The destruction of northern Greece by the Centaurs was devastating, when the Tang army completed the population loss of more than 60% in northern Xiula, all the medium-sized cities were destroyed, and the fertile fields were burned to the ground, and in just over two months, northern Greece seemed to return to the barbaric era overnight.

In fact, the Tang army did not have the ability to save the people of northern Greece, even if they immediately went north after the capture of Athens, it was too late to stop the Romans who were determined to destroy the war potential of Greece, not to mention that Leon had no intention of doing so from the beginning, and the massacre and destruction of the Romans was exactly what he wanted to see.

The Romans' voluntary departure caused the Don army to stop the pace of war, and the ruined Greece needed time to govern and recover, and their goal was itself to annex Greece.

So a strange scene happened, the Tang army and the Romans were stationed along the inherent border line between Greece and Rome, and they did not offend each other, as if nothing had happened.

The navy was suppressed to the death, and the Romans had no other way but to defend their homeland, and Leon, after several fierce battles, planned to suppress the Romans and strangle the Romans by encroachment.

In order to achieve the suppression of the Romans, Leon began to think about moving the capital, the western capital city of Baghdad is good, but now that he has annexed Asia and Greece, then the western capital is not suitable for the existence of the national capital, and finally in Xingyuan, Leon decided to move the capital to Byzantine Istanbul, so that he can calmly pass through the Eastern European steppe. In order to achieve the goal of encroaching on Europe, and finally strangled Rome in Western Europe.

Regarding Li Ang's decision, Wang Meng, who was in Xijing City, could only agree after knowing it, after all, Xijing City has not been the capital for a long time, and there was no major repair of the palace at the beginning, so it is not difficult to move the capital, but from the perspective of the future plan of the whole country. Moving the capital is also a must. What's more, Byzantium, which was renamed Zhongjing, is indeed a good national capital.

That's it. When the Tang army established a defensive line against the Romans in Greece, the relocation of the capital began, for the Tang State, which was not long after the founding of the country, there were almost no forces in the country that could resist Li Ang. And contributed money and efforts to build Zhongjing into a capital city comparable to Chang'an. However, Wang Meng, who was in charge of supervising the construction, rejected this very tempting suggestion, his mind was not confused, the land of Tang was fundamentally in the 300 million Han people in Daqin, no matter what, Tang was only a vassal prince of Daqin, and he must not do anything arrogant, so as not to cause unnecessary trouble.

When the Don Army ceased military operations. All matters of the Tang State will be given priority to internal affairs. The ruined Greece needed to be governed, and Asia, which had lost a large number of people, was in dire need of replenishment, so it spent the next three years. The Tang State once again asked for nearly 3 million young people from Daqin to enrich the Asian region, and formed a force of 200,000 people, mainly single soldiers, and handed it over to Ran Min for training, preparing to enter the territory inhabited by the original Germanic peoples, and subjugate the only remaining Germanic tribes under the massacre of the Romans, as a new military pressure point on the Romans.

In the past three years, Cao Ziyun did not have nothing to do in Longcheng as the officials in the Chang'an court thought, but experienced a lot of things with Li Jingqi, they first participated in the construction of the Tang Army's offensive and defensive defense line in Greece, and then went to Wang Meng's side and supervised the construction of Zhongjing City for half a year, during which the two had commanded tens of thousands of construction teams, so after a year, the two entered Europe with Ran Min, Conquered the remaining 100,000 Germanic people and other scattered European barbarians of nearly 200,000 people under the butcher's knife of the Romans, and successfully controlled what was considered barbaric in the eyes of the Romans.

After returning from Europe, the two were sent to Egypt by Leon to follow the Tang army in Egypt to exterminate the bandits, and included Egypt in the territory of the Tang State and became an Egyptian province.

Although the Tang State did not launch an attack on the Romans, the swallowing of the surrounding areas of Rome in the past three years made Constantine and Julius feel like they were on their backs, and they knew that the Tang State was suppressing them to the death on the European continent and dragging them down through military pressure.

Although he knew Li Ang's intentions, Constantine had no choice, his army was at an absolute disadvantage to the Tang army in the field, and if he wanted to fight back, it would be tantamount to attacking the enemy's strength with his own shortcomings. And his navy was suppressed by the combined fleet of Tang and Great Qin, which made him lose the possibility of attacking the Tang mainland, as for the border area of Greece, the Tang army built a more solid defense system, and the Germanic homeland that was subdued by the Tang State was dominated by the plains, and the Tang State rode on

In order to exert all their strength, in such a situation, even the monarch was powerless to launch an attack, and could only watch as Leon formed a strategic encirclement of him.

For the Romans, the only thing they could count on, apart from themselves, may only be the Xiongnu as an ally, but the Xiongnu did not have a good time, and the Great Qin Army, which had restored its former iron-blooded domineering army, restrained the Xiongnu army on the Eurasian steppe, and the huge national strength of the Great Qin was enough to support them in a long-term war until the Huns were defeated. Therefore, the Huns could give the help to the Romans, and only the only thing left was to provide horses for the Romans to train a cavalry force that could compete with the cavalry of the Tang Kingdom, but as Ran Min entered Eastern Europe and subdued the local Germanic and barbarian tribes, the horse trade between the Romans and the Huns was also seriously threatened, forcing Constantine and Julius to redeploy heavy troops on the Western Front to prevent the sudden attack of Ran Min's department.

The pattern of the world is quietly changing under such circumstances, the two Han civilization countries of Great Qin and Tang have suppressed the two most powerful and last enemies of Han civilization in the world in the east and west, and it may only take a few decades for them to completely eliminate the Xiongnu and Romans, and truly realize the great harmony of Han civilization.

Due to the continuous immigration of Daqin itself, the problems caused by the original population increase have been fundamentally solved, because the Tang State has extremely high requirements for the number of immigrants of the native Han people, rather than a little population. Although a significant proportion of the displaced population is forced, it does not hinder the benefits of the overall migration.

The movement of population drove the economy of the Tang State, and at the same time, the process of Sinicization of the Tang State became faster, and the young and strong Han people were continuously imported into the vast area from Central Asia to the Mediterranean, and they often married several women of different nationalities as wives to balance the number of unmarried women in the local area. In the years of war, because of a series of wars and headhunting orders launched by Li Ang and the ethnic vendetta provoked, a large number of male populations in Central Asia, West Asia, Asia Minor, North Africa, and parts of Europe died, according to the secret archives of the Tang State Household Department, the number of men who died directly or indirectly in these areas was about 15 million, which is quite a terrible number, and if there were no Han immigrants from Daqin itself, it would take at least 50 years for these areas to recover.

But now, all problems do not exist, because there is the existence of Great Qin behind the Tang State, and as for the issue of taxation, the officials of the Tang State do not need to worry, the trade brought by the Silk Road is enough to support the national government expenditure of the Tang State, not to mention that they also have the financial support of Great Qin.

For Chang'an, the major families fully support the Tang State, in fact, it is also for the interests of the local area, after all, the Tang State originated from the Great Qin, and now the forces of the Tang Dynasty have also penetrated into it, I believe that it will not be long before the perfect balance like the Great Qin Dynasty will be achieved, in the family alliance in essence, the Great Qin royal family is also the family under this interest group, the Great Qin and the Tang Kingdom will annex other countries in the world, and will create an unprecedented rule of the world.

On the surface, the relationship between Great Qin and Tang is subordinate, but in fact, the two countries are actually a whole, of course, this is Li Ang sacrificed a certain amount of royal power in exchange, he can refuse the family alliance to the interests of the Tang State, but in that case, he will lose the support of Great Qin, and this is not what Li Ang wants, in addition, he himself is not a person with a strong desire for power, what he pursues is like the monarchs of Great Qin, in the long-term stability and balance of power of the country, he has no intention of being a dictator like Emperor Wu of Han.

In the past three years, for the family alliance, one of the things they have done the most is to marry, they entered the Tang court, although Li Ang did not have any reaction, but it does not mean that his subordinates will have no opinions, for these family masters who have been immersed in power for many years, confrontation is a meaningless act, and it is a wise and far-sighted choice to pull these upstarts of the Tang Kingdom into their camp, so it can be said that it is a profitable and loss-making deal to let the daughters of their families marry these upstarts of the Tang Kingdom.

For the marriage, Li Ang is happy to see it come to fruition, those families in Chang'an are well versed in politics, and for the Tang Kingdom, their entry is not a bad thing. What's more, he himself has two marriages with the Great Qin royal family, his eldest son, the future king of the Tang Kingdom, will marry the princess of Great Qin, and his daughter will marry the crown prince of Great Qin, the future emperor Cao Yu Cao Ziyun's real name, for the two countries, these two marriages will make the connection between the two countries even closer.
