"This is Lake Behail!" In the barracks, Zhao Chen, Qu Duan, Li Xianzhong and others were together, and Qu Duan pointed to the map at this moment.

Lake Behail was later called Lake Baikal, and in this era it was called Lake Behail!

"Every autumn, a large number of Mongolians gather here! Many tribes perform autumn festivals here, thanks to the blessing of the immortals! It's their custom and tradition! The military intelligence department has been exploring the grasslands for several years, and it has been the case for all years, and almost half of the grassland tribes will go here! The military headquarters is ready to use 400,000 cavalry to encircle and annihilate the Mongols here! It can be said that this is another national battle! All the cavalry in the whole north is going to be dispatched! Qu Duan said.

"400,000 cavalrymen from four armies, and they need to cooperate well with each other! The Government Council and the Military Department have decided to set up a joint cavalry command in the north to direct this operation and deploy all armies, with Yue Fei as the chief commander, Li Xianzhong, Liu Qi, and Han Shizhong as the deputy commanders, and you will be responsible for the specific war! I'm here to see how the armaments are going to be! Over the years, half of the soldiers in the army have been recruits, and I don't know if they can participate in this combat mission. Zhao Chen said.

"Your Majesty, rest assured, we will never let you down!" Li Xianzhong said.

"Very good, today I will rest for the night, and tomorrow morning I will inspect the army!" Zhao Chen said.

Early the next morning, when the sky was slightly bright, more than 100,000 troops had already gathered.

With Zhao Chen's order, the sound of ten thousand horses galloping sounded, and all the cavalry galloped towards the north!

The soldiers' riding skills are extremely high! They have been training hard every day since they entered the army!

Zhao Chen first watched the basic riding skills of the soldiers, and in the afternoon, the large-scale exercise began!

The army of more than 100,000 was divided into two parts, and they fought against each other on the vast grassland ahead!

The exercise lasted for ten days, and during these ten days, Zhao Chen has been following the army, he has been observing, and the staff officers of the military department have also been observing, and at the same time judging the combat effectiveness of the army!

"Your Majesty, although a large number of new recruits have joined the army, the combat effectiveness of our army has not decreased much! It is true that the recruits lack combat experience, but years of hard training are enough to make up for the lack of experience! Moreover, there are still a large number of veterans in our army as core personnel, and in the real war, veterans can fight with new recruits, so that the recruits can gradually mature in the war! These recruits are in need of a baptism of war! Qu Duan reported the judgment made by the staff officers of the general headquarters to Zhao Chen.

"As for this cavalry joint command, you have to be involved in it too! When this battle is over, you have to give me a report, and if there is another war in the future, a similar joint command may be established to command the operation in a unified manner! Zhao Chen said.

"The last general commands." Qu Duan nodded and said.

"I want to go to the north and see the Mongols." Zhao Chen thought about it and said again.

"This ...... Your Majesty, it is very dangerous to go north of Beijing. Qu Duan said.

"With so many armies here, what do I have to fear?" Zhao Chen said with a smile.

On the third day of the fourth lunar month, Zhao Chen and Li Xianzhong led 10,000 elite horsemen all the way to the north.

On April 13, Zhao Chen, Li Xianzhong and others came to Zhenzhou City!

Zhenzhou is located in the area of Ulaanbaatar, Mongolia, which belonged to the Khitan people in this era! The Great Song Dynasty inherited the land and population of the Liao Kingdom, and it stands to reason that this place also belongs to the Great Song Dynasty, but now this is actually an empty city! After the Great Song Dynasty unified the north, it did not have time to return here.

"Zhenzhou, the twenty-second year of the unification of the Liao State, built by the Empress Dowager Xiao, is the northwest of the Liao State to recruit the Yamen, and then Yelu Dashi went north, and also stayed here, this Zhenzhou also has a history of more than 200 years!" The army was on guard all around, and Zhao Chen and Li Xianzhong walked along the city wall of Zhenzhou City with more than ten guards.

The city wall here is very dilapidated, and the gate of Zhenzhou City in front of him has also fallen off, seeing such a scene, Zhao Chen can't help but sigh.

At this moment, more than 100 horsemen suddenly rushed out of the gate of Zhenzhou! These people are all dressed as standard Mongolians, and they didn't expect that there were still Mongolians in Zhenzhou City!

"Your Majesty, be careful!" Li Xianzhong was taken aback and said.

"Annihilate them all!" Zhao Chen sneered.

He rode his horse forward, and Li Xianzhong and the others hurriedly followed! Li Xianzhong shouted and rushed to the front, and the more than ten guards also rushed forward!

These dozen or so people had already met the Mongols, and almost as soon as they met them, their opponents immediately fell to the ground! They all had iron spears in their hands, and at this moment, the iron spears were flying, and none of the Mongols in front of them could block their moves! These more than ten people are all carefully selected warriors in the army, specially used to protect Zhao Chen's safety, and each of them is a master of the innate realm! After Zhao Chen unified the Great Song Dynasty, he was still in the military, and over the years, more and more martial arts masters have joined the army, eager to make contributions!

More than 100 Mongols didn't expect the Song army here to be so powerful, and after a while, they fled in all directions, and the surrounding Song army had already pressed up at this moment!

A quarter of an hour later, all the Mongols were subdued, and three Mongol nobles, dressed somewhat differently from the other Mongols, were escorted to Zhao Chen.

"Do you speak Chinese?" Zhao Chen said.

"I'll say." A handsome Mongolian young man who looked to be only in his twenties said in a strange tone.

"Excellent! Tell me why you're attacking us! Zhao Chen said.

"Look at your dress, you should be a person with a very high status among the Han people, if we catch you, we can use it in exchange for property!" The young man snorted coldly and said.

"Why do you Mongols go south to invade us every winter?" Zhao Chen said.

"You have money, so we're going to rob you! Isn't that a matter of course? Mongolian youth said.

"Sure enough, it's a scoundrel! I have endured you Mongolian scoundrels to the extreme! Come on, pull down, cut it! Zhao Chen sneered and said.

Immediately, the Song army dragged these Mongols down, but even when they were dying, these Mongols did not beg for mercy.

"Your Majesty, these Mongols have always been like this, and they have always felt that it was a matter of course to rob us." Li Xianzhong said.

"Pass the order, train the whole army carefully, and when autumn comes, we will completely eliminate these Mongolian bandits and completely eliminate the northern border trouble!" Zhao Chen said.

"The last will obey!" Li Xianzhong said immediately.

Zhao Chen, Li Xianzhong and others stayed here for more than ten days, observing the situation of the Mongols in various places, and then they returned south again, and Zhao Chen went to Yue Fei's army in Liaodong soon after to inspect Yue Fei's army.

From February 20 to the end of May Zhao Chen returned to Yanjing again, in three months, the important affairs of the Government Council and the 36 provinces were still sent to Zhao Chen's hands, but Zhao Chen did not make any instructions, and the imperial court was still operating normally, and there was no turmoil in the world! After years of development, the national system has been basically stable, which makes Zhao Chen very pleased.

******

The eighth month of the lunar calendar has arrived, and in the far north of Lake Baikal, Mongolian tribes are arriving one after another!

Lake Baikal is the largest freshwater lake in the world, and it is also the deepest freshwater lake, with 20% of the world's freshwater reserves, enough for the world's seven billion people for half a century! However, in later generations, it has nothing to do with China, and has long belonged to Russia.

During the Han Dynasty, it was called "Beihai" by the Chinese, and it was under the control of the Huns at that time!

When Su Wu sent the Xiongnu, it was in the Beihai area.

During the Eastern Han Dynasty and the Western Jin Dynasty, it was controlled by the Xianbei people, and it was also called Beihai at that time.

During the Tang Dynasty, it was controlled by the Turks, and until now, it has become a sacred place for the Mongols.

Autumn is crisp, and more and more Mongolian tribes are coming here!

By mid-August, the number of Mongols had exceeded 700,000, and there were more Mongols coming!

The entire area of Lake Baikal is much larger than that of the island of Taiwan, and its surroundings are large enough to accommodate more people.

Dozens of Mongolian tribal leaders, large and small, gathered together to discuss the invasion of the Great Song Dynasty in the south this winter! Speaking of joy, these tribal leaders couldn't help but laugh.

They didn't know that 400,000 Song troops had arrived one after another, and they had already launched a "hunting" operation against the Mongols! The hunt is the military code name of the Song army this time!

From mid-August, some Mongolian tribes and rangers on the periphery were attacked by the Song army, and then the Song army continued to push in!

The Mongols gradually felt that something was wrong!

On September 13, in the north, Yue Fei's 100,000 elite cavalry encountered dozens of Mongolian tribal coalition forces, and the war lasted for nearly a day.

On September 15, in the southwest, the armies of Han Shizhong and Li Xianzhong suddenly launched an attack on another group of Mongol tribal armies that were assembling here, and the Mongols were defeated again!

After nearly half a month, within a radius of hundreds of miles around Lake Baikal, the Song army and the Mongols fought more than ten major battles with a force of more than 100,000 troops!

The command system of the Song army is extremely efficient, and often after a war breaks out in a certain place, the surrounding Song army immediately comes to the rescue! And the Mongols fought separately from each tribe! With a modern military system against the loose and primitive combat system of the Mongols, the results of the war can be imagined! Moreover, the weapons of the Song army were far superior to those of the Mongols! The Song army was all delicate bows and crossbows, with barbed arrows, while many of the Mongols were still using bone arrowheads! The Song army was all light cavalry, but everyone wore iron helmets to protect their heads, and the Mongols did not have any armor at all! The 400,000 Song army were all young and strong soldiers who were good at riding and shooting, while the Mongols were both old and weak, women and children!

More than ten wars, the Mongols were completely defeated!

October is coming, and the "hunt" is still going on!

The Song army continued to encircle and suppress the army and division, and the sound of shouting and killing and bows and arrows was still heard on the grassland, and the corpses of the entire grassland were all over the field, and the corpses of the Mongols were everywhere!

This formidable northern barbarian tribe suffered a devastating blow, and afterwards the Song army counted the battlefield, and the corpses of the Mongols next to Lake Baikal exceeded 500,000! Many of them were old people and children, and during the war, these old people and children also fought back strongly, and the Song army did not show any mercy, and in the end, as long as the Mongols were besieged.

The first snow fell on the grassland, and the 400,000 Great Song cavalry still did not stop fighting, and they continued to hunt to the north and west......
