"I saw that the grass in the ditch was not there, it was too green, and it was different from other places. Some of the turf outside the ditch is shallow and low, and the green is shallow, and there seem to be traps here. The grass outside the ditch is unusually green, and the swamp is also. Thou shalt not know the reason for this, and thou shalt go by this, and thou shalt go and never return."

All the lieutenants nodded yes, and some of them were in a cold sweat, glad that they did not rush to plunder. Ouyang Xuan took a few personal soldiers to go around along the mountain beam for half a circle, and finally found that the grass in the ditch was a little abnormal, the difference was very small, but the grass roots were slightly raised, if it weren't for Ouyang Xuan's good eyesight, I'm afraid it would be difficult to see. He took out his crossbow, wound it, released a normal crossbow arrow, and shot it at the very edge of the anomaly when no one was around. The distance is eight hundred steps, and Ouyang Xuan uses a curved shot, which does not need to be precise, as long as the shot is good. In the telescope, the crossbow bolt was only half of the shaft, and it was shaking there, and it seemed that there was a ground underneath. Return to the position you just observed, and order everyone to get on their horses and prepare for battle.

Ouyang Xuan led everyone from a valley horse road into the pasture, the horse was not fast, and he bypassed the abnormal area outside the ditch and took the lead in the passage he had just investigated. The swamp here is not deep, only the horse's hooves are not high, and they touched the ground, and the soldiers behind drove the horses in parallel along the range demarcated by Ouyang Xuan. Ouyang Xuan did not rush to charge, but asked everyone to stop, and shot the Huns who were rushing over with bows and arrows, no matter what the woman was, they all shot and killed. Dismounted and looked closely at the ground, and saw a lot of rope mixing. He took out his short knives and broke them one by one, and ordered the guards to carefully remove the ropes and clear the passage before letting everyone rush in. The next thing is almost simple, the people who can go up to the mountain are young men and herdsmen, and those who resist are killed on the spot. Women and children will be let go as long as they do not resist. Only two people were killed, and all the Huns of this pasture surrendered on their knees. Under the authority, the owner of this family pointed out the defensive measures everywhere to Ouyang Xuan one by one, and the more he looked down, the more frightened the captains became. If you don't know it in advance, it's a dead place, enough to withstand the onslaught of 10,000 people.

Ouyang Xuan carried the looted supplies, cattle and sheep, and returned to the camp in the evening with the rescued Han and Donghu herdsmen. For the Huns, Ouyang Xuan chose to leave some cattle, sheep and grain for them to live. For unarmed civilians, Ouyang Xuan didn't want to kill him, because he believed in karma, and the murderer would eventually be killed, and the cycle of heavenly principles would be followed. With these people, he plundered another noble ranch in the same way, and Ouyang Xuan, the ranch of the commoners, forbade the soldiers to go, and also forbade them to loot, just threaten from a distance from afar. The cattle and sheep of all the civilian pastures in the vicinity are not as much as half of the noble pastures, and it is unreasonable to plunder. There is no burden at all on how many people Ouyang Xuan kills on the battlefield, but for civilians in the war, Ouyang Xuan is deliberately protecting, this creed Ouyang Xuan has always abided, with only one exception, that is, the later Shan Yu Yizhi, that is, the current King of Zuogu Li, who had just been killed by Ouyang Xuan and fled in a hurry with 20,000 people.

In the next few days, Ouyang Xuan plundered more than ten aristocratic summer pastures with the cooperation of Tanma, obtained nearly 5,000 cattle and tens of thousands of sheep, left 2,000 cattle and 5,000 sheep, and slaughtered all the others. These herdsmen could only temporarily follow the army and do some logistics and herding work. If they are allowed to return to their hometowns on their own, they will only die on the way home.

When all the materials from Zhuoku arrived, it was half a month later. This time, at Ouyang Xuan's request, Nie Ping brought a thousand stones of cornmeal, and a total of 50 truckloads of various types of explosives and ammunition were transported. Only a hundred carts of bows and crossbows were transported, enough for each person to have a hundred. With these materials, Ouyang Xuan re-planned the route of the march on the map, taking advantage of the fact that the Huns were all in the summer pasture, which was the best time to attack the gathering point of the princes and nobles. Ouyang Xuan's personal scouting reported that he had found the location of the Middle Royal Court and found several royal gathering places. The whole army was ordered to set off tomorrow, and the logistics were still Sima La's four-wheeled carriage.

After finishing the meal early the next morning, under the guidance of the pro-soldier Tanma, carrying the logistics materials, the team of men and horses went straight to the Zhongwang Court at a speed of seventy miles a day, which is also the residence of the Xiongnu ready-made prince and the king of Zuogu Li, in the period of Mao Dunshan Yu is the court of the evil king, and then moved to the current Zhangye area and merged with the original tribe left by Wusun. The evil king in history was almost killed by Yi Zhi Xian, and later killed the defeated King Xiu Tu led some tribes to surrender to the Han Dynasty, and the rest of the tribes were Yi Zhi Xian far away to the bitter cold land in the northeast, which was the place of the later Muwei people, and the king of Xiu Tu was defeated by Huo Quai. Ouyang Xuan's arrival changed this link, but his personal fate did not change.

After crossing two mountains, plundering several noble pastures, and after ten days of running, I finally saw the dense wooden houses and mud houses in the distance, as well as the high king's account. There were also small groups of Huns who kept harassing them along the way, and the result was that the whole army was wiped out. The cavalry of the two flanks gave full play to the level of training, and the tactics of the later Cossack cavalry, such as cross-covering and charging, double team blocking, and knife and bow coordination in the cluster, were vividly played. Along the way, nearly 20,000 Hun troops were wiped out. The army did not slow down in the slightest, and even arrived at the designated position ahead of schedule.

At this time, the Zhongwangting was a herdsmen's settlement similar to that of later generations, and he was not the same as Shan Yu's royal court, that was a castle that moved back and forth, and went back and forth with the Lihou Valley and the Wolf Juxu Mountain, which was formerly called Lushui on the Krulun River in Mongolia, and went back and forth every two years. At this time, Yi Zhixian was still young, and could only be used as the assistant of the prince Yu Dan, to be the king of Zuogu Li, after the wings were hardened, coupled with the blow of Emperor Wu of the Han Dynasty, instead of his uncle, he went to the southwest of the royal court to do the right valley Liwang, and the king of Zuogu Liwang also moved to the lower reaches of the Selenge River basin in Mobei, "Xionghuo grassland", that is, one of the three major clans of the Xiongnu, in the territory of the Xubu clan, and the army of the Han Dynasty has never been touched in history. The Middle Royal Court was abolished and merged with the Shan Yu Royal Court. In history, the Mo Nan No Wang Court refers to the Zuogu Liwang Wang Court on the Hulunbuir grassland, and the other royal courts are in Mobei. The Xiongnu crossed the desert once every nine years to come to the court of the king and worship the gods (the records of the Book of Mountains and Seas should be Emperor Yan). The Middle Court is also the most special existence. Before the first year of Emperor Jing, it was a royal court governed by two kings and was most deeply influenced by the Han land, and it was also the royal court closest to the Han land. As for the Aries royal court, it is the royal court of the outer clan.

Ouyang Xuan ordered the logistics soldiers to line up at the back of the formation, guarded by a group of foot soldiers and his own personal soldiers, and commanded by Shan. The rest of the army were all lined up ten miles outside the royal court. According to the regulations of the battlefield march, move forward slowly. The royal court is different from the summer pasture and the spring and autumn pasture, because there are many people who come and go, no one dares to attack the royal court, except for the elite army, there are basically no other defensive measures (here to explain, the so-called nomadism, is not the kind of nomadism that has no fixed residence, but in the mountainous summer pasture, spring and autumn pasture and winter pasture back and forth, to ensure that the grass in the grassland has time to recover. Not overgrazing, this is a way for nomads to protect the grasslands, which are described in detail in cave petroglyphs, at least for thousands of years. As for the Central Plains history books, living by water and grass is an extremely wrong understanding of not understanding nomadic life. In ancient times, the choice of yurts and grazing pens for summer pastures and spring and autumn pastures was near swamps, or swamps were artificially made with stream water for defense. Of course, this is not the case anymore. The place where this method is still kept is in a place called Mamyasa in Altay, mainly for bear prevention, but it is not very typical anymore).

I don't know what went wrong inside the royal court, the military formation of the Yulin army has been pushed to a mile away, and you can see the Huns who are captive and fleeing for their lives, and they haven't seen any army to meet them. Ouyang Xuan ordered the army to stop advancing, and brought five hundred cavalry directly into the royal court, except for the fleeing Huns, there was no resistance at all, and there was no abnormality. Ordered to inform the cavalry behind to enter the royal court as a whole, and the foot soldiers surrounded the royal court as a unit.

Ouyang Xuan was the first to enter the king's account, empty, and ordered someone to arrest a nobleman for interrogation, only to know that the crown prince Yu Dan and the king of Zuogu Li had led their troops to flee north a day ago. Now the middle royal court is an undefended place, and the whole army is ordered to enter the royal court, and it is strictly ordered not to harass the civilian Huns. But he was not so polite to the nobles, in addition to rescuing the herdsmen, he also had to loot property, cattle and sheep, and if he disobeyed, he would be killed. He also ordered the cavalry to pursue a radius of 300 miles with a team of 1,000 people, and those who could escape at this time were nobles. The foot soldiers were responsible for security precautions, and there were now less than 5,000 poor Huns in the entire royal court, and the chief secretary Dou Pengzu ordered a part of the cattle and sheep plundered by the nobles to be distributed to these people according to their heads, so as to appease the people. The horses from near and far and the horses of the soldiers were all released. For the pro-soldiers and horses he has trained in the past five years, Ouyang Xuan is extremely relieved. They were all trained according to the methods and methods of the scouts of later generations, and these thousand personal guards were now the trump card in Ouyang Xuan's hands. Their families were supported by the Hou Mansion until they retired at the age of 40. Ouyang Xuan also did some experiments during the training of these people, and after drinking Jinshi water for five years, he made a qualitative leap in terms of physique, reaction and strength, and the students of other institutes were the same.

The whole army rested and trained in the royal court, and sent 800 li to report to the imperial court urgently. At the same time, the Yulin was divided into 5,000 people and went out hunting, targeting the nobles and the royal family, and the captains were in charge. At the same time, each team has an interpreter to publicize to the civilians: this place is occupied by the Han family, and a city will be built here, and those who return to the Han family will live unchanged, and those who refuse to carry out will be expelled from Mobei, and those who resist will be beheaded.

A few days later, after the return of horses and cavalry from all sides, less than 20% of the nobles of the Zhongwang Court who fled were scattered, and almost all of the rest were looted and hunted, and countless cattle and sheep were obtained. Shan Yu Prince and Zuo Gu Li Wang fled to Mobei Shan Yu Wang Court, Ouyang Xuan did not plan to stay here, and now the vicinity of Zhongwang Court is already a military vacuum. Ouyang Xuan sent troops and horses to build a city here to control this area. All the rescued Han herdsmen were placed here, waiting for the imperial court to send troops to take over the place.

This was more than half a month, and in the blink of an eye, it was already July, and the troops and officials sent by the imperial court came to take over. The official sent was a Xiongnu general, and it was also placed under the management of Yunzhong County. After handing over the replenishment of supplies, the army continued to clear the grassland along the mountain range to the north and east, and by the time the winter of September came, the army had marched to the western Liaoning region. Along the way, Ouyang Xuan still adopted the policy of purging the aristocracy, and the Xiongnu soldiers in the eastern foothills of Yinshan Mountain to the western Liaoning region were cleaned up, killing nearly 80,000 Xiongnu soldiers. With the advent of winter, the herders have changed their fields, the land has begun to freeze, and the clearing speed has gradually accelerated. Every time a place is cleared, the imperial court will send people to garrison, and all the people who come are Xiongnu generals. He was a marquis in this place, and the imperial court sent troops to be stationed there.

In this purge, the Yulin Army did not encounter any decent resistance, it was all the resistance of some small tribes, and at most it was a small-scale harassment of 5,000 people. Under the guidance of Ouyang Xuan, these captains have a very detailed understanding of the nomadic life of the grassland, and even cracked the meaning of the Lushi rock painting symbol through the surrendered Huns, and they have been able to lead the troops to fight and clear it alone, which has made Ouyang Xuan a lot easier. With the onset of winter, a key issue also arises, which is winter clothing. As for the lack of food for the time being, the plundered cattle and sheep can survive the winter. The reason why Ouyang Xuan wanted to march so far was to completely solve the main force of King Zuo Xian and reduce the threat to Yan and Liaodong. He has been sending scouts to find the main force of Zuo Xianwang, but he has not seen him for a long time. In mid-September, it traveled to the location of Tongliao in later generations. The army had to stop and prepare warm clothing. This is the territory of King Zuoxian, the people are fierce, and Ouyang Xuan's strategy is to kill and drive away. This is also the place where the main troops of the last attack on Shanggu Yuyang were located. The captured civilians were all driven to the hinterland of Yan to open up wasteland and farm, and later Liu Qi did not know who came up with the idea, and organized an army dedicated to escorting the captives, called the Beifu Army, and followed Ouyang Xuan all the way east through Shanggu, as long as there were captured people, they were escorted to the hinterland of the Central Plains to open up wasteland, and there was no one from Shanggu to Western Liaoning. However, the winter winter clothing of the Yulin Army has not been delivered for a long time, and the logistics supply route here is now very safe. Ouyang Xuan immediately judged that there must be someone in the court who was making a mistake, so he gritted his teeth in anger, and sent a letter to the court urgently, and eight hundred were sent to the court and the middle of the country, but there was still no news at all at the beginning of October. There was no way, Ouyang Xuan had to order someone to slaughter all the captured cattle and sheep, fill the reed flowers with double sheepskin fur to wool, and find someone who knew how to tailor among the rescued herdsmen to make cold leather clothes. In just half a month, tens of thousands of temporary cold leather clothing were made with the participation of all the Yulin Army, this kind of leather clothing without special treatment is only suitable for wearing above minus 20 degrees, and the leather is frozen hard below minus 20 degrees, and there is no cold protection effect at all.

Now the logistics supply has also been cut off, fortunately, Ouyang Xuan has made enough air-dried meat, and set up a long-term camp in the place called the Mulun River by the locals, and the camp tent in the Central Plains region of the alpine region is no longer suitable for the low temperature environment here, Ouyang Xuan ordered people to cut wood to make wooden houses, build mud and stone stoves, mow grass reserves on the river beach, and build wooden houses for the horses to keep warm. Ouyang Xuan didn't dare to be careless, if he encountered the White Calamity, it would be completely over.

When the camp was still under construction, the soldiers and horses hurriedly came to report: "My lord, my subordinates have found out that the Xiongnu Zuoxian King united with the kings of Shan Yubu, the king of Donghu and the king of the Lan clan to gather 300,000 troops, and rushed here along the Xianbei Mountain, according to which there are still 200 miles." "Go and find out again, and closely monitor the movements of the Hun army." "Report, General, North Korea's Wei Shimeng came from the east along the river with 50,000 troops, according to which a hundred miles." "Re-explore and report again".

This Wei Joseon also came to join in the excitement of the gate, which faces the river in the north, equals the land in winter, and is surrounded by empty plains. The generals were convened to discuss with the room, and the two military information and logistics reserves were first reported, and everyone discussed the next step of the operation, and a huge map of the ground in the hall was hung in the bright place. The generals pointed around the map and measured the distance. While the discussion was being held, a man covered in blood appeared at the door of the hall. Entering the hall and kneeling on one knee, "Yu Junhou", Ouyang Xuan, who was looking at the map, looked back, and his heart suddenly cooled, and the feeling of detachment quickly disturbed his whole body.
