Boom!

The Tiger Guards covered their buzzing ears and looked at the powerful cannon at first glance.

Zhao Da Hammer ran in front of Guo Jia.

"Lord, the power of the new cannon is so great, it actually shattered the brick wall three miles away."

Guo Jia nodded with satisfaction.

With the advent of gunpowder, stone-throwing carts and bronze cannons appeared on the land of the Central Plains in advance.

Whether it is a gun carriage or artillery, it can kill and injure the enemy in a large area.

With the advantage of Yunzhou, it is completely possible to hang everything.

At the shipyard in Jizhou, the first deep-sea warship is being built intensively, and an artillery gun is urgently needed to increase its power.

In fact, in the existing artillery system in Yunzhou, heavy stone-throwing vehicles and bronze artillery can also meet the needs of shipborne guns.

It's just that the heavy catapult has a large frame and needs to occupy a lot of space, which is a big disadvantage for sea vessels with limited decks.

The other bronze cannon, although small in size, has a short combat radius and cannot highlight its power.

Therefore, Guo Jia desperately needed a cannon that could be fired on a ship.

Unlike land artillery, naval artillery does not need to scatter, because the scattering distance is short and not powerful, and it is more necessary to fire large projectiles to destroy enemy ships from a long distance.

Guo Jia's first thought was the Frankie smoothbore gun.

In the Age of Discovery, the most commonly used ship was the Franky gun, which was very popular with Europeans with a light body, long range and fast rate of fire.

The Furlong Cannon was an early reloader smoothbore cannon. It is composed of a mother and a child gun. The female body is slender and has a small caliber, and the body is equipped with a front sight and a light door, which can aim and shoot at long-distance targets. There are gun lugs on both sides of the gun body, which can be placed on the bracket and can be tilted to adjust the firing angle. The rear part of the gun is thicker, and there are long holes and grooves to fill the guns. The sub-guns are similar to the small firearms, each female gun is equipped with 5 to 9 sub-guns, which can be pre-loaded with ammunition for backup, and the mother guns can be loaded and fired in turn during battle, thus increasing the firing speed.

The Yunzhou bronze artillery manufactured by Guo Jia also borrowed from this model.

It's just that the current smelting technology is relatively low, and it can't effectively store copper and iron, and the bronze made by Guo Jia contains a lot of impurities, basically after hundreds of rounds, the cannon body will crack.

So it was still difficult to make a good Frankie cannon.

Youzhou suddenly discovered a strange pit, and Thorn Shi Tianfeng transported some to Yunzhou. After Guo Jia's investigation, it was found that it was meteorite, which may have fallen before, and there was a stock of nearly 100 tons.

Over the years, it has weathered and become a large mining pit.

This time, Guo Jiadeng was overjoyed.

Meteorite is a good thing, it contains very few impurities, and it is very suitable for making cannons.

Just do it, after confirming that these black and unsightly stones were meteoric iron, Guo Jia immediately asked people to transport things to Yunzhou.

Get your hands dirty and start smelting meteoric iron.

After years of smelting bronze, Yunzhou's smelting technology has become very mature.

But it was the first time to smelt meteoric iron.

In order to increase the purity of meteorite, Guo Jia deliberately used anthracite and leather bladder hair dryers to increase production capacity.

After three days and three nights of hard work, the first meteorite cannon was finally produced.

The cannon is modeled after Frankie's and uses a rear-loading sub-cannon, which is ignited by flint.

Like the bronze cannon, the meteorite iron cannon is also formed in one piece using the infusion method.

The next step was to polish and assemble, and a dark meteorite cannon appeared in the school yard in Yunzhou.

This cannon weighs more than 800 catties, the whole body is dark, Guo Jia is also a craftsman to build bronze wheels, installed on the iron cannon to sit.

The shells were also very extravagant, and they were forged from rough iron embryos.

Rough iron was also very rare in this era, if it weren't for the discovery of a crater in Youzhou, Guo Jia would not be willing to use these thick iron to make cannonballs.

Everything is ready, Guo Jia can't wait to come to the school field and try the power of the meteoric iron cannon.

In fact, the danger of testing artillery is far greater than that of war, especially when experimenting with new cannons, due to the instability of bronze cannons, there are often accidents that injure people when testing cannons, and many people die as a result.

So testing guns is also a dangerous job.

But this time, the artillery king Zhao Dazhui personally went into battle, adjusted the muzzle of the cannon, replaced it with a gun, and everything was ready.

Bang!

Zhao Da Hammer pulled the rope, and the meteoric iron cannon let out an angry roar, and the cannonball whistled and flew into the distance.

Boom, hit the target.

I have to say that Zhao Dazhui's technique is still very good.

Reload!

Zhao Dazhui shouted, and several soldiers skillfully removed the gun, replaced it with a new gun, and cleaned the barrel.

Bang bang bang!

Zhao Dazhui fired five shots in a row and hit three shots, which is already commendable in this era of no radar and no navigation.

Very good!

Guo Jia nodded with satisfaction.

The smoke clears!

The iron cannon stood proudly on the school grounds, like a general who had won a battle.

Guo Jia stepped forward and stroked the cannon body, and a hot temperature came up.

Iron is harder than copper, the barrel is durable, and the accuracy is higher than that of copper cannons.

The curves are perfect.

It's more durable than the brass cannon, but it's a pity that it's a little clumsy, but it's still okay to put it on a ship.

Lord!

Zhao Dazhui stepped forward with a smile: "If Yunzhou is replaced with this kind of cannon, I dare to guarantee that fifty guns will be able to defeat Xudu City." ”

This thing is a solid bullet, it can smash a brick wall three miles away, and fifty artillery pieces are fired intensively at one time, and there is no problem in destroying a city.

Hehe!

Guo Jia just smiled.

It is already a mistake of God to be able to find meteoric iron, and the amount of meteorite iron found can make more than a hundred meteorite cannons at most, and good steel should be used on the blade, and these cannons can only be used on ships.

At this moment, Dian Wei suddenly came in a hurry.

"The lord is not good!"

He brought bad news.

……

Su Qinglian disappeared, Skynet's foothold in Xudu was razed to the ground, and the news soon spread to Yunzhou.

At the same time, a letter was also sent to Guo Jia, and the merchant invited him to talk to Xudu, otherwise Su Qing's life would not be saved.

Guo Jia didn't say a word, and immediately decided to get up and go to Xudu.

Lord, no!

Xi Zhongxin Ping and others knelt in front of the door.

They must not let Guo Jia leave.

Xu Du is Cao Cao's territory, and if he is not careful, he will encounter danger. If Cao Cao encounters Guo Jia, the great enemy in his life, he will definitely not let it go easily.

Besides, for a woman, it's not worth it.

"He's my woman!"

Guo Jia said word by word.

For his own women, although Guo Jia can't give them an equal name, he must be able to be fair and just.

Cai Yan is in danger, and he can leave everything behind to stay.

Now that Su Qinglian is in danger, he can also go to Xudu.
