The action of the Jin army outside Yanmen Pass to reduce its troops and the small force of Jin army that appeared in Xinzhou alerted the Hedong Marshal's Mansion.

The vast majority of the Northern Expeditionary Army had never been stationed in the north, let alone experienced the cold winter in the north, and it was difficult for them to adapt to the severe cold.

As the weather became colder and colder, even the basic daily drills had been interrupted, and in this case, even if the Yanmen Pass could be held, the Jin army might cross the mountains or enter Hedong in batches from other trails.

The Jin army gathered a small number of people, and took advantage of the fact that the Northern Expeditionary Army was unable to move to support in winter, killing people and setting fires, and wreaking havoc, and Hedong would face unprecedented chaos and disaster.

If Hedong is unstable, it is delusional for the Northern Expeditionary Army to want to go out of the pass and take Yunzhong, let alone to the east to suppress Zhendingfu and Yanjing.

Now the Jin army that infiltrated Xinzhou has difficulty in supplying grain and grass, and can only rely on looting, all of them are limited, not more than 1,000 people, but if they draw troops from Yanmen Pass, and then use other places to enter Xinzhou, the trouble will be big, except for a few big cities, other small cities and small counties will fall back into the hands of the Jin people.

Xin Qiji discussed the situation in Hedong with Xue Wang, who returned to Taiyuan Mansion from the north, and believed that the place that was most likely to be broken through by the Jin people taking advantage of the heavy snow to close the mountain was Lingqiu.

Xin Qiji believed that if the Jin army borrowed Dao Lingqiu from Guangling, and then moved west to Hedong, avoiding the Northern Expeditionary Army and guarding Yanmen Pass, then their chances of success would be very high.

With the current situation in Hedong, a small force of Jin troops can still deal with it, if more than 10,000 people enter Hedong, Xinzhou and Taiyuan will be in chaos, so it is very important to cut off the idea of Jin people entering Xinzhou from the east of Xinzhou, as long as they survive this cold winter and wait until the warm spring comes, the Northern Expeditionary Army is not afraid of any Jin army.

Before coming to Hedong, Yang Congyi gave Xin Qiji a map of Hedong and Guanwai, and most of Hedong's spy reports on the Jin State were also in his hands, so Xin Qiji's judgment of the situation and the enemy's situation was clearer and more accurate than Xue Wang's as the deputy marshal.

Xue Wang has been in the army for many years, and he still understands some of the circumstances, no matter how the Great Song Dynasty court changes, no matter how much power is given to the generals, it will never relax all the control over the generals, at least the military supplies and grass, logistics supplies and local government affairs are still basically in the hands of Wenchen.

Even when Yang Congyi was in full swing, the military and political power was monopolized, and it was generally less than half a month, and he would soon hand over the power of government affairs and logistics supply to the civil servants and civil officials to supervise, and the military generals could only have the opportunity to lead the army to fight if they obeyed the rules, otherwise they would lose more than just power.

Xue Wang has followed Yang Congyi for more than 20 years, and he understands these truths.

Regarding the young deputy marshal Xin Qiji, Xue Wang rarely objected to his suggestion, because he knew that Xin Qiji came to Hedong by the order of Yang Congyi and the imperial court, and Xin Qiji himself was not a hairy boy or an incompetent person.

The entire strategy of capturing Taiyuan, Xinzhou, and Pingyang Mansion was planned by Xin Qiji and him at that time, and at that time, Xue Wang had already seen that Xin Qiji had the talent to fight, as well as a smart mind, and even more enthusiastic and ambition to restore Yanyun in the north.

Since Yang Congyi and the imperial court gave Xin Qiji a chance, Xue Wang naturally would not object.

At least judging from the current results in Hedong, Yang Congyi and the imperial court saw Xin Qiji's right view, and he did have extraordinary ability to govern the army, command the army, and plan.

Xin Qiji quickly persuaded Xue Wang to send 3,000 elites from the east of Xinzhou into the mountains and attack Lingqiu.

Half a month later, the Northern Expeditionary Army that attacked Lingqiu sent back the news that they climbed over the mountains through the path and suddenly appeared near Lingqiu City.

When the news came back, Taiyuan Prefecture immediately sent 3,000 troops again, carrying a large number of grain and grass materials, and entered Lingqiu County through Xinzhou, Yanmen County, and Fanzhi County to the east.

At the same time as the army, they entered Lingqiu eastward, as well as several officials personally selected by Xin Qiji.

In the opinion of the Commander-in-Chief of the Northern Expeditionary Army, since it is possible for the Jin people to attack the east of the Guannei River through Lingqiu, why can't the Northern Expeditionary Army use Lingqiu as a springboard to attack Yunzhong outside the Guan?

If the time comes, the Northern Expeditionary Army will divide into two routes, attacking Yunzhong from Yanmen and Lingqiu to the east and west at the same time, and the chances of capturing Yunzhong will increase a lot, so it is very important to send people to manage Lingqiu.

Guangling to Lingqiu is separated by high mountains, usually no snow and no rain, it takes three or four days to go a trip, and now the heavy snow covers the mountain, it is more difficult to come and go, let alone pass the army.

Therefore, after the successful sneak attack on Lingqiu with the assistance of the Northern Expeditionary Army, the Guangling Jin Army stationed in Guangling did not react for a short time, and only a small number of spies appeared near Lingqiu.

The Northern Expeditionary Army, which has winter clothes, has been stationed on the section of the road between Guangling and Lingqiu, plus 5,000 people stationed in Lingqiu City, if the Jin army wants to recapture Lingqiu, it can only wait until the ice and snow melt, that is to say, it will have to wait until the spring is warm next year, around March.

The Song army of Yanmen Pass was practicing every day, and it was in full swing, and the Jin army outside the gate was still waiting for colder weather.

The Jin army lives in the cold north all the year round, and the soldiers naturally have to take advantage of the cold-tolerant advantage, if everything is really as expected, then the Yanmen Pass, which is usually difficult to capture, will be easily taken down with the arrival of the harsh winter.

However, the commander of the Jin army did not know what was happening at the Yanmen Gate, insisting that the Song army was bluffing for an hour and a half at a time, but did not know that the Song army officers and men were practicing and adapting to marching and fighting in thick winter clothes.

So more than a month later, on the twenty-third day of the eighth year of Beiding, in a snowstorm with a cold wind howling, the Jin army outside the Guanwai suddenly attacked Yanmen.

After a month of training in the cold wind, the Song army, which had greatly increased its confidence, was naturally not afraid, and immediately led troops out of the pass, and launched a fierce battle with the Jin army two miles before the pass.

The two armies did not fight for two months, and when they fought again, the momentum of both sides was high, and they directly attacked the opponent's camp in the wind and snow, and there was a great tendency to move forward, and for a time blood flew around with white snowflakes.

Song Jun was dressed in cotton clothes, cotton pants and cotton shoes, with cotton towels covering his mouth, nose and neck, and gloves sewn from fur and cotton on his hands.

And Jin Jun had nothing else to keep out the cold except the leather jacket on his body and the hat on his head.

Fighting a war is not only by relying on the legs and standing firmly, but also by relying on the hands to grasp the swords, guns and weapons.

Compared with the two, the Jin army is obviously at a disadvantage.

On the battlefield, this is exactly the case.

At the beginning, with their enthusiasm, the Song and Jin armies could still fight equally.

After two quarters of an hour, the hands of the Jin soldiers began to stiffen, and they did not obey the call.

The officers and men of the Song army felt that they were in full swing, and the more they fought, the warmer they became, and the more they fought, the smoother they became.

An hour later, the commander of the Jin army, who was in the rear, finally found that the battle situation was not as he expected before the battle, and when he sent someone to find out that the Song army was dressed differently, he was shocked that he might have made a mistake in judgment, so he hurriedly ordered a retreat.

At this time, nearly an hour had passed.

The Jin army retreated, and Yuan Hua immediately ordered to collect the troops, clean up the battlefield, and bring back the dead and wounded soldiers of the Great Song Dynasty, without choosing to pursue rashly.

In this battle, the two sides only fought for more than two hours, and the Song army achieved a lot of results, killing nearly 5,000 enemies and suffering more than 600 casualties, which was a great victory.

In fact, the Song army could have defended the city, but there were not many bows and arrows in reserve, the heavy snow closed the mountain, and it was difficult for Taiyuan Mansion to transport supplies, so they had to save it for the next sneak attack of the enemy.

Of course, there is another reason, that is, Yuan Hua wants the soldiers to restore and enhance their confidence through a hearty victory.

Judging from the results, with the winter clothes sent by Jinan Mansion thousands of miles away and more than a month of adaptation exercises, Yuan Hua was controlled, and the soldiers of the Yanmen Pass defenders also did it.

Through this face-to-face fierce battle, the morale of the Great Song generals increased greatly, while the Jin army lost its troops and lost its morale to the extreme, not to mention that their confidence and trust in their own commanders were also greatly reduced.

Yanmen Pass, this cold winter is worry-free!

The Yanmen Pass was guarded, and the Jin people could not enter Xinzhou on a large scale, and the Jin people could not recapture Lingqiu, nor could they enter Xinzhou from Guangling through Lingqiu.

These two places were controlled by the Great Song Dynasty, and not only could the Jin people not be able to enter the Guannei from outside the Guan, but their connection with the Jin army of Zhending Mansion was also cut off by Lingqiu.

The Lingqiu between Zhending Mansion and Datong Mansion could have been connected through Guangling, Lingqiu and Laiyuan, but now the Lingqiu between Guangling and Laiyuan is in the hands of the Northern Expeditionary Army of the Great Song Dynasty, Lingqiu was lost, and Zhending Mansion and Datong Mansion soon lost contact.

Before the Jin people recaptured Lingqiu, they could only open another passage to restore the connection between Datong Mansion and Zhending Mansion, but in the harsh winter when the snow closed the mountain, it was impossible to predict how much time it would take.

After the loss of the three prefectures in Hedong, in the winter of the eighth year of Beiding, the Xijin court in Datong Mansion also lost contact with Zhending Mansion.

That is to say, during the confrontation between the Great Song Dynasty, the Western Jin Dynasty, and the Eastern Jin Dynasty in recent years, the situation in Xijin gradually improved, but suddenly began to take a sharp turn from the summer and autumn of the eighth year of Beiding, and when winter came, in just a few months, Xijin lost the land and people of dozens of state capitals in Hedong, Guanzhong, and northern Shaanxi, as well as nearly 200,000 troops.

In the winter of the eighth year of Beiding, the power of the three kingdoms underwent tremendous changes.

The power of Xijin has declined step by step, and except for Zhending Mansion, which has lost contact, there is almost no place to stand in the Central Plains.

Through the Northern Expedition, the Great Song Dynasty recovered Hedong, Guanzhong, and northern Shaanxi, not only did its strength increase greatly, but the morale of the army and the people was also very high.

Although Dongjin and the Great Song Dynasty had a confrontation in Hejian Mansion, there was no direct conflict again, and the strength in Yanjing was faintly recovering.

Now the strength of the Three Kingdoms has begun to appear, the Great Song Dynasty that has regained the old land ranks first, occupying Yanjing, Liaoyang, Shangjing and other places in Dongjin, after losing Hedong, Guanzhong, and northern Shaanxi in Xijin, it is a trend of coming from behind, when it is second, Xijin has lost land one after another, although there are still Datong Mansion, Zhending Mansion, Linhuang Mansion, Dading Mansion and the Mongolian Departments of the Grassland, but the military spirit is greatly lost, morale is greatly damaged, and it can only rank third.

In this winter, when dozens of state capitals in Hedong and Guanzhong were lost, a major event occurred in Xijin Datong Mansion.

Emperor Wan Yanliang lost too much city land, and his anger could not be extinguished, and he finally suffered a stroke, and died a few days later.

This Wan Yan Liang, who ascended the throne by killing the king, moved the capital three times, gathered millions of troops to invade the Great Song Dynasty in the south, and was the emperor of the Jin State for twenty-four years, died, and he destroyed the Jin Kingdom and himself because of his obsession.

On the day of Wan Yan Liang's death, the twenty-three-year-old crown prince Wan Yan Guangying ascended the throne in Datong Mansion and succeeded to the throne of Xijin.
