I am the system

Time flies for three days.

Guessing that Cao Cao had almost sent troops, Lu Bu finally ordered to send troops, targeting the Xiongnu. (The distance is too far to get real-time news, so we can only estimate according to the agreed plan.)

Although the Huns are the most brave and skilled fighters among the Xianbei, Huns, and Qianghu tribes, they are also the smallest in population, territory, and power among the three tribes, and they also have the least military strength.More importantly, the territory of the Xiongnu was sandwiched between the Xianbei and the Qianghu. Destroying the Huns would mean breaking the union of the three tribes, leaving them to fight on their own.

Following Lu Bu's order, the gate of Yanmenguan City was opened wide, and the soldiers marched out of the city in a neat line.

The [-] troops walked out of the closed gate of Yanmen Pass like a long dragon, and the order of the team was as neat as dragon scales.Among the army, there are also a large number of cattle and horses dragging artillery and a large amount of supplies, as well as the army's food and grass.And in the middle of the team, five tanks made rumbling roars, as terrifying as giant war beasts, making people daunting.

In the distance, behind a certain grassy slope, a few Huns and Xianbei cavalry looked at Lu Bu's army leaving the city, especially at the tanks that were driving out of the city.

~~~

"Report!"

One day later, eighty miles away from Yanmen Pass, in the camp of the Huns, spies came hurriedly on horseback, shouting.

"General, the gate of Yanmen Pass is wide open. Lu Bu personally led the army to storm out, followed by a huge iron beast. It is estimated that we will arrive here in one day."

The spies came to the camp on horseback and saw that Hu Tushu was just at the gate of the camp, so they rushed to report.

"It's still here!"

Hearing this, Hutushu's expression turned ugly.

Three days ago, when he saw the sky over Yanmen Pass shrouded in red light, he knew that Lu Bu was going to send troops against them, so they immediately withdrew with their subordinates and separated from the troops of the other two clans.

I thought they withdrew, and the coalition forces of the three races also separated.For Lu Bu, their threat was much smaller. Lu Bu would not take the risk of chasing them into the prairie, and it was not worth the risk, but he did not expect that Lu Bu would still send troops, and the target was still the Huns.

"General, what should I do?"

The leader of a tribe asked Hutushu, his eyes filled with worry.

He didn't want to try the power of the fairy weapon in Lu Bu's hands anymore.

"This!~" Hearing this, Hu Tushu couldn't give an answer for a long time.

He didn't have the courage to fight Lu Bu's army, and I'm afraid his warriors didn't have the courage either.But if there is no fight, I am afraid that Lu Bu's army will go deep into the grassland as if no one is in the land.

Although the grassland is their home field, but Lu Bu has a fairy weapon, relying on the fairy weapon, I am afraid that Lu Bu will still have the upper hand.

As for the peace talks, he would like to, but would his great Chanyu be willing?Hu Tushu didn't know, but he definitely wouldn't be willing now, otherwise he wouldn't have sent tens of thousands of reinforcements.

"Let's retreat first! Tell the warriors to prepare for battle!"

After some thought, Hu Tushu gave the order.

Withdrawing first is the only decision he can make now.At least, let Lu Bu's army really go deep into the grassland, so that even if there is a war, they can have more confidence, not now.

Of course, it is essential to send spies to continue to monitor the movements of Lu Bu's army.

--------

At the same time, the chief generals of Xianbei and Qianghu also learned about the dispatch of troops from Yanmen Pass.

However, compared to the ugly face of Hu Tushu, the leader of the Xiongnu, they didn't have so many thoughts. Now that the coalition forces of the three clans have separated and acted on their own, they are happy to see Lu Bu lead the army to attack the Huns. They can't kill Lu Bu. They don't want to be an enemy of Lu Bu anymore, but they are happy to see the decline of the Huns, and they may even annex the Huns.

--------

On the other side, Hu Tushu has ordered the entire army to withdraw from the camp, intending to speed up the withdrawal.

Although Lu Bu was still seventy miles away from them, and it would take at least a day to get here, he was not sure whether Lu Bu, who had the help of a real immortal, would appear in front of him sooner or later.

Although he doesn't know the methods of the immortals very well, he also knows that the methods of the immortal family are unpredictable, and there may be a way for an army to travel thousands of miles a day.

--------

Hu Tushu didn't know, but his guess was correct. After Lu Bu's army was blessed by Wang Yuan, their marching speed has been greatly improved. There is still no major problem for two hundred miles, but it is not slower than their marching speed at all.

Now Lu Bu has determined the direction of their retreat based on their retreat traces, and even led the army to detour from the side, preparing to ambush them in front of them.

As for whether Lu Bu would go the wrong way, Lu Bu had the tablet map given by Wang Yuan in his hand, and with the navigation ability, he would never go the wrong way.

————Three days later————

Lu Bu has led his army to detour to Langya Valley.

This is a rare valley terrain on the grassland. There are layers of mountains on both sides, and in the middle is a huge valley with a width of 300 meters to 800 meters and a length of more than 20 miles. Because of the lush forests in the valley, a large number of wolves are hidden. The group is named Langya Valley.

In the mountain forest, there is a grass road with a width of [-] meters, which can be marched across.

At the same time, this is also a way for the Huns to retreat. Although it is not the only way, it is the shortest way.There are mountains on both sides of Langya Valley, only this valley can pass through the mountains.

If you don't pass through the middle of Langya Valley, or you have to climb over the mountains on both sides, but the mountains are more than [-] meters high, the slope is very steep, and one is connected to the other, how can it be so easy to climb.

Or just take a detour of more than 130 miles.

"Zhou Tong, are the cannons ready?"

In the forest of Langya Valley, Lu Bu asked a general.

"My lord, everything is ready. As long as the Xiongnu enter the range of ten miles, they can fire at any time, so that they can taste the power of the fairy weapon again!"

The general who was questioned answered immediately.

The howitzers were too bulky, and they didn't bring them, but they brought all thirty mountain cannons.

"Zheng Wang, are the machine guns set up?"

Hearing this, Lu Bu nodded and asked another general.

"My lord, the key positions have been arranged. As long as those Xiongnu enter the Wolf Fang Valley, none of them will be able to get out."

Zheng Wang, who was in charge of commanding the machine guns, said immediately, his tone full of confidence.Under the blockade of fifty Maxim machine guns, not to mention that mosquitoes cannot fly out, but he is also confident that he will not let a Hun soldier go.

"Everything is ready, only the Huns are sent into the urn!"

Lu Bu said with a smile.The spies have come to report that the Xiongnu soldiers will arrive at Langya Valley in half a day.
