In the political hall, Li Xu frowned and looked at the latest report, this is a secret report sent seven days ago, sent by the spies buried in Qinzhou by the Ministry of War, Tubo Zan Prangdama ordered all the men and horses in Qinzhou, and the whole army is about 50,000. It came east along the Weishui area.

The aroma of incense permeated the government hall, and although it was filled with calming cloves and borneol, the meaning of anxiety could not be dispelled by this little medicinal power.

"Eight hundred miles of Qinchuan, Qin and the six countries rely on their geographical advantages. Pei Du's head rested on the palm of his hand, and the fatigue of the left servant of the Shang Shu who came one after another was fully revealed. "It's ripe again, the Tubo people came so quickly, and now it's too late to let the counties clear the walls. ”

In fact, the agricultural conditions in Guanzhong are not good, the vast majority of plots are the Loess Plateau, the real essence is from Weishui to the east, the south is the Qinling Mountains, the Guanzhong Basin is the loess high slope, starting from Baoji, Fengxiang to the east to Tongguan, showing a trumpet.

Since the capital is Baiyujing, the Guanzhong Basin is the core of the Yu Dynasty, although it is no longer the grand occasion of the past.

The route of the Tibetan people is very easy to judge, the march of the army must follow the water source, and they will definitely advance along the Weishui and approach Bai Yujing. This year, it is easy for the people to get a good harvest, but unfortunately in the end, the bamboo basket will be empty.

After the Tibetan people are gone, in addition to those who were taken away as slaves, how should the remaining victims of the war be appeased? Where will the materials and grain for pacification be mobilized, and next year spring plowing will be organized to resume production.

"For the past four or five years, Langdarma has been so busy destroying the Buddha that he has not had the time to come. Han Gang looked at the empty political hall and knew that it wouldn't be long before two more old friends would sit here.

"There's been a bit of slackness everywhere. Han Gang frowned: "In previous years, the Kwantung troops would be dispatched to the customs to defend the autumn, but this year Cheng Qili died, the Privy Council was a mess, I couldn't figure it out, and the defense arrangements were also a mess." ”

Since the appointment of eunuchs to the military, the privy envoys appointed by the eunuchs have become the de facto supreme military commanders. In previous years, Yu Fuguo was responsible for the autumn prevention work, and after he went north, this burden fell on Cheng Qili.

Now Yufu is entrenched in Taiyuan, and it is like an enemy country with Bai Yujing. And Cheng Qili has just been conferred, and the entire Privy Council is now cleaning Cheng Qili's residual poison, and the work efficiency has naturally decreased a lot, intentionally or unintentionally.

"In fact, according to the experience of previous years, the Tibetan invasion of Tibet was swept along the western front, and the troops were divided into many routes, and they never went deep into the interior, but only grabbed a few prefectures and counties and retreated. "As an old minister with rich experience in pacifying the feudal towns, Pei Du's military strategy is still relatively reliable. "Langdarma has been in the Logos for many years, and according to his character, if he does not move, he must be astonishing. ”

Pei Du looked at Li Xu and gestured his fingers on the topographic map of mountains and rivers on the table.

"Qinzhou, Minzhou, Weizhou, these three states stand together, and Weizhou is Longxi County in ancient times. This is a beautiful place in the upper reaches of Weishui, and if I gather a large army, I will definitely assemble here, because there is an abundance of products, and there is no need to waste manpower and material resources because of transshipment. Pei Du made a comparison on the map: "If I have no less than 50,000 troops in my hands, I will definitely follow Weishui all the way to the east and approach Bai Yujing." If you can kill the Xianyang Bridge within five days, then you are done. ”

Li Xu looked at the map, Qinzhou, the gathering place of the Tubo army, that is, Tianshui, was only four hundred miles from Fengxiang. Thanks to Wen Yuanheng's blessing of letting him read more history books, Li Xu has a general understanding of the marching speed of the army.

Not to mention those slow tortoises, if the elite cavalry rushes forward, Li Xu remembers that in the last years of the Northern Wei Dynasty, Gao Huan defeated the remnants of the Erzhu family, and his brother-in-law Dou Tai had a record of leading the cavalry to run three hundred miles a day, even if there were exaggerated factors, four hundred miles was actually just two or three days' road.

If Langdama sent elite cavalry to assault along Weishui, now that the autumn harvest had just ended, the supplies would be easy to loot, and his vanguard would be able to reach Fengxiang City in two or three days at most.

There are only two or three days, and it is still a question whether the new Fengxiang Army can assemble the Fengxiang Army in two days, and Li Xu does not think that Han Rui's Fengxiang Army will be able to stop Langdama for long.

Moreover, Fengxiang is in the north of the main stream of Weishui, if Langdarma is determined to go east, he only needs to leave an elite cavalry to monitor Fengxiang. After Fengxiang, three hundred miles to the east is Bai Yujing, and changing to a scud like Dou Tai is a day's work.

In other words, if Langdarma had the heart to gamble big and send elite wolves to rush to the chest, then his own response time would not be more than two days.

In two days, the city defense of Bai Yujing may not be enough, let alone form an army that can compete with Tubo.

"We don't have much time, two days, no more than three days. Pei Du's judgment was similar to his own: "The soldiers and horses of the Jingyuan Jiedu and Suining Jiedu envoys can't be adjusted, and it's useless to adjust them, and they can't be adjusted." ”

The Jingyuan army was stationed in the northeast of Fengxiang, and the envoys of the Suining Jiedu were in the northwest of Baiyujing, they were all close to the feudal towns of the Tubo-controlled area, and those soldiers would definitely not do it, after all, their hometowns were also threatened by the invasion of Tubo.

"Now available, there are only the troops of the Tongguan defense envoy, but there are not many people in Tongguan, so they may not be able to rush over in a hurry. Pei Du calculated the strength of the troops at hand.

Although the Shence army in the capital is unreliable, it is still okay to defend the city, with Jin Wuwei as the overseer, they are also Bai Yujing's people, and the defense of the city will naturally be deadly.

In fact, there is another choice, Pei Du looked at Han Gang, he could think of it, and the old prime minister could naturally think of it, in fact, this choice was the safest. But the one squatting in Fengxiang is Han Xiang's most distressed son, and this old father will never say that idea.

Slide.

That's right, the traditional wisdom of the emperors of Dayu: if you don't make a decision, you will be fine.

In the Kanto Rebellion that year, Emperor Ming quickly ran to Yizhou for refuge. Later, when the God Emperor was in turmoil, the White Jade Kyoto was occupied by the rebels, and the God Emperor still ran to Yizhou.

Now Jiannan Xichuan Jiedu envoy Li Jifu is the emperor's most trusted official at present, in fact, this time he can also run away to Yizhou without saying a word. The Tubo people robbed such a metropolis as Baiyujing, and they would naturally return satisfied with the money they had made.

It's just that it means that the heroic martyrdom of the second son of Han is almost a foregone conclusion, how could Han Gang allow this kind of thing to become a reality.

Although Lao Linggong is silent now, the Sichuan character on his brow still shows that he is anxious. It's just that he colluded with Cheng Qili because of the emperor's taboo, and now Fengxiang Jie Du is his own son, and the old minister is really not easy to speak.

Li Xu frowned, Pei Du's analysis is a meaning, we have no cards to play in our hands, it is better to shrink our heads and be turtles.

But where is the turtle so good?

The Emperor frowned, and had almost seen the end of what he was referring to.

The size of the Tubo army was close to 50,000, and the number of troops in the whole country was only 3 million, and the mobilization rate of 60 to 1 was obviously the result of careful preparation, and it would take at least half a year.

It can be said that no matter whether he wants to recover Victoria or not, whether he kills Cheng Qili or not, the Tubo people will come over and grab it.

However, the vast majority of people in this world are not capable of thinking about this level.

What they saw was that they wanted to recover Victoria, so they attracted the Tibetan invasion. killed Cheng Qili, who supported his own merits, so he was powerless to resist and could only be a turtle with a shrunken head.

If there are any third-rate historians and first-class scholars who say that they killed Cheng Qili because they listened to slander, then Cheng Gonggong is estimated to become a national hero in the future, a peerless master who has lost hundreds of miles in one hand.

In name only, this is the end of yourself.

This Rhondarma is really good at picking the time. Li Xu looked at the map, now is the time when he is first in power, and it is also the weakest time, once he does not deal with it well, what awaits him this time is the situation of centrifugation up and down.

"Concentrate your forces to defend the city. Pei Du said: "I ordered the Jingzhao counties to clear the walls and clear the wilderness, and move the people to the east for refuge." ”

"I'm afraid it's too late. Han Gang stood up and said: "The speed of the Tibetan march is extremely fast, and the sergeants all ride horses, and only after encountering the enemy do they start to meet the enemy with a foot team. Now it's time to run, and it's too late for the common people. ”

Li Xu looked at Han Gang and Pei Du, he actually had another idea in his heart, but he didn't know if he could still trust the two rulers in front of him.
