From spring to summer, the situation in eastern Liaoning and the grasslands is very good.

In Liaodong, Brother Suhan has successfully controlled the original territory of the Jurchens in the East China Sea, while the Jurchens in Haixi saw that the wind was not in the right direction, and finally chose not to help each other.

So the situation became that the fierce brother Suhan led the East China Sea Jurchen and his brother Meng's brother Timur's Jianzhou Jurchen to confront each other.

In the original history, in the spring of the third year of Yongle, the Jurchen tribes should have been unified, and then the Meng brother Timur who wrote to the Ming Dynasty to request the attachment was now trapped in Jianzhou and could not move.

However, it is worth mentioning that the fierce brother Timur still requested the excerpt attached in the early spring of this year.

It's just that Liaodong's excerpt must pass through Beijing, so it was detained by Chen Kan without the slightest hesitation.

On the grassland, with Wu Gao's secret support and support, the battle between Arutai and Mahamu has also reached a white-hot level.

It is said that a large number of cattle and sheep have starved to death on the grasslands.

Just because the herdsmen have been arrested by Mahamu and Arutai, they are bound to fight to the death on the grassland.

In this regard, Chen Kan's response was to directly repair a letter to Wuliang Ha Sanwei.

Wuliang Ha Sanwei is the famous Duoyan Sanwei in history, Zhu Di can successfully steal the crystal and force Jianwen to burn the palace, Wuliang Ha Sanwei is absolutely great.

But at the beginning, Duoyan Sanwei was a mercenary who only recognized money and not people.

That's right, mercenaries.

Originally, Duoyan Sanwei was the most powerful army in the hands of Zhu Quan, the king of Ning, and was bought by Zhu Di with money to work for him.

And the reason why Zhu Quan made rice with Zhu Di was also because Duoyan Sanwei hijacked him against the water.

Chen Kanxiu's purpose for Wuliang Ha Sanwei is very simple, since many people on the grassland have died, why not spend money to hire Duoyan Sanwei to fight.

With the green light given to him by Zhu Di, it didn't take long for the leader of Duoyan Sanwei to reply to Chen Kan, expressing his willingness to cooperate with Chen Kan.

And in a very short time, the news of their willingness to sell was spread throughout the grassland, provided that it was to see who would pay more.

As soon as this news came out, both Mahamu and Arutai couldn't sit still.

Da Ming is a foreigner, and he has no qualifications or reason to meddle in the internal fighting on the grassland, otherwise he will lose his moral name.

But Duoyan Sanwei is different, they are Mongolians with good roots.

Although he voted for Daming, he was more of a cooperative relationship with Daming, and there was no way to change the race.

What's more, Duoyan Sanwei is a notorious mercenary, no matter what righteousness or status, they don't care who is orthodox, they only care who gives more money.

Now the two were in a hurry, and the documents asking for help were handed to Daming one after another, and Ma Hamu's words were more earnest, asking Daming to support them with a large sum of gold and silver, saying that after he conquered the big tent of the gold family, he was willing to return all the books, antiquities, ritual utensils, gold, silver, jewelry, etc. that the royal family of the Yuan Dynasty rolled up to the grassland.

Arutai was about to be much more arrogant, and directly told Zhu Di to let him manage Duoyan Sanwei and let them not bite indiscriminately, otherwise he would fight for the position of Yuan Ting Taishi, and he would also send troops to invade the Ming border first.

How could Zhu Di be the one who was threatened like this, so he directly replied to Arutai, the content was very simple, bluntly saying that Duoyan Sanwei was a Mongol and not under my control.

When you evacuated the Central Plains, you took away the wealth accumulated in the Central Plains for a hundred years, and you can completely take out part of it to ask Duoyan Sanwei to deal with Mahamu.

A letter directly made Arutai furious.

When they evacuated the Central Plains, it was good to take away the century-old wealth accumulated in the Central Plains, but after so many years, Yuan Ting had already cultivated a large number of Bayi nobles who could only cook and know nothing else, and those riches had already been almost divided.

Arutai wants to put down the rebellion and dominate the steppe, and that's no problem.

But he dared to think crookedly about Lord Bayi's wealth, and the next day his position as the Grand Master would have to be swept to the end.

Zhu Di's murderous and heart-killing play can not be described as six.

At the same time, news came from Nanjing that Zheng He's fleet had set sail.

There is also a bank that Beijing people have been thinking about, and it has finally landed in Beijing.

All in all, Chen Kan never imagined that everything could go so smoothly.

But as soon as he thought of these plans made by him from the commanding heights of history, those unreasonable places suddenly became reasonable again.

Of course, Chen Kan has not been idle these days, since he began to teach Hua Shi and Zhu Zhanji in the second stage, Chen Kan has been buried in the mansion.

When Chen Kan taught Zhu Zhanji and Hua, the two of them taught Zhu Zhan Yan again, and after cooperating with each other, Zhu Zhan Yan's progress actually caught up.

Today, Chen Kan ended his teaching after demonstrating to the two what an air cannon is.

The summer in the north is very hot, different from the humid heat in the south of the Yangtze River, and the heat in the north is the kind of dry heat that hurts the nasal passages.

The hot weather made people feel no longer able to lift their spirits, so the three masters and apprentices who had just finished the class were all tired.

"Hours, go and see the chilled fruit in the well."

Chen Kan waved his hand, motioned for Hua Shi to fetch the fruit, and then came to the pavilion in the inner courtyard with Zhu Zhanji and sat down.

Zhu Zhanji stuck out his tongue and gasped: "Teacher, when will the microscope you said be made?" ”

Chen Kan wiped the sweat from his forehead, shook his head and said: "The purity of the glass produced by Daming is not enough, and the polishing technology is not at home, but I am afraid it will take a while." ”

The microscope is an indispensable teaching tool for Chen Kan at this teaching stage, whether it is biology, physics or chemistry.

Before making a microscope, Chen Kan felt that even Leeuwenhoek could rub the microscope by hand, and he was not a traverser yet.

But the final result was a slap in the face, and Chen Kan couldn't even get a magnifying glass, let alone a microscope.

Fortunately, there are many skilled craftsmen in Daming, so Chen Kan handed over the work of making microscopes to the craftsmen who fired glass in Daming.

Zhu Zhanji's face was a little disappointed, Chen Kan told him that the so-called Buddhism's so-called one flower, one world, one leaf and one Tipu was true, and he had always been skeptical about it.

Later, Chen Kan said that he could observe some tiny creatures that could not be observed with the human eye with a microscope, so his suspicion turned into a doubt.

But the microscope couldn't be built for a long time, and he was running out of patience now.

The weather was very hot, Chen Kan didn't want to speak, and Zhu Zhanji lost his interest in talking.

Soon, Hua Shi came to the gazebo with a basket of fruits.

There is an old well in the backyard of the Hou Mansion, and the water quality is cool.

And these fruits were all put in by Yun Cheng when he got up in the morning.

Among them is the watermelon grown by the Hou Mansion this year.

That's right, Chen Kan finally planted the watermelon, and planted it on the dry plateau twenty miles west of the Hou Mansion.

Facts have proved that watermelons should be planted on the dry plateau, and the watermelons planted in the fertile fields have more water and are not sweet.

The watermelon that grows on the plateau has few seeds, a crispy taste, and more importantly, a high sweetness.

There are three watermelons in the basket and three people in the pavilion, so there is no need to cut them, dig a hole in the watermelon with a silver spoon, and then dig and eat it with a spoon, which is the correct way to open the watermelon.

The three of them held a watermelon the size of a human head and ate it sweetly.

Zhu Zhanyan, who came in the end, saw that there was no watermelon to eat, so he had to pick up the golden apricots, peaches and other fruits in the basket with a resentful face.

"Don't waste food."

Chen Kan slammed a shudder on his head, and Zhu Zhanyan could only cry and eat all the fruits he had bitten.

"Hiccup~"

After eating the watermelon, Chen Kan hiccuped.

Then he looked at Zhu Zhanyan: "Next, let your two senior brothers teach you, for the teacher, you want to go back to sleep......"

Then he got up and wanted to leave.

"Hou Ye, Hou Ye, there is a person from outside, claiming to be the envoy of North Korea......"

Suddenly, Yun Cheng's voice clearly reached the ears of the four masters and apprentices in the pavilion.

There was a curious look in the eyes of several people at the same time.

"An envoy of North Korea?"

Chen Kan asked rhetorically, and when he saw Yun Cheng panting, he couldn't help but subconsciously ask, "Did you bring a gift?" ”

"Huh?"

Yun Cheng raised his head blankly.

Chen Kan frowned, and asked in an accentuated tone: "I said, what kind of North Korean envoy came to see Benhou and prepared a gift?" ”

Yun Cheng looked thoughtful, and then shook his head: "I didn't see that envoy bring any gifts, but it looks like a begging for food." ”

"I didn't bring a gift, that's gone!"

Just kidding, if someone comes and says that he is an envoy of some country who wants to see him, then he will not be busy to death for a day.

What's more, an envoy from a country comes to the door and doesn't even bring a gift, who knows if it's a fake or not.

Yun Cheng was stunned for a moment, and then the corners of his mouth twitched: "Yes, yes, the old slave went to send him away." ”

Zhu Zhanji looked at Chen Kan curiously: "Teacher, what if that person is really a North Korean envoy?" ”

Chen Kan grinned: "Who doesn't bring an entourage when he goes out, and doesn't bring gifts when he visits others, and don't you hear Yun Cheng's words clearly, he looks like a begging for food, which envoy will be so poor that he asks for food?" ”

"Not unreasonable."

Zhu Zhanji, Hua Shi and Zhu Zhan nodded at the same time to indicate that they were taught.

Chen Kan yawned: "You study hard, you are really going to sleep as a teacher." ”

But Yun Cheng went and returned again at this time.

"Hou Ye, Hou Ye......"

Chen Kan squinted at him: "What, refuse to leave?" ”

Yun Cheng shook his head: "No, Master Hou, that person seems to be a real envoy of the Korean State, na, there is still a national letter." ”

After Yun Cheng finished speaking, he handed a copy of the fold to Chen Kan.

Seeing the national letter, Chen Kan's face darkened suddenly.

He was considering the possibility of a different butler.

His attitude just now was already obvious, he just didn't want to see any North Korean envoys, but Yun Cheng actually accepted the letter of state directly.

That's right, Chen Kan had long known that the identity of the envoy of the Korean State was true, and that the envoy fell into Yun Cheng's mouth and asked for food was also planned by him.

That's why he had that attitude just now.

This Yuncheng is really, really more than enough to succeed.

The national letter has been received, and now Chen Kan can't think of it.

With a dark face, he took the national credential from Yun Cheng's hand, and Chen Kan said angrily: "Take him to the side hall and wait!" ”
