"Order, the whole army retreats, go back to the grassland!"

Hedu was so excited that his hands trembled a little.

"Brother Shalin, our chance has come!"

Sha Linmu's eyes lit up, and he smiled sinisterly: "Hehe, the Qin people gave us such a big gift, I want to go and thank their emperor in person." ”

"Hahahaha......"

When they lead 70,000 cavalry back, no matter whether the Qin army arrives at the Wolf Court or not, Toumanshan Yu will also die at the hands of the Qin army. When the time comes, Heda is nowhere to be found, and Mu Erti is still stupidly attacking Qin Chang, and he is the only one who is in the position!

When the Wuwei Qin army wondered why the Huns retreated immediately as soon as they arrived in the city, the Qin army at the eastern foot of Helan Mountain did not wait for Heduye, but waited for an unexpected person.

"Report! General, there are 50,000 Hun cavalry coming towards Helan Mountain! ”

Ding Chuan was taken aback: "We just arrived here, and they returned to the division?" Could it be that the news of the suspicious soldiers passed so quickly? ”

"General, the Hun cavalry came from the north, not from the direction of the Hexi Corridor."

After listening to the scout's words, Ding Chuan looked at the captains in the tent in a daze, what the hell is going on?

It is the disappeared Heda who came to Helan Mountain!

He Da originally waited at the western foot of Yinshan Mountain according to the order of Touman Danyu to pick the fruits of the victory of Hedu Ye and Muerti, but by coincidence, the Tancai captured a Rong tribesman who escaped from the land of Xinqin.

Under interrogation, the Rong people told Heda that since the completion of the Great Wall, there are almost no Qin people in the new Qin land, all of them are Xiongnu and Qiang people who have surrendered to the past, and a small number of Rong people are bent on returning to the Xiongnu.

Heda listened, this is a good thing! They have coveted the Hetao area for a long time, and now they are empty in Yinshan, and the war in Wuwei cannot end without ten days and half a month, why don't they take advantage of Hedu to contain the Qin army and capture the Hetao in one fell swoop? This can not only increase the strength of the Wolf Court headquarters, but also add points to the position of Shan Yu in the future, the best of both worlds!

He immediately made a decision in his heart, and hurriedly ordered the army to be assembled and came towards the Hetao area.

As everyone knows, this Rong people escaped from the New Qin Land because they committed a crime, and in order to spare Heda's life, he made up the story of the Hetao area dedicated to the Xiongnu......

Heda marched all the way to the southeast, and really met little resistance, until he reached the west bank of Deshui. It was originally a place where Great Qin and the Xiongnu competed, and naturally there were no Qin people.

Without a boat, Heda could only look at the water and sigh. Calculating the time, Hedu and they should have already begun to attack Wuwei, and if they go south along the west bank of Deshui, they can directly reach behind Hedu, so that they can realize Touman Danyu's plan as soon as possible.

Without hesitation, he ordered the army to move south along the German River.

Walking to the eastern foot of Helan Mountain, Heda couldn't help but laugh happily.

"There are high mountains in the west and Deshui in the east, which is suitable for farming. If you take this valley of more than 300 miles, you can also add a granary for us. ”

But I don't want to, there are 100,000 Qin troops waiting here.

Ding Chuan could already faintly hear the sound of the Hun cavalry roaring and neighing on the mountain, and muttered: "100,000 infantry against 50,000 cavalry, I'm afraid it's a bad battle!" ”

The river beach is 60 miles from east to west and 300 miles from north to south, and there is no danger to defend. Even if the Qin army was accustomed to battle, it was difficult to withstand the onslaught of 50,000 cavalry.

Suddenly, a scout came to report: Meng Tian will order!

Ding Chuan hurriedly took it, and frowned slightly after reading it.

It turned out that Heda did not hide his whereabouts all the way, and the scouts had already discovered the whereabouts of the Hun cavalry. Meng Tian expected that he would not be able to cross the river, so he would definitely choose to go south along the river, passing through the eastern foothills of Helan Mountain, so he immediately made arrangements.

"General Chuanben will order that the 30,000 Chinese troops be merged into the front army, and on both sides of the marshland in the middle of the river beach, two phalanxes will be formed, with shield soldiers in the front, Ge soldiers in the rear, and crossbow soldiers second. Order the 40,000 men of the rear army and the people who transported grain and grass to line up in the south of the swamp in turn, and set up more flags to be suspicious soldiers! ”

"Yuan Nong, the former commander of the army, led 5,000 people, with all the remaining bows and crossbows, and quietly went to the rocky ditch along the foot of the mountain to hide, so as not to reveal his whereabouts!"

The army immediately took action, and half an hour later, when the Qin army finished fighting, He Da also happened to come here.

Looking at the Qin army waiting in front of him, He Da was shocked, this is already the periphery of the Great Wall, how can there be so many Qin troops! As far as the eye can see, there are 30,000 people on each side of the swamp, and behind them countless flags are displayed, as if there is no end in sight.

The pro-army stepped forward immediately: "Prince Heda, Shan Yu explained that our mission is to assist the four major tribes to attack Wuwei and Qinchang, and the Qin army has such a large number of people, if we can't defeat them for a while and a half, I'm afraid it will ......."

He Da frowned slightly, pondering for a long time: "Is the road we came over safe?" ”

"There are cavalry left behind every ten miles, absolutely safe!"

"Okay, turn around and go back! The border army of the Qin people is only two or three hundred thousand, and it seems that there are nearly 200,000 people here, and they should be going to reinforce Wuwei. We bypassed, they couldn't catch up with our speed, as long as we took Wuwei and Qin Chang, no matter how many infantry he had, he wouldn't be able to defeat us on the grassland! ”

With that, he turned around and headed north.

And at the only intersection in and out of the Helan Mountain River Valley, close to Deshui, 30,000 people, including the Qin army and the Qin people in the border areas, are frantically digging the Deshui embankment!

Whether it was occupied by the Qiang, the Xiongnu, or the Great Qin, they all attached great importance to this rich river valley. Deshui enters the Loess Plateau from here, and the water level in the upper reaches is almost the same as the ground, so the river embankment has been continuously strengthened in the past hundred years, resulting in the increasing water level of Deshui.

Heda's cavalry remained in the middle of the densely populated river valley, unaware of the movements of the Qin army.

When Heda led the cavalry and could see the pass of Wuhu Mountain in the distance, he suddenly heard a rumbling sound in the distance.

"What sound?"

"It's the sound of the river, right? But how does it seem to be getting closer? ”

Before Heda could react, Deshui in the distance was already like a tiger descending from the mountain, and the waves swept towards them.

Heda's eyes were cracked, and he roared angrily: "Attack the north with all your strength, quickly!" ”

Then he picked up the whip and beat the horses under him with all his might, and hurried towards the pass of Wuhu Mountain.

But the cavalry behind is not so lucky, no matter how fast the cavalry is, are you still so fast and ruthless? With an army of 50,000, it will take time to raise the speed!

He Da couldn't manage so much, he just rushed forward with his own life, and the flood behind him was monstrous, and it swept away the cavalry in the rear in an instant. The river beach was already wet and watery, and when the water soaked in the water, it immediately became a swamp, and the water that submerged the depth of the horse's calf made the cavalry trapped here, unable to move.
