Due to the release of the new fine iron, Li Liangzuo decided to postpone the test firing of the artillery and cast a new iron cannon first. If it can be cast into an iron cannon, this is another good news. The cost of the iron cannon is much lower than that of the bronze cannon, and it is more corrosion-resistant, light in weight and convenient for transportation...

"Go and bring the mold of the cast gun. We will cast the gun here. This furnace of molten iron should be able to cast two iron cannons." Kimberhang said to his men.

Under the gaze of Li Liangzuo and others, Jin Bohang personally started casting, which had high requirements for casting the cannon. Under such primitive conditions, the success or failure of a cannon mainly depends on two details. The first is the mold of the cannon, and the second is the casting of the cannon; the molten iron must be in the best state during casting, and it must be cast at one time, otherwise the cannon will be scrapped.

Kimberhang is already very skilled in casting artillery. Over the years, the Firearms Research and Technology Bureau has cast no less than a thousand artillery pieces. Although most of these artillery are failed, Kimberhang and others have figured out how to successfully cast artillery; casting is just the first step in casting artillery.

After the casting was completed, Jin Bohang said to Li Liangzuo: "Your Majesty, this first step has been completed. The next step is to wait until it cools down to see if there is a gap, and then polish it... Finally, install the Wangshan Mountain and take a look at the door; and a large number of test shots are required to ensure the quality of the artillery..."

Li Liangzuo nodded and said, "If this kind of fine iron can be reached, how many cannons can you build in a month?"

"If the fine iron supply is enough, it should be no problem to build ten doors a month."

"Okay, the iron cannon will be tested first. After these two cannons have cooled down, they will be completed quickly. I will wait here to test the fire with the bronze cannon." Li Liangzuo said.

"Your Majesty, it may take more than ten days." Jin Bohang said to Li Liangzuo.

"It doesn't matter. I can wait. I just took advantage of these days to take a good look at the Firearms Research and Technology Department..."

During the production of two iron cannons, Li Liangzuo visited the manufacturing plant of the musket. The manufacturing of muskets has become an assembly line operation. In order to solve the problem that muskets are prone to blowing the chamber, although the muskets are still made of iron, the construction method has been completely changed. The muskets are now composed of two layers of iron sheets. The first step is to roll the first layer of iron sheet into an iron pipe and cast and polish the gaps. The second step is to roll a layer of iron sheet on the periphery of this layer of iron sheet, and then cast the gaps between the two layers of iron sheets with iron, and finally the inside and outside of the iron pipe are finally polished...

Iron pipes are the most critical part of the musket. After making iron pipes, everything else is easy to say. This way of making is much faster than drilling. Seeing the iron pipes being rolled up, Li Liangzuo asked Jin Bohang: "What is the production capacity of this musket?"

"Reported to your Majesty, now he can make twenty to thirty muskets a day, and he can produce about a thousand guns a month." Jin Bohang said to Li Liangzuo.

"How much does this musket cost?" Li Liangzuo continued to ask.

"Report to Your Majesty, I guess I won't pay twenty silver coins, which is not enough if it is mass-produced, the price can continue to be reduced." Jin Bohang said to Li Liangzuo.

"Don't rush to mass production on a large scale first. After excavating the best performance of the musket, it will be no longer late to produce on a large scale. Just produce 5,000 rods first..."

"Yes, Your Majesty remembers..."

"By the way, how is the range of this kind of musket?" Li Liangzuo continued to ask.

"Whether between one hundred and one hundred and ten steps, the effective range is only seventy or eighty steps. We use lead bullets, and when we go further, we will start to float..." Jin Bohang said to Li Liangzuo.

Li Liangzuo also knew what Kimberly Hang said. After thinking about it, Li Liangzuo said, "Go and bring me paper and pen."

After taking the paper and pen, Li Liangzuo asked Jin Bohang again: "The calibers you made are the same!"

"Your Majesty, what is this caliber?"

"The diameter is inside the iron pipe you made. How can I say it? Is this place the same?" Li Liangzuo took a iron pipe as he said.

"They use the same mold, of course the same diameter." Kimberhang said.

Then Li Liangzuo drew a cone-shaped Minnie bullet on the paper. Li Liangzuo handed the drawing to Kimberhang and said, "You take this drawing and make all the lead bullets look like this. The middle position is empty, and the size should be just right in the gun chamber."

"The gun chamber?" Kimberhang was stunned.

"It's the musket barrel..."

"I understand, Your Majesty, why are you honestly inventing new words?"

"Do it quickly! Do as much as you can."

Under the command of Li Liangzuo, Jin Bohang transformed the muskets. The newly renovated muskets were made into bird guns (melting rope guns) by Li Liangzuo. Although they were still smoothbore guns loaded at the front end, this was a great progress. In the end, this bird gun was finalized and mass-produced. As for the muskets made before, all of them were used as test items, the emergence of bird guns will allow the Xia army to officially enter the era of alternating firearms and cold weapons.

Ten days later, two iron cannons had been manufactured, and one hundred and fifty bird cannons were made. Since the production of bird cannons was more complicated than the original fire cannons, and the craftsmen were not skilled enough, it was quite good to make one hundred and fifty cannons. After all these were prepared, the final test of the firearm was about to be launched. In order to test the power of the cannons, Li Liangzuo specially ordered a specially reinforced city wall to be built according to the standards of Xia army city defense.

"Your Majesty, this is a city wall built according to your requirements to test artillery, and the targets there are used to test new bird guns." Jin Bohang reported to Li Liangzuohui.

"Try the cannon first! Install the solid bullet and let me see how powerful it is?" Li Liangzuo ordered.

"Your Majesty, I have made four types of solid bullets, one is a spherical solid iron bullet, the second is a shotgun, the third is a flowering bullet, and the last is a new type of live bullet made of the cone bullet (Mini bullet) of the anti-shock gun."

"Okay! You'll learn to learn from one example so quickly; test the shot! Use a solid bullet first."

"Yes, Your Majesty has ordered the test firing to begin, the first loading of solid bullets..."

"ignition……"

"Boom, boom, boom, boom..."

After a burst of gunfire dissipated, there were craters left on the city walls in the distance. The huge power of the cannon shocked Li Xiaoren and others, but Li Liangzuo's face was very calm; then there were shot shots, flowering bullets and cone bullets, which were also quite impressive.

After the cannon test was completed, the test shot of the bird gun was started. The test shot was directly used to use a new cone bullet, and the target was replaced with a group of goats. At the request of Li Liangzuo, three-stage strikes were adopted, and each fifty people were in a team, and the distance was 200 steps, from far to near. The new bird gun plus the cone bullet, the distance of two hundred steps was enough to cause great lethality to the goats.

The test shooting of new cannons and bird guns was successfully withdrawn. Over the years, Li Liangzuo's large-scale investment in firearms was finally in vain. For the Xia army, a new way of war has been opened, and he is at the forefront of the world.
