For the study of firearms, Zhao Hengyi has never given up.

Although compared with the hand crossbow, the fire gun that can be created in Elm Bay at the moment is not outstanding, and even in actual combat, the efficiency and power are pressed on the ground by the hand crossbow and rubbed hard, but Zhao Hengyi knows in his heart that the fire gun is the king who will affect the trend of the battlefield in the future.

In fact, the barbarians who are currently ravaging the frontier and making the entire Great Yan Kingdom anxious, in Zhao Hengyi's opinion, Yuanyuan does not have the strength to match their results!

To put it bluntly, this is a worse era.

The barbarians are already very bad, and there is no king who can bring all the tribes under his command on the steppe, and he fights everywhere with his surname and tribe as a unit, and his own internal infighting is constant, and the small tribes live in the shadow of being swallowed up by the big tribes, and the big tribes often have friction because of various grudges.

Such a barbarian, in Zhao Hengyi's opinion, is really like a local chicken and a dog.

It can only be said that the reason why the barbarians are able to be arrogant is entirely because the Great Yan Kingdom is worse than them.

And the fact that the Great Yan Kingdom was able to continue to maintain and prevent this already decaying big house from collapsing was also because the barbarians were too rotten.

Everyone doesn't laugh at the second brother, it can only be said that they are all very lucky, and there is no strong third-party force around them.

However, after experiencing Kou Bian who was confused on both sides this time, I am afraid that this delicate balance will be broken in a very short time.

The individual strength of the barbarians is very strong, and they just want to grow up on horseback, and being skilled in bows and horses is the basic requirement for survival.

Once there is a war, the barbarians recruit troops in the tribe, as long as it is a man, even a child of eleven or twelve years old, but anyone who can pull a bow and ride a horse, can be pulled to the battlefield to hang the army called Huazi of the Great Yan Kingdom.

At the moment when Dayan's domestic turmoil is rampant and the situation is unstable, Zhao Hengyi has always been wrapped in a deep sense of crisis.

He is constantly increasing the military strength of his subordinates, and the imaginary enemy has always been a barbarian race that will eventually wreak havoc on the world.

This matter brought back countless goods, grain, and slaves from the Great Yan Kingdom, and the strength of the barbarians will surely usher in a rapid outbreak stage!

And what will happen to this will inevitably be the ambitious people who take the initiative to break the current mode of survival on the grassland.

As fast as three years or as long as five years, it is very likely that there will be a co-leader of the heroic type on the grassland.

And once such a person appears, he will inevitably set his sights on the precarious Great Yan Kingdom.

When that time really comes, I am afraid that the tragedy of Lu Shen in Huaxia that has appeared in history will be staged again.

Zhao Hengyi is not the only one who has this judgment, there are already families who have begun to organize large-scale group exercises, to put it bluntly, with the background of hundreds of years and thousands of years, to prepare for the chaotic scene that is very likely to occur next.

Zhao Hengyi didn't have the ambition of those big families to compete in the Central Plains, he just wanted to protect himself.

But with the expansion of his power, various circumstances pushed him forward, and where he would eventually go, Zhao Hengyi himself couldn't tell.

But that doesn't stop Cho from doing what he thinks he should do.

The power and efficiency of the hand crossbow are mostly reflected in small-scale conflicts, and the real battle array attack, the hand crossbow is definitely not comparable to the firearm.

Therefore, even if he came up with a big killer weapon such as a conscienceless cannon, Zhao Hengyi still persistently invested a large amount of money and continued to accelerate the research and development of firearms.

Even with the development of the situation, Zhao Hengyi's requirements for firecrackers have been repeatedly reduced, after all, just relying on the current industrial strength, it is really difficult for some strongmen to make high-tech firecrackers in one step.

Moreover, Zhao Hengyi, with his own knowledge, is very clear that he has made the smelting workshop continue to develop firecrackers in order to build a production line that can meet the needs of large-scale assembly.

Perhaps with the help of skilled blacksmiths such as Zhang Daniu and Wu Ren, they can make extremely high-tech firearms, but only three or five such weapons cannot change the big situation.

In the end, after repeated discussions and deliberations, after weighing the performance, durability, manufacturing difficulty and other factors, the fire-type flintlock pistol was finally selected as the project to be tackled in the smelting workshop.

This kind of front-loading firearm is already the most mature and closest to perfect style of front-loading guns that Zhao Hengyi knows.

The rear-loading gun is not unfragrant, but it is completely unattainable with the current industrial strength.

Zhao Hengyi had heard a saying before that the history of the development of gunpowder was the history of the development of gunpowder, but in fact, he really realized that even if his head was full of all kinds of formulas and technologies, if he wanted to transform all these things into real strength, he needed more than just knowledge to lead the world!

Under Zhao Hengyi's repeated insistence, there must be a spiral rifling in the barrel of the new firecracker, and the projectile adopts a long garden-shaped shape.

Fortunately, the smelting workshop is now able to mass-produce the so-called tungsten steel, an alloy that Zhao Hengyi has high hopes for, is a garbage that does not meet industry standards in the future, and at present, it is enough to subvert the treasure of the entire era!

Prior to this, the hydraulic hammer forging machine after being modified by the demon made a large number of tungsten steel armor through sheet metal after paying the price of three apprentices taking turns to fight, these styles are simple, and even rough armor, although it did not usher in the highlight of the battlefield, but it was not wasted, and now it has become the load-bearing equipment for the daily training of the team training members.

It is precisely because of the success of the hydraulic hammer forging machine that everyone in the entire smelting workshop is extremely convinced of Zhao Hengyi's decision.

Especially under the propaganda of Zhang Daniu, a fanatical disciple, it seems that as long as Zhao Hengyi says that something can be successfully made, then everyone will think that this thing must be able to be made.

What couldn't be successfully made for a while was not that Zhao Hengyi was wrong, or that his gang didn't find the right way, the craftsmanship was too poor, and I was sorry for the trust of the owner.

Zhao Hengyi's stimulation of this atmosphere can't be said to be good or not, but the efficiency of the smelting workshop is very good, just rush this, Zhao Hengyi has been holding back and ignoring Zhang Daniu's living treasure.

The pipe created in this smelting workshop is the result of many tests using a special drill bit.

The black and heavy gun tube is polished very smooth, and the inside of the tube has a spiral rifling that fully meets Zhao Hengyi's requirements, and the most important thing is that through the efforts of Zhang Daniu and Wu Ren, this gun tube can be fully produced on a large scale!

Even, even how to mass manufacture in the future, these two blacksmith disciples under Zhao Hengyi's sect have designed it.

A batch of special drill bits is made first, and then connected to the hydraulic drive facility, and when making the gun pipe, it is completely possible to use a group of people with no technical skills to operate!

The drill bit is driven by hydraulics, and the worker places the solid tungsten steel rod on the fixed frame and slowly pushes the ...... The finished product is out!
