Entering the valley, Ouyang Xuan hit his horse and climbed the mountain beam on the north side, holding his sword immediately. Buick and Guli didn't know when to shake off the servants who were guarding them, and squatted next to them at the right time, looking around the battlefield with Ouyang Xuan. On the ridges of the four circles, the artillery was already in full array, waiting for orders. The sound of landmine explosions in all surroundings was incessant, deafening. The Hun soldiers on all sides were still overwhelmed by the old explosion and charged wildly, the explosion never stopped, Ouyang Xuan could see the horses and Huns flying high behind him, and he didn't know how much explosives these guys had added to the arsenal. The power of the lightning explosion was enough to leave no living creatures within fifty meters of the perimeter. The vanguard of the Huns, who attacked the mountain beams on all sides, had to retreat after frantically attacking for half an hour and losing half of their men and horses. Ouyang Xuan admired the rich imagination of the generals Peng Fei and Dai Zhan at this time, the density of mines in ten miles increased gradually, and the front row was very loose, all of them were infantry mines, and the further back they went, the greater the density began to be mixed with jumping mines, and the density reached the maximum at five to one mile from the mountain beam, reaching two to three per square meter. Almost all of them are jumping mines, and the density of mines is not high in the 100 steps of the mountain beam, one per square meter, and they are all a mixture of infantry mines and jumping mines. The Huns have not yet reached the range of four miles and have lost their troops and will have to retreat, the huge casualties did not scare off the Huns, this is the characteristic of the character of the steppe nomads, if the casualties are small, they may choose to retreat, once the casualties are too large, it will arouse the fanaticism of revenge in their hearts, I have to say that these generals have a thorough understanding of the character of the Huns.

Less than an hour later, the Huns on all sides did not attack the mountain beams, but concentrated their forces to attack the valley passes on the south and northeast sides, which was completely carried out as expected. Ouyang Xuan ordered a part of his troops to go to the two valleys to support the two battalions of the Huaxia Army that were feinting and defending, and the other part to reinforce and protect the artillery. Originally, Peng Fei disagreed, but he couldn't resist Ouyang Xuan's strong order. On the entire north side of the mountain beam, there is a bright silver armor, a white horse, and Ouyang Xuan holding a bright silver meteorite sword. and the two white wolves around him who squatted like the Lion King and looked out on the battlefield.

The sound of a series of loud explosions was heard again, and the artillerymen finally began to roar when Dai Zhan's sword fell. The Xiongnu vanguard army, which was already charging intensively, suffered an even more brutal blow this time. Only 20,000 of the 100,000 Hun vanguard rushed through the five-mile death zone to reach Yuanmen, and the rest were either howling in pain on the ground or had already returned to the sky. Under the cover of their own soldiers, the Huaxia troops in the two gates gradually retreated to the artillery positions to assist in the protection of the artillery.

After the Huns who rushed into the valley found that it was very safe, the 200,000 main forces of the Huns continued to enter the valley through the safe passage that the vanguard troops had just passed. When the Huns finally finished entering the valley, the green flag in Dai Zhan's hand on the east side of the mountain beam was raised high. All the soldiers on the mountain beam, including their own soldiers, picked up their hair ropes and stared at Dai Zhan. Just when the Hun soldiers were still wondering, the green flag fell. The Chinese soldier pulled the hair rope in his hand hard, and the power on the rope was transmitted to the mechanism on the mine through the bamboo pipe buried in the ground, and the safety was opened. In an instant, explosions sounded one after another in the valley, and the artillery turned the muzzle, aimed at the valley according to the pre-demarcated area, and once again let out an angry roar, and the density of mines in the valley was not small, and they were all arranged in two steps in a square circle. In addition to the mines that pull the hair rope, there are also chain mines that open multiple mine fuses when the mine jumps into the air, and there are also mines that open the safety when the rope is raised. At the same time as the shells fell, the trebuchets on the mountain beams, which had not been used for a long time, threw cans of light oil into the valley, followed by more brutal incendiary bombs. This kind of joint attack reminded Ouyang Xuan, who was watching the battle on the mountain beam, of the Opium War in later generations. In less than half an hour, the valley was already full of fire, the air pressure dropped suddenly, and a strong wind blew on the mountain beams. Taking advantage of the wind, cans of fire oil were once again thrown into the valley, and the place that could hold 500,000 people became a hell on earth in an instant. Everywhere there were screams and the screams of horses. The people who were still alive, under the organization of a general, escorted Yi Zhi diagonally towards the mouth of the southern valley and quickly retreated. There were also generals who organized their soldiers to charge on the mountain beams, but before they reached the mountainside, they were less than one in ten. The high temperature and lack of oxygen made the more than 200,000 Hun soldiers in the valley miserable, and countless suicides were committed. Ouyang Xuan couldn't bear to see this scene on the north side of the mountain beam, and waved his sword to signal to stop the oil throwing and shelling, these were enough, and there was no need to continue to implement the following means. Dai Zhan also felt the same way, and after seeing Ouyang Xuan's signal, he ordered to stop further action. I just silently watched the miserable scene in the valley, and imagined what it would be like if I pushed the rolling logs full of nails down the valley, and also thought about what kind of miserable scene it would be if I threw the explosives bag. On the south side, Yizhi still led less than 50,000 people to escape from this hell on earth under the multiple blows of mines, bows and arrows, and cannonballs, and retreated to the Shan Yu royal court.

He Toad, who was originally intercepting through the cave on the periphery, was called back, and only Huyan Leopard led 10,000 soldiers and horses to raid the Chechen Khan. It was the morning of the next day when the fire was completely extinguished, and the soldiers were ordered to re-install the unexploded mines layer by layer according to the map of the mines. It was easy to bury mines, but it was difficult to dig mines, and it took twenty days to dig mines and clean up the battlefield, and the seriously injured Hun soldiers who were burned, missing arms and legs, Ouyang Xuan ordered them to die happily, and actively treated those who were slightly injured. After clearing and lying down with the herd once to make sure there are no more mines, do not stop.

The Huyan leopard raided the Chechen Khan without even fighting, and the entire valley was already empty by the time the army arrived. After obtaining Ouyang Xuan's consent, he took 20,000 people to clear the Huns on the east side of Gonglushui. For reasons of their own clan, these people trusted Huyan Leopard and the two battalions of the Xiongnu army under his command.

When Ouyang Xuan's soldiers arrived in the royal court, they also went to the camp. Lost belongings, all over the floor. Ordered to call for the leopard to be carefully sorted, the useful ones were classified and returned to the library, and the useless ones were burned. Entering the single king's account, Ouyang Xuan's eyes were hung on the left side with a dongbula and two short knives with leather sheaths. There are also several bone drinking vessels with gold trim on the table. He took off the tombra and the short knife, stroked it lightly with his hand, and stared at it for a long time, and a tear gently fell on the hilt.

"Come on, bring the captured Yizhi slanted guards up", Ouyang Xuan said fiercely with red eyes and two tears on his face. These generals under him faintly felt a chill. No one knew why Ouyang Xuan, who had always been iron-clad, saw these two items like this, there must be a story behind this, but no one dared to ask.

In a few moments, two well-dressed Huns, one with their arms hanging and one with bandages around their legs, were brought into the royal tent with which they had once been familiar. The two of them, supported by their own guards, leaned down to salute. "I ask you, where is the owner of these two things?" , Ouyang Xuan spoke Xiongnu directly. The two of them looked up at Dongbula and the two short knives, "Back to the big head, Dongbula was originally owned by the Wusun Hanhai Yunyou Poet, and he often sang praises for the exploits of the divine envoys back then. Those two knives belonged to Queen Dawan. Last autumn, when he sent an army to the Western Regions, Da Dan heard that a poet praised the divine envoy, so he captured him, killed him and fed it to the wolves. When we attacked Dawan, Queen Dawan resisted to the death after the death of King Dawan, and was finally captured.

"Since you are Yi Zhixie's personal soldiers, who will die if you kill these two people?" , Ouyang Xuan said in a very calm tone.

"The people who go back to the big head are all done by our own soldiers."

"Do you know who I am? What does these two have to do with me? This sentence came out in a tone that was almost extremely angry, and almost gritted his teeth to say it.

"I only heard Da Shan Yu say that the big head people have had experience in the Western Regions, and I don't know anything else."

"Tell you that the owner of this Dongbula gave him the art of piano and song forty years ago and gave this thing. Queen Dawan is my confidant forty years ago, and she is the savior of my mother of white wolves." Ouyang Xuan's eyes were on fire, if his gaze could kill, these two people would have been dead for an unknown number of times, and said hatefully.

The guards found the white wolf, stroked the wolf's head, stared at the two people in the tent, patted Gu Li's head, and pointed to the human head wine vessel on the table, Buick and Gu Li seemed to understand something, stepped forward and sniffed one by one, wailing in front of a head wine vessel, the familiar smell forty years ago aroused their childhood memories. Ouyang Xuan picked up the wine vessel and stroked it lightly for a while. None of the people below dared to speak out, and they all looked at Ouyang Xuan silently. After a long while, he said slowly: "Come on, pull these two out, kill all the captives, and leave these two to my wolf king." After speaking, he patted Buick and Guli on the back, and pointed to the two Huns. Buick and Guli got up and left the desk, paced in front of the two, bared their teeth, showing sharp teeth, and a fierce face. The two men dragged by the guards went out of the king's account.

"The order was given that the whole army rested for five days, and the other generals except General Huyan led the men and horses of the headquarters to slaughter the tribes of the Xiongnu headquarters in the north of the desert, regardless of men, women, old and children. Five days later, General Huyan was ordered to be the main general, and Captain Peng was the deputy general to lead 40,000 horses and horses, and carried artillery battalions to raid the territory of King Youxian. The other generals will be cleared after this break. Ordered you to return to this place as soon as the mission is completed, and follow me to the Beihai expedition and kill Yi Zhixiao." "No!" , The generals got up to receive the order, and began to study how to raid the Right Xian King in front of the map At this time, there was a terrible scream outside, the scream was terrible, and it took a quarter of an hour to stop, Buick and Gu Li walked into the tent with blood on their mouths and claws, and snuggled up to Ouyang Xuan's side, like a martyred doll, * with blood stains on their fur. Everyone didn't see it, and they were still discussing in front of the map how to attack the Right Sage King. After a long time, the horses everywhere reported one after another, and after the defeat of Yizhi Xian, the king of Youxian led his tribe to bypass Yanran Mountain, go to the salary plough department, and converge with the defeated department of the Xiongnu in Beihai, leaving behind all the small tribes of vassals.

For the escape of the right Xian King, it did not exceed everyone's prediction at all, first the right valley Li Wang followed Yi Zhi to flee to Beihai, and now the right Xian Wang also fled north, and there is no longer a threat to the Xiongnu tribe south of Beihai. According to the report of the horse visit, Ouyang Xuan immediately ordered the cancellation of the previous order, and used Shan Yu Wangting as a base to clean up the Mobei Buchen forces in a month. Repair a letter to the prince, ordering him to prepare Xiongnu officials, build city materials, and build a city across the desert. The construction of a railway connecting the south and north of the desert began. This plan has long been in place for the imperial court, and as early as before the army set off, it had already reserved enough materials and personnel in Hanyang City (now Erenhot City of Xilin Gol League) in Monan, and only waited for Ouyang Xuan to pacify Mobei, that is, to start building the city and building the railway.

It's May, and there are still some dangers in sending troops to the North Sea, and the best time is from June to September. After the order was given, everyone carried out the order in an orderly manner, and only a few small tribes were left in their own clan, and under the persuasion of the generals, Ouyang Xuan canceled the idea of slaughtering the clan. But there is also a word first, and there is a person who does not surrender, slaughtering him. The speed of the purging was very fast, so fast that everyone was a little unprepared, but after clearing a few tribes in the headquarters, the remaining tribes in the territory of King Youxian and Liwang of Right Valley and other small tribes in the south of Mobei directly sent people to ask for surrender. I had to send Huyan Leopard to lead 10,000 soldiers and horses to patrol around, divide the spring, autumn and summer pastures of each department, and choose a suitable location for building the city.

According to the original plan, it will be the future Mengzhou of Huaxia Kingdom, with six counties and seventeen counties. It was not an easy task to choose this kind of location and build a city, so I had to wait for Xia Gu to send troops and officials to receive it. Taking advantage of this gap, a special training was conducted for operations in mountainous areas.

In June, the weather has entered a hot and dry season. The officials selected by the prince followed the 100,000 Huaxia army across the desert and entered the desert under the scorching sun, and the leader was one of the few Qiang people in the new generation of generals, Bai Yang Lone, who was a Qiang orphan who was cultivated since childhood, and was also among the best among the new generation of generals. Mengzhou's Thorn Shi Xu Bushou is a Huns, the son of a shepherd slave, and Huyan Leopard, he has received education in Huaxia since he was a child, because he loves to study, he served as the vice president of the Ministry of Industry Research Institute, and his ability is also outstanding.

After the handover was completed, Ouyang Xuan ordered the whole army to be reorganized, and five days later, the whole army went north and killed the remnants of the Xiongnu Shan Yu.
