The production of grenades is simple.

The medicine shop had developed the fuse that Li Yu had asked for, and now it is just in use.

The body of the grenade is cast with lost-wax cast iron, and the shape is round, with horizontal and vertical Yin lines, which looks a bit like a grenade at first glance.

It is installed with a half-foot-long circular wooden handle, the wooden handle is hollow, and the fuse is inserted inside, and the fuse head of more than an inch long is exposed outside the wooden handle.

At the other end, the fuse is inserted into the body of the bomb, which is filled with explosives.

Although Li Yu does not have a secondary detonating device such as a detonator, he can still detonate explosives, but the power is much smaller.

In the test site, a wall stood in front of Li Yu, and a torch was inserted on the ground beside him.

"Ready, light."

"Bomb dropping."

Li Yu personally lit the fuse, and watched the grenade snorting green smoke behind the wooden handle, and he threw it violently into the bomb throwing area.

"Dodge bullets!"

Everyone watching dodged and hid in the earthen wall around them.

"One"

"Two"

"Three"

"Four"

"Five"

"Six"

Li Yu expected that the time for the six-second explosion had passed, but the scene was silent, and the grenades in the bombing area did not move after a puff of green smoke.

After another five minutes, seeing that there was no movement, Li Yu ran over and picked up the grenade.

"Open the check."

The master craftsman took matters into his own hands and removed the wooden handle.

Only then did everyone find out that the fuse burned to the bottom and went out.

I'll go.

It could be an accident, come again.

So the second grenade was also thrown, but it still didn't move.

The same goes for the third one.

I took it back and checked it, and found that it was all extinguished when the fuse burned to the bottom.

The master didn't understand, Zhang Yi blinked and said to Li Yu: "Lord, are you choking?" ”

"Choking fire?"

Li Yu picked up the wooden handle and looked left and right.

"It's just that the smoke inside is too big and chokes out the fire?"

Oh, Li Yu figured it out, it's just that the air is not enough to burn!

"Make a few small holes in the side of the wooden handle and try again."

The carpenter modified it on the spot, and made a few small holes in the connection between the wooden handle and the cast iron projectile body, which were connected to the hollow pipe and used to inject air.

The modification was completed and the fuse was reinstalled.

"Ready, light."

Woo woo~~~

Li Yu threw the grenade with all his might, and it actually made a whining sound.

Six seconds later, boom~~~~

The bombing area flashed with fire, thunder fell from the sky, and smoke and dust shot out in all directions, and the air was filled with dust and a smell of burning.

The ground trembled beneath his feet.

Crackling clods of earth, stones, and shrapnel splattered in all directions, nearly collapsing the earthen wall where Li Yu was hiding, and the plopping mud smeared his head.

The thunder is lingering, and the aftertaste is endless.

It took a long time for the ears to be deaf and slowly recovered.

The sound of the pistol was already like thunder, but when compared with this grenade, the difference can be seen.

Li Yu didn't expect the grenades of the Tang Dynasty to be so powerful.

It took a long time for those present to poke their heads out from behind the earthen wall, their faces pale, and their hands and feet trembling.

Now they believe that Li Yu, the king of Germany, is the martial arts star monarch who came down from the heavens, and he has great power, and he can really destroy the world with his moves, this is what he saw with his own eyes, yes!

As for what grenades are not grenades, they are not small toys in the hands of King De! Without King De, can there be such a thing?!

Ten days later, two battalions of the Forces nouvelles and the guards began bomb throwing exercises.

This kind of training can only be done in the wild.

The earthen walls were laid, and the soldiers were trained one by one, so that the soldiers could listen to the explosion of grenades.

Although the distance between the bomb dropping area and the viewing area was hundreds of meters, the deafening explosion and the dust raised in the sky made the eyes of the soldiers in the distance blood-red, just like soldiers hearing the horn, and the bloodthirsty impulse in their hearts was stimulated.

Of course, there are also those who pee their pants.

Although I have been trained for a while in pistol shooting, and I am used to hearing the sound of gunfire, the sound of gunfire is nothing compared to the sound of explosions, and it is not on the same level at all.

Each of the two battalions dropped live ammunition three times, and in the future, the bombing training would only drop training bombs, otherwise it would really not be able to consume it.

In these three live-fire trainings, more than 3,000 grenades were consumed.

Fortunately, Li Yu is now not short of wood or iron, and even has a large inventory of gunpowder, so he dares to do this.

Because the power of gunpowder is relatively small, the body of the grenade is larger, each weighing a catty, and up to now, the distance of the grenade is about 25 meters, and the farthest is only 30 meters.

It's just too heavy.

Li Yu knows that if the current grenade is thrown by people, it can only be at this distance, but this distance is easy to hurt himself, and he has to find a way to use tools.

So he set his sights on the crossbow.

This kind of crossbow machine is not a hand crossbow, it can be carried around, this is a large crossbow machine used by the city defense, and the projection is a crossbow gun.

A crossbow gun more than a zhang long can be projected at a distance of four or five hundred meters.

Refit.

Changed the projectile ballista to the projectile grenade.

Anyway, it took six seconds from ignition to explosion, enough time for it to fly in the air.

The result was really gratifying, and the grenade could be successfully fired.

However, the most troublesome thing about the crossbow machine is not the launch, but the winding.

It takes several people to get the bowstring on properly, and because of the great force, the mallet has to be smashed open when firing.

What Li Yu needed was a field weapon, not for city defense, so the crossbow machine had to be modified.

The most important thing is to add a few pulleys to ease the difficulty of winding.

As for the launch to smash, smash it, it's not a big deal.

The carriage was modified again.

Today's carriages are two-wheeled carriages, and the carriages are not flat, high in the front and low in the back. Directly change to a European-style four-wheeled carriage, so that it is stable, and install the crossbow machine on the carriage, won't you be able to go?!

At this time, the skilled craftsmen are the stakes, and under the guidance of Li Yulian, the carriage was quickly made.

The front wheels and the car plate are movably connected and can be steered, and the rear wheels are fixed to the car plate. The crossbow machine is mounted on the board.

The base of the crossbow machine is also a movable connection with the crossbow machine, which can be rotated 360 degrees. The slabs around the carriage are half a person high, and there are wooden boxes inside the slabs, which is where the grenades are placed.

Li Yu arranged three people in the carriage, one person was dedicated to winding and aiming, one person was placing grenades and ignition, and the third person was dedicated to smashing the bracket.

The carriage also needed a coachman.

In this way, the four of them formed a bombing team.

On the field training ground, the coachman drove the carriage through the wasteland, and the three people in the carriage moved much slower on the shaking carriage, and made more mistakes.

There are often cases of grenades falling.

There were several times when the danger occurred.

Li Yu had to rebuild the crossbow machine.

A card slot is installed in the grenade placement slot, and the grenade is inserted into the card slot, so that no matter how bumpy the carriage is, the grenade will not be turned upside down.

The carriage on the training ground again was chilling.

I saw that within five breaths, the carriage threw a grenade outward, the distance of the projection was as high as more than 400 meters, and the explosion sounded in one direction of the carriage, blowing up the dust in the sky, just like Lei Gong casting a spell on land, and the thunder fell from 400 meters away, and the carriage was safe and sound.

Good, good stuff!

Not only did Li Yu smile with his eyes, but even the two battalions of new troops were dumbfounded.

How far did they throw, at most fifty steps, look at the people, at least six hundred steps or more, oh my God! Isn't this a miracle?

"Ten more thunder cars."

The carpenters of the whole Nanyang were busy, not only to build four-wheeled carriages, but also to build new crossbow machines invented by King De.

Seeing that the thunder cars were built, Li Yu excitedly took the embroidered girl Biniang to see the strangeness.

"Husband, is this what you said about the thunder car?"

"Yes."

"Can this car really thunder?"

"Of course, you can rob the thunder, and whoever comes to bully us will have to be struck by the thunder."

Two little women who were moistened by the spring love laughed and watched around the thunder car.

"Go up and have a look."

The two sisters got into the roofless carriage and looked at the crossbow machine inside.

Li Yu patiently explained how to use the crossbow machine, how to place the grenade, and how to ignite and fire.

The two girls were not interested in these things, that is, they asked curiously, and they did not pay attention to them.

If you have a minecar, you must have a minecar.

Mine cars were equipped directly to the battalion.

Each battalion was equipped with five minecarts, and twenty people were re-selected, among which the aiming hand needed good eyesight, preferably farsightedness.

This can make Fang Xing and Li Xiongle bad.

With the thunder car, who are they afraid of?

If you think about the fact that the mine car carries a hundred grenades, and five cars are five hundred, if it is equipped with a logistics ammunition vehicle, what kind of power is it?

If each person in the battalion brought four grenades, it would be two thousand, and even if they met 10,000 people, they could fight them for a while.

Five minecarts were stationed in front of the new army, and the five cannons fired in unison, raining thunder from 600 paces away, moving forward little by little with a barrage.

The new troops of the whole battalion, armed with six-turn guns, followed the carriage and rushed to the carriage under the command of the commander, trotting forward with guns.

Pressing the bullet as you walk, keep shooting forward.

In the distance, Li Yu and the officials of the national government and the royal palace all looked at the attacking team, and no one spoke.

Zhou Kuan and the others couldn't keep their mouths shut for a long time.

Such an army looks a little awkward, but why do you feel so invincible?!
