Meng Tian's mood was indeed very chaotic, he had a great difficulty to build the first line of defense, and in order to buy time on the border of Shangjun, he lost many troops that were already lacking.

The news of the Han war against Qi and Yan reached the north, and Meng Tian once felt that he could breathe a sigh of relief, after all, Qi, Yan, Zhao and the Xiongnu were allies, and Han's participation in the war would definitely change the situation, and the news that Qi Wang Dan invited the Huns to rush south also confirmed this.

The grassland Hu people who fought with the Qin army on the border of Shangjun carried out a retreat half a month ago, and the generals of the Qin army, including Meng Tian, thought that it was the Qi State that invited the Xiongnu to have an effect, and the grassland Hu people led by the Xiongnu did not have the ability to fight on two fronts, and they could only abandon the Qin army to support the Qi State.

Of course, Meng Tian and other generals did not believe in their speculation at the first time, they paid close attention to the movements of the retreating Hu people, and more than 200,000 Hu people withdrew directly to the grassland outside Yanmen after retreating, and the intelligence also showed that this group of Hu people was very likely to stop outside the pass for a short rest, and then they would be transferred to the land of Qilu.

Qi, Yan, Zhao, Xiongnu formed an alliance, the dominant of which is the Qi State, since the Han State to the Qi State of the war is a posture of soaring, within three months to occupy the northern part of Surabaya and the East China Sea County, not to mention, when breaking into Xue County and threatening in the direction of Jibei County, the civil and military forces of Qi in various places were unexpectedly surrendered in large numbers, making the Han army advance northward more rapidly.

In this situation, once the Qi State is wiped out at a very rapid speed, and the alliance loses the Qi State that can provide materials, then this alliance will not only exist in name only, but without the materials from the Qi State, there will be no need to fight. Isn't the current Qin State also suffering from this kind of "hijacking"? Once the Han State cut off the material delivery to the Qin State, the Qin State only had the fate of collapse, so it knew that many things were not good, but it was always impossible to mention it.

The Great Wall Army did not carelessly feel that the retreat of the steppe Hu people meant that they were worry-free, and they spent a lot of effort and cost to pay attention to the movements of the Xiongnu and other tribes outside the pass. It was always when the head man led the army to move towards the land of Qilu. Meng Tian and other Qin generals were relieved, but many things were always full of blind spots, and the Great Wall Army paid too much attention to the people of the Hu people's headquarters, and those that were ignored were even more deadly.

In fact, once the army exceeds 200,000, it is not possible to judge with your eyes whether some of the sequences have disappeared, and the grassland Hu people are not like the Chinese army at all, every number has a banner, as long as the number is not outrageous, it is really difficult to detect the lack of one or two hundred thousand people.

Maudun's elite cavalry was handed over to the army led by Touman after he fled back from the Yueshi, and under the training of almost perverts, the 10,000 cavalry given by Touman was actually trained and there were less than 3,000 left.

Of the 10,000 cavalry led by Mao Dun this time, 7,000 still supported him, and the Xiutu Department and the Kun Evil Department each allocated some. I asked for some more, and I made it up piecemeal.

10,000 cavalry suddenly appeared from a location that no one expected, and Pu Yi appeared against a change of guard of the Great Wall Legion.

This time, the Hun cavalry was not so different from the previous way of fighting, they were directly engaged in hand-to-hand combat after a burst of diffuse, and the Qin army, which was caught off guard and extremely tired, collapsed after a long time of resistance, which was regarded as cutting off Meng Tian's defensive change deployment.

If it is just the collapse of a change of defense force that has a faulty impact on the entire defense chain, it is not fatal, and in the next Mao Dun, the remaining more than 7,000 cavalry after that battle were dispersed to carry out a large-scale news blockade, and at this time, the grassland Hu people who were originally transferred to the land of Qilu turned around again. Their march was still in the Upper County.

It seems that it is not enough for the Hu people to turn around, and a Qi-Yan coalition army of about 150,000 people does not know how to hide the scouts of the Qin army, but it appears very suddenly and rendezvous with the Hu people, and then this stage is the moment when Meng Tian discovers that there are many enemy cavalry movements in the territory.

The long march of the cavalry was nothing. Every time the Hu people went south to raid, it was a long-distance raid, but this time the Hu people learned a trick from the Han cavalry, and it was only one of them to divide the small cavalry teams that did not know how many to hunt and kill the fast horses that exchanged news. What's even more disadvantageous is that the battle is no longer fought in the mode of a large corps, and a kind of fight is carried out. If you can't fight and retreat without dragging the mud and water, you can use its high-speed excitement to bite and bite repeatedly, which is not to give the Qin army the trouble of effectively and quickly mobilizing troops for defensive deployment.

Just like the conclusion that Qi Jun has repeatedly suffered. The Qin army soon found that unless they were chasing each other with cavalry, it would not be easy to solve this dilemma.

Meng Tian's Great Wall Legion has always maintained a cavalry infantry formation of 30,000, and in the two-year battle with the grassland Hu people, it was precisely the survival of such a force that did not completely lose the initiative. However, there is a very realistic thing, that is, the loss of less than 10,000 of the 30,000 single-riders and horses of the formation after two years of continuous combat is left. This time, under the premise of repeatedly determining the retreat of the Hu army led by the Xiongnu, the remaining less than 10,000 people were also pulled back to the rear for rest.

When will the Hu people use their tricks? has always relied on absolute strength to shake hard, and he has never known how to hide any intentions. What is even more surprising is that at the moment when the capital of Qi was threatened, Qi Yan actually chose to take out 150,000 people to cooperate with the Hu people to break through the Qin army's defense line, rather than taking out all the troops to block the attack of the Han State.

"In other words, in addition to nearly 200,000 Hu people, there are also nearly 150,000 Qi and Yan troops who have broken through the first line of defense in Shangjun?" The surprise on the lieutenant's face could not be pretended, and he was silent for a while: "Our army can go north in four months at the earliest, but the first batch is only 30,000. ”

The establishment of the entire Great Wall Army is only about 80,000, even if the first batch of 30,000 Han troops went north to participate in the war, under the current situation that the first line of defense of the Qin army was breached, and the second line of defense was in danger, the Qin and Han coalition forces with a combined army of 110,000 troops faced nearly 350,000 Qi, Yan, and Xiongnu coalition troops, it is estimated that it is not enough to see?

"Tian has already played the crown prince and asked for urgent dispatch of the Central Plains Army to the north for reinforcements, but the prince replied that he was worried that the king of Han would have a misunderstanding." Meng Tian's following words don't need to be said again, he must also be worried that the defenders of the eastern gateway of Qin are insufficient, either they will be broken through by the allied forces in the direction of the Central Plains, or the Han State will tear off the mask of hypocrisy and attack Qin directly.

According to the deployment of the entire grand strategy, the Han State will not sit idly by and watch the Qin Dynasty fall within three years, but these cannot be put on the table.

Gongwei really wanted to tell Meng Tian that it was true that the Han army was now marching forward, but the front of the Han army was getting longer and longer, and the logistics line had already gone a little wrong, otherwise it would not have been a direct turn to attack Jibei County, but should have been killed under Linzi City.

In addition, the Han state has accepted Lu Zhe's idea, and the land conquered can only be really owned after digestion, and wanting to digest it is nothing more than an iron fist to eliminate the disobedient, and then win over enough people.

Because the offensive was too ferocious, there was a problem with the supply line of the Han army, and the problem with the supply was that there were too many refugees to consume the grain and straw that was too terrifying, before the group of people went north, Xiao He, who was in charge of the government, had just issued an administrative order to recruit manpower in thirteen counties and counties across the country, and it was also the first time that the government used the act of requisitioning horse-drawn carriages, and it was also mobilized to the merchant class. This was done in order to ensure the transportation of food and straw for the 200,000 soldiers and nearly 600,000 auxiliary soldiers who went north, and at the same time, they also tried to feed the heads of the occupied areas by as many as several million.

In this situation, the Han army in the north will slow down the offensive in a targeted manner because of the supply line, even if the army still has the strength to advance rapidly.

There are still many places affected, such as the mixed army that was supposed to enter Ba County and Shu County, which has been staying, and at the same time, the sixth mixed army that should have gone north to participate in the war has also been forced to stay in Nanling, and the subsequent plan to mobilize some legions has to be postponed.

The reason for this situation is not to blame, the main reason is that the Han State is the first time to engage in this kind of large corps, and the area of the battle is really too broad, simply put, the plan can't catch up with the changes.

Gongwei couldn't explain much to Meng Tian, but he still had some authority to make some replies: "I will do my best to play my king." ”

The words sounded a little clueless, but Meng Tian, who was a martial artist, understood, the lieutenant was talking about the Central Plains Army of the Qin State, and he was also saying that he would transfer the second batch of Han troops who went north to participate in the war in advance.

"It will take four months for the Central Plains Army to reach the northern border at the earliest," Meng Tian looked at the lieutenant, and it would take half a year for the Han army to have a second batch to go north at the earliest, so he continued: "According to the current situation of the war, our side will gradually abandon the Shangjun defense line and retreat the battle line to the vicinity of Neishi County. He stopped and looked at the lieutenant again, "Presumably, the communist general has gone all the way north from Xianyang and has already seen those defensive lines being built?" ”

The lieutenant naturally saw it, but there were many things he didn't understand, and those words were not so easy to ask.

The Qin State had long built a defensive line near Xianyang, and it was obvious that it had a plan to pull the battle line to the vicinity of Xianyang, that is, it had long found that the northern front could not be defeated?

Also, not only did the lieutenant wonder, but many Qin generals probably didn't understand what the situation was in the Qin center, did he really regard the Han State as a lifesaver? Why does the whole deployment seem to revolve around the gamble of the Han State's constant resources and the inevitable dispatch of troops to help the war, if the Han State does not act as Qin Zhongshu expected, what will be the end?

Meng Tian didn't know what the lieutenant was thinking, and after determining some things, he said: "Since you have gone north to observe the Hu people's tactics, our army has just captured the traces of a Hu cavalry, but do you want to watch the battle with you?" ”

The co-lieutenant nodded his head mechanically, and the whole person seemed to be in some indescribable confusion. (To be continued......)
