At this time, Yu Xiaotian asked Blacksmith Zhang and them to come and try their hands, so that they could personally feel the power of this weapon they had created with their own hands.

So Blacksmith Zhang and several craftsmen he brought with him also tried firing a few shots each, and they were all surprised, excited, and quite proud.

Because this weapon was made by their hands, but even they could not believe that the power of this musket had become so great just by carving so many rotating grooves into the barrel of the gun.

When the first gun used by Liu Wang was fired twenty times, Yu Xiaotian stopped and did not let people use this gun to fight again.

He had the gun brought over, personally inspected the barrel, observed the inner chamber, disassembled the gun with a small board, unscrewed the screw at the end of the barrel, wiped the chamber with a strip of oilcloth in the whole strip, and brought the barrel to his eyes for a closer look.

After twenty shots, the barrel chamber did not seem to have changed much, but it felt like the rifling was not as deep as it had been at first.

So Yu Xiaotian ordered Blacksmith Zhang to take out the caliper he had brought with him and inspect the inner chamber of the barrel.

After inspection, the diameter of the barrel chamber has been enlarged, so that the rifling in the chamber has begun to become a little shallower.

In fact, this situation is very normal, after continuous shooting, the barrel has to continue to withstand the huge chamber pressure when the gunpowder deflagrates, which will make the barrel expand outward, and the bullet in the barrel is tightly attached to the barrel, which also accelerates the wear of the barrel.

This shows that when this kind of gun is fired, the barrel chamber wears out quickly, and the effective life of the barrel may be quite low, as far as the current situation is concerned, the effective service life of the barrel of this rifled gun, I am afraid that it is at most within 100 rounds, about 100 rounds, the rifling in the barrel chamber should be ground to almost nothing, and the barrel of this gun, even if it can still be used, is estimated to become a smoothbore gun again.

The situation of the smoothbore gun is relatively much better, the chamber pressure of the smoothbore gun itself is not as high as the chamber pressure of the rifled gun, the projectile and the inner wall of the barrel have a certain gap, which will produce deflation and reduce some chamber pressure, in addition, the friction between the projectile and the barrel is much smaller, and the rifling makes the barrel wall thinner, so that the barrel of the smoothbore gun, when using wrought iron, also has an effective service life of hundreds of rounds, and even as long as the barrel wall does not appear cracked or seriously deformed, it can be used all the time without causing too much impact.

However, rifled guns are not good, rifled guns have high requirements for materials, this is not only a problem of high chamber pressure, the key is that the hardness of the rifled gun must be higher, in order to withstand the wear and tear of the bullet in the chamber, and at present, they use wrought iron to build the barrel, even if it is the best fine iron, after all, the hardness of wrought iron is too low, and even mild steel is much stronger than the current wrought iron.

It's a pity that he doesn't have the ability to make steel at the moment, so he can only temporarily use wrought iron to continue to build the barrel, so to put it simply, the production of steel is now imminent, which has become a bottleneck that restricts the continued development of the sea wolf, and he must find a way to break through this bottleneck.

Yu Xiaotian couldn't help but write down another stroke in his notebook, steel! Steel! Or steel!

He then had the gun continue to be tested, and by the time the gun reached thirty rounds, the accuracy began to decrease, and the rifling wore out a little more.

Originally, he still wanted to continue to test the Minie bullets, but unfortunately the first batch of Minne bullets he tried to produce had been used up at this time, so he could only give up and take people back to Tamsui City, while ordering the projectile factory under the jurisdiction of the Ordnance Institute to step up the production of a batch of Minne bullets for testing, and prepare to open the mold to make a mold for casting Minne bullets, and the next step is to mass-produce Minne bullets and begin to supply them to the rifled guns equipped with the army.

It was only at this time that he told Fang An, Meng Fei and others about the principle and specific performance of the rifled gun.

These people are a little confused, and they don't understand some of the professional terms used by Yu Xiaotian, but after today's test firing of the new gun, they know very well that the rifled gun that Yu Xiaotianxin has made is really a very sharp weapon, far leaving many similar firearms in this era behind.

Once they are equipped with this rifled gun in large quantities, then the firepower advantage that the sea wolf has in the future will be completely laid, and no matter who they fight against in the future, the sea wolf will basically be invincible.

Of course, there must be certain prerequisites for this, that is, the number of sea wolves can be inferior to the opponent's troops, but this gap in strength cannot be too huge, otherwise the enemy can still rely on the advantage of numbers, relying on the tactics of the sea of people to drown the sea of sea troops alive.

Yu Xiaotian announced in public that this time he would give Blacksmith Zhang and several blacksmiths and apprentices who cooperated with Blacksmith Zhang to make rifling machines, all of them would be credited and rewarded, and they would continue to improve the newly made rifling machine to make it faster to use, produce higher precision products, and finalize it as soon as possible, produce a batch of such rifling machines, and put them into the gun to put into production of new rifled guns.

And this rifled gun, Yu Xiaotian thought for a moment and named it the wolf's tooth two-type flintlock rifle, referred to as the wolf's tooth rifle, to show that this new rifled rifle will become a sharp tooth of the sea wolf, and the bullet produced is also renamed the wolf's tooth bullet, as for the Migne rifle, Mr. Migne still has nearly two hundred years to be born, don't mention it, now he has plagiarized Mr. Migne's invention, let Mr. Migne, who was born two hundred years later, find another way to mix his life!

The successful development of the wolf's tooth rifle has made the sea wolf finally have a weapon that far exceeds the modern language of this era, whether they produced muskets or cannons, although they have surpassed this era, but the level of technology is not much, only the iron fan casting method can be called the technology of the art beyond this era, in addition, other things, compared to the weapons of the same era, the technology is not too much.

The flintlock pistol is a kind, but the French in Europe in this era have also developed the same type of flintlock pistol, but for various reasons, it has not been popularized for the time being, so that the sea wolf has taken advantage of this kind of firearm, in fact, the flintlock pistol has long been invented in Europe, and the flintlock pistol that Yu Xiaotian has drummed out has not surpassed the skills of the times.

But this kind of wolf tooth rifle (Migne rifle) is really beyond the level of similar weapons in this era, even if someone has tried to produce a rifled gun, has not mastered the mature manufacturing technology, and has not invented the Migne bullet, so this kind of rifled gun even in the West, there are not a few people know about it, as for the promotion, it is more than two hundred years later in the middle of the nineteenth century.

If the sea wolves will mass-produce this weapon in large quantities and equip the troops to use it in the future, then they will surpass the times for two hundred years in terms of infantry weapons, and they can use the techniques of the nineteenth century to deal with the enemies of the seventeenth century, and completely stand at the highest point of technical superiority.

An alcohol distillation workshop was established outside the Tamsui Village, and by the time of the Ming Dynasty, the technique of distilling the liquor to obtain a high degree of liquor had matured, and there were many kinds of earth shochu, so the preparation of alcohol with higher purity was no longer a technical problem.

However, the alcohol distillation technology in this era is not very standardized, the efficiency is not very high, the speed is slow, and the waste is relatively large, this newly built liquor workshop, in the distillation process, Yu Xiaotian put forward some suggestions for improvement, one is to strengthen the sealing of the distillation pot, and the pipe part is made of glass, and the spiral glass jar is used as a condenser, and the condensation part of the pipe outside the introduction of cold water to increase the efficiency of condensation.

As for the others, they continue to use the old method, using ceramics or iron sheets to make them, which is not very difficult, and the biggest difficulty is on the glass condensation pipe.

And now after such a long period of production, the glass craftsmen inside have been repeatedly trying to test the technique of blowing glass in the past two years, and now the craftsmanship is quite good, the glass tube itself is not a difficult thing, it is not effortless to blow it out, and after blowing into a glass tube, the glass tube is heated again and twisted into a twist shape, even if it is done.

So when the glass tube condensing device was transported to the liquor workshop, it caused an exclamation, in the eyes of anyone, glass in this era is an absolute luxury, and Yu Xiaotian is such a big hand, even distilled liquor has used so many glassware, not to mention how much this wine is worth, at least this set of glassware for distillation is worth the old nose money!

With only a small improvement, the efficiency of this set of distillation tools is evident, and the efficiency is much higher than that of the old distillation process, and after the ignition of the ingredients, a clear liquor trickles out of the nozzle of the liquor very quickly.

The whole winery is filled with a strong aroma of wine, so some people can't help but take a little wine and taste it, the alcohol is very high, and the people who taste it spicy grinning and are addicted.

It's a pity that now Yu Xiaotian can't get an alcohol meter, and he can't measure the alcohol content, so he asked the glass field to find a way to try to make a thermometer, and now he only needs to wait for the pure alcohol to come out, and the thermometer can be made, so he can only use a stupid method to distill the liquor twice more before he can determine the purity of the alcohol, so that he can basically get alcohol with a fairly high purity.

Whether the sea wolf is in Nanri Island or in freshwater chicken coops and other places, because they want to save food and meet the needs of emergencies at any time, food is a material under their control, and it is not allowed to make wine in normal times.

But now on the side of Tamsui, sugarcane began to be planted, and a soil sugar house was built, which produced a lot of bagasse, which is a good raw material for winemaking, so Yu Xiaotian decided to open a winery to make wine.
