"This is the potato?" Dai Xuan looked at the big lump with mud on his hands.

This is Li Yuanji and Li Jiancheng personally escorted dozens of carts of potatoes to Sinong Temple, and Dai Zhou is also the first time to see the true face of this miraculous crop.

And how these dozens of carts of crops suddenly appeared in Chang'an City, it is unknown.

Because even the coachman who pulled the cart was a person who rode in Xuanjia, as long as they didn't say it, no one dared to inquire, and Hou Junji, the secretary of the military department, didn't dare either.

"That's right, you all know the breeding method, for fear that you will make a mistake, this Wang and Zhou will follow and guide you."

The Wang family and the Zhou family brought by Li Jiancheng were the two people who were guarding the seedlings in Shanghe Village.

This will stand behind Li Yuanji tremblingly, the two of them are rural village women, and they have no knowledge.

I didn't expect to be invited to Chang'an this time to teach you how to grow potatoes.

You must know that there are either officials or officials below this Sinong Temple, and for small people like them, they are really adults.

However, Li Jiancheng said that it was really true, the two came here to teach them breeding, but they were paid, and the wages were not low.

Every day, it is also delivered by car, and there are two Xuanjia knights by him at any time to prevent someone in Sinong Temple from asking questions that should not be asked.

At first, the two of them still cowered, but soon let go, because they found that these adults were too polite, and they didn't know if they had been beaten, and their speech could no longer be described as soft-spoken, and it was not an exaggeration to say that they were low-voiced.

So they tried their best to give advice, and they couldn't help but sigh at the power of their own owners.

They wouldn't really be stupid enough to think that these adults were so polite to them for no reason, and they only thought it was because of the owner behind them.

The breeding of potatoes is not too troublesome, under the guidance of the two, but in a few days, the seedlings of these 50 tons of potatoes have basically been completed.

Then it was arranged and distributed by Dai Xuan, and Tang Ping naturally didn't have to worry about these things.

Then there was good news on the side of Dongyue, the conditions put forward by Datang were something they couldn't refuse at all, and the only point of disagreement between the two sides was how much iron for how many ducks.

In the end, Datang increased its troops by 50,000 on the Tang-Vietnamese border, and put on a posture that if you don't give it to me, I will rob it, so that Dongyue successfully compromised.

And in their opinion, no matter how they change it, they will make money, and the duck will be able to hatch a batch of ducks in China immediately.

The iron ore is a little less dug up.

At this time, the entire Datang still adopted a policy of secrecy for the upcoming locust plague.

The main reason for keeping it secret is that it is afraid of causing social panic and that some people will take the opportunity to hoard and raise prices.

At the same time, the Datang government began to send Doulu to contact the surrounding countries frequently, preparing to use the existing resources of Datang to continuously purchase grain to supplement the local government treasury.

"This is Chang'an City!"

A young man dressed as a minority stood outside the city of Chang'an in the Tang Dynasty, he was the prince of the Miao barbarians in the southeast of the Tang Dynasty, and there was a Central Plains named Li Caichen.

This time, he came to Datang with an envoy group to trade with Datang.

Miao Man is in the southeast of Datang, and Dongyue is in the south of Datang, which means that the north of Miao Man is Dongyue Kingdom.

And Dongyue Kingdom traded a lot of iron ore from Datang this time, which is not good news for them.

But fortunately, Datang quickly released the news, hoping to trade with Miao Man.

So he brought people to Datang, and among their group, there was also a blonde, blue-eyed, tall man, who was his teacher Franji.

This Frangi has the title of national teacher in Miaoman, and it is said that he came from the other side of the distant sea, and then brought a lot of magical things.

The recent development of Miao Man is inseparable from what he brought, so his status in Miao Man is very high, and King Miao Man even directly let his son worship him as a teacher.

And Franji will see the majestic Chang'an City is also a little distracted, no wonder they all say that this is the largest city in the Central Plains.

"Let's go, let's go inside!" Li Caichen waved his hand and walked into Chang'an with the mission, but what he thought in his heart was that one day, they Miao Man would plant the royal flag at the head of this Chang'an city.

Datang still attaches great importance to Li Caichen's arrival.

Although they are located in the wilderness of Lingnan, the climate there is warm and sunny.

This also makes the land of Miao Barbarian even the grain twice a year.

What Li Caichen didn't know was that he was planning to enter Chang'an, and the first circle that Li Shimin drew on the globe was also in Miaoman.

That night, Li Shimin hosted a banquet to entertain Li Caichen and his party.

"This time, I actually really want to thank His Majesty Tang Guo."

After three rounds of drinking, Li Caichen said with a smile.

"Oh, where do you start?" Li Shimin asked curiously.

"It's just because of my Miao Man's land and multiple farming, and the Tang plough and keel waterwheel promoted by His Majesty are really agricultural artifacts, and the Miao Barbarian people have benefited a lot!"

Although Li Caichen said these words with a smile, many Tang Dynasty generals began to scold MMP in their hearts!

On the surface, although it seems to be grateful, there is a hidden meaning in the words that ridicule the Tang Dynasty for not being secret, and passing on such agricultural tools to enhance the national strength of Miao Man.

"Hahahaha!" Li Shimin seemed to be unconscious, and laughed a few times and said, "You're welcome, where are the people...... Isn't it a people? ”

The meaning of this sentence is quite intriguing.

At least Li Jiancheng seems that his second brother is telling the other party that your people will also be my people in the future, and there is nothing wrong with living a better life now.

I don't know if Li Caichen understood, but with a wave of his hand, a person walked to the middle with a box in his hand.

"I came in a hurry this time, I only had time to prepare a small gift, and I hope that Your Majesty Haihan!"

Although Li Caichen said that it was a thin courtesy, Tang Chen who was present understood that most of them would not be like this.

This Miao Man Prince reveals a kind of arrogance everywhere, how can he really take a "thin gift"?

Li Shimin nodded, and an attendant went down to take the box from Li Caichen's people, and then carefully placed it on top of Li Shimin's case.

"It's ......"

"This is a dragonfly eye glass bead!" Li Caichen said proudly: "It is fired by the craftsmen of this clan with a secret method, which means auspiciousness!" ”

"Although it's not a valuable item, it's still rare to see outside of my Miao Man!"

This thing, in fact, is a primitive artificial glass product, which was first brought to China by some nomads during the Han Dynasty.

However, after the Wuhu Rebellion, the trade routes were cut off, and this thing was basically very rare in the Central Plains.

And what Li Caichen sent was re-fired by their Miao Man's craftsmen under the guidance of Franji.

Li Shimin said lightly: "So I thanked the prince, I don't know if the prince can ask for something?" ”

"I don't dare to ask for anything, but I have long heard that there are many skilled craftsmen ......in the Tang Dynasty," Li Caichen raised his head and smiled: "I am also most interested in these delicate things." ”
