It turned out that Temujin received a report during the attack on the Kingdom of Jin, and knew that Zahe would dare not rebel, so he immediately returned to the army.

At this time, Zaheda, along with his four sons and five grandsons, led an army to attack the Mongol camp. Fortunately, the Mongols built a city on the side of the Buerhan Mountain, and under the command of Yelu Chucai and Shen Bai, most of the herdsmen, the elderly, the weak, women and children hid in the city in time. At the same time, orders were given to the old men and children who could use their weapons, as well as the able-bodied women, all to go up to the city to defend it.

The men and horses who dared to do so were all cavalry, and there were no siege equipment, and the city walls were less than two zhang high on average, and there was nothing to be done about them. You can only circle around the city wall and shoot arrows at the city. But the walls of the city were filled with battlements to hold back arrows, and the defenders of the city returned fire with bows and arrows, so that Zaheda, who had not been able to attack the city for seven or eight days, could not enter the city.

At this time, Temujin's vanguard arrived, and the 5,000 cavalry led by Jebe and Subutai arrived, and the two sides fought a great battle under the city.

There are not many people who dare not to rebel with Zhahhe, there are only more than 6,000 people in total, and the Hara Khitan army of Qu Qulu is still west of the Altan Mountain, thousands of miles away. Although the Mongolian army came from afar, but in order to rescue their relatives, everyone fought bravely, plus Jebe and Subutai were fierce generals, and they rushed violently, and Zaheda dared to defeat the Mongolian army, and there were less than two thousand men and horses left. Even Zha He dared to be hit by three arrows and almost died. Of his four sons, two were killed in battle, one was captured, and only one escaped. The five grandsons were even more dead and two were captured, and none of them ran away.

Zahe dared to be over sixty years old at this time, and he was seriously injured, and he was hurt by the casualties of his children and grandchildren, so he was naturally angry and anxious in his heart, and when he ran to the vicinity of the Hanerhan River, he finally couldn't support it, and he died with a whimper. His only son was also killed by his men, and he took the heads of their father and son to surrender to Temujin.

By the time Temujin led his army back to the camp, the rebellion of Zahedano had been largely quelled. However, this rebellion did not cause many casualties, and it was entirely the Mongol walls that played a constructive role, so Tie Zhenzhen praised Yelu Chucai, who advocated the construction of the city, and many of those who had previously opposed the construction of the city also changed their attitude. I also admired Yelu Chucai even more. At the same time, they also fully supported Allah Zhang to raise the city wall to three zhang.

Although the rebellion of Zaheda was put down by the scriptures, it was still a major trouble for the prince of Naiban to bow out of the law. But Temujin was also caught in a deep dilemma. For several days, the generals were gathered to discuss, but no result was discussed.

It is said that Temujin should immediately send a large army to meet Qu Qu Lu's Hara Khitan army, because Qu Qu Lu was the prince of Naiban in the past, and the only heir to the throne of Naiban Khan, although he was rough and impatient, he still had great power among Naiman. If left unchecked, I am afraid that the entire place west of Hangai Mountain will be recaptured by Qu Zhulu. Therefore, this time it is not only necessary to defeat Qu Qu Lu, but it is also best to destroy the Hara Khitan and completely eradicate the troubles.

However, Naiman is in the westernmost part of the desert, starting from Buerhan Mountain, and it will take at least a month to march to Altan Mountain, where Naiman is stationed, and Hara Khitan is still west of Naiman, and the vast expanse of the radiating plain is said to be not under the Mongolian steppe, so it will take at least half a year to go back and forth. Now the Mongolian Yijing and the Jin State Yijing have completely torn their faces, once the Mongol army goes to meet Qu Zhulu's army, the Jin State knows that in the future, it will definitely send troops to invade the steppe, so then Temujin will not even have time to return to the army.

Therefore, the generals such as Zhu'er Tuba, Jebe, Subutai, and Kublai asked for orders one after another, asking them to lead a group of men and horses to meet Qu Chulu, while Temujin continued to sit in the city of Buerhan Mountain, preparing to meet the attack of the Jin State.

But letting a general attack with a small number of men and horses is not enough to destroy the entire Hara Khitan, at most it can only repel Qu Qu Lu, and after the Mongol army retreats, Qu Qu Lu can make a comeback. If you want to completely destroy a big country like Hara-Khitan, Mongolia must dispatch most of its men, and although such a huge force is its own old subordinates, Temujin still does not feel at ease to hand it over to that one person to command, and it is still in his own hands, so he can rest assured.

Just more than ten days later, news came from the west of the steppe that Qu Zhulu led an army of 100,000 Hara Khitan to attack Altan Mountain. Obviously, at this time, Yijing could no longer hesitate, and Temujin listened to Yelu Chucai's advice, and first sent Jebe and Subutai to lead 20,000 Mongol troops to Altan Mountain to resist the enemy. Then he sent people to inquire about the movements of the Jin Kingdom and the Southern Song Dynasty, and then made a decision.

After waiting for more than two months, Jebe and Subutai's men and horses arrived at Altan Mountain and immediately stabilized the battle. Facing an army five times larger than himself, Jebe and Subutai really ordered the Mongol army to be divided into ten groups, attacked separately, and launched a fierce attack on the Hara Khitan army from all sides. Qu Zhulu was also at a loss for a while, taking care of one and losing the other, and he didn't know how many men and horses the Mongolian army sent, but the two sides fought six battles in a row, and the Mongolian army won five victories and one defeat, killing more than 20,000 people of the Hara Khitan army.

Qu Zhulu led the Hara Khitan army to attack Mongolia this time, which was already unpopular, and the soldiers of Hara Khitan were simply unwilling to fight this kind of meaningless battle, and this time it was even more deviant and unstable. Qu Qulu had no choice but to order the withdrawal of the army.

And Jebe and Subutai divided their troops into two routes, Subutai led 10,000 horses to follow the Hara Khitan army to pursue, and Jebe led 10,000 horses, with one person and three horses in rotation, and hurried to the front of the Hara Khitan army to block the robbery. After three days and three nights of pursuit, they finally blocked the front and rear near the Erqisi River and caught up with the army of Hara Khitan.

Jebe first gave the Hara Khitan army a head-on blow in front, at this time the Hara Khitan army still had nearly 80,000 horses, but Qu Zhulu never dreamed that the Mongol army would go around to his front, so he had to rush to meet the battle, although the Hara Khitan army was numerous, but the army had no fighting spirit, so it and the 10,000 Mongol army only fought a close match.

At this moment, Subutai led the men and horses to arrive from behind, the Mongolian army was flanked in front and back, and the Hara Khitan army was immediately defeated, and was defeated and defeated, and more than 20,000 people were killed on the spot, and nearly 8,000 people were forced into the Erqisi River and drowned. Qu Zhulu fled back to Hara Khitan with only more than 30,000 horses, and the remaining nearly 20,000 were all captured by the Mongol army. After the end of the battle, the captured Harakhitan soldiers were slaughtered by the Mongol army, and their corpses were piled up on the banks of the Erqisi River, as high as a hill.

Temujin was also very happy to receive the report of Jebe and Subutai, and immediately ordered Jebe and Subutai to be stationed by the Erqisi River and wait for his next order. The envoys of the Southern Song Dynasty also arrived in Mongolia and told Temujin that the Jin State was about to invade the south, and demanded that Temujin fulfill the promise of the alliance and send troops from the north to contain the Jin forces. The Mongol spies also returned to the steppe, confirming that what the envoys of the Great Song Dynasty said was not a lie, and that the Jin State was indeed about to make a major expedition south.

Temujin couldn't help but be overjoyed, this was a once-in-a-lifetime opportunity, taking advantage of the current Jin and Song wars, it was just right to send a large army to the west, pacify the Hara Khitan, and remove the future trouble of Qu Qulu. As for the Song and Jin ties, let them fight to lose both.

But Yelu Chucai spoke at this time, reminding Temujin not to forget the Song-Mongolian alliance, now the relationship between Song and Mongolia is a bitter relationship, if you sit back and watch the Jin State destroy or hit the Southern Song Dynasty hard, then the next one will be Mongolia's turn. With the strength of the Mongol side, it was simply not enough to fight the Jin State alone.

When Temujin heard this, he suddenly realized, and he was amazed that Yelu Chucai had seen it comprehensively. Then he gathered the generals and ministers, discussed for three days, and finally made a final decision.

Temujin personally led an army of 80,000 to conquer Hara-Khitan, of which 50,000 were Mongol cavalry, including 20,000 vanguard troops brought by Jebe and Subutai. The other 30,000 were miscellaneous infantry troops of other tribes. The generals who accompanied Temujin on the expedition were Borshu, Chilaowen, Kublai, and Zhu'er, as well as Temujin's three younger brothers, Hejuer, Temuge, and Belgutai, and his four sons, Jochi, Chagatai, Ogedai, and Tulei. And Yelu Chucai as a military advisor. In addition, because Temujin Kedun Gulbesi was originally the favorite concubine of Naiban Tayang Khan, and was also very influential among the Naiban tribe, he also went on the expedition with the Mongol army this time.

The power to fight against the Jin State was all granted to the general Mu Huali, and all matters related to the war against the Jin State could be handled cheaply and by making their own decisions. And according to the official system of the Central Plains, Mu Huali was crowned as the prince, the king, and given the golden seal, with Bolhu as the deputy general, and the Khitan generals Yelu Ahai and Yelu Bald Flower were also used under Mu Huali's subordinates. He led an army of 30,000, including 10,000 Mongolian cavalry, 8,000 Khitan soldiers, and 12,000 miscellaneous infantry troops, and gave Mu Huali a nine-plain white banner, telling the generals: Mu Huali planted the flag here, and the order issued was equivalent to that of me personally.

In the end, he left the generals to lead 30,000 horses, including 20,000 Mongolian cavalry and 10,000 miscellaneous infantry troops, to stay in the camp.

After the assignment was completed, Temujin did not hide it from the envoys of the Song Dynasty, and Yelu Chucai came forward to convey that the Mongol troops were assigned to the Song Dynasty envoys, and repeatedly emphasized the difficulties that Mongolia was currently facing, and asked the envoys to explain clearly to the Great Song Dynasty monarchs and ministers after returning to China, and promised that once they defeated the Hara Khitan, they would immediately withdraw their troops and attack the Jin State.

Of course, the envoys of the Song Dynasty could not express any opinions on the internal affairs of Mongolia, but only said that after returning to China, they would definitely convey the truth to the imperial court, and Yelu Chucai wrote a letter and handed it over to the envoys to take back.

Subsequently, the Mongol armies each drew their own camps and went their separate ways.
