According to the topography, the guide's description, compared with the map, this should be the hilly area near the Mongolian Choibalsan in later generations, the Huns called the local Gonglu Mountain because of the Gonglu water passing through this place, according to the deer stones and petroglyphs along the way, it is a winter pasture. Ouyang Xuan judged that the altitude here should be around eight hundred meters based on the air pressure. In later generations, Ouyang Xuan had been here and still had some impressions of this place. He ordered his soldiers to go to Gonglu Mountain to find a cave (on the northeast side of the later Mongolian Choibalsan City), where there were some murals that Ouyang Xuan had been looking for since he came to this era. His impression should be related to aliens and five-dimensional space.

In this era, the lowest temperature in winter will be minus 40 degrees, and the camp is made of ice and river water, trees, sand and gravel, and tree branches from Gonglu water, and is ten meters high. 50,000 people can be made in just two hours. The outside is an eighty-degree slope with steps on the inside and sand on the walls. There were no tents, but manholes, and in groups of five people, a deep pit was dug for one person, which could sleep five people, and a flat cover was tightly built with wood, and then covered with thick gravel. This is a desert area with very little topsoil moisture, so it's easy to dig up. A tent was erected next to the manhole to serve as an entry and exit and an exit from the chimney. In the evening, after the camp was settled, Ouyang Xuan inspected the light and dark sentry posts and the horse traps and mines on the periphery of the camp before ordering to bury the pot and make food.

For this Chinese army that penetrated deep into the north of the Xiongnu desert, the Huns did not have the slightest sense of fear, after all, they occupied the land and people. This trusted Zuo Xian King is a son of Yi Zhixian, Zuo Gu Li Wang is the son of the original Zuo Xian Wang, the two of them were ordered by Yi Zhixian to lead the headquarters of the men and horses here to intercept the only 50,000 Chinese army, they are still confident, no other day is too cold, dripping into ice, go out to pee have to bring a stick in the weather, people living in the south of the desert are difficult to adapt, and then there is the terrain here, the north is high and the south is low, the ravines are vertical and horizontal, for outsiders who are not familiar with the terrain, they will fall into the ravines and die if they are not careful. When the Tanma sent out reported that the Huaxia Army was stationed in the valley plain under the mountain, the two looked at each other and smiled, and in the conference hall built of wood, Captain Zuo, King Huyan and the commanders of the 10,000 people were all relaxed. Flowing westward along the foot of the mountain, the Gobi Desert is open to the south, and the hilly area of the Gonglu Mountain is gentle to the north, and 100,000 cavalry can break through the camp with a single charge from the shallow ridge of the Gonglu Mountain.

The Huns did not choose to attack at night, because they could not stand the bitter cold of more than minus forty degrees at night. When the sun rose at an angle of 45 degrees, there was still silence in the Huaxia military camp, and there was no sign of anyone on the ground except for piles of sand and gravel piles and tents next to it. Standing on the mountain beam, King Huyan said worriedly: "The camp of the divine envoy seems to be weird, I am afraid that there is an ambush, don't forget the sneaking camp battle of Subuzaland back then, the god of the gods used soldiers, and we cannot defeat it." "What King Huyan said is extremely true, the camp is so quiet, there is indeed something different, and the order is to return to the valley of the army, and the Captain Zuo will leave a team of 1,000 people to monitor the army of divine envoys." After listening to King Huyan's analysis, King Zuo Xian ordered the withdrawal of his troops.

Until nearly noon, the camp of the Huaxia Army was still calm as usual, except for the guards on duty who entered and exited the camp tent, and no one could be seen. Ouyang Xuan's order was to rest and recuperate today, and the whole army should eat and sleep well in the manhole. The Huaxia soldiers, who were full of confidence in the non-human defense of the periphery, were very calm, and after they were full, they got into a warm sleeping bag, covered their heads and slept soundly, and the horses everywhere reported the enemy situation to Ouyang Xuan one after another.

It's not that Ouyang Xuan used any tricks, it's just a coincidence, entering the hinterland of the Mongolian Plateau, the soldier's body has not fully adapted to the drought here and the winter pressure here. Although the Mongolian Plateau is not high, the winter pressure here is extremely unstable in Mobei due to the influence of the cold high pressure formed in the winter of the northern polar region and the Siberian Plateau cutting off the polar low pressure. When the high pressure moves south, the air pressure will rise, and when the high pressure is formed, the air pressure here will be driven by the formation of the high pressure to form a relatively low pressure, which is equivalent to the air pressure above 2,000 meters above sea level. It is also the cause of winter snow in the semi-arid areas here. When I woke up in the morning, judging by the wind direction and barometer, I saw that there was a high pressure forming in the north. The soldiers were a little uncomfortable with this gradually decreasing air pressure, and reacted to varying degrees, so they ordered all of them to rest. If the Huns launched a charge at this time, once they broke through the unmanned defenses on the periphery and entered the camp, the combat effectiveness of the Huaxia army would also drop a lot. At the beginning, Huo Qubing sent troops to Wolf Juxu Mountain, which was not far from here, and it was also for this reason that he had to close the mountain and return, and he could no longer attack Shan Yu Wang Court to the northwest, and it was only a thousand miles away from Shan Yu Wang Ting. It is also the reason why the Han army was unable to break through the 48th parallel in the end. Only to the Xiongnu Sanshan Desert Base. The cross-desert base is located in the south-central part of Mongolia, which is a plain valley surrounded by three mountain ranges named Zhenyan Mountain, Junji Mountain, and Zhuotu Mountain, and it is also the place where Wei Qing and Shan Yu fought the main force in that year. Influenced by the perception at the time, the Han army ultimately failed to completely defeat the Xiongnu.

It took ten days for the Huaxia army to gradually adapt to the changes in air pressure here. Every day, Ouyang Xuan sent a good state of soldiers to regroup, led by Huyan Leopard, to attack the Huns who were monitoring. Heavy snow came suddenly during the night as the depression ended, and the snow was so heavy that it was beyond imagination. It is very different from the snow in Jianghuai, it is also heavy snow, here with strong winds, the temperature outside will reach more than minus 40 degrees, and the wind blowing snow is the most dangerous existence in the storm. Huaxia camp is located in the river valley plain, belonging to the front of the wind downhill wind, the wind mixed with goose feathers and heavy snow blows through the camp and continues to blow south for five miles to land. On the sunny slope to the north, the snow blows up from the shady slope, and it is very soft.

Ouyang Xuan ordered the people to continue to strengthen the ice wall of the camp on the north side of the camp, and the slope increased to 60 degrees, and the height increased by ten meters. Each manhole was made of mud and stone with a double chimney and a ventilation duct. The horses from near and far returned to the camp one after another, but Ouyang Xuan did not let them go out again. Under such meteorological conditions, it is difficult for any living creature to survive in the wild. It's warm like spring in the manhole, but outside it's cold with a snowstorm. The Huns live in this climate all year round, and naturally have their own ways of coping, so their winter nests are all silk cotton or valleys surrounded by mountains on three sides, and will not choose plain river valleys. Just like the place chosen by the current Zuo Xianwang is a valley surrounded by mountains, the wind is blocked by the mountains, mixed with snow storms in the sky, and falls to the ground on the other side of the shady slope, forming a hard snow shell with wind blowing snow, which is hard enough to stand a few horses, this is the common snow and ice in the winter of the Mongolian Plateau and the Siberian Plateau before the Middle Ages, and there are many snow and ice relics of this era in the mountains of the northern part of the Republic of Tuva, Russia, which are different from glaciers, which are formed by the compression of snow under the action of the wind. At the beginning of spring, it was covered with sand and was swept up by strong winds, and it was preserved.

After two days of the violent snowstorm, all the horses released returned, everyone had more or less frostbite, and after emergency treatment with Jinshi water, Ouyang Xuan decided to go out to reconnoiter with two personal soldiers, all armed. Whether it was a soldier or a general, no matter how he persuaded him, Ouyang Xuan would not let people go out of the camp again, and had to go out to investigate by himself. It's not that Ouyang Xuan wants to show anything, but he has to do it. First, it is very dangerous to have no hostility in an enemy country; The second is that other people have no special training in this vicious environment, and it is easy to have non-combat attrition, which Ouyang Xuan does not want to see. Although he has left the special forces for more than 40 years, he has never given up training over the years, and he still insists on winter swimming every year, exercising in the wind and snow, and working in the flood.

After comforting everyone, he chose two personal soldiers who had trained with him, put on thick equipment, took Buick and Guli, walked out of the manhole, and entered the tent. After acclimatizing to the temperature, he stepped out of the tent and plunged into the snow. Although it was noon, the sky and the earth were chaotic, and the visibility did not exceed ten meters. There is no horseback, only walking, and in this weather, once the horse is out of the protection of the manhole, the strong wind will quickly take away the body temperature, causing hypothermia and freezing, becoming an ice corpse. The three of them were all dressed in white clothes and hats, wearing goggles, and Ouyang Xuan had his own special assault rifle in his hand, a sword and a delicate golden alloy imitation M1911 pistol and the crossbow arrow in his waist. The weapon in the soldier's hand was a semi-automatic rifle, and he carried a steel saber at his waist, a pistol imitation of the M1911, and a crossbow arrow. In this kind of place with very low humidity, one of the most beneficial things for thermal weapons is that firearms are not afraid of freezing. Each person had a thick backpack containing two days' worth of dry food and a down sleeping bag and made his way west along the leeward mountainside. Although it is only less than 60 miles, the journey is quite difficult, and if it weren't for Ouyang Xuan's rich outdoor experience, it is estimated that he would freeze in the wind and snow because of the snow in his shoes. Before leaving, three makeshift snow suits were made out of tarpaulin, steel crampons with road spikes on their shoes, and each person had a makeshift walking ice axe in his hand, and the snow was knee-deep even when it was leeward.

In the vast white world, there is chaos, it is impossible to distinguish where is the sky and where is the earth, the wind rolls up the blizzard and blows almost flat to the south, only at dinner time to walk out of less than twenty miles, find a cave, three people and two wolves simply eat some air-dried meat, extinguish the torches, arrange to take turns on duty, only then get into the sleeping bag, take a nap. The wild in this kind of weather is still full of dangers, hungry wolves, snow leopards are all dangerous existences, especially nocturnal beasts in the downwind location. No, it wasn't even midnight, and the soldiers on duty woke everyone up. As the guards on duty came to the entrance of the cave, they quickly swept it with their headlamps, and there were some eyes reflecting blue light on the mountainside and snow nests not far away, and there were several on the mountain beams not far away. "It's rare to encounter wolves on this snowy night, and it's a sight to behold." As he spoke, he pulled out his assault rifle, opened the safe, and aimed at the mountain beam in the distance with his scope, but he couldn't see anything clearly, so he could only wait. Buick and Guli also came to join in the fun at some point, and the nature of the wolf made them very excited about this kind of thing, and they ran out of the cave and howled a few times at the wolf in the distance, and the sound carried a kind of majesty and domineering. After howling, he sat in the snowdrift and looked at the mountain beams in the distance. There were also a few wolf howls back there, the same majesty.

Buick and Gu Li got up to run over, but Ouyang Xuan hurriedly called them back with a low whistle. With so many wolves, Ouyang Xuan was afraid that the white wolves in their thirties would not be able to resist, although they were stronger than twenty years ago, they could not withstand too many wolves outside. Buick and Gu Li came back and lay on Ouyang Xuan's side, staring outside. The wind and snow still have no tendency to weaken, the wind is still roaring, and the snow particles blowing up are all over the world. The world passed little by little, and the wolves still didn't move. Ouyang Xuan ordered his soldiers to go to sleep and stared at it himself. Where are these two people willing to do it, in the end, it was Ouyang Xuan's strong order that they got into their sleeping bags.

It wasn't until three o'clock in the second half of the night that the wolves slowly moved towards the cave in the wind and snow, and Buick and Guli also began to be restless. Ouyang Xuan also faintly saw a huge white shadow in the wind and snow curtain. This reminded Ouyang Xuan of a story about a white bear and a wolf painted in a cave near Choibalshan, a young white bear who was adopted by a pack of wolves and eventually became a member of the wolf pack. Crisscross the mountains and meadows with wolves, chasing deer and slaughtering beasts. He became the god of the mountains, and later met a girl during a hunt, and every day he would put the prey at the door of the girl's yurt, and the girl also saved a wolf cub in the pack. On a snowy night, the girl was buried by a blizzard, and the white bear dug it out, and died after a long agony on the mountain. The gods were also moved, and made it a majestic mountain, and the girl turned into a dark blue lake, and Ouyang Xuan deduced that the mountains and lakes in this painting might be Kruren and Hohe Lake, because there are similar legends among the local people.

Ouyang Xuan turned on his headlamp and scanned it, the wolf pack strikers had already reached the attack distance, it seemed that there were at least fifty of them, he changed the assault rifle to a single shot mode, raised the gun to aim, bang, and the wolf pack that was accelerating fell one by one. When the soldiers heard the gunshots, they also quickly got up, picked up their rifles, and knelt down to find the target to shoot.

In less than twenty minutes, there was not a single wolf in the attack range, and it was estimated that at least thirty wolves would have been killed. Several wolves on the mountain ridge in the distance were also gone, and as time passed, Buick and Guli also regained their composure and returned to their caves to continue sleeping. The next morning, I ate some jerky, and did not look for the corpses of the wolves from last night, and continued to march west along the mountain. After walking thirty miles, Ouyang Xuan saw through the scope a line of wide footprints in the leeward part of the mountain beam, as well as bloodstains. In the evening, ten miles away from the Xiongnu camp, the corpses of several dead wolves and Xiongnu sentries were seen, which was terrible. Ouyang Xuan took two people and two wolves, along the ridge by the wind line, found a three-sided cliff nest less than five miles away from the Hun camp, dug up the snow to build a snow cave, and placed the equipment. A cordon was arranged on the periphery, and only then did he go back to the cave, eat some food, and get into his sleeping bag. In the second half of the night, the copper bell connected to the guard in the snow cave sounded an alarm, and Ouyang Xuan got up one by one, holding a well-wounded crossbow, lying next to his soldiers to observe the situation outside the snow cave. The cordon is divided into eight and arranged in eight directions, each of which is connected with a brass bell in a snow cave. Judging by the bell, it should be that there is something at the entrance of the snow cave on the south side that has sent a warning rope, and Buick and Guli are starting to be anxious again, constantly looking out at the entrance of the cave.

It was pitch black outside, and the headlamp was turned on, and there was no light in the distance, after all, it was too close to the Hun camp. With the help of the light reflected by the snow, he could faintly see the situation three or four hundred meters away, "Your Majesty, look, there is something three hundred steps ahead", a soldier reminded Ouyang Xuandao. As the headlamp swept over, Ouyang Xuan's back was a little chilly.
