Bringing System to Great Tang

Li Chengqi knows how to use gunpowder. In addition to making big sky monkeys, he can also throw them in a catapult.

When attacking the city, the super-large catapult was erected, and the enemy could only use the crossbow and the same catapult to face off.

"Brother Yi, make a big bag, put iron and ceramic pieces in it, throw it away after a good time, and pour one piece with a bang."

Li Chengqi didn't need to introduce Li Yi, he had thought of it himself.

"The defense is good. I designed a small catapult that can steer, called a whirlwind gun." Li Yi said, turning his head.

Qing Song took out a few sheets of paper from his shoulder bag and handed them to Li Chengqi.

The tornado cannon is a small catapult that can rotate three hundred and sixty degrees, and there can be wheels under it.

When defending the city, he is condescending and has a farther range than throwing from bottom to top.

The tornado cannon has a fast launch speed, and at the same time it is easier to calibrate the direction and distance, and it is convenient and easy to use the enemy siege weapon.

This is not the whirlwind cannon that someone invented during the Three Kingdoms period, which relied on rotating centrifugal force to eject.

He was studied during the Song Dynasty to deal with enemy mobile units.

Especially the cavalry, the fixed catapult cavalry does not go there.

"This catapult is so good. The back is not a spoon, but a pocket cloth. If it is missed, it can be accurately positioned by turning it slightly."

Li Chengqi admired the drawings, which was nothing short of a work of art.

Li Longji came back a bit late for dinner at night, and there was a smell on his body, so he went to take a bath first.

The main course tonight is called Huaji. Zhuangzi kills a batch of chickens. If you don't kill them, the meat will not taste good.

The summer is too sluggish, and the egg production is not as good as the chickens of the companions, and it is on the list of ‘sounds of the gods’.

This kind of stewed chicken has less moisture and is not as hot as roasted chicken.

The Zhuangzi didn't take the method of pouring wine alive, putting condiments and other things in the wine to become cooking wine.

Then fill the chicken down, the chicken will be drunk, blood circulation at the same time, the seasoning is easier to absorb.

Instead, they kill and bleed as usual, leaving chicken blood and chicken offal.

Do not put the chicken head and claws together, and remove the chicken tip.

Then put the seasoning in the chicken belly, smear the wine, wrap the lotus leaf in the mud.

Then it is slowly heated with charcoal in a large earthen stove without digging a hole to bury it.

The top of the digging hole will take a long time to cook.

When a chicken was cracked open, the aroma came out, and Li Longji tore off two wings and a chicken thigh from the queen.

Queen Wang did not take the chopsticks, grabbed it directly, and took a big bite.

"It's delicious, I know it for the first time. You can also cook chicken with mud." Queen Wang praised.

"A lot of lotus leaves were harvested this year, and they were dried in the shade, and some greens were made into dried plums.

The people in Chang'an have a lot of income this year, and it was written in the newspaper that everyone should collect more vegetables, dry them in the sun, and dry them in the shade.

The price of salt this year is very low and will not rise in the future. People elsewhere, let's talk about it later. "

Li Yi knows that the people don't have time, and time is left in the ground.

There is a problem with the distribution of the fields. If one person gives so much, it can't be planted, and the rent is collected according to the mu.

If there are tillers, planters, combine harvesters, and small pesticide planes, it's okay, 10,000 mu can be planted.

"Third brother, Yi brother brought out good things today." Li Chengqi didn't want to think about the people's life, he couldn't help it.

"Good stuff?" Li Longji repeated.

Li Chengqi took out the drawing and showed it to Li Longji: "Knock a bag of gunpowder and put a circle of sharp things on the outside."

"Okay, can you put a wheel underneath? It's easy to move, and it can be dragged to cooperate with the troops.

Even if the infantry meets the enemy cavalry, they will have the strength to fight. If they cooperate with the cavalry, it will be even more powerful. "

Li Longji finished reading it quickly and had his own thoughts on this.

With wheels installed under the whirlwind gun, it can be disassembled, and that is a car that pulls its own.

With livestock pulling, you can also bring part of the grain and grass.

One or two can't show its effect, but there are hundreds or thousands of them that are different.

"There is a lot of saltpeter in the Shu area, so we must increase the mining effort. There are also places where livestock pens, latrines, and refining fertilizers are used.

Saltpeter has a large proportion in black powder and consumes much.

If the people all go to help gather nitrate, there can be a lot.

"Good way, I write a letter, and the court buys it from the people. Fighting is for money." Li Longji finally said a famous saying.

Gunpowder is easy to use, but it costs a lot of money.

"Brother Yi, don't sell firecrackers and fireworks for now. Keep them and use them in war."

Li Longji and Li Yi talked about the issue of strategic reserves.

"Well, the guns are not sold anymore, and Zhuangzi is not short of the money." Li Yi agreed.

If a beautiful firework can be exchanged for the life of an enemy, it would be a pity to play with it.

Black powder is actually a transitional product in Li Yi's eyes, and he can now make nitroglycerin.

As long as he wants, he can make most of the gunpowder with the help of equipment in the hospital.

But it didn't make much sense, it was enough in the black powder war, and the rest he was going to use for mining and road repair.

The role of road construction is not only trade, but also national stability.

From Chang'an to Leizhou, the road conditions are good, and the cavalry can arrive in half a month, which is completely different from the situation where the army cannot arrive in three months.

Li Longji couldn't think that his brother Yi was as good at saving people as he was killing people, and he had a lot of skills.

He was in a happy mood, thinking that there would be a lot of war weapons sent to the border.

Some were used in the city to guard against Turks, and more were carried to fight against Tubo.

Queen Wang was also interested, wiped her hands, and took a look.

"Oh, this little catapult, operated by a few people, with gunpowder, is much more powerful than a bed crossbow.

The bed crossbow only has a long range, cannot be equipped in large quantities, and is not easy to transport, especially arrows.

For this arrow, the range and flight stability are the most important. If it can hit the enemy and can’t be pulled out, it’s even better. "

Queen Wang deserves to be from a family of military generals, and she ponders this thing all day long.

Li Yi was stunned for a moment, and said: "There is a kind of arrow with wood as its feather, with a thin iron bar at the front end, which is very sharp.

Because it is a balance wing made of wood, it can fly farther. After it hits a person, the front end enters the body.

The back part will fall off and break when you pull it hard. The front part is still in your body, so you can only cut it open and use pliers to clamp it out. "

He said another Song Dynasty thing, Mu Yujian.

The body of the wooden feather arrow should be three sections, one is metal in the front, bamboo in the middle, and metal in the back, with small wooden wings.

If the back is too light~www.wuxiahere.com~ the arrow will sink, making it difficult to fly.

In the middle is bamboo or wood. After shooting a person, follow up part of it.

It is put on the front and back, pulled out, and detached. The metal in the front is in the body.

The arrow is thin, the head is hard, and it can penetrate armor.

"Uncle, draw it out, let's take a look." Queen Wang didn't want to eat anymore.

Li Yi had to find an empty table and sat there to draw the structure diagram.

There are four parts in total, the front, middle and back of the arrow shaft, plus the small wooden wings next to it.

This is the ancient armor-piercing bullet. After hitting, all the useless places fall off, leaving only the last place to penetrate.

Li Chengqi saw it and mumbled: "This, this is too shameful, good, good stuff."

Li Yi drew another kind: "In fact, this wood feather can be made into a spiral shape, flying out to spin faster and more stable, and hitting the target to increase penetration."
