"Master, can you make it clearer, what did you suddenly say with your head pinned to your trouser belt...... It's kind of scary. ”

Su Yan's words were also what the rest of the people wanted to say.

Along the way, Liu Yu didn't say much, and most of the things about camping and marching were taken care of by Qi Fang. Although Liu Yue is the military advisor of Su Yan, the commander of the army, whether he knows how to march and fight is still a question mark in everyone's heads.

Liu Yu didn't explain too much, took out a cinnabar pen, and drew three red lines on the marching map, the starting point of the three red lines was Shaowuguan, and the end point was Tongguan. There are not too many twists and turns, after all, the hinterland of the Central Plains is mostly plains, and there is no need to take too many detours.

Qi Fang studied the military map, and after reading Liu Yu's three red lines, he was puzzled: "Liu Shenzuo, the Turkic cavalry is on the front line of Ancheng, you ...... How did you draw three of a kind? ”

"I'm drawing the route they might have to take when they withdraw their troops." Liu Yu put down the cinnabar red pen and looked at everyone, "If you have any opinions, just say it." ”

Li Mi said: "Now the Turkic cavalry is about to overwhelm Tongguan...... Talking about the withdrawal of troops...... Early, right? ”

"I don't think it's early, on the contrary, I think it's a little late." Liu Yu picked up a brush that was not dipped in ink, pointed to the military map and said, "The Turkic cavalry drove in from Shaowu Guanchang, there was no baggage, no provisions, and what they fought was the rapid advance of looting grain and grass to feed the war. From the fall of Shaowu Pass to the cavalry pressing Tongguan, it was only nine days before and after. Think about it, what is the purpose of this Turkic cavalry in such a rash advance? ”

Everyone looked at each other again, and Li Mi gave the answer: "I want to stand up!" ”

"That's right. It's Liwei. The Turks changed the khan, the political situation was unstable, in order to show the prestige of the new khan, in order to make the steppe tribes submit, so there was a fierce attack on Shaowu Pass, and the cavalry drove straight in. The soldiers of the Dashun Dynasty have been fighting with the Turkic cavalry for some years, and they have a deep understanding of the Turkic cavalry. ”

Qi Fang had been in the north for many years, and he had a strategic mind, so he had some understanding of the combat power of the Turkic cavalry.

Qi Fang was puzzled: "Could it be the Iron Wolf Guard?" When I was at the border, I heard that the strongest combat power of the Turkic cavalry was the Iron Wolf Guard, whose soldiers had been thrown into the wolf pack since childhood, and those who could fight and kill wolves could enter the Iron Wolf Guard, and the training they experienced afterwards was also extremely harsh. However, this Iron Wolf Guard is the personal guard of the Turkic Khan, and any soldier in the cavalry team that invades the border is at the head level, only heard of it and did not see it! ”

Liu Yu smiled and said: "Most of the Turkic invasions are for plundering, and there is no need for such a strong cavalry as the Iron Wolf Guard, which is more likely to stay on the grassland and deter the rest of the grassland departments." This time is different, if you want to stand strong, you have to be ten and ten stable, who can complete the raid on the Central Plains Liwei and retreat with his whole body? ”

The crowd was in an uproar.

Su Yan was shocked: "What does the master mean? Is that a bunch of barbarians who can kill even a wolf cub with their bare hands? That...... So we ...... We don't seem to be on the route of these three red lines, do we? ”

Qi Fang ignored Su Yan's shouting, and continued to talk about the matter: "What Liu Shenzuo said is reasonable, but even if it is really the Iron Wolf Guard who raided the Central Plains, it may not be able to retreat to Tongguan, after all, it can still be ......."

"You mean capture Tongguan?" Liu Yu said with a smile, "On the one hand, the combat power is not allowed, the cavalry is good at encounters on the flat ground, and even a long-distance cavalry that lacks light baggage, people are not sleepy, and horses will be lacking, how easy is it to capture Tongguan?" I believe that Captain Qi also understands the current guarding Tongguan, well, that is, my father's temperament, he will definitely not abandon the city and fight a decisive battle with the Turkic cavalry outside the city. ”

"Besides, time doesn't allow. Even if the Turkic cavalry can really find a siege baggage to attack Tongguan, after all, there are several large armies behind them to chase and intercept, no matter how strong the combat power is, once it is encircled, it is not easy to get out. ”

"Ten thousand steps back, even if it's really in a short period of time...... This time can be exaggerated to the fact that in one night, the Turkic cavalry captured Tongguan, and they still had to retreat. Because after the Tong Pass, the cities in the Guanzhong are high walls and deep waters, the city is closed, and now it is the spring famine season, the Turkic cavalry has no food and grass behind, and in front of it is the tall city tower of Chang'an City, and there are more than 100,000 chasing soldiers...... Can it not be withdrawn? ”

"At present, I am afraid that the generals of the entire Dashun Dynasty are worried about the situation in Tongguan, and it is rare that Liu Shenzuo is thoughtful and can see the development of the war in advance." Qi Fang smiled in amazement, and then looked at the marching map, "I just don't know, which route the Turkic cavalry will retreat to?" ”

Liu Yu looked at the crowd and said, "I have to listen to your opinions." If you were in charge of the Shuai Yin of the Turkic Iron Cavalry, which route would you choose to withdraw your troops? ”

Everyone was a little curious about Liu Yu's assumptions, after all, they were not the commanders of the Turkic cavalry, but only Liu Yu knew his intentions very well, which was empathy. It is not enough to rely on a person's head to think, and a wise man will make a mistake in a thousand thoughts, and it will be difficult to achieve things.

Li Mi was the first to say: "If it were me, I would choose the route of the Malan Road, first, I can follow the Taihang Mountain, there are many small cities on the route that can be plundered, and second, I can bypass the pursuing cavalry and reverse the return to the Yellow River." ”

Liu Yu said with a smile: "Just like you said, the most critical thing, the four words 'on the edge of the Yellow River', the small mountains and rivers in the middle are not obstacles, but the Yellow River, that is a natural danger, can you swim across the river on a horse?" You chose the downstream again, the river is wide and deep, although the current is not urgent, but there are no reinforcements to pave the road and build bridges in advance, relying on the small boats around you, how many days can you transport tens of thousands of cavalry across the river? ”

Li Mi was dumbfounded.

Liu Yu continued: "No matter how many days, it will take time, but the pursuers of the Dashun Dynasty are coming from the flank, and it is already an ironclad matter to block this Turkic cavalry on the edge of the Yellow River. ”

Historically, the Yellow River was the easiest to divert, and the Dashun Dynasty now has the mouth of the Yellow River close to the Haihe River and is very far north, so the first consideration of the Turks in choosing a retreat route is to quickly withdraw to the north bank of the Yellow River while the lone army is deeply penetrating.

Qi Fang frowned and looked at Jun Tu and said, "It's not good to go downstream, do you want to go upstream?" But...... The line from Jucheng to Tiger Hill is too close to the pursuers of the Dashun Dynasty, and one will fall into the encirclement if one is not careful. ”

Su Yan on the side looked at the last line and said: "That must be the third one, when they came, they took the Anseong line, and the retreat must have returned the same way." ”

Liu Yu glanced at him and smiled: "I went back to others the way I came, and threw myself into the net, right?" ”

Su Yan laughed, knowing that he didn't know how to march, so he stopped talking.

Sui Yi, who had been silent, said: "Since the three can't work, then ......"

Liu Yu picked up the cinnabar pen again and drew a red line on the military map, this time the red line can be said to be very tortuous, first from Tongguan to the southeast, bypassing the Taihang Mountain, from Huaixi County to the north, all the way to the mouth of the Yellow River, the length of this line is more than twice as long as the previous three.

Qi Fang was a little incredulous, and said: "Bypassing Taihang Mountain, it is equivalent to setting up a moat for the pursuers, and there is no garrison on this way, at least to the Yellow River estuary, it can be said that it is a stroke of genius, and there is no better route than this." It's just that, just like Liu Shenzuo's denial of the Malandao route, this route still passes through the lower reaches of the Yellow River, I'm afraid ...... It is not possible to cross the river for a short period of time. ”

Liu Yu firmly said: "This is precisely the best place to cross the river, because ......"

Liu Yu pointed his pen at Shaowuguan and said: "The Turkic cavalry drove straight in, and there was no logistical supply, but there was Shaowuguan as a basis, and it can be said that Shaowuguan was the basis of the Turkic cavalry. Retreating from this way, the mouth of the Yellow River is the closest to Shaowu Pass, but it is only more than 100 miles, and the Turkic garrison of Shaowu Pass can come out in advance to build the pontoon bridge, or find a large number of ships, which can be easily ferried. ”

Qi Fang's face was a little frightened and said, "That's really the case." ”

Sui Yi was puzzled: "Then what if the army of the Great Shun Dynasty snatched Shao Wuguan back in advance and blocked the retreat of the Turkic cavalry?" ”

This time, there was no need for Liu Yu to answer, Li Mi gave the answer: "This is not advisable in the art of war, once the retreat is cut off, the Turkic cavalry is a trapped beast, and the power caused by it increases exponentially, which is why the siege of the city should be surrounded by three queyi." What's more, the focus of the border army of the Dashun Dynasty is to encircle and chase this Turkic iron cavalry that has been driving straight in, and it is only symbolic harassment of Shao Wuguan, and there is no substantive action. If you want to recapture Shaowu Pass, you must wait until the internal troubles are resolved. ”

Liu Yu concluded: "That is to say, the land under our feet, after four or five days, the longest six or seven days, must be the only route for the retreat of the Turkic iron cavalry, I have also calculated, this route can only be ambushed by the Fanru River in the north of Huaixi County, because after Huaixi County, it is equivalent to bypassing the Taihang Mountain, and there is a plain in front, they can choose to pass through many routes, and then they want to set up an ambush than to ascend to the sky." That's why I asked earlier, whether we should avoid it, or stay and fight to the death! ”

Sui Yi said: "Brother Liu, you say...... No pursuers will catch up, but ...... You see the route of the daughter army, it is pressed on the side of the Malandao, if the Turkic iron cavalry wants to withdraw from Huaixi County, the daughter army ...... It's easy to outflank, and when the time comes, ......"

Daughters, yes, daughters.

Liu Yu's face showed a sad color, after all, the daughter army was only more than 20,000 horsemen, and their role as a cheerleader on the battlefield was greater than their role in actual combat, and in front of a considerable number of Turkic iron wolf guards, they were like a group of lambs to the slaughter. Once the Turkic Iron Wolf Guard bypasses the Taihang Mountain through Huaixi County, the daughter army will be the first to come and intercept it, and I am afraid that the entire daughter army will be wiped out at that time.

However, Liu Yu has no way to notify his daughter Jun now, to inform the little daughter of the Xu family who fascinated him. Even if the notice arrives, as the general of the Great Shun Dynasty, will the little girl of the Xu family watch the Turkic iron cavalry withdraw from under her nose without interception?
