Li Zhi left, not only left Baozhou, but also completely left Goryeo, because Goryeo did not listen to the dissuasion of the Great Song Dynasty, and wanted to send troops to attack the Liao State, and wanted to expand his sphere of influence to the west side of the Yalu River, which made the Great Song Dynasty also very dissatisfied, so not only withdrew the aid to Goryeo, but also withdrew the envoys stationed in the country.

But even so, it still failed to discourage Goryeo's determination, in fact, as Li Zhi observed, the whole of Goryeo has fallen into a kind of frenzy, as a small country, they have been living in the shadow of the Liao State, always worried that the Liao army will kill to destroy their country and slaughter their people, in fact, the Liao State has more than once slaughtered Goryeo, and countless Goryeo people have died tragically under the iron hooves of the Liao.

But now they have not only defeated the Liao army, but also recovered the lost land, especially the rumor about the decline of the Liao state, which makes them feel that this is a once-in-a-lifetime opportunity, and even regain the glory of Goguryeo.

It may be difficult for outsiders to understand this kind of fanaticism of the Koreans, but in fact, if you think about it, the Koreans are like a small man who is usually bullied, but suddenly one day, the big man who bullied him is sick, and he is easily defeated, which will definitely make the little man extremely confident, and the resentment accumulated before will all explode at once, and he will naturally redouble his revenge and return all the humiliation he suffered before.

On the third day of Li Zhi's departure, with the order of the Goryeo king Wang Heng, the 100,000 Goryeo army crossed the Yalu River majestically and proudly, and killed Tokyo, one of the kings of Liao.

However, the reality is very cruel, just when the army of the Goryeo people just killed under the city of Tokyo, but did not expect that the city of Tokyo, which was not much garrison, suddenly killed tens of thousands of Khitan iron cavalry, and a charge killed the army of the Goryeo people, and then 100,000 Goryeo people were pressed on the ground by the Khitan iron cavalry and rubbed, and finally less than 3,000 could escape back to Jiangdong, after all, not all the troops who crossed the Yalu River could be compared with the volunteers of later generations.

The defeat of the Goryeo people was too fast, in addition to their light enemy, the Liao army's surprise attack also took a great advantage, this is mainly because the Goryeo people did not expect that there were so many cavalry stationed in the city of Tokyo in the Liao country, according to the situation they got before, there were only 5,000 garrisons in the city of Tokyo, so they attacked Tokyo with 20 times the force, and they were still very sure.

However, all this came too suddenly, for a small country like Goryeo, the 100,000 army almost exhausted the strength of the whole country, but it was lost in one day, and what made the Goryeo people even more frightened was that after the Liao army destroyed their army, it did not stop, but crossed the Yalu River along the pontoon bridge, and recovered the lost six states of Jiangdong as quickly as possible.

Wang Heng, who was originally staying in Baozhou, also fled to the rear quickly, and the poor Koreans took Baozhou for a few years, and they didn't even cover the heat in their hands, but they were returned to it, and the footsteps of the Liao army did not stop in Baozhou and other places, but chased Wang Heng, a group of Goryeo monarchs and ministers, all the way to burn, and finally killed the capital of Goryeo Kaijing a month later.

Kaijing as the capital of Goryeo, as early as the reign of Wang Heng's father Wang Xun, that is, when the second Khitan Goryeo War broke out in history, Kaijing was once broken by the Liao army, it is also a bit strange, Kaijing as the capital of Goryeo, but there was no city wall before, so there was no way to defend in the face of the Liao army, and the result was easily killed by the Liao army, and the entire Kaijing was also caught in a war.

With the lesson of the last time, so when the Goryeo people rebuilt Kaijing, they specially built a thick city wall for Kaijing, so when the Liao army killed under the city of Kaijing this time, it was temporarily blocked by the Goryeo people under the city, after all, although the elite of the Goryeo people died under the city of Tokyo in the Liao State, but there are still a lot of troops stationed in the national capital, these garrisons rely on the tall city walls, and the Liao army is not good at attacking the cavalry, so it is naturally difficult to take here for a while.

If it was placed in the past, the Liao army might not have been delayed for too long here in Goryeo, after all, there is no value of occupation here in Goryeo, and when they killed Kaijing, the rear front had been stretched for a long time, and if there were Goryeo people making trouble behind their backs, it was likely to destroy their supply lines, so the last time the Liao army attacked Kaijing, they just looted and left, and even when they encountered stubborn resistance in Goryeo Xijing, they also directly bypassed Xijing, which can also give full play to the greatest advantage of the Khitan iron cavalry.

However, this time the Liao army seemed to be determined to defeat Kaekyung and even destroy Goryeo, so in the face of the resistance of the Goryeo people, the Liao army did not retreat, but launched a more fierce attack on Kaeongseong, and the Goryeo people also knew that they had reached the moment of life and death, so the defense was also very resolute, and the two sides were at a stalemate for a while.

Tokyo Bianliang, when Zhao Zhen told Li Zhang the news of the Liao army's invasion of Goryeo, Li Zhang also showed a surprised expression, not surprised by the defeat of Goryeo, in fact, long before Goryeo decided to send troops, they had already expected the end of the Goryeo fiasco, after all, the emaciated camel is bigger than the horse, no matter how weak the Liao State is, it is not something that a small country like Goryeo should covet, but the Goryeo people were overwhelmed by the victory, and even had a feeling of arrogance in Yelang, thinking that the Liao State was nothing more than that, and as a result, the head of the 100,000 army was sent.

It's just that Li Zhang didn't expect that the Liao army would be killed until the opening of the capital, and he also had a posture of not breaking the opening of the capital and not returning it, which is a bit surprising, after all, the current situation of the Liao State is not very good, and the internal situation has not been stabilized.

"Cousin, I discussed the matter of Goryeo with Lu Xiang and them, and finally agreed that Liao is likely to feel the crisis around him, so he wants to solve Goryeo first, so that he can concentrate on dealing with our threat." Zhao Zhen said at this time.

"It is very likely that the west and south of the Liao Kingdom are our army, and the Jurchens in the north are not worrying, in contrast, only the Goryeo people in the east are the easiest to deal with, and if they destroy the Goryeo, there will be one less threat." Li Zhang also showed a sudden expression when he heard this.

"Then do we want to help Goryeo?" Zhao Zhen immediately opened his mouth and asked, although Goryeo did not listen to their advice before, it was still useful to the Great Song Dynasty, if he watched Goryeo be destroyed now, it was not in the interests of the Great Song Dynasty.
