The talks between the two sides did not end until noon, but most of them did not actually speak, but continued to record what was said between the two sides, especially those Tang officials who came with Gao Shilian and Wei Zheng.

After the meeting, Huo Gang, who returned to his household, didn't think much about it, he still had a lot of things here.

And Wei Zheng, who returned to the embassy, was discussing this matter with Gao Shilian, "Brother Gao, I have an idea, I don't know if Brother Gao can agree." Wei Zheng pondered for a moment and said.

"Duke Wei, please speak." Gao Shilian glanced at Wei Zheng a little strangely.

"I want to stay in Dahan for a year, and take a look at the situation of Dahan here, I don't know what you think, brother? Didn't Minister Wu tell us before? This embassy area was built for us, and this Datang embassy is our Datang territory, and he will consult with His Majesty that our Datang and Dahan will each send an ambassador in each other's countries. ”

"That way, we'll be in touch at all times." Wei Zheng said seriously.

Although this era is limited by communication, the role of ambassadors may not be as good as that of later generations, but there are some things that can actually play a great role if they happen, so this ambassador is still effective.

"This ...... Wei Gong, what do you mean by staying here? You still have an important task in Chang'an, even if there is an ambassador stationed there, it shouldn't be you, Duke Wei, and Your Majesty probably won't agree. Gao Shilian was really shocked.

He thought of all kinds of things, but he didn't expect Wei Zheng to stay here.

"When I return to Chang'an, in fact, it is not of much use, I am self-aware of this, I am not as good as you people in various jobs, the only reason why I Wei Zheng can persist is that I am quite a minister and correct His Majesty's mistakes."

"But to be honest, even if I return to Chang'an now, in the next year or two, do you think I still have a chance to correct Your Majesty?" Wei Zheng looked at Gao Shilian and said.

"Why, isn't there?" Gao Shilian was stunned for a moment, he didn't quite understand Wei Zheng's thoughts.

"Senior brother, you forgot, now Your Majesty's ambition is different from before, to be honest, if Your Majesty is just to maintain stability, then there is indeed a need for me, but if Your Majesty is next to show his ambition, then the probability of him making a mistake will be very low."

"Especially now that almost all the families in the entire Tang Dynasty will be on His Majesty's side, there is not much place for me to stop it, since this is the case, I might as well stay here and learn more about Dahan and Huo Gang." Wei Zheng said seriously.

Gao Shilian pondered for a while, he knew that what Wei Zheng said was correct, to be precise, Wei Zheng's current thinking must be different from before, such Wei Zheng Gao Shilian had never seen it before.

Since he was scolded by Du Ruhui, it seems that this has already been the case, no matter what, if he wants to stay, Gao Shilian thought about it, this is a good way, because Wei Zheng is a person, Gao Shilian knows very well, if he has something, he will definitely not hide it, and such a person is sometimes more suitable to act as a diplomatic envoy.

"However, Duke Wei, if your family in Chang'an is not there......" Gao Shilian said helplessly.

"Then it's up to you to take care of it." Wei Zheng spoke directly.

Gao Shilian was stunned for a moment, Wei Zheng would never say this before, but now Wei Zheng said it with a calm face.

Gao Shilian glanced at Wei Zheng seriously, Wei Zheng's expression was very serious at this moment, Gao Shilian could see that he was not joking, but it was precisely because of this that he also knew that Wei Zheng was very serious and very determined.

"Okay, since you have made up your mind, before we come out, Your Majesty also gave us the right to make a temporary decision, but if I return to Chang'an and Your Majesty orders to recall you, it is estimated that you will have to come back." Gao Shilian said helplessly.

"Don't worry, Your Majesty won't, when you return to Chang'an, it's already winter, Your Majesty has a lot of things and strategies to adjust this winter, and it's about to be the New Year, when spring comes, it is estimated that Your Majesty will take Wuyuan and other areas first, and then next year Your Majesty is estimated to march to the 40,000 acres of black land." Wei Zheng thought for a moment and said.

"At this time, we need a stable situation in the west, although we have signed an alliance with Datang, but at this time I can also give Datang a stable logistics situation."

"So it's also the best option for me to stay here."

"Okay, then I'll go back, then trouble Duke Wei for you to stay, and you leave twenty guards and three officials from the envoy corps to assist you here." Gao Shilian thought for a moment and said.

"Yes." Wei Zheng did not object to this, if he stayed here, he really needed someone to assist.

"Then I will propose to Leader Huo Gang to leave as soon as possible." Gao Shilian also nodded.

Now that the decision has been made, there is no hesitation.

The next day, Gao Shilian and Wei Zheng directly told Huo Gang about this request, Huo Gang naturally had no opinion on Wei Zheng's choice to stay, although he had some surprises, but he simply agreed, the embassy was built, although the ambassador came very early, but Huo Gang had expected such a thing.

However, Gao Shilian and they can't leave yet, mainly because the dowry prepared by Huo Gang has not yet been prepared, and it will take about three days to go, and Huo Gang will directly send a part of the transport team to Chang'an.

Because of these transported things, that is, Huo Gang's convoy here can ensure their safety, and when they are handed over to others, Huo Gang is not at ease.

Li Shimin gave such a big gift, Huo Gang's side as a dowry naturally can't be stingy, but these things Huo Gang has already let people do, first of all, the first gift is the Quyuan plow, the Quyuan plow has been improved by the second generation, mainly more in line with the mechanical model, more saving manpower and animal power.

Compared with the previous straight plough, the curved plough itself saves a lot of manpower and animal power, for example, the straight plough used to almost need two oxen to pull the cultivated land, and the curved plough can be easily pulled by only one ox.

And the turning is more flexible, Wang Shan they have done a test, the same land, the straight plough uses two oxen, the curved plough is a cow, the speed of ploughing between the two is actually about the same, and in a day, even the curved plow is faster.

After testing the ploughshare head of the curved plough in the industrial city, the efficiency of the plough has increased by at least 20% after replacing the plowshare, which can be switched left and right and the curvature has been changed to a certain extent.

Such a plough is almost the same as the plough used in the countryside in the eighties and nineties, at least when Huo Gang was a child, his family could plow the land with just one mule. Of course, it is also possible to use two mules, but they are faster and not too wasted.

When Huo Gang was a child, his family only raised a mule, and when he cultivated the land, he borrowed it from his neighbors, and everyone borrowed livestock from each other to use it, and at that time their family planted more than 50 acres of land, and almost all of them were animal power.

From this, it can be seen how fast this Quyuan plow is to improve efficiency, Quyuan plough was originally named Lu Ji plow, but Lu Ji did not agree, so after thinking about it, since he wanted to give a dowry, Huo Gang simply named this plough Changle plow.

Then this kind of pear was also directly registered in the scope of Dahan, and all the firms that operated this kind of plough in Dahan had to pay 5 points of patent fee to the little Lori who was still in Chang'an for every one sold.

Of course, the amount of money is actually not much, because for most people, many of their plows will choose to find someone to build themselves, for the time being, for this kind of situation of finding someone to build and use for themselves, there must be no royalty at all.

Moreover, in order to increase the cultivated land in the early stage, Huo Gang had already given away a large number of them for free, even if this batch was made up, in fact, there was not much before.

As for Datang's side, Huo Gang didn't mind writing a letter to Li Shimin about the patent statement, as for how to implement it, whether Li Shimin was willing to implement it or not, that was Li Shimin's business.

But Huo Gang felt that Li Shimin would execute it, because the patent thing, as long as it is established, is actually a halter for the gate valve family and dig a pit, and when Li Shimin wants to use it, he can dig a pit for the other party at any time.

In addition, the second batch of gifts is a batch of mercury mirrors. These mirrors range in size and size, and many of them are made into different styles of dressing boxes.

In addition, with this thing in the past, there is also a franchise, which is also for Changle, anyway, this is his future daughter-in-law, although she is still a little Lori, but the money given to her, the future is always her own...... Isn't it?

In addition, there are some gadgets, these things are some things that Huo Gang personally gave to Changle.

A whole batch of dowry gifts is not too big, but the number is definitely a lot, as for how to deal with the shares of Changle, it depends on herself, Huo Gang doesn't care.

Anyway, it is impossible for Datang to make glass in a short period of time.

However, Huo Gang sent two sets of books to Changle, one of which is a geography book, but it is not a complete book, but Huo Gang has screened it, and the second set is mathematics.

The reason why he sent her these two copies was that Huo Gang also wanted her to at least become a person with her own thoughts in the future, not like most of these feudal women in ancient times.
