Regarding Zhou Yonglin's horror and incomprehension, Zhao Hengyi, the owner of the compilation of night school textbooks, didn't care at all.

As a person who has experienced the baptism of the information explosion era, Zhao Hengyi knows very well that if he wants to protect himself, his family, and those who follow him at a special moment in the future, such as when the Great Yan Kingdom collapses, it is not enough to rely on simple force!

Instilling some thoughts in the people around him, Zhao Hengyi has long had this idea.

It's just that this behavior must be done carefully, and it must be done slowly.

Probably two of the hardest things in the world are putting your own thoughts into someone's head and getting people to give you money with joy.

Zhao Hengyi felt that he was doing a good job, whether it was Jiuhua Yulu or cheap cloth, or even small-scale high-grade wine, he could achieve this purpose.

However, it is very difficult to stuff one's own thoughts into the heads of others.

Although the Great Yan Kingdom is extremely decaying, like an old man who is about to die, and the smell of death is exuding from all over his body, it has not completely collapsed after all.

Zhao Hengyi couldn't use some radical methods, he didn't want to force the county order Liu Rui to lead troops to encircle and suppress him.

However, this does not mean that Zhao Hengyi has given up the idea of carrying private goods in night school.

Anyway, the night school in the village is more similar to a literacy class, and there are not many people who can understand what the gentleman says.

But it is precisely because of this that some budding things have been quietly planted into everyone's minds.

The evening school in Elm Bay has been expanded and now has five gentlemen, divided into different classes to carry out phased literacy for everyone.

Some clever young students have been able to master simple arithmetic and writing, and it is enough to act as clerks in the workshop.

Night school is not mandatory, and it is more of a way to let everyone take the initiative to learn, but some special positions and special people must master certain knowledge within the specified time, such as Zhang Daniu, who is bullish and coaxing.

Zhang Daniu is a pro-apprentice of the owner all day long, except for the village chief and a few elders, even if he is the manager of each workshop, he sees it with his nostrils facing the sky, and he is extremely arrogant!

But this product does have arrogant capital, and in the newly built smelting workshop, in addition to Wu Ren, who was born as a prisoner, it belongs to Zhang Daniu, who is a fool of the goods, and has superb craftsmanship!

The most important thing is that this product actually mastered the means of refining tungsten steel ahead of Wu Ren!

At the beginning, in order to deal with the attack without a shadow, Zhao Hengyi took Zhang Daniu and Wu Ren to reluctantly create a fire gun, and directly killed the master of the rivers and lakes without a shadow.

But this firearm is extremely rough, and even in Zhao Hengyi's opinion, this thing may be more appropriate to be called a trumpet hand cannon.

The caliber is very arbitrary, and the pipe body is very thick in order to pursue not to explode, and the weight is seriously exceeded, which is not suitable for normal use.

The charge is troublesome, the steel balls and iron sand are not convenient to fill, and it is very easy to burn themselves when using it...... Overall, this is a failed emergency product.

If that fire gun had wisdom, he would definitely scold Zhao Hengyi, he was called Xiao Tiantian at the beginning, but now he is called Mrs. Niu......

But with the successful development of tungsten steel, with the continuous delivery of tungsten ore from Hengtong firm, Zhao Hengyi is no longer satisfied with this rough and troublesome simple firecracker.

He even had a bold idea to directly step over the front loading gun to study the rear loading gun, directly separate the arquebus, and make a rear-loading gun similar to the rifle in batches by leaps and bounds.

Once successful, Zhao Hengyi is confident that he will form an armed force that will crush this era.

It's a pity that the ideal is very plump, but the reality is incomparably skinny.

The firebolt is no better than the hand crossbow, and there are countless technical problems.

Especially Zhao Hengyi's steps were too big, so it was inevitable that he would be light, and led Zhang Daniu and Wu Ren, the two right-hand men, to stay in the smelting workshop for a few days, and finally reluctantly admitted that he was too whimsical.

On the contrary, Zhang Daniu couldn't understand why Shizun had to make such a sharp weapon as a fire gun into a thin tube? And to engrave a spiral rifling in the tube?

Don't you understand that the bigger things in this world, the more powerful they are?

This special meow deserves to be you!

Zhao Hengyi never thought that Zhang Daniu, a fool, would comprehend the profound idea that caliber is justice without a teacher!

However, the way of thinking has changed!

"Da Niu is right, since we can't make small-caliber guns, why don't we just get some large-caliber guns to use!"

Zhang Daniu, who was praised by the master, scratched his smooth head and giggled, this bastard found someone to scrape himself because it was too hot in the smelting workshop!

In this era of parents who pay attention to the body's hair and skin, I have to say that Zhang Daniu is really willing to sacrifice his blood in order to forge!

"It's better to be taught by the teacher! Otherwise, I am afraid that I would still be guarding the blacksmith shop to make firewood knives and hoes. ”

Zhang Daniu's shameless appearance made Zhao Hengyi have a toothache.

It's obviously a fool, so I have to learn from others to praise it, hey, it's really numb!

Just do it, Zhao Hengyi temporarily gave up the idea of developing a new type of firearm, and instead thought about getting a few artillery pieces out.

Of course, the firecracker still needs to be made, but it will not be forged in large quantities, it is only an experimental one, and it can be prioritized to equip the escort team.

When more craftsmen are gathered, enough technology is accumulated, and stable and easy-to-use firecrackers are thoroughly manufactured, Zhao Hengyi will be manufactured in large quantities.

In fact, the main technical problem of the gun is the construction of the gun tube and the research of the fixed ammunition.

If you want to overcome these technical problems, it will be difficult to complete them in a short period of time, and the firebolt will be used as a secret weapon similar to hole cards for a long time in the future, and even in the eyes of the guards, it may not be better than a hand crossbow.

But when it came to artillery, Zhao Hengyi suddenly had confidence.

Now in his hands, he has tungsten steel, an excellent alloy metal, and the gunpowder formula is not bad, and it may be difficult to manufacture smokeless gunpowder in large quantities, but it is enough to meet the consumption of a few cannons.

Besides, Du Temeow's playing caliber is not only righteous, but do you still care if the gunpowder is smokeless, and do you still care if there is any residue after the gunpowder burns?

Don't make a fuss, as long as the caliber is big enough, after a shot, it's no problem for people to drill in and clean up the debris!

The so-called modern high-tech artillery, Zhao Hengyi is not qualified to build, and it is impossible to have that technology, but a simple and powerful artillery can really be made with his existing conditions!

In his previous life, Zhao Hengyi had heard of an extremely people-friendly artillery, and his comrades affectionately called that thing...... No conscience cannon!
