Due to the release of the new type of refined iron, Li Liangzuo decided to postpone the time of the artillery test firing, first cast a new type of iron cannon, if it can really be cast into an iron cannon, this is tantamount to another good news, the cost of the iron cannon is much lower than the bronze cannon, but also more corrosion-resistant, light weight and easy to transport......

"Go and get the mold for casting cannons, we'll cast cannons here, this furnace of molten iron should be able to cast two iron cannons." Jin Bohang said to his subordinates.

Under the gaze of Li Liangzuo and others, Jin Bohang personally started casting, and there are very high requirements for the casting of artillery, under such primitive conditions, the success or failure of an artillery is mainly determined by two details, the first is the mold of the artillery, and the second is the casting of the artillery; The molten iron must be in the best condition when casting, and it must be poured all at once, otherwise the gun will be wasted.

For casting artillery, Jin Bohang has been very proficient, so many years of firearms research and technology agency cast no less than thousands of artillery, although the vast majority of these artillery are failures, but Jin Bohang and others have figured out the way to cast the artillery successfully; Casting was only 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, and the next step is to wait for the cooling to see if there is any gap, and then polish it...... Finally, in the installation of the mountain, the door; It will also take a lot of test firing 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 make in a month?" ”

"If the supply of refined iron is sufficient, there should be no problem in making ten doors a month."

"Okay, the iron cannon will be tested first, and after these two cannons are cooled, they will be completed quickly, and I will wait here for a test shot with the bronze cannon." Li Liangzuo said.

"Your Majesty, I'm afraid it will take more than ten days." Jin Bohang said to Li Liangzuo.

"It's okay, I can wait, just use the next few days to take a good look at this Firearms Research and Technology Agency......"

During the production of the two iron guns, Li Liangzuo visited the manufacturing plant of the fire gun, the manufacture of the fire gun has become an assembly line operation, in order to solve the problem that the fire gun is easy to explode, although the fire gun is still made of iron, but the way of building has been completely changed, the current fire gun is composed of two layers of iron sheets, the first step is to roll the first layer of iron sheet into an iron pipe, the gap is cast and polished, the second step is to roll a layer of iron sheet on the periphery of this layer of iron sheet, and then use molten iron to cast the gap between the two layers of iron sheet, Finally, the inside and outside of the iron pipe are finally polished......

The iron pipe is the most critical part of the firecracker, after the iron pipe is made, the rest is easy to say, this way of making is much faster than the way of drilling, watching the iron pipe being rolled up, Li Liangzuo asked Jin Bohang: "What is the production capacity of this firecracker?" ”

"Your Majesty can now make twenty to thirty firecrackers a day, and about a thousand a month." Jin Bohang said to Li Liangzuo.

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

"Your Majesty, it is roughly estimated that there will not be twenty silver coins, which is not enough if it is mass-produced, and this price can continue to be reduced." Jin Bohang said to Li Liangzuo.

"Don't rush into mass production just yet, after digging out the best performance of the firecracker, it's not too late to produce 5,000 rods, and ......"

"Yes, Your Majesty Weichen remembered ......"

"By the way, what is the range of this firebolt?" Li Liangzuo continued to ask.

"Between 100 and 110 steps, the effective range is only 70 or 80 steps, and we use lead bullets, and if we get farther away, we start to float......" Jin Bohang said to Li Liangzuo.

Li Liangzuo also knew what Jin Bohang said, and after thinking about it, Li Liangzuo said: "Go and bring me paper and pen." ”

After the paper and pen were brought, Li Liangzuo asked Jin Bohang again: "The caliber of these firearms you made are all the same!" ”

"Your Majesty, what is this caliber?"

"The caliber is the inside of this iron pipe you made, how can you say it! It's just that this place is not the same. Li Liangzuo took an iron pipe as he spoke.

"They all use the same mold, of course the same caliber." Kim Bohang said.

Then Li Liangzuo drew a cone-shaped mini bullet on the paper, and Li Liangzuo handed the painting to Jin Bohang and said: "You take this drawing, make all the lead bullets like this, the middle position is empty, and the size should be just enough to fit into the chamber of the gun." ”

"Breech?" Jin Bohang was confused.

"It's the ...... of the firebolt pipe"

"Weichen understands, Your Majesty, why are you honestly inventing some new words!"

"Let's do it! Do as much as you can. ”

Under the command of Li Liangzuo, Jin Bohang has carried out a transformation of the firecracker, the newly transformed firearm was Li Liangzuo became a bird gun (arquebus), although it is still a front-end charge smoothbore gun, but this is already a great progress, and finally this kind of bird gun was finalized and mass-produced, as for the previously made firearms all used as test products, the appearance of the bird gun will make Xia Jun officially enter the era of firearms and cold weapons alternately.

Ten days later, the two iron cannons have been manufactured, and the bird guns have also made one hundred and fifty rods, because the production of the bird guns is more complicated than the original firecrackers, and the craftsmen are not skilled enough, so the output is not high, and it is quite good to be able to make one hundred and fifty guns, after these are all prepared, the final test firing of firearms is about to begin, in order to test the power of the artillery, Li Liangzuo specially ordered the construction of a specially reinforced city wall according to the standards of the Xia army's city defense.

"Your Majesty, this is a city wall built according to your request, used to test artillery, and the target over there is used to test a new type of bird gun." Jin Bohang reported to Li Liangzuo.

"Let's test fire the artillery first! Load a solid bullet and let me see how powerful it is? Li Liangzuo ordered.

"Your Majesty, this solid bullet has made four kinds of Weichen, one is a spherical solid iron bullet, the second is a scattered bullet, the third is a flowering bullet, and the last is a new type of live ammunition made of a conical bullet (Mini bullet) to prevent the bird gun."

"Okay! Learn to draw inferences so quickly; Let's test shoot! Use solid bullets first. ”

"Yes, Your Majesty has ordered the test firing to begin, and the first round is loaded with solid ......"

"Ignition ......"

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

After a burst of artillery smoke dissipated, craters were left on the city wall in the distance, and the huge power of the artillery shocked Li Xiaoren and others, but Li Liangzuo's face was very calm; Then there were shots, flowering bullets and conical bullets, and their power was also considerable.

After the artillery test firing was completed, the test firing of the bird gun began, and the test firing directly used a new type of conical projectile, and the target was replaced by a group of goats, and at the request of Li Liangzuo, a three-stage attack was adopted, and every 50 people were a team, and the fire was carried out repeatedly, starting from 200 paces, from far to near; The new bird gun and the conical bullet are enough to cause great damage to the goats at a distance of 200 paces.

The test firing of the new artillery and the bird gun was a complete success, and Li Liangzuo's large investment in firearms over the years was finally not in vain. For Xia Jun, a new way of warfare has begun, and it is at the forefront of the world.

The first update is coming, so let's support it if you have a ticket! Thanks to the book friend 6054 for the four recommendations, and the book friend active for the three recommendations......
