There is no doubt that Yan Guo and Dai Guo are already in alliance and stand together. Li Xin was not surprised by this, after all, just as he chose to attack from afar and close to deal with the enemy, the rulers of Yan State and Dai State naturally understood this truth. It's just that it looks like they're acting on their own first.

"Let's go back to the palace first!" After a deep groan, Li Xin commanded.

Soon, the group galloped towards Chang'an City. At the same time, Li Xin first sent someone to summon Wang Meng and Tian He and others to the study, ready to discuss the matter.

"Excuse me! It's important to get down to business, let's get down to business first! Walking into the study, seeing Wang Meng and others about to salute, Li Xin waved his hand and said as he walked.

After sitting down behind the table, he asked Tu Qi to introduce the situation to a few people.

"Let's talk about it! How to solve this matter is better! After the introduction, Li Xin glanced at everyone and asked.

"Since the Yan Dynasty has formed an alliance to attack us, then we have nothing to hesitate about. General Zhenbei and General Zhendong should be ordered to raise their guard immediately, and at the same time, troops should be dispatched north to reinforce Shuofang and Shanggu and other places! The military department Shang Shu Tian He immediately proposed.

He was born in the military, so his views on war have always been relatively tough.

"Having said that, we had been fighting for more than half a year when we were last year, and we had not been stable for almost a year since we put down rebellions in various places. If you raise a large army now, I am afraid that it will affect the stability of the people's livelihood in the territory, especially when it is the summer harvest, it is better to be cautious. It would be a good thing if the soldiers and horses of the country could be withdrawn through negotiations! Xue Zhan, the secretary of the Ministry of Rites, shook his head and said lightly.

If you think about it from the perspective of common sense, he is actually quite right. After all, years of war are not a good thing for a country. Don't talk about it, just talking about Ran Min not long ago is an example.

Ran Min himself is a fierce general, and at the same time, his soldiers and horses are also very powerful. But after he established Ran Wei, he has always been in a state of non-stop war, and there is no construction of people's livelihood at all.

As a result, he was eventually able to travel and eat everywhere, and the army and the people were never able to grow. Otherwise, he would not have been captured and killed by Yan Guo in the end. The people are the foundation of the country, and agriculture is the foundation of the country, and this sentence is not wrong at all in the entire feudal dynasty era.

"Since Dai Guo is determined to form an alliance with Yan Guo and use so many troops to go south, he must have already made up his mind. Even if we want to negotiate, I'm afraid it won't be easy. If it is really negotiated after paying a great price, it is better not to talk about it! Wang Meng said in a deep voice.

"Not bad! Rather than letting the enemy come in and disturb the people's livelihood in the country, it is better for us to keep the enemy out of the country. If we keep them out of the country, as long as the war goes smoothly, the impact on us will not be particularly great. The key is not to drag this war on, otherwise, it will be really troublesome under the protracted time! Xu Fuzi, the head of the household department, also agreed.

"The minister's meaning is also that the war should be resolved quickly, and it is better to settle the war as soon as possible. Otherwise, I'm afraid the enemy will fight more and more! Liang Ping interjected at this time, which basically meant to agree.

At this point, the whole thing is basically settled, after all, most of the important ministers are in favor of going to war. And Li Xin himself basically agrees with this view. All along, he has adhered to an active defensive strategy, that is, trying to replace defense with offense.

And so it was agreed! Immediately ordered Li Erhei and Liao Chuan to defend the enemy on the spot, and at the same time, let Liu Xiaohai raise their vigilance in Shangdang and Leping to strictly prevent the Yan army from attacking. In addition, in this war, the king will lead the army and the flying dragon to the north to support, and the affairs of the court will be handed over to you! Li Xin ordered.

"Yes, the ministers obey!" Wang Meng and the others hurriedly responded.

It has been seven years since the establishment of the Wyvern Rider and the Unbroken Army. In the past seven years, except for the fact that Deng Qiang had rushed to Henan County with three thousand flying dragon horses to fight, he was basically in heavy training.

This time, Li Xin is going to check the results of their training. And the reason why he no longer chose to hide it to the end and began to slowly push these two pro-armies onto the battlefield is because in this situation, the biggest enemy to face may be Yan Guo.

Therefore, before the big war against Yan, first pull these two pro-armies out for actual combat, which can be regarded as a warm-up action.

After several years of training and selection, the number of the two pro-army groups has expanded to 10,000. For Li Xin, this time he didn't have to bring them all with him, as long as he brought half of them.

The 5,000 Flying Dragoons were led by Hong Yi, and the 5,000 Unbroken Army was led by Zhang Hao and Deng Qiang, plus the 20,000 troops mobilized from all over the surrounding areas, adding up to 30,000 troops heading north to support Li Erhei and them.

Li Xin rushed to the camp of the Bupo Army the day after the discussion, and he would lead the Bupo Army to set off first. The troops mobilized from all over the country will depart directly from the garrison, and eventually the 30,000-strong army will be gathered in the territory of Shangjun Fushi County.

And Fushi County is not too far from the Yellow River in the north, Li Erhei and their station, and they can go all the way to that side by going north along the Qin Straight Road. From mid-April, by April 23, 30,000 troops had arrived in the county seat of Fushi.

Li Xin stopped here for a while, mainly to inform the generals of the latest situation and discuss further actions.

"According to the latest information, the 50,000 troops under the command of Tuoba Gu and Tuoba Yujun of Daiguo first crossed the old county of Guling, and then marched west from the north of Shimen Barrier. Now, it has arrived at the western foot of Wula Mountain, and is stationed in the south of Hemu County, north of Xi'an County, and thirty miles east of the confluence of the two tributaries of the north and south of the Great River. The 100,000 army led by Shi Yiqian has also gone south to the north bank of the Great River, with 30,000 troops on the right wing defending our army along the Baiqu River, and 20,000 troops on the left wing defending Yanmen along the mountains. The remaining 50,000 troops are holding on to the north bank of the Great River! Tu Qi introduced the latest news to everyone.

Judging from this news, the forces of Daiguo can be regarded as entering a combat position.

Since ancient times, the Yinshan Mountains have been one of the important dividing lines between the northern nomads and the agricultural civilization of the Central Plains, but the name Yinshan is actually a general term in a broad sense. The entire Yinshan Mountain Range is actually divided into several sections, each with its own name.

Its westernmost section is located in the north of Ningxia, northwest of the first big bend of the Yellow River, and the section northwest of Shuofang County is called Wolf Mountain.

A little further east, the section located north of the northern branch of the Yellow River and west of the old Guling County in the northwest of Wuyuan County is called Serten Mountain. In the south of Serten Mountain, from the east bank of the confluence of the north and south branches of the Yellow River, until the later Baotou as the boundary, this section is called Wula Mountain.

If you go further east, the section east of Baotou to the northeast mountainous area of Shengle City is called Daqingshan. Together, these four sections are a complete Yinshan Mountain Range.

In the past, the Yinshan Mountains were also an important front line of the Central Plains Dynasty's defense of the Saibei Hu people, especially before the Qin and Han dynasties defeated the Xiongnu.

Of course, later Qin Shi Huang and Emperor Wu of the Han Dynasty moved the Great Wall a long distance to the north, so that the northern border of the Central Plains Dynasty was far beyond the Yinshan line.

Among them, whether it is Wolf Mountain in the west, or Wula Mountain and Daqing Mountain in the east, there are roads that can be climbed in the middle. On these roads, there are special pass fortresses, such as Shimen Barrier, which is a fortress located in the northern mountains of Baotou in later generations.

Guling County is located between Serten Mountain and Wula Mountain, because the two mountains are sandwiched here, so it forms a passage of more than 200 miles from east to west. From here, you can go all the way west from the grassland desert outside the Saiwai to the bank of the Yellow River.

Of course, they can also climb directly from the stone gate barrier and other fortresses, but the problem is that these fortresses are basically under the control of the Tang Army now. Except for those close to Shengle.

Tuoba Gu was appointed by Shi Yiqian as a northern lord, and he was originally stationed in Tuoba Xianbei's hometown in Saibei. But this time, in order to attack the Tang Dynasty, he was specially summoned from the grassland.

And if he wants to go south, it is naturally more convenient to go west. Moreover, from the strategic point of view of Shiyiqian, this is also more suitable for outflanking the Shuofang Tang Army.

In terms of troops, Shiyiqian has the most soldiers and horses on this road, and among the 30,000 Tang troops in the entire Shuofang, more than 20,000 people are basically contained in this area. Sun Tie was left with more than 5,000 people, stationed in the west and south of Xi'an County, to prevent Tuoba from leading the army to cross the river and advance westward.

If it weren't for the Yellow River blocking it, I'm afraid that the Shiyiqian army would have gone directly south to Shangjun by now.

"What's going on over there in Yan Kingdom? Murong Wen's people all the way, where have they been now, but they have found their traces? Li Xin listened and asked.

"For the time being, the Yan army east of Taihang Mountain has not made any major movements. As for Murong Wen's soldiers and horses, there has been no trace of him since he left Pingzhou to Saiwai. Because that side is our weak zone, and the territory is vast, it is really difficult to find the whereabouts of the other party! Tu Qi replied.

"No matter how many people are sent, we must find the whereabouts of Murong Wen's soldiers and horses as soon as possible. In this case, Liao Chuan's side should take precautions first. On the Yan side, it is presumably necessary to wait until our side has a war before launching an action. Otherwise, in the case of not being sure whether Shi Yiqian will really send troops as promised, they will inevitably be more cautious! Hearing this answer, Li Xin couldn't help frowning, and then said.
