King Wei Wanyan Yongji was terrified! He immediately ordered: Tungis was removed from the line of fire, and Wanyan Chengyu was replaced with Wanyan Chengyu to preside over the front-line military. Changing generals before war is a taboo for soldiers, and it is especially unforgivable that Wanyan Yongji will not look at people at all! Tong Ji Sizhong failed, but he was on the front line from beginning to end, fighting with the Mongols for every inch of land. What about the newly appointed Wan Yan Chengyu? He's too smart.

Shocked by the stormy onslaught of the Mongol army, Wanyan Chengyu decided that he would not be able to resist head-on no matter what. To be precise, he couldn't resist in the offensive and defensive system of military common sense, so he used an uncommon one: he took the initiative to give up the three states of Huan, Chang, and Fu, and retreated directly to Yehuling in Xuande Prefecture!

This is foolish! The three prefectures of Huan, Chang and Fu are the fortresses of the northern Xinjiang of the Jin Kingdom for many years, the city walls are strong, the grain and grass are sufficient, and if used properly, it is enough to delay the speed of the Mongolian iron cavalry! Even if it can't really be blocked, it will cause a large number of Mongol warriors to be attritional. Take 10,000 steps back and say: If the Mongol army dares to cross these three states and go straight to the capital of Jin, then behind Genghis Khan, these three fortresses will become a hidden danger for the Mongols! It will be like the Dingzhou Array attached to the Liao army when the Empress Dowager Xiao of the Liao State invaded the Yuanyuan, so that the Khitans did not dare to fight to the death with the Song army! Furthermore, if Wanyan Chengyu reasonably distributes the huge 400,000 troops in his hands, if each half of them defends Sanzhou and Yehuling respectively, a more effective stepped defense will be formed, allowing the Mongols to shed the most blood possible, so that the Zhongdu will be safe... He didn't expect any of this!

In fact, since he ordered the whole army to retreat to Yehuling, the overall strength of the Jin Kingdom and even the national fortunes have dropped by a notch! The rich and solid livelihood and grain of the three prefectures of Huan, Chang and Fu are actually nothing if they fall into the mouth of the Mongols, the important thing is the pastoral supervisor of Huanzhou! It was the most important military horse farm in the Golden Country! There were millions of fine warhorses inside, and they were the most important weapons of the time, and nothing could compare to them! What happened after the Northern Song Dynasty lost Lingzhou, what happened to the Jin Kingdom when it lost Huanzhou! The dignified Jin Kingdom, the Saibei nation that also started with bow horses, will actually worry about war horses from now on!

Genghis Khan, who has a super keen sense of war, will certainly not let go of the fat that comes to his mouth! The Mongol army swept like locusts through the three northern states of the Jin Kingdom. Everywhere they passed, not a single hair was left for the Jurchens!

The rest is Wanyan Chengyu who retreated into Wild Fox Ridge! Yehuling, the key pass of the ancient Great Wall. The momentum is very high. The geese flew over here and fell in the wind. It is said that the highest point of this ridge is only 18 miles from the sky. It is a dangerous pass that can be opened by one husband and ten thousand people. Coupled with the fact that Wanyan Chengyu's troops were far superior to the Mongol army, the Battle of Yehuling became the first turning point in the Battle of Jinmeng!

A few days ago, because the troops were evenly distributed in the 600-li long wall, the guide was broken by the Mongol army and drove straight in. A few days later. Wanyan Chengyu did the same in Yehu Ridge, and once again spread his troops evenly on this steep mountain...

In the face of a Jurchen brain as stubborn and stiff as elm, the strategy of a generation of Tianjiao is almost perfect. Once again, the point of attack was set at the strongest point of the Jin Army - the big tent of the Chinese army with the commander Yan Chengyu!

The reason for this. It's completely aimed at Wanyan Chengyu's weakness! This Jurchen is cowardly, and giving up the three states and a million military horses is not so much stupid as cowardice. He didn't dare to face the threat head-on!

Seeing this, Genghis Khan was equivalent to grasping the lifeline of the Jin army, and all that remained was the battlefield table, and this was the unparalleled place where the Mongol warriors roamed the world!

Wanyan Chengyu's big tent of the Chinese army is set up in the mouth of the badger. One of the four masters, the Mongolian god of war Mu Huali, please fight! The most warlike Mongol chose the bloodiest and most monotonous tactics. Nothing else but a strong attack! Only this can ensure victory! Mu Huali led the Mongolian army into Yehuling! The mountains are steep, the ravines are crisscrossed, and the vegetation is messy, and it is not a place to ride a horse at all. The attacking Mongol soldiers then dismounted and fought on foot, attacking and killing the Chinese army with Yan Chengyu...

Until this time. It was only after Yan Chengyu realized that he had made another fatal mistake! Mountains are better than flats! Between the 600-mile long wall, the Jin army can support the target as far as the eye can see at any time. But in the mountains, he couldn't mobilize an army to command the battle!

In other words: Mu Huali concentrated the elite to attack him, and he could only rely on a few poor personal guards and limited troops to hold on. The so-called 450,000 troops did not play a role at all!

This is something that Yan Chengyu can't bear! This man jumped up and fled, not giving the Mongols a chance to entangle at all, and fled down the Wild Fox Ridge with a smoke! It is said that behind him there was a mountain of corpses and a sea of blood, and the screams and wails were loud. He didn't have a single wound on his body...

As if he had abandoned Sanzhou a few days ago, he abandoned Yehuling and fled south with the troops that could be mobilized around him! Behind him. Mu Huali chased after him. His task is to keep an eye on this Wanyan Chengyu, and the huge Jin army troops in Yehuling will naturally have Genghis Khan to deal with it. In the process, the Mongols showed a frightening group strategy! They did not rigidly implement the pre-war policy. When the battle progressed to the point where Muhuali pursued and Genghis Khan intercepted, the two made huge concessions at the same time. Mu Huali let Wanyan Chengyu escape a hundred miles away to catch up, and Genghis Khan slaughtered in Yehuling, but left a lot of gaps, allowing the Jin soldiers to take the opportunity to escape...

Of course, you can also say that because Yan Chengyu ran fast enough, Mu Huali lost time by looking for a horse to chase again. You can also say that because of the changeable terrain of Yehuling, the Mongolian army is fighting in the guest territory, and it is impossible to block the whole mountain... But then it was different!

The distance of more than 40 kilometers has become the death line of the Jin army. They ran desperately, and the Mongols pursued them in a measured manner. In the process of escaping, people kept falling, and the last bit of vitality was squeezed out by the Mongols. Until this time, more than 40 kilometers were completed. Huihe Fort at the junction of Xuande Prefecture and Datong Mansion has arrived!

Mu Huali has surrounded Wanyan Chengyu here. But he instantly let go of the encirclement and let all the fleeing Jin troops gather at Huihe Fort! Genghis Khan then arrived, and 100,000 Mongol troops surrounded more than 300,000 Jin troops. The Battle of Huihe Fort has officially begun!

During this period, the war situation changed, and in ancient times, there were no means of communication such as telephones and telegrams, so one could only rely on the tacit understanding between generals and commanders on the battlefield. From the assault on Yehuling to the formation of the encirclement of Huihe Fort, the Mongol army did not make any mistakes. They drove the Jin army out of Yehuling, and after the victory or defeat was changed, they drove away, encircled, chased, gave way, surrounded... Every step is in place!

By the time they arrived at Huihe Fort, the Mongols had completed a game-shaking trick, and they had actually compressed the entire Jin army into a small area! Looking at the overall situation, this is really an unparalleled control force, and it is also a chilling group strategy!

After that, Huihe Fort was a huge slaughterhouse. The Mongols kept attacking. Little by little, it eats away at the little bit of pitiful fighting spirit that the Jin Army has left! When the fighting spirit disappeared and the desire to survive was insufficient, the Mongol army began a decisive battle! Huhe Fort instantly became a hell, a meat churn, a Shura field... I can't overstate it!

Because except for Yan Chengyu who successfully escaped into Xuande Mansion again, the Jin army who participated in the war this time basically died here! In the battle of Wushabao-Yehuling-Huihebao, the first contest with Mongolia, the Jin State lost all its central mobile forces, forming a power vacuum in the Central Plains. The Mongols galloped on horseback, coming and going at will, without any hindrance...

On September 12, Mahu Man invaded Xuzhou on Tongchuanfu Road.

On the 26th, Luo Shichuan was killed by his subordinate Hu Yougong. It was only after three years of suffering that he was completely pacified. Everyone celebrates.

In September, the Mongol army attacked the pre-war target - Daxingfu, the capital of Jin! On this road, only one last fortress remains: the Great Wall Juyong Pass! This is the famous Guguan City along the Great Wall of Jingbei, and the terrain is extremely dangerous. Together with Bauhinia Pass and Reverse Horse Pass, it is called the inner three passes.

At the last pass, the Mongol army attached great importance to it and sent Jebe to attack. didn't wait for the start of the fight, with a new situation, Jin Guo actually had an army to take the initiative to challenge?

He came from Xijing Datong Mansion to escape from the Shishi Liezhong (also called Hu Shahu), he led 7,000 elite horsemen to come day and night to help the war... Then he took advantage of the night and ran back day and night... This man came in too haste. I don't know what the battle situation is, but I only know that this is the situation when I get to the scene!

This man fled with a few guards at night, and the Mongol army attacked at dawn, and the 7,000 elite troops were annihilated. By this time, he had already hurried to Ulju. Look around: no people, no money, no food? Su Shilie ordered that the treasury of Ulju Mansion be whitewashed first, especially the treasury silver, as his travel expenses. Then go and grab the official horse to maintain the speed. Both. If you kill some civilians again, you will have some blood on your body, and it will look like you have come back from the front line. To be clear: in the process. He also dragged the Laishui County Order out and beat him to death on the street, probably hindering his good deeds?

In this way, Master Su Shilie finally took the Bauhinia Pass and fled into the capital of the Jin Kingdom!

On the other side, in the direction of Juyong Pass, the Mongol army began a strong attack! Jebel is in battle, and it is difficult to be sharp! But the worst thing is that this time it is Juyong Pass, and you can't fight on horseback like you can on the prairie. So he had to start over all over again... What's even worse is that there are still cannons on Juyong's close!

At this time, the cannon was still a giant trebuchet, and it would be more than 40 years before the world's first weapon powered by the burning of black powder appeared in the Southern Song army. But that didn't stop Jebel from being smashed all over the head by the big rocks that fell from above. He was angry in his heart, and evil was born to the side of his guts, and he rushed forward as fast as he could, reducing the number of bags on his head. He then took a keen interest in these cannons and introduced them to his Great Khan... The Mongol army crisscrossed the Eurasian continent, relying not only on blind war horses, bows and arrows, long knives, but also cannons in many cases, to be precise, the credit of the "return cannon"!

Wanyan Fushou abandoned the pass and fled, and Juyong Pass fell! Daxing Mansion, the capital of Jin, was exposed in front of the Mongol army! After more than 200 years of operation by Liaojin and Jinjin, it has become the largest military and political center in northern China at that time. Zhongdu is divided into two cities, the outer city has a circumference of 5,328 zhang (about 35 miles today), and there are sub-cities with a circumference of 3 miles around it. The upper floor of the city, the moat, the arsenal granary, and the inner and outer cities are connected. It is an important town with three-dimensional and ladder defense!

King Wei Wanyan Yongji ordered martial law in the whole city! No man is allowed to enter or leave the gates! Genghis Khan's army approached the middle capital. Wanyan Yongji immediately panicked, and planned to be protected by 5,000 elites and flee south to Kaifeng Mansion in Nanjing. But no one wanted to, not even his cronies. So the battle to defend the capital began!

The two sides engaged in a brutal war of attrition inside and outside the city walls, and the Mongol army did not take advantage of it. Taking Zhongxingfu, the capital of Western Xia, as an example, the Mongol army fought each other for several months, and even the Yellow River burst its embankment, but to no avail. It is conceivable that the storming of the capital of Jin is not very realistic for the Mongol army at this stage...

Guo Baoyu, who surrendered, was introduced to Genghis Khan by Mu Huali and asked for a strategy for taking the Central Plains. Guo Baoyu said, "The Jin country is powerful and difficult to obtain. The southwestern Zhufan, brave and available, should be taken first. In order to "Tujin" and said, "At the beginning of the founding of the country, it is advisable to issue a new decree", so under Guo Baoyu's construction, Genghis Khan promulgated five new decrees: 1. The army shall not be killed in vain; 2. The prison shall be punished with death only for serious crimes, and the rest of the miscellaneous offenders shall be punished by flogging; 3 Mongolians, Semu people every Ding up an army, Han people have four acres of land, people three Ding sign an army, more than 15 years old, 60 for the old, station households and military households the same; 4. The land of the people is limited to 1 hectare; 5. If the monks are not beneficial to the country and harmful to the people, they are forbidden.

On October 26, due to the war between Jin and Mongolia, the Southern Song Dynasty ordered the front lines of the border with the Jin State: Jianghuai, Jinghu, and Sichuan to repair the border preparations to prevent the Jin State from robbing. But at that time, the Jiading Peace Conference had just been signed, and the generals on the front line of the Southern Song Dynasty did not care, thinking that there would be no war between the Song and Jin. Only in Zhao Fang, the capital of Jinghu North Road, Jiangling Mansion, knew that the Jin people were forced to Mongolia in the north, and they were bound to "lose in the north and gain in the south", so they took precautions day and night, and added and repaired the three seas and eight confines to strengthen the shì. Build forts and increase troops on the east and west mountains of Jingmen to stop the enemy from rushing. At the same time, the local tyrant Meng Zongzheng and Meng Heng father and son were promoted.

Faced with the high city and deep middle capital, Genghis Khan fought very shrewdly and knew how to fundamentally weaken the other side. He himself tightly surrounded the central capital city and personally shocked the monarchs and ministers of the Jin State. He sent his three sons, Jochi, Chagatai, and Ogedai, to attack the rest of the state cities. Because not every Jinguo city is as strong as the middle capital city!

This month, the outer city of Zhongdu was breached, and the inner city was more defended, and every sign indicated that the Mongol army could not do much! Genghis Khan personally interrogated the captives "how many Jin troops were in the city" and replied "200,000"

However, at this time, King Wei Wanyan Yongji couldn't stand it first, and he sent an envoy to sue for peace. I am willing to sacrifice the princess and Genghis Khan like the Western Xia, and as for the vassal, I will never give in...

Genghis Khan sneered: What is the urgency of harmony? The Mongol army has come here, isn't it rewarded? He offered to ask for 30,000 camels and 50,000 cattle and sheep as military supplies! (To be continued......)
