One hundred and seventy years ago, the Liao State destroyed the Bohai State, and the Liao Taizong Yelu Deguang moved a large number of Bohai remnants to Liaodong, and for a time the vast Bohai Sea became vast and sparsely populated.

The westward movement of the remnants of the Bohai Sea weakened the power of the Liao State here, weakening its control over the former Bohai region, especially the Jurchen region in northern Goryeo.

Goryeo took the opportunity to lure and drive away the Bohai people and a small number of Jurchens under the original Bohai rule, and continued to expand its power, and even began to send troops to fight fierce battles with the Jurchens under the control of the Liao Dynasty.

Wang Jian changed the name of Pyongyang to Xijing on the pretext of defending against the Jurchen invasion, and sent his younger brother Wang Shilian as a commander to garrison it. In the early years of the Goryeo Dynasty, the governor of Pyongyang, Seogyeong, had a great deal of power, and he was only responsible to the king himself, and the appointment and dismissal of his subordinate officials was entirely at the discretion of the governor himself.

On the one hand, Goryeo actively managed Xijing, and on the other hand, it built the cities of Deokchuan, Changqing, and Anshuo north of the Qingchuan River, pushing the border between Goryeo and the Liao State from the Daedong River to the Qingchuan River; at the same time, it actively attacked the Jurchens living along the Yalu River and encroached on the Jurchen homeland.

In order to defend against the Liao State, Goryeo established the Guangjun Division, which was organized into 300,000 Guangjun. At the same time, Wang Jian adopted a strategy of immigration to Sibian and moved a large number of people from the southern part of Goryeo to the north.

These measures by Wang Jian strengthened the border defense force in northern Goryeo and greatly expanded the land area. Wang Jianjing's pace to the north did not stop for a moment. By the end of his reign, the northern border of Goryeo had reached as far as the southern banks of the Yeongheung and Cheongchon rivers, and its territory greatly exceeded that of Silla.

Song Taizu Jianlong in October of the third year. Wang Jian's son, Wang Zhao, sent his Guangping attendant Li Xingyou, deputy envoy Li Lixi, and judge Li Bin to the Song State to pay tribute.

About 100 years ago, after the Liao State conquered Goryeo for the first time, Goryeo was defeated and forced to pay tribute to the Liao and cut off diplomatic relations with the Song, and the Liao gave Goryeo "hundreds of miles east of the Yalu River". Goryeo led troops to expel the Jurchens and built the six cities of Xinghua, Tiezhou, Tongzhou, Longzhou, Guizhou, and Guozhou.

After another decade, the territory of Goryeo has expanded to the area around the Yalu River. From 60 to 50 years ago, Goryeo built the Great Wall between the south of Hamhung and the north of Yongheung. Arrive at the capital of Lianpu, and build Dingzhou, Xuande, Yuanxing three passes. Since then, the Liao Kingdom and the northeastern part of Goryeo have been bounded by the Great Wall and Sanguan along this line.

Now. Goryeo raised troops to cross the Great Wall and the three passes, invaded the Liao Jurchens' Haoladian area, and forcibly built nine cities, which was really a wolf's ambition. Abundantly clear.

On the way to the undefeated march in the East. The garrisons from all over the country have joined one after another, and before Liaoyang Mansion has passed, the number of troops has exceeded 200,000, and it must not be a problem to gather twice the number of soldiers on the eastern border.

But just halfway through, the front line was full of successes.

It turned out that in the face of the invasion of foreign enemies, the head of the alliance of the Wanyan Ministry was impeached. Send the second son Aguta to lead the soldiers and horses of various tribes and meet in Tongzhou. These warriors of the Wanyan tribe. Although the total number is only 2,500 people, it is extremely combative.

Aguta led the soldiers to sacrifice to heaven and earth, and swore an oath, saying: "Everyone work together, meritorious slaves and maids can be commoners, and commoners can be officials." Those who previously held official positions may be promoted according to their merits. If the oath is broken and the person dies, the family cannot be pardoned. ”

The next day, they arrived at the front line and met the Goryeo army. Ah Gu shot the enemy general Li Longhai. The Goryeo soldiers were defeated, and seven or eight out of ten were killed.

Three days later, the Jurchen soldiers took advantage of the victory to conquer the Goryeo garrison outside the city of Luzhou, captured a large number of horses and property, and returned to the division in victory.

Next, the Jurchen warriors were out of control, and within a few days, they pulled out nine walled cities built by the Goryeo people, recovered Haolaidian, and continued to move south, breaking through the three passes of the Great Wall of Goryeo with Dingzhou, Xuande, and Yuanxing, shouting that they would attack Xijing, and then go to Kaijing to set fire.

Dongfang Undefeated looked at the battle report full of brilliant victories in his hands, but the surprise in his heart was extraordinary: "No wonder the Jin army composed of Jurchens can create a miracle of destroying Liaoping and Song in only twelve years, and their combat effectiveness is truly terrifying." Thinking back then, oh, no, it should be said that later, the Liao Tianzuo Emperor personally led the Liao army known as 700,000 to fight against the 20,000 Jin army of Aguta, but was still defeated and lost, I finally understand why. ”

He bowed his head and pondered for a while, and then muttered to himself: "The atrocities of the Goryeo people's brazen invasion of our country are certainly abominable, but if Aguta leads his Jurchen soldiers into Kaijing, burns a huge capital city, and displaces thousands of people, it will be an even greater atrocity." I'll still give a military order, so that he can only attack the city and not slaughter it!" Then he took the pen and wrote the order, and asked the herald to ride a fast horse to send it to Ah Gu.

But before Aguta received the military order of Dongfang Undefeated, Dongfang Undefeated had already received a letter from Wang Hao, the king of Goryeo. The letter said that Goryeo's invasion of Daliao this time was the result of the self-initiative of the border guards, and not the intention of the king and the imperial court of Goryeo.

The two generals who provoked the incident had been beheaded, and their heads were sent to the hands of Dongfang Undefeated along with the national letter, and she was also asked to lead the troops out of Goryeo without remembering the villain's mistakes.

Dongfang Undefeated read the surrender letter, looked at the two bloody heads, and immediately laughed and said: "Hmph, take it upon yourself to march without permission? Who are you fooling! Not to mention whether the two generals stationed on the frontier have the courage to start a war with the outside world without telling their own masters, just by looking at their march routes, we can see that this is a well-planned and well-arranged military operation, and then it has the support of the entire Goryeo Kingdom. ”

Goryeo has always pursued a policy of "doing great things to protect the country", and its army surrendered immediately after defeating the enemy, so as to play with other countries, and thought that it was a good show, but the East was undefeated in the eyes and quite dismissive.

"Well, since Goryeo has already sued for peace, then we are also victorious, and we still have to give them a step down. "The East is undefeated and thinks again.

After reporting to the Liao court and getting approval, Dongfang Undefeated gave Wang Hao four conditions for surrender: first, Goryeo gave up the Jurchen homeland east of the Yalu River that it had previously occupied; second, Goryeo compensated the Liao military expenses of 300,000 taels of silver; third, the king of Goryeo Wang Hao personally went out of the city to surrender, and the undefeated Dongfang would rush to Kaijing to surrender; fourth, the Liao Emperor sent an envoy to Goryeo to give the seal, thus establishing the suzerain-vassal relationship between the two countries. The annual coin is fixed as a tribute four times.

At this time, the Jurchen army led by Aguta, and the combined forces of the Han, Bohai, Khitan, Murowei, Tieli, and Wuja tribes, totaling no less than 100,000 people, had already approached the capital and surrounded it.

In the face of the almost harsh surrender conditions offered by Dongfang Undefeated, and the more than 100,000 imposing Liao troops outside the city, Wang Hao discussed with a group of courtiers in the court for several days and nights, and begged Dongfang Undefeated to send people to negotiate.

After receiving a reply from the Goryeo court, Dongfang Undefeated agreed to negotiate with the other party, and also sent his own capable general Zhao Hanqing to negotiate. (To be continued......)
