Yang Huaiyu didn't expect Yelu Renxian to take advantage of the fog to withdraw his troops, and when he got the news and sent someone to check, he found that the entire Liao army camp was empty, and what made Yang Huaiyu feel even more helpless was that because of the fog, he didn't dare to send someone to pursue him immediately, after all, Yelu Renxian was likely to take advantage of the fog to set up an ambush on the road, so he had to guard against it.

The winter in the north is easy to fog, this fog until the sun rises, the fog slowly disperses, until then Yang Huaiyu sent a cavalry to pursue, but Yelu Renxian has calmly retreated to Danzhou at this time, and then left an army in Danzhou City, and then withdrew in the direction of Ruzhou with a large army, which makes Yang Huaiyu want to pursue, he must first defeat Danzhou, but when they beat Danzhou, it is estimated that Yelu Renxian's army has fled back to Liao across the Great Wall.

Although they missed this opportunity to pursue Yeluren's army, Yang Huaiyu and they were not discouraged, because they had another chance next, that is, after Yeluren crossed the Great Wall from near Ruzhou first, he would definitely rush to the direction of Dadingfu to rescue, and then they just needed to pass through the north side of Gubeikou, so they only needed to wait for work.

At the same time, Zhao Yan's army, which besieged Dading Mansion, also cleaned up the surrounding cities and began to attack Zhongjing, but there were nearly 60,000 troops gathered in Zhongjing, even if the Song army had the advantage of artillery, I am afraid that it would not be able to be defeated in a short time.

However, Zhao Yan didn't want to take down Zhongjing, because he knew that even if he fought it now, he was afraid that it would be difficult to hold it, so this time Zhao Yan's decision to only recover the sixteen states of Yanyun was a very wise decision, and he could completely hold it there with the defense line of the Great Wall, as for Zhongjing, don't think about it, even if it can be held. In the future, it will also consume a lot of manpower and material resources, which is far from what the current Great Song Dynasty can afford.

It is precisely because of knowing the above that after Zhao Yan besieged Zhongjing City, he only carried out several tentative attacks at the beginning, creating an atmosphere of panic in Zhongjing and forcing Zhongjing City to ask for help from the outside. Then he stopped the attack and began to send people to contact Yang Huaiyu in Gubeikou.

Yelu Renxian's army retreated, and Yang Huaiyu did not stay in Gubeikou without moving, but immediately sent several troops to take back the Confucian Prefecture and other places occupied by Yelu Renxian before, and got in touch with Wang Shao in the rear, so that the sixteen states of Yanyun were once again mastered by the Great Song Dynasty, but there were still many loopholes in the Great Wall defense line at this time. Yang Huaiyu was temporarily unable to divide his forces to defend it, and Yeluren had first penetrated the Great Wall defense line on the Danzhou side.

After Wang Shao got in touch with Yang Huaiyu, he immediately breathed a sigh of relief, although he was a literati, but he also had a lot of experience in the art of war, when Yang Huaiyu was trapped before, he even wanted to personally lead the troops to rescue, but unfortunately he only had more than 10,000 troops left. Self-protection is not enough, let alone rescue.

The news of Yeluren's first withdrawal was also quickly reported to the imperial court by Wang Shao. As a result, this also made the sick Zhao Ji show a rare smile, and immediately let people spread the good news all over the world, and for a time the Great Song Dynasty, which made people's hearts fluctuate, finally stabilized a little, and even the riots in some places were also quelled, but the Manichaeism and the Western Xia in the northwest still did not subside, but intensified. This made Zhao Ji and the civil and military officials in the court also very headache.

Yeluren led the horse on the rugged mountain road, which was only three feet wide, and on the right hand side was a cliff ten thousand feet deep, and there was absolutely no chance of survival if he fell, but although this mountain path was dangerous. But it can bypass the Song army's defense line on the Great Wall, and the Great Song of Yelu Renxian reached the Sixteen Prefectures of Yanyun through here, and then besieged Yang Huaiyu's Great Song, but unfortunately now it is a failure, but it also makes them pay a lot of casualties.

Because it is impossible to ride a horse on the mountain road, even Yelu Renxian can only get off the horse and walk, the front and back of the mountain road are all dense soldiers, looking like a long snake marching in the mountains, from time to time there are gravel falling on the mountain, falling on the helmet clanging, occasionally frightened horses accidentally slipped from the mountain road, neighing and falling under the cliff, causing everyone to be nervous, and the feet involuntarily began to accelerate, wanting to get out of this mountain road as soon as possible.

After two marches, the army finally came out of the mountains, which also made Yeluren breathe a sigh of relief, and when the troops in the rear were also assembled, he just wanted to order the army to move forward, but finally received news from Zhongjing Dading Mansion that Zhao Yan's army had besieged Zhongjing and asked him to go to the rescue.

Although Yeluren had been mentally prepared before, but when he saw Zhao Yan personally leading tens of thousands of troops to besiege Zhongjing City, he couldn't help but be surprised, no wonder the team transporting grain and grass did not arrive during this time, it turned out that Zhongjing had been surrounded by Zhao Yan, and the grain and grass stored in the surrounding cities were estimated to be cheaper than the Song army, and the news could not be transmitted, let alone grain and grass.

After receiving the distress document from Zhongjing, Yelu Renxian has also been thinking about whether he wants to go to the rescue, because he is worried that this is a trap of the Song army, if he goes to the rescue, in case Zhao Yan and Yang Huaiyu of Gubeikou besiege his army, I am afraid that he will not be able to escape the fate of destruction.

However, before Yeluren made a decision first, Yelujun in Shangjing had already made a choice for him, and several holy decrees urged him to go to rescue Zhongjing, and now Yeluren couldn't think about it first, because Zhongjing City was of great significance, if even this place was conquered by the Song army, the blow to Da Liao would be extremely serious.

So in this case, Yelu Renxian had to order the army to kill in Zhongjingcheng, after seven days of emergency marching, Yelu Renxian's army finally came to the south side of Gubeikou, for this journey, Yelu Renxian was also very careful, because he knew that Yang Huaiyu would definitely not let them pass easily.

It's just that to Yeluren's first expectation, the scouts he sent to inquire about the situation soon came back to report that the Song army in Gubeikou showed no signs of going out, but instead added a lot of guards to the city, looking like they were waiting for them to attack Gubeikou from the north.

Originally, after Yeluren heard the report of the Tanma, he thought that it was the soldiers at the head of the Gubeikou City who made a gesture, but in fact, the army in the city had been ambushed on the way forward, so he immediately sent a large number of Tanma to check, hoping to find Yang Huaiyu's ambush in advance, but no matter how many Tanma he sent out, he did not find any signs of ambush.

"Third brother, what's going on, could it be that the Song army didn't set up an ambush in front of it at all?" In the camp of the Liao army, Yelu Zhixian also asked Yelu Renxian with a puzzled face.

"Impossible, Yang Huaiyu is not an ordinary person, he will definitely not let us leave smoothly, so I think there must be an ambush ahead, but we haven't found it for the time being!" Yelu Renxian said with a determined look.

"King Song, after we leave the sixteen states of Yanyun, Yang Huaiyu will definitely send troops to clean up the mess of Yanyun Shizhou, and also stabilize the hearts of the people, all of which need to occupy a large number of troops, so the lower officials think that there may not be many Song troops in Gubeikou, so it is not enough to ambush us at all, but to guard against our attack, the Song army at the head of the city has strengthened the guard, which is also in line with this explanation!" At this time, Xiao Huliduan, the concubine of the Liao State, also stood up and said that the highest of his envoys was now responsible for urging Yelu Renxian's army to go to Zhongjing to rescue.

Hearing Xiao Weiliduan's words, Yelu Renxian also showed a contemplative expression, but soon he shook his head and said: "I don't know anything, the facts have priorities, although the situation in the sixteen states of Yanyun is important, but compared to the elimination of our troops, it is nothing, Yang Huaiyu, as the commander, can definitely distinguish the severity, after all, for him, the credit for eliminating us is much greater than the credit for stabilizing Yanyun." ”

"Then what does King Song think we should do, we can't just stay here because we can't find the ambush of the Song army, you must know that Zhongjing is still surrounded by Zhao Yan's army, and it may be broken at any time!" Xiao Liduan said a little unhappily at this time, because he felt that Yeluren seemed to be saying that he couldn't tell the difference between the important and the heavy.

Yelu Renxian also heard that Xiao Wei's tone was wrong, but he didn't care, he thought about it for a while and spoke again: "Of course you can't just do this and wait, tomorrow I will send an army to try to attack the north wall of Gubeikou, and then we will know the reality in the city, if Yang Huaiyu's army is really in the city, we can leave with confidence!" ”

Hearing Yelu Renxian's strategy, all the generals in the army also praised it one after another, and even Xiao Liduan had to admit that Yelu Renxian was worthy of being a veteran in the army, and he thought of a countermeasure in such a short period of time.

Early the next morning, Yeluren first sent an army of about 10,000 people to try to attack the north side of Gubeikou, but was attacked by the fierce counterattack of the Song army at the head of the city, killing and wounding many people, and the general of the Liao army also saw Yang Huaiyu standing on the head of the city to supervise the battle, and even in the end the Song army also opened the city gate and took the initiative to attack, almost leaving their 10,000 troops under the city of Gubeikou.

Seeing such a result, Yelu Renxian was finally sure that Yang Huaiyu's army should still be in Gubeikou City, so that there could be no more ambushes on the road, which also made him finally put his mind at ease, led the army through the area on the north side of Gubeikou, and sure enough, he didn't see any ambushes, and then after a few days of urgent marching, they finally came to Bei'anzhou, according to the news they received before, this place was not defeated by the Song army, they could go into the city to rest, and at the same time, their food and grass materials were not much, and they needed to go into the city to replenish, Otherwise, even if it was until Zhongjing City, it would not be able to fight with the Song army.
