For Li Guangrui of Dingnan Army, his choice was narrower than that of the Zhe family.

There is nothing else. For the Zhe family, the fall of Taiyuan is just a shaking tiger across the mountain, and for the Dingnan Army, it is a bolt from the blue.

The existence of the Northern Han Dynasty gave the Central Plains a great solution to the Dingnan Army. However, they were not there in the attack last year, so naturally they felt uneasy.

Although Li Guangrui, the governor of Dingnan Army, was a martial artist, and he was not as smooth as his father's accident, he knew the situation.

As soon as he received the imperial edict, he immediately prepared to recruit 15,000 cavalrymen from various units, and then offered 2,000 war horses to Beijing, which was considered as an apology that had not been received last year, hoping to save some of the emperor's thoughts.

Pre-war preparations are essential, but walking is the same, and urgently needed.

That is to build a bridge for the Yellow River.

The 100,000 imperial camp headed north, and the current level of crossing the Yellow River is not enough to support it. Fortunately, the Yellow River is frozen now and it is time to build it, otherwise it will be too late to wait until summer.

Regarding this, Zhang Weiqing, who is in charge of the Yellow River affairs, wanted to curse her.

It is so tormenting to remove silt, build dams, and build bridges.

However, after the emperor allocated 100,000 ounces, he stopped complaining and started working calmly and seriously.

Li Jia held many imperial meetings. After many discussions, he finally set the time for the Northern Expedition to Youyun on the first day of April, which happened to be late spring.

The weather is neither hot nor hot, and it is suitable for large-scale marches.

For the Khitans, especially in the northeast, it is probably that the rain and snow had just melted and turned into a large amount of ice flood, and the grass below was exposed. After hungry for a winter war horse, they only ate two handfuls of grass, and it was far from the time to recover.

However, it seems that the Northern Expedition to the Northern Han Dynasty was too sharp last year. Since last year, more and more detailed spies from the north have become more and more, and the Sound of the Sound of the Sound System is simply too busy.

Unlike the south, the northern prefectures have not yet formed a land inspection, so there is naturally no household registration, which has omissions in preventing secret spies.

Some people have said that the accents of the Youyun area of ​​northerners are different from those of the Central Plains, and they are naturally very good at distinguishing.

However, the Khitans once captured a large number of civil and military officials, as well as the people who entered the north, had accents and other places, and they were simply unpredictable.

In this regard, the Sound and Sound Department focused all its main energy on Luoyang and the Hebei Prefecture generation to strictly screen those caravans from the north.

After all, there was no trade between the Khitan and the Tang Dynasty, and there was no market for discussion. There was no doubt that the caravan must have been smuggled.

After a set of seizures and reviews, you can always get a few detailed works.

The "sleepless law" and "confinement law" contributed by the emperor can be said to have contributed a lot of strength. Therefore, Wu Qing, commander of the Sound of the Sound of the Sound of the Sound, came to report.

"From October to the first month of last year, more than 500 Khitan Shuitao people were arrested, and many Khitan warriors were even openly in the caravan, which was simply too unfair to take the Sound Shooting Division seriously."

Wu Qing said angrily.

When Li Jia heard this, she couldn't help but smile.

The detailed work of this era, that is, the secret spies, can be as powerful as disguising as they are in the caravan and you can pass it by just stuffing some money. The method is as old-fashioned as ever, but it is quite practical. It is just not easy to use in the quite professional sound shooting department.

The infiltration of the Khitan by the Tang Dynasty was also a caravan. The rough management methods of the Khitans made the infiltration of the Shooting Division unfavorable. Many aristocratic officials who were captured thought of going home all the time, naturally would rather act as information providers.

"Just catch it!"

Li Jia shook her head. As the saying goes, in the face of all strength, any conspiracy is false.

Now the Tang army is strong, especially these people who fought south and north, and have won many victories, accumulated a lot of strength and arrogance.

The Tang army in the prosperous Tang Dynasty had strong confidence and pride, such as Gao Xianzhi led the Anxi army to fight against Talas. Although he was defeated by the betrayal of the traitor, thousands of troops still broke out.

The next year, Feng Changqing, who succeeded the governor of Anxi, continued to lead the Anxi army to fight against Dabolu and Boxian, and returned.

Failure is not scary, and if you win it back, this is the pride of the Tang army and the courage that the Northern Song Dynasty never possessed.

The Tang Dynasty, which has hundreds of thousands of troops, is no longer afraid of the Khitan.

"Your Majesty, do you want to contact Goryeo and Bohai Kingdom? Let them cooperate with each other?"

Wu Qing suggested softly that the Shooting Department also wanted to make contributions to this Northern Expedition, and there would be no such good opportunity in the future.

"No need!" Li Jia waved his hand and looked up. He saw that the flowers, plants and trees were filled with white snow, heavy, as if bent the branches and leaves.

"Bohai and Goryeo are just looking powerful, but they are just relying on the geographical advantage. The army is not good enough, and they don't have the courage to act."

"Besides, if you tell them the news, wouldn't it be leaking? Teammates like this are too common, so we have to be more careful."

Wu Qing was silent.

Li Jia ignored him and looked into the distance. He suddenly remembered this Northern Expedition, or rather, this was his last personal expedition.

Although every personal expedition can bring him great prestige, the accompanying risks are unpredictable. After all, not everyone's donkey cart skills can travel 200 miles at night, and the Khitan cavalry cannot catch up with it.

He also does not have the unique skill of crossing the river with beams like Wang Baobao.

There were countless officials persuaded by the court. Everyone thought that the son of a thousand gold medal could not sit in the hall and the war was too dangerous, so the emperor would better not go.

But how did they know that once Youyun is lost, it will take five hundred years. This sense of compulsion that only people in later generations have made Li Jia desperately want to solve it with his own hands.

This kind of pleasure is difficult for ordinary people to understand.

The cold wind rises and falls, and a large number of willow catkins are blowing, mixed with snowflakes and ginseng, making it look particularly beautiful.

Li Jia tightly wrapped in fur and fur, sat in a carriage and came to the imperial camp outside the city.

The imperial camp absorbed the elite imperial guards of Zhou and Song dynasties, and the imperial camp made up for nearly 50,000 elite infantry cavalry, with a scale of 150,000. It was divided into dozens of camps, evenly distributed around Luoyang, protecting the capital of the Tang Dynasty.

Among them, not everyone is in the capital, such as 5,000 people stationed in Tongguan, 5,000 people stationed in Mengjindu, etc. In a dangerous place, there must be an imperial camp.

Therefore, outside Luoyang City, there were only 130,000 imperial camps, and there were only 13 large camps.

With wine and meat, the emperor asked the group of loyal soldiers of the Imperial Camp in the first month of the year. After a while of concern for his well-being, boxes of yellow, green, and slightly red copper coins were placed in front of everyone.
