Chapter 104 Fireworks Bomb

"Sir, do you want to wait for Li Zhen to bring the shield and try again?" Yan Shi did not forget the entrustment of Gong Nian Huai, although he thought in his heart that Gong Nian Huai wanted a shield was a superfluous move, but what Mr. said was comparable to the holy decree. Pen & Fun & Pavilion www.biquge.info

"Forget it, it's fine without a shield. Anyway, this thing, ahem, is still a bit of a sight to behold. "Originally, Gong Yi Nianhuai wanted to say that this thing was not powerful, so he gave a salute. But when I saw Wang Xiaochun standing next to him, it was easy to say, but it hurt people.

And if there is no public loss of Nian Huai, this is a great creation. You can't erase the birth of a person who is close to genius because of your cognitive level.

Just imagine, if he Gong Nian Huai stood on the same starting line as Wang Xiaochun, he could only look down and could not look down, and there was no later generation of knowledge accumulation of 800 years more than the time and space of the Southern Song Dynasty, would Gong Nian Huai still dare to stand here and point fingers?

Wang Xiaochun stood next to him and saw a lot, although he was unwilling, but it was still within the range of psychological tolerance. And the half-grown child in front of him, who was younger than himself, looked at his eyes several times, and was generally friendly, and the eyes projected later had the meaning of appreciation.

No matter what you say, Yan Zuotou calls him Mr., no matter what you say, Yan Shi is the head of this courtyard, and the deputy head is also the head, no matter what you say, this bamboo tube and these paper tubes are inspired by the drawings of this half-grown child and evolved, if in this sense, this half-grown child is his own half of Mr., it is not an exaggeration.

"Koharu, let's start!" Yan Shi walked up to Wang Xiaochun and patted Wang Xiaochun on the shoulder, "Boy, grasp the opportunity in your own hands, don't mess up, ah!" ”

Wang Xiaochun nodded, squatted on the ground, and began to make preparations before the launch.

"Hey, the irrelevant people are scattered, scattered, and if you burn your eyebrows and hair, you will become a toad." Yan Shi waved his hand and shouted to the people walking in the distance.

"Yo, head, I'm back." Li Zhen ran back all the way with a pang, followed by three people, each holding a large shield in his arms, similar to a door panel. The three door panels are put together, which is a wall, and people hide behind it, and no matter how sharp the arrow is, it can't penetrate it.

"Why did you come back," Yan Shi glanced at Li Zhen, "Okay, all over there, yes, everyone else is standing farther away, and they don't report their work-related injuries!" ”

"What a sign!" Yan Shi pushed aside the three people brought by Li Zhen to discharge the shield, and looked up at the sky with a smile.

A few cracks had broken in the dark sky, like giant eyes squinting downward.

There was a golden light in the cracks, which edged the dark clouds with gold, and the whole sky was much brighter. While everyone's attention was on the things on the ground, the rain and fog disappeared with the light wind at some point, but the air was still full of moisture, which made people unaware of it.

"Sir, this rain is just in time." Yan Shi pointed to the sky, "Look, this day is not looking at it in the morning or evening, and it is about to test the gun, and it is clear." Huh!"

Gong Nian Huai didn't know what the timely rain in Yan Shi's mouth meant, anyway, looking at Yan Shi's appearance, Yan Shi was very satisfied, and Gong Nian Huai didn't know where his confidence came from.

"Oh, it's a good rain. I'll see how this thing is assembled. Gong Nian Huai walked to Wang Xiaochun's side, lowered his head and watched how Wang Xiaochun operated.

There have already been a few heads coming over, including Meng Zhijing and Tan Hong.

Wang Xiaochun squatted on the ground with a relaxed expression on his face. I took the bamboo tube first, looked at the inside, pulled out a piece of white linen cloth from the box, held it in my hand, stretched it into the bamboo tube, rubbed it back and forth, and when I took it out again, the white linen cloth had become black. Alas, this is the disadvantage of black powder, there will always be a residue, and every time it is fired, it must be wiped once.

It's easy to make a bamboo cannon out of bamboo. The bamboo joints in the bamboo tube are first opened, and then the inner wall is polished to become a cannon barrel that can fire medicine packs.

However, it is difficult for the inner diameter of naturally grown bamboo to grow into a standard circle, so when selecting materials, one is to try to choose a more round one, and the other is to take into account not only the smoothness when polishing, but also the regularity of the inner circle.

As for the uneven thickness of the front and back of the bamboo tube, it is secondary, as long as the large-caliber end is used as the muzzle.

Wang Xiaochun handed the wiped bamboo tube to Tan Hong next to him, then picked out a paper tube from the box, opened the front cover, checked that it was correct, and then covered it.

Wang Xiaochun stood up with the paper tube in his hand, looked around, and pointed towards the courtyard wall at the end of Yong Road, "Uncle Tan, you put the bamboo tube in that direction." ”

Tan Hong listened to the teaching, and slightly adjusted the bamboo tube downward, facing the northwest direction, and the bamboo tube was tilted at a 45-degree angle. Tan Hong's hands were holding the bamboo tube, but his eyes glanced at Gong Nian Huai from time to time, and his eyes were clearly saying, boy, look, there is no door here, and you don't want to look at people through the crack in the door.

"Sir, Master Meng, please come to the back." Yan Shi saw that Wang Xiaochun was reaching into his arms, knowing that he was going to take the fire rope, and hurriedly beckoned Gong Nian Huai and Meng Zhijing to hide behind the shield.

This dodge is really unspeakable. Someone watched from afar, someone watched from afar, and he pulled Gong Nian Huai and Meng Zhijing to hide behind the shield like a frightened rabbit, this, hey, I don't have a face to see people, I am as timid as a mouse, and I am not as good as a mouse.

"Yan Zuotou, it's okay, didn't you see Tan Gongtou, the people holding the bamboo tube are not afraid, what are we afraid of." Gong Yi Nianhuai pointed at Tan Hong as if he was fine, and said lightly, as if these big lure shields were not what he wanted to come at all.

"Uh---" Yan stretched his neck, put on a new face, and said with a smile, "Mr. can do whatever he says." ”

Meng Zhijing looked at the master and apprentice, couldn't help laughing, stretched out his fingers, and shook it towards Gong Nianhuai, which was a tail finger.

Gong Nian Huai pursed his lips and smiled, shook his head, pointed at Wang Xiaochun and Tan Hong, and signaled Meng Zhijing to be quiet, don't disturb other people's work.

Wang Xiaochun shook the fire rope and lit the fire rope at the back end of the paper tube, and a puff of white smoke came out in an instant.

Among the people present, except for Meng Zhijing, who was about to cover his ears, the others were calm. Meng Zhijing looked left and right, and while others didn't care about him, he carefully put down the hands raised to his neck again.

Gong Nian Huai raised his thumb at Meng Zhijing, Meng Zhijing blushed, clenched his fist and shook it at Gong Nian Huai, snorted lightly in his nose, and turned his head to look at Wang Xiaochun.

Wang Xiaochun really held his breath, holding the paper tube in both hands, his eyes staring at the sizzling white smoke of the ignition rope, without the slightest panic.

Tan Craftsman, who cooperated with Wang Xiaochun, had two giant hands like iron tongs, holding the bamboo tube steadily, and the green tendons on the back of the hands were raised, giving people a feeling of infinite strength.

If Wang Xiaochun is a pool of lake water, Tan Hong is an iron plate, with two elephant legs on the ground, and there is the momentum of Mount Tai pressing the top legs without bending.

Wang Xiaochun saw that when the fire rope was halfway burned, he held the paper tube with both hands and aimed at the bamboo tube, raised his hands slightly, and then pressed his wrists down, let go of his hands, and the paper tube slid into the bamboo tube with a whoosh.

At the same time, Wang Xiaochun squatted down, holding his head in his hands, motionless.

Tan Hong Tan's head was still motionless, and his hands couldn't see the slightest trembling.

Gong Nian Huai was amazed, this old and young, should cooperate for the first time, look at this coordination, the psychological quality of the two goes without saying, the key is the trust and tacit understanding between the two, it is not possible to achieve it by training.

And before this, the two of them must not have been trained in this area, so it can only be trust.

Especially during the first test firing, who would dare to hold gunpowder in their arms for testing? Even if it's my own grandfather, my son can't do it, people's lives are a matter of heaven, who dares to joke. Can you pay back the money you owe, can you pay back the life?

Gong Nian Huai thought about it, and at the same time planned to ask Yan Shi after coming down, if it was the same test method when he first tested it. If so, Gong Nian Huai really has to look at the craftsmen in this small yard differently.

"Tom!" A muffled sound came, a puff of white smoke came out of the bamboo tube, the fire burst out, and a flame burst out from the front end of the bamboo tube, shooting straight out two or three meters away.

Looking at Tan Jiangtou again, his feet are like roots, and he doesn't move at all.

In fact, Gong Nian Huai didn't care about the effect of the launch, his attention was all on Tan Hong, he wanted to see how much recoil there was.

The moment the firelight flashed, Gong Nian Huai could see clearly, Tan Hong's upper body only trembled slightly, his arms sank slightly, and he quickly returned to his original state.

Like a mosquito landing on a rose branch, the flutter of the branch is not visible.

Actually, there's nothing surprising about that.

Although Gong Nian Huai did not take a close look at the bamboo tube and paper tube, he could guess eight or nine without leaving ten. The inner wall of a bamboo tube may not be a regular circle. If the inner diameter is not a regular circle, then the air leakage, the air tightness is not good, from the beginning of the gunpowder deflagration, the air leakage will begin, and the chamber pressure will decrease;

The outer diameter of the second paper tube may not fit the inner wall of the bamboo tube tightly. In order to ensure that the paper tube slides smoothly into the bamboo tube, the outer diameter of the paper tube is smaller than the inner diameter of the bamboo tube, how much smaller. Therefore, there will be a gap between the paper tube and the bamboo tube, which will also lead to air leakage.

The third and most important point is that the power of gunpowder itself is not enough, it can be used as an accelerant, and there is still a long distance to go in the middle if you want to achieve deflagration or even explosion.

Therefore, Gong Nian Huai doesn't need to deliberately look at the effect of the flame eruption at the opening of the bamboo tube, he can guess eight or nine, in fact, he can also estimate the impact force of Tan Hong.

Among these people, the busiest is not Wang Xiaochun or Tan Hong, and the most nervous and excited is not these two parties, but Meng Zhijing.

The people in the courtyard had already seen it when they tested the cannon for the first time, so they naturally wouldn't be surprised, Gong Yi Nianhuai relied on the knowledge of later generations to predict the prophet, and he could guess a rough idea just by guessing.

The only one who has never seen the world is Meng Zhijing, who should have seen the world the most, the eldest son of Meng.

Meng Zhijing's two eyes were not enough, staring at Wang Xiaochun for a while, Tan Hong for a while, and staring at the smoking paper tube for the next moment, nervous and excited, and his fists were so clenched that he could clench water.

Wang Xiaochun put the paper tube into the bamboo tube, and Meng Zhijing's limbs couldn't find a place to put it. For a while, I wanted to raise my hands to cover my ears, and I wanted to learn from Wang Xiaochun to squat down, holding his head with both hands, opening his mouth, and staring, just like a male frog hiding behind a lotus leaf to peep at the female frog urinating, and he was so excited and nervous that he didn't know what to do.
