After 30,000 light horsemen broke away from the Qin army's formation, they quickly passed through the entire territory of Shangjun to the west, and then turned north and entered the grassland along the old road of the Great Wall. More than 40,000 foot soldiers and minfu continued to pretend to be the main force to the north to Wuchuandu, where they used ferries to transport boats across the river during the day, and secretly pulled the army back at night.

Because the Qin army was heavily guarded, Sima Xin's spies could not get close to the ferry, so they could only watch from a distance, so they did not see the Qin army's tiredness. However, Maudun's army was worried about startling the snakes, so they did not set up an ambush on the other side of the river, but camped hundreds of miles away, hoping to wait for the Qin army to cross the river and then rely on the impact of the cavalry to annihilate it in one fell swoop.

After receiving the news from the scouts, Mao Dun had been patiently waiting for the Qin army to advance eastward. In order to prevent the Qin army from being vigilant, he even issued a strict order prohibiting any rangers from leaving the camp, and the residents along the coast had already been swept away.

It wasn't until after waiting for ten days that he still didn't see the shadow of Qin Jun, and Mao Dun noticed something was wrong. He led the army into the camp set up by the Qin army on the bank of the river, but found that the Qin army had already gone to the camp empty.

Mao Dun was shocked and suspicious for a while, he couldn't help but remember that three years ago, when the main force of the Xiongnu was going south, the Northern Army crossed Mobei and attacked the royal court, so he couldn't hold his breath anymore, and hurriedly sent the right general to lead 30,000 cavalry back to Longcheng to be on strict alert to prevent the Qin army from repeating its old tricks.

He himself divided the remaining army into several teams and roamed around the land of Yanmen in the clouds, looking for this Qin army that had disappeared out of thin air. At the same time, people guarded every pass leading to Yanmen City here to prevent the Qin army from rushing to Yanmen City to join the northern army.

Received a report from the scouts that the Qin army had indeed crossed the river ten days ago. Mao Dun not only had the heart that the Qin army had already turned around and fled back to Guanzhong, but he must have known that the movement of an army of tens of thousands of people crossing the river must be very large, and it was impossible for the scouts of the Huns not to find out.

Therefore, Mao Dun concluded that the Qin army must have hidden traces and quietly escaped the encirclement of the Huns in the land east of the river.

It's just that his army searched along the river for more than ten days, but found no trace of the Qin army. This made Mao Dun a little suspicious, thinking that the Qin army might have colluded with the Zhao army in the south, and maybe he was preparing to attack the Xiongnu through the Zhao realm, so he ordered to increase the patrol area, and included the border with Taiyuan and Dai County in the patrol place.

Just when Mao Dun was racking his brains to find the Qin army, Han Xin's 30,000 light cavalry had already left the abandoned old road of the Great Wall, galloping all the way to the north, trying to detour to the back of Yanmen to attack the unsuspecting Xiongnu army.

Han Xin had expected that Sima Xin and the others would be uneasy and kind, in order to protect themselves, the two would definitely try their best to hold back the Qin army, and betraying the news to the Xiongnu was undoubtedly the best way. Not a single soldier was dispatched, but the main force of the Qin army was completely annihilated by the hands of the Huns, so why not? Even Han Xin couldn't think of a reason why the two would not do this.

Therefore, he resorted to the strategy of attacking the east and the west, and just used the mouth of the two to divide the Xiongnu army into two, and Mao Dun would definitely leave a sufficient number of troops under the city of Yanmen in order to maintain the blockade of the northern army.

It's a pity that Sima Xin and Mao Dun thought they were praying mantis catching cicadas, but they didn't know that Huang Que was already behind, if they were calculating people's hearts on the battlefield, who would be Han Xin's opponent?

After the army left the Great Wall, the fast horses did not stop, carefully avoiding the populated places along the way, if they met the herdsmen of the Huns, they were all killed, leaving no one alive.

Although the land of Mo Nan was not included in the territory of the Qin State back then, when the Qin State was strong in the past, Mo Nan was the deterrent range of the Northern Army. The powerful northern army often cruised north in search of the Xiongnu tribes, so as to obtain heads and earn military merits. In order to avoid the continuous attacks of the Qin army, Tou Mancai led his tribe across the desert to take root in Mobei, and Monan was abandoned.

Therefore, the northern army's understanding of Monan is not inferior to that of the Huns, and may even win. Because the Qin army had a detailed survey in Monan, and drew a map for the generals to use on the march, every mountain and river was roughly marked on the map, which created extremely favorable prerequisites for the Qin army's sneak attack.

At the beginning, among the subordinates brought back to Guanzhong by Han Xin, quite a few were veterans of the Northern Army, who had rich experience in fighting on the grassland, but there were no dangers along the way, and they were occasionally accidentally discovered by the herdsmen and dealt with in time. The only exception was when they collided head-on with a small tribe of Xiongnu grazing south by the river at dusk, and both sides were stunned.

The Qin army was the first to react, Meng Shi took the lead in leading his troops to rush into the ranks of the Huns, and Xi Da and Yingbu, who arrived later, divided their troops to surround them left and right to prevent the Huns from escaping. After a bloody battle, this small tribe of 30,000 Huns completely disappeared from this world, leaving no living mouth.

The disappearance of such a large tribe would definitely attract the attention of the Xiongnu garrison, so Han Xin once again accelerated his march, and the 30,000-strong army quickly turned south, rushing towards the clouds in the south, and finally arrived at the Great Wall in the middle of the clouds fifteen days after leaving Shangjun.

The Great Wall is divided into two sections, the First Emperor originally connected the Great Wall of Qin, Zhao and Yan to form the Inner Great Wall, and Yanmen County belongs to the southern foot of the Inner Great Wall. After Meng Tian drove the Xiongnu to the north and obtained a large amount of territory, the Qin army's defense line advanced hundreds of miles to the north, so a new section of the Great Wall was built to connect the old Great Wall, which was the outer Great Wall, and Yunzhong belonged to the outer Great Wall defense line.

The Great Wall was originally used by the agricultural civilization to defend against nomadic tribes, and the Huns themselves were nomadic tribes, so they naturally abandoned it after occupying the Great Wall. The north is the grassland where the Huns are based, so Mao Dun simply dispatched some old and weak soldiers to several passes of the Great Wall to ensure that the materials plundered in the south can be smoothly transported to Longcheng through the passes.

The paralysis of the Huns also provided an opportunity for the Qin army to take advantage of, Han Xin carefully selected dozens of people with high martial arts from the army, took advantage of the night to climb the wall to kill all the Hun soldiers guarding the beacon tower, and opened the gate of the pass. Then the Qin army rode through the river, all the way south as if entering a no-man's land.

There are six Helian Mountains in the Chinese New Year's Eve, although his surname is Helian, but he is the same clan of the Xiongnu Shan Yu, a branch of the Sulu family. His grandfather was given the surname Helian Mountain by the Xiongnu at that time because of his bravery and repeated military exploits, which means that he is as tall and majestic as Helian Mountain, and their family has taken Helian as his surname since then.

Helian Shan served as the general of Zuo under Mao Dun when he was the king of Zuo Xian, and he has always been loyal to Mao Dun, even after Mao Dun was deposed, he still sent people to secretly express his loyalty from time to time. In fact, it also proved that he bet on the right bet, the young prince Fu Erjian was really not the opponent of the scheming Mao Dun, after learning that Mao Dun ascended to the single position, he was also the first to lead his troops to take refuge in the old master in Mo Nan.

Maudun was grateful to him for this, and promoted him everywhere. In less than half a year, Helian Mountain has become the king of the right valley, ranking fourth in the twenty-four longest Huns. Because Mao Dun was young and strong, he did not set up a prince, and the position of King Zuo Xian was vacant. In addition, because of his advanced age, the right virtuous king Drathi rarely cares about government affairs, so Helian Mountain is actually already the number three person in the Huns, second only to Dadan Yu Maodun and the Zuogu Liwang who stayed in Longcheng.

Helian Shan is not a blind opportunist, he is a wise general with both civil and military skills among the Huns who respect bravery, so he is very temperamental with Mao Dun, and is accepted by Mao Dun as a henchman. Mao Dun led his army south to ambush the Qin army, and handed over the remaining 100,000 troops to his command.

Because the city of Yanmen is high and deep, it is difficult for the Huns, who lack large-scale siege equipment, to bite it down with the advantage of numbers, and Maodun's initial strategy is to surround Yanmen and want to trap hundreds of thousands of soldiers and civilians inside. After the Maodun army went south, the Xiongnu's strength was tight, if they wanted to surround the huge Yanmen City, it seemed a little powerless, Helian Mountain gathered the army, and confronted the defenders in the city outside the north city gate, and the other three gates sent patrols and cavalry to warn around the clock to prevent the Qin people from escaping.

Helian Shan was not worried that the Qin army would break through, you must know that there were still as many as 60,000 Qin troops in Yunzhong City, and the reason why they were defending Yunzhong was because there were still two or three hundred thousand civilians in the city who had not had time to evacuate. These civilians were all parents, wives and children of the Northern Army, so Helian Mountain expected that the Qin Army would not break through alone.

If the Qin army wants to take these women and children to break through the encirclement, then it is in line with the intentions of Helian Mountain. On the plain, the cavalry of the Huns could definitely easily catch up with the Qin team that fled south in a hurry, killing them all on the way to escape.

To his disappointment, the Qin army guards did not make such a low-level mistake, although Helian Mountain only blocked the north gate and allowed the Qin troops in the other three directions to enter and exit freely, Wang Jing saw that this was a trick of the Huns, and still stuck to the city and would not fight easily.

It's just that the daily consumption of grain and grass by more than 300,000 people in the city is undoubtedly an astronomical amount, although Wang Jing collected the heavy grain and grass in the north in advance, but still suffered heavy losses in the frenzy of the Hun attack. When the city is full, the grain and grass in the city will only be enough to support another month at most. If there was no turnaround after a month, then Wang Jing had no choice but to abandon most of the Qin people and take the Qin army willing to go with him to break through and return to Guanzhong.

Helian Shan saw that the Qin army guards were not fooled, and he had no choice but to continue to confront outside the city. A few days ago, he received news from Mao Dun that the reinforcements sent by the Qin State had disappeared after crossing the river, and he was asked to be vigilant to prevent being taken advantage of.

After receiving the news of Mao Dun, Helian Mountain naturally did not dare to be careless, and ordered the scouts to expand the scope of inspection, and sent a large number of rangers to the east, west, and south to search for the main force of the Qin army, but the north did not attract his attention. This can't be blamed on him, the north is connected to the land of the Xiongnu in the south of the desert, with high mountains on both sides, and only a small road leads to the territory of the Xiongnu through the pass of the Great Wall.

Unless the Qin army had grown wings and flown over the mountains, it would never have been possible for the army to attack from the north. Helian Mountain thinks so.

"General." The soldiers gently woke up Wang Jing, who was sleeping, and Wang Jing opened his bloodshot eyes.

Having just woken up from a deep sleep, he looked very tired, and it took a long time for him to come to his senses, lick his dry lips, and asked in a hoarse voice; "What's the matter?"

Since the Xiongnu besieged the city, Wang Jing has not slept well, and even when he fell asleep, he was still armored and ready to go to the battlefield at any time. Today, he inspected the position until late at night, and just returned to sleep when he was woken up by his own soldiers.

"Qiu Junhou, who is on duty tonight, is outside the tent, saying that there is an emergency to see you."

Wang Jing suddenly came to his senses and said; "Let him in."

Qiu Shi walked into the tent and simply made a military salute; "General Right, I'm sorry to disturb your rest, but I feel that there is something wrong with the Huns."

Wang Jing said in a deep voice; "Are the Huns going to attack?"

Qiu Shi shook his head slowly; "No, I don't know how to say it, their camp looks a little strange, you'd better go and see for yourself."

Wang Jing followed Qiu Shi to the top of the city and stepped onto the highest lookout.

Although it was August, the cool breeze at night was still a little cool, Wang Jing was only wearing armor, and he couldn't help but shiver, and he was much more energetic.

"Look at the camp of the Huns." Qiu Shi pointed to the Hun camp in the distance, and Wang Jing looked at it, only to see a faint fire dancing on the edge of the sky.

Helian Shan was worried that the Qin army would sneak out of the city to attack him, so he cautiously arranged the camp ten miles away, so it was not very appropriate to look at it from the head of Yanmen City, and he could only vaguely see a piece of fire, which looked a little dazzling in the dark night.

Qiu Shi saw the doubt in Wang Jing's eyes, so he explained; "The light of the fire, which appeared only a quarter of an hour ago, I saw it and hurried to report it to you, the general. It's not like an ordinary fire, if it is, it doesn't make sense that it would set fire to most of the battalion so quickly, so ......."

Speaking of this, Qiu Shi didn't speak, just looked at Wang Jing, Wang Jing naturally heard the meaning of his words, and muttered; "You mean someone deliberately set the fire?"

"Yes." Qiu Shi nodded, with a vague excitement in his tone, "I think it may be that our reinforcements are coming, and they are sneaking up on the Huns' camp." General Right, you said we should go out of the city to answer. ”

Wang Jing was not overjoyed, but calmly said another possibility: "Do you say that the Huns deliberately lured us out of the city, if they are really attacked, it should not be from the north, the north is their own territory." ”

Qiu Shi was stunned for a moment, and then said suspiciously; "Look at the fire, the Huns burned down most of their camp in order to lure us out of the city? Seems unlikely. ”

Wang Jing didn't speak, cold sweat was already breaking out on his forehead at this moment, and he kept telling himself to be calm, calm, and calm. It suddenly occurred to him that if the Huns were trying to lure them out of the city, there was no reason to choose to attack them from the north, and wouldn't it seem more reasonable to attack them from the south?

Could it really be as Qiu Shi said, reinforcements are coming!

Attacking the Huns from the north seems impossible, but if it is replaced by one person, it may not be impossible! You must know that in Mobei at the beginning, there were not many miracles he created.

Cold sweat slowly dripped down his forehead, and Wang Jing twisted his somewhat stiff neck with difficulty. He felt that Qiu Shi was looking at him anxiously, waiting for him to give an order, but he didn't dare to make a decision easily, because the lives of more than 300,000 people in the city were in his hands. He swallowed heavily, his dry throat aching, and lowered his head and closed his eyes in contemplation.

Finally, he raised his head and said calmly; "Pass on our military order, assemble the left and middle battalions, and prepare to go out of the city to receive reinforcements. Let Ding Feng take the right battalion to the city head to be on guard, unless I personally return to the city, I can't open the city gate under any circumstances. ”

"No!" Qiu Shi replied heavily, and went down the city wall with excitement on his face to convey the military order.

A quarter of an hour later, an army of 40,000 men was assembled, and before dawn came, they went out of the city and launched a fierce attack on the Huns.

The Huns were just some scattered early warning cavalry outside the northern city, and when they saw the Qin army suddenly coming out of the city, they immediately turned around in panic and ran. Wang Jing's army quickly tore through the Xiongnu cordon, and rushed towards the Xiongnu camp in the distance, and the journey was surprisingly smooth, and there was hardly any decent resistance.

This also made Wang Jing a little worried that it was a trap, but it was too late to return to the city at this time, so he could only continue to rush forward.

Fortunately, when he rushed to the Hun camp, the worry in his heart was dispelled.

From a distance, the Xiongnu camp for several miles had already become a sea of fire, and the sky-high fire illuminated the dark night as if it were day. Under the light of the fire, the two armies are fighting desperately. Wang Jing had already recognized that the banner of the army that was attacking the Xiongnu camp was the Heishui Qin banner, and he was immediately overjoyed, and hurriedly led his subordinates to launch a fierce attack on the Xiongnu from behind.

When Han Xin's troops arrived at Yanmen, it was already late at night, and he ordered the whole army to rest for an hour, and launched a fierce attack on the unsuspecting Xiongnu army before dawn. Because once the sky became brighter, his army would be exposed to the Huns' field of vision and lose its suddenness, and only a sneak attack could be most effective when the Huns did not find them.

The Qin army's iron cavalry quickly inserted into the unsuspecting Xiongnu camp and hacked the Huns to death while they were still asleep. When Helian Shan was awakened, the Qin army had already broken into the camp and was burning everywhere, while his soldiers fled in panic.

Helian Shan deserves to be a veteran, and after a period of panic, he quickly calmed down, decisively abandoned the already chaotic North Battalion, and hurriedly assembled the soldiers of the South Battalion with his own soldiers to counterattack back. After all, the Xiongnu were outnumbered, and the Qin army was exhausted after many days of running and the whole army was exhausted, and Helian Mountain gradually gathered and actually stood in a position, and the Qin army that entered the camp was mixed up.

The attack launched by Wang Jing from behind completely crushed the resistance of the Huns, and the panicked Hun cavalry turned their horses' heads and fled for their lives like headless flies.

Wang Jing stopped a reinforcement who was fighting and shouted excitedly; "Brother, where did you come from?"

The Qin Jun replied loudly; "We are from Xianyang, I am Yulin!"

Wang Jing was overjoyed when he heard this, and he almost laughed out loud. The reinforcements from Xianyang show that the Qin State is still there, the old Qin people are still there, and there is still hope for the Qin State!

"Who is your commander, I am Wang Jing, the right general of the Northern Army, and I ask to see your commander."

"It's me." A group of men and horses came in response, and a cavalryman surrounded by the Chinese army answered. The blazing fire reflected on his handsome face, and he was looking at Wang Jing with a smile.

"I said I'd come to the Northland to meet you, but it's just a little late."
