After the Jin Dynasty, a large country in the Central Plains, was plundered by the Mongol army three times, the country was hollowed out, the economy withered and depressed, the people were displaced, the army was centrifuged, and the court was shrouded in a negative and pessimistic mood.

After a long period of consideration, the Jin Emperor Wanyan Jing decided to move the capital to avoid the invasion of the Mongol army, and he said to the Minister of Civil and Military Affairs: "Since the three invasions of the Mongols, the national strength has weakened, the soldiers have no fighting spirit, the wealth is lacking and the people are poor, it is impossible to stick to Zhongdu, it is better to move the capital to Bianjing." ”

One stone stirred up a thousand waves, and Jin Xuanzong's words of moving the capital immediately aroused a lot of discussion among the civil and military forces of the Manchu Dynasty, and many ministers opposed this kind of escapist behavior.

In a fit of anger, Tu Danyi actually wept bitterly in the court, crying, and pointed to Xuanzong and said: "The great golden kingdom has been corrupted by you incompetent faint kings. How can we be courtiers who have the face to live in the world, rather than living in humiliation, it is better to die in dignity, but to leave a clean name. ”

The Prime Minister Zuo stood up, aimed at the big wooden pillar on the court, and hit his head, Tu Danyi immediately burst out of his brain and died on top of the court. The civil and military ministers of the Manchu Dynasty were in an uproar, and Jin Xuanzong also felt that the incident happened suddenly, and he was at a loss for a while, and after a while, he asked the guards to carry down Tu Danyi's body and ordered him to be buried thickly. Although Tu Danyi gave a death reprimand to move the capital, it still could not change Jin Xuanzong's decision to move the capital, because the emperor had already been frightened by the Mongol cavalry, and he had already made up his mind to escape by smearing oil on the soles of his feet.

Jin Xuanzong appointed Wanyan Chenghui as the right prime minister of Shangshu, and Mo Ran was loyal as the left deputy marshal, and asked them to assist the crown prince Wanyan Shouzhong to stay in Zhongdu, but he fled to Bianjing with hundreds of civil and military officials and concubines and palace maids, so that the Jin State embarked on a road of accelerated demise.

When Genghis Khan got the news, he said excitedly: "Heaven help me, this time the central capital will be broken by our army." ”

Genghis Khan immediately convened a military meeting and said: "Since the emperor of the Jin Dynasty has reconciled with me and decided to get along amicably, and now he has broken the contract and moved the capital south and openly sabotaged the peace talks. ”

So Genghis Khan sent an envoy to the Jin Dynasty to ask the reason for moving the capital. Alaqian hurried to Neiqiu County, Hebei Province, only to see Jin Xuanzong, conveyed Genghis Khan's scolding, and declared that since peace was made, the capital should not be moved, and the move of the capital was a manifestation of distrust of the Great Khan. When Jin Xuanzong heard this, not only was he not angry, but he also explained again and again, but he still continued to advance towards Bianjing, and it was impossible to change the intention of moving south.

In this way, the dark clouds of war once again shrouded the sky over the Jin country, Genghis Khan never let a good opportunity slip in front of his eyes, not to mention the evacuation of the capital last year, is waiting for the arrival of the opportunity, and now the opportunity that can not be asked for has come, and he is overjoyed, but he angrily blamed the other party for providing this good opportunity, and should not move the capital south, so he should raise troops to ask for the guilt. A discerning person can see that this is obviously just looking for an excuse to raise troops to attack the Jin Kingdom for the fourth time.

Genghis Khan ordered the general Mu Huali to lead an army of 60,000 men to attack Jin for the fourth time. In this attack on the Jin State, in addition to the brave and warlike cavalry, the Mongol army also had a newly established artillery team, as well as the newly surrendered Mongolian army, most of which were composed of Khitans and Han Chinese, who were brave and good at fighting and had great combat effectiveness.

Mu Huali set out in March, only two months, first cleared the Jin soldiers on the periphery of the central capital, and then used the siege strategy to eliminate the living force of the Jin soldiers, and captured the central capital without a single soldier, and successfully won the great victory of the fourth gold campaign.

Mu Huali sent Shi Mo Ming'an and Sanmu Heba to lead troops into the city, forbidding plundering to the people in the city, and allowing the soldiers to trade the plundered grain and livestock in the city, so that the hungry people could get food and the soldiers could get property.

Then Mu Huali sent people to report the good news to Genghis Khan: "The whole army entrusted Genghis Khan's Qi Tian Hongfu, and we captured the capital of the Dajin Kingdom. ”

When Genghis Khan received the report, he was overjoyed, and he had not drunk for many days, and immediately drank three cups to celebrate.

At that time, Genghis Khan was taking refuge in Liangjing, Huanzhou, and immediately sent the chief magistrates to the central capital to comfort the soldiers and be responsible for cleaning up the treasury property. At this time, the central capital city was not as big as today's Beijing City. Under the rule of the Jin Dynasty, the central capital was confined to the outer city of Beijing, which is the southern part of present-day Beijing.

Despite this, the central capital at that time was still one of the largest cities in the world. At that time, the surrounding city wall around the middle capital was more than 80 miles long, there were 12 city gates, and the city was divided into four small cities. The imperial palace of the Jin Dynasty was located near the Temple of Heaven, as well as a summer palace, located on the side of the White Pagoda Temple near Beihai. This palace for the king of gold to stay in the summer, it is surrounded by the inner city, is a huge park for the king to spend time and entertainment.

Genghis Khan was worried about the resurgence of the Jin Dynasty army, and after thinking twice, he sent someone to convey the order to Mu Huali to destroy the central capital. So the Mongol army immediately set fire to the palace and burned it for more than a month.

Genghis Khan was only concerned with how to receive the treasures in the treasury of the Jin Dynasty after the capture of Zhongdu, namely gold, silver, jewelry, silk, etc. At that time, one of the generals in charge of the treasury of the whole country, named Heda, heard that the Mongols had sent three generals to receive the treasures, and he hurried to meet them in person. In order to curry favor with these three generals, he took several pieces of silk fabrics embroidered with gold and presented them as personal trophies.

Hazar and Wangur were attracted by this precious silk fabric, and accepted the gift, but the nobleman, who was the chief magistrate, behaved very decency, and he sternly refused the bribe-like gift, and replied to him: "All the treasures in this capital belonged to the king of Jin, but now all the treasures in the capital have been occupied by our Mongols, and all the property belongs to Genghis Khan." As a general, how dare you dispose of these treasures that belong to Genghis Khan without permission? It is really bold for you to give us these treasures at will, and I will never be rare in these goods, so you can take them back. ”

Lost begging and bleak at this moment, he was so frightened that he fled back with the embroidered gold silk fabric. Soon after, when the three of them returned to Genghis Khan on business, the Great Khan knew the human psyche very well, and when he saw the three of them, he suddenly asked them: "What gift did that Heda give you?"

Hazar and Wangul had no choice but to tell the truth, and took out the gold-embroidered silk fabric and showed it to Genghis Khan. While watching, the Great Khan exclaimed: "Good, it's really ingenious, and it's priceless." ”

Suddenly, Genghis Khan saw that he was empty-handed, so he asked, "What gift did Heda give you?"

He had to say: "He also gave me this embroidered gold silk fabric, but I refused, but I didn't ask for it." ”

When Genghis Khan heard this, he asked with great interest: "Why did you refuse to accept his gift?"

He immediately replied: "I thought that before the capture of the central capital, a rope and a handkerchief in the treasury belonged to the Emperor of Jin. Now that the city has been taken by us, everything should belong to the Great Khan, how can others take possession of it at will?"

When Genghis Khan heard this, he couldn't help but love him from the bottom of his heart, and admired his integrity and integrity and unusually noble and precious conduct.

As the saying goes, "See the subtlety in the subtleties, and look at the style in the bits." The refusal to accept this piece of embroidered gold silk fabric fully shows the high wind and brightness of begging and baldness.

Thinking of this, Genghis Khan blurted out and praised: "What a beggar, you are really knowledgeable, cautious in your duties, and a loyal servant of mine, I hope you will always be my eyes and ears." ”

At the same time, Genghis Khan took advantage of the favorable situation of the capture of Zhongdu and immediately sent an envoy to Bianjing, the new capital of the Jin Dynasty, and put forward the conditions for the withdrawal of troops: "Take the initiative to sacrifice the cities of Hebei and Shandong that have not yet been occupied by the Mongol army, and Jin Xuanzong will personally go to the emperor and call him the king of Henan." ”

This condition was actually to force the Jin State to declare that it would die without a fight, so how could Jin Xuanzong agree? So he refused to accept this surrender condition, and the envoy returned to Mongolia to report, and Genghis Khan immediately ordered a surprise attack on Bianjing of the Jin State. However, Bianjing was protected by the Yellow River, and if the Mongolian cavalry wanted to cross the Yellow River, because there were no large number of ships, they could only look at the river and sigh.

After consulting with his generals, Genghis Khan decided to adopt a roundabout offensive strategy and attack Henan from the western side of Shaanxi. Genghis Khan ordered the general Miki Hebaldu to lead 10,000 Mongol cavalry, pass through the Western Xia Kingdom, raid Jingzhao, and bloody the ancient Roman city of China, and then wave his army south to attack Tongguan.

This Xiongguan, built in the Later Han Dynasty, borders Huashan Mountain in the west, the Yellow River in the north, and Taolin in the east, and is located at the confluence of the Yellow River and Weishui, which is an important town to block the Mongolian army from entering Henan. Because he couldn't capture Tongguan, Sanmu Heba had to continue south along the side of Huashan and came to the foot of Songshan Mountain, and finally captured Ruzhou south of Luoyang. Through the Loess Plateau, Miki Hebaldu led his cavalry across Henan and reached Bianjing, the new capital of the Jin Kingdom.

However, the king of Jin deployed tens of thousands of troops around Bianjing, and Miki Heba could not take it for a long time, so he had to withdraw his troops and pass over the frozen Yellow River before withdrawing his army to Mongolia. At this time, the 10,000 Mongolian cavalry led by the general Tuolun also conquered Zhending, flooded Dongping with the Yellow River, and ransacked Dongping. There are also 10,000 cavalry led by Shi Tianni and others, who took the east road and captured Pingzhou, but encountered resistance in Guangning, and attacked for many days before capturing Guangning City.

In just a few months, the Mongol cavalry swept almost all over the Central Plains with a devastating force, capturing 862 cities of the Jin Dynasty, and the north of the Yellow River has roughly become the world of the Mongols. Genghis Khan, after his great victory in the fourth assault on Jin, drove the forces of the Jin court to the south bank of the Yellow River, and he was content with this, and paid little attention to the war in the Central Plains.

He never launched a serious offensive to force the Jin king, and even north of the Yellow River, with the exception of the Mongol army's firm control of the Central Capital, he saw the Central Plains he occupied almost exclusively as an open field, an area for the troops he left behind to plunder. Genghis Khan's view was partly due to the fact that the Mongols at the time did not yet understand the way of urban life.

During this time, every time the Mongol army captured a city, it then sacked it, then abandoned it and left it. As soon as the Mongol army left, the Jin emperor sent troops to recover the cities, and by the following year, everything was starting from scratch.

In this way, the two sides attacked, recovered, recovered, and captured, and ravaged the Central Plains like a see-saw, causing the people to cry and cry hunger and starve all over the land, and the Great Plain of North China, which was originally fertile for thousands of miles, became a barren and barren land.

Genghis Khan had realized that the Jin Dynasty was no longer a big problem, so he shifted his main energy to the west, and the vast battlefields of the Central Plains were borne by a loyal general he chose, that is, the famous General Mu Huali. Mu Huali is called by Genghis Khan as a close minister with a chariot and an arm.

Mu Huali's prestige has long been thunderous in the Mongolian steppe, he followed Genghis Khan's bloody battle, from the Mongolian steppe to the Central Plains battlefield, leading an army alone, presiding over all aspects, assisting the Great Khan, strategizing, all able to win the battle, and the strategy is meritorious, his position and role have become Genghis Khan's deputy marshal and assistant.

Now that Genghis Khan is running the West and embarking on a journey, he wants to preside over the overall situation of the war with the Jin State and continue to maintain the dominance of Mongolia in the Central Plains, and Mu Huali is naturally the most suitable person.

Employing people without suspicion and suspicion is the most clever thing about Genghis Khan's employment. Over the years, he has treated his subordinates, once he sees the right person, he always trusts him absolutely, boldly lets go, only hands over tasks, and does not interfere with specific actions, so that he can be in place in time and have the right to do so, which allows him to fully display his talents. In the treatment of Mu Huali's hands-off appointment, this point is fully reflected.
