Li Yi was relieved about Xiao Qin's matter. He turned his head and was troubled by the problem of building cannons.
He could build cannons, but how could he build cannonballs? He couldn't reach a range of more than five kilometers.
He still had to transport the cannons, and a cannon was very heavy.
"What kind of cannon can I build? Is it easy to build cannons and cannonballs? How far can they fly? "
Li Yi muttered as he searched for information to see which cannon was suitable for the current technology.
After looking around, he found that he could build a big one, and then he could slowly make the fuse himself, and then the craftsmen would work hard to craft the cannonballs by hand.
Including other gunpowder, ordinary gunpowder couldn't launch the cannonballs that far.
How many guns could he make with the whole set of cannons?
Li Yi lowered his head and strolled to the workshop, wanting to ask the craftsmen.
He had bragged, but how to do it was a problem.
"Old Zhang, how can I make the explosive things fly further?" Li Yi walked to the place where the bullets were made. This place was responsible for assembling the bullets.
Old Zhang was called Zhang Guan, and Zhang Guan was resting at the door.
The people who made the gunpowder and assembled the bullets changed places every day to let the dust that might have been in the previous room fall down. At the same time, they opened the door to let in air.
Zhang Guan thought that Dongzhu was testing him and laughed: "Simple, isn't the Sky Monkey mounted on a car? Put it in a tube, and the tube is longer, like the tube of a firework.
Seal it well, and it will fly further. However, the tube has to be sturdy, and it's best to use a bit of lead on the Sky Monkey.
Add the gunpowder and launch the Sky Monkey like a bullet. If it's a level two one like Fire Dragon Out of the Sea, it can probably shoot five to six kilometers. "
"A mortar that can fly a certain distance on its own?" A picture appeared in Li Yi's mind.
The Sky Monkey added primer, the tube was like a gun barrel, and the back was covered with lead and a cork to shoot the Sky Monkey out.
The Sky Monkey spun like a bullet and was ignited in the process. After level two ignition, it could fly very far.
Was this an extended-range rocket?
After the primer was fired, the Sky Monkey would fly a certain distance and be ignited by the fuse. It would spit fire, glide in the air to a certain extent, and then ignite again.
The drawback was that it could only hold a small amount of explosives, so it needed to be cleaned. At the same time, slow ignition of the fuse was a problem.
During the firing process, a small control was needed to ignite the fuse inside the sky-scraper monkey. With a loud bang, the pressure in the barrel would be so great that it might directly blow up the fuse.
As soon as it left the muzzle of the cannon, the rocket began to spew fire.
"No, it's too difficult to make." Li Yi shook his head.
"If you put the Lengthened Sky Monkey in a tube, you can at least shoot for 4 li." Zhang Guan thought for a while and felt that Dongzhu was right. The requirements of the craftsmanship were too high. He should change it.
"Okay, make a tube. Use iron. Try to control the weight of a tube to less than 50 jin. It can be disassembled or assembled. I'll go back and draw the blueprint."
Li Yi decided to build a rocket launcher and use it to launch long skyscrapers.
He thought of the 107 mm rocket launcher that he had made back then. It was very light, and the shells were also very light. It was easy to operate.
Even so, he couldn't make this kind of rocket. He could only shoot it at the sky.
The cannons that could be disassembled couldn't be too heavy. It would be good if they could be carried by a person.
A horse could carry two people, one on the left and one on the right.
He returned to his study room and drew the blueprint in half an hour. He looked for Li Longji first.
"Third brother, do you think this will work? It's a short distance of 4 li. The Yellow River is not that wide."
Li Yi blushed a little when he said this. He had boasted before. Unless he directly exchanged for it, he wouldn't be able to make a cannon that could shoot for 5 li in a month.
"Can't it shoot for 5 li?" Li Longji was still thinking about it.
"It's too heavy. It's a few thousand jin. It's not as good as a sky-scraper monkey." Li Yi told the truth. It was just a cannon. He gritted his teeth and made it.
How would he use it after making it? A few thousand jin cannon could only be pulled by a horse carriage. The road was not easy to travel.
If he had the technology to make a cannon, he might as well make bronze bullets with primers. That way, he could make a machine gun.
Li Longji thought of a large metal tube that could be transported by a group of people. He frowned: "Is there anything else?"
"I need to make better gunpowder and mortars. They are powerful, light, and have a long range."
Li Yi knew of something that was not bad, but it was very difficult to make.
Li Longji understood: "If it's too powerful, you won't be able to use it. Can you add a tube to the sky-scraper monkey and shoot further?"
"The accuracy can also be improved. The craftsmanship of the sky-scraper monkey has been improving. Every sky-scraper monkey is almost the same." Li Yi scratched his head.
"How do you make the second kick on Zhuangzi? Add it in and release it behind the sky-scraper monkey. "Li Longji gave an idea.
"The tube has to be thicker. It should be more than 200 jin. The sky-scraper monkey is huge." Li Yi calculated the pressure of the second kick.
"Make some smaller and thinner ones with the second kick at the back. Add a sky-scraper monkey and place an arrow tip in front of the monkey. For example, it can shoot for 5 li."
Li Longji still had other ideas. Who said that one had to use explosives to fight?
A large number of small tubes was equivalent to arrows with a long range. At a distance of 200 steps, if they were fired densely, what enemy could withstand it?
If there was still some gunpowder left, the arrows could enter the body and then explode. Even if the second kick was attached to the body and exploded, could it hurt the enemy?
"Good idea. Third Brother is amazing." Li Yi gave him a thumbs up.
He thought about it and felt that if the sky-scraper monkey with arrows could explode without flying too far, the biggest effect would be psychological pressure.
It was already very uncomfortable to be shot by this kind of arrow. If they had to bear the explosion, how could they continue fighting?
"I'll draw and calculate." Li Yi turned around and gave the drawings to the cub, who was standing closest to him, before running back to the study.
The cub shook a stack of papers in its hand at Qing Song, smiled, and looked up at the sky.
Qing Song jumped forward, grabbed the drawings from the cub's hand, and ran away.
The cub was speechless.
"Dongzhu gave it to me and asked me to deliver it, right? You all saw it. "The cub looked at the others.
Everyone shook their heads together, meaning that the cub should stop talking. Dongzhu gave it to the cub, yet the cub let others take it away. What would happen if the person who delivered the information was robbed?
"Your Majesty, they're all bullying me," the cub said to Li Longji.
"Why don't we change to another cub next time? I'll protect you," Li Longji said lightly.
"Your Majesty, I was wrong." The cub almost knelt down and removed itself from the list. It could not live.
Being kicked out of the eight-person group meant that it had angered Li Dongzhu. In that case, everyone could bully it.
Li Yi's drawings were from the Song Dynasty. They were fire arrows, sky-scraper monkeys, and tied arrows, but they did not explode and only increased the range.
Of course, even with the fire arrows, the Song Dynasty still could not defeat the enemy. They destroyed one enemy after another, and in the end, the Song Dynasty became the Northern Song Dynasty.
Then there was the name of the Southern Song Dynasty.
The technology of making weapons was good, but it could not withstand the strong suppression of the weak and the emphasis on literature.
"Okay, this is it. Don't tie it. Just insert it directly in front and add a cover made of bamboo to control the balance during flight and distribute the air. It's called a fairing. "
Li Yi also drew the drawings of the fire arrows.
