The wind rolls the red flag and does not turn over, and walks with the wind all over the rocks.

12,000 Qin troops plus 30,000 Tuyuhun troops braved the wind and snow to walk on the plateau. The wind is bitterly cold, and the further south you go, the worse the climate becomes.

At this time, Tuyuhun's soldiers and horses were fine, but the Qin army of the heir industry was gradually unbearable.

They have begun to feel the malice brought by the plateau, and most of the soldiers and horses of the heirs come from the Guanlong Heshuo area, where they are all in the Loess Plateau, but from the south of the Qinghai Lake, the terrain is constantly rising, and they climb the Qinghai-Tibet Plateau.

The height is getting higher and higher, and the altitude sickness is getting more and more severe.

The altitude of the Hehuang Valley is only more than 2,000 meters, while the altitude near the Dafei River rises to more than 4,000 meters.

Many Qin soldiers began to experience dizziness, headaches, palpitations, and even diarrhea.

Even if the reaction is mild, I feel tired, feel weak in my limbs, and pant heavily.

Because Heiye was about to be caught off guard by the Heavenly Pillar King, the 42,000 people he led this time were advancing lightly.

From the low-altitude Qinghai Lake, they quickly entered the high-altitude Dafeichuan, and the soldiers did not have a process of adaptation, and the reaction was even more violent.

Even if you are riding a horse, you feel as if you are marching on foot with a load.

"Under the festival, this place is very evil, our brothers can't stand it, do you want to take a rest?"

Si Ye carried a Mo knife in his hand, rode on his horse and turned back, watching the red flags rolling across the mountain roads and the long procession winding along. He shook his head, "No, Cheng Mingzhen and Xue Wanjun's two groups of men and horses are already on their way, if we can't arrive at the scheduled time, they may be surrounded and annihilated by the Tuyuhun people." ”

"Brothers, grit their teeth and persevere, when we get to Dafeichuan, we will destroy the five thousand soldiers of the Tianzhu King, and then we can rest."

The soldiers who reacted violently were left behind by the heirs, and they were allowed to rest and recuperate in the back, and then they came.

Then move on.

From Qinghai Lake to Dafeichuan, although there is a valley road feasible, but the twists and turns, the road is difficult to travel, it seems to be only two or three hundred miles, but in fact there are seven or eight hundred miles.

Along the Hot Spring Mountain Road, the further south they went, the more adverse reactions occurred in the Qin army.

When there were still more than a hundred miles away from Dafeichuan, the Qin army began to die.

In fact, these people died of altitude sickness, acute edema or heart disease, but the current military doctors can only be classified as bad weather.

At this time, the sky is full of snow, fluttering and sprinkling.

There are still more than 100 miles away from Dafeichuan, but the Qin army has 12,000 people, and at this time it has already reduced its strength by no less than 2,000.

The remaining 10,000 people were also exhausted, as if they had just experienced a battle for three days and three nights.

Faced with this situation, the generals once again asked the heir whether to rest first.

"Pick out the soldiers from the army who are still in good health and have good physical strength, and continue to move forward with the commander."

Of the 10,000 people, only 3,000 were singled out.

The remaining seven thousand had to stay and recuperate for the time being, and wait for the soldiers who had fallen behind.

After feeding the horses and eating simple porridge with meat floss, Siye led 3,000 Qin troops and more than 20,000 Tuyuhun cavalry to continue to advance in the vast snow.

After five days of continuous marching, Siye finally arrived at Dafeichuan.

Dafei Sichuan is surrounded by mountains to the west and the Yellow River to the east.

Dafei Lingshang.

The Tianzhu tribesmen's army stood on the ridge, stationed 5,000 soldiers, and stockpiled a lot of grain, grass, equipment and other baggage.

In the wind and snow, Tianzhu Ling, the son of the king of Tianzhu who guarded the camp gate of Dafeiling, got a piece of information that made him uneasy, his rangers, found that a group of soldiers and horses appeared on the east bank of the Yellow River, about 10,000 people, looking at the flag is waving the red flag, among which there are many Longyou tribe Qiang horses.

This news alerted Tianzhu Ling, who was the eldest son of the Tianzhu King and a battle-hardened general.

Previously, the king of Tianzhu sent envoys to the Qiangdi tribes of Longyou and Hexi to persuade them to send troops. But now it is the Red Flag that is coming, which is obviously the Qin army.

He immediately sent a light horse to report to the King of the Heavenly Pillars.

But in the next few days, bad news followed.

To the southeast of them, another army of horses and horses came.

"The troops and horses in the northeast should have come over Lianyun Mountain, and they probably came from Xiping County or Shuihe County. The southeast branch is most likely from Lintao County and came over the west-leaning mountains. Unexpectedly, the Qin army came so quickly, and actually came over the mountains, let alone that there would be so many Qiang troops. ”

The Qin army on the opposite side of Xiqian Mountain and Lianyun Mountain came, so with his keen experience in warfare, he immediately realized that these two roads could never act alone, and they must be united.

And since there were two armies to the east, where it was most difficult to march, there should be a large army from the north.

After some speculation, Tianzhu Mausoleum came to the conclusion that this time it was at least a siege on three sides, with at least 50,000 soldiers and horses.

"General, shall we continue to hold out and wait for help, or shall we get out of here?"

Tianzhu Ling said, "Now it is obvious that the Qin army is coming for these five thousand people on our Dafei Ridge, and they want to eat us in one bite. ”

The camp fence on the Dafei Ridge is not a stone city fortress, just a wooden fence, but it also has a certain fortification, occupies a dangerous position, and the defense capability is acceptable.

But 5,000 against 50,000, especially in the face of the Qin army, the Tianzhu Mausoleum is not sure.

Stick to the wait for help, but I'm afraid that I won't wait for the reinforcements to arrive.

"General, why don't we move to Wuhai, the king is gathering in Wuhai."

Wuhai City is the base camp of the Tianzhu King, in the southwest of Dafeiling, close to Wuhai Lake.

The original plan was to divide the troops into two routes to the north, and the king of Tianzhu gathered the soldiers and horses of the three tribes of Tianzhu in Wuhai, and Tianzhu Ling led 5,000 people to camp on the Dafei Ridge in the east, and stored grain and grass there, waiting for 10,000 horsemen from Tubo to come.

Then when the time comes, the east and west will divide the troops and go north.

But now, the Tubo people have not yet arrived, but the Qin army has killed them first.

"If you leave now, it will be difficult to carry the baggage, but if you give up these baggage, the Tubo people will have no supply of food and grass when they come."

"Then take the baggage with you, we'll still have time."

Tianzhuling is a Tuyuhun person, but also a Qiang person, he learned the art of using soldiers since childhood, that is, he will never hit hard, he will fight if he fights, and he will leave if he can't fight, and then fight when he turns back to find an opportunity.

Therefore, at this time, if a Qin army guards Dafeiling, what may come to mind is to hold on.

However, Tianzhu Mausoleum decided to withdraw from the encirclement.

Grab the bull by the horns.

Tianzhuling ordered the whole army to evacuate Dafeiling, and at the same time take the baggage away.

Five thousand warriors, plus about 10,000 tribesmen, followed by a heavy load, and the line was extremely long. The yaks were loaded with heavy loads and traveled very slowly, which greatly slowed down the retreat of the Tianzhu Tomb.

The sky was overcast and the snow was vast.

The Tianzhu army evacuated Dafeiling and walked east for a day, but it only took dozens of miles to walk, and seeing that the sky was about to dark, there was a line of black tide on the vast snowfield in the north!

Immediately after, a red flag jumped out, dazzling!
