Poor family mother and son

With the participation of craftsmen, the production of "unconscionable cannon" has become easier.

With the five taels of silver "big cake" drawn by Xiaobao first, these disabled craftsmen who have no life and are eager to settle down really want to quickly pass the probationary period and become regulars.

They even suggested that they could sign a contract of sale first. Even if their skills were not good enough to reach the level of a master craftsman, they could stay for a door-to-door and sweep the floor.

As soon as they came, they solved the problem of welding the seams of the steel plates for Chu Qing.

This was Chu Qing's most troublesome problem, because when a piece of steel plate was rolled into a cylinder, the firmness of the seam was directly related to the degree of damage caused by the explosion of the barrel when it was used as a gun barrel.

Another reason why Feilei cannons are called "unconscionable cannons" is that they are easy to explode and hurt their own people.

During the entire production process, Chu Qing only told what the thing should look like, but didn't say what it was used for.Two days later, Chu Qing took the cannon to the basin east of the Dou Iron Mine Mountain, where there was a small lake where fish could be eaten.

Chu Qing had conducted a test explosion of a grenade here before, and today he was going to test the cannon.

There were several packs of explosives that Chu Qing carried on the carriage, and they were bundled into a helmet shape instead of a round cake shape, which was more conducive to rotating and rolling in the barrel and increasing the firing range.

The explosives are all black powder prepared by Chu Qing himself, and it is not easy to tie them up. It must be tied firmly to increase the density of the black powder per unit volume, and the lead wires must be placed properly.

The fuse is the earliest method of igniting the fire twister with an open flame, so that it is convenient to estimate the time for throwing the explosive package.

The production of the fuze is also very troublesome. Instead of directly soaking the gunpowder with hemp rope and then drying it, it is used as the core, and it is wrapped with a layer of kraft paper for pasting windows, and the outermost layer is tightly wound with a layer of thin Twine burns at a speed close to one centimeter per second.

This method can guarantee that the water will not be extinguished in a short period of time, but it cannot guarantee that the strong wind will not be extinguished, but at least it can calculate the time to evacuate after ignition.

Today's test explosion is much more dangerous than the test explosion of the grenade, Chu Qing's heart was pounding.

The reason why the "unconscionable cannon" is called this name is because it is easy to explode the chamber, and the most important reason for the explosion is the problem of the lead wire of the propellant and the explosive package.

Ideally, the lead wire of the explosive package should be longer, and the lead wire of the propellant powder should be shorter, so that the propellant will deflagrate and quickly generate high-heat gas, which will eject the explosive package and explode on the ground.

However, if the exposed propellant fuse is blown out by the wind, and the fuse of the explosive package burns normally in the barrel, then the explosive package will not be able to be projected, and the chamber will explode, and the casualties will be the own people.

Or due to the angle of the barrel, the projected explosives are too close, and they will also blow up their own people.

Or, the explosive package was successfully fired, but the fuse burned too fast, and it would still blow up to its own position.

In short, it is really heartless to be a cannon and blow yourself up.

At this time, Chu Qing had no choice but to tell Master Lu exactly what he was making.

In fact, when Master Lu saw this structure, he thought it looked like a large firecracker. He even guessed that the hole dug in the elm pier at the bottom should be used to fill the fire surface, and the hole drilled next to it should be used to insert the lead wire.

So after listening to Chu Qing's words, Master Lu just blinked his eyes for a long time, and then said: "Try it first!"

Accept it well?
This time it was Chu Qing's turn to blink: "Mr. Lu, do you...have nothing to warn me?"

"What do you want to persuade? Whose girl should not carry a kitchen knife on the road when she goes out to do errands? Aren't you afraid of bad guys?" Master Lu said, his tone was full of "it should be like this".

This is where Master Lu's life in the second half of this year is not going well.

In the summer, when he met the old guys, he was already in a bad mood, and wandered all over the capital, helping the old guys treat their illnesses, and searching for other people who needed help. After spending a lot of time, he heard that Chu Qing was "conspiring against" statement.

At that time, he was so angry that he and Lao Huang Zhong were drinking and cursing, but they couldn't think of a way to help Chu Qing.

Huang Zhong was watched closely by his family, he struggled to go out, even if he wanted to see Master Lu, Master Lu was even an ordinary person, he was powerless to deal with Chu Qing.

Now that he is clearly out of trouble, what's wrong with doing something to protect himself?Isn't this the same as when a girl has to go out to do errands, she carries a kitchen knife in her bag?

Could it be that girls can only be bullied when they meet hooligans?At any rate, having a kitchen knife can also strengthen one's courage, right?
"Boom!" When the first explosive package exploded successfully, the smoke cleared, and when he saw a fish with white bellies on the surface of the lake, Master Lu knew that he hadn't thought enough - Qing girl didn't go out with a kitchen knife, but Carrying a dog's head!

"The family is big and the business is big, just this thing is not enough!" Master Lu was in shock, but disgusted in his mouth.

I can't say what it feels like, Master Lu feels that there is nothing wrong with Chu Qing's making this thing, but there seems to be something wrong.

Looking at the dead fish on the lake, Master Lu couldn't stop thinking about the moment when the explosive package fell into the water.

At that time, Chu Qing asked everyone to go to the woods to stay, and then he ignited the fuse and ran back.

Although the muzzle of the cannon was facing the direction of the small lake, the distance was fifty or sixty feet away. Master Lu felt that Chu Qing didn't need to bother to run back. He should just run to the side for a short distance, otherwise he would have to run back to see the cannon later. Canister, what a lot of effort.

In the end, the first thing I didn't expect was: actually throwing the explosive package that was used as a shell so far, I really watched it fly towards the center of the lake.

However, Master Lu also saw that at the moment of falling into the water, there was still a fire twister that was as long as a finger that had not burned to the end, so he thought that there would be no movement.

If it falls into the water before it is burned, the torch must be extinguished when it encounters water. The "cannonball" is in vain, and dozens of catties will fly to the surface of the fire.

The power should be no more than throwing a stone weighing thirty to forty catties into the water.

The second one unexpectedly happened right before my eyes: after the thing fell into the water, it exploded, and a gray-black smoke screen suddenly rose, the scene was quite frightening.

When the lake calmed down, there were dead fish on the surface of the lake, each with a whole body.

Standing together with a group of handicapped craftsmen, Xiaobao was so shocked by the sight before him that he couldn't speak. This thing is much more powerful than a grenade!

The disabled craftsmen were stunned for a while, then knelt down and worshiped together: "God, grandpa, please be merciful!"

Xiaobao: "Uh... what are you doing? It's none of my business!"

The craftsmen looked at me and I looked at you, their eyeballs were about to fly out of their sockets, and finally, they all said: "Little master, there is an old saying: 'Thunderstorms in winter, the loess piles up', this is to Dead people are everywhere!"

"Lei Dadong, nine out of ten cattle pens are empty! Nine out of ten cattle and sheep will be frozen to death!"

"and also……"

Xiaobao hurriedly waved his hands: "Stop! Did you do it on purpose? Pretend to not see that it was my mother who fired the cannon?"

"How could it be?!" The craftsmen objected: "The master is just throwing stones, how could there be such a big movement! This is clearly Dong Lei!"

Chu Qing broke into a deep sweat.

The gunpowder was loaded by Chu Qing alone without their participation, so they thought it was possible that it was a trebuchet. I am afraid that even though Chu Qing ignited the fuse, they did not think of it as a cannon?

After all, this iron bucket was placed on a pair of big wheels, a bit like a catapult, but it didn't even have a catapult stand, but the thing thrown out looked a bit like a stone.

Besides, the catapult can't make such a big noise, only the thunderbolt from the sky can make it!
