After the iron mold cooled slowly, Wayne took a ruler to measure, and from time to time measured the size of the mold mouth, how long the mold body was, and so on.

Wayne was also glad that rulers and some basic ground measuring tools had appeared in this era, as well as compasses. There is no need to make another set, otherwise the progress of artillery research and development will fall behind again.

After the iron mold, the cannon will be cast, and it will be prepared in four or five days.

Wayne chose a 12-pounder, 75-caliber naval gun, after all, if you defend the city, you can sacrifice your mobility, to be honest, it is a bit reluctant to defend the city with such a small cannon by the standards of the previous life. However, he is not the main battlefield, the real battlefield is the Marquis of Barnfinger, and his Black Flag City is the main direction of attack. Once it was breached, Stuyard could drive all the way to Feken, the capital of Barnfinger's domain. Therefore, the black chess city was carefully built by Barn Finger, known as the iron bucket that will never be breached. Wayne is just a piece of fat in Stuyard's eyes, just send a branch army over.

Moreover, with Wayne's current financial resources, this 12-pounder cannon is estimated to be able to make 8 in a month. Not to mention gunpowder and ammunition. It's better to thank Evans for all these years of hard work, otherwise Wayne would have no money to squander now. And this is not just about money, it is not possible to use materials as you like.

Wayne was now carefully applying a mixture of fine rice husk ash and fine sand mud with water, which was to be evenly applied without any ambiguity. If it is not evenly spread, it will have a great impact on the quality of the artillery, and even directly affect the failure of the cast artillery. The worst-case scenario is to break the mold. Therefore, this kind of delicate thing Wayne himself did to rest assured, and the rough behavior of the craftsman when making black powder made him feel uneasy.

After the first layer is painted, fine coal ash is also applied as a second layer.

"Without these coatings, the molten iron will stick to the mold when poured. That's null and void. ”

Wayne explained carefully, not daring to be a little sloppy, after all, it will be up to this group of people to cast artillery in the future. After applying the coating, Wayne directed the craftsmen to pour it.

As he watched the molten iron slowly fill the mold, Wayne also breathed a sigh of relief. All that's left is cooling, and the craftsman has to knock on the mold. This is to allow the impurities in the molten iron to settle to the bottom.

Wayne took advantage of the time to give Reynolds a lesson.

"Reynolds, you know why you don't use the Clay Forge Cannon. To give you a hint that there is water in the dirt. ”

Reynolds rolled his eyes twice and shook his head blankly.

Wayne said patiently, "I'll give you another hint, I said yesterday that water will turn into water vapor when it encounters high temperatures. Think again. ”

Reynolds looked at the slowly solidifying molten iron, his brow furrowed. Then he happily said to Wayne, "I know, there is water in the soil and hot molten iron." It will turn into water vapor and enter the molten iron, and after the molten iron solidifies, it will form bubbles in the iron wall. ”

Wayne smiled at Reynolds and said, "By the way, you'll see what this cannon can be used for later." You'll understand better why there can't be bubbles in this cannon. ”

This aroused the curiosity of the sixteen-year-old young man, and he looked forward to the usefulness of the artillery even more.

After the molten iron is completely formed, remove the iron mold. Vader looked at the blackened cannon and fumbled excitedly. After the successful test launch tomorrow, a new era will be opened by itself. The bow and arrow that the elves were proud of were scrap under the artillery, after all, he had never heard that the bow and arrow could shoot three kilometers away.

Wayne hurriedly asked Hinderson Butler to come over and transport this to the outskirts. Ask Evans to come over tomorrow, and he'll be eager to scrape the skin of Nolan City to forge a cannon for himself.

The early morning mist had not yet lifted, and Wayne thought it was full of people.

The sunlight shone on the gun, and the reflected light made Evans feel a little dazzling. Evans is still a little skeptical that this so-called cannon is as magical as Wayne said, although the muzzle of the black hole is a little scary, but such an iron lump can be as magical as Wayne said, Evans is a little skeptical.

Wayne shouted to the crowd, "Please plug your ears later, be sure to plug your ears." ”

With that, Wayne took a group of craftsmen to load the cannonballs, and waited for Wayne to finish loading. Hurry back and give the point when you get the order. And don't forget to remind, "Be sure to plug your ears." ”

Evans felt that this was decent, but it was not good to disobey. Plugging his ears carelessly.

But the next moment, he regretted it. He wanted to plug his ears, the sound was too loud.

Rumble~

Then where the muzzle of the gun was pointed, more than ten meters of dirt was splashed, and a large crater was blown out.

Some panicked and fell to the ground. Keep shouting.

"It's magic, it's got to be magic. ”

Evans was momentarily stunned, then reacted to what the cannon had done. Evans reacted immediately, and at this time, the weapon that could guard Nolan City was an incomparably powerful weapon.

Evans happily hugged Wayne and shouted happily, "We are saved, saved." ”

The housekeeper Hinderson also looked at Wayne with a smile on his face, why is his young master so powerful.

After the madness passed, Wayne spoke, "Guys, we have opened a new era, and in this era, Nolan will deploy anyone. This is the result of everyone's hard work, and I would like to give each participating artisan ten gold coins each. ”

When this group of craftsmen heard this, they shouted happily, "Long live Young Master Wayne, long live Young Master Wayne." "Ten gold coins is equivalent to the money they have earned in a whole year.

Evans secretly scraped together the money at this time, "You have to equip Nolan City with this first, after all, this was minted with the help of our Nolan." ”

Wayne, of course, didn't let the old fox go. "But we're out of iron, and we're out of brimstone, and we're out of charcoal..."

Evans quickly interrupted Wayne, "Stop, stop, it's not easy. Nolan lacks everything, but not money. As long as you can provide Nolan with this, the problems that can be solved with money are not a problem. ”

Wayne smiled treacherously, "Then I'm welcome." ”

Evanston felt bad and wanted to regret it. But when he saw the cannon with its mouth still white-eyed, he decided that he couldn't go back. He wanted the city of Nolan to be full of this kind of artillery.

Wayne walked up to Hinderson and patted him on the shoulder. "In the future, I will expand the scale of production, and in the future, it will not be one or two workshops, but a dozen, a large area. Do you have the confidence to handle it well. ”

Hinderson is now almost sixty years old, and since he was eighteen years old, he has followed the Earl of Nils to kill the enemy, and he no longer has the excitement he has now.

With a red face, he shouted at the top of his voice, "Master Wayne, I will definitely do it." ”

Wayne was now overjoyed, casting the cannon in less than a month was completed, which gave him a lot of confidence in his plans for the rest of the day. He didn't think that artillery alone would allow the fragile city of Nolan to resist Stuard's army.

The crowd dragged the artillery and happily returned to Nolan City. However, in order to hide people's eyes, the artillery was covered with a cloth. After all, the sooner this secret weapon is known, the better.
