"The shop is topped up, and I don't know what to do." Yongmu Gong mainly explained how she came here.

It was she who went to the Li family's Zhuangzi, and the people in the Zhuangzi said that Li Yi went up the mountain.

happened to meet the people of Liulizhuang, and then everyone stopped by and came together.

"After a few days, the goods are being manufactured, and there is another thing for the benefit of the people, and I want to distribute it from the shop."

Li Yi seemed very happy and sent someone to find Wang Xing.

Wang Xing ran over, looked at a large group of people, and said Li Yijiao's words to Li Longji, and the main hall could be used by Li Longji.

Princess Yongmu is naturally the main hall and the side palace, and they can live in the side hall.

Send a mandarin duck pot again, move it to another place to eat, and Li Yi will follow, regardless of the ministers.

"The gun you tried, but it still works?" Li Longji first soaked a piece of frozen tofu and soaked it in the half of the chicken soup.

The little one sat on a high chair with a small soup cup in front of him, which he drank carefully with a spoon.

Taohong and the others stood around, plus Xiaolan, and Song Jing was taken care of by the people from Huaqing Palace.

"Data is being collected, and the scale is engraved for Zhaomen, 30 zhang can break the iron armor, 60 zhang can break the leather armor, and 100 zhang can be injured without armor.

Correct! After 30 zhang, the head is lowered, and it is necessary to rely on intensive shooting to hit people.

The reload speed is still too slow for the infantry, and I have a three-stage ......"

Li Yi came up with the three-stage strike tactics that only firearms had in the Ming Dynasty.

As soon as he explained, several people understood that it was very simple.

"If you defend a city, you can have someone else help you reload, and the number of guns and the number of people you load determines the frequency of shooting." Li Longji still thought about guarding first.

When the weather is warm, a large amount of cement will be sent to the border to build the city wall.

There are many people's wives, and the cavalry harasses and restrains the Tibetan troops, and they can start a city in half a month and build the city forward.

"Brother Yi, can you first build four forts to repair the city, and connect the forts with walls?" Li Longji figured out a way to repair the city.

Build four cement forts, have protection, and then use the city wall to connect the four forts, which is safer than directly repairing the city wall.

Li Yi helped pick up the frozen tofu that had been melted away and put it on the big plate in front of the little guy, and made a blowing motion.

The little guy lowered his head and blew on the frozen tofu, blew a few times, turned it over with chopsticks, and blew again.

"Third brother, I have a diagram of building a four-sided square city into a diamond-shaped building with a convex."

Li Yi turned his head, and Qing Song opened the box and took out something.

Li Yi drew a map of the Lingbao fortress, which looked like a sharp one on the plane.

"Third brother, the enemy is attacking the city, and he can only set up a ladder along the diamond-shaped wall, and the one above can be hit down, and the one next to him can also be hit."

Li Yi handed over the map, such a fortress has a larger defensive area than the siege area.

The besiegers who climb any wall will be hit by the people behind the wall, and at the same time face the rolling wood thunderstone above.

What if you send more soldiers into the recessed place and attack all the surrounding positions, and the catapult smashes one piece at a time, and the catapult throws down the explosive pack?

If you have the time, dig out a moat of the same edge shape, and the enemy will be a problem to fill the river.

Isn't there a gun? The range is longer than that of a normal bow and arrow.

Li Longji's fingers moved along the line: "If the gun hits far, you can raise rows of buildings on the city wall, and the wooden frame is sufficient." ”

He was talking about the arrow towers, one layer at a time, which were used to shoot arrows intensively downward.

It is made of wood temporarily, like a grandstand.

When the enemy attacks the city, it is necessary to charge under the rain of bullets.

"If you change it to a big city, you can also build an urn city later." The queen looked and looked at a few places, the easiest places to attack head-on.

Add an urn city behind there, break through the wall in front, and rush in, still facing attacks from several directions.

Li Yi nodded, the big city does have an urn city, Chang'an does not, and Chang'an has an imperial city.

However, when the enemy hits Chang'an, it is already considered a defeat for the Tang Dynasty, and Chang'an has been occupied more than once in history.

"Okay, the border pass should be repaired to hide a diamond-shaped city with 5,000 soldiers." Li Longji decided to come down.

A thousand people are arranged in the city, and the weapons are ready, and the enemy army of 10,000 does not want to rush in.

Siege engines, mobile turrets, a problem with explosives packs.

Using a bow to shoot downwards, the person needs to expose a large area of the body, and will be shot by the archers under the city.

Changing to a gun, there is no need to draw the bow, and there is no need to adjust the attitude, just aim.

"Third brother, leave the hole involved in the gun, oblique, and you can swing it left and right by an amplitude." Li Yi picked up the pen again to draw the drawing.

He drew the firing hole of the turret, like a square bucket, mounted horizontally on the wall, and the gun could swing from side to side when extended.

There are arrow holes in the current city wall, but the holes are relatively large, and the enemy can shoot them if they are accurate.

Replace it with a small one, and the enemy will stare dryly.

You can make more shooting holes to facilitate the transfer back and forth.

The queen thought for a moment: "If you make a hole diagonally downward, you need to throw a clay pot filled with gunpowder in some places, light it and slide it down." ”

What she thinks about is standing and throwing it, it is easy to be hit from below, and the jar in her hand is burned, what should she do if she blows up her own people?

"In the future, we must focus on firearms."

Li Longji was not in a hurry to think of a lot at once, the gun was handed over to the soldiers, and the soldiers would adjust it according to the actual situation.

One night passed, and the morning dawned.

Today is still eating steamed buns, and Li Yi is ready to fly.

He ate only one bun and one boiled egg and went outside with the crowd.

The four of them seem to be in good spirits, but Bi Gou always rubs his shoulders, and obviously has not fully recovered.

When he got to the big open space, a horse was ready, and Guo Ziyi stood beside the horse.

An unpowered delta glider was pushed over, and Li Yi carried an umbrella bag and hung a hanging bag.

When he flies, his feet need to be put into a hanging bag and pulled to save his strength.

In fact, you can fly without a sling bag, and it is difficult to grasp a walking stick in the back, especially when you use your big arm and small arm to move to adjust the paraglider.

The key place is the buckle with the quick release, even if you can't break free from the hanging bag, you can open it as soon as you pull it.

Li Yi stood up, tied the rope, and looked for the direction of the wind.

He wants to take advantage of the strong wind to fly a little higher, turn around and fly back again, he doesn't want to go down the mountain.

The rope in front was tied to the saddle, everything was ready, Li Yi put on the windproof goggles and gave Guo Ziyi a thumbs up.

Guo Ziyi rode his horse forward, Li Yi followed behind with his legs upside down, ran less than ten steps, and the glider flew into the sky.

Li Yi bit the live buckle of the rope in his mouth, tilted his head, the buckle opened, and the big kite was freed.

He pulled upwards against the oncoming wind, his body moving back and forth, and the glider flew higher and higher.

The people below held the binoculars and watched nervously, afraid that they would suddenly fall.

Li Longji even regretted letting Li Yi demonstrate, what should I do if I fell to death in Datang?

"Come on, come on!" Xiaolan couldn't help but shout, she couldn't help much.

Princess Yongmu's hand holding the binoculars was sweating, her little mouth was open, and she felt like she was in the wind, and she was struggling to breathe.

Li Yi in the sky is slowly adjusting, turning, large arc, and controlling the wind side of the glider.

Begin to move diagonally and drop in height, then adjust, and again to the headwind angle, the glider rises.

As long as the wind is strong enough to keep blowing, he can always fly, but not anywhere else.

If he takes off with a tailwind, he can only descend all the way.
