Datang: Time travel in two months, wait online, hurry up!

After the iron ball was put in, Li Ke asked someone to put a lead wire into a small hole specially drilled on the barrel.

"Wait, one person will light the fuse with a match, and then immediately run towards the opposite direction of the muzzle, as far as you can, remember?"

Li Ke said in a serious tone to the soldiers in charge of operating the artillery.

Although the gun barrel has already been tested, it was the first test firing after all, and he didn't know what to do.

If there is an accident and the barrel explodes, it is estimated that these people will hardly survive.

Therefore, it is better to keep them far away for the first test to avoid unnecessary losses.

After all, every soldier in the Shenji Battalion is an elite.

It would be too wronged if the soldiers were killed in battle because of the explosion of the test gun.

"Yes, Your Highness!"

Several people immediately nodded solemnly in agreement.

These people are actually no strangers to the operation of lighting the fuse.

After all, when he was still in Chang'an City, he ordered explosives in the Zuowei Camp.

Immediately, Li Ke also led the people back dozens of steps.

This safe distance is basically enough, even if the chamber explodes, it will not cause any danger here.

"Everyone, after lighting the fuse later, cover your ears."

Li Ke then reminded the craftsmen beside him, as well as Su Dingfang and others.

"Yes, Your Highness!"

Everyone nodded, keeping Li Ke's words in mind.

Soon, those soldiers arranged for the fastest runner to light the fire.

The rest of the people also started to back away.

"ignition!"

Li Ke nodded, and then a soldier beside him waved down the command flag in his hand!

The soldier in charge of lighting the fire also lit a match when he saw the command flag waved down.

Then ignite the fuse on the cannon!

As soon as it was lit, he immediately took a step forward and rushed towards Li Ke and others.

And just a few seconds after he ignited the fuse, the originally quiet artillery suddenly let out a thunderous roar!

Boom!

boom!

There was a loud noise, and everyone felt that the whole earth was shaking!

And even if they had followed Li Ke's reminder, they covered their ears in advance.

But the sudden loud noise still made them deafen!

And they kept staring at the artillery, and everyone found that the moment the artillery made a loud noise!

The muzzle was flickering with fire, and a solid iron ball was fired towards the distance at an extremely fast speed!

If they hadn't been staring there, it would have been hard to find out!

Because the speed at which the solid iron ball was launched was too fast, it was like a black shadow, fleeting in a flash!

Then, at this time, everyone can only see a small black dot flying rapidly towards the distance in the air.

And the billowing black smoke near the muzzle!

"This"

Except for Li Ke, everyone looked at the scene in front of them blankly.

They don't understand what happened?

Is that black dot just now a solid iron ball that was put in before?

But why can a solid iron ball fly so fast, so high, and so far!

Shock and doubts were written on everyone's faces, and then they looked at Li Ke again.

Perhaps, only Li Ke can answer this question for them.

"What you just saw was the firing process of the artillery."

"The gunpowder explodes in the barrel to generate great power, and then pushes the solid iron ball out!"

"The greater the force of the explosion, the faster the solid iron ball will be launched, and the farther the range will be!"

"Of course, the material of the gun barrel must also be able to withstand the power of the explosion, otherwise it will blow up the chamber. This is why my king told you to stay away."

"It seems that the quality of the gun barrel is very good."

Li Ke knew that everyone was very confused, so he briefly explained the working principle of the cannon to everyone.

After listening to it, everyone suddenly realized!

No wonder the solid iron ball flew away at such a high speed with just one explosion!

It is no wonder that Li Ke had such high requirements on the gun barrel before. After all, the gunpowder has to explode in the barrel. If the quality of the barrel is not good enough, it will explode directly?

However, what's the use of simply launching a solid iron ball?

The craftsmen are still a little puzzled, they really can't think of the use of using the cannon to launch the iron ball.

"Your Highness, is this artillery prepared for the battlefield?"

However, Su Dingfang immediately realized that artillery is definitely a super killer on the battlefield!

He calculated in his mind, based on the weight of the iron ball just now, and the speed at which it flew out.

Once on the battlefield, it will cause terrifying lethality to the enemy!

Flesh and blood can't resist the iron ball fired from the artillery!

Will toss the river in the enemy's formation until the iron ball loses power and stops.

Therefore, he was keenly aware that the artillery made by Li Ke was supposed to be prepared for the battlefield!

"General Su really has vision!"

Li Ke glanced at Su Dingfang with satisfaction, he was worthy of a generation of famous generals.

He has never seen a cannon before, and he can immediately connect with the war just by watching the process of firing the cannon!

Thinking of the role of artillery on the battlefield, this kind of sensitivity to war is still very high.

"really!"

Seeing Li Ke nodding, Su Dingfang couldn't help but feel a little happy.

If there is such a big killer on the battlefield, then I am afraid that he can really be invincible!

Now, his only concern is how far the cannon can fire the iron ball.

"It was actually used as a battlefield!"

Hearing the conversation between Li Ke and Su Dingfang, the craftsmen suddenly realized!

They don't understand war, and they don't know what weapons are of great help on the battlefield.

So after seeing the artillery launch, I didn't think about the battlefield at all.

Now after listening to it, I realize that artillery is used for war!

And judging by Su Dingfang's reaction, it is also an extremely powerful weapon.

Maybe even more powerful than a pack of dynamite?

Anyway, in their opinion, the miraculous explosive package mentioned in the newspaper is already the most powerful weapon.

"Go and see how far the cannonball landed for the first time, how far it landed for the second time, and how far it was from the muzzle after the iron ball was still!"

Li Ke immediately arranged for someone to measure the range of the artillery.

Including the point where the shell landed for the first time, the point where the shell landed for the second time after bouncing, and so on.

This is related to the effective range of the artillery.

And the last distance at which the iron ball stops still represents the maximum range of the artillery!

Only when you know the range can you continue to adjust.

For example, if you are not satisfied with this range, then add more gunpowder.

Until the gun bore cannot bear the power of the explosion, it explodes.

Although a barrel was lost, the maximum amount of gunpowder and the limit range were obtained.

All of these will need to be known through a large number of experiments in the coming time.

After a while, the people in charge of the measurement came back.

"His Royal Highness, the first landing point is 1680 meters away from the artillery, the second landing point is 1940 meters away from the artillery, and the third landing point"

"The point where the shell last stood still was 36 meters from the gun!"

The soldiers in charge of the measurement reported the data to Li Ke one by one.

Hearing this, a smile appeared on Li Ke's face.

PS: Fifth more! .

Chapter 179 Prepare modern teaching materials!Go to sea to catch the first fish!

This data is still good, after all, it is the first time to test the gun.

The amount of gunpowder is not very much, and Li Ke is still very satisfied with this data.

The limited distance is about 2 meters, and the maximum range is 36 meters.

Li Ke estimated that this artillery will go through various tests in the later stage.

It is estimated that the effective range can reach about 3 meters, and the maximum range may reach more than 6 meters!

This data is invincible whether it is on the land battlefield or on the water battlefield!

In this era, no army can stand against this artillery!

And this is just one, once the scale of the artillery comes up.

Before the battle, the cannons are spread out one by one, and then they will fire a few rounds for you.

After these rounds of shells were fired, the opponent basically collapsed.

The same is true at sea. Once it is equipped on the Galen ship and encounters the opponent's fleet, it can be fired directly.

Aim a little, and hit the waterline of the opponent's ship.

The opponent's ship can be sunk in minutes!

It can be said that once the Galen ship is equipped with artillery.

Then the Datang navy would have no opponents at sea.

Although there is no opponent now, but equipped with cannons, it can sink all opponents without any damage to any fleet!

And it can also defeat the opponent's land power at the seaside, so that they can land calmly!

This is how foreign countries in the past and future generations opened the door to the Qing Dynasty.

"If a hundred cannons are provided to the Shenji Battalion, then 5 people will fight 10 people, it will be easy!"

Li Ke thought that if the Shenji Battalion was equipped with more than a hundred artillery pieces, even if they fought against 10 elites, they would definitely be able to easily defeat them!

By then, he will have the strength to protect himself!

"Continue to test the gun!"

Li Ke was very excited and asked people to continue to test the gun.

The next test cannon, of course, will not be so simple.
