After getting his father's approval, Li Shimin rushed to the Weibei military camp non-stop to prepare soldiers, horses, ordnance, baggage, and grain for the upcoming war.

Li Shimin, who has been on the battlefield for a long time, knows that Song Jingang is actually not his opponent in this northward battle. What he was about to really face was the Turkic cavalry sent by Chuluo Khan to assist Song Jingang, who was known as the most elite in the world.

To this end, he specially trained a team of ironclad cavalry who dared to serve the death, named the "Xuanjia Army".

The soldiers of the Xuanjia Army were all dressed in black and armor, and even the mounts were all black and shiny black horses. The soldiers wore long knives forged from stainless steel to imitate the Han Dynasty sword, and carried black-painted boxwood bows and buffalo skin quivers, which were filled with a hundred carved arrows, and even the arrow clusters were forged from black iron that could shoot through three layers of heavy armor. It is uniformly equipped with high-bridge saddles and stirrups for cavalry......

In short, Datang's most advanced equipment is used in this team.

If the sophistication of the equipment is commendable, what is even more commendable is the quality of the elite soldiers.

Li Shimin led a carefully selected 5,000 warriors into Longshan, and finally only 3,000 warriors were selected to serve as the Xuanjia Army.

Every warrior has to go through layers of levels. Among these 3,000 warriors, one was selected at random, not only with strong physique and excellent martial arts, but also extremely strong psychological quality.

Li Shimin set an iron discipline for them, and they will not hesitate to enforce the orders and prohibitions. Even if you fight to the last man, you won't back down.

They can kill the enemy with crossbow arrows from afar, and use long knives at close range, coming and going like the wind, and they are only controlled by Li Shimin alone.

By the time the military department and the household department had prepared all kinds of military supplies, it was already the middle of winter.

The land of Guanzhong has snowed several times, and the Longmen ferry of the Yellow River has been covered with a thick layer of ice. Li Shimin decided to lead a large army to cross the Yellow River on solid ice, so the 30,000-strong army was ordered to assemble at the Longmen Ferry.

Li Yuan knew that his son was going desperately, and he didn't know if this was the last meeting of the father and son, so he was uneasy.

He personally rushed to the Longmen Ferry, where he cooked wine and candied for his son.

Before leaving, Li Yuan said to Li Shimin with emotion: "Son! Whenever I have a problem in Datang, you always stand up! If my father can be ten years younger, he will definitely go to the battlefield with you again! ”

Li Shimin naturally said goodbye, then bid farewell to his father, got on the horse and led the army away.

Li Yuan looked at his son's back reluctantly, and he watched the 30,000-strong army gradually move away, until he disappeared into the snowy curtain, and then returned to the palace under the reminder of the attendant.

When he first arrived in Hedong, Li Shimin stationed the handsome tent at the foot of Baibi Ridge, and he issued the first military order in the mountain camp - the whole army is waiting for the order, and there are those who go out to fight without authorization, and the three tribes are destroyed!

On the other hand, he sent a number of henchmen to contact many of the old troops who had been forced to surrender when the Turkic army was overwhelmed.

He played a big game of chess, and the whole Hedong was a big chessboard. His first move was to cut off the enemy's food routes.

After more than a month of operation, the enemy's food and grass were obviously tight. The enemy generals Chi Jingde and Xun Xiangzhu couldn't bear it anymore and took the initiative to come to the Tang army's camp to challenge.

Li Shimin sent the Xuanjia Army out to respond to the battle, and the enemy army was defeated and fled.

Seeing the enemy fleeing, the generals wanted to take advantage of the victory to pursue, but were ordered by Li Shimin to return to the camp.

After that, after more than five months of confrontation, the Tang army basically did one thing, robbing grain and cutting off the enemy's grain route.

There was a shortage of food and grass in the enemy's camp, and the horses were getting weaker and weaker, and the soldiers could not take the next meal. Many of the soldiers had no intention of fighting at all, and went hunting in the mountains. The morale of the enemy army fell to its lowest point since the war.

In the blink of an eye, in the early spring, after the ice and snow melted, bursts of sand storms blew on the field. On the grassland, the pasture grass has not grown, and the grain of the Central Plains has only been planted. This is the time when the green and yellow are not connected.

Li Shimin knew very well that the fighter plane he had been waiting for for had finally arrived.

Li Shimin led the Xuanjia Army to charge at the front line, and the enemy troops with thin horses and tired soldiers began to retreat on the whole line without resisting a few times.

Li Shimin led the army to chase and fight all the way, not giving them a moment of respite. The Tang army was able to kill, and within one day, it fought for hundreds of miles.

As the commander-in-chief, Li Shimin was blood-stained and sweaty, and the war horse under his crotch was also sweaty on his neck and chest, and he didn't even realize it.

Seeing this scene, his uncle Dou Liang persuaded him to rest his feet and pursue again, but Li Shimin rejected him, he thought that the fighter plane was rare, and he must completely defeat the enemy in one go.

When the Tang army pursued to the Bird Mouse Valley, the tens of thousands of Tang troops led by Pei Lin had turned into white bones at this time, and Song Jingang lined up here to resist the enemy.

He thought that Tang Jun would be terrified when he saw the bones of his compatriots.

It's a pity that he miscalculated. Because the Xuanjia Army is an army of iron will.

Under the leadership of Li Shimin, the enemy's formation was instantly crushed. The morale of the Tang army was greatly boosted, and the shouts shook the heavens and the earth.

In the Valley of the Birds, the two sides fought eight fierce battles in one day, and most of Song Jingang's main force was annihilated.

Li Shimin knew that the enemy's general trend had gone, so he dismounted and rested with his soldiers in the Bird Mouse Valley for a few hours.

By the way, I paid tribute to the dead souls.

On the second day, the Tang army marched again and came to the foot of Jiexiu City.

Song Jingang opened a long snake formation under the city, trying to fight against the water.

Li Shimin was familiar with military books and knew the method of cracking this formation, so he quickly arranged it, and it only took a few hours to annihilate all the enemy troops!

Song Jingang was already frightened and lost his soul, and he fled back to Jinyang City with only a few followers. There were not many defenders in the city, and it was difficult to resist in the face of the Tang Dynasty army.

One dark night, Song Jingang and Liu Wuzhou led a few cronies to secretly flee north from the north gate of Jinyang City, and their destination was Dingxiang City at the foot of Yin Mountain, where Luo Khan's Khan court was located.
