The process of the Tang Dynasty's annexation to South Asia was smoother than planned, but what Li Shimin wanted was always long-term rule, so taking over power was only the beginning, and the follow-up construction, economic development, and stability of all the people were more important.

After all, these are areas that have been ruled by religious regimes for a long time, and it will take a long time to completely change their cultural traditions.

In late October, all parts of the Tang Dynasty held all kinds of grand celebrations for the victory in South Asia, and a new batch of students who had obtained state-level diplomas, numbering tens of thousands, will rush to South Asia under the leadership of some veteran officials with experience in administration to take up the posts of administrative officials in various prefectures and counties.

This time it may be three years and five years, but they do not have the sadness of parting, on the contrary, they are all high-spirited and want to make some achievements and return to their hometown.

Heraclius in Constantinople was not so happy, in history, he was assassinated by others and died, perhaps because he did not die, so that the defeat of the Byzantine Empire was delayed for more than two years.

After all, visiting Datang many times gave him a broader vision than his father Flavis, and learned a lot of more advanced political and military management methods from Datang, and purchased more materials that could be used for military equipment, although these behaviors made him owe tens of millions of debts.

Therefore, after desperately stabilizing the defensive line, he had no choice, so he could only borrow money from Datang again.

If it weren't for this defeat at the front, he would have even seen the hope of his country's resurgence.

Because, those fields planted by the people led by the Tang agricultural students have achieved bumper harvests, and the corn cobs are full of corn, heavy ears of rice, ears of wheat, and even the whole crop can be bent, and it will not take long for his granary to be filled with these grains.

And the people who have learned these farming techniques of the Tang Dynasty will bring him endless this kind of war capital, just like the Tang Empire, they never consider how much it costs to build a pair of iron armor, never consider how much food a warrior needs to eat, how much meat, and how much salary he gets.

Therefore, after the decadence, he came to the manor where Sun Xiangfu lived, what he didn't know was that as early as a few days ago, Qu Tuquan had already brought information from all parties and discussed with Sun Xiangfu here for a night.

"Your Majesty Heraclius, you are the emperor of an empire with a population of tens of millions, and you should not be so decadent." In the living room, after Hillac, who had long since lost the charm he had a few months ago, sat down and did not speak, Sun Xiangfu, as the temporary owner of this manor, took the lead in opening the topic.

"Is it just a population of 10 million? Our Byzantine Empire was supposed to be the strongest empire in the world, but now, all we can say is that there are only tens of millions of people left. Chirac replied with a little frustration.

In fact, even if most of the area south of the Mediterranean Sea was lost, the land area of the Byzantine Empire was not smaller than that of the Great Eclipse, because at this time, the entire Nordic region belonged to the Byzantine Empire, including Spain, Italy, Britain, France, Germany, and even Denmark, Norway, and Sweden.

It's just that in the current period, the civilization over there is relatively backward, the output is relatively small, and the Byzantine Empire's control over that part is also relatively weak.

But when it comes to fighting, these people are not on the same level as the big cannibals, the big cannibals who grew up on horseback are natural warriors, and their ferocity is even much more than the Turkic people in the north of the original Tang Dynasty, because they have fanatical beliefs, and in history, they defeated the Tang Dynasty in the Tang Dynasty, led by famous generals like Gao Xianzhi.

"There is hope, and besides, I don't think you are a mediocre and incompetent monarch."

As if encouraged by Sun Xiangfu's words, Heracle took a deep breath and cheered up, "I came this time to talk to you about the loan, I know that as the plenipotentiary ambassador of Datang, you have the power to make direct decisions." ”

Sun Xiangfu nodded and said, "That's right, when I arrived in Constantinople on the first day, I told Deacon Ivan that my Majesty the Emperor of the Tang Dynasty wants to see the Byzantine Empire better, so I am willing to provide you with some agricultural technology or other assistance, you can tell me what you need." ”

"We need enough weapons, armor, chariots to defeat the Great Eclipse······" Hearing Sun Xiangfu say this, Heraclius was a little excited and said quickly.

However, when it comes to the back, his voice is getting quieter and quieter, because there are too many things that need to be used as collateral to borrow these things, after all, the cost of military equipment is inherently expensive, and it is impossible for Datang to sell them cheaply.

But who knows, Sun Xiangfu gave him an unexpected answer.

"No problem, these things, as long as you quote the number, my Datang can sell them to you, and the quality and power are even better than you imagined, in addition, I can also provide you with an unsecured loan."

"This ······"

Chirac didn't expect that Sun Xiangfu didn't need to think about it when faced with such a large amount of borrowing, so he agreed, which made him stunned.

And Sun Xiangfu said with a wry smile, "If you had signed an agreement with our Datang to obtain these weapons and equipment when I first arrived in Constantinople, perhaps, you would not have suffered this defeat." ”

Hearing Sun Xiangfu's words, Heraclius suddenly regretted it, but unfortunately, regret was useless, at that time, he and Ivan both did not trust Datang very much, and they remained hesitant about this, and never thought that in just a few months, the situation had changed greatly.

Of course they don't know that the actions of the Great Food Empire, Datang has been well aware of it from the beginning, this world can influence the power pattern of the world, as long as Li Shimin, this whole scene is directed by him.

Therefore, at this time, in the Kermansha area on the border between the Great Food and the Tang Dynasty, the Byzantine Empire people who were captured by the Great Cannibals were being taken over by Hou Junji, and a cart of grain, cloth, and iron equipment was pulled out of the military camp of the Tang Army and transported back to Medina by the Great Cannibals.

"So, what do we have to pay?" After Heracle finished repenting, he looked at Sun Xiangfu with a solemn face and asked.

"It's very simple, hand over the big cannibals you captured in the war later to us Datang to pay off the debt." Sun Xiangfu smiled.

Collecting prisoners in both directions and consuming the war potential of the two countries is the strategic plan formulated by Li Shimin, these manpower, in the hands of Datang, can continue to create all kinds of materials, use materials, and then exchange more manpower, such a cycle will make Datang's national strength in a state of continuous rise.

And the Great Food and Byzantium, which consumed each other and lost the population, obtained the import of materials, so that their war could continue, so that in the war, the materials they got were consumed again, so they will become weaker and weaker, and when they finally can't maintain the situation and collapse, Datang will come out to clean up the mess and unify Eurasia in the most labor-saving way, which can achieve the best effect.

Moreover, during the whole process, Datang was not worried that their war would stop, because the national characteristics of Dashi determined that they could not be self-sufficient, and when the strength of their two sides reached a balance, Datang could easily break their balance by aiding one side.

For example, now, Heraclius was eliminated by the Tang Dynasty in the early years, and it is a pity that the military equipment that is not used and cannot be used is likely to make a turnaround and regain the lost territory, and when the big cannibal can't withstand it, Sun Xiangfu almost came back from the Byzantine Empire and sent the big food.

Soon, Heraclius signed an agreement with Sun Xiangfu, and, only half a month after the agreement was signed, Datang sent him 20,000 bed ballistas, 20,000 ballista cars, 50,000 catapults, 200,000 pairs of iron armor, 100,000 pairs of horse Kai, 200,000 war horses, stainless iron steel knives, spears, 500,000 handles, 20 million stones of grain, and many more follow-ups.

Of course, because of these things, the national debt owed by Byzantium to Datang has reached 150 million guan, and the interest alone will be 15 million guan per year, and these money, they can repay it by capturing prisoners from the battlefield, Datang does not distinguish between races, young and old, all of them are purchased at the price of ten guan per person, with the current situation, they have to capture at least half of the big cannibals and hand them over to Datang in order to fill this hole.

The cannibals used the more than 5 million people in the newly occupied area to exchange for 50 million yuan worth of grain, cloth, iron equipment and other materials, military strength and material reserves, and territory in Datang, all of which have grown a lot.

And Heracliu, who borrowed 100 million yuan worth of military equipment in Datang, was also very happy, and with these powerful equipment, he immediately reorganized his arms and battle, intending to regain the losses he suffered in the next war.

Datang is the busiest country, plus nearly 30 million people in South Asia, the total population of Datang has exceeded 110 million.

In this way, time flickered, and in the eighteenth year of Zhenguan, Sun Xiangfu still lectured in the fields around Constantinople every day, and more than 1,000 peasant students and skilled farmers were scattered throughout the Byzantine Empire, following his example, explaining agricultural knowledge to the people and leading them to farm.

In just half a year, Chinese, which was originally only popular among the magnates of the Byzantine Empire, made the local people no longer unfamiliar, and even, many ordinary people, could open their mouths to say a few words.

Since they saw the crops in the field, far exceeding the previous yield, they were more willing to be quiet, listen to these gods from the Tang Dynasty, the language barrier, they will try their best to overcome it, people who can have this kind of magical ability, in their opinion, are gods, gods, gods, they must listen.

Of course, there is also the reason why they already know that these people in Datang who can make the yield of crops more will not stay here forever to teach them farming, so their time is very limited, and they must learn quickly.

To their dismay, Heraclius the Great, seeing that the output in the fields had increased, proposed a tax increase.

So, even if they grow far more than they originally produced, they don't get much more for themselves.

As for the reason for Heraclius' tax, the people of Byzantium can basically understand it, because the empire is suffering from the invasion of the Great Cannibals, and Heraclius the Great needs to recruit more troops to go to the front line to fight the invaders.

Therefore, in order to be able to get more, they have to work harder to farm, so they must work harder to learn farming techniques from the envoys sent by the Tang Dynasty.

If you want to learn, you have to know Chinese! Therefore, the Chinese language academy in Constantinople and its nearby cities is now the most lively place, and the Han culture is rapidly spreading in this region.

And when they came into contact with Han culture, they realized how ignorant the things they originally believed in were.

It turns out that the Tang Dynasty all believe in scientific knowledge and explore and pursue the origin of things, so the faster the Han culture spreads locally, the fewer people who believe in religion, which is the real purpose of Sun Xiangfu's mission.
