In terms of Yan Jun's actions, Li Xin also couldn't understand why Dai Guo had been sending troops for nearly half a month, but Yan Guo seemed to be nothing? What he didn't know was that Murong Ping of Yan County had actually been waiting for news all along, waiting for a favorable opportunity.

And this so-called favorable opportunity refers to the fact that Murong Wen led the army all the way west from Pingzhou, and then killed all the way from Saiwai to Shanggu County, and finally hit the military capital of Shanlai.

Murong Wen's troops and horses were originally secretly dispatched, and their purpose was to be fast. Their goal is to take Juyong Pass in the fastest time as soon as possible, so as to disrupt the deployment of the Tang army in Shanggu County.

As long as the military capital is in chaos, Murong of Yanjun will take the opportunity to attack the military capital pass, and under the situation that the two sides work together, they have a great certainty that they can take the military capital back.

As long as the military capital is in hand, the rest of the place is basically unlikely to block the army of Yan State.

At that time, if the Yan army invades on a large scale, if the battle goes smoothly and the speed is fast enough, it will be able to fight all the way to the edge of Shengle City in less than ten days, and join the soldiers and horses of the Daiguo. At that time, if the coalition forces of the two sides go south together, they will be able to form a huge threat to Datang.

However, the idea is very good, but unfortunately the reality is a little too harsh. The first is that Li Xin's dispatch speed was too fast, and he didn't wait for Murong Wen to start a war at all, and he was already fighting fiercely with Daiguo.

The other one is that Murong Wen made his own decision, and the soldiers and horses suddenly changed their route to support Shi Yiqian when they entered the middle of the road. Otherwise, the current battle situation in the Northland area may be far from being so simple.

Murong commented that they had been thinking about the response in the north, but they didn't wait for the news of the chaos of the Tang army in the north. On the contrary, Murong Wen, who finally escaped back to Pingzhou, sent someone to deliver the news of the failure at this time.

"Stupid! It is simply stupid to dare to change the order of the general, rush to support Shi Yiqian, and ignore the overall situation! In Yecheng, Murong Ke, who was originally preparing in secret, waited for such an official letter, and his mood can be imagined.

Originally, he was a person who was moody, but at this time, he remade it a few times on the table in a row, and he was obviously already angry in his heart.

"Your Excellency! This move by the king of the belt seems to be a last resort! After all, at that time, Shi Yiqian was already at the critical moment of defeat, if it could not resist the Tang army, I was afraid that our 30,000 army would not be able to take the military capital! Yang Lu persuaded from the side.

"Alas, I regret that I should not have sent him to lead the army! If not, how could it be! If Shi Yiqian did not have the support of these 30,000 troops, I am afraid that he would not fight the Tang army to the death. If he retreats north directly, won't the Tang army have to chase him? At that time, didn't Murong Wen just take the opportunity to attack the military capital? It doesn't take long, as long as there is a day or two, it is enough to make the Tang army in the military capital of the army feel confused! Alas, the erection is not enough and conspiracy, and the ancients are honest and do not deceive me! Murong Ke sighed and said.

What he meant by this also meant that Murong Wen was still too young, otherwise, any older general would not do this.

After all, the overall situation is there, no matter how Shiyiqian wins or loses, as long as he can open the military capital and let the army go north, everything will not be a problem!

However, a plan that he carefully prepared and secretly made a lot of preparations for this. In the end, because of a young boy, the plan was already over at the beginning.

Not only that, but the most hateful thing is that after this battle, there is no longer any force in the northern territory of the Tang Dynasty that can contain them. Once the Daiguo was defeated, it would not only affect the Tang Dynasty, but the overall situation of the whole world.

A capable person like Murong Ke can naturally see the key at a glance.

"It's been here, and it's useless to talk about it! What we have to worry about now is whether Li Xin will take the opportunity to go south. If that's the case, we'll have to be ready! Feng Yi persuaded on the side.

"Yes, at this time, Dazai-sama needs to make an idea!" Yang Lu also chimed in.

"Nowadays, it is impossible to make progress. The only way to do this is to let the soldiers and horses in all parts of the line raise their vigilance and strengthen their precautions. As long as we are ready and don't have problems ourselves, presumably Li Xin will not be too easy to get out of the way! After hearing this, Murong Ke calmed down for a while, and after a deep groan, he said.

"Okay, I'll go and draw up an edict, and then order someone to send it to the generals from all over the country!" Feng Yi nodded.

And just when Murong Ke and the others raised their vigilance, Li Xin finally came to Shanggu County again. After leaving the army here, he led Deng Qiang and other generals, as well as hundreds of personal soldiers, to the military capital.

In the two passes of today's military capital, there are 1,000 men and horses guarding each other. Because the military capital pass in the south and the Yan army often fought large and small, therefore, in the valley between the two passes, there were still 1,000 men and horses left behind for the purpose of responding and rotating at any time.

In order to cope with the attack of the Yan army, Liao Chuan sat in the military capital almost all the year round. Hearing that Li Xin was coming lightly, he hurriedly went down to Guancheng to greet him.

"The last general will meet His Highness!" All the generals and soldiers saluted!

"Excuse me! At the moment of the great enemy, everyone has worked hard! Li Xin glanced at everyone, and then said.

"Your Highness!" Only then did Liao Chuan and the others get up.

"In the past few days, has the Yan army made any changes?" Li Xin walked forward, slowly ascended to Guancheng, and asked Liao Chuan beside him.

"Generally speaking, it's not much different from before, if there's any difference, it's that there seems to be a lot less attack these days. In the past, there was a small attack in three days and a major attack in ten days. But in the past few days, there has not been a single attack, and even the soldiers and horses have retreated several miles to the south! ”

"It seems that Yecheng has already received the news of our great victory over Daiguo! In particular, the defeat of Murong Wen's soldiers and horses directly led to the collapse of their plan. At this time, they retreated, I'm afraid it was to better guard against us! Hearing this, Li Xin thought about it slightly and understood the trick.

"Now that the threat of the Daiguo has been lifted, are we going to attack Yandi immediately?" Liao Chuan asked.

"It's not that easy! Let's not talk about the number of battles between us and Daiguo, although they are all big victories, but there is still damage after all. Coupled with the fatigue of the soldiers, it is not a good thing to start a war with the more powerful Yan State at this time. What's more, a generation of countries has not yet been completely resolved, and sending troops to attack Yan at this time may not be able to achieve much benefit, this kind of thing is still not good! Li Xin shook his head and vetoed the proposal.

"Yes! Although Yan Guo has been defeated many times in our hands, it has not reached the point of breaking bones. In addition, now that Henan and other places are in a stalemate, if we get out of the customs at this time, it will become a separate battle between us and Yanguo! Liao Chuan also has a clear understanding of this, so he agrees with the idea of not going to war.

"Yes! Yan Guo is a behemoth, and Dai Guo is nothing compared to it. We will inevitably have a battle with Yan Kingdom, but the time for this battle has not yet come, and we ourselves are not ready. Small battles are especially acceptable, but big battles require caution. The army is easy to send and difficult to collect, once the big war starts, we must destroy the enemy with one blow! Li Xin said slowly.

It is said that the emaciated camel is bigger than the horse, and the Yan Kingdom has not lost too much now, let alone to the point of death. Even if Datang has been growing stronger, he doesn't dare to say that his strength has surpassed Yan Guo until now.

Therefore, once the war of annihilation begins, it will inevitably have a huge impact. Datang must win in one fell swoop, and it must be a big victory.

Otherwise, if you kill 1,000 enemies and lose 800 yourself, even if you win in the end, Datang will face an extremely unfavorable situation.

After all, the world is not peaceful, and there are tigers and wolves around!

Li Xin came to inspect the military capital, and after seeing that there were basically no big problems here, he comforted the soldiers stationed here, and then prepared to rush back to Chang'an. After all, he, the Tang King, should not stay outside for a long time, otherwise, the people's will will be easily confused.

In mid-May, it is the summer harvest season. When he led the Bupo Army and the Flying Dragon Cavalry to Jinyang County, a sudden incident made him have to stop.

"When did this happen?" In the official office, Li Xin saw Liu Xiaohai, who came in person, and after seeing the letter, he couldn't help frowning.

"Two days ago, it was a rare opportunity to follow what the letter said. We have always relied on Taihang Mountain to defend, which is certainly conducive to our defense against the Yan army, but now that the offensive and defensive momentum has changed, this Taihang Mountain has become our imprisonment. At this time, the other party sent a letter, and for us, it was just the right place to make things happen! Liu Xiaohai replied.

"The proposal is good, but whether this thing can be done or not, then it is not good! Lu Hu has been swaying from all sides. Although he is an official of Yan State on the surface, he is actually always self-reliant. Whether such a person can be trusted is really doubtful! Li Xin thought for a moment and said slowly.

This letter was not written by Liu Xiaohai, but written by Lu Hu to Li Xin. There is nothing else in this letter, but it says one thing, and that is conversion! Lu Hu said that he was willing to submit to the Tang Dynasty, and more importantly, he was willing to lead the Tang Dynasty soldiers and horses to attack Yedu from Hanoi to the front.

Not to mention how feasible this plan is, if it can really succeed, it will definitely be a huge blow to the entire Yan Kingdom.
