Climbing over the nearby mountains makes the road even more difficult. But even so, everyone did not complain, held a fire in their hearts, and moved forward silently, and finally turned over from the mountain after nearly an hour. By this time, it was already completely dark. On the one hand, Shao Zisong sent more men south to investigate the situation so that the army could advance safely, and on the other hand, he accelerated the speed of the march.

However, Murong Trai did not come to ambush them again, mainly because his energy was completely focused on Changshan Pass.

After all, if this place cannot be taken, and the ambush against the Tang army halfway is not likely to succeed because of the warning in advance, it is better to go directly to take Changshan Pass with a higher success rate.

The defenders of Changshan Pass were only 1,000 people, and Yao Chang and others, who had persisted for a day in the face of internal and external attacks, were already very tired. The Yan army inside and outside the gate seemed to have made contact, so the attack became more and more violent.

Seeing the soldiers around him fall one by one, there were many places, and the soldiers of the Yan Army had already climbed the battlements, and Yao Chang's heart couldn't help but sink.

"General, if we continue like this, I'm afraid we won't be able to support it!" A deputy general ran over to report.

"If you can't hold it, you have to hold it, we are here is the south entrance of the Flying Fox, if it is lost here, it will inevitably affect the Guangchang County behind, and even endanger the entire situation in Bingzhou. Tell everyone, even if you die, you have to die in the city! Yao Chang took a deep breath and said in a deep voice.

"Yes! The last general is going to deliver the order! The deputy general hurriedly responded.

Yao Chang has led the army in the Tang army over the years, but he has learned a lot. Otherwise, according to the current situation, with the way he was in the past, I am afraid that he would surrender directly. But after many years in the Tang Army, his feelings for Datang are already different.

Moreover, even if he really wanted to surrender, I am afraid that these generals and soldiers below would not follow. Therefore, the best way is to stick to it and wait until Shao Zisong's reinforcements arrive.

Yao Chang was very sure of this, he knew that Shao Zisong would definitely come. After all, everyone knows the importance of Changshan Pass, and it is impossible for him to leave it lost here. The arrival of reinforcements is only a matter of time.

In the pass, it had been two or three hours since the soldiers under Murong Chui attacked the wall, but there was no progress at all. The main reason is that Yao Chang deployed early, which made them lose the meaning of the raid.

And under the strong attack, he does not have a lot of troops in his hands, and if he lacks enough equipment, where is it so easy.

The longer the time dragged on, the more uncertain Murong Chui became, because he knew that it was impossible for the Tang army to let himself continue to attack on this side. For this reason, he had to urge his soldiers to attack the city many times, and strive to capture the pass as soon as possible.

However, in the middle of the night, his worst fears came true.

"Report, King Qiyu, there is a Tang army from the north and is coming towards us!" The scout ran back to report.

"It's time to come! Summons the order to go down and withdraw! When Murong Trai heard this, he couldn't help but glance back at the north, only to see a dark area over there, all of which were the figures of the mountains, but he knew that the Tang army was coming from that direction. After a moment of silence, he ordered directly.

"Withdrawal? King, isn't it a pity if we withdraw now? As long as we are given some more time, this Changshan Pass may be taken! When the time comes, what will happen even if the Tang Army arrives? A general beside him was surprised.

"It's too late! The troops in our hands are too small, and once the Tang army at the head of the city knows that the reinforcements from outside the city have arrived, the morale of the army will definitely be greatly boosted, and the resistance will be even stronger. It's impossible for us to take this place. While the Tang Army Brigade has not yet arrived here, let's withdraw first, and then we can save ourselves! Murong Chui shook his head lightly and sighed.

Hearing this, the crowd did not refute it anymore. Soon, the soldiers of the Yan Army who were attacking Guancheng withdrew from under the wall one after another. It didn't take long for all of them to disappear.

At the head of the city, Yao Changzheng led the army to resist the attack of the Yan army outside the city.

"General Qiyu, the enemy troops outside the north gate have suddenly retreated!" Some soldiers ran up to report.

"Huh? They ran away? Are you sure it's a real withdrawal, and not some kind of trickery? Yao Chang was stunned for a moment, and then asked.

"The little one can see it clearly, those people have run to the mountains to the west, and now they are completely gone."

"In that case, it should be our reinforcements arriving! Don't let your guard down yet, continue to guard the city, and if reinforcements arrive, report to me again! Yao Chang suddenly understood, and after thinking about it for a while, he explained.

"Yes!" The soldier hurriedly ran back.

It didn't take long for Shao Zisong to lead people to kill the city. At this time, he had already received the report and knew that the Yan troops who came by the detour had already retreated. This news made him breathe a sigh of relief temporarily, at least, the threat from Changshanguan's side was much less.

Yao Chang knew that after Shao Zisong arrived in person, he hurriedly ordered the door to open the door and welcome them in. With the addition of more than 1,000 people, Changshan Pass suddenly became stable.

Shao Zisong ordered the soldiers who were already exhausted to be replaced, and he discussed the battle situation with Yao Chang.

"According to the injured Yan Jun, it was Murong Chui who came on a detour this time. He personally led an army of 1,000 people, and after Xiaodao outflanked Changshan Pass, he originally planned to quickly solve the soldiers and horses that rescued Changshan Pass, and then come back to attack Changshan Pass. However, our soldiers were brave and good at fighting beyond his imagination, so he finally had to order the fire and rush to Guanbei to attack this place first. Yao Chang introduced.

He was also heartbroken when he heard the news that a thousand soldiers had died in the valley. Especially after hearing that there is no survivor at this moment, I am even more angry! After all, putting aside the comrades, they died to rescue their own people!

"Murong Chui! Hmph, such a blood feud will be settled with him in the future! Shao Zisong snorted coldly.

Fortunately, one wrong step was the wrong step, and he expected the wrong step, which eventually led to all the plans going wrong. So, this time he returned in vain. Moreover, after this incident, it will not be so easy to sneak attack us like this in the future. ”

"It's a lesson, and it seems like we were a little too careless in the past. The problem now is to defeat these enemy forces first. However, this matter will not end like this, I have already rushed to report to His Highness and ask him to give the order to attack Yan Kingdom! Shao Zisong said in a deep voice.

"The general's words are reasonable, if this is the case, let's deal with the enemy army outside this pass first!" Yao Chang also agrees with this idea.

After the two discussed it, they soon began to act and began to counterattack the Yan army outside the pass.

At the same time, Liao Chuan, who was in the military capital, had already received Shao Zisong's official letter. After knowing what had happened to him, he immediately changed his previous approach of pure defense and began to actively attack from his army.

After receiving Shao Zisong's letter, Liu Xiaohai immediately ordered Shangdang, Leping, Xinxing and other counties close to the Taihang line to raise their guard.

Moreover, from Fukou, Jingcheng, Malingsai and other places, they have sent troops to attack various defensive passes in Yan State.

For a while, the entire line of Taihang Mountain became lively. Tang Yan and the two sides, who had just been quiet for less than a year, seemed to be going to fight here again. The news spread back to Chang'an and Yecheng, and the imperial courts on both sides were involved in this matter.

Li Xin had nothing to say on his side, and as soon as he heard that the Yan army had taken the initiative to attack, he immediately ordered to mobilize troops from other places to the front line of Taihang. As a result, a lot of Tang troops were deployed on the west side of the entire Taihang Mountain, forming a situation of heavy pressure on the Yan State.

But this is not the main thing, the most important point is that Li Xin sent an envoy to Yecheng to question Murong Ke about sabotaging the peace negotiation.

The people who went this time didn't have anything good to say, almost pointed at their noses and scolded Yan Guo's civil and martial arts, and they also gave an ultimatum when they left. If you don't give Datang an explanation, Datang will have to do its best to march east and south.

Murong Ke felt that they were more wronged, because this time, these people in Yecheng didn't know about it at all. It was only after the battle broke out that Murong Chui sent someone back to report the incident.

"Confused, King Wu is too impulsive this time. The dispute between the two countries, which was finally settled, was stirred up like this! Even if he has a good plan, he has to see the timing! Now that the national strength has not been restored, the people have finally gained a little time to recuperate, and then they have to face a national war, isn't it in danger? In the palace, after Murong Ke saw the envoy of the Tang Dynasty, he said angrily on the spot.

"At this point, what should we do? Datang is now clear that he wants to be unforgiving! If we can't come up with an explanation, I'm afraid a war between the two countries is inevitable! Feng Yi asked.

"Alas, there will be a war between Tang and Yan in the end, but this king has always hoped that the time of this big war can be delayed. With the current situation, we have no chance of winning! Moreover, after pacifying the Dai State, the Tang army is now mighty, and in the past year, the strength of the army has more than doubled. It would be unwise to start a war at this time! Murong Ke also felt a headache and sighed.

"Alas, if we bow our heads to Datang, we are afraid of hurting our morale and frustrating our army. If you don't give Datang an explanation, under the rekindling of the war, there will inevitably be heavy casualties! Yang Lu also felt very embarrassed.
