Early morning.

A rapid sound of horses' hooves woke up the Wulong Hanyi Cheng in Pizhou from his sleep.

The white straight young man who served him knocked on the door and came in to tell him that there was an urgent delivery from Chang'an. Zhao An hurriedly got up, and the dusty post guards were gobbling up in the rest area of the post station.

When eating, the package on his back was not untied.

When Zhao An arrived, the postman hurriedly put down his chopsticks.

"Hurry up the post letter, please arrange for the post guard and the post horse relay to deliver the letter."

"Where?"

Zhao An checked the identity credentials of the post guard, and asked him after confirming that it was correct.

"Changwu City, to Zhao Guogong."

The early winter dawn in western Kanchu is dry and cold.

A few postmen were feeding the horses fodder in the stables, and the officials resting in the lodgings had just gotten up, and the morning was busy as usual.

Wulong Hanyi is on the edge of the official road of Pizhou, with the city of Pizhou on one side and the Jing River on the other. In the early morning, you can still hear the sound of soldiers training in the Pizhou military camp in the distance, and you can hear the sound of flowing water in the Jing River.

It is still eighty miles away from Changwu City.

Wulong Han Station, just a small point in the post post system established since the Qin and Han dynasties, this is a square earthen castle, there are more than 100 steps on each side, the outside is the earth rammed and the city is more than a zhang high earth wall, only one door is opened, there is a corner tower by the door. The post city is divided into a stable area, a lodging area and an office area.

In the Han Dynasty, the post station was known as the blood of the country and was an important support for the transmission of national official documents and decrees.

The issuance of imperial court decrees, the reporting of local conditions, and the reception of officials are all completed by this post station.

In some cases, these stations even served as military fortresses.

Wulonghan Station is under the jurisdiction of Pizhou, with 40 post soldiers, 40 post horses, 20 stagecoaches, and post cattle.

From Chang'an City to Dunhuang, there is a post station every 20 miles on this road.

Although the world is now in turmoil and all parties are divided, the post stations in the various powerful territories have not been abandoned and interrupted, and are even busier than before.

A post guard took the letter from the post officer, carried the post letter delivered by the previous post guard, rode the post horse that had been fed, and left the post station, heading for Changwu City, which was eighty miles away.

"Has anything happened in Chang'an City recently?"

Zhao An personally made a cup of tea for the post man, who had already completed the task, and would rest here for a day, and then return to his post station eighty miles away to resume his life.

After the post man had eaten his fill, his body was a little more refreshed.

He picked up the hot tea, took a sip, and found that it was very good, and he immediately recognized that this should be a good tea for the officials who passed along the way, and usually they did not have a chance to drink it.

"Xie Zhao Yicheng."

"It's all the brothers of the post station, what's polite."

"I'll tell you in a whisper, don't spread the word, King Tang is going to move the capital."

"Moving the capital? Why? ”

"Because Luo Cunxiao, the king of Wei in Eastern Qin, has just defeated the 200,000 Eastern Expeditionary Army led by His Royal Highness the Prince of Tang in Hongnong, His Royal Highness only brought back 8,000 remnants, Wang Shichong took 3,000 remnants to Wuguan, and the 60,000 troops led by Yang Shuai were preserved, but they were separated from the north of the Yellow River, and now Tongguan is only more than 10,000 people stationed, and the King of Tang said that Chang'an is difficult to defend, and he has decided to move the capital."

"The Great Defeat of the Crusade? Moving the capital? Where to move? ”

Yicheng Zhao Anxin was shocked, just like he heard that the Son of Heaven was killed in Jiangdu.

"Does Luo Cunxiao bring a lot of soldiers?"

"It is said that he only led an elite army."

The first army, the first army of the Qin army, was only twenty-four thousand.

20,000 4 defeated 200,000? Even if Yang Shuai's 60,000 horses on the North Road are still there, His Royal Highness the Prince of the World also has 140,000.

·······

Song Qizi, the post guard of Wulonghan, rode a stagecoach all the way, and it only took half a day to rush to the foot of Changwu City, which was eighty miles away.

At this time, the Western Qin army besieging Changwu City had retreated twenty miles from the city and camped down and no longer attacked the city.

The post guard logo on Song Zizi's back made him enter the city quickly.

City.

Zhao Guogong and marching marshal Li Shimin were discussing the military situation with the generals.

"Yesterday, another member of the Western Qin Military Academy secretly came to vote, this is already the seventh officer to vote in a few days, from their confessions, it can be confirmed that Xue Rengao's military rations have run out, and the rear can no longer be transferred and supplied. The food in Xue Rengao's camp can only last for another ten days at most. ”

All the Tang generals were very excited.

Surrounded by 200,000 Western Qin troops, but there are only 20,000 people in Changwu City, this pressure is not ordinary.

Li Shimin learned the lesson of the last defeat, and this time he retreated and resolutely did not go out of the city to fight. And his shrinkage is two whole months.

In two months, the men and horses of the Qin and Tang armies were boiled to a nervous breakdown.

The people in the city are worried and scared all day long, and those outside the city are also crazy all day long, but Li Shimin just doesn't fight, so it drags on for two months, Li Shimin is fine, Changwu City is easy to defend, and there is enough food and grass. But Xue Rengao outside the city is pouring the country to fight, a full 200,000 horses, including many cavalry, people eat horses all day long, although the Longyou region is also very rich, is a grain-producing area, but after all, it is not as rich as the eight hundred miles of Qinchuan in Guanzhong, not to mention that he is a guest army, there is grain in the rear, and it is difficult to transport. Over time, the problem grew.

"Report, the Tang King of Chang'an has arrived."

A guard was on the sidelines to report.

Li Shimin asked people to present the letter, and after reading the letter, there was no change in the expression on his face.

"Marshal, a letter from the King of Tang, what's the matter?"

"Oh, it's nothing, it's just that the prime minister sent a letter to ask, how long will it take to defeat Xue Rengao." Li Shimin folded the letter and put it in his arms, and then a smile appeared on his face, "Let's continue to discuss." ”

"Marshal, since the Xue family's cub has no food, then let's continue to spend it with him." A general colonel Liu Gan said.

But Li Shimin, who had been a turtle for two months, shook his head.

"Since Xue Rengao is out of food, then he will most likely have to withdraw. We can't let him withdraw so easily, or he will come back one day. ”

"Marshal, but if we go to war, I'm afraid that Xue Rengao will fall into the arms, and he can't wait to fight now."

The Xue army is mainly cavalry, among the 200,000 horses, although there are also many Qingzhou thieves, etc., but there are many mountains and rivers in Longlong, here has always been a place to send war horses, and the Sui Dynasty also set up many pastures in Longyou before. Not to mention, in Xue Rengao's army, there are many Longyou Qiang soldiers, and they are all naturally good cavalry.

If it is a field battle outside the city, the opponent has many soldiers and many cavalry, but I am afraid that it will be difficult to defeat them, and if it is not good, it will be crushed by their sixty or seventy thousand cavalry.

Li Shimin's fingers tapped on the table, and after reading the letter, his heart was turned upside down.

He was a little flustered.

Li Jiancheng's Hongnong army was defeated, which had put Chang'an in an extremely dangerous situation, Li Yuan sent a letter to ask him to immediately send troops and horses to reinforce Tongguan, and at the same time, Li Yuan also told him that in order to avoid the edge, just in case, he had decided to go out of Qizhou and move the capital to Nanzheng City in Liangzhou, that is, Hanzhong.

If Tongguan is lost, Chang'an can't hold it, he will move to Shudi Chengdu again, in short, to fight to the end.
