the carriage and said with a smile: "I didn't let you wait at the door, what are you complaining about?" ”

"I'm not waiting for you!"

Ah Bao affectionately grabbed Wu Jin's arm, and said a little coquettishly: "Brother-in-law, did you bring me any gifts?" ”

"Yes!"

Wu Jin took two Shu brocade silks for shawls from the carriage, handed them to her and said with a smile: "You choose one for yourself, and the other for your aunt." ”

Ah Bao was overjoyed, "Thank you, brother-in-law, I know that my brother-in-law has a heart." ”

She draped a colorful brocade silk over her shoulders, and asked Wujin with a smile, "Brother-in-law, do you think I look good in this?" ”

"Hmmm! This colorful is more suitable for you, Bao, the Jinshi outside is walking across the street, why don't you go and take a look? ”

"I don't like those who read, they are all weak and uncomfortable, if it is a triumphant return of the army, I will definitely go to greet it, brother-in-law, when can you teach me to ride a horse? I've always dreamed of riding a horse. ”

Jing Niang saw that she was pestering Wujin, so she pulled her over, "Don't pester Gongzi, I have something to do today!" ”

Wu Jin smiled, "Okay! I'll teach you how to ride a horse another day, and now I'm going to talk to my uncle about something, and I'll talk to you later." ”

He was thinking about the gun in his heart, so he walked quickly into the courtyard and went directly to Chen Jinjin's piano room.

When he walked to the door, he happened to meet Jing Niang's uncle Chen Jinjin, and when he saw that Wujin was coming, he hurriedly smiled and said, "I was about to go to the front to find my son." ”

"Uncle, how is it, have you made it?"

"You come with me!"

Wu Jin followed him into the piano room, where Chen Jinjin made musical instruments, and now the family had been helped by the king of Lanling County to break away from the music book, but this also meant that they could no longer earn a living by playing.

Chen Jinjin decided to do a musical instrument business, originally he wanted to open a shop near Nanshi, but under the persuasion of Wu Jin, he decided to open a shop in Weiyang County with his family, his skill in making musical instruments is very exquisite, and it is his exquisite craftsmanship that brings Wu Jin hope of making guns.

The room is full of all kinds of piano-making materials, all neatly stacked, a few half-finished pipas are put aside, more than 20 days have passed, so far there is no finished product, Chen Jinjin almost all of his thoughts and energy are on making guns, this is his style, do everything to be perfect.

Chen Jinjin dragged out a wooden box from under the bed, placed it on the table and opened it carefully, and hurriedly placed a flintlock smoothbore gun on the red silk cushion.

Wu Jin didn't tell Chen Jinjin what it was at first, but he soon discovered that if Chen Jinjin didn't know the principle, he couldn't make a real gun at all, and a qualified gunsmith, he had to know the principle and function of the gun.

This is also the real reason why Wu Jin asked Chen Jinjin to make a gun, he can't easily reveal the principle of the gun, Chen Jinjin is Jing Niang's uncle, he can make him believe.

Wu Jin took a deep breath and took out the gun from the box, this flintlock pistol and the flintlock pistol collected in his previous life can be said to be exactly the same in appearance, the eye color is slightly different, the gun in his previous life is honey yellow, and this gun is black, and the paint has not yet dried.

The gun is three feet three inches long, the length is like a carbine, there is a copper butt, a trigger, a striking iron, a powder pool, and a piece of flint is clamped between the screw buckles on the striking iron.

He raised his gun, pulled the trigger and fired a shot out of thin air, only to hear 'Click! With a soft sound, the flint stone on the striking iron struck the snap spring, which was struck open by the flint, revealing the pool of gunpowder below, and sparks flew from the flint.

Chen Jinjin was already very clear about the principle and efficacy of this flintlock pistol, and he smiled: "Childe can go to the backyard and give it a try." ”

Wu Jin nodded, the purpose of his gun was not to collect, he had prepared gunpowder before coming, the two of them walked to the backyard, the backyard occupied a large area, there was an old locust tree, Chen Jinjin erected a finger-thick wooden board, which was used to test the gun for Wu Jin.

In this dynasty in which Wujin lived, gunpowder was already very developed, and primitive firearms such as gunpowder arrows and earth-shaking thunder had been widely equipped in the army, and Wujin had already obtained ignition and propellant from the army in advance.

In fact, the flintlock pistol is not very convenient, you need to pour the propellant from the barrel, ram the gunpowder tightly with a strip and then put it into the lead bullet, and the ignition powder is poured into the powder pool in the middle, the principle of the flintlock pistol is that the flint hits the buckle spring, and the powder pool below is exposed after the buckle spring is knocked away, and at the same time, the spark splashed by the flint ignites the ignition powder in the powder pool, and then the ignition ignites the propellant in the barrel through the fire transfer hole, and the propellant burns and explodes rapidly, and finally shoots the lead bullet.

These Wu Jin were already very skilled, and he also knew the amount of gunpowder that needed to be used, so he put the gunpowder into the barrel and the powder pool respectively, and filled it with a lead pellet, the size of which was exactly the same as the caliber in the barrel.

Wu Jin raised his gun to aim at the target ring on the wooden board, slowly pulled the trigger, and only listened to the 'click!' There was a crash, followed by a loud bang, and he closed his left eye in time, and the dazzling fire in the powder pool burst out, whether he was prepared, or was he shaken back two steps by the huge recoil, and his shoulder was sore.

Looking at the plank again, the bullet did not hit the target ring, but two inches above the target ring, and the plank was punched a hole, and the distance between him and the plank was twenty paces.

Except for the slightly greater recoil, this flintlock pistol was exactly the same as the flintlock pistol in his later life, and Wu Jin's face showed the joy of success.

Unexpectedly, Chen Jinjin shook his head and said: "Childe, I have tried it outside the city, the longest shooting distance is only eighty steps, and it is impossible to shoot through the wooden board fifty steps away, and it is also very cumbersome to fill the ammunition, and the gunpowder burns with dazzling white light, and it will burn the eyes if you are not careful, I think it is not as powerful as the crossbow arrow." ”

Wu Jin knew this in his heart that the early arquebuses and flintlock pistols were not comparable to crossbow arrows, but after improvements, such as rifling and fixed loading, the barrel could also be lengthened, and the range could also be increased, plus the proficiency of the soldiers..... Of course, there is a great difficulty in this, the rifling must be loaded with breech, and the loading from the breech must have a primer, which is not possible to make a primer in this era, and the rifling requires a high hardness of the barrel metal, which is also difficult to do.

It is estimated that rifling cannot be realized, but nitrified paper can be invented, and he knows that the Rohan people can obtain nitric acid by dry distillation saltpeter, and with nitrated paper, they can make cartridges for cartridges, and then refine the barrel and bullets, improve the loading speed and gunpowder efficiency, and also greatly increase the range.

In any case, the power of the gun will definitely surpass that of the bow and crossbow, there can be no doubt about this.

He glanced at Chen Jinjin, and a knowing smile appeared on the corner of his mouth, this person can actually make a qualified flintlock pistol at one time, he is very talented in making guns, this is a rare talent, it is estimated that Chen Jinjin's wish to open a musical instrument shop will be disappointed again.

At this moment, Jingniang's mother and daughter ran over together, and they asked in surprise, "What was the sound just now?" ”
