Within the Western thieves, some people were dreaming of occupying the entire Shaanxi with the power of the Jin people, and some were dreaming of resuming the Liao Dynasty with the power of the Song Dynasty. However, as an important role in these two dreams, Zhao Kai now doesn't care at all about what the Dangxiang people and the Khitans planned.

Because he has now had eighteen and twenty-five kilograms of "big hot pot", not the pot weighs twenty-five kilograms, but the iron bullets fired by this big hot pot cannon weigh twenty-five kilograms!

The pot of this type of "hot pot" is three feet long, and the diameter is about half a foot - although Zhao Kai repeatedly emphasizes "standardization", the diameter of each "pot" is different after being cast, but it does not affect the use. Because the size of the cast iron shells sent by Zhang Guanghui and Chen Qian, two profiteers, is not exactly the same, and the weight is of course also up and down, and the so-called "twenty-five kilograms" is also an approximate number.

However, although Zhang Guanghui and Chen Qian are very profitable, their brains are quite good. They both cast shells smaller (mainly for saving materials) and will not be stuck in the "pot".

However, there is also a problem with the shells being smaller, which is that too much air leakage will seriously affect the range and accuracy of the hot pot cannon. Fortunately, Zhao Kai, who is familiar with the "Four Great Soldiers Book", also looked for many weapons information from the 18th and 19th centuries on the Internet, so he knew how to overcome the problem of air leakage in the cannon chamber. He asked the carpenter in the palace to use cork to create some wooden holders (the pattern of the wooden holders was painted by Zhao Kai), and then sent these wooden holders to the carpenters in Luoyang City as samples and ordered tens of thousands... Of course, after these wooden holders were made, the caliber was slightly larger than the "pot mouth". Before use, the military carpenters needed to fine-process according to the corresponding "pot mouth" of the hot pot cannon.

There are two other uses of these wooden brackets. One is to tie the wooden bracket and the iron bullet together with a cloth strip, turn the wooden bracket into a tail wing to stabilize the trajectory and improve accuracy. The other method is to place the heated shell directly on the wooden bracket and shoot it out - this is the arson bomb!

As for the flowering bullet... Of course, it has been "invented", but it can't be used!

This is because the trial production of cast iron flowering bullets has not been successful yet, but the coppersmiths in Fucai Supervision cast bronze flowering bullets... One flowering bullet will take 18 kilograms of bronze! Although Zhao Kai’s annual salary is 6 million, he still cannot afford such flowering bullets.

In addition to cast iron bullets, Zhao Kai also ordered people to create a batch of stone bullets... they are stone shells! This one is both cheap and easy to manufacture. Just pick up some suitable stones, polish them, and tie them to a wooden support and you can beat them out!

Outside Xuanwu City (this is a Jiacheng and part of Luoyang Imperial City) on the north side of Ziwei Palace in Luoyang, there is a newly opened imperial shooting range. Zhao Kai is standing on the wall of Xuanwu Gate and watching the eight gun groups on the shooting range outside Xuanwu City, slowly fiddling with eight "big hotpot cannons".

Although the "big hot pot cannons" have been delivered, there are only eight gun groups available, four of which are composed of Zhao Kai's twenty female squads and four craftsmen. The remaining four are personally responsible by Xu Qing, Tang Xian, Wu Lin, Huang Wubing, four generals, deputy generals, and generals. If you want to be an artillery officer, you can't play artillery!

As for the standard method of playing cannons, it was also summarized by Zhao Kai based on his memories of his previous life and the female squads for more than a month.

There were six people in one gun team, one gun captain, two were responsible for loading ammunition, two were responsible for clearing the chamber, and one was a craftsman who was responsible for repairing artillery, modifying wooden brackets, knocking stone bullets, and heating shells - if arson bullets were to be fired.

If you really go to the battlefield, you may have to be equipped with a group of strong men responsible for carrying artillery shells! After all, they are twenty-five kilograms of artillery shells. If you really have to carry them for a few hours, the iron man will have to be exhausted!

When loading ammunition, you must first load the medicine bag, then press it with a push rod, then put cork (cork can also be tied together with shells), then set the shells, and finally press it again.

The gunner is responsible for aiming and ignition. The aiming method is to adjust the firing angle. The "hot pot cannon" has gun ears on both sides and can be placed into the bayonet of the "wooden box" gun mount, so you can raise the muzzle and then add or adjust the mat to change the firing angle. When changing the firing angle, five gunners are required to work together.

Ignition is to use a fuse and an ignition rod - the fuse is a rope soaked in the silt water. After the gunman pierces the medicine bag with a long needle, it is inserted into it. Then, an ignition rod wrapped around the ignition long fuse to ignite the fuse. After igniting the fuse, all the members of the gun crew must retreat to the cover built with sandbags to avoid exploding the chamber...

After the shot, two gunners were responsible for cleaning the chamber, using the cleaning rod equipped with an inverted hook to remove all the fragments in the chamber, and then using another cleaning rod equipped with felt to dip the chamber into water.

After more than a month of high-intensity training, all seven gun teams are already more skilled. However, the rate of fire is still not high, and it takes three or four minutes to fire a shell. If they go to the battlefield, it is enough for them to maintain this rate of fire.

It can almost shoot 40 rounds in one hour, and there are 200 rounds in five hours a day. If 8 guns are fully fired, it will be 1,600 rounds a day, and 4,800 rounds in three days... How can Lingzhou City withstand it? That is a 25-pound iron bomb and stone bomb, and some of them are arson bombs!

If you can really withstand it, it doesn't matter... Zhao Kai has also prepared to dig a sub-army, and he can make holes while firing cannons. As long as he can dig under the Lingzhou city wall and put more than a dozen barrels of black gunpowder, what kind of city wall can't collapse?

"Boom boom boom..."

Just as Zhao Kai was thinking about how to take down Lingzhou City with lightning speed, the eight 25-pound "big hotpot cannon" placed in the shooting range had already started!

This movement was much louder than the 10-pound "pot" that was fired on the Fucai Supervision shooting range before. Even standing on the city wall from afar, there was a deafening feeling. It scared Zhao Kai to a young girl dressed in a man next to him screamed and rushed straight into his arms.

"Xiaomei, don't be afraid, I'm here!" Zhao Kai hurriedly comforted the little girl - the little girl is timid! Although Zhao Kai was not around, she also fiddled with cannons and gunpowder with a group of female squads. According to Guo Tiannu, she was the best one among them. But whenever Zhao Kai was by her side, she became cute.

"Ahem..."

Someone suddenly coughed violently beside Zhao Kai. He quickly turned around and found that it was Han Shizhong... I don’t know if it was choking on the smell of gunpowder floating up from below?

Zhao Kai then found that there were big men standing around him, all staring at him hugging the little girl!

Ah, today I took my ministers to see the "hot pot" test firing!

He quickly let go of Wu Meiniang, and restored his solemn appearance as a king, and then turned his eyes to the target on the shooting range outside Xuanwu City - a circle of temporarily rammed earth walls.

The rammed earth wall is not high, but it has enclosed a large piece of land - the accuracy of the "big hot pot cannon" is very low, so it can only be used to set large fixed targets (such as a castle) at close range (such as a few hundred meters).

All eight projectiles fell into the earthen wall... They hit it very accurately - of course they were accurate! This is not the first time they hit this target these days, and they have already found the right feeling. The shooting angle and distance are fixed, and they can hit it even with their eyes closed.

However, Lingzhou City is larger than that circle of earth walls, so it is impossible to not be able to hit. The question is whether the shells can be bombarded on the top of Lingzhou City Walls?

"Good fight!" Zhao Kai nodded with a smile and said to the ministers around him, "With these eighteen big hotpot cannons, not only will the Golden Thieves be finished, but the Western Thieves are not much better!"

There were civil officials and military generals present, and many of them saw the "big hotpot cannon" fire for the first time. Although everyone heard the loud noise of the "big hotpot cannon" fire, the area outside the Xuanwu Gate was surrounded by the Tiance army, and idle people were not allowed to approach.

So everyone only knows that the official family goes to outside Xuanwu Gate to "thunder" every day. As for how this "thunder method" was shot out, everyone doesn't know... Some people think that the official family has cultivated magical powers and can use thunder to hit targets on the ground!

Unexpectedly, this thunder method turned out to be a "big hot pot cannon"!

"The official's thunder magic has great powers. Just the Western thieves and Jin thieves can only be awarded the title sooner or later!"

"The official pot is amazing. It will definitely be able to make the Western thieves and the Jin thieves in one pot!"

"The official's pot can be used to take over the world! I will congratulate you on the official!"

"The official family has such a magical weapon. This Northern Expedition to Yanyun will definitely win a great victory..."

The ministers had already reacted and all praised the best. Several of them did not understand the thunder method and the pot method, and they also blew it hard.

Anyway, flattery is never bad!

Zhao Kai was also very proud and said to these ministers: "I want to travel to Chang'an in the west and inspect various parts of Guanzhong... It's not too long, I will return in three or two months. No one has to follow me, just be protected by Yue Fei, Dong Jingang and Li Fuchen. In the Eastern Capital, I will trouble you, the Privy Councilor, and the Privy Councilor assisted the Queen in supervising the country!

The Guangwu Mountain Camp is still left by Han Liangchen, and the Hebei Guzhen Camp is guarded by Huang Silang... Everyone is dedicated to their duties and must not be slackened at all.

In addition, Mr. Zhao, this time, the cannon casting is a great contribution! You will get me the list of craftsmen involved in cannon casting. I will summon them and award them a medal and reward!"

Zhao Kai had to be lucky this time, of course, to Lingzhou all the way, but he could not tell this matter publicly, as it would be bad if the news leaked.

So he said he went to Shaanxi for inspection, but the important officials present knew it - today Zhao Kai took them to see the cannon test firing, and the purpose was to calm their hearts!

This official has such powerful "magic powers", and it is no problem to just thieves! So if you want to persuade the people who are polite in this official family, you should not speak and wait and listen to the good news!
