Murong Chui finally persuaded Yue Juan, who agreed to stay in Yan County and take charge of the war here. After the two discussed, Murong Chui quietly rushed to Changshan County with some people. The place where Changshan County is located, that is, the area north of Shijiazhuang and east of Wutai Mountain in later generations. It is said that Zhao Zilong is a native of Changshan, but in fact, he is a person from this place.

Next to Changshan County is the Zhongshan Kingdom, and now Murong Wei's younger brother Murong Chong is the king of Zhongshan, responsible for guarding his own kingdom.

After Murong Chui rushed to the territory of Shangquyang County, which bordered Dai County in the northernmost part of Changshan County, he began to prepare for action.

"King, everything is ready, just waiting for your order!" The general who came back to prepare first, reported.

"Very well, immediately prepare enough dry food for three days, and then the army will set off immediately!" Without further ado, Murong Chui immediately ordered.

That night, taking advantage of the hazy night, Murong Chui led a thousand brave men selected from the army to the north and plunged headlong into the mountains.

Changshan Pass was guarded by Yao Chang, and it was originally a small gate, and there was no need for a general of his level to sit in the town. However, since this place is at the forefront of the army, it may face a large-scale attack by the enemy army at any time, so it is especially important to pay attention to this place.

Not only here, but also the pass fortresses at the very edge of the country, such as Ngu Nguyen Pass, are basically the same.

There are 1,000 soldiers and horses stationed here in Changshan Pass, and if it is not limited by the terrain, in fact, more people can be put in. Together with the Wuruan Pass to the east, it forms a barrier to protect the county seat of Guangchang in the rear.

It can be said that these are the two gates of Guangchang County, guarding the main road into Guangchang County.

Guangchang County is located in a mountain basin, but because it happens to be the intersection of the two ancient Taihang roads of Flying Fox and Puyin, it is particularly important. Li Xin put Shao Zisong here to sit down, and at the same time stationed 5,000 men and horses here for a long time, responsible for planning the surrounding passes.

In addition to the two passes of Changshan Pass and Wuruan Pass, as well as Lingqiu Pass in the west, Feihukou in the north and other important places, Shao Zisong was responsible for leading tens of thousands of troops in this important area.

In the past, whether it was Changshan Pass or Wuruan Pass, once it was attacked by the enemy, Guangchang County would immediately send reinforcements to support. Because the distance is not too far, it is quite easy to reinforce.

That's why the Yan army attacked many times, but it was still impossible to take down these two important places.

A hundred miles west of Changshan Pass is Wutai Mountain, this place is a religious place, since the Eastern Han Dynasty began to build Buddhist temples. However, the wide mountain between it and Changshan Pass is still dense and steep.

After Murong Chui and the others entered the mountain forest, a day later, Yue Juan and Murong You, the king of Fanyang, officially began to attack Changshan Pass, Wuruan Pass and Jundu Pass according to the plan.

Since the Yan army has basically stopped attacking for nearly a year, this sudden dispatch really surprised Yao Chang and others. Still, there's nothing to be afraid of. In addition to reporting to Shao Zisong in the rear, they were defending as usual.

The frontal battle is unfolding, basically speaking, there is nothing special, and it seems that the Yan army does not seem to be very urgent. Although the attack was quite fierce at first, it was not enough to take down the pass.

But the further back it went, the more fierce the Yan army's attack became, and it was a big move to go down in one fell swoop, and swore not to give up. In this way, Yao Chang and the others felt a lot of pressure.

In addition to defense, he had to come to the rescue of Shao Zisong and asked for additional troops and horses to support the front line. After Shao Zisong received this report, he immediately ordered his troops and horses, preparing to send 1,000 men and horses to Changshan Pass and Wuruan Pass.

Between Changshanguan and Guangchang County, there is a mountain road dozens of miles long, and this road winds through the valley. At this time, on this mountain road, there is a force of more than 1,000 soldiers and horses hurrying towards the direction of Changshan Pass.

"Speed up, you must rush to Changshan Pass as soon as possible!" The deputy general who led the army gave a loud order, urging the army to move forward.

After hearing this order, all the soldiers sped up a few points on their feet.

"Boom!" There was a loud bang, just as the general's words fell, and then suddenly a cloud of dust and smoke rose from both ends of the mountain road.

"Not good! There is an ambush, everyone be careful! As soon as he heard this voice, the general who led the troops was stunned for a moment and then immediately reacted, and hurriedly shouted loudly.

After hearing this, all the soldiers took action one after another, and the fighting quality of the Tang Army was fully reflected at this moment. Even if they were suddenly ambushed, they did not panic immediately, everyone looked for a favorable position nearby to cover themselves, and then began to counterattack.

Between the trees on the top of the mountain, it was Murong Chui and the others who were in ambush.

Murong Chui's main goal is to take Guangchang County, because only by taking this place can he occupy enough initiative. Although Changshan Pass and Wuruan Pass must also be taken, the priority is to weaken the forces of Guangchang County first.

Attacking Changshan Pass and other places from the front, not only to cooperate with his own group of men and horses to make a detour to attack Guancheng, but also an important reason was to transfer the Tang Army garrison in Guangchang County.

Murong Chui thought about it very clearly, even if he went to take Changshan Pass first, if Guangchang County couldn't be taken, it wouldn't be particularly significant. But if you ambush halfway first and wipe out the Tang army reinforcements that went south to support Changshan Pass, then things will be much easier.

Solve the reinforcements first, and then turn back to capture Changshan Pass. In this way, the army from the south will be able to continue to the north and reach the city of Guangchang County.

As long as this passage is opened, the follow-up army can be divided into two parts. One part was to immediately encircle and attack the county seat of Guangchang, while the other part was to rush east to Wuruan Pass and take down Wuruan Pass.

If everything goes well, after the three places have been mastered, you can go north to capture Lingqiu Pass and Flying Fox Pass, and west to Lingqiu County and Bottle-shaped Village. If so, this operation was a complete success, and if the Tang Army wanted to recapture it, it would not be as easy as before.

After all, he is not Murong Ping, and he will not make such a mistake again.

At the beginning of the battle, everything was going well, and the Tang army reinforcements, as expected, were directly blocked in the valley and attacked by their own condescending. But soon, Murong Chui discovered an unexpected thing, that is, the combat effectiveness of the Tang Army far exceeded his expectations.

"King, look at it like this, it is definitely not an easy thing for us to solve these Tang troops below! If it is delayed for too long, I am afraid that the Guangchang County side will know the situation here, and once the other party comes to reinforce the army, we are afraid that we will fail! The general beside him couldn't help but feel a little embarrassed when he saw the situation in the valley below.

Murong Trai didn't answer, just looked at the valley with a calm face. After a long time, he said: "Under the sudden attack of the Tang army, it can still fight back calmly without hurry, it is really a fierce enemy!" If we were replaced, or even any soldier in the world, I am afraid that we would not be able to do this! From this point of view, Li Xin's training is really extraordinary! ”

Everyone knows that the soldiers and horses of the Tang Dynasty were trained by Li Xin himself from the beginning, and everyone has heard of that set of training methods. Although they have not seen it with their own eyes, everyone knows that it is very different from the training methods of the world!

Although Li Xin rarely leads the troops to train in person now, the Tang Army has already deeply imprinted him from top to bottom. No matter how many times ~ has been perfected and adjusted later, the core spirit of the training system actually comes from Li Xin.

I thought it was just a small battle that could be ended in a short time. At this time, I may still be able to win in the end, but at that time, I am afraid that it will be very different from my own vision.

In the valley, the soldiers of the Tang Army relied on their mountain shields, coupled with their own armor, basically resisted the attack of the Yan army.

"If we continue like this, we will inevitably be trapped here. It's nothing if we die in battle, I'm afraid that time will drag on for a long time, and there will be a loss on the side of Changshan Pass, which will lead to the collapse of the war! Seeing that the soldiers around him fell from time to time, the general who led the troops sank more and more in his heart and said to the people beside him.

"While we still have a chance, we should remind Changshanguan and Guangchang County to let them know that we are attacked, so we should prepare early!" The general next to him replied.

"Okay, light the cigarette immediately, and let the news of our attack go to all directions!" The deputy general nodded and immediately ordered.

"Yes!" The others answered, and immediately began to get busy.

It didn't take long for a yellow pillar of smoke to rise from the valley. The color of this pillar of smoke is relatively special, and it is particularly eye-catching in this green mountain, and it can be seen from a long distance as if it is straight up to the clouds.

This is the latest kind of letter cigarette used by the Tang Army, which took many years of time for the ordnance industry department to develop. Unless the conditions are extremely harsh, this kind of thing is much faster than the Messenger.

The inspiration for the letter smoke comes from the wolf smoke, but there are several colors, each with a different meaning. If it's red, it means it's urgent.

And this yellow color is a warning, indicating that you have encountered an attack, alerting the surrounding allies to pay attention, and it is also a meaning of asking for help.

Because he had never used this kind of thing in a war before, Yan Jun couldn't help but be a little stunned when he saw it at this time.
