Because the chamber had to be wiped extremely clean and smooth, it took a while for the four hexagonal rifles to be ready.

Luckdhun, who was less than a hundred feet away, had already urged impatiently a few times, and finally saw Bai Zong, who was in charge of commanding the four cannons, raise a small pennant and shout, "Fire!" ”

When the herald heard the news, he hurriedly sounded the gong vigorously, and the gunpowder next to the fire door at the end of the cannon was immediately ignited by four captives. Mars was the first to burrow into the ignition of the first cannon from the left, and it turned into a dull roar.

A hexagonal angular shell cast in the shape of a twist flew out of the muzzle of the gun under the impetus of smoke and fire, and spun axially under the action of the twisted hexagonal barrel.

Immediately, two more cannons followed with a loud bang. Because of their rotational effect, the three shells were very stable in their flight trajectory, whizzing over the battle formations of the Jianyu Central Army and the Front Army, and smashed heavily more than 200 paces in front of the infantry line of the Dragon Guard Army four miles away, stirring up a cloud of earth and gravel.

However, because the shell is not spherical, the ricochet effect is not obvious, and it only jumps forward irregularly for thirty or forty feet before exhausting the kinetic energy.

Luckedhun's scalp was tingling with the fierce sound of the new cannon, and he couldn't help but be ecstatic, and immediately raised his binoculars to observe the effects of the shelling.

But he didn't see anything clearly, but he suddenly heard another earth-shattering "boom" in his ears, like a drought thunderbolt not far away, and the movement was more than ten times greater than the previous three cannons!

Lucker's ears were ringing, and he wondered why the last cannon was so powerful. When he turned his head to look, he was shocked to see that the place a hundred zhang away from the north side was scorched black, and the four hexagonal cannons that were still showing off their might had disappeared without a trace, and there were countless stumps and broken arms scattered around, and a large amount of blood was sprayed in a fan shape to more than thirty zhang away.

After a moment of silence, the rear team of the Qing army suddenly erupted into a scream like killing pigs, "Bomb, blow up!" ”

"It's blown up, run......"

"The cannon has exploded, come and save people!"

"It hurts me, help......"

"Save Me ......"

Even two of the guards closest to the north were dropped from their horses, rolling on the ground with bloody wounds, only to be wounded by flying splinters or stones.

Lucker's face turned pale with anger, but he didn't expect that the "magic weapon" that he had high hopes for didn't even hurt a single hair of the Ming army, but he first "opened his beard" in his own backyard.

Taking the place where the cannon was placed just now as the center of the circle, none of the soldiers within 20 zhang of the surrounding area were spared, and at least three or four hundred people died. Lucker's heart suddenly sank, if he had come closer, he was afraid that his life would not be guaranteed.

"Cai Shiying, this bastard thing!" He gritted his teeth and said, "Lao Tzu will definitely break you into pieces when he goes back!" ”

In fact, this can't all be blamed on Cai Shiying, with the casting level of the seventeenth century, it is impossible to create a working hexagonal rifle cannon. Even in the nineteenth century, Britain after the industrial revolution did not dare to guarantee the absolute reliability of this cannon.

It's just that John Tang blew this new invention into the sky in front of Cai Shiying, and the latter strongly recommended this new cannon to Dolgon, Luckdehun and others, and made a lot of money from the silver of the imperial court's cannon casting.

However, after John Tang started casting, he found that the progress was extremely unsmooth, and a lot of manpower and material resources were consumed, and more than ninety percent of the cannons cast either had cracks or the pipe walls were not symmetrical. You must know that the friction between the shell of this cannon and the inner wall of the barrel is extremely large, as long as there is a little inaccuracy, let alone firing the cannon, and even the cannonball cannot be loaded into the barrel at all.

However, John Tang did not know that the technical level required to cast the hexagonal rifle cannon was far beyond his limit, and he still tried desperately to improve the process like an evil spirit, and mobilized thousands of gunsmiths and more than 4,000 laborers to make a large number of trial productions. It can be said that he was "lucky", because the casting base was too large, and by chance, four cannons that seemed to have no defects were actually built.

Cai Shiying was overjoyed when he heard the news, and he simply let people test a few shots, and when he saw that the real shot was more than four miles away, he was urged by Luckett, so he immediately loaded the car and sent it to Jiangnan.

However, in fact, this cannon was made of stainless steel in later generations, which allowed the barrel to remain stable after multiple fires. And Zhu Linmiao's drawings did not mark the cannon body material, so Tang Ruowang took it for granted that he used the best cannon casting material of the current era - bronze. Bronze has good ductility and can withstand higher chamber pressure, but it is not rigid and easy to deform.

After Cai Shiying's test firing, the barrel has undergone a slight deformation, although it is not visible to the naked eye, but for the hexagonal rotor gun that requires very precision, it is enough to increase the friction between the shell and the gun chamber several times!

Just in time for the first time in front of the battle, one of the cannons could no longer withstand the terrifying pressure of more than 300MPa, and exploded gorgeously.

In fact, even if this cannon is fine, this new cannon of "rough local method" will not be able to withstand the next launch.

Luckettun looked at the Qing soldiers who were in a mess with a gloomy face, fortunately it was in the rear, if it was in front of the formation, the Ming army would take advantage of the chaos to cover up and kill, and the army would be defeated!

He waved to the guards beside him, "Don't let these people mess up!" ”

Immediately, three hundred baralas rushed forward with their knives drawn, pointing their fingers everywhere and shouting, "Get back!" ”

"Don't run around!"

"Deaf?! Put people down and return to the battle immediately! ”

They drove the captives back into the battle and stabbed the wounded on the ground.

Most of the rear troops were Yu Yongshou Wucai and Huizhou Green Battalion soldiers, and when they saw Bayala viciously beheading their wounded robes, they were all full of grief and indignation but dared not speak angrily.

When the team finally regained its "calm", Luckard held his breath and yelled to the herald, "Drumming! The front army directly attacked the Southern Barbarian army formation! He said to himself in a cold voice, "But it's just 30,000 Nikan, what kind of cannon is used?" Kill head-on! ”

"Huh!"

Immediately, the drums of the Qing army were beaten. The Jianyu forward was only two and a half miles away from the Ming army, and Babutai, who was in charge of commanding the front army, heard the news of the saber and pointed forward, and more than a dozen officers beside him immediately galloped back to his own formation.

After another moment, on the frontal battlefield six or seven miles wide, the battle formation of 40,000 Qing troops began to move forward slowly.

The Jurong area is spacious and flat, and when fighting here, any outflanking, sneak attack, detour, and so on will be seen by the other side from afar, and it will hardly play any role except to disperse their own forces. Therefore, Lucketthun came up and attacked head-on, in order to crush the Ming army in one fell swoop with absolute superiority in strength and combat effectiveness.
