Genghis Khan's three armies swept through the Central Plains, and after returning with a full load, they met in the old military camp north of the central capital.

In the past year, Genghis Khan's soldiers and horses captured the vast territory of the Jin State, but did not garrison the occupation, after the plunder, left the Jin State with empty cities, seeing that the generals were arrogant one by one, and regarded the capture of the capital as a bag, and asked to take advantage of the victory to attack the city.

But the clever Genghis Khan had his own ideas, he once again refused the request of the soldiers, and patiently said to them: "The walls of this capital are strong, and the number of soldiers defending the city is large, although there are many internal contradictions in the Jin Dynasty, but the hundred-legged insects are dead but not stiff, and they still have a certain ability to resist, so it is better to come to the city with troops first and strive for some practical benefits." ”

In fact, from a strategic point of view, Genghis Khan knew that the Jin State was vast and crowded, and even if he could destroy the ruling power of the Jin Dynasty in one fell swoop, he would not be able to control the huge territory of the Central Plains, so it was better to use attrition tactics, gradually attack and plunder, hollow out the Jin State again and again, making it an empty shell with an empty appearance, and then explore the ruling method after the destruction of the Jin State, it is not too late.

Under the domination of this thought, Genghis Khan immediately sent an envoy to enter the central capital and said to Jin Xuanzong: "I am ordered by Genghis Khan to convey to the emperor of Dajin what he wants to say to you, at this time, the prefectures and counties of Shandong and Hebei have all been owned by Mongolia, and what you hold is just a lonely city in the central capital. Heaven has weakened you, and I will no longer persecute you, and we will withdraw now, do you not want to reward my soldiers and appease their anger?"

Jin Xuanzong was already afraid of the enemy, so he had to accept Genghis Khan's peace conditions. Jin Xuanzong sent Wanyan Chenghui as a peace envoy, and the gifts he brought were 3,000 war horses, 3,000 embroidered clothes, and a large number of gold silk property.

After Genghis Khan received these gifts, he asked, "Our army is enough, and you Emperor Dajin should have children, why don't you send them to serve Ben Khan?"

After Yan Chenghui listened, Wei Wei obeyed the order, immediately returned to the central capital, and conveyed Genghis Khan's request to Emperor Xuanzong, and after repeated discussions, he dressed up the daughter of King Weishao Wanyan Yongji, pretending to be the daughter of the emperor Wanyan Jing, and gave it to Genghis Khan, which is the famous princess and queen in history. At the same time as the princess of Qiguo, there were 500 boys and 500 virgins, as well as a large number of dowry gifts.

This princess of Qiguo, sixteen years old, has been smart and clever since she was a child, loves to read scriptures and history, piano, chess, calligraphy and painting, and is good at everything. She has a disfigured face, a prominent forehead, eagle eyes, a hooked nose, high cheekbones, thick lips, a loud voice, a slender figure, and long thin and black hair.

According to her mother, Mrs. Yuan, "After the princess of Qiguo gave birth, a monk came and gave her a small silver lock to hang on her chest. When the monk was leaving, he said, "Your daughter has a different face, and she will marry a rich and noble person, and this silver lock can only be opened by the princess's husband." ”

When the princess of Qiguo came to the Mongolian camp, Genghis Khan was immediately attracted by her strange appearance, and could not help asking, "Why is your appearance different from that of other Han women? ”

The Mongols collectively called the Han people, Khitans, Jurchens and others Han people, so Genghis Khan called her the Han princess. After listening to Genghis Khan's question, the princess did not answer in time, but untied the silver lock from her neck, handed it to the Great Khan, and relayed the monk's words to him. When Genghis Khan heard this, he felt a little strange, so he put the silver lock in his hand, examined it repeatedly for a long time, and then opened it, and saw two lines of small characters on the inner wall of the silver lock, and he asked the Han princess to read the small words on the lock to him.

"Those who convince others with virtue will win the world, and those who convince others with strength will lose the world." ”

Princess Han also saw these two sentences for the first time, she thought for a while, and then explained the meaning of the two sentences to Genghis Khan. The Mongols especially worship the landless gods, Genghis Khan has always believed in the blessing of God and the help of God, and now seeing the miraculous origin of the silver lock of the Han princess, I can't help but have a sense of piety in my heart, and I respect the princess even more.

Genghis Khan took the sixteen-year-old Han princess in his arms and said warmly: "I have a princess and queen who is proficient in Chinese. "This night, Genghis Khan and Princess Han were in love.

Genghis Khan triumphantly ended the third attack on Jin, returned with a full load, not only swept the hinterland of the Central Plains of the Jin State again, but also broke through the local government of the Jin State.

Due to the destruction of the urban and rural economy, the displacement of the common people, and the fact that the financial and military resources have been almost exhausted, it has really hollowed out the Jin State, causing the imperial court to suffer the most serious destruction, and it is no longer possible to restore it to the pre-war level in a short period of time.

What was particularly serious was that during the war, wherever the Mongol army went, the policy of killing those who resist and exempting those who surrendered was widely implemented, on the one hand, many generals who resisted stubbornly were killed, and on the other hand, more generals surrendered. For the Khitan and Han generals who surrendered, Genghis Khan often gave them old positions, and even added officials to knighthood, giving them all kinds of preferential treatment.

After the Mongol army retreated, most of them stayed where they were, supported the army and divided the territory, and became the henchmen of the Jin state, and some openly confronted the Jin army, which made the Jin dynasty fall apart. Faced with the crisis-ridden national situation, the Jin court had to consider the way out in the future.

In Mongolia, which was just the opposite of the Jin Dynasty, Genghis Khan led the soldiers and horses to return to the old camp of the Krulun River in triumph, and continued to celebrate and share the rewards, several piles of spoils as high as a hill were divided into two clean, and the soldiers were happy, and for several nights, the banks of the Krulun River were full of people singing and dancing, everyone gathered around the bonfire, playing dombra and the six-stringed harp, celebrating the victory.

A few days later, Genghis Khan convened a meeting of his generals, and he said: "In these three successive attacks on gold, the soldiers all thought that the land of the Central Plains was like a piece of fat, and oil flowed from the corners of their mouths when they took a bite. In fact, there are a lot of gold and silver treasures in the central capital, but if it reaches the Song Dynasty, the banks of the Yangtze River will be even richer. ”

"There is heaven above, and there is Suzhou and Hangzhou below, and this Suzhou and Hangzhou are in the territory of the Song Dynasty, and the capital of the Song Dynasty is not in Hangzhou? However, there are cities with strong walls everywhere in the Central Plains, and it is difficult to break through in a short time by relying on our cavalry alone, and the best siege weapon is artillery, but we don't have it, I want to establish an artillery team, please express your opinions. ”

Senior General Jebe was the first to speak: "To build an artillery corps, I raise my hands in favor. When we attacked Jin for the first time the year before last, our army was bombed badly by the artillery of the Jin State under the Zhongdu City. The soldiers were blown up and lost their arms and legs, and some of them could not even find the corpses in the capital, not only did the city not take it, but even the Great Khan was wounded by flowing arrows. In the end, I had no choice but to retreat. Later, the two attacks on the Jin State, although the army was stationed under the Zhongdu City, a piece of fat was visible to the naked eye, but it could not be eaten, the main reason was the lack of siege ability, to make it clear, that is, our army did not have artillery, otherwise there were ten Zhongdu cities would have been captured earlier. ”

The general An Muhai said: "I thought that the siege of the city should be carried out by artillery, because it is powerful, a cannonball can blow up a large area, and it can attack far, and the cannonball hits, and the enemy will be killed before he sees us." ”

Genghis Khan said approvingly: "This has come to my heart, the two great advantages of the cannon, one is powerful, and the other is the long range, which our iron cavalry cannot do. However, this cannon can't be separated from skilled craftsmen, one must be able to build, two must be able to release, and three must be able to repair, which is not easy to do. ”

An Muhai said: "As long as the Great Khan gives an order, the cannon will definitely be built." ”

General Borshu said: "When I attacked the Jin Kingdom the year before last, I once captured alive a cannon master of the Jin Kingdom, his name was Jatarahun, and he was treated favorably at that time, and he was not imprisoned, and let him escape. I heard that this person fled into the Taihang Mountains, saying that he lived in Lin County, but because there was other military affairs at that time, he could not be arrested. ”

Otun Shiying, the general of the Jin Kingdom, said: "This artillery master Jia Ta Rahun, a famous gunner of the Jin Kingdom, has had a friendship with me, and asked the Great Khan to send me to Lin County and invite him here." ”

When Genghis Khan heard this, he immediately responded: "Well, if you go and invite him, we will definitely use him, believe him, and make him live ten times better than in Jin." ”

General Mu Huali reminded: "It is recommended that you dress up as a businessman and ask the entourage to bring some gifts and money, when he promises to come, it is better to move his whole family here, wouldn't it be safer?"

Genghis Khan added: "For the sake of safety on the road, let Hercules Fanlu go with you, he is a good bodyguard." ”

After everyone finished speaking, Otun Shiying said goodbye to Genghis Khan and went to prepare a gift to Linxian County in the Taihang Mountains.

At this time, Zhao Wanggui, the general of the Jin Dynasty, said: "As far as I know, there are still many people in the Jin Kingdom who know how to make artillery, Xue Talahai of Fuzhou and Zhang Batu of Changping, both of whom are living in the same place, wouldn't it be a good thing to ask the Great Khan to send someone to invite them?"

When Genghis Khan heard this, he hurriedly asked, "I wonder if anyone knows the two of them?"

Shi Bingzhi and Tian Qinghe stood up together, saying that they knew the two artillery divisions, and Genghis Khan immediately sent the two back to prepare, and quickly went to Fuzhou and Changping to invite the two to Mongolia.

Hazar said: "In my team, there is a Cheongju man named Zhang Rong, he not only knows how to make artillery, but also can build ships, build bridges, etc., I will go back and ask him again, okay?"

Genghis Khan complained: "Why didn't you say it earlier? He has skills, and if we don't need him, won't we bury a capable person? ”

After Hazar left, Genghis Khan said with infinite emotion: "Let me tell you, some people regard gold and silver as treasures, that is short-sighted and unambitious, and the best treasure in the world is people." ”

At this point, Genghis Khan said to his subordinates in a tone of emphasis, as if he were an order and as if he were an admonition: "In the future, all skilled craftsmen who surrender and those who know all kinds of techniques must be given special preferential treatment, and all skilled craftsmen who have conquered the city will be pardoned and not killed; ”
