There is an idiom called "Lost in the east, harvested in Sangyu", which is very appropriate for Yang Kefu, who is leading the army to kill the suburbs of Shenzhou at the fastest speed. Although the desperate struggle of Xingu and Tunnu and others and the fight back made Yang Ke's hope of resurrecting and capturing Yelujing and building an immortal achievement. However, it was precisely because of this sudden incident that the remnants of the Khitan Army fell into chaos, and they could not allocate the camp at dawn and continue to rush as originally planned. As a result, Yang Kefu's department, which was not likely to catch up with the former before he arrived in Liaoyang City, finally had a chance to catch up with the opponent who had escaped several times.

In fact, while Xingu and Tunnu rushed out of the camp outside the camp of the Khitan army in the suburbs of Lejiao in Shenzhou and fled for their lives in a hurry, the Khitan civil and military ministers, generals and guards in the camp also fell into chaos due to the sudden death of Yelujing - because of this, Xingu and Tunnu had a chance to escape.

Because Yelu Jing has no direct descendants, and he did not officially designate an heir to the throne during his lifetime, and this time he was assassinated outside the city of Lejiao in Shenzhou and died very suddenly, so several powerful people in the Khitan royal family were interested in winning the dragon chair. Because at this time, there were less than 8,000 soldiers and horses following Yelu Jing's side, so that the strength that each Khitan royal family who wanted to compete for the throne could control was very limited, and no faction could occupy an absolute advantage, so as to completely suppress all other opponents. Therefore, in this case, an alliance with each other is a last resort but inevitable choice for these people. As a result, after some co-optation, tandem coercion, inducement, compromise, and concession, a group of Khitan royal forces formed two factions represented by Yelujing's favorite nephew Yeluxian and the emperor's brother Yelugang Sage.

In the past, when the two factions were formed, a life-and-death battle for the throne would have been staged. However, at this time, none of the two forces competing for the position outside the city of Lejiao in Shenzhou dared to act rashly. First, there is not much difference in the strength of the two sides. Yeluxian's side gathered a group of ministers led by Yeluwu and nearly 5,000 soldiers and horses. On the other hand, Yelu Sage co-opted his younger brother Yelu Bishi and Yelu Huge, who was rejected by the ministers due to the poor performance of the previous battle of Yanjin City in Yinzhou, and a group of civil and military forces with the main force, as well as more than 3,000 soldiers mainly from the remnants of Yelu Huge's command; Second, with 5,000 against 3,000, although from the perspective of the comparison of troops, Yeluxian's side has a certain advantage, and it seems that there is a certain certainty of the final victory. But the problem is that now that the Zhou army is chasing behind him, once Yeluxian's side can't fight quickly, when the Zhou army arrives, he will say what the throne is, but I am afraid that he and a group of civil and military generals will not even be able to save their lives. Thirdly, even if Yeluxian was sure that he would defeat his rivals in a very short period of time, his losses would be very severe when the forces of both sides were about the same. When the time comes, even if he can retreat to Liaoyang City. In the face of Yeluxian, who is likely to have only two or three thousand soldiers and horses in his hands, and he is not in the right position, who can guarantee that Liaoyang, who has an army of 30,000 in his hand, will not have other thoughts in his heart. After all, although Yelu Heli is not a descendant of Taizu, his ancestor is a cousin of Taizu, and he is also a member of the royal family. Therefore, unless it is a last resort, Yeluxian, who is on the dominant side, is not willing to compete with his cousin Yelugang Sagar now.

Yeluxian, who was in an advantageous position, was reluctant to do anything, and Yelugang Sage, who was in a disadvantageous position, did not intend to fight with his cousin and nephew, and completely lost his opportunity to compete for the throne. Therefore, after the confrontation between the two sides for a long time, Yeluxian took the initiative to send an envoy to him to send him an invitation to conduct reconciliation negotiations, and Yeluxian immediately accepted it. So, at the beginning of the rising sun, the negotiators of the two sides sat in a tent in the center of the camp with the construction and bottom line of their respective chiefs, and began to discuss the imperial throne and the arrangement of power between the DPRK and China. After some bargaining, compromise and concession, the two sides finally reached an agreement on the final agreement near noon, which was signed and confirmed by the leaders of both sides.

According to this agreement, Yeluxian succeeded him as emperor, and Yelugang Sage was canonized as the emperor's uncle at the same time as the king of Qi from the king of Taiping. In other words, if Jeruxian died and Jerush Sagar was still alive, the latter, not the former's heir, would succeed him.

Although the old emperor died, it was not uncommon for his son to fail to succeed to the throne and his younger brother succeeded him in the history of dynasties and Khitans - Yeluxian's father, Sejong Yelu Ruan, died in a rebellion, and the emperor was succeeded by his uncle Yelu Jing, the main force of the counterinsurgency, rather than his own son. But the problem is that except for the reign of Li Yan of Tang Wuzong, who was manipulated by the palace eunuchs to officially canonize his uncle Li Chen as the emperor's uncle, other uncles who became emperors either usurped the throne or took advantage of the chaos to seize the throne. On the one hand, it is certainly because of the compulsion of the form, and in the case of strict external troubles and potential internal worries, it is a compromise method that has to be adopted. On the other hand, I am afraid that it is also due to Yeluxian's weak health, not only is it impossible to live long, but even the heirs may not be able to have children, Yelugang Sage feels that he has a great chance to succeed as the emperor and take over the imperial power.

However, no matter how unruly and deviant the act of the canonized imperial uncle is, and whether or not Yelu Sage's wishful thinking can become a reality in the future, in short, under the compromise and concession of the two competing parties, the remnants of the Khitan court finally gave up the confrontation and reunited their troops, and after requisitioning and transferring 2,000 defenders in the suburbs of Shenzhou to join their ranks, they took the remains of the former emperor Yelu Jing to set up camp, hurriedly left the suburbs of Shenzhou, and went all the way south to Liaoyang City, one hundred and fifty miles away. Prepare to make the last effort and struggle for the continuation of the Great Liao Guozuo.

It's just that although the wish is beautiful, the reality is extremely cruel. Soon after Yeluxian and Yelugang Sage set off with a group of civil and military ministers and more than 10,000 remnants, the thousand-man team responsible for the cover of the rear guard came with news that they had found that the Zhou army was chasing more than 1,000 people and horses, and they had already started a fight with the other party. Since half of the enemy army is the "Flying Dragon Army", the rearguard troops may not be able to hold on for long, so please send reinforcements as soon as possible. The Khitan monarchs and ministers were shocked when they heard the news, and Yeluxian and Yelugang Sage led the crowd to accelerate their escape to the south, and on the other hand, they divided about 1,000 soldiers and horses to turn around and go north, and together with the rearguard troops, they blocked the advance of the Zhou army's pursuers, so as to buy enough time for the main force to evacuate.

With 2,000 Khitan remnants against one cavalry battalion each of the "Flying Dragon Army" and "Security Army", such a balance of strength originally had no chance of winning. It was only because the cavalry battalion of the "Flying Dragon Army" was unwilling to give up its strengths and advantages and engaged in close-range combat with the Khitan cavalry, thus increasing its casualties in vain. Therefore, in the face of the surging Khitan cavalry who launched a lifeless and decisive attack on their own side with the momentum of seeing death as home, the battalion commander of the "Flying Dragon Army" cavalry battalion did not hedge with the other side, but ordered the "Flying Dragon Army" cavalry battalion to form a formation on the spot to block it, and the "Security Army" cavalry battalion to swim on both flanks to cover it, so as to defeat this enemy army in front of him.

Although this tactical arrangement was conducive to the cavalry battalion of the "Flying Dragon Army" to give full play to its own advantages, it also slowed down its pursuit. Therefore, although relying on the ring defense formation, this Zhou army pursued the attack of the Khitan cavalry at a very small cost, and inflicted heavy casualties on the opponent, and finally the cowardly Khitan cavalry followed away less than 300 people. But they also paid more than an hour for this, and the distance between them and the main force of the remnants of the Khitan army has changed from less than five miles to nearly forty miles, and it is impossible to catch up before the other party escapes to Liaoyang City.
