"Reinforcements have arrived!" This news spread throughout Gubeikou at a blink of an eye, and for a time all the Song troops were in high spirits, and the depression caused by the long-term siege was also swept away, and the declining morale immediately became very high, and even many generals asked for battle, preparing to attack the Liao army outside the city with reinforcements.

Yang Huaiyu was also very happy, this afternoon, a hot air balloon floated down the wind from the north, and then landed in the city, the messenger was immediately brought to Yang Huaiyu, and it was from the other party's mouth that Yang Huaiyu knew that Zhao Yan's army had captured Yingzhou and Yuguan, and all the way to Zhongjing Dading Mansion to kill, and Dading Mansion was the general rear of Yeluren's army, and now the rear is in chaos, Yeluren can't retreat first.

"Chief, are we closely monitoring the situation of the Liao army camp, if they retreat, then it will be our chance!" At this time, Hu Yanqing also suggested to Yang Huaiyu with an excited face, if Ye Luren retreated first, the morale of the army would definitely fluctuate, and if Yang Huaiyu and they took the opportunity to cover up, it was likely that the Liao army would be defeated.

Yang Huaiyu also thought of this opportunity, thought about it for a moment and nodded: "Zhongjing was attacked by the army of His Royal Highness King Yue, Yelu Renxian will receive the news in the next few days, and then their logistics will also have problems, so if we can find the right opportunity, maybe we can leave all of Yelu Renxian's army in the land of Yanyun!" ”

"Yes! This will be arranged! Hu Yanqing was also very excited, they have been besieged by Yelu Renxian's army in the past few months, although the other party has not been able to do anything to them, but it also makes them feel very breathless, so for this rare opportunity, Hu Yanqing and they will naturally not give up.

Seeing Hu Yanqing leaving, Yang Huaiyu immediately summoned other generals. Then issue one general order after another, arrange for the army in the city to prepare, if there is any change in the army of Yelu Renxian, the army in the city will immediately kill out of the city, even if it cannot completely annihilate the army of Yelu Renxian, it will bite off a few bites of flesh from them.

With one order after another, the order was conveyed. The Song army in Gubeikou also immediately boiled, and the entire Gubeikou was like a fierce beast that had just woken up from hibernation, polishing its minions, and would launch a fatal blow to the Liao army outside the city at any time.

At first, he thought that the Song army in the city was running out of food, so he was ready to fight to the death, and he also made corresponding arrangements for this, and decided that the Song army could not break through no matter what. However, he slowly found that the Song army in the city did not take the initiative to attack the city. On the contrary, they stepped up the monitoring of his side, for example, the hot air balloon rising in the city never broke from morning to night, and even at night, there were special people standing on the head of the city to observe their side.

Yeluren was a veteran in the army first, and when he was young, he had crawled out of the pile of dead on the battlefield several times, and he had a beastly intuition about danger, especially now through the various manifestations of the abnormal activities of the Song army, which made Yeluren feel very bad, like being targeted by a fierce beast. There is a feeling of hair all over the body.

It is precisely because of this that Yelu Renxian even had the idea of withdrawing his troops immediately. However, he also took into account Yelujun's suspicion of himself, originally the other party was worried that he would not be able to catch any tricks on his own, if he withdrew from the army for no reason this time, he would definitely be charged with escaping from the battle, and his reputation would also be in vain.

After weighing the weight, Yeluren had to choose to stay hard. However, he did not sit still, and immediately flew out countless scouts to inquire about the situation, hoping to find the source of that dangerous feeling, but before those scouts could send news, news came from Ruzhou and Danzhou, which had been attacked by him before. The army escorting grain and grass in the rear did not arrive within the time limit, and the people sent out to contact the rear did not return, and the guards of Ruzhou and Danzhou felt abnormal, so they quickly reported to Yelu Renxian.

Hearing the news from the rear, and then thinking of the movement of the Song army in Gubeikou, Yelu Renxian immediately broke out in a cold sweat, he has always been very strict with the army, and the army escorting grain and grass will never dare to delay, after all, it is a crime of killing the head, but now the team escorting the grain and grass has not arrived, this must have happened a great change in their rear, and the Song army in Gubeikou is extremely active, which shows that they must have received some good news, under the combination of these two news, Yeluren's first thought was that the reinforcements of the Great Song Dynasty arrived, And the other party's reinforcements are likely to go around to their rear to draw a salary, Yang Huaiyu must be waiting for his side to cause chaos in the army because of the lack of supplies, and then the Song army will definitely give itself a fatal blow.

Thinking of the above, Yeluren immediately decided to withdraw his troops, and as for whether Yelujun would be guilty because of this, he couldn't care about it, after all, if he hesitated any longer, all the nearly 100,000 troops under his command would have to stay here. However, although Yelu Renxian was anxious in his heart, he still kept calm, he knew that if he showed a little sign of retreat, the Song army in Gubei's mouth would definitely pounce on him like a hungry wolf, and even if he couldn't keep his army, he was afraid that he would suffer heavy losses, and even he himself was likely to be in danger.

It is precisely because of this that Yelu Renxian still kept the army as it was on the surface in the next few days, and even carried out a tentative attack on Gubeikou, seemingly ignorant of the changes in the rear, but secretly preparing a retreat plan, hoping to hide it from the eyes of the Song army.

I have to say that Yelu Renxian is scheming, his withdrawal plan is very thorough, although Yang Huaiyu and Hu Yanqing and others in the city have sent people to monitor day and night, but they didn't even find that Yelu Renxian was preparing a retreat plan, and even they were confused by some of Yelu Renxian's actions, and they didn't know if Yelu Renxian already knew about the changes in the rear, let alone whether he was going to prepare to retreat?

Just when Yang Huaiyu and others were confused by Yelu Renxian's methods, suddenly on a foggy morning, the Song army guards on the city wall of Gubeikou suddenly felt that something was not right, because the Liao army camp opposite was too quiet, although the military discipline of the Liao army was very strict, but in a huge military camp every morning, there must be a lot of noisy sounds, and it could be transmitted to the city along the wind, and it would definitely not be as quiet as today, just because there was a heavy fog in the middle of the night last night, and there was no figure three steps away. Not to mention looking at the Liao army camp miles away. (To be continued......)

PS: There are too many things in the past few days, this afternoon Lao Yu went out for an afternoon again, and came back at almost six o'clock, hurriedly coded 2,000 words first, and then made up the remaining 1,000 words when he was free.
