Yelu Abaoji's will to fight is very resolute, he wants to show his courage and fighting spirit, and prove that he has at least something no worse than Li Ye.

However, before the Tang army in Beikou broke through the Khitan camp, the Khitan army received an order to retreat, requiring the soldiers who could leave the battle to abandon all their baggage and leave the battlefield at any cost, and quickly return to the Khitan Yikun Prefecture.

The Si Jinbu did not go to the battlefield to fight to the death against the Tang army, but was the first to return to Yikun Prefecture in Qilaotu Mountain, relying on the geographical advantages to build a defensive line and respond to the retreating Khitan troops.

Not only the Khitan army in Beikou, but also the Khitan battalion outside Pingzhou and Yuguan also received such an order. The slight difference is that the battle situation at Yuguan has not yet entered a situation of imminent collapse, so the main general will be required to leave the broken rear part to cover the retreat of the main force.

Such an order was naturally issued by Yelu Abaoji, and only he could issue it.

This shows that Yelu Abaoji was so angry in the face of the heavy blow that he trampled the great sacrifice of the Divine Sect into pulp, but he did not lose his mind at the last moment.

"In a decisive battle with the Tang Army, the Khitan has no chance of winning. The Tang people said that they should stay in the green mountains without worrying about running out of firewood. The retreat of the army at this time, although it will also suffer heavy losses, but as long as we can preserve a vitality for the Khitan, we have the possibility of a comeback. Burying all the Khitan warriors on the border of the Tang Dynasty is not what I want. ”

When the division was evacuated from the camp, Yelu Abaoji immediately looked at the north entrance at sunset, and said such a thing to the Yelu enemy Lugu beside him.

At that moment, his expression was gloomy and painful, as if he had aged twenty years in an instant.

Yelu Rugu did not answer, and his heavy mood made it difficult for him to speak.

The lonely shadows of the two people and two horses, on the empty grassland, were stretched by the slanting sun.

In this world-wide war against Tang, the Khitan dispatched more than 2 million soldiers, and it is expected that no more than 30% will be able to safely withdraw to Yikun Prefecture. After this battle, the Khitan State has in fact and can only survive for a long time.

The premise is that the Tang army does not chase into the grassland, or Yikun Prefecture can block the Tang army's front.

Before the dawn of dawn fell from the sky, the blood-stained cow egg and the two dogs raised their heads panting like cows, and there was no Khitan in front of them. The comrades beside him were stunned for a moment, and then burst into a tsunami-like shout.

Behind them, there was a mountain of Khitan corpses and a sea of blood, completely covering the lush meadows.

The Khitan army fled overnight, originally wanting to take advantage of the cover of the night and try to open a safe distance, but the Tang army's offensive was reluctant to work day and night, which made their plan impossible to succeed and could only be chased and killed all the way.

Now that the night is over, the corpses lying on the grass have not seen a new dawn. Only the soldiers of the Tang Army, who cheered in the corpses all over the ground, could usher in their glory when they were tired after a night of fierce fighting.

The Battle of Beikou came to an end, in the form of a great victory.

Even if there is still fighting in the future, it will no longer happen in the North Exit. As the border army of Beikou, Niu Dan and Ergouzi, including the Confucian scholars of Yangzhou who came to support and fought bloody battles to be reborn, all got what they wanted at this moment.

Something called a new birth.

In the sky above the battlefield, Li Ye and Li Maozhen overlooked all sides, looked at each other, and were smiling.

The end of the Beikou War marked the end of the national war launched by the Khitan against the northern border of the Tang Dynasty with the strength of the country, and ended in a crushing defeat.

Although there is still fighting outside Yuguan, it will not last for a few days.

"The battle in the north, although it took a long time, was final

It ended in a big victory, and I didn't fail to live up to my duty. Li Maozhen patted her chest and breathed a long sigh of relief, her words full of joy.

Li Ye was noncommittal: "If the Khitan is defeated, will the war in the north end?"

Of course not.

Li Maozhen is well aware of this.

She said solemnly: "If the Khitan does not perish, this war will not end!"

Li Ye looked in the direction of Yikunzhou and played with taste: "Yelu Abaoji thinks that by evacuating from the Great Wall, he will be able to survive and renew his life for the Khitan Kingdom? ”

Li Maozhen pondered: "The remnants of the fleeing Khitan army are retreating in the direction of Yikun Prefecture, and the situation on the other side of Yuguan should be the same. After this fierce battle, the soldiers were very tired, and they wanted to attack Yikun Prefecture, which had geographical advantages, but they were afraid that they would have to cultivate for a period of time. But during this time, the Khitan will definitely strengthen the defense line of Yikunzhou, and the longer the time, the stronger the defense line will be. ”

If the Tang army wants to have a good state and enter the grassland to completely destroy the Khitan Kingdom, it must take a serious rest for a while.

This is a paradox.

Unsolvable contradictions.

But in Li Ye's case, this is obviously not a problem.

He smiled a little proudly: "Si Jinbu did not join the battlefield, but chose to go back to Yikun Prefecture directly to set up defenses, staring at their Tiger Guard Army and Wolf Tooth Army, naturally they will not be idle, and now they have rushed to Yikun Prefecture." Yelu Abaoji thought that if he held Yikun Prefecture, the Khitan would have a way to live, but in my opinion, Yikun Prefecture was the end of his life. I have already dug a grave for him in Yikun Prefecture, and I am waiting for him to go in and sleep. ”

King Qi, who had been working hard for the defense and counteroffensive of the northern border, could not help but feel surprised when he heard this.

She stared at Li Ye with wide eyes: "You already have an arrangement?"

Li Ye gave her a strange look: "Do you think that I will let Yelu Abaoji, who provoked the world's attack on the Tang Dynasty, return to the West Building alive? Will you be satisfied that this battle is only to defeat the Khitan barbarians who attacked the northern border of my Tang Dynasty and offended the majesty of my Celestial Empire?"

Li Maozhen was speechless.

She blushed and said angrily: "Don't think I don't know what you do! When you dealt with Ma Yin, you said that you had secretly contacted the Yellow Head and Tartar tribes on the steppe. So far, I haven't seen them appear, and even when the war was at its most stalemate, you didn't let them do it, aren't you just waiting for today?"

After saying these words in one breath, Li Maozhen was stunned first.

Then she leaned at Li Ye, complacent, and felt very satisfied with her own wisdom of penetrating the other party's plan at a glance.

Li Ye is used to Li Maozhen's occasional childishness, and he is really happy to see the other party, so he doesn't say anything to hit the other party's self-confidence.

He did secretly contact the two tribes of Huangtou and Tatar, who were suppressed by the Khitan and were unwilling to lose their status. These two are big clans on the grassland, and now although they don't have much military strength on the surface, they have a lot of influence, and it is not difficult to gather the old ones.

It's just that Li Ye can't do it to them.

Contacting them before only confirmed the possibility of an alliance between the two sides.

It will take time for the Yellow Head and Tatar Ministries to really raise troops. Let them see the certainty of victory, instead of taking a risky blow, the result of the rebellion failed, but was completely wiped out by Yelu Abaoji.

When the Tang Army and the Khitan Army were in a stalemate, the Yellow Head and Tatar Divisions naturally would not act, and it was too risky to do so at that time. But after the Battle of Yanzhou, he

They saw hope, made up their minds, and began to prepare.

If they hadn't prepared at that time, Li Ye would have been unhappy. When everything was clear and there was no suspense about the outcome at all, what else did Li Ye want them to do? If they wanted to pick peaches, they had to water the trees first.

Now that the Battle of Beikou is over, the Yellow Head and Tatar Divisions have already launched operations.

"It is not easy for the border army to defend the frontier after years of fierce battles, and they can rest. But the Chang'an forbidden army, now is a critical opportunity for them to play a role and contribute to the country, Rao is a little tired, and he must persist until the last moment. ”

When Li Ye said this, he became more and more confident, "Don't forget, we still have the grassland tribal army to drive." Whether it is the tribal army from Fuzhou or the tribal army captured in Beikou, they can fight a smooth battle.

"The Khitan army that retreated to Yikun Prefecture also had a lot of tribal soldiers, and when they saw that the soldiers who were also not Khitans chose to fight side by side with the Tang army, they naturally knew what to do in order to survive. ”

According to Li Ye and Li Maozhen's arrangement, half a month later, the Tang army arrived in Yikun Prefecture in a mighty manner.

In the Tang Army, the Chang'an Forbidden Army is naturally the absolute main force, but this time it is not the Tang Border Army that assists them, but the more than 200,000 grassland tribal army.

The situation of the mountains and rivers of Qilaotu Mountain is more complicated, it is a relatively rare terrain on the grassland, the ravines are vertical and horizontal and there is no lack of flat land, and the Khitan side relies on the terrain to build a number of guancheng, with a variety of deep grasslands of different sizes, which has the effect of dividing the forces of the attacker.

In such a zone, there are many opportunities for war.

This was a battlefield that was naturally favorable to the defenders.

However, the Khitan warriors who had just experienced a fiasco, witnessed a large number of relatives and friends being unable to die in battle, and were only lucky enough to escape with their lives, even if they occupied Guancheng, they did not feel much security, and their morale was not high.

Especially when they saw those grassland tribal armies, shouting and shouting outside the city, showing off their might, many people turned gloomy.

The spirit and high morale of the grassland tribal army at this moment look even better than the Chang'an Forbidden Army.

When they were gearing up, their faces were fierce, and they looked at the Khitan warriors' eyes with extremely hot eyes, as if the other party was not a warrior with extraordinary combat power, but a beautiful slave of cattle and sheep wealth.

To be honest, in the face of the enormous wealth at your fingertips, a well-disciplined army is not as combative as a robber.

The steppe tribal army that came to rob was not fundamentally different from the robbers.

If you insist on saying that there is, it is that their combat power is stronger.

The war lasted from spring to autumn, and the warriors of the steppe tribe had no time to raise fattening cattle and sheep. If they don't rob the cattle and sheep of the Khitans, it will be difficult for them to survive, and their own tribe will also suffer in the cold winter.

Of course, the Khitans who were robbed of their cattle and sheep will definitely not survive the cold winter.

But no one cares about that, because they can't even survive this war.

When there are only so many things to survive – or even fewer than in previous years, the only way to survive is to reduce the number of people who need to eat.

Li Ye looked at the various large and small cities, and said to Li Maozhen with a smile: "The grassland people always covet the wealth of the Han people, and they want to go south to loot at every turn, and now, we will rob the Khitans once." ”

Li Maozhen clenched his fists and said with burning eyes: "I have no interest in the cattle and sheep of the Khitans, but I want to rob them of their qualifications to survive in this world!"

The Battle of Yikun Prefecture officially broke out.
