The most powerful tyrant of the Sui Dynasty

Now the Great Sui has almost begun to advance towards the road of the Iron City, although the Great Sui has mastered a lot of iron, copper and gold from other countries through various sales, and even the collection of aluminum ore veins that are not known to other countries.

But after all, this is manual mining, and the efficiency is extremely low.

Acting in other countries, it is impossible for Yang Guang to send mechanized troops to excavate, let other countries know, and they will definitely stop it.

After all, other countries are not stupid.

They are willing to use all kinds of mines as insurance policies for Yang Guang, that is, they have calculated the value of the amount that Dasui can obtain.

Of course, even if the efficiency is low, Yang Guang will accept it.

These are the energy base, and the value of them is not yet realized by countries, and when they do, they will soon become the most important reserve resources of a country, and it will not be so easy to grasp by then.

However, according to Yang Guang's plan, I am afraid that before that, the Great Sui will definitely take down these veins completely.

"Master, this cannon is easy to imitate?"

Wang Anshi asked on the side, he didn't cover his ears, he kept buzzing just now, and he didn't want to get better, just when he heard Yang Guang's words, he immediately asked.

From Wang Anshi's point of view, you can just see the whole picture of the cannon.

A large iron barrel, there may be two layers in it, one is filled with gunpowder, and the other is the iron ball that Liu An just put in, as for the lead, it is easier, the place where to make firecrackers can be made, and it can be made thicker.

Thinking of this, Wang Anshi seemed to feel that he could do it.

Zhang Juzheng beside him was a little concerned about Wang Anshi's loud voice, and stood away slightly, but he was also very nervous about what Wang Anshi said, staring at the face of the public defeat.

"Where is this thing so easy to imitate, it's really a pipe dream!"

Hearing that someone wanted to imitate their painstaking brains, the public immediately became angry.

But having said that, Gong Defeat still looked at the cannon nervously, with a hint of thought on his face.

After all, this thing, it seems, is so simple, it doesn't seem to have any technical content at all. In fact, it was the same, at that time, Yang Guang gave them a rough idea of the structure, and it was produced.

Most of the time later, it was about improving and experimenting with power.

This process lasted the longest, and it was also the place that made the three masters anxious the most.

Fortunately, the Sui Emperor arranged for people to enter the Southern Song Dynasty as soon as possible to mine the mineral veins of the Southern Song Dynasty.

The Southern Song Dynasty is a good place, and the Xishan Coal Capital of later generations is only here. This is where the heat gathering needed for smelting steel is used. Of course, all this is known by Yang Advertising, and everyone in the world knows that black coal is combustible, but he does not dare to use it more.

After all, this is not refined, and a lot of toxic gases will be released under combustion, and once people inhale too much, they will die.

But these difficulties are too easy for Yang Guang, the poisonous gas released in it can be neutralized by the nourishing gas, and it is easy to do it, get some yellow mud, crush the coal and mix it into the wood residue, and wait until it is dried, it is natural honeycomb coal.

Not only is it not toxic, it is also smoke-free.

This method not only greatly solved the problem of a large amount of fuel required every day, but also gave Yang Guangxin inspiration.

Sell coal.

Winter is approaching, and sweaters alone are enough to protect the south from the cold. But every family still has to rely on fire to survive the harsh winter, but although the world is full of wood, but also have to go into the deep mountains to cut down, if you encounter wild beasts that come out to hunt in winter, most of them have no return. After all, the mountain is the home of the beast, and where are the ordinary people opponents.

Now with this coal, once again a big problem has been solved.

And most importantly, it solves the problem of steel smelting.

"Aiqing, don't get excited, the essence of this thing is not outside. "

Yang Guang didn't expect that even the public loss was a little shaken, which is not scientific.

You made it, and you don't know the technical content of it? If it can be copied exactly, it will take you so many days to study it.

Yes, Yang Guang is sure that other countries can imitate it.

It's just that the imitation version may be a one-time use, and it won't even be used a few times, and it will be finished.

There is no other reason for this, it is the steel used in the casting of artillery.

This is not ordinary iron, at the beginning of making artillery, Yang Guang first asked the three masters to use various metal raw materials to mix, and then continuously refined cold-rolled steel.

This thing is also very simple, that is, iron, copper, tin, germanium and other rare metals are specially proportioned, and then quenched at high temperature, and processed into steel.

Its hardness is not comparable to that of ordinary steel, and at the same quality, it is not much harder than the known gold-like hardness.

It's easy to say, but to make it, you need to have a recipe.

This recipe is naturally already a secret of the Great Sui. It is difficult for ordinary people to even know the existence of this thing, and like pearl rice and dragon tooth wheat, everyone thinks that it can only be born in the king's land.

So Yang Guang didn't worry about them copying at all, even if they made it.

First of all, the iron cannon is far less powerful than the cannon of the Great Sui, after all, the power of gunpowder is absorbed by the miscellaneous iron inside, and the second one, if it is used too much, it will definitely explode.

For the principle, Yang Guang explained a little, and the most essential thing is the body of this artillery.

"Your Majesty, since the essence of this thing is in the cannon itself, it must not be imitated. Not only can the production technology of steel not be leaked, but the formula must be kept secret. "

Zhang Juzheng came out of the queue and immediately admonished.

He was a little excited and incoherent, mainly because he suddenly saw such a divine soldier born in the Great Sui, and it is conceivable that this will be sold.

Well, as soon as this thought was born, Zhang Juzheng gave himself a slap in the face.

How can such a divine weapon be sold?

"Your Majesty, can artillery be sold?"

But without waiting for him to think about it, Liu Hua couldn't help but ask.

After a trip to various countries and a lot of money from selling weapons for the Great Sui, Liu An's life ambition began to change.

As an envoy, he has made great contributions to the Great Sui, and now Liu Hua also has a high status in the foreign teaching department.

"Your Majesty has atoned for your sins, and the minister has spoken in vain. "

When the words fell, there was silence all around, and everyone's faces changed suddenly. Liu Hua is still a human spirit, and immediately knows that he has said the wrong thing, if he sells all these things, if the five countries are united again, it will not be to lift a stone to shoot himself in the foot.

"No, this largest gun naturally can't be sold, but other medium and small cannons can. "

Yang Guang smiled slightly, and then said.

Of the few shots that have just been tested, only the cannon can shoot a cover of sixty meters, and as for the rest, the power is much stronger than that of the catapult and the ballista cart, but that's it.

For Yang Guang, the most important thing is in hand, and the rest must be turned into silver as soon as possible. _
