When General Qian Bai confirmed the identity of Xiao Wu, who was calling the door under the city, and led people to the place where Zhang Mu and the others were, except for Xiao Wu, the remaining nine people in Zhang Mu's scout team were already paralyzed on the ground.

Shi Tietou, Fu Chuan, and Liang Sheng, the three most seriously injured scout soldiers, were already paralyzed on the ground unconscious, and realizing that Shi Tietou was not dead, and Jiuyuan City was in front of him, Zhang Mu, who was suddenly relaxed, also fell unconscious.

After hurriedly arranging Zhang Mu and others, General Qian Bai simply bandaged Xiao Wu's worn legs and thighs, and then personally carried Xiao Wu to the camp of General Xin Sheng, the supreme commander of the Jiuyuan Army.

Since the Great Qin annihilated the Six Kingdoms and unified the world, Xin Sheng has followed the general Meng Tian to lead the troops stationed in Jiuyuan, Meng Tian was mainly responsible for building the Great Wall at that time, although Meng Tian's prestige in the Jiuyuan army is unparalleled, but the specific military affairs are generally handled by Xin Sheng.

And although Xin Sheng's family is all in Jiuyuan City, he will stay in the Jiuyuan Army camp for most of the year.

When the guards reported that there was an urgent military intelligence report, Xin Sheng had just lay down for not long. Hearing that a scout soldier had brought back an emergency military situation, Xin Sheng turned over and got up without saying a word, put on a robe and came out.

Xin Sheng was very calm until Xiao Wu finished telling the information about the Xiongnu army tortured from the mouths of the captured Hun scout cavalry, and there was not even the slightest discoloration, which made Xiao Wu scratch his head

Could it be that there are other scout teams who have also received news from the Hun army and reported it to the general? Xiao Wu couldn't help but think to himself. Of course, if Xiao Wu saw that the brush that had been holding in Xin Sheng's hand at this moment was already right, he would never think so.

The Xiongnu Mao Dunshan personally led 200,000 Hun cavalry, just five hundred miles north of Yinshan in the depths of the grassland, this news was like a thousand catties of boulder heavily pressed on Xin Sheng's heart.

"Wang Wu, right? Your scout team has made such a great contribution, I will truthfully report to the imperial court to ask for merit, now you go to rest first, and this general will arrange this matter himself." Xin Sheng said and turned his head to the outside of the hall and said loudly,

"Someone. Take this scout down to rest, and the rest of the scouts who will return with him must also be healed with the heart. Wang Wu's news must not be leaked. Violators are killed! ”

"Whoa!"

When the guards carried Xiao Wu down, Xin Sheng hurriedly ran back to the copper case, took out a few pieces of parchment and began to write, and after writing four letters in a row, Xin Sheng put the pen away, and then said loudly: "Someone!" ”

"Your Excellency!" The guards came in and bowed.

"These four emergency military information letters were sealed with fire paint, and they were immediately sent to the imperial court, Yunzhong, Shangjun and Longxi. Remember, these four emergency military intelligence letters were personally escorted by the general's personal guards, and they were sent everywhere day and night.

In addition, the prisoners of the forts of the Jiuyuan Great Wall, especially the tunken of the Henan land, immediately moved all the people to the Jiuyuan City, and the garrison soldiers of the border cities and fortresses, especially the Wolf Mountain, did not leave their bodies from now on, took strict precautions, and went out two hundred miles north of Yin Mountain before the scouts to investigate the enemy's situation day and night, and there must be no mistake. ”

"Whoa!" The guards heard that the military situation was urgent, and as a result, the letter was about to go out.

"Wait." Xin Sheng suddenly shouted, "Forget it, you should act quickly!" After thinking about it, Xin Sheng waved his hand to let the guards out.

Xin Sheng just wanted the guards to light the beacon (that is, the beacon tower), but after thinking about it, the Hun cavalry was still in the depths of the grassland north of Yinshan, and he still had time, and the rash burning of the beacon at this moment would inevitably lead to chaos in the counties of Jiuyuan.

There are two main ways for Meng Tian to build the Great Wall, namely the Earth Great Wall and the Stone Great Wall.

The Great Wall was mainly built on deserts and plains, and was built with rammed earth using the slab construction method; The Great Wall of Stone is mainly built on a mountain ridge and is made of stones or stone barriers.

Fengsui, Tinghou, Border City, and Hoarding Fortress are the four main facilities of the Great Qin Great Wall.

When encountering the enemy's situation, it ignites dense smoke during the day and lights torches at night. Pavilion Hou is a very high lookout, there is a pavilion on it, so it is called Pavilion Hou, in order to facilitate the observation of the enemy's situation, many beacons and pavilions are far beyond the Great Wall.

Border Castles are a number of small cities surrounded by strong walls along the Great Wall, which are the residences of soldiers and civilians on the border areas. The areas through which the Great Wall passed were sparsely populated, and it was difficult to supply the army, so the army guarding the Great Wall cultivated farmland near the border city to ensure food supply.

Within the Great Wall, a certain distance from the rear of the Great Wall, Meng Tian built the Tunjun Fortress, which could not only accommodate a large number of troops, but also hoard a large number of logistics materials. When attacking the Xiongnu, it became the advance base of the large army, and it was also the strategic depth of the Great Wall defense line.

This is the Great Wall strategy led by Meng Tian, and with this system, the troops can avoid helpless field battles.

Although Xiao Wu and the others had already dealt with the arrowheads and other objects that left traces of the Qin army, Xin Sheng knew that although they had covered up some traces of the Great Qin soldiers, this could only make the Huns sure that they would be discovered later.

You must know that in addition to wolves on the grasslands north of the Jiuyuan Army, only the scout cavalry of Great Qin can pose a threat to the Hun scout cavalry. The Huns were equally aware of this problem.

After dealing with the traces, the Huns will sooner or later guess that it was the Great Qin scouts who did it, and I am afraid that at this time the Huns have discovered that the scouts are missing. If the Huns were really rushing towards Jiuyuan, then after knowing that their whereabouts were exposed, the Xiongnu would definitely speed up their march and rush straight to Jiuyuan.

This is also the reason why Zhang Mu and others have been running for two days and two nights without sleep.

More than 500 miles away, at most five to six days the Hun cavalry will arrive in Jiuyuan. Xin Sheng calculated silently.

In fact, 200,000 Hun cavalry Xin Sheng is not worried at all, although at this moment the Jiuyuan Army has been transferred to Xianyang 100,000, but the Jiuyuan Army, which had defeated 500,000 Hun cavalry with 300,000 troops, is now not afraid of the Hun cavalry in a one-on-one situation.

Xin Sheng was worried about the people in the border cities and counties in Jiuyuan, as well as the grain that had just been sown in Henan and other places. With the murderous surname of the Huns, they will definitely burn and loot everywhere, and under the trampling of a large number of cavalry, there will definitely be little food left.

In the past, every time the Xiongnu went south, there would always be a message from the Jiuyuan army in advance, so that Jiuyuan could also have enough time to be on guard and report to the imperial court, but this time the Xiongnu went south and did not send any news, which made Xin Sheng's worry even worse.

Meng Tian fought against the Xiongnu in the past, and the Jiuyuan army was all out of the west of Wolf Mountain, and the battle was selected to be far away from the jurisdiction of Jiuyuan County.

Wolf Mountain is the place where Li Mu, the former general of Zhao State, once resisted the Xiongnu, and it is a place with steep terrain in the westernmost section of the Yinshan Mountain Range, and it is also the place where the Xiongnu must pass through to attack the Hetao Plain in the south of Henan. Li Mu once built a large number of Tibetan soldiers and caves here to ambush the Hun cavalry.

Now Wolf Mountain has been built by Meng Tian A large number of fortresses and trenches have been built to prevent the Hun cavalry from driving straight south to all parts of Jiuyuan. Wolf Mountain has always been garrisoned by at least more than 10,000 soldiers of the Jiuyuan Army.

But now in the face of the 200,000 troops of the Huns swarming south, these more than 10,000 soldiers are obviously unable to resist. But now that the imperial court has not issued an edict, Xin Sheng cannot mobilize a single soldier even though he is a general of Jiuyuan, and Meng Yi, who has an edict, has not yet arrived in Jiuyuan at this moment.

"Xin Yuan!" Xin Sheng said loudly.

"The last general!" A rugged-looking general in his thirties responded and hugged Xin Sheng.

"Xin Yuan, you immediately lead the general's personal soldiers to the Wolf Mountain Fortress, if the Huns attack, you will immediately ignite the beacon, and the general will bring troops to help. However, if the general has not led the troops to arrive, if the Wolf Mountain Fortress is taken down, you will wait to see it! ”
