In the spring of 1206, the Mongol nobles held a general meeting at the source of the river, and the kings and ministers presented Temujin with the honorific title of Genghis Khan.

Temuzhenshi's ascension to the throne as Emperor of the Great Mongol State was the beginning of the Mongol Empire. Genghis Khan then promulgated the Code of Genghis Khan, the world's first and most widely used written code, establishing a Mongolian aristocratic republic based on aristocratic democracy.

After Genghis Khan established the country, his power became stronger and stronger, and he implemented the thousand-household system, established an escort army, and began to launch large-scale wars of conquest against foreign countries. After more than 20 years of war with the Western Xia, the main force of the Western Xia army was repeatedly created, forcing the Western Xia king to surrender, except for the northwest barrier of the Jin Dynasty to smoothly attack the Jin State in the south.

Genghis Khan had fully prepared for the southward expedition, not only making shields and arrows, but also making a thorough battle plan.

Jin Zhangzong died of illness because he had no sons, so he passed on to his nephew Wei Wang Yongji, who was the future Jin Emperor Wei Shao. After Yongji ascended the throne, he asked the minister to send an edict to Mongolia and sent an envoy to Genghis Khan to report it.

When the envoy asked Genghis Khan to bow down and receive the edict, the great Khan of the steppe was very unhappy and asked, "Who is the new king?"

The messenger immediately said, "King Wei." ”

"Isn't that the Wei Wang Yongji?"

"Exactly. ”

At this time, Genghis Khan spit a few mouthfuls of saliva in the direction of the Jin Kingdom in the south, and then said loudly and contemptuously: "I thought that the Emperor of the Central Plains was a handsome man in the world and a man in heaven, but I didn't expect it to be King Wei?"

He turned his head to look at the envoy: "Can a cowardly person like Wei Wang Yongji also be an emperor?" After finishing speaking, he spat a few mouthfuls of saliva in succession facing the south, and then left the envoy of the Jin State, got on his horse and whipped away. This can scare the envoy of the Jin Kingdom into a momentary stunned.

This envoy was too stupid, and before returning to China, he admonished Genghis Khan in the name of farewell: "You have been rewarded by the emperor of my Dajin Kingdom, and this edict is here, you should worship it wholeheartedly, how can you say so many unreasonable words?"

Genghis Khan was furious when he heard this: "Don't talk nonsense! You Jin people are the enemies who killed my Mongol ancestors, how can I forget this sea of blood and hatred? I was about to send troops to avenge the shame, but you asked me to kneel down and accept the edict, what a bastard, get out of here quickly! Otherwise, Lao Tzu will kill you!"

With a snort, Genghis Khan drew his shiny sword, which frightened the golden envoy and ran away with his head in his arms.

It turned out that King Wei Yongji was originally the nephew of Zhang Zongwan Yan Jing, he was a man with a weak temperament, and he had gone to Jingzhou to receive Mongolian tribute on behalf of the Jin Dynasty. At that time, Genghis Khan saw that Yongji was talented, dressed very decently, tall, with a good-looking beard, and a chic demeanor, he was really a beautiful man. But as soon as he actually came into contact, he found that he was just an incompetent descendant of a nobleman, who wanted to be literate and martial, just born with a good skin.

The shrewd and capable Genghis Khan naturally didn't take him seriously, and when he saw him, he didn't kneel down and didn't treat him according to the etiquette of his subjects, which made Wei Wang Yongji very unhappy. Although Wei Wang Yongji is stupid by nature, he also has self-esteem. When he returned to the national capital, he came to a communiqué and personal vendetta, and said a lot of bad things about Genghis Khan in front of Jin Zhangzong, saying that he was extraordinary, murderous, and ambitious, and if he didn't send troops to fight earlier, he would raise tigers for trouble, so he asked Yan Jing to do it as soon as possible.

Jin Zhangzong was indulging in wine all day long, and he was plagued by illness, he was already too busy to take care of himself, where could he think so far, so he did not agree to Wei Wang Yongji's request. This time in front of the envoy of the Jin State, the reason why Genghis Khan turned his face so much was that of course there was a factor of looking down on Wanyan Yongji, but the real reason was that he thought that his wings were full and he was qualified to have the strength to compete with the Jin Dynasty.

Genghis Khan accepted and surrendered people and benefited from them, thus laying down his line of employing people regardless of nationality, regardless of country, and reusing talents without sticking to one pattern, which played an immeasurable role in his great cause of reunification. Strategically, Genghis Khan despised the resistance of the ruling group of Jin and established the belief that he would win, but in terms of tactics and pre-war preparations, Genghis Khan actually spent four or five years and attached great importance to it.

Genghis Khan clearly saw that the Jin State was, after all, a large country in the Central Plains with a history of nearly 100 years, and at that time it ruled most of the Yellow River Valley, with a population of nearly 50 million and an army of millions of people. At that time, Mongolia had a population of just over one million and a military strength of only more than 100,000 people, that is to say, the population of Jin was more than 40 times that of Mongolia, and the army was more than 10 times that of Mongolia.

Someone in the Kingdom of Jin said to the Mongols: "Our Kingdom of Jin is like the sea, and you Mongolians are only like a piece of sand, and it is more difficult to shake us than to ascend to the sky." ”

It can be seen that Genghis Khan's war to conquer the Jin country is like shaking the sea with a pinch of sand and trying to fill the sea, how difficult it is.

Genghis Khan was not only a military strategist, but more importantly a statesman, in order to seize the initiative in this war, before sending troops, he said to his generals: "For us Mongolian herdsmen, this is a very large war, the army of the Jin State, those former Jurchens, although they have been Central Plains, they still retain the characteristics of their ancestors, the Tunguska forest hunters, who are brave and fierce warriors." Therefore, this battle against the Jin people will be more difficult and complicated than the battle in Western Xia not long ago, because our army will have to deal with a well-defended fortress, and we do not have sufficient experience and conditions to carry out such a storm. In addition, there is a Great Wall of 10,000 miles on the border of the Jin Kingdom, and many defensive strongholds have been built at the foot of the Great Wall. ”

Speaking of this, Genghis Khan looked around at the generals present, changed his tone, and said loudly to them: "The current Jin Kingdom is facing a situation of internal and external difficulties and crises, just like a century-old tree, the body of the tree has been hollowed out by insects, and the land around the roots has long been frozen, there is no water, and there is no nutrition, so the branches and leaves are dry, and a yellow, wrinkled, and half-dead appearance. If there is a strong wind, the tree will most likely fall. ”

"The Kingdom of Jin is like this big tree, it has a huge appearance in the sky, and when the wind blows, it will be uprooted. Our Mongol cavalry is a lightning fast wind, we have brave warriors, there are resourceful generals, as long as everyone holds one heart and clenches into a fist to strike the enemy, the outwardly powerful Jin Kingdom will surely succumb under our horses' hooves. ”

"We not only want to be the masters of the grassland, but we also want to be the masters of the Central Plains!"

As he had said this, the guards came in and reported: "The leader of the Wangu tribe, Arawustijihuli, has sent someone to report to the Great Khan. ”

Genghis Khan hurriedly commanded: "Let the man come to the inner tent, and I will see him." ”

In the inner tent, a person from the Wanggu tribe reported: "The new emperor of the Jin State, Wanyan Yongji, has made arrangements to wait for the Great Khan to go to the Jin State to pay tribute, ambush heavy troops, and snipe the Great Khan." ”

It turned out that the envoy of Wanyan Yongji returned to the capital of the Jin Kingdom, and reported that Genghis Khan not only did not bow down to accept the edict, but spat and insulted the new emperor in the south, and added fuel to the vinegar, and the old hatred and new hatred of the Yongji Emperor came to his heart at the same time, and he was even more annoyed with Genghis Khan, and he couldn't help but grit his teeth and say: "What's so great about little Mongolia that dares to oppose our great Jin Kingdom? When Genghis Khan comes to pay tribute again, I must take him and break his body into thousands of pieces, so as to relieve the hatred in my heart." ”

Unexpectedly, these words of the emperor were heard by the ministers, especially those who were not from the Jurchen tribe, and immediately spread the news, and the leader of the Wangu tribe, Arawusi Tijihuli, found out the news, and immediately sent someone to report it to Genghis Khan.

This time, the leader of the Wanggu tribe, the people sent by the leader of the Wangu tribe, Aravus Tijihuli, also told Genghis Khan a piece of news that the main soldiers of the border army guarding the first line of the Great Wall in the northwest of the Jin State were people from various ethnic minorities. Because the rulers of the Jin kingdom did not trust them, they looked at them differently, and often did not pay them on time, so the army was very resentful, and the leader of the army, Ilguk, often complained in front of the Aravuti Tiji.

When Genghis Khan heard this, he was overjoyed, and hurriedly found his intelligence captain Zabal, and asked him to bring a large amount of gold and silver with the people from the Wanggu tribe, and asked Aravus Tijihuli to mediate and do the rebellion of the army. After Zabal and the others left, Genghis Khan thought about it and always felt that the Wanggu tribe was too important to Mongolia, especially in this war against the Jin State, this Wanggu tribe became the vanguard of the Mongolian army.

Wouldn't it be more beneficial for Aravus Tijihuri to persuade the Jin army to surrender once he could persuade the Jin army to surrender?

Thinking of this, Genghis Khan felt that the opportunity could not be lost, and the time should not come again, and he should seize the current great opportunity, firmly grasp the Wangu tribe, and make it more loyal to himself. Genghis Khan always said that he would do it, and he immediately ordered the guards to call for Shifter and asked him to escort the third princess Arahe Beiji to the Wanggu tribe. He also asked him to learn as much as possible about the border defense situation in the northwest of the Jin Kingdom from the Wangu tribe, and it was best to let the Alawusi Tijihuli send the Wanggu tribesmen to go deep into the Jin Kingdom to spy on military intelligence.

The next day, Genghis Khan brought Mu Huali and Borshu again, and made plans to send troops to attack the Jin State, and the three of them closed the tent door and discussed for a whole day.

In February, Genghis Khan held a unique mobilization for war on the banks of the Krulun River in his old camp, and according to the Mongol custom, he climbed to the top of the mountain alone, took off his hat, hung his belt around his neck, respectfully bowed to the heavens three times, and then got up and prayed: "Immortal Heaven is above, I am determined to straighten out my army and horses, and avenge this blood and vengeance for the Ghbol Khan and the Baba Khan who were despicably killed by the King of Jin." If the heavens allow me to take revenge, then please help me and order all the gods of the nether world to gather and help me fight. ”

After praying, Genghis Khan entered the palace tent again and closed the door for three days. During these three days, the Mongolian soldiers and civilians gathered around the tent and shouted in unison: "God, God, help Mongolia!"

"Heavenly God! Heavenly God! Punish Jin Guo!"

It was not until the fourth day that Genghis Khan came out of the palace tent and mobilized before the battle. So Genghis Khan personally led the Mongol army of 100,000, let the nine-legged banner lead the way, and his four sons and all the other generals joined the army in the battle, and marched mightily to the southern kingdom of Jin.
