On the road from Gaoping, the capital of Liangguo, to Chang'an, the western capital of the Han Dynasty. A mighty army was galloping on horseback.

This army was all dressed in Hu costumes, and there were even camels in the ranks, but they strangely carried the horse chopping knives that the Protectors were accustomed to, and each horse was also equipped with a Takahashi saddle and two-foot stirrups, which seemed to be a mixture of the Hu people and the Jin army.

This Hu cavalry army is naturally a mixed Hu and Han army led by the second prince of Yanqi, Long Zhihu, and the fourth prince, Long Milling, and secretly led by Zhao Xing and Ma Chao. After they occupied Gaoping City without any suspense, they rested in the city for two days, and after completing the troops' redress and discipline training, they set off again, all the way through the five cities of Chaona, Pengyang, Linjing, Yinpan, and Quail without entering, and walked along Jingshui, and finally arrived at Zuo Fengyi, who guarded Chang'an.

Zhao Xing, who was hidden in the middle of the army, ordered people to call Ma Chao, Ma Dai, Long Zhihu, Long Milling and others to the front of him, and then said with a serious face: "After Chiyang, Chang'an City, the capital of the Han Dynasty, is already in sight, this city is the place of Chinese civilization and luck, the first of the world capitals, there are more Gaoling, Yangling, Anling, Changling, Baling, Pingling, Maoling, Duling and other imperial tombs, which are the richest and most densely populated places in the world!" In Gaoping City, I have admonished the whole army that after entering the Sili area, you must strictly abide by military discipline, and you will not commit any crime in the autumn, otherwise you will be punished with capital punishment, and you need to remind your generals at all times, you must not knowingly commit crimes, otherwise you will blame me for being ruthless!"

Seeing that Zhao Xing said harshly, the generals knew that this matter must not be sloppy, so they replied in unison: "Carefully follow the teachings of Lord Taifu, once you find a person who violates discipline, you will not be spared!"

Zhao Xing attached so much importance to maintaining military discipline and abiding by the discipline of the masses only because he remembered the tragic records of Li Dao and Guo Yan in the history books who disturbed Chang'an. Even from the Eastern Han Dynasty onwards, Chang'an City is also the world's largest cultural city, ahead of Athens, Rome and Cairo. This city is a symbol of the inheritance and luck of Chinese civilization, once Chang'an falls, there is a chance that nine times out of ten it will be ruined and the dynasty will be changed.

During the Northern and Southern Song Dynasty, Chang'an was occupied by the Western Xia Kingdom, and the Song people were always bullied by the nomadic peoples in the northwest and north; after the outbreak of the War of Resistance Against Japanese Aggression in modern times, most of the land of China fell, and the former capitals of Beijing, Luoyang, Kaifeng, and Nanjing were occupied by the Japanese invaders one after another, but the dirty feet of the little devils never stepped into Xi'an, Guanzhong, so the Chinese civilization still stands.

For Zhao Xing, protecting Chang'an is equivalent to protecting the cultural roots of the Han people, so he repeats the military order of "killing without forgiveness". At the same time, in his mind, the capital of the Han Empire, which will cross the Eurasian continent in the future, is none other than Chang'an. Except for Zhao Xing, no one in this time and space knows what the origin of the earth means, but Zhao Xing knows very well that the origin of the earth in China is near Anling in the northwest of Chang'an! (Note 1) What is the significance of the origin of the earth? If you take the vicinity of Chang'an as the center of the circle on the map, choose an appropriate range, and use the circle to plan a circle, it can cover all the corners of China's southeast, northwest, and north! In other words, if you build a capital here, the distance to the whole country is almost equal, and you can just cover any enemy within range by launching an ICBM here!

If we also consider that Zhao Xing continued to expand westward in the future, and Chang'an was the starting point of the Silk Road during the Western Han Dynasty, then the significance of establishing a capital in Chang'an is even more far-reaching.

In fact, Chang'an is still the capital of the Han Empire, but the emperor is working in the eastern capital of Luoyang, so Chang'an, which has been reduced to the accompanying capital, has declined in political status, but it still can't hide its glorious past. If measured by the number of people, the Sanfu area of Guanzhong is still the first of more than a dozen states in Dahan, and it is the most densely populated!

Fifty thousand Hu cavalry appeared near Chang'an without warning, causing countless panics and displacements.

Zhao Xing urged the troops to march quickly, and before the people had time to flee, they passed through Chiyang, Anling and Changling, and rushed to the majestic city of Chang'an in one breath. Looking at the momentum, if it weren't for the pioneer Ma Xiu, who took the lead, he strangled the reins of the horse, I was afraid that the war horse would crash into the city wall of Chang'an.

50,000 Hu people surrounded Chang'an!

The mausoleums of the previous emperors of the Han royal family are in danger of being destroyed!

This earth-shattering news was finally relieved by the people outside the city, and it was transmitted to the eastern capital Luoyang at the fastest speed.

Soon after the Yumen Pass upheaval, there were concerns about whether the Liang Kingdom's defenses would be able to withstand the invasion of the Hu people in the Western Regions, but this doubt was quickly put to the back of the eye.

Zhou Cang and Guan Yu successively led a large army out of Yumen Pass to rescue Zhao Xing, but there was no news about the mud cow entering the sea, and some people were worried that the Hu people would take advantage of the emptiness of the Liang State to invade on a large scale, but such doubts were soon replaced by the crusade against Zhao Xing.

Zhang Ziwei, an intern reporter of "Jin Daily", risked her life to send a message from Wuwei Guzang, once again reminding the Han people to pay attention to guarding against the invasion of the Hu people, but it only caused a shock in the Liang country, and the people of Chang'an still believed that the Hu people did not dare to attack Chang'an, otherwise there would be no return.

The wolf is coming! the wolf is coming...... If you shout too much, people don't bother to listen to it.

When 50,000 Hu cavalry approached the city of Chang'an at the speed of the wind and clouds, the land of Guanzhong suddenly fell into a panic and panic, and the common people really did not know where to go except for the thought of fleeing east into Luoyang.

Now the north of Chang'an, Huangfu Song, is leading an army to attack the Jin State, and the road to the Jin State is naturally blocked; the road leading from Hanzhong to Yizhou in the southwest of Chang'an is blocked by the army of Yizhou attacking the Liang State; the Liang State in the northwest of Chang'an is even more difficult to go, and it has now become the world of the Hu people; so the common people can only flee to Luoyang from Tongguan in the east of Chang'an, or flee to Nanyang through the mountains and mountains from the Qingni Pass in the southeast.

Huangfu Jianshou, the eldest son of Huangfu Song, who stayed in Chang'an, looked at the Hu cavalry under the city, and a feeling of powerlessness surged in his heart. There are 20,000 Imperial Forest troops stationed in Chang'an, which sounds like a lot of people, but for Chang'an City, which is dozens of kilometers wide and has twelve city gates on all sides, it is still too rare. As long as the Hu cavalry launched an attack from more than three city gates, the defense forces in the city would be in a hurry.

Thinking that his father was now leading the army to the Northern Expedition to the Jin Kingdom, and Chang'an, where he was in charge of garrisoning, was unexpectedly pulled out by a black tiger from the Hu people, Huangfu Jianshou felt that the heavens always seemed to be against the Huangfu family.

Regardless of the progress of Huangfu Song's northern expedition to the Jin Kingdom, when he learned the news of the siege of Chang'an, he must lead his army back to help. In this way, the results of his previous northern expedition to the Jin Kingdom came to naught, and he had to bear the fault of advancing lightly, which led to a crisis in Chang'an.

What Huangfu insisted on was that even if Huangfu Song knew the news of the siege of Chang'an, he might not be able to lead the army back smoothly, because the Imperial Forest Army would soon encounter a strong opponent on the road back to the south.

Note 1: The geodetic origin, also known as the geodetic datum point, is the method of using Gaussian plane Cartesian coordinates to establish a unified national coordinate system, that is, the "1980 National Geodetic Coordinate System" in use now, referred to as the "80 system". The origin of the earth is an artificially defined point, and in the 70s of the last century, China decided to establish its own independent geodetic coordinate system. Through on-the-spot investigation and comprehensive analysis, the origin of the earth in China was finally determined to be in Beihongliu Village, Yongle Town, Jingyang County, Shaanxi Province, and the specific location is: 34°32′27.00 north latitude and 108°55′25.00 east longitude.
