When the Liao army successfully completed the conquest of the party and returned to the dynasty, the internal turmoil in the Great Song Dynasty had not completely stopped.

Because the process of the Liao army led by Yelu Mo to conquer the party items was too smooth, so smooth that Yelu Mo could not have imagined it.

Since the process went smoothly, it didn't take too much time to return to the court. And because it didn't take too much time, it was not impossible to take advantage of the fact that the morale of this army was booming, but it was not impossible for the Liao State to move south to continue the stillborn plan of the Song Dynasty at this time.

Coach Yelumo also thought of such a plan, and also suggested it to Han Derang and Xiao Xuan, but sometimes people are not as good as heaven.

At this time, the backyard of the Liao Empire caught fire, because Goryeo, which had originally severed relations with the Central Plains and completely surrendered to the Korean Peninsula of the Liao Empire, suddenly rebelled at this time.

This made the high-level of the Liao Empire a little unexpected, why would this Goryeo rebel.

The relationship between Goryeo and the Liao Empire has long been considered to be good, as early as the time of the Liao Taizu Yelu Abaoji, the Wang Goryeo on the peninsula had sent an envoy to the Liao State, but at that time Goryeo was not subordinate to the Liao State, but to the Central Plains.

Because although the Central Plains was in turmoil at that time, the Liao State had also just been established, and the strength of the Central Plains was still stronger, so although the Wang Goryeo at this time communicated with the Liao State, it did not surrender.

At this time, the Liao State also knew that its own strength was not so strong, so it did not require Goryeo to be subordinate.

Although Taejong had attacked Goryeo, he was unable to conquer it until the second year of the Liao Taizong meeting (939), when the Liao Kingdom and Goryeo suddenly broke off for unknown reasons, and this time lasted for more than 40 years.

In the past 40 years, the Liao State has gradually grown from a small country established by a nomadic clan to a huge empire on the grassland, especially when Shi Jingjiao ceded the support of the Liao State to the Sixteen Prefectures of Yanyun of the Liao State, the Liao Empire gradually entered a period of rapid development.

Of course, during this period, the Central Plains also underwent earth-shaking changes, and the Later Jin, Later Han, and Later Zhou were established one after another, and then perished one after another. A man named Zhao Kuangyin established a dynasty called Song, which quickly destroyed other countries and gradually unified the Central Plains.

After the Song unified the Central Plains, the Liao Empire suddenly realized the need to strengthen relations with Goryeo, which had been cut off for more than forty years.

Because of the unification of the Central Plains by the Great Song Dynasty, the southern part of the Liao Empire was no longer chaotic, and the south became stronger, which brought hidden dangers to the security of the Liao Empire itself.

In order to fight against this hidden danger with all its might, Wang's Goryeo on the peninsula, which was the flank of the Liao Empire, was valued by the Liao Empire, and the Liao Empire realized that in order to be able to fight against the Song Empire in the south without worries.

Its own flanks must be safe, but at this time, the flanked Goryeo is not subordinate to itself, on the contrary, its suzerainty has always been the Central Plains Dynasty, and at this time it is the Song Empire.

For this insecurity, the Liao Empire naturally no longer allowed its existence, so the Liao Empire began to demand that Goryeo sever ties with the Song and belong to itself, and began to use force to threaten Goryeo.

But Goryeo was unmoved and still maintained contact with the Great Song Dynasty.

As a result, the Liao State lost patience and launched an attack on Goryeo in 992. Goryeo did not have the strength to resist the Liao attack, and the Great Song Dynasty was unable to help due to its distance.

So in desperation, Goryeo could only choose to surrender and surrender to the Liao State.

The Liao State also readily accepted Goryeo's surrender and vassals, and in order to show the magnanimity of the Liao Empire, the Liao Empire allocated a large area of land east of the Yalu River to Goryeo.

However, at this time, Goryeo still did not sever its relations with the Song Dynasty, and at this time, Goryeo was subordinate to the two great powers of the Liao and Song dynasties at the same time.

However, diplomatically, the wall-riding faction has not come to a good end, especially since the wall stands between two hostile forces, so Goryeo must choose a country.

In the minds of the Goryeo royal family, they were more willing to submit to the Great Song Dynasty. After all, the Central Plains Dynasty often treats its vassals very well. Thick and thin has always been the characteristic of the Central Plains Dynasty.

In addition, over the years, Zhao Weiji began to sell steel weapons to the peninsula, so that Goryeo's military strength has been improved to a certain extent, and they no longer dare to act like during the Yongxi Northern Expedition, which was taken by the Liao Empire.

Instead, he sent people to the Central Plains, saying that if the Great Song Dynasty invaded Liao, then Goryeo would definitely cooperate in the battle.

At that time, Taizong Zhao Guangyi had not yet died, and his two expeditions to Liao during his reign ended in failure, so the invasion of Liao has always made him angry, and now Goryeo sent an envoy to say that he could cooperate, so that Taizong once had the desire to go on a northern expedition.

However, not long after that, he became seriously ill due to an attack of arrow sores. But he didn't forget about it, the reason why Zhao Heng was still in the Northern Labor Army when Zhao Guangyi died was because Zhao Guangyi had always been worried about this matter, so he sent Zhao Heng to the Northern Labor Army, and by the way, inspect it to see if it was possible to organize another Northern Expedition.

But he didn't expect that not long after Zhao Heng left Beijing for the Northern Tour, Zhao Guangyi died, and because of Zhao Guangyi's death, the Northern Expedition naturally stopped.

But Goryeo didn't know that because Goryeo's land route to the Central Plains was blocked by the Liao Empire, every time they went to the Central Plains, they needed to cross the sea by boat, which affected the transmission of news, so Goryeo did not learn of Zhao Guangyi's death in time.

It happened that at this time, the Liao Empire went to war against the Dangxiang, which made Goryeo think that there was a war between the Liao and Song dynasties, because the Goryeo royal family did not have any reliable intelligence system, and their judgment was entirely based on the change of garrison on the border between Liao and Goryeo.

At this time, because the Liao State transferred the soldiers and horses that were originally on the Song-Liao border to attack the party, there was a certain defense void on the Song-Liao border, and in order to fill these defense gaps, it was natural to mobilize the soldiers and horses stationed between Liao and Goryeo recently.

As a result, this phenomenon was misinterpreted by Goryeo as the start of the Song-Liao war, and the Liao State transferred soldiers and horses stationed on the Goryeo border to reinforce the southern Song-Liao border.

As soon as the Goryeo royal family was overjoyed to learn of this, they raised the anti-flag and launched the most important battle against Liao.

Due to the assembly of new equipment and the unintentional attack, the early stage of the war dealt a considerable blow to the few remaining defenders stationed on the border between Liao and Goryeo.

The Goryeo army advanced smoothly into the territory of Liao, and such a situation shook the entire Liao court.

Han Derang and Empress Dowager Xiao don't know what happened this year, why the Song Dynasty died an emperor, and my Da Liao suffered one after another, how did this kind of small country and small tribe that usually dare not put a fart start to break ground on Tai Sui's head at this time.

It just so happened that at this time, Yelumo's troops happened to quickly solve the party departments and successfully returned to the court, so at this time, Han Derang and Empress Dowager Xiao didn't care about whether they could use this opportunity to turn around and attack the Song Dynasty, and it was important to solve the matter in front of them.

So Yelumo's hopes were dashed again, and he continued to lead his troops to set off, but not to attack the Song, but to quell the rebellion of Goryeo.

This counterinsurgency made Yelumo, who was bent on the Great Song Dynasty as his biggest enemy and wanted to weaken the powerful Great Liao of the Song Dynasty in everything, be greatly angered.

If it weren't for your careful Goryeo trouble, I would have arrived at the bottom of Yanmen Pass at this time.

So at this time, Yelu Mo can only be described in one word when he started the army, that is, ruthless.

It already made him very unhappy to fight the party, and now it was Goryeo again, so he took all his anger out on the Goryeo soldiers.

He will never accept surrender to those who can be killed, and he pushes all the way through, and the corpses of Goryeo soldiers are enough to make more than a dozen Jingguan.

At this time, the Goryeo royal family also reacted that something was wrong, how could the Liao State, which was at war with the Great Song Dynasty, have so many troops to deal with them at this moment.

Just when they couldn't understand, a messenger from the Great Song Dynasty came to solve their doubts, it turned out that the Great Song Emperor Zhao Guangyi had died, so there was no Northern Expedition at all.

At this time, I realized that Goryeo was already difficult to ride a tiger, and now his army was losing and retreating, and it was about to be counterattacked by Yelumo to the border.

But they could not take the initiative to sue for peace, because it was Goryeo himself who started the war. You can't say it's big, you can't say it's big, you can't fight if you don't fight.

In desperation, in order to protect themselves, the Goryeo royal family had no choice but to kill the Song envoy, and then took the head of the Song envoy to Yelumo to sue for peace.

It was hoped that the relationship with the Great Song Dynasty would be completely severed, so that the Liao State would stop attacking in exchange for the Goryeo State being able to survive.

After the Goryeo envoy came to sue for peace with the head of the Song envoy, Yelu Mo also calmed down, and at this time he already understood that even if he could bulldoze the entire territory of Goryeo, he would not be able to get the opportunity to destroy the Song.

Moreover, it is not so easy to destroy the Goryeo Kingdom, and even if it is destroyed, the subsequent rule will be a troublesome matter, since at this time the Goryeo envoy came with the head of the envoy sent by the Great Song Dynasty, it also shows that Goryeo completely severed the relationship with the Song in order to seek peace.

So at this time, Yelu Mo also got off the donkey, and after getting Goryeo's wholehearted vassals, he also stopped attacking Goryeo, got a new indemnity, and returned to the court again.

went on two expeditions and received two indemnities, although he was not able to attack the Song Dynasty as he wished, he did not suffer a loss. But in this way, the Liao State, which had spent too much time in these two wars, also lost the best opportunity to defeat the Song Dynasty.

And Da Song escaped in this way.

But although the external impact is gone, the internal changes are quietly unfolding, and Zhao Heng, who has just ascended the throne not long ago, will soon usher in his first test.
