However, no matter when Murong Ke planned to act, for Li Xin, it was already time to do it. "By the way, the matter of our reinforcements going north, Dai Guo and Yan Guo should know about it now, right?" After thinking for a while, Li Xin suddenly asked.

"Judging from the current situation, Shi Yiqian and Yan Guo already know that we are sending troops north. Moreover, we also probably know the number of our troops, and even more so that it is led by His Highness himself. ”

"Well, in that case, they should have roughly figured out where we're by now!" Li Xin nodded and said thoughtfully.

"Your Highness, what should we do next, please make it clear!"

"Tu Qi, you must closely monitor the movements of the enemy forces on the front line of Shangdang and Shanggu, and once there is any movement in the Yan Kingdom, you must immediately report to this king!" After pondering for a while, Li Xin made a decision and said to Tu Qi first.

"Your Highness rest assured, the minister will go to handle this matter immediately!"

"In addition, our 30,000 troops are here, Deng Qiang, you stay and lead the army to continue north, don't be too anxious, don't be too slow, everything can be done at a normal speed! This king personally led the flying dragon cavalry and the unbroken army to take the lead, and it would be better to kill one of them by surprise! Afterwards, Li Xin ordered the generals present.

"The last general commands!" The generals hurriedly bowed in response.

"In this battle, our main target is not Yan Guo, but Dai Guo. Since they came to the door on their own initiative, then we have to fight a good fight. The best thing is to be able to send Daiguo back to his hometown north of Yinshan in World War I! Li Xin stood up and said slowly.

After the discussion was made, the army began to set out again. But that night, Li Xin and Deng Qiang were divided into two roads, Li Xin personally led the army to the north to raid, the flying dragon cavalry and the unbroken army all rode forward, and they were killed from Fushi County to the south bank of the Yellow River in one day and one night.

There, Li Xin did not stop to greet Li Erhei, but directly led the army to quietly cross the Yellow River from Heyin County in Wuyuan County and entered the territory of Wuyuan County.

After that, he sent someone to see Li Erhei, and the general order was delivered to him. At the same time, the army on the west bank of Baiqushui was ordered to make some adjustments.

There were not many Tang troops on the west bank of Baiqushui, only more than 8,000 people in total. But because they relied on the benefits of the Baiqu water and the support of the main force on the south bank, they were stunned to block the more than 30,000 generations of troops on the east bank of the river.

Of course, such a thing cannot go on forever. After all, once Shi Yiqian was determined to launch a general offensive, the main force of the Tang Army on the south bank would inevitably no longer be able to cope with this. But Li Xin's arrival has changed this situation.

This time, a total of 150,000 troops went out on behalf of the country, which can be regarded as the strength of the whole country to march south. After Li Xin goes north, the number of troops in Shuofang will eventually reach about 60,000.

Although it is said that it is less than half of the Dai army, for Li Xin, as long as he arranges it properly, there is no problem in defeating the enemy army.

The Dai soldiers acted in two ways, and when Li Xin arrived at Wuyuan County, the 50,000 troops on the west Tuoba Gu Road had already fought with Sun Tie twice.

And the reason why this happened was because after hearing the news of Li Xin's northward journey, Tuoba Gu planned to take the first step and cross the Yellow River before the Tang army reinforcements arrived.

Otherwise, if the reinforcements of the Tang Army arrive, it may not be so easy for them to cross the river again. And it was precisely because Sun Tie saw through this that he blocked the west and south sides of the Yellow River, and resolutely did not let the other party cross the river first.

Li Xin's priority is to solve Tuoba Gu's soldiers. First, because there are fewer soldiers and horses on this road, and secondly, because after this place is resolved, he can concentrate all his forces to deal with the soldiers and horses of Shiyigan.

There is no doubt that Shi Yiqian still did not attack after hearing the news of his heading north, apparently waiting for his arrival. The purpose of this is not just to fight to the death with the Tang army, but to attract the attention of the Tang Dynasty to his side.

After all, where Li Xin is, the eyes of the entire Datang are basically there. In other words, Shi Yiqian is fulfilling his duties as an ally, containing the Tang army for Yan Guo and creating opportunities for Murong Ke's side.

Li Xin just figured this out, so he couldn't let Shi Yiqian succeed. He had to disintegrate part of the power of the Dai Guo before the Yan Kingdom was launched, so as to deal with the severe situation that might be encountered later.

Therefore, his order to Li Erhei was to transfer some of the soldiers and horses on the south bank to the west of Baiqushui, so that the troops along Baiqushui would reach about 15,000. As for the defense of the south bank, it was taken over by the 20,000 troops who arrived later.

Li Xin's purpose was to keep Shi Yiqian firmly on the north bank of the Yellow River, so that he could not disturb his war in the west. It's as if Shi Yiqian wants to contain himself, and he also wants to contain him at this time, which can be regarded as mutual use!

After arranging the matter on Li Erhei's side, Li Xin began to take the next step.

He first sent Zhang Hao to lead 5,000 Bupo troops to march west along the north bank of the Yellow River and rush to the place where Sun Tie was to support him. As for himself, he led five thousand flying dragons to ride north, and after crossing the stone barrier, he made a detour to the back of Tuoba Gu's army.

It's the easiest and most effective way to do it, and it's tried and tested. As long as you can kill behind the enemy, and kill them in one fell swoop while the other party is not noticing, you will definitely be able to achieve a big victory.

The stone barrier is an important defensive place in the entire Shuofang land, and the so-called barrier is actually the meaning of the barrier. This kind of thing is not a pass, let alone a castle, it should be said to be a kind of beacon built up by using the terrain of the mountain.

Although they may not be large in size, they play an important role in border defense and warfare because of their dangerous location. Especially like some of the larger ones, there will be a relatively large number of troops stationed.

Among them, the stone gate barrier near Wuyuan County is one of the most important. This is not just a barrier, but also the military center of Wuyuan County in the Western Han Dynasty.

Because it is located in the valley where the stone gate water flows from north to south, and this stone gate barrier is like two stone gates that lock the road, hence the name. From here, you can directly climb over the Ula Mountains and enter the passage between the Ula Mountains and the Serten Mountains.

During the two Han Dynasty, the Han Dynasty army that attacked the Xiongnu in the north every time often crossed the Wula Mountain, and then went on an expedition to the Xiongnu Hu people in the north. Now that this place is in the hands of the Tang Army, Li Xin has no reason not to use it.

If you follow the southern foot of the Ula Mountain all the way west to the front of the Dai army, the distance of this road is very long. And when you climb over the stone barrier, the distance will be greatly shortened.

However, the enemy also knew that this fortress was in the hands of the Don army. Therefore, it is very likely that Tuoba Gu and they will prevent the Tang army from sending troops from here in advance.

The most likely design is probably to send some soldiers and horses to hide in the valley north of the stone barrier, waiting for the Tang army to pass by and ambush them.

Despite this, Li Xin decided to go this way, mainly because it had a greater success rate in doing so. Of course, it is still necessary to prepare in advance, and it would be a bit stupid to not prepare knowing that there is a possibility of being ambushed.

Therefore, before he acted, he specially sent spies from the Ministry Division and some elite scouts to let them quietly pass through the stone barrier, and then sneak into the mountains and forests on both sides to search.

This method is obviously very effective, because in the dense forests on both sides of the valley more than ten miles away from the stone gate barrier, there are indeed more than 2,000 soldiers hiding in the army. And these people were defeated by the people sent by Li Xin, thus opening the road to Shanbei.

Before Tuoba Gu's side could react, Li Xin led the flying dragon rider to quickly cross the stone barrier, and then killed it in the direction of the camp of the army to the west.

On Sun Tie's side, after receiving the reinforcements brought by Zhang Hao and Li Xin's military order, he immediately took action. This time, he did not adopt a passive defensive strategy, but took the initiative to attack the representative army.

Since the Dai army is basically cavalry, it is more appropriate to provoke and lure rather than take the initiative to attack. Sun Tie sent some cavalry to gallop all the way to the enemy camp, and then there was a flurry of arrows inside.

The substitute troops in the enemy camp were naturally furious, and hurriedly concentrated their troops and horses to prepare to kill the generals. But at this time, the Tang army suddenly fled. Tuoba was also cautious, and when he saw that something was wrong with the situation, he ordered that he should not chase after him.

But who would have thought that after that, the Tang army ran again and again to provoke himself, not only releasing ordinary arrows, but also releasing rockets into the camp. Where can I bear this, the soldiers of the acting army are furious, and Tuoba Gu can't bear it anymore, so he sent some soldiers and horses to chase him out.

This time it happened to fall into Sun Tie's plan, he attracted this part of the army to his front, and then sent the Bupo army led by Zhang Hao to fight. Heavy infantry against these light cavalry was basically no threat.

It was almost easy to get rid of these pursuers, and then, Sun Tie sent someone to provoke again.

And after Tuoba Gu's side found out that two or three groups of people had been sent and never returned, he naturally realized that this was Tang Jun's strategy. But his idea was that these groups of people were wiped out by the Tang Army, and that was because there were too few people, so wouldn't it be okay for me to send more people out?

So, in the end, it was Tuoba Gu who ordered all the troops to attack and kill Sun Tie's side. The war suddenly fell into the previous kind of big war, but this time Sun Tie did not accept it when he saw it, but fought with all his might, dragging the other party into the battlefield.
