Pablo's eyes were in a mess, and he couldn't calculate the relevant data for half a day. Although he is an immodest prodigal son, in front of Sun Yuan, the gold master, he still has a little trouble getting over his face.

He strode forward, and nothing else, stood in front of the cannon, stretched out his right hand and gave a thumbs up, looked at it roughly, and tinkered with the cannon for a long time.

Then he took the long pole for ignition, lit it in the brazier, and put it on the cannon door.

There was a "boom", and a large cloud of white smoke filled the air.

But I saw that the brass four-pounder gun stepped back slightly, and a swarthy solid cannonball drew a graceful arc in the air.

The sharp whistling sound made people's scalp tingle suddenly, Fei Hong and the others beside Sun Yuan were also old musketeers, and I don't know how many similar gun screams I had heard before. But they didn't expect this brass cannon to be so loud, and they all subconsciously shrank their heads.

In just a few moments, the shell landed exactly in the white gray circle a mile ahead.

There was another loud bang, and the dirt, sand and gravel splashed more than a meter high, which was really powerful.

But this is not the end, the potential energy of the solid cannonball after landing is not exhausted, it bounces on the ground, and flies out several meters away, hitting two small trees in one breath before disappearing

。

The branches and leaves flew sideways, and the crackling sound resounded in the woods for a long time before the trees rumbled and fell.

"This power, this power...... What would it be good to fall into a neatly arranged military formation...... "The officers all opened their mouths wide and couldn't stop snorting.

"Good!" Sun Yuan didn't expect that the cannon of the seventeenth and eighteenth centuries would be so powerful, and he couldn't help but stretch out his palm and pat the shoulder of the donkey next to him.

"Not bad, not bad, really good!" Fei Hong, who has always been an old man, also grinned: "General, although the last general served in the firearms battalion before, this is the first time I have seen this kind of powerful artillery, and it is nothing more than the Hongyi cannon." ”

"I'm afraid it can't be compared, isn't the Hongyi cannon going out with one shot and eroding ten miles?" Sun Yuan was in a good mood and couldn't help but joke: "In my opinion, this four-pounder cannon has a range of only a few hundred meters, and one and a half miles is considered the end." ”

Wolf next to him suddenly became unhappy: "My lord, the maximum range of the so-called Hongyi Cannon is only one and a half kilometers. Moreover, the effective firing range is only 500 meters. Moreover, this kind of cannon is a ship-borne cannon, weighing two tons, and your Ming Dynasty's use of this kind of cannon in field battles is simply chaotic. With such a heavy artillery, how can you march and fight? ”

"Only 1.5 km range?" Sun Yuan was taken aback: "Won't it?" "I have long known that it is bragging for the Hongyi cannon to go out and erode ten miles, but I don't want the cowhide to blow so big.

As he spoke, Pablo gave a loud order: "Attention the whole team, target 031, gauge 6-20, direction to the left 30, grenade, delay fuse, number two loading, put!" ”

"What do you call a grenade?" The donkey asked curiously.

This Sun Yuan knew: "It's a flowering bomb." ”

As soon as the words fell, there was another boom, and this time the smoke from the cannon was even bigger, and the eyes were already white, and the air was full of the choking smell of gunsmoke.

The cannonballs flew over the left side of everyone's heads with a piercing scream, to be honest, since Sun Yuan crossed over to the Ming Dynasty, he could be regarded as having participated in several general battles and had seen the artillery of the Ming army on the battlefield. However, most of the Ming troops in this era used solid shells, and most of these shells were used to attack fortified positions, and they did not have much effect on the infantry, but were more of a psychological deterrent to the enemy.

In his opinion, the shell had to explode when it hit the ground

。 Otherwise, it wouldn't be a big slingshot. Building a trebuchet is much less than building a cannon.

I don't know how powerful this cannon is?

It's a pity that there is a white expanse in front of me, but I can't see clearly. There was no place to live, there was another muffled sound in front of him, and the firelight flashed out, and the officers of the Ningxiang Army subconsciously shrank their bodies again.

When the explosion died down, everyone looked up at the same time to catch the explosion.

Strangely, the lime-circled sign on the opposite hillside could not be found.

At this time, Pablo shouted: "Yes, direct hit, clear the chamber, hurry up!" ”

As soon as he finished speaking, a gust of wind blew, blowing away the smoke in front of him. The scene ahead suddenly became clear. However, there was a messy area of loess on the hillside, as if it had been gnawed by a dog, and the contrast with the wild grass next to it was strong.

"Oh, it hit the target!" Everyone woke up like a dream, either the grenade fell too close to the ash circle, and the dirt from the explosion covered the lime marker, or it hit directly and completely shattered the target.

"It's so powerful, if it falls into the crowd, it's okay!" A burst of cheers was accompanied by excited applause.

"Clear, forward!" Just when everyone was happily hammering each other's chests with their fists, the Portuguese mercenaries gave the order again.

The eight gunners quickly cleaned the chamber of the gun, suddenly put the gun carriage away, dragged the big trot and ran forward.

This sudden scene made Sun Yuanzhang Er King Kong confused, and couldn't help but ask loudly: "Pablo, what are you going to do?" ”

Pablo carried a basket of shells on his back, and replied in stiff Chinese as he ran: "Artillery is the enemy's first target on the battlefield, and it must be moved at any time." Moreover, the artilleryman had to fire close to the enemy's chest, my lord, do you know what it means to put a bayonet on a cannon? ”

"Let's go, follow along!" As soon as Sun Yuan waved his hand, more than a dozen generals followed him to chase the cannon.

After running for more than 500 meters, the cannon had already reached the bottom of the hillside, and it was only 30 meters away from the target. Swinging it out and loading it with propellant, Pablo took out a strange-looking cannonball from his back basket, took it himself, solemnly stuffed it into the chamber, and compacted it with a long wooden pole

。

It is not actually accurate to say that it is a cannonball, strictly two iron pellets the size of a human head, connected to each other by a chain of one meter.

Seeing this strange cannonball, everyone was confused. Wen Laosan couldn't help but ask, "What is this, chain hammer?" ”

"It's not a chain hammer, it's a chain bullet, which is used on naval guns."

Before the words could be spoken, Pablo was already on fire.

His target this time was the grove next to it, and in the sound of the cannon, he saw a cannonball with iron balls connected to both ends rising into the air, twisting and waving in the air, and falling into the grove in a strange trajectory.

Bang bang bang, squeak, squeak, squeak, bang...... Countless unheard sounds struck, only to see that the row of trees with the thickness of the mouth of the bowl was cut off and smashed by the hammer.

There were flying branches and white sawdust in front of him, and the power of this cannon even overshadowed the flowering bomb just now.

"Oh my God, what if this cannon falls into the crowd?" Wen Laosan finally screamed.

Sun Yuan was also shocked with goosebumps on his body, and when he looked back, all the Ningxiang generals had sweat on their foreheads. Yes, if this cannon falls into the crowd, if nothing else, this meter-long iron chain alone can turn into a sharp knife, cutting everything in front of it in half.

As far as he knew, chain bombs were used in naval battles to tear apart enemy sails and depower enemy ships. I didn't expect this Bablo to use it in the field, and this mercenary who was a hanger was really clever. That alone is worth paying him so much every month.

Next, Pablo gave everyone many surprises. Solid shells, flowering grenades, chain shells, grape shells, and many unnamed shells alternately fired, destroying a grove of trees. And the eight artillery men were also sweating profusely from this high-intensity fire, and some of them were already shirtless.

A four-pounder infantry cannon was played with in this Portuguese boy's hands.

In the blink of an eye, more than 30 cannons were fired.

Snowflakes fell one by one, falling on people, and on the cannons that were hot, raising layers of white gas.

There were so many surprises today, and everyone couldn't stop applauding and cheering, and they were in a strong euphoria from beginning to end

。

This is a cannon, if there are one or twenty of them, swinging them on the battlefield, then it will be fine.

Whether it's a slave or a thief army, as long as you dare to rush up, we will shoot the damn with cannons.

"Alright, alright!" Seeing that Pablo had hit all the shells he had made, and that he had no intention of stopping, Wolf hurriedly shouted to stop: "That's it for today!" ”

The donkey was looking into the alley, and suddenly became unhappy: "Erhu, you devil is really disappointing." The Chinese New Year is coming soon, and our Ningxiang Army is equipped with a large number of firearms, and firecrackers are prohibited in the army. Now I can finally hear it, how can I miss it. Brother Ba, you continue. ”

Wolf was a Prussian, and the greatest merit of the Germans was seriousness, and when he heard this, he immediately shouted angrily: "The main purpose of today is to experiment with new guns, and it is not a fixed installation." If you still fight, if you continue to fight, the copper cannon will be deformed at high temperatures, and I still need data to measure. If the cannon is scrapped, it will take a lot of time to reforge a one, are you responsible? ”

Hearing Erhu's scolding, and saying that the cannon would break if it continued to be fired, the donkey was startled and hurriedly closed his mouth.

Indeed, although the four-pounder infantry gun is made of brass as the material, it is not easy to explode, but the copper is too soft. The high temperature of the gunpowder explosion with each shot causes the chamber to expand, and the shooting accuracy and range drop very quickly, which is too short for a weapon.

This problem can not be solved until the emergence of high-quality steel in modern times.

However, as far as Sun Yuan knows, even the barrels of modern cannons don't seem to have a long lifespan. For example, in the modern Type 98 main battle tank, the barrel life seems to be only a few minutes, and it needs to be replaced after hundreds of rounds.

This is true of modern artillery, not to mention the bronze cannons of the late XVII century.

Pablo had already fired more than 30 cannons just now, and the barrels were all red. If you fight again, it is estimated that this infantry gun will not be able to support it.

Sun Yuan: "It's okay, it's okay, Erhu, this cannon is really good, when can it be officially installed?" ”

"It's early, I've got to experiment a few times, it's very early." Wolf snorted unceremoniously: "I'm not Father John Tang, get some garbage out to fool you Ming Dynasty emperors." ”
