The alliance between the Great Jin and Persia triggered a series of chain reactions, first of all, Shile formed a new military alliance with Tuoba Pugen and Eastern Rome, and their purpose was to oppose the Great Jin and Persia.

After the Great Jin Dynasty and Persia re-aligned, the whole world situation presented a strange state, and a confrontation between the two major forces was also formed, with Rome in the Middle East, the Western Regions (the Qiang Nationality), and Mobei on one side, and the Great Jin Dynasty and Persia on the other. The two major forces were hostile to each other and actively prepared for war.

Although the Great Jin Dynasty was about to face a siege from the two major forces in the north and the west, the Great Jin Dynasty, including Sima Shu, did not take Shile and Tuoba Pugen seriously. In fact, it was the Persians who were most in danger, and they had to endure the siege of the two great powers, the East and the West, and among them were their enemies, the Romans.

In addition, Shile and Tuoba Pugen also did not have the confidence to defeat the powerful Jin Empire. The super-empire established by Sima Shu brought great pressure to the surrounding countries, and this pressure was especially felt by the Xianbei people on the grasslands north of the Great Wall and the Qians hiding in the Western Regions.

In the face of the powerful deterrent brought by the Great Jin Dynasty, could it be that Shi Le and Tuoba Pugen were really willing to crawl at the feet of the Han people to survive? Of course not. Shi Le worked so hard to open up the Western Regions, and Tuoba Pugen persistently attacked the weak grassland peoples around him, so that they could accumulate enough strength before the Great Jin attack, and even be able to counterattack the Central Plains one day in the future.

Although the Xianbei people and the Xian people are inferior to the Central Plains civilization in terms of civilization, they are not stupid, and they can clearly know it by looking at the process of their dominance outside the territory. The Xianbei people and the Xian people are not stupid, but they are also an extremely intelligent and even cunning people.

Whether it was Shile or Tuoba Pugen, they knew very well the energy that could burst out of unified China, and the Jin people had beaten millions of grassland aliens to the ground alone. Therefore, in the face of the aggressiveness shown by the Great Jin, the two of them could only unite together.

In the thirteenth year of Hongwu, April and May of 313 A.D. was a period of gunsmoke-filled days, during this period, the East and the West were lit up by war, the world trembled in the flames of war, the world's three major powers and four major forces were all involved in the war without exception, and some powerful countries took the initiative to choose war. Some powerful countries are passively facing war. Some powerful countries were directly involved in the war.

At this time, the world situation was very exciting for the Chinese strategists, because they had not faced such a situation since ancient times. Even Sima Shu was trembling and cautious, although he had shouted to his subordinates that "the wolf smoke of the world war has been ignited, and Huaxia is not afraid of any challenge." ”

But in the eyes of some strategic commentators in China. This global conflict, which has almost swept the world, seems difficult to compare with the civil wars of the Chinese dynasties. In the present global armed conflict. There are four different armed groups at the same time:

The first armed group is the emerging armed group in East Asia with the Great Jin as the core, this group is the leader of the Chinese Great Jin Empire, with a large number of subject states. The purpose of the Great Jin Empire in waging war was very straightforward. That is, to seize large areas of land in the Western Regions and Central Asia, and at the same time to seize world hegemony.

In order to protect the interests of their respective nationalities, they had no choice but to wage a arduous all-out war with the powerful Han clique, and the war they waged with the Huaxia clique was a life-and-death war for the living space of the nation.

The third armed group is the Western bloc with the old power of the Roman Empire as the core, and on the surface the Roman Empire has not completely withdrawn from the quagmire of Europe. But Constantine knew very well that the Roman Empire's rule in the West was gradually crumbling, and a large number of barbarians were invading all parts of Western Europe.

The main reason why Constantine joined this gamble was to open up the living space of the Roman Empire in the East, and since the erosion of the situation in Western Europe was inevitable, why not open up new territories to make up for the loss of the empire?

The fourth armed group was the West Asian bloc led by Persia, and the actual controller of the Persian Empire, Psidore, in order to strengthen his prestige and at the same time to monopolize the silk trade, he could not wait to join the war. Although the Persians were the weakest of the four powers, their desire for war was also relatively strong.

The above four international armed groups constitute the main participating groups in this global war, and because of the different purposes for which they are waged. It is only because of the limitations of communication technology, transportation conditions, etc., that this war is not so much a global war as a local war on a global scale.

Except for the Roman Empire and the Great Jin Empire, which did not need to fight on two fronts due to their geographical advantages, the other two sides had to face a two-front war. Although the Great Jin also declared war on the Roman Empire, the likelihood of a direct conflict between them was too low due to the distance between the two sides.

Although the Persians had asked the Great Jin to send some reinforcements, Sima Shu refused on the grounds of long distances and logistical supply difficulties. Obviously, Sima Shu did not want to intervene too early in the war between Persia and the Roman Empire, and it was impossible for Sima Shu to intervene in Europe until Shile and Tuoba Pugen were settled. Moreover, the defeat of both Persia and the Roman Empire was the most desirable scenario for Sima Shu.

For the same reason, Shiler also did not launch a large-scale attack on Persia proper, he simply kept his troops on the border between the two sides. Shile regarded the Jin as his first enemy, and the Persians' main enemies were the Romans, and although Pusedor was not a man of great talent, he was no fool either, and he focused his main efforts on cleaning up the Romans, especially in plotting to recover Syria.

This strange way of fighting greatly impacted the intellectuals in the Great Jin Dynasty, and the former emperor Sima Shu always instilled in them the concept that there is no friendship between countries, only interests, and also aroused the disgust of some traditional scholars. But this world war made the intellectuals in the Great Jin Dynasty feel the naked conflict of interests. Each country only proceeds from its own interests, and does not think about any allies and feelings at all.

"Arhan, is the Great Jin really allied with Persia?" Hormizd III asked with a gloomy face, since he came to the Great Jin, Hormizd III has not given up the plan to compete for the Persian throne, but the honeymoon period between Persia and the Great Jin was at the beginning, and it was impossible for the Great Jin to offend a big trading partner for the sake of a down-and-out prince.

Later, under the persuasion of Emperor Sima Shu, Hormizd III entered the Chang'an Army Officer Academy to study. For the past two years, Hormizd III has been working hard to learn his skills, and when the news of the Persian expulsion of the Jin merchants came, he thought that the Great Jin would support him to return to China and fight for the throne.

Who knows that the Great Jin Dynasty still focuses on the Western Regions, and now it is allied with Persia regardless of its previous suspicions. A world war has broken out, and the major powers of the East and West have formed two different formations to fight each other. Holmizd III's heart, which had been dormant, became hot again, and his greatest hope was to take advantage of this great war to make a comeback.

"Yes, prince, just yesterday Persia and the Great Jin Dynasty formally signed a military alliance agreement to jointly fight against the Western Regions, Mobei and Eastern Rome." Arkhan replied in a dull tone, saying that he was also quite depressed, and he was not happy that the Great Jin had reconciled with Persia in a few days, and it seemed that the face of this great country was indeed faster than turning the book.

Hormizd III frowned, but even then he didn't think of leaving the Great Jin Empire, in his opinion, among the major armed groups, the Great Jin Empire was currently in the best strategic position. The Great Jin did not face the threat of barbarians like the Roman Empire, nor did it have to fight on two fronts, so Hormizd III had great confidence in the Great Jin.

"Prince, are we going to wait?" Arhan asked.

"What if you don't wait? I am afraid that this war involving the Quartet will not end in three or five years, even if the Great Jin Dynasty exterminates the Qian and Xianbei people, I am afraid that it will not be able to support His Highness in a short time. Holmizd III sighed.

"Why is that?" Alhan asked, puzzled.

"Logistics supplies! Logistical supplies will greatly limit the combat effectiveness of the Jin army. Although Prince Ben participated in military studies for a short time, he still had a thorough understanding of the Jin army. The Dajin Xiang Army is an all-firepower unit, and although it has strong combat effectiveness, it has high logistical requirements. ”

"The roads in that place in the Western Regions are not as smooth as those in the interior of the Great Jin Dynasty, and the Great Jin Dynasty cannot provide us with strong support without fully completing the road construction in various parts of the Western Regions. Look at why the Great Jin Dynasty is retreating step by step in the Western Regions now, is it not because the logistics supply can't keep up? Otherwise, how could it be the turn of the Qiang people to take over the entire Western Regions? ”

"Prince, do you say that Dajin will regret it in the future?" Arhan couldn't help but worry about another problem, the more he knew, the more he worried that the Great Jin would abandon them in the future.

"No, at least not anytime soon! His Highness is still very confident in this! Hormizd III replied categorically.

"Why?" Arhan was puzzled.

"This is beyond the reach of the whip, Persia is so far away from the Great Jin that they may need a friendly country as a trading partner, but they are not yet able to conquer it. Conquest of the Western Regions with the current strength of the Great Jin Dynasty is already their limit, and it is probably impossible to conquer farther places without fifty years of development. ”

Hormizd III was right, and the Xiang army finally realized the difficulties of logistical supply. In order to reinforce the Western Regions, the Great Jin Dynasty mobilized more than 100,000 horses to transport supplies and troops to the Western Regions day and night, despite this, the first batch of reinforcements to enter the Western Regions was still a cavalry unit equipped with cold weapons, and a large number of infantry equipped with firearms were still gathered in the Hexi Corridor, and they could not reach the Western Regions smoothly.
