"The reinforcements are here!" This news spread throughout Gubeikou at a blink of an eye. For a moment, all the Song army was energetic. The depressed depression caused by long-term siege was swept away, and the morale of decline immediately became very high. Many generals even 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 from the north with the wind and landed in the city. The messenger he was riding on was immediately taken to Yang Huaiyu. It was from the other party that Yang Huaiyu knew that Zhao Yan's army had captured Yingzhou and Yuguan, and he rushed to Zhongjing Dading Prefecture, and Dading Prefecture was the main rear of Yelu Renxian's army. Now there is chaos in the rear, and Yelu Renxian could not do it.

"Master, are we closely monitoring the situation of the Liao army camp? If they retreat, it will be our chance!" At this time, Hu Yanqing also suggested to Yang Huaiyu with excitement, if Yelu Ren retreated first, the morale of the army would definitely be fluctuating. If Yang Huaiyu and the others took the opportunity to cover up the killing, it would be very likely that the Liao army would be defeated.

Yang Huaiyu also thought of this opportunity. After thinking for a moment, he nodded and said, "Zhongjing was attacked by His Highness the King of Yue's army. Yelu Renxian will receive news in the next few days, and their logistics will also have problems. So if we can find the right opportunity, we may be able to leave all of Yelu Renxian's army in Yanyun's land!"

"Yes! Let's make arrangements for this!" Hu Yanqing said excitedly. 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, they also feel very angry, so they naturally won't give up on this rare opportunity.

Seeing Hu Yanqing leave, Yang Huaiyu immediately summoned other generals, then issued orders one by one, and arranged for the army in the city to prepare. If Yelu Renxian's army had any abnormal movement, the army in the city would immediately break out of the city, even if it could not completely annihilate Yelu Renxian's army. It would still take a few bites of meat from them.

As the orders were conveyed one by one, the Song army in Gubei's mouth immediately became boiling. The entire Gubeikou was like a ferocious beast that had just woken up from hibernation, polishing its minions and launching a fatal blow to the Liao army outside the city at any time.

Yelu Renxian also noticed the abnormal movements in the city. At first, he thought that the Song army in the city had not much food, so he was ready to fight to the death. He also made corresponding arrangements and decided not to let the Song army break out of the siege no matter what. However, he gradually found that the Song army in the city showed no sign of taking the initiative to attack, but instead stepped up surveillance on his side, such as the hot air balloons rising in the city never stopped from morning to night, and even at night there were special people standing on the top of the city to observe him.

Yelu Renxian was a veteran in the army. When he was young, he had crawled out of the dead on the battlefield several times, and had a beast-like intuition about danger. Especially now, through the various manifestations of the abnormal activities of the Song army, Yelu Renxian felt very bad, just like being targeted by a ferocious beast. He felt a sense of hair all over his body.

It is precisely because of this that Yelu Renxian even had the idea of ​​withdrawing troops immediately. However, considering Yelu Jun's suspicion about him, the other party was worried that he would not be able to catch any handle for him. If he retreated for no reason this time, he would definitely be charged with escape in the last battle. In addition, his reputation for life would be lost.

After weighing the pros and cons, Yelu Ren had to choose to stay with his teeth. However, he did not sit still and waited for death. He immediately sent countless horses to inquire about the situation, hoping to find the source of the dangerous feeling. However, before the news came from those horses, Ruzhou and Tanzhou that he had attacked before came from before, the army escorted food and grass in the rear had not arrived for a long time, and the people sent out to contact the rear were not returned. The guards of Ruzhou and Tanzhou felt abnormal, so they quickly reported to Yelu Renxian.

When he heard the news from the rear and thought of the unusual movements of the Song army in Gubeikou, Yelu Renxian was immediately scared and sweated. He had always been extremely strict in the army. The army escorting food and grass would never dare to delay the deadline. After all, it was a crime of beheading. However, the team escorting food and grass has not arrived for a long time. This must be a huge change in his rear, while the Song army in Gubeikou was extremely active, which shows that they must have received some good news. With the combination of these two news, Yelu Renxian was the first to think of the reinforcements of the Song Dynasty, and the opponent's reinforcements were likely to go around to his rear and drain the firewood. Yang Huaiyu must be waiting for his own side to cause chaos in the army due to insufficient supply of materials. At that time, the Song army would definitely give him a fatal blow.

Thinking of the above, Yelu Renxian immediately decided to withdraw his troops. As for whether Yelu Jun would be punished for this, he couldn't care. After all, if he was hesitant, his nearly 100,000 troops under his command would have to stay here. However, although Yelu Renxian was anxious, he remained calm. He knew that if he showed any signs of retreat, the Song army in Gubei's mouth would definitely pounce on him like a hungry wolf. Even if he could not keep his army, he might suffer heavy losses, and even he himself might be in danger.

It is precisely because of this that Yelu Renxian still kept the army as it was in the next few days, and even launched a tentative attack on Gubeikou. He seemed to know nothing about the changes in the rear, but secretly preparing for a plan to retreat, hoping to hide it from the eyes of the Song army.

It has to be said that Yelu Renxian is very scheming and his plan to withdraw troops is very thorough. Although Yang Huaiyu, Hu Yanqing and others in the city have sent people to monitor them day and night, they did not find that Yelu Renxian was preparing for the retreat plan. They were even confused by some of Yelu Renxian's actions. They were not sure whether Yelu Renxian had already known about the incidents behind, and they didn't know whether he was going to retreat?

Just when Yang Huaiyu and others were confused by Yelu Renxian's methods, suddenly on a thick foggy morning, the Song army guards on the city wall of Gubeikou suddenly felt something was wrong, because the Liao army camp opposite was too quiet. Although the Liao army's military discipline was very strict, there must be a lot of noisy sounds in a huge military camp every morning, which could be transmitted to the city head along the wind. It would definitely not be as quiet as today. It was just because there was heavy fog in the middle of the night yesterday, and there was no sign of people three steps away, let alone checking the Liao army camp several miles away.
