From afar, Sun Xiangfu saw a disappointed expression in Heraclius's eyes, obviously, Ivan's conversation with Sun Xiangfu did not get a satisfactory result, but he was still very interested in what Ivan said about military procurement.

It would be perfect if we could purchase a batch of weapons and equipment from the Tang Dynasty, teach the cannibals a hard lesson, and drive them back to the Arabian Peninsula.

For this reason, he can even consider finding a mortgage in the Tang Dynasty, although after the incident of the Persians, he knows that this is a very dangerous thing, but he wants to solve the trouble of the big cannibals, only if they are beaten, they will develop in peace.

"Your Majesty, we don't need to make a decision in a hurry, let's see if the Datang mission really wants to improve our agricultural production, if, according to Ambassador Sun, let us become rich first, and then they will make our money, then this doesn't seem to be a bad thing."

After Ivan came into contact with Sun Xiangfu, he found that his brain was a little insufficient, but he knew one thing very well, that is, so far, the Byzantine Empire did not seem to pay any price.

All the materials and technical knowledge were given by Datang for free, and they were given more favorable conditions, but they were not required to do more than now.

Therefore, he felt that even if the situation changed later, they could adjust it according to the situation, and they would not suffer losses anyway.

He didn't know that what Datang wanted has always been the will of the people, and if the materials are concerned, with the current development model of the Tang Dynasty, there will be as many people as they want, and the people's will is what is beneficial to long-term rule, and it is impossible to talk about governance in these areas that are more seriously affected by the religious regime, without the support of the people.

"Then you can arrange the itinerary of the envoy according to what you have prepared in advance!" Heraclius gave final instructions.

Soon, Sun Xiangfu realized what Heraclius said was prepared in advance.

If, this time the envoy to the Western Regions is a demon in the color, then, he will definitely be able to get unimaginable satisfaction here, take a bath, there are dozens of white-skinned like silk girls to serve the feeling, it is really unprecedented, why talk about their skin!

Because, they didn't wear clothes at all, and it was no wonder that Sun Erli's kid fell in love with the taste of orchids after he went to the Western Regions back then.

It's a pity that Li Xiangdie and Yao Hongsleeve, the two who protect food, seem to have been on guard against this, these orchid girls can basically only do some chores such as serving towels, pouring wine, and peeling fruits by the bath.

"You two, you don't have to be like this, I've always known restraint as a husband, and I want to live a few more years!" finally persuaded Li Xiangdie, who was sitting on his body and constantly writhing, to persuade him, and Sun Xiangfu put aside the hands they were pulling on him.

"Who knows if what the husband said is true, the concubine feels that it is more realistic to make you feel powerless." After Li Xiangdie finished speaking, she stretched out her tongue very temptingly and crossed it on her lips, and then, the whole person dived into the pool, Sun Xiangfu knew that she was going to perform her unique skills again, and she wanted to open her mouth to stop it, but her mouth was blocked by Yao Hongsleeve's fragrant lips.

After a while, Sun Xiangfu, who was paralyzed and limp and didn't want to move on the edge of the pool, realized how the Byzantine Empire resolutely implemented monogamy.

In such an open social atmosphere, if there is polygamy, it is estimated that men will not live long.

After resting for two days in the manor arranged by Heraclius, Sun Xiangfu was finally able to start doing business, Li Xiangdie and Yao Hongsleeve also had their own tasks, leading the actors of the art troupe to tour in the Byzantine Empire.

The teaching place arranged by Ivan for Sun Xiangfu is a church with a grander building than the royal palace of Heraclius, called St. Stephen's Church, which is the church where Heraclius and his father Flavis got married, and is the holiest place in Constantinople during this period.

These religious regimes always like to put good things in relation to the church, and Sun Xiangfu had no choice but to be as entertained as the Lord wanted.

With the level of Byzantine architecture earlier, even the grandest St. Stephen's Church could only accommodate two or three thousand people at a time, and when Sun Xiangfu walked up from the corridor to the podium, which usually only bishops can stand, he saw the "Sun's Agricultural Codex" in the hands of those who attended.

There were even many people who were holding two books, one of which had been translated into Byzantine script, and there were many purple-clothed nobles, and there was a young man squatting next to their seats, which should have acted as their translator. And the people present were basically the aristocratic class wearing decent clothes.

After standing on the podium, Sun Xiangfu first showed a smile of Hexi, and then said aloud, "Everyone, in the next class, in fact, you don't need to bring that thick agricultural book, because the knowledge above is too profound, in a short period of time, you can't understand, and I can't teach it, you can bring a blank notebook, and a quill pen to make some records of what I said." ”

Sun Xiangfu's opening remarks made all the Byzantine nobles who were mentally prepared to learn the most profound agricultural techniques of the Tang Dynasty in an uproar.

However, this is just an opening remark, Sun Xiangfu then said, "Agricultural knowledge, in the initial stage, is to teach everyone how to plant a good field, so, after doing some basic explanations, we also have to bring farm tools, go to the field, on-site explanation, demonstration, you should be ready!" ”

After he finished speaking, the nobles on the scene couldn't be quiet.

The nobles of Byzantium are basically the same as the nobles of the Tang Dynasty earlier, living a pampered life, how can they personally go to the fields to farm!

Seeing that they thought that the knowledge of agricultural science was a kind of magic that could make crops grow more lushly, Sun Xiangfu was relieved, what he wanted to teach was not these noble lords of Byzantium at all, but ordinary commoners.

That is the group with the largest base in Byzantium and the most representative of public opinion, and that is the group that can provide productivity and create value for Datang in the future.

Therefore, this class started relatively quickly and ended quickly, and Ivan, who was present to listen to the class, quickly knew what the problem was, and immediately began to adjust after the class.

The climate near Constantinople during this period is actually similar to the Lingnan coast, even in the coldest time of winter, the average temperature throughout the day is above eight degrees, most of the time, the temperature during the day is generally more than ten degrees, and it is suitable for planting crops all year round.

Within a few days after Ivan replaced the people who attended the lecture with peasants who actually cultivated the fields, Sun Xiangfu began a large-scale field training in the fields around Constantinople with agricultural students and Byzantines who could understand simple Chinese.

In the past few years, all kinds of agricultural tools in Datang have begun to flow here, and under Ivan's deployment, all agricultural students can basically use relatively standard and efficient agricultural tools in the places where they teach.

Then, the Byzantine farmers knew that before sowing, there was a lot of work to be done in the field, draining fertilizer, plowing the field, lime to remove soil pests, applying base fertilizer, raking the field and breaking the soil, drying the field, making a nursery bowl to cultivate seedlings, transplanting seedlings, fertilizing water, etc., just a simple corn planting, than they originally sown directly, I don't know how many times more complicated, not to mention some other cotton, melon and other crops, as well as later manual pesticide, pollination and other work.

It is no wonder that Datang's corn has a production capacity of 1,000 catties per mu, while their Byzantine corn has a yield of only 400 catties per mu.

In September, when Sun Xiangfu led the agricultural students and skilled farmers in the area near Constantinople, the fields planted were growing crops that were about to bloom and bloom, Ivan entered the palace again and reported to Heraclius.

"Your Majesty, the people of the Tang Dynasty Envoys, except for the singing and dancing performance team that is walking around, performing programs for the people, and distributing gifts, the teams of other professions have reached some cooperation agreements with us.

They will open hospitals, Chinese language schools, factories, and shops in the main cities of Constantinople and several other regions, and these establishments, in addition to using some of their men, will also recruit a large number of our people as helpers and apprentices, and pay taxes to the empire according to the tax standards set by the empire. ”

When Chirac heard this, he didn't say anything, his eyes looked ahead very empty, and handed Ivan a battle report that had just been sent from the front line, but it wasn't because he didn't pay attention to the envoys of the Tang Dynasty.

It is because, as the emperor of a large empire, he has many more important things to pay attention to, this empire, but this empire has a population of more than 40 million, more than 2,000 cities, five large military regions, more than a million troops, and a national border that needs to be guarded, so his daily affairs are very busy, especially when there are wars and conflicts on the border.

The content of the war report made Ivan's whole body tremble, this was the largest defeat in the history of the Byzantine Empire's war with the Great Eclipse.

The army of the Great Cannibals, marching in all directions, captured Balastan, Syria, Damascus, Jordan, Egypt, Jerusalem and other regions that originally belonged to the Byzantine Empire.

As a result, among the five major military districts of Byzantium, the two most powerful military districts and placed at the forefront of the two military districts, all the sergeants were wiped out, which was almost equivalent to their land and military strength, which was reduced by half.

After such a great defeat, the whole pattern changed, and Byzantium could only become a country that was constantly shrinking and struggling under the blows of the Arabs, as it was in history.

And when Heraclius received this battle report from the front, in the distant South Asian region, Liu Hongji finally led the army of Tan Mo Dao and took over the defense and politics of Qunu City, and as early as more than two months before, the lands of Jialou and Bi have also been included in the Tang Dynasty.

At this point, all the land in the entire South Asian region is owned by the Tang Dynasty, and the Eurasian continent has also formed a three-legged trend, with the Tang Dynasty accounting for two-thirds of the area, and Dashi and Byzantium occupying the remaining one-third of the area, and the number of people is almost the same proportion.
