After the fourteenth year of the Imperial Conference, due to the communication of the Ministry of Foreign Affairs, the countries of Taixi have gradually settled down, so these countries invariably began to send envoys to Chang'an to pay tribute, especially after the opening of the Phoenician Canal, the warships of the Tang Dynasty began to enter the Mediterranean Sea in a steady stream, and the ironclad warships and ironships from the Tang Dynasty made all the Taixi people feel the powerful power from the East for the first time. Wang Shoutian's Ministry of Foreign Affairs even temporarily set up a branch in Egypt to deal with foreign affairs from the Taixi countries and the Tang Dynasty.

And just when these envoys continued to board the ship from Taixi to Datang, the successful return of the Ocean 1, and the internal crew returned to China from east to west after traveling tens of thousands of kilometers with great difficulty, and even when Li Xuanqing met everyone in Chang'an, many people still felt like a dream. But they proved one thing to everyone with their feat of non-stop sailing, that is, the earth in the "round heaven" that everyone has known from ancient times to the present day is now round. Subsequently, Li Xuanqing directly painted all the areas that have been explored on an elliptical sphere and named it "Earth", and the most important geographical knowledge was completely reversed at this moment, and modern geographical science finally became regular. After the voyage details of Ocean 1 were all published in the Imperial Weekly, a large number of weekly magazines were sold out for a while, and countless students and scholars began to think deeply about the problems in the face of this change, and in the following years, after a large number of new ships were promoted, they continued to explore new areas, and gradually filled in the "earth" that Li Xuanqing had announced.

After the natural sciences were promoted from the modern geographical sciences and other disciplines were truly systematized and professionalized, Li Xuanqing and Qiaoxi finally put down their last thoughts, and the empire they had created had a long-lasting foundation. After destroying all external threats, the people of the empire finally let go of the shackles of self-righteousness and began to find hope for continued breakthroughs in scientific exploration and research. Therefore, after the fourteenth year of the Apocalypse, both the natural sciences and the humanities began to enter a period of rapid development. Thanks to the practical needs of industrial development has entered the vigorous progress, after several sublimations of practical science, the Chinese people's understanding of the discipline began to theorize, and strive to unify the fragmented practical knowledge between various disciplines in the theoretical category, so as to find a consistent theoretical basis in it, which can be regarded as Li Xuanqing's tireless traction for so long has played a great role.

The lively and lively World Congress in Chang'an City came to an end at the Chang'an Empire Building in the new city, and the cabinet members headed by Zhang Jianzhong collectively attended the meeting, signed a series of conventions with representatives of various countries, established a new order in the diplomacy of various countries headed by the Tang Dynasty, and also implemented the three basic principles promulgated by Li Xuanqing. At the end of the meeting, Li Xuanqing and Qiaoxi also attended the closing ceremony, and when Li Xuanqing took the stage to speak at the Chang'an Conference, which was attended by more than 50 representatives of large and small countries, everyone expressed their most sincere respect for the emperor and empress of the Celestial Empire, who were in the prime of their thirties. It was His Majesty the Emperor in front of him who brought this ancient Eastern Empire to the height of today's world-watching, and could calmly overlook the great power demeanor of all countries, and the true mind and strength of the Celestial Empire.

When the excitement dissipated, Chang'an City seemed to have undergone a great change, overnight to see so many countries envoys to Chang'an pilgrimage, the pride of the past that all countries to come to the dynasty seems to have returned to this ancient capital. Almost overnight, all the people of Chang'an had a kind of self-confidence and could calmly face everyone's sprinkling. In order to cope with the rapid development of Chang'an City, Guanzhong Province has invested a lot of manpower and financial resources to renovate the new urban area, and has re-refined the previous traffic laws and regulations to establish a complete set of strict travel rules to cope with the travel problems brought about by the sudden increase in population.

In September of the 14th year of the weather, after several years of fierce fighting, the Western Expeditionary Army, which set out from Hexi and fought all the way to the Mediterranean Asia Minor Peninsula thousands of miles away, finally began to return to the court, and under the overwhelming propaganda of the Imperial Propaganda Department and the media group, this heroic army received the attention of the whole country, and on the way home, countless people spontaneously sent blessings to all the troops in the cities along the way. In addition to laying down a vast territory in the past few years, the Western Expeditionary Army used tens of thousands of miles of territory from east to west, and also helped the construction and stability of the Northwest when the Northwest Garrison Army was stationed. Moreover, the northwest base of the logistics department has also drawn out a lot of manpower and material resources, and every winter, it goes into the people to help the people in need. Therefore, as soon as they heard that these troops were going to return to the country, the people who had benefited from them came almost day and night with their most precious gifts to bid farewell to their former benefactors. This once pushed the originally set return plan back again and again, and even Wan Yi and other high-level officials of the Western Expeditionary Army were at a loss in the face of the surging people. However, fortunately, the order of the general staff did not allow all the troops to return at one time, so these people did not follow the train all the way to the Central Plains.

Because the generals from the northwest of Hammud and Zhang Sheng had to return after going to Chang'an to meet Li Xuanqing, the General Staff divided the Northwest Military Region into three, the original Northwest Military Region governed the old land of Anxi, and on this basis, the new Mediterranean Military Region, headquartered in Egypt, and the Marine Corps jointly officed, with Zhang Sheng's Anxi Corps as the garrison, and the Persian Military Region was the headquarters of the Marine Corps in the West. Li Guixin, the original general of the Wolong Port garrison, took over, and the Central Asian Military Region, which penetrated deep into Asia Minor, continued to be garrisoned by the Uighur Corps led by Hammud. In this way, after the redistribution of the defense of the northwest region, the three military regions have retained their basic combat strength and can cope with basic emergencies, and the northwest of the Tang Dynasty has ushered in a period of peaceful development. Due to its proximity to the Tessie, the local economy began to recover and develop after being militarily secured. In particular, the newly established province of Egypt, because of the increase in exchanges between the Tang Dynasty and the Taixi countries, has become a veritable golden waterway, and after the division of the Great Food Empire, in addition to the Jewish Kingdom, the other five countries all want to get the share of the shares when they signed the treaty with the Tang Dynasty, so they are inextricably linked. It's just that although Ayabi's Baghdad Caliphate Kingdom claims to be the successor of the former Great Food Empire, it was cut off by the Heavenly Kingdom, so the two sides fought a war of words for several years, and then Amdullah even led the army to fight with the other party, and only with the help of the new naval fleet forcibly repelled the other party's request and signed a renewal contract with the Tang Dynasty. And because of this, the caliphate of Baghdad led by Ayebi quickly emerged from the difficult post-war difficulties and gradually recovered. Moreover, Ayabi's own good relationship with the Tang business community has also attracted more of the Tang Dynasty's share of trade, and although Baghdad cannot continue to recover its former glory, it is obviously much stronger than other countries.

However, no matter how these five countries dispute, they could not shake the status of Datang. After the Taixi countries and the Tang Dynasty signed a treaty, Ayabi also took the lead in responding, saying that Baghdad recognized the Chang'an Convention, and said that Baghdad would continue to pay tribute to the Tang Dynasty, and as a vassal state of the Tang Dynasty, Baghdad was willing to follow the steps of the Tang Dynasty. His move then also caused the other five countries to send envoys to Chang'an, and even the most stubborn Heavenly Kingdom began to change its attitude, and after realizing the gap with the other party after being defeated by Amdullah's army, he also took out a huge amount of wealth to go to Datang to order a large number of weapons and equipment, in an attempt to prepare for a reversal. However, the Heavenly Kingdom itself is only the religious origin of the former Great Food Empire, and even the Pope is responsible for handling the usual government affairs, so even if there is an influx of a large number of new weapons from the Tang Dynasty, the combat power of the army in a short period of time is simply not comparable to the soldiers who survived a hundred battles in the hands of Amdullah. However, this move of the Kingdom of Heaven still made the Jewish kingdom on the Mediterranean coast like a great enemy, because it occupied Jerusalem, so although it was small, it still squeezed out some money to purchase weapons and equipment. Moreover, it was very prescient that the Jewish kingdom did not buy weapons and equipment tightly, but reached a preliminary intention through continuous contact with the Tang Dynasty, and sent a quota of students to study in Chang'an every year. Although Datang has many restrictions in this regard, it still opens a window for the transmission of Datang's advanced knowledge to the outside world, and in the following years, hundreds of young children from all over the world will also spread Datang's knowledge to various places after returning to China after completing their studies.

As Western affairs gradually became the center of the empire's foreign affairs, Egypt became the empire's disposal center on the Mediterranean coast, and even after Li Chengyu decided to reside in Egypt, the Ministry of Foreign Affairs began to shift its focus to the west, and Li Chengyu established the Tang Empire's Taixi Affairs Processing Center in Egypt's Finici City, to facilitate the communication between countries and the Tang Dynasty.

Fifteen years after the Apocalypse, in the last year of Zhang Jianzhong's first term, the Tang Dynasty decided to send a joint fleet led by the military to the new continent newly named "Dongzhou" after a lapse of one year, and establish a base in several areas selected by Li Xuanqing, and this time because it was a joint fleet led by the military, in addition to establishing a base as a long-term existence, a large number of scholars and students of various disciplines also brought back to the Central Plains a variety of products, animals and plants from this land. Although this behavior was later stopped by Li Xuanqing, corn and other specialties that were common in later generations were successfully planted in the Central Plains, and then quickly became popular. Thanks to Li Xuanqing's guidance, this huge land spanning nearly 10,000 kilometers from north to south began to be gradually incorporated into the overseas territory of the Tang Dynasty. As a result, the territory of the Tang Empire was expanded again, and although the empire did not wipe out the local indigenous population, this colony-like occupation still brought great benefits to the Tang Dynasty. After the huge import of gold and silver, the central bank of Datang completely got rid of the embarrassing situation of deflation, and sufficient Tang coins began to supply the market, so that the momentum of the development of industry and commerce, which continued to rise, was once again poured into a basin of hot oil. Driven by various practical needs, science and technology have once again ushered in a climax of development, and under the continuous promotion of Li Xuanqing, the scientific laboratory of the Imperial Family Group in Hokkaido, which has been experimenting for many years, has gradually reached the point of instigating. With the breakthrough in electricity, the radio that Li Xuanqing and Qiaoxi never forgot finally sprouted.

After learning the news, Li Xuanqing immediately rushed to Hokkaido with Qiaoxi in person, and asked Zhang Jianzhong to quickly issue an order to use the entire Hokkaido as the basic test area of the empire, so as to concentrate on the construction of a large number of experimental production areas and laboratories, and merge the high-tech laboratory and the imperial laboratory of the equipment department, let Mu Chen be the head of the high-tech laboratory, and concentrate the most elite group of people in the empire to start studying the latest technology.

After the new technology was settled, Li Xuanqing made a major decision and began to let go of the interrogation of domestic affairs, so that his eldest son Li Tianqi, who had been trained in the army for several years, began to supervise the administration of the country, so that he could familiarize himself with the affairs of the empire in advance. He left Chang'an with Qiaoxi and others, and toured around the empire, on the one hand, to guide industrial development, and on the other hand, he also planned to take Qiaoxi to travel through the vast empire he had defeated.

However, at this time, the Tang Empire has gone out of its own way, although Li Xuanqing does not care about political affairs, but the troika headed by the cabinet, the Tiance Mansion and the Law Court has been completely stabilized, and the internal promotion channel has always been kept open because of more and more strict supervision, and the prosperity brought by the continuous emergence of all kinds of talents has made all kinds of new problems appear in this period, but they have been solved in the end. Although Li Tianqi does not have Li Xuanqing's vision that transcends the times, the style of his father and mother in handling political affairs since he was a child still makes the eldest prince fully supported by all levels of the empire.

"Qiaoxi, even if we return to that era one day, we can be regarded as having an explanation for everyone, right? We changed history, we changed empires, we changed the world. Li Xuanqing stood on the endless sea with Qiaoxi, on the wide deck of the Empire cruise ship, the two whispered, Murong Feixue in the distance was getting closer and closer, Li Xuanqing smiled slightly, this moment seemed to return to the scene when the three of them met for the first time in Fengzhou.
