Tax exemption is not the best way, the best way is to make them rich and make their lives more fulfilling than before, rather than relying on their thousands of years of precipitation to engage in the same philanthropist to help others, which has proved that they are not capable and do not have this mood.

Because the so-called Turkic national teacher is about to come.

The letter of the Zhao family has arrived in Beiping City, the national teacher has already crossed the border, these people have begun to come towards Beiping City, obviously at this time His Majesty's side is also about to leave, although it is not a good choice to come out to cruise in the cold winter, but there is no doubt that there are many fewer things in winter at this time.

It is obvious that both sides have chosen this important time node as the basis for negotiations between the two sides, but this kind of time node is beneficial to the big win of the dynasty.

At least in Li Hang's view, those nomads will either have to endure hunger or have to negotiate peace immediately, and now they are not qualified to put forward conditions.

Li Hang thought so, and it is estimated that those people in the court also thought so, otherwise even they would not dare to prevent the other party from coming over to negotiate at this time.

National Teacher ......

Hehe!

A person who plays with religious superstition dares to be a messenger? I'm afraid it's not the Turkic Khan Shi Lezhi.

Li Hang sneered and looked at the northern sky.

Winter is here, and now is the time to start walking into the cold winter.

Now the things in my hands have not been fully developed, if I can develop steel, I can do whatever I want when the time comes, not to mention this kind of lobster armor and short sword of the old era, even if it is a super long spear six or seven meters long, I can make it myself, if it can be combined with black powder......

Hehehe!

The Turks are an egg, as long as they develop an army at the level of lining up to shoot, the Turkic cavalry can be directly beaten into the cold palace.

At that time, as long as a hollow phalanx is formed, those cavalry will come to send them to death.

However, I haven't clicked on this line of skill trees yet.

When you make steel with something like charcoal, I always feel that the effect is a little worse.

And that kind of metallurgical coke is not only a fuel, but also a chemical raw material, and the carbon element in steel is actually like this.

Think about it, the carbon content of steel determines the hardness of rigidity.

For example, the carburizing process of steel, this process is not only a simple technology made of pig iron, but also the steel made from coking coal is definitely stronger than these pig iron.

And if there were a blast furnace, plus the production of molds, then the efficiency of making some simple weapons would be ten, hundred, or even a thousand times more efficient than that of today's blacksmiths who made them by hand!

Because a furnace is directly poured and molded, it is much easier than those to be built.

In wartime, production is supreme, as long as a large number of weapons can be built, even if it is not a cadre, as long as it is a qualified product.

Thinking of this, Li Hang pinched his chin with some curiosity.

This kind of thing can only be used in the early stage, and if it is used for a long time, it will actually reduce the quality.

The kind of things made by the earth-made steelmaking method are largely used to make some basic household utensils at best, and even this one is enough to choke.

If the harmful elements of steelmaking are not eliminated, this kind of steel is even inferior to some well-built iron equipment.

Among the things that Li Hang can take out at this time, there is really nothing that can surpass steel.

No matter how hard the cans blow, in fact, steel is a good thing in the actual sense.

Because canning is, at best, a branch of biology.

Steel, however, is a different discipline.

That is materials science, which dominates other disciplines and is the most basic discipline.

It can be said that every material change will advance the evolution of other things.

Only when materials science develops, will other disciplines begin to develop.

Once you have a blast furnace, you can even refine farm tools and weapons on a large scale.

At that time, not only those farm tools can be used for more than ten or twenty years, but even many front-line soldiers can become real invulnerable monsters.

At least for those nomads.

It's a feeling when you think about it.

However, at this time, the workshop did not stop, because at this time, whether it was glass or all kinds of things, it was a small scale of experimental production, especially those glasses, which have now been made in several colors.

Not only have the red, orange, yellow, green, blue, and purple colors been made, but now they are starting to prepare for the production of colorless glass.

Colorless glass is a very important link, in a sense, colorless glass can be regarded as a great product, because it is a necessary thing for many observation experiments.

Whether you're making a test tube or a beaker, whatever it is, you have to use a colorless transparent glass to observe.

In addition, this kind of thing can also be made into a measuring cup, which is a must for many chemical experiments.

And now......

"Hop Hop Hop!"

Zhou Xin clapped her hands excitedly, because at this time she was excited to see the chessboard, because the glass ball in her hand could jump directly to the other party's house by relying on the bridge with Li Hang's glass ball.

And at this time, Li Hang was completely defeated on all fronts!

The two little girls each held a glass ball in one hand, and their eyes were all staring at the chessboard.

"Brother-in-law, why is this chess piece like this, why do you want to jump the chess pieces into the opponent's circle first!"

"Well...... In fact, the main thing is to play, I'll do a flying chess game to teach you to play! ”

The life in winter is really a bit unrefreshing, sitting around the fire, Li Hang can only play this chess game with them.

After all, this kind of chess game is the most suitable.

After all, no matter what kind of movement it is, you can find a shadow from the chess pieces.

"Ludo chess? Can you fly? The little girl had caramel in her mouth, and there was a thoughtful expression on her face.

"Fly, it's impossible, what, Xiao Xin still wants to fly!" It's not that hard for humans to fly, but it takes courage.

Whether it is a paraglider or a parachute, it is considered to fly, but it requires speed and height, so high jump, Nimana is not something that ordinary people can do, not to mention that even if it is the simplest and easiest to achieve hot air balloon, it also needs to have enough strength.

Even if you are very powerful and not afraid of height, you also need to withstand falling, don't think this is talking, this is not a simple talk, because at this time, once you are not careful, it is very easy to have an accident, but flying this kind of thing is always attracting human beings.

"I'm afraid that only immortals can fly." The little girl looked out and said thoughtfully.

But soon she noticed the dark shadow in the distance outside.

"Brother-in-law! Let's see, what's that? ”

Li Hang stood aside and looked over, and the row of war horses was quite eye-catching.

It's the border army! The border army is coming, and the border army is coming at this time, which means that the so-called national teacher is coming.
