Tuobali was slightly stunned.

He looked stunned, he didn't react for a while, and he couldn't figure out why.

Sima Yi, wasn't he still encouraging him not to give up hope and fight Su Zhe to the end ten days ago?

At that time, Sima Yi was so confident, as if he could help him turn things around and recapture Monan one day.

Tuoba Liwei really believed it.

But now, someone told him that Sima Yi didn't flee to Mobei with him, but fled to the east?

Where is it to the east, Goguryeo?

Could it be that Sima Yi's wife, with one thing on his lips and one thing behind his back, turned his back on him?

"I don't believe it, I treat Sima Zhongda so thickly, it is impossible for him to turn his back on me, it is impossible~~"

Tuoba Li shook his head vigorously, unwilling to believe this cruel truth.

Soon, people kept coming and told him in person that Sima Yi had indeed fled east with his family and had not crossed the desert with the large army.

Little by little, Tuobali's hope faded away, and was gradually replaced by anger.

"Khan, this is a letter left by Sima Yi to the Khan, claiming that there is a clever plan to break the enemy, and tell the little one to wait for us to get out of the desert before giving it to the Khan."

A ragged Xianbei nobleman presented a letter and a bag to Tuoba Liwei.

Tuobali opened it with a slight tremble, and couldn't help but be furious, so angry that his face was red.

In his letter, Sima Yi put all the responsibility for Xianbei's failure to such a point on Tuoba Liwei's body, saying that he Tuoba Liwei had the ambition of the male lord, but he did not have the ability of the male lord to humbly accept advice, and the defeat to such a point could only be self-inflicted.

Therefore, in order to oppose Wei's plan, Sima Yi decided to give up on him and moved his family to Goguryeo, hoping to use Goguryeo's hand to defeat Su Zhe and save the people of Li in the world.

In the end, Sima Yi also claimed that in order to repay Tuoba Liwei's kindness to him, Sima Yi finally offered him a plan to ensure that he could avoid being lost to Su Zhe.

Sima Yi's strategy was to suggest that Tuoba Liwei take his Xianbei remnants and follow the example of the Northern Xiongnu in those years, migrate to the west and flee, and escape from the Mobei Plateau as far as possible.

"Sima Yi, you ungrateful villain, vain Khan treats you so seriously, you actually treat me like this, villain, villain~~"

Annoyed and angry, Tuoba Li Weiwei, roared and scolded, and tore the letter in his hand to shreds in anger.

The angry scolding continued, Tuoba Li scolded Sima Yi slightly, scolded for a quarter of an hour, and scolded until he was exhausted, and then stopped.

"Khan, what are we doing now, now?" The Xianbei aristocratic general beside him asked cautiously.

Tuobali slightly untied the wine bag, raised his head and poured it wildly, and poured the whole bag of mare's milk wine clean.

Under the influence of the smell of wine, Tuoba Li strengthened his courage slightly, and said proudly: "Without the assistance of Sima Yi's dog thief, Ben Khan can still make a comeback, and the whole army will continue to move forward and go to Dragon City!" ”

Tuoba Li turned on his horse slightly, rode his horse down the dunes, and continued to walk towards the grassland.

Thousands of Xianbei soldiers and civilians could only shake their heads and sigh, dragging their tired and lonely bodies towards the vast grassland.

……

In Eagle City, a grand celebration banquet is underway, and the participants are 200,000 Wei soldiers.

This joyful victory, killing 1560,000 Xianbei soldiers and civilians, and capturing a total of nearly 1 million cattle and sheep, can be called the most lucrative victory since Su Zhe led the army.

Millions of cattle and sheep, if converted into grain, are enough for Su Zhe's 200,000 troops to eat for more than half a year.

This also means that Su Zhe's expedition to the Northern Expedition this time is almost equivalent to not consuming a grain of grain from the Great Wei, all of which are from the Xianbei people, and they all rely on war to feed the war.

With such a rich harvest, Su Zheyan can not celebrate a day.

On that day, the entire Eagle City, inside and outside, turned into a sea of joy.

Su Zhe slaughtered nearly 20,000 sheep in one go and distributed them to the soldiers, so that they could eat enough.

The soldiers who survived the bloody battle were rewarded by the Son of Heaven, and they were naturally overjoyed and grateful.

They drank to their heart's content, ate meat to their heart's content, vented the joy of victory, and sang and danced to their heart's content.

After three consecutive days of celebration, the soldiers' mental and physical strength were greatly restored, and their fighting spirit was once again wild.

Su Zhe left the infantry army to clean up the battlefield, and with an order, he led 100,000 iron horsemen to the north to the Yin Mountain Pass, crossed the Yin Mountain, and continued to advance to the hinterland of the Mobei grassland.

Of course, Su Zhe's ambition cannot stop at recovering the Monan grassland, let alone satisfy him because of a million sheep.

He wanted to go to the Mobei grassland in one go, take Longcheng directly, annihilate the remnants of the Xianbei people in one fell swoop, and completely solve the threat of the northern frontier of the Great Wei.

Although the Yinshan Mountain Range is not as difficult to walk as the desert, it is also a mountain range, and the mountain road is far less easy to walk than the plains.

Further on, there is the endless steppe, which is wider than the desert steppe, and can reach the Beihai (now Lake Baikal) where Su Wu herded sheep.

According to Zhang Liao's guide, Su Zhe led 100,000 iron horsemen and went straight to Dragon City.

Although the Mobei grassland is vast, and the Xianbei people seem to live in the grass, it is difficult to find them, but in fact, it is not difficult to catch them.

The reason is simple, it's winter.

As soon as the cold winter begins, the Mobei grassland is snowy, and the temperature drops sharply, which is more terrible than the winter in the Central Plains.

In the meantime, the cold snap from Siberia will ruthlessly sweep the entire Mobei steppe, and the blizzard will swallow everything.

Therefore, every winter, the Xianbei people of various departments will leave their grasslands and gather in one of the few places on the grassland, which have the terrain that can withstand snowstorms, to report to the group for warmth.

Dragon City is the largest sheltered city of the Xianbei people.

Previously, Zhang Liao had figured out the location of the place on the Mobei grassland, where the Xianbei people used to avoid the blizzard.

Therefore, what Su Zhe had to do was to lead the army to sweep these sheltered places, and naturally he would be able to find the main force of the Xianbei people.

Su Zhe and his iron cavalry were not afraid, he only needed to withdraw from the Mobei grassland in time before the snowstorm came.

The Xianbei people had no choice, they had to rush to Longcheng from all over Mobei a month in advance, if they wanted to avoid the attack of the Wei army, and deliberately delayed the time, they might not be able to rush to the time before the blizzard came.

Su Zhe grasped the weakness of Tuoba Liwei, and expected that he had no choice but to gather his hundreds of thousands of soldiers and civilians, as well as the remaining cattle and sheep, all to Longcheng, hoping to defend Longcheng to the death, and drag it until the Wei army had to retreat in order to avoid the blizzard.

An army of 100,000 marched northward, crossed thousands of grasslands, and finally arrived in Dragon City before the first snow came.
