Where is the territory once ruled by the Khan of Heaven now? Where are the people? Those Shanyus and Khans who once respected the Emperor of the Central Plains as the Khan of Heaven. As soon as the Central Plains became weak, they immediately transformed into tigers and wolves and took a bite. This title may be very tempting to another person, but to Duan Mingyu, it is worthless. Just imagine. If this is really done, then the future emperors of Khitan, as well as their civil, military and people. They will always regard the title of "Son Emperor" as a great shame and humiliation. Whenever they have the opportunity, they will start another war. Every Khitan prince, from the day he is established as prince, his greatest ambition in life is probably to Defeat the Tang State and cut off the title of humiliation. Heroes. Who is not a person who can bend and stretch. They can endure all humiliations that ordinary people cannot bear. They wait for every opportunity to make a comeback. Gou Jian even gave his wife to his enemy to warm his bed. He went to eat it himself. The enemy can do all kinds of things. What is the final result? Agreeing to this meaningless thing is just helping the Khitan to establish the goal of always making the Tang people their enemies. Duan Mingyu saw it very clearly. Agreeing to this condition is nothing different. To establish two countries, if it survives for even one day, it will be a feud. The land lost by the ancestors. If you don't have the ability to get it back, the descendants of future generations can put it aside. They can pretend to be deaf and dumb. But the "son emperor" is directly imposed on him. Title. How do you tell him to escape and endure? Only the best Shi Jingtang in his previous life would be so shameless. Negotiations between the two parties became more and more frequent. Yelu Deguang refused to make any more concessions. Duan Mingyu felt that it was necessary to use force to wake up the Khitan who still had illusions. One day, Duan Mingyu launched an attack on Yelu Deguang's camp. At the same time, he also launched an attack on Youzhou City. Li Cunxu personally directed it. A larger camp in Yelu Deguang's military camp was pulled out. Yelu Deguang was shocked. He finally began to face the unavoidable condition of the peace talks: ceding territory. But for the Khitan, the significance of the Sixteenth State of Yanyun was not limited to military matters. The Sixteenth Prefecture of Yanyun is the main farming area of ??the Khitan. It has the same effect on the Khitan Kingdom as Jiangnan has on the Tang State. At the same time, the Sixteenth Prefecture of Yanyun is an area bordering the Tang State. This is what the Khitan State draws from. The culture of the Central Plains is an important channel for integrating into the economy of the Central Plains. If the Sixteen States of Yanyun change hands, the Khitan people will return to the nomadic life of living for water and grass. The political system of the feudal empire will also be difficult to maintain. It has only been a few years since the founding of the country. The economically and culturally prosperous Khitan will go downhill from now on. The Sixteen Prefectures of Yanyun are equivalent to the economic lifeline and political foundation of the Khitan. Now Duan Mingyu takes advantage of the fact that the Khitan emperor has just died. The Khitan political arena urgently needs to be reshuffled. The military failed. In the end The second prince who was promising to ascend to the throne was trapped. Yelu Deguang was forcefully forced to cede the seven states in front of the mountain. How could he not hate it in his heart. All discussions were pending. Yelu Deguang was about to sign a letter of credence with Duan Mingyu. Emperor Zhaozong of the Tang Dynasty, Li Ye, gave Duan Mingyu has great power and is naturally qualified to sign the credentials. But Yelu Abaoji is dead. Once Yelu Deguang returns to Beijing, he will definitely be able to overthrow the eldest prince Yelu Bei and become the new king. Moreover, Yelu Deguang now holds military power in his hands. The mother-in-law of the regime said that Queen Luping must have supported him. Therefore, this letter of credence has legal effect. Yelu Deguang had long known that the cession of land was a fact. The reason why he kept delaying it with excuses was just to delay it until the cold winter. The six prefectures in the piedmont have fallen into the hands of the Tang army. This land will never come back no matter what. But Youzhou, located in the center of the seven prefectures in the piedmont, is still in the hands of the Khitan. This is worthy of scrutiny. Yelu Deguang sold it A piece of mind was added to the certificate of credence. The six prefectures in the mountains can be ceded to the Tang State. Yelu Deguang can also withdraw his troops and stop interfering. But Youzhou cannot be in vain. Duan Mingyu can't take advantage of Duan Mingyu. If Duan Mingyu captures Youzhou before the spring of next year .Then Youzhou can be ceded to the Tang State. If it cannot be conquered before next spring. Hum. Then the Tang State can only get six states this time. Youzhou can still only be in the hands of the Khitans. Duan Mingyu must also withdraw his troops. So this time The Northern Expedition was not complete. Duan Mingyu smiled faintly at Yelu Deguang. He cupped his hands and said, "Please take a seat." Everything has been agreed upon long ago. Even the contents of the credentials have been reviewed by both parties word by word. There is no need to discuss it anymore. Just take it. The temporary highest representatives of both parties who came over signed on the spot. They just used their seals. What Duan Mingyu wanted was the seven prefectures in front of the mountains, the sixteen prefectures in Youyun, the seven prefectures in front of the mountains, the nine prefectures in the back of the mountains, and the sixteen prefectures, totaling about 120,000 square kilometers. The seven piedmont prefectures guard the line of the Great Wall along the northern branch of the Yanshan Mountains and the Taihang Mountains. There are thousands of miles of fertile fields. The mountains are bounded to the north. There are many dangerous passes in the mountains and ridges. It is a natural barrier that separates the Han areas in the Central Plains and the nomadic areas in the north. The strategic location is the most important. It is the north gate of the Central Plains. Order the commander to garrison the troops and pacify the dangers. The soldiers and horses dare not go south to herd. If the Youji states are lost, the land thousands of miles away will have to fight the enemy. If the land is plain for thousands of miles, the Central Plains will always be uneasy. Duan Mingyu He believed that his 400,000 tiger soldiers would be able to capture Youzhou before the beginning of spring. He breathed a long sigh of relief. Now, his merits were finally fulfilled. But Yelu Deguang firmly believed that Yelufeng would definitely defend Yanjing City until the beginning of spring. Yelufeng's ability is not inferior to his own. He has this confidence. At this time, winter has arrived. There are less than two months left. The two parties have finalized this for the time being.??.This war was led by the Tang Dynasty. Therefore, the peace treaty was based on the Tang Dynasty's reign. They signed, sealed, and exchanged letters of credence. Duan Mingyu and Yelu Deguang each held the peace treaty in their hands. They slowly climbed up the earth-built high platform. The high platform led to the Grand Hall of the Great Hero. The eaves are still a head higher. Standing solemnly on the first step on the left are the guards of the Khitan Pishi Army, while standing on the left step are the guards of the Shence Army of the Tang Dynasty. On the high platform, there is an incense table, and the red carpet covers the ground. Except for the two of them, .There was no one left. The civil and military ministers of both countries were standing respectfully in the audience. Only the people in the living room of the two countries lowered themselves to the third level to stand. Yelu Deguang held the peace treaty in his hands. His face was pale. He looked at everything in front of him with regret. Soon The surname here is Tang. He has to stop and lead his subjects to leave here. Maybe he will never be able to come back. Duan Mingyu coughed lightly and said, "Second Prince Don't you recite the oath?" Yelu Deguang sneered. . Said: "Duan Mingyu, you have fulfilled your wish today. In the future, a certain family will definitely ask you to repay double the amount." The two of them held the peace treaty in their hands and stood solemnly in front of the incense table. Their expressions were cold and calm, and their eyes were not squinting. In the eyes of the two countries' civil and military forces in the audience. It seemed as if he was solemnly praying to heaven and earth. Duan Mingyu was silent for a while and sighed: "What will the second prince do if the two countries change places?" Yelu Deguang is after all a outstanding person of his generation. After thinking about it, he felt indignant. His mood became much lighter. He said: "You brought a pong to take advantage of the danger and forced me to cede the land. The people of the Central Plains deserve to have a good life. My son deserves to live in the open and live in the open, chasing water and grass for generations to come. Are you miserable and poor?" Duan Mingyu looked at the majestic palace of the Main Hall. He said sadly: "What can I say? Are all living beings equal? ??Even in the eyes of Buddha, who keeps saying that all living beings are equal, there are also three good ways: heaven, man, and Asura; animals, Hungry ghosts and hell are the three evil realms. There are upper, middle and lower realms in the path of good and evil. Not to mention that you and I are just mortals. Who has great supernatural powers and can take care of everyone? That is me, the Tang Dynasty. The people of the north and south, and the people of the west and east. The people of Chengzhuoshan Village and Chengzhuoshan Village are also people of the Tang Dynasty. How can they live in a beautiful place and enjoy a glorious life." Duan Mingyu said again: "I will not take Youyan today. Khitan will never be satisfied with it in the future. If you have Youyan, without Youyan, the Tang Dynasty will be flat and there will be no danger. Even if the poor people redouble their troops and expend ten times the strength, they will not be able to defend themselves." Yelu Deguang sneered: "Good reason. You take away my food. It's only natural and reasonable to give it to you. Well, I want to see if you can really capture Youzhou City within two months."
