After passing this section, the army continued to march at high speed.

The continuous fatigue march consumed the physical reserves of the soldiers. Sometimes, the marching column needs to be rotated to lead the team, so that the soldiers behind can squint for a while as they walk.

True, the soldiers were physically marching, but their consciousness was half-asleep, dazed, and barely rested. It's not that this army is weak in willpower, but that it has launched extreme physical and mental challenges in order to achieve tactical goals.

It's just that in the next few days, there was bad weather, and the strong wind and cold caused more and more soldiers to fall behind, and the baggage in the rear could not keep up with the pace of progress.

Winter camping is physically demanding. Perhaps, there is not much difference between a one-day camping in an army and living in a house, but if it lasts for five days, there will be many problems with injuries, illness, physical fitness, and execution.

These days, only 4,000 people can still maintain the speed of 80 miles of mountain roads a day, and the 2,000 soldiers and horses behind can only walk 40 or 50 miles. Even when it was only a day's journey from the water in Luyanshui, even the mountain infantry trained by Yu Poison and the unloading of the mountain troops who had been working in the mountains all day could not keep up.

Yu Poison and Shen Long decisively ordered the whole army to rest for half a day and hold a meeting on combat preparations.

The current situation is that Yu Poison and others are located in the south of Fushi County, and they are only separated from the old county seat by a stretch of water. It is expected that the retreating soldiers, horses, troops, and livestock of the Xiongnu will come from the Han Straight Road in the southeast and along the Haoyanshui Road to the northwest.

The original plan was that they could take the city of Fushi first, delay the pace of the retreat of the Xiongnu, and then wait for the follow-up reinforcements to arrive and encircle and annihilate them together.

However, considering the limited freezing of the water in Luyan, it is estimated that it will be necessary to build a pontoon bridge or wade across the river. When the outflanking soldiers and horses passed through the luxurious water, once they encountered the enemy's front and rear attacks, the consequences were unimaginable. So make some adjustments.

Yu Poison led 3,000 soldiers and horses around to a clearing on the Han Straight Road and the Luyan River to intercept the enemy.

Shen Long and Xue Xia gathered the follow-up soldiers and horses here, and on the one hand, set up a temporary camp to accept the stragglers and recover their strength a little. On the other hand, you can build equipment and be fully prepared to go to the city in one go.

Shen Long promised to take the city of Fushi. The group of unloading troops and engineers led by him were not first-class in battle, but no one dared to claim the first in their ability to siege and climb cities, and they claimed to be second.

Therefore, Yu Poison led 3,000 soldiers and horses, carrying only limited supplies and logistical equipment, to occupy and block the enemy's return route before the arrival of 30,000 Huns.

Yu Poison looked at the soldiers around him, they had eaten well and lived warmly for more than a year, but they were not satisfied with pleasure and neglected training.

On the contrary, they take pride in enduring cold and hunger for a specific period of time, pushing their limits. This spirit makes them as proud of their martial virtue and dedication as the dreadnoughts who have left their jobs.

Although they are the Tuntian Army, they are also an important part of the Xinxi Liang Army, and the backbone of them are the elite who have experienced a hundred battles. Not to mention the Huns who plagued their neighborhood, they were the elite of Yuan Shaojun, as long as they fought in the mountains, they were also confident that they could win.

Yu Poison glanced back, and the northwest wind blew so that he couldn't open his eyes.

They are now deployed on the Han Straight Road and on the banks of the Luyan River, and control the small high ground nearby. In the city of Fushi, the water has changed from east to west to north and south. On their east flank was the extravagant water filled with thin ice, and some of the enemy's light infantry could run through it in a scattered manner, but the livestock and armor had to be left behind.

The leader of the scouts ran over and said, "Tell the captain that only a few traces of horses have been found in the vicinity in recent days, and there is no sign of a large army or herd passing by." ”

Yu Poison said: "Very good, it seems that the outflanking has been completed, just wait for Zhang Lu, Zhang Zaiyi and them to encircle and annihilate the enemy army in one fell swoop." The herald ordered all the staff to be on alert, and there would be a fierce battle in a few days. ”

"No!"

On the seventh day of the escape, King Lu and his entourage caught up with the departing tribes at the junction of Zoumashui and Luyanshui. Physically and mentally exhausted, they sent messengers to Fushi and Shuofang to ask for help, and then repaired on the spot for a day.

This place is close to Suide County in northern Shaanxi in later generations. Most of the original Han Chinese have moved to Sanfu, and there are not many people living in it at present. It's just that every year, there are Qiang people and Xiongnu tribes grazing back and forth, and the roads that the herds have stepped out show that this is also a place with abundant water and grass.

After eating a fat but not greasy roasted whole sheep, and sleeping in a warm felt canopy, Yu Lu Wang and others temporarily forgot the horror of the Han soldiers and horses, and slept all day.

There's a reason why they dare to relax. In the past few days, they have fled like flying, and even the horses have run lame more than a hundred, and the rest of the mounts have also eaten up the beans and hay, and then they have run to this place.

Even if the Han army had pursuers, it would not be possible to catch up so quickly. What's more, the five hundred cavalry, one person and two horses, will definitely try their best to pass on the news if they encounter the enemy's situation. But now all signs indicate that the Han army is pursuing slowly, and the main force is still in the Gaonu area, digesting the previous gains.

The Huns were not afraid of this situation, they thought that there were still soldiers and horses of the king of Shuofang in the rear, and there was a main army of 100,000 on the other side of the river. This time, the main force of the Xinxi Liang army was indeed fierce, but it was also a powerful sneak attack, and the frontal decisive battle was not the opponent of their Huns.

On the third day, the weather was still relatively bad.

The king of Lu was reluctant to let his tribe suffer from the cold, and he did not want his livestock to face too much loss. So I continued to rely on the camp and stayed for a day. That is, on the same day, Yu Poison and others were also repairing and making a plan to divide the troops into battle.

On the fourth day, 3,000 Hun soldiers and 50,000 Huns, old and weak, drove 200,000 cattle and sheep on the last part of their lives.

In only half a day, the scouts in front discovered Yu Poison's soldiers and horses. At the same time, the 500 cavalry who remained in the rear also fled, bringing the news that the enemy had suddenly accelerated the pursuit and had pursued within 200 miles.

King Lu couldn't imagine how the Xinxi Liang army descended from the sky, and it stands to reason that the road they took was the fastest road to the north. If the other party crossed the mountains and mountains, how could they go ahead of them within ten days?

And the back almost synchronously began to pursue, this is not a coincidence, is it really a god on the other side?

This is why he underestimated the training and tacit understanding of the Xinxi Liang Army. When Yu Poison successfully crossed the upper canyon of Zoumashui, he sent someone to deliver the news back as soon as possible.

Zhang Lu and Zhang Ji in the direction of Gaonu soon received the wolf smoke signal and immediately launched a pursuit.

The 10,000-strong army has experienced sufficient rest and recuperation, and has taken a smooth road, so it is natural that it can march more than 100 miles in a day. In the face of an army of 10,000 recuperated and recharged, it was impossible for the 500 Hun sentinels to have the effect of delaying, and in the end, of course, they fled.
