Today's court exploded again, this is the second time this month, the last time was after the court found that Kelie fled quietly, Emperor Yan Shu personally questioned the relevant personnel in this Taijing Palace, and as a result, he cut off the heads of five people, including Yanjing Yicheng, Nancheng Patrol Battalion Captain, Wailang of the Left of the Ministry of Rites, Nancheng Water Division Yamen Governor and Yanjing Town Fu Division Right Guard Deputy Qianzong.

Originally, there was such a big mistake, and it was inevitable to ask for the crime and go to prison to cut off the head, but the identities of these five people were very sensitive, because they were all henchmen of the Jinran family, although they all belonged to the small role of "not entering the stream" in the Jinran family, but everyone with a discerning eye knew that this was Emperor Yanshu taking the opportunity to move the knife to Jinran.

And last time, Jin Ran, who was the main character, was the old god standing aside with his eyes closed, without saying a word or saying a word throughout the whole process, and Emperor Yan Jin, who was so angry that his face was blue throughout the whole process, and he had a feeling that a dog biting a turtle and not being able to swallow.

And this time, the reason was that the fine work sent by the Yan State to Hu Meng sent back the news that Kelie officially inherited the throne, although the change of the country's supreme power was a major event, but it was also a normal thing, but the Great Yan Imperial Court was now in a state of change of color, not afraid of this person, but worried about the trouble he would bring.

After all, Dayan has been blacklisted, which is an indisputable fact.

So today's court meeting is around this theme, as for the content of the discussion, is how to do a good job in the defense of the border fortress, because what can be done now is only for the soldiers to block the water and cover the earth, but there is no way to catch it anymore, Dayan is about to face the Humeng iron cavalry rolling south!

There are four prefectures bordering Yanguo and Humeng, namely Dingzhou in the northwest, Caizhou in the north, and Yanzhou and Yunzhou in the northeast.

Dingzhou in the northwest is a place of four wars, and it is easy to attack and difficult to defend, the west is Molan, the north is Humeng, the military expenditure of the Dayan court in Dingzhou every year is twice that of other states, on the one hand, because Dingzhou belongs to the Northwest Army, which is the only sixth army that is still in the hands of the royal family, and the court intends to support its own family.

On the other hand, it is the embarrassing but very important military position of Dingzhou, if there is no Dingzhou as a buffer, then Hu Meng's iron cavalry will go straight to the food pass, and if the food pass is lost, then Yanjing can no longer be safeguarded, to use a cheesy metaphor, at this time Yan Guo is a girl without clothes in the eyes of the Humeng people, and others want to go on it.

Therefore, the importance of Dingzhou is self-evident, the imperial court spent huge manpower and financial resources in Dingzhou, and placed two core military fortresses in Jinjin Town and Xiema Town, Jinzhen is located in the northwest of Dingzhou, 100 miles away from the border of Molan, Xiema Town is located in the north of Dingzhou, 200 miles away from the border of Yanmeng, the two towns are horns of each other, support each other, like the two tiger teeth placed in Dingzhou, deterring Molan and Humeng.

Dingzhou Prefecture is located in the central Liangzhou, but also the transportation hub of the whole Dingzhou, to the north can reach gold, Xiema, to the south to the Guan, Shuzhou, Dingzhou all the material turnover has to pass here, because of its special geographical location, its city wall system has far exceeded the scale of the city wall of the internal state of Yan, the reason for this is to be in Xiema and the two towns of gold were captured, the Yan army in Dingzhou can still have room for maneuver.

It can be said that the two towns of Gold and Xiema are the teeth of this Dingzhou, and Liangzhou is the heart of this Dingzhou.

There are five major counties after Liangzhou, namely Xiping, Xing'an, Dingshui, Dingping, Yunzhong, Xiping is located between Liangzhou and Jinjinzhen, Dingshui is located in the southernmost part of Dingzhou, and it is Anxi County of Shuzhou separated by a river, Dingping and Yunzhong are located outside the Yaguan, and the Caiguan are separated by a river, if the war in Dingzhou is unfavorable, these two county towns are the first stop of the Yanguo support force to go out of the west of the Caiguan.

As for Hung Yen, it is located under the Hidden Clouds and Snow Region, and does not have much strategic positioning.

After talking about Dingzhou, let's talk about Caizhou, Caizhou is located in the north of the territory of Yanguo, and it is also the defense area of the Northwest Army.

There are two major passes in Caizhou, one is the Caiguan across the river from Dingzhou, and the other is the Hanyue Pass that looks directly at Humeng.

Although it is not on the border, the number of permanent garrison troops is as high as 20,000, and its importance is self-evident.

As for the Hanyue Pass, it is a pass that has been built by the Zhao State in the Spring and Autumn Period, and its role is also used to defend against the Humeng in the north, you must know that the advantage of the Humeng army is that they come and go like the wind Humeng iron horse, and the territory of Caizhou is a horse Pingchuan, just to maximize the Humeng people to give full play to their advantages, all the Zhao people at that time built this huge military pass by the river, to prevent the Humeng people's unscrupulous iron hooves, but in the end they made a wedding dress for the Yan State.

The flow of the Zimu River from south to north turns east outside the Hanyue Pass, and the city wall of the Hanyue Pass is only a hundred zhang away from the Zimu River, which is just the farthest distance that the Dayan strong crossbow can reach, if it is in the wet season, this distance can be reduced to ten zhang.

Not to mention that Humeng did not have the shipbuilding technology of large warships, such a narrow buffer distance could not give the Humeng army any time to reorganize and assemble after crossing the river, and there were many silt and soft beaches by the river, and Humeng's war horses could not play a role here at all.

In this way, Hu Meng's army could only look at the tall walls of Hanyue Pass from a distance across the river.

The only disadvantage of Hanyue Pass is precisely the natural danger Zimu River on which it depends, because Hanyue Pass is located in the north, so every winter, the climate here is extremely cold, resulting in the formation of ice up to three feet thick on the surface of the Zimu River, at this time, the Zimu River, except for the surface will be slippery, there is no difference from ordinary land.

For Hu Meng, this is the best time to attack Hanyue Pass, because the Hu Meng people have been crawling in the cold climate since they were children, so there is no difference in winter combat except for wearing thicker, and this is precisely the fatal shortcoming of the Yan soldiers.

Therefore, in response to this situation, Yan Guo deliberately organized a Yanyun army with a scale of 20,000 people, all of whom were recruited from the two states of Yanyun in the northeast, and had only one duty from the beginning of their enlistment, that is, to guard Hanyue Pass, no matter whether there was a war here, they never moved their nests, until they died in battle or returned to their hometowns.

In addition, there are two states of Yanyun, but because they are separated from Humeng by the Evergreen Mountains, the probability of being directly attacked by Humeng is almost zero.

The Evergreen Mountains are a primeval woodland with high mountains and deep forests, and even hunters who have been crawling in the mountains since childhood do not dare to enter the depths of the mountains, and if they want to cross the entire mountain range, it is even more of a thing that can only be thought about.

But after the unification of the whole country, in order to be on the safe side, or on the border between Yanzhou and Jizhou, a pass called Yanyun Pass was built, although Yanyun Pass did not have the majesty of Yanyue Pass and Hanyue Pass, but it was far better than other passes.

At that time, when this pass was built, many people felt that it was a useless building that wasted financial resources and manpower, but under the strong request of Emperor Zhaolie, the household department still had to obediently allocate money and grain to complete its construction.

Didn't Emperor Zhaolie know that Yanyun Pass was just a waste of money and food? In fact, he also knows that he can just do this to have peace of mind.

Judging from the characteristics of Humeng's southward movement over the years, if they choose to invade the border in the autumn, they will generally only go to Xiema Town to enter Dingzhou, take advantage of Humeng's iron cavalry to attack those small villages and villages, grab some money, grain, livestock, and sometimes women, but they will not commit any offense against the big cities in the autumn, and then evacuate in a very short time.

This is commonly known as the "autumn wind" in the population of Yan State, although it will bring a certain amount of chaos and loss of people and property to the state, but on the whole, it does not damage the muscles and bones, so the imperial court has always turned a blind eye to the autumn wind, and if it can be prevented, it will be prevented.

If the Humeng people choose to invade the border in winter, and they are still preparing to attack the Kouhan Yueguan from the frozen Zimu River, then they are not just trying to grab some finances, but really want to invade the hinterland of the Central Plains, and even have the intention of destroying other countries.

And this situation only appeared twice after the establishment of the Yan State, the first time was the year when Emperor Yan Jing first ascended the throne, the first year of Jingyu, Hu Meng wanted to take advantage of the first death of the Emperor of Yan State, when the foundation of the new emperor was not stable, he sent 300,000 troops to the south in two ways, one way to take advantage of the frozen river surface of the Zimu River to storm Hanyue Pass, and the other way into Dingzhou, the Yan army in Dingzhou killed a person on his back, and then approached the city of Yuguan.

It was the first time that the Yan State faced the situation of possible annihilation, but fortunately, because of the death battle of the Yan soldiers, they held the Yaguan Pass and the Hanyue Pass, until the beginning of the spring of the following year, the ice of the Zimu River began to melt, and Hu Meng, who had not been able to attack for a long time, had to retreat.

It was also in this battle that Emperor Yan Jing saw the strength of Hu Meng and the hidden dangers behind Yan Guo, and took defeating Hu Meng as his ultimate goal in this life, and then he also successfully achieved his goal.

The second time was when Emperor Yan Hui, the Yan Kingdom that had just pacified the Yan Youchu Rebellion was devastated, and Hu Meng also took this opportunity to cross the Broken Heaven Trench, captured the Heluo Grassland, and then took advantage of the victory to wave the army to the Han Yue Pass, when the defenders of the Han Yue Pass had been exhausted in the civil war, it was the 20,000 Yan Yun troops who never moved their nests to guard the last gate of the Yan Kingdom with their flesh and blood.

Now it seems that the scene of the year is about to happen again, so the civil and military forces of the Manchu Dynasty are debating how to defend against the impending crisis.

Some people think that attack is the best defense, so instead of sitting back and waiting here, it is better to organize the army to strike first and take the initiative to attack Humeng.

Of course, this point of view is agreed by a small number of people, but the vast majority of people do not agree, the reason is very simple, offense consumes much more manpower and material resources than defense, and fighting a war is actually fighting resources, and material collection and transportation are the first and most troublesome problems.

Take the initiative to attack Humeng, in the vast grassland, the cavalry of Yan State is definitely not the opponent of Humeng Iron Cavalry, if you go deep into the territory of Humeng, the material supply can not keep up at all, everything can only learn from Humeng people to fight and feed the war, and make a living by plundering, but since Yan lost the Heluo grassland, the quality of the war horse is far inferior to Humeng, you must know that the war horses ridden by Yanyun Iron Cavalry, when Emperor Jing defeated Humeng Iron Cavalry, are all products of Heluo Grassland.

Running as fast as others, and hitting and beating, what's the difference between this and sending to death?

Moreover, the national strength of Yan has just improved a little, and the wounds left by the war in the hearts of the people have just healed, thinking that they will finally be able to live in peace in the future.
