Li Yi was relieved of Xiaoqin's matter, and turned his head to be embarrassed about the matter of making cannons.

Cannons can be made, but how can cannonballs be made? The range of more than ten miles cannot be reached.

To build a cannon, you have to transport, and a cannon is very heavy.

"What kind of cannon can be made well, and shells can be made well? Flying far? ”

Li Yi muttered and looked up the information to see what cannon was suitable for the current technology.

After checking around, he found that either he made a large one, and then he slowly made the fuse himself, and then the craftsmen worked hard to process the shells by hand.

Including additional gunpowder, ordinary black powder simply could not fire the shells that far.

With the seals, how many guns can be built in a complete set?

Li Yi sneaked to the workshop with his head down, wanting to ask the craftsman.

He's blown it out, and it's a question of how to do it.

"Lao Zhang, how do you say that you can make the exploding thing fly farther." Li Yi walked to the place where the bullets were made, and was responsible for assembling the bullets.

Lao Zhang's name is Zhang Guan, and Zhang Guan rests at the door.

The people who make and assemble the gunpowder change the place every day to let the dust that may have been in the room fall down, and at the same time open the door to supply the air.

Zhang Guan thought that the proprietor was testing himself, and smiled: "It's simple, isn't the Sky Monkey on the car?" Put it in a tube, the tube is a little longer, like a firework tube.

If you seal it well, you can fly far, but the barrel should be strong, and it is best to get the rifling wire out of the car, and use a little lead on the monkey.

Increase the propellant thing, and launch the Sky Monkey like a bullet, if the fire dragon comes out of the water like a second-level one, it is estimated that it can hit five or six miles. ”

"A mortar that can fly some distance yourself?" A picture appeared in Li Yi's mind.

The Sky Monkey adds a primer, the pipe is like a gun barrel, and the back position is used with lead and cork, and the Sky Monkey is beaten out at once.

The Sky Monkey spun and flew like a bullet, and was ignited during the flight, and after the second stage was ignited, it was able to fly far away.

Is this an extended-range rocket?

The primer is launched, and the Sky Monkey flies out for a distance and is ignited by the slow lead, spitting fire, flying to a certain extent and gliding in the air by inertia, and then igniting again.

The disadvantage is that there is less explosives that can be loaded, the chamber needs to be cleaned, and the slow ignition of the lead is a problem.

When firing, a small control is needed to ignite the lead inside the Sky Monkey, and all of a sudden, the pressure in the barrel of the cannon is large, and it may directly rush all the places where the slow lead is located.

As soon as it came out of the muzzle, the rocket erupted into fire.

"No, it's too difficult to manufacture." Li Yi shook his head in denial.

"Lengthen the Sky Monkey and put it in the tube, how can you make a four-mile trip." Zhang Guan thought about it and felt that the proprietor was right, the process requirements were too high, so change one.

"Okay, make a tube, use iron, the weight of a tube should be controlled within fifty catties as much as possible, it can be disassembled and assembled, and I will go back to draw."

Li Yi decided, so he built a rocket artillery barrel and used it to launch a long sky-channeling monkey.

He thought of the barrel of his domestically produced 07-millimeter rocket launcher at that time, which was very light, the shells were also light, and the operation was simple.

Even so, he couldn't make this kind of rocket, so he could only launch the Sky Monkey.

The barrel that can be disassembled should not be too heavy, and it is good for people to carry the kind that can walk.

A horse can carry two, one left and one right.

He went back to the study, drew the drawings in half an hour, and looked for Li Longji first.

"Third brother, look at this line, the distance is closer, four miles, and the Yellow River is not wide."

Li Yi blushed a little when he said it, it was blown up before, unless he exchanged it directly, otherwise he couldn't make a cannonball that hit ten miles in a month.

"Ten miles can't?" Li Longji was still worried.

"It's too heavy, a few thousand pounds, it's better to be a monkey." Li Yi told the truth, isn't it just a cannon, gritting his teeth, specially made, yes.

How do I use it after I finish it? Thousands of pounds of things can only be pulled by horse-drawn carriages, and the road is not easy to walk.

There is a technology for making artillery shells, which is not as good as making copper bullets, with a primer, so that a machine gun can be produced.

Li Longji thought about a big iron barrel and a group of people transporting it, and frowned: "Is there anything else?" ”

"I need to come up with better gunpowder, mortars, not small, lightweight, and long-range."

Li Yi knew that there was a good thing, but the technical difficulty was high.

Li Longji understood: "It's too powerful to be used, can the Sky Monkey add a tube to hit farther?" ”

"The accuracy can also be improved, and the manufacturing process of the monkeys has been improving, and every monkey is almost the same." Li Yi scratched his head.

"How do you do the second kick on the Zhuangzi? Add it in and put it behind the monkey. Li Longji gave an idea.

"The tube should be thickened, and it is estimated that it will be more than 200 catties, which is the size of a monkey." Li Yi calculates the explosion pressure of the two kicks.

"You make some small, thin, two kicks in the back, add a section of the Sky Monkey, and put the tip of the arrow in front of the Sky Monkey, for example, it can hit a mile of ground."

Li Longji still has ideas, who said that you have to blow up someone?

A large number of small tubes, equivalent to arrows with a long range, are fired intensively at a distance of 200 paces, what enemy can withstand?

If you can still leave some gunpowder to explode, the arrow enters the body, and then explodes, even if the two kicks are attached to the body and exploded, can it be blown up?

"Good way, the third brother is amazing." Li Yi stretched out his thumb.

He thought about it for a while, and he felt that if the Sky Monkey with arrows that didn't need to fly too far could explode, the biggest effect would be psychological pressure.

Being shot by this kind of arrow is already very uncomfortable, and if you have to bear the boom again, can the battle still be fought?

"I'll draw a picture and do the math." Li Yi turned around and gave the drawings to Ziyu, who was standing in the nearest position, and he ran back to the study by himself.

Ziyu shook the stack of papers in Qingsong's hand, smiled, and looked up at the sky.

Qingsong jumped forward in two steps, grabbed the drawings in the hand of Ziyu, and ran away.

Ziyu: "......"

"The proprietor gave it to me, let me send it, right? You've seen it all. Ziyu looked at the others.

Everyone shook their heads together, meaning that you don't say it, the proprietor gave you something, you can actually ask others to rob it, what is the consequence of the person who sent the information being robbed?

"Your Majesty, they all bullied me." Ziyu said to Li Longji.

"Otherwise, next time I change to a purple jade, I will protect you." Li Longji said lightly.

"Your Majesty, I was wrong." Ziyu almost knelt down and wanted to remove herself from the list, and she couldn't live.

was kicked out of the group of eight, which means that the proprietor Li was upset, and since this is the case, everyone can be bullied.

Li Yi's painting there is what the Song Dynasty has, rockets, monkeys tied to arrows, but that one does not explode, only increases the range.

Of course, even with rockets, the Song Dynasty still did not fight the enemy, destroying one after another, and finally the Great Song Dynasty became the Northern Song Dynasty.

Then there was the name of the Southern Song Dynasty, and the history of the dynasty appeared.

The technology of manufacturing weapons is good, but it cannot withstand the strong cadres and weak branches, and the emphasis on literature and suppression of force.

"Okay, that's it, don't tie it, plug it directly into the front, add a cover made of bamboo, control the balance during flight, and divert the air. It's called a fairing. ”

Li Yi also drew the drawings of the rocket.
