With the order of Tulu Borot, the eldest son of Dayan Khan, the Tatar thieves flocked to the border, and the horses under their crotches seemed to sense the savage heart of their masters, and they also neighed and spewed out two white gases, and the hooves of the horses trampled on the frozen ground, splashing up puffs of dust.

Tuluberott's chest stirred, he rode his horse and took the lead, as long as this wave of southward movement could plunder enough supplies from the Han Chinese, the lord of Tatar would surely be more satisfied with him, and there would be more voices in support of him.

He didn't need to be very good, just a little better than the Turusburott who coveted the throne as much as he did.

At this moment, Tulu Borot even knew that in the territory of the Ming Dynasty, many Han people were already stationed, waiting to resist his attack, but he was fearless, and no one could stop him.

The iron horse galloped wildly, and soon it was fierce, and it crossed the border like a sharp arrow.

But just after the Tatar barbarians rushed into the territory, a group of Ming cavalry from afar caught up.

The cavalry, dressed in chain mail, was a mile away from them.

Then out of it came a man dressed in Han costume, but clearly Tatar-looking, and shouted loudly.

"Your Highness Tuluberrot, my Lord Supervisor has brought the will of His Majesty Hongji Daming and has come to convey it to you."

Obviously!

Who is this person? Tatar traitor!

That is, Tatar?

Tuluberrot rushed to the front, but did not hear the man's words, but seeing that the Han cavalry on the opposite side did not meet him, he raised his horsewhip and ordered the Tatar warriors to stop.

The speed of the gallop was very strong, and it was enough to rush forward a distance of about 100 meters before the Tatar iron rider stopped.

On the Ming side, the soldiers held long knives in their hands and were ready to fight at any time.

But the supervisor said to the Tatar traitor: "Come with me." ”

He has been in the army for five years and is very sophisticated.

The Tatar traitor nodded, and walked tremblingly at the front, while the supervisor held the decree in his hand, and the royal horse followed.

When he reached the distance from Tuluberott, the Supervisor was not forward, but he opened the decree and recited it solemnly.

"Fengtian carried the emperor's edict that the Ming and Tatars have been friends for many years, and there are mutual contacts, I heard that the Lord of the Tatars, Dayan Khan, has seven sons, but I learned that there is a difference with my Ming etiquette, except for one son to inherit the throne, the rest of the sons were exiled for a hundred miles, which is very unbearable.

Therefore, I appointed myself Tulu Berott as the candidate of the Horn of Tatar, and gave me a hundred taels of gold and a thousand deniers of corn as a token of gratitude. ”

The Tatar traitor repeated the words of the supervisor in Tatar, and he spoke very slowly, for fear of omission.

Tuluberrot didn't think about it at first, but when he heard that the emperor of the Ming Dynasty had actually made himself a Tatar horn, his heart was pounding.

As the eldest son of Dayan Khan, Tulu Borot has always been very dissatisfied, why he is the eldest son, but he still has to go through a competition to move towards the throne, instead of succession.

Even, for countless nights, he wanted to kill those disgusting younger brothers.

But right now, the emperor of the Ming Dynasty canonized himself, isn't this just acknowledging his status?

With this, do you still need to compete?

The whole of Tatar will be his!

Whoever dares to stop him will let those people taste death.

Turuberoth's chest burned with ambition, and he roared greedily at the rich Ming, but soon he hid this greed.

"Take the food and gold they offered, and we'll go back."

Turuberrot's ambitions had swelled so dramatically that he had even imagined that when he returned to Tatar under the guise of a horned candidate, he would have countless supporters.

That position must be mine!

The Tatar barbarians, who attacked like evil wolves, hurriedly left the border of the Ming Dynasty.

It's just that if Tulu Borot knew that Emperor Hongzhi not only made him a prince, but even his younger brothers were not left behind, his face would definitely be wonderful.

But at that time, it was already too late, and even if he reacted, this was the poisonous plan of the Ming Dynasty, and the Tatars who supported him would not allow him to stop.

The whole of Tatar will fall into a period of internal friction.

And this time will continue until the little Tatar prince Dayan Khan chooses his successor.

……

The crisis on the border of the Ming Dynasty was resolved by the strategy he offered, but Du Shen did not know that he was in the chalk workshop at this time, observing the situation of the hearth.

After several days of hard work by the craftsmen, the workshop has been built, and this is the first firing, which has been carried out for half a day.

The foundation of the new academy has been dug up, and the chalk workshop is located in the western part of the academy, but the reason for this is because it is not reassuring to be placed elsewhere.

In order to ensure the stability of the hearth, Du Shen deliberately built it according to the shape of the egg when he ordered the craftsmen to make it, so that the temperature in the workshop was very high.

Although everyone in the workshop was wearing thin shirts, they couldn't stop sweating.

"Master, can you take out this batch of stones?"

Zhang Hao licked his chapped lips and stared at the hearth.

Du Shen stretched out his right hand and said lightly: "It should have been almost burned." ”

With a wave of his hand, he ordered the craftsman to turn on the furnace.

There are many pebbles placed in the furnace this time, and the difficulty of firing is not small, and if the hearth is powerful, it will get a satisfactory return.

Soon.

The hearth was opened, and a cloud of sparks and choking smoke erupted.

In this era, whether it is a blacksmith or other workshop, if you want to increase the temperature in the furnace, you basically use natural coal mines as fuel, so billowing smoke is the norm.

The smoke from the burning of coal is poisonous, so the status of blacksmiths in ancient times is not as high as imagined, and it is a work that hard-working people can do.

Du Shen coughed a few times, and then ordered: "Come on, do it." ”

As the craftsmen remove the burned pebbles from the furnace, the temperature in the entire workshop increases so much that it is as if they are about to roast people on a fire.

The scorching turbidity was extremely uncomfortable.

Du Shen complained bitterly, and hurriedly took his apprentices out of the workshop.

After they took a big breath of fresh air and the cool breeze drove away the heat of their bodies, the craftsmen reported their results.

"Sir is really talented, the effect of the hearth designed is simply beyond our imagination, the stone is fired perfectly, as long as it cools, it can be used at any time."

"This is not my work alone, thanks to you, otherwise it would be difficult to build this hearth."

Du Shen nodded, smiling approachably.

The reason why the hearth works so well is that four ventilation ducts are added to its foundation, and the workshop built can withstand the heat.

At this time, the third apprentice Xu Pengju asked: "Master, but there are not many stones in this batch, if you want to make chalk, I'm afraid there aren't many of them, right?" ”

The question is acute.

There is such a river near Dujia Village, although there are many pebbles, but it takes a lot of effort to transport them, although this batch of stones is sufficient, but the calcium sulfate content is very low, so the refined gypsum will not be too much, how much chalk can be made, it is still unknown.

However, Du Shen has already had a way to deal with this.

Immediately, he smiled meaningfully: "Disciples, whoever said that to make chalk must be made entirely of plaster." ”

Wouldn't it be the same with some churned hay?

Now it's time to open a store, but it's not appropriate to just sell chalk, but you have to get the quill straightened out.
