After the pig iron is smelted into mature iron. The second step is board making. The refined wrought iron is beaten into iron blocks, and then the iron plates are divided into 8 pieces, and then the small iron plates are beaten into tiles, each iron tile is 1 foot 4 inches long, 1 foot 1 inch wide, thick in the middle, and thin on the edges.

This is followed by the reel. 4 pieces of iron tiles are rolled into an iron cylinder with a tire rod, and 8 pieces of iron tiles are rolled into two iron cylinders.

The next step is engagement. Cut the ends of the two iron cylinders neatly, and use several iron nails to join the two iron cylinders into one. Thicken the belly, charge, and firing place of the gun body. Divide 30 catties of iron into two pieces, beat them into iron tiles, and surround them around the belly of the cannon and the places where the charge and fire are fired, and thicken these places to make them strong.

After making the rough billet of the cannon, it is hoisted and put on the shelf. After being put on the shelf, it should be hung with an ink line, and there can be no deviation. The inside of the chamber is milled with a steel drill to be smooth and round, and even the ash in the chamber must be cleaned up with medicinal solution.

Finally, the fire door is installed, and the light door and guard door are filed on the gun body.

A small Franc cannon was thus built.

"Not bad, really good! Catch the horses quickly, and your handiwork is no less than that of the skilled professional blacksmiths! ”。 After polishing, the Franc cannon was shining all over its body, and after a simple test firing, the effective firing range reached almost two miles.

"Big / country is big / country, I didn't expect that in this small fishing village, there is also a hidden dragon and a crouching tiger, and there are talents like horse catching fast!". Antonio also admired Ma Qiang a little.

Although he is also a young man, and he himself comes from an aristocratic family, he can't help but be unconvinced, if it is up to him, I am afraid that it will be difficult to reach such a level.

"It's amazing to have such a high level of quality on the first contact!". Andre was completely relieved and handed over the task of forging the cannon body to Ma Qiang.

However, with the change of the artillery model, the gun body gradually increased and lengthened, Ma Qiang was a little unbearable, more and more materials were consumed, and the manufacturing process requirements were getting higher and higher.

"Young Master, I can't do it anymore, now the body of this artillery is several times the original, and there are more and more places that need to be glued, I can't cope with it!" Ma Qiang said to Li Ling with great difficulty, he was a little embarrassed.

The eldest young master trusted him so much and asked him to be in charge of matters related to the casting of cannons, but Ma Qiang was not able to do what Andre explained, and he was a little embarrassed.

"It's not your fault, there are too many pieces of iron to be glued, and the difficulty is gradually increasing, you naturally can't do it alone, wait for me to talk to Xiaoba, let him send a few smart and clever soldiers to give you an apprenticeship, I think it can reduce your burden!" Li Ling began to comfort Ma Qiang.

He turned to Andre and asked, "Can you think of a way that is not very cumbersome, such as a way to build the entire cannon body at once?" This saves you a lot of trouble. ”

Li Ling remembered that the cannon body made in later generations seemed to use seamless steel tubes, and the entire gun body was integrated, which was not only easy to assemble, but also could reduce the internal friction with the cannonball and increase the range of the cannon.

"This is impossible, I swear to you as a baron, there is absolutely no such technology, not to mention our Franc machine, even if we search the whole world, there is no such technology." Old Andre suddenly lost his temper.

Li Ling is a layman, why is he pointing fingers here? If there is such a technology, his ancestors/country will have already relied on it to conquer the world.

"Young Master, I've heard the elders say that there seems to be a casting method that can meet the requirements you said." Ma Qiang was talking, and when he found Andre looking at him with a frosty face, he was a little hesitant!

"Nonsense. This is absolutely impossible, Li Jieyuan, I advise you to honestly go to Ningbo City to find more skilled craftsmen, don't focus on improving technology, this is definitely not something that can be done in a short time! ”。 Andre left the blacksmith shop in a huff, his heart was extremely uneasy, he had studied for many years and had not found this method of integrating the cannon god body into one, if Li Ling could solve the problem in a short time, he could give the other party a lifetime of work.

"Hey, hey". Li Ling sneered, Andre is too arrogant. Although such a person can achieve something in science and technology, he will definitely not be able to reach the top.

"Ma Qiang, you say slowly, is there a way to do it?"

"Young Master, I heard that the ancestors used the casting method when making the giant cannon, instead of using the forging method as Andre said, but I don't know the specific process!"

Ma Qiang told all the things he knew while reminiscing, the eldest young master is well-informed, maybe he can find some clues!

"Forging, casting.". Li Ling walked back and forth in the room for a few steps, muttering these words repeatedly, always feeling a sense of familiarity, but he couldn't grasp the key to it.

"Casting, modeling!". With a flash of light in front of him, Li Ling finally grasped a clue, as long as he found a suitable model, he could solve this problem.

But where does he go to find the right mold? “。

One person is short, two are long, Li Ling decided to tell Ma Qiang his decision. "Models? What's that? “。 Ma Qiang was confused, and he didn't understand what Li Jieyuan said at all.

You have to rely on yourself at a critical time!

Li Ling walked out of the blacksmith shop with his head down, he had been thinking about how to make a uniform cannon god.

Ma Qiang wiped his sweat, picked up the sledgehammer and began to hit the iron on the case, as long as the skills are proficient, he can meet Andre's requirements, so that he can help Li Jieyuan.

His life was saved by Li Ling, and he must know how to repay his kindness.

At first, Andre thought that Ma Qiang, this kid, would come up with some clever way to solve the problem, but who knew that he was simply practicing his craft according to the old way.

He shook his head a little disappointed, Li Ling was not an immortal, where could he think of a way?

Ships of more than four masts descended down the sea to the port.

Dozens of large boats are moored next to the fishing village, and the scene is extremely spectacular.

"This is the merchant ship of Lu Bancheng? It's huge! ”。

"It's really magnificent, I'll go up there and see it sometime!".

It was rare that some new people came, and the villagers began to talk happily. This port is really getting more and more lively, and their village is alive again!

This time, the Lu family brought a lot of silk and porcelain to Dongying to sell.

Li Ling suddenly realized, and he quickly ran towards the blacksmith shop where Ma Qiang was.

Lu Yun also stayed in the fishing village, seemingly waiting for other partners.

Two days later, he hurried to Andrew's quarters.
