At the beginning of March 643, after the angelic army crossed the Tanggula Mountain and entered the hinterland of Tibet, it encountered several small battles, which were basically crushed.

On the Qinghai-Tibet Plateau in March, the wind was very fierce, and there were bursts of howling, and the crazy cold wind mixed with snow hail shot at the solemn soldiers, hit them in the face, and rolled down to the ground, which was already two inches thick with snow. Feet on the snow and ice, making a rattling sound.

In the wind and snow on the plateau, the soldiers of the Angel Special Operations Regiment marched very hard, and the mountain tops, grass flats, ravines, and soil bags were all covered with snow.

Zhao Quan led a team of people to open the way in front. Zhao Quan felt that the snow here was exceptionally white, so white that he couldn't believe that there was such a clean thing on the earth, as if the snow had been washed with water, and he felt that the water was not as clean as the snow here. If the snow is washed, it may even get dirty.

Zhao Quan grabbed a handful of snow, and he felt that the snow on the Qinghai-Tibet Plateau was harder than the snow in their hometown. The snow from their hometown is cold and velvety, giving people a very soft feeling. And the snow at an altitude of more than 5,000 meters is extremely hard, like grabbing a handful of cold sand and gravel, and when kneading the snow ball, it makes a crapping sound in the palm of your hand, and the sound is also very hard.

Seeing that it was not early, Zhao Quan set up camp at the observation point. It was a relatively flat grassy beach covered with a thin layer of snow, and they cleared an open space to erect a yurt.

At this time, the eldest grandson queen Xia Xue happened to bring Ouyang Qian and a few people to rush over from the rear on horseback, and the forward pathfinder team led by Zhao Quan was about 6 miles away from the rear army. After Xia Xue asked Zhao Quan about some investigations, she checked around the yurt and said, "It's not warm for you to build a yurt like this." ”

"Your Majesty, why isn't it warm?" Zhao Quan asked suspiciously after saluting the queen.

"There is a leak of air under your yurt, and no matter how big the fire is, it will not work. It is necessary to build a fence with ice and snow on the outside of the yurt to keep out the wind and keep warm. ”

"Your Majesty, you said that it makes sense to use ice and snow to block the wind, but let us sleep in a room made of ice and snow to keep warm, I can't figure it out." Song Erniuzhu held a shovel in his hand and did not move.

"Your Majesty, if you let us build the ice and snow outside the yurt, and we make a fire in the yurt to keep warm, will it melt the ice and snow outside the yurt?" Ouyang Yong was also a little puzzled.

"You are right to do what Your Majesty says!" Zhao Feng took the lead in shoveling the snow.

"The current temperature is more than minus 20 degrees during the day and reaches minus 40 degrees at night, and the freezing point is zero at sea level......

Although everyone was confused, they all knew the magic of the eldest grandson, so they worked hard to build ice and snow outside the yurt. The plateau lacks oxygen, and after a few minutes of drying, I feel chest tightness, dizziness, Venus in my eyes, weak muscles and bones, and roaring ears. Everyone stopped digging in the snow, and with shovels, they gasped for air. After taking a breath for five or six minutes, I went to dig again, and after digging for less than five or six minutes, I had to rest, and the work efficiency was extremely slow.

After more than an hour, the snow wall outside the yurt was erected. Xia Xue asked everyone to pick up a lot of wild yak dung from the snow and light it on a stove surrounded by stones. After a while, the yurt room was full of warmth.

Ouyang Qian saw that it was so warm in this magical ice and snow felt room, and she didn't want to go back to the cold camp of the large army in the rear. She coquettishly told Xia Xue that she wanted to stay in the forward pathfinder team to accompany her brother Ouyang Yong temporarily, but Xia Xue had no choice but to ask everyone to help build a smaller ice and snow felt house for Ouyang Qian.

After Xia Xue saw that there was basically no problem with the camp of the forward pathfinder team, she rode back to the rear of the large army, and in the alpine region, Xia Xue was most worried about frostbite. Frostbite is divided into several grades, mild frostbite, severe frostbite, deep frostbite, death, frostbite to near death is characterized by stiff limbs, loss of reason, inability to speak, and then development is death. Frostbite can lead to a large non-combat attrition of troops, seriously weakening the combat effectiveness of the army.

After Xia Xue returned to the camp of the large army in the rear, he ordered the whole army to build barracks in accordance with the method of the forward pathfinder team. Although it was a bit troublesome to build this kind of barracks, the soldiers who were shivering from the cold almost melted the warmth inside after entering this kind of snow-walled yurt, and they slept under the covers one by one and did not want to get up for a whole night.

The darkness of the night faded, and the sky had a faint morning light. The gray-black snow turned gray, light gray, gray-white, pale white, snow-white, and when you felt the dazzle of the snow, the sky was already bright.

Zhao Quan made a lot of determination to get out of the warm quilt, and after putting it on, he walked out of the yurt sleepily, and the fresh but biting cold air immediately enveloped him. He trembled all over him, and lifted his spirits. As far as the eye can see, there is not a trace of artificiality, and the eyes are full of snow white without any impurities. I couldn't help but sigh in my heart: "It's so clean where there are no traces!" ”

The sky was clear, and the sun, which had been hidden by the wind and snow for many days, came out. The sky was also surprisingly blue, so blue that there was no trace of variegation, as if it had been brushed by wind and snow, and it seemed that the clouds were also surprisingly white, like snow floating on the ground to the sky. The sun was surprisingly round, and the sun shone on the snow, radiating a dazzling light. Zhao Quan felt itchy and painful tears in his eyes, which was a precursor to snow blindness. He took out the sunglasses that Xia Xue had specially issued for this expedition and put them on, and the sky on the Qinghai-Tibet Plateau was much darker, and the itching in his eyes was also reduced a lot.

……

The Angel Firearms Legion continued to advance towards the Tibetan capital of Luosa.

Two days later, as soon as the sky was bright, Zhao Quan got up early. The smell in the tent was so bad that the comrades-in-arms were still sleeping. So, Zhao Quan took a leisurely walk to observe the surrounding scenery. Although I have been on the Qinghai-Tibet Plateau for many days, I am busy with tasks all day long, and I have no leisure to enjoy the scenery. Oh! The winter on the Qinghai-Tibet Plateau is so beautiful, as far as the eye can see, the surrounding mountains are all covered in silver, without the slightest variegation. On the top of the mountain in the east, a small bloody sun is held up, and it is particularly delicate in the snow-colored world. The sun expanded little by little, a little, a small half, a half, a large half, and finally a round and huge fireball struggled out of the embrace of the snow-capped mountains and rose to the top of the snow-capped mountains, and the Qinghai-Tibet Plateau was filled with the brilliance of the sun.

"It's beautiful, it's great!" Zhao Quan couldn't help but sigh.

"What's so pretty? Really great? At this time, Ouyang Qian also came out of her small yurt.

"Yellow sheep!" Ouyang Qian suddenly screamed.

Zhao Feng, Ouyang Yong and others also quickly came out of the yurt when they heard the sound.

They followed the direction of Ouyang Qian's finger, and sure enough, they saw four or five yellow sheep, looking up at something. There are many yellow sheep here, and they can see them every day, more than two or three hundred in groups, and few dozen in groups. Zhao Feng told them that yellow sheep were everywhere on the Qinghai-Tibet Plateau. They are so fast that of all the wild animals, no one can outrun the yellow sheep. However, wolves are the natural enemies of yellow sheep, and a wolf eats thirty or forty yellow sheep a year. Zhao Feng also told them that the yellow sheep had a fatal weakness, that is, a soak of urine at dawn. The first thing they do every morning is to pee. Stay motionless when peeing, and finish peeing no matter what happens. This gave the wolf an opportunity, and the wolf stared at the yellow sheep at night, and patiently lurked near them, and in the early morning when the yellow sheep peed, the wolf rushed up to bite them to death and eat them.

They looked at the yellow sheep again, the body length was about one meter and a half, the height was one meter, the earthy yellow hair, the belly was white, the head was small and exquisite, there were two short horns, the neck was slender, the tail was upturned to the sky, and the tail of the yellow sheep with their back was white, very beautiful. They all looked up at them, as if they weren't very afraid.
