With the strong assistance of Taishou Li An, a large number of craftsmen built day and night, and the basic outline has come out, because of the construction experience of the Xiao family's iron workshop, the progress of the project is very fast, the wall has not been built, the roof has not been covered, several stoves have begun to operate, and a group of blacksmiths are banging loudly.

According to Xiao Yao's plan, the ironshop recruits craftsmen for the masses, after all, if you can learn a craft, a large number of young people will soon join the ironshop, and those with good qualifications will stay, and those who are in good health will be selected to go to the guards as soldiers, anyway, there is food and money to take, and they are willing to do anything!

And Li An and Zu Yuan joined forces, using administrative power and money power, to bring the well-known blacksmiths in the entire counties of Jiangzhou under the door of the iron workshop, with sufficient manpower and rich materials, plus Zhou Chao, the technical director, in a month, the central furnace of the iron workshop has been operational, and the temperature can reach 1500 degrees!

"Young master, the materials for firing the glazed treasures have been prepared, and they can be fired as soon as the temperature of the furnace arrives! And the glazed ware called the Golden Dragon Wine Pot designed by the young master is not complicated, just have me on the line! Zhou Chao pointed to the stones that had been ground into fine powder and said to Xiao Yao, who was a little thoughtful.

The glass process is actually relatively simple, the key is the temperature, it must be above 1500 degrees to burn these powders into glass solutions, in order to blow into various shapes!

"We have fired the glazed treasures so many times in Jiangling, of course there is no problem, but seeing that this central furnace can now burn such a high temperature, I wonder if we should continue our plan in the Xiao Family Iron Workshop and start making muskets and artillery!"

When Xiao Yao was still in the Xiao Family Iron Workshop in Jiangling, with the assistance of Zhou Chao and a group of technical craftsmen, he improved the crucible steelmaking method, refined high-strength iron, and successfully built a barrel that could withstand high chamber pressure.

"Well, I don't think it's a problem, some of these craftsmen recruited by Zu Yuan are highly skilled old blacksmiths, and with their assistance, they should be able to refine high-strength iron!" Zhou Chao also felt that he should make these powerful firearms designed by the young master as soon as possible, but in the Xiao family back then, he didn't make these weapons in time, and he was caught off guard by Yu Wenzhi of Zhou State, and he had no power to fight back at all!

"Good! Then without further ado, let's start building musket artillery right away! Just now to burn this glass treasure, by the way, burn some concave and convex lenses, make some magnifying glasses, telescopes and other tools, be prepared! Xiao Yao decided.

After the glass treasures were secretly fired, Xiao Yao divided these experienced and skilled blacksmiths into two groups, one group was led by Zhou Chao, who was responsible for refining and forging high-strength iron pieces! One group was personally led by Xiao Yao, who was responsible for polishing all kinds of tools and parts: calipers, gears, compasses, drill bits and so on

Xiao Yao decided to make a flint rifle, and he needed to pull out the rifling inside the barrel! Only with rifling can the bullet hit the target more accurately, and the power is greater, and the soldier with the gun can fight more than one enemy!

When Xiao Yao assembled all kinds of parts into a simple primitive lathe, the old blacksmiths who complained that Xiao Yao was tyrannical and made such a good iron into these strange-shaped parts were stunned!

What an ingenious design, shaking the gear, the drill bit can carve a spiral rifling into a hard iron pipe! This Xiao Gongzi is really Lu Ban alive, and he will not dare to underestimate this young boy in the future!

The craftsmen, who were completely convinced, worked even harder, carefully polishing all kinds of musket parts with the help of magnifying glasses: springs, screws, triggers, etc.

Finally, after hammering the drilled barrel, hand-pulling the rifling on the lathe, and then assembling it on a wooden butt, attaching the trigger, flint and steel, etc., a flint gun is complete!

The flint musket designed by Xiao Yao is actually a Mini rifle: a bullet cast with lead, because the diameter is thinner than the barrel, so it can be easily stuffed into the barrel, and the bottom of the bullet is embedded with cork, when shooting, the gunpowder gas impacts the cork, and the cork is suddenly propped up after the instantaneous impact, forming a barrel seal, so that the musket is more powerful and has a longer range!

Within 50 meters, it can shoot through the shield and the human target behind it; Within 100 meters, it can easily shoot through wooden targets covered in iron armor; You can still shoot through cavalry leather armor within 200 meters! Within 400 meters, you can also hit the target accurately! There is still lethality within 700 meters!

When Gao Yuan got this cross-era Mini rifle, he really couldn't put it down, the flint pistol that Xiao Yao gave him belonged to the first generation of products, although it was easy to carry, but the range was only 20 meters, and now this rifle, Gao Yuan, who has been trained in shooting, can shoot down the crow's nest in the tree 100 meters away, has the potential of a sniper, if you install a scope, you can definitely kill people without a trace!

And in addition to Zhou Chao building the barrel, Xiao Yao also asked him to try to build the barrel! Making a cannon is actually easier than making a musket, as long as the barrel can withstand the pressure of the gunpowder explosion.

Xiao Yao designed three kinds of artillery, the first is the projectile cannon, the prototype of the mortar, which is to throw explosive packets onto the enemy's position, also called a conscienceless cannon! It is only necessary to make a large iron bucket with a diameter of more than 50 cm with iron sheets, thicken a layer of wooden planks on the surface hoop, and then connect two brackets to adjust the elevation angle.

The shape is a big bucket, and the legendary conscienceless cannon is transformed from an oil drum, although the structure is simple but the power is amazing! When using, fill it with propellant, separate it with a baffle, and then pack the explosives into it, which can throw a dozen pounds of explosives at a distance of 100 meters, and the enemy will be shocked to death without being blown up!

The second bell is the breech mother cannon, which is actually an enlarged version of the shotgun, because of the current technical reserves and material limitations of the ironworks, this kind of artillery can only be made first!

The production of the sub-mother cannon is simple, first use two 0.5 cm thick iron sheets to bend into a semicircle, and then synthesize a cylinder with a diameter of 10 cm, and then put a section of iron rings outside the cylinder to thicken the barrel, and finally embed it in the open charge chamber, install two wheels on the gun body, and then match a few reloading barrels to complete!

The whole artillery is less than 100 pounds, a person can push and run, easy to move, its main role is for close defense, the firing range is not high, but the firepower is not weak, within 50 meters can block the front 30 meters wide, and it is a breech gun, which can be quickly loaded!

The last is the famous Napoleonic cannon: a smoothbore cannon cast in bronze, which is incredibly powerful, and firing solid cannonballs is a siege weapon! The legendary 12-pounder gun, with a range of more than 1 km, can easily penetrate a 20-platoon infantry phalanx!

And its production method is simpler, first make a mold blank, and then use molten bronze alloy to cast and shape, but now copper is also a precious metal, and it costs thousands of pounds of copper to make a Napoleon cannon at will, and now there is so much money in the iron workshop, so this kind of cannon can only be shelved now!

So Xiao Yao secretly swore that he must work hard to make money and build a Napoleonic cannon as soon as possible, and then there will still be a city in the world that can withstand its bombardment!

Xiao Yao stayed in the iron workshop for more than ten days, which made Li An and his son think that making glass treasures was very complicated, so the Xiao family sold it so expensive, and it was not until Zu Yuan brought the exact time when Chen Shuling, the king of Xing, took office, Xiao Yao and Zhou Chao took the glass treasures that were already full of dust on the side and returned to Li An's house.
