Great Warriors of Sui and Tang Dynasties

Chapter 877 The Son of Heaven Guards the Gate of the Country

"After this battle is over, will the Great Wall be rebuilt?"

Xiao Yu asked the emperor.

The Great Wall, since the Warring States Period, countries have begun to build the Great Wall to defend against foreign enemies. The Great Wall built by various countries and dynasties added up, and the east and west are already more than ten thousand miles long.

There are even two sections of the Great Wall in the land where the river replaces the north, the outer Great Wall in the north of Mayi, and the inner Great Wall in the south of Mayi. It can be said that the land that replaces the north is the most important thing to defend against the northern nomads.

After the founding of the Sui Dynasty, the Great Wall was built many times. When Yang Guang succeeded to the throne, he built the western section of the Great Wall outside Mayi, from the bank of the Yellow River in Yulin County to the vicinity of Shahukou.

The role of the Great Wall is still very obvious, so it has been built in all dynasties.

But the emperor shook his head.

"I deliberately pushed the border to the southern edge of the desert and to the north of Yinshan Mountain, so there is no need to build the Great Wall."

The locations of the Great Walls of the past dynasties are actually roughly the same. This line of the Great Wall is actually the [-]mm equal rainfall line discovered by later generations. This is also the borderline between farming civilization and nomadic civilization.

This line is also the dividing line between semi-humid and semi-arid regions.

To the north, there is drought and little rain, and it is difficult to grow agricultural crops.

Therefore, for thousands of years, the Great Wall has always been on this line.

As far as Luo Cheng is concerned, if he guards this line, it means that many strategic highlands will actually be surrendered, and he will be in a very passive defensive position.

He even hoped to push the border to the north, to the Yin Mountains, to the southern edge of the desert.

"The six towns of the Northern Wei Dynasty, Guanfang?"

Zhang Xutuo thought of the six defense lines of the Northern Wei Dynasty. The Northern Wei Dynasty was originally the Tuoba tribe of Xianbei, and finally defeated the northern Hus since the Western Jin Dynasty subjugated the country, and unified the north.After he founded the country, he set up his capital in Pingcheng, which is also known as Datong in later generations, in Yunzhong at this time.

Because the capital was close to Yinshan Mountain, Rouran, the nomadic grassland overlord in the north, often threatened Pingcheng. Therefore, the Northern Wei Dynasty built a [-]-mile Great Wall along Yinshan Mountain, and established six military towns.

The Northern Great Wall of the Northern Wei Dynasty was built in the north of Yinshan Mountain.

However, this Great Wall lacks terrain support in the north of the Yin Mountains, and the role of the border wall is more prominent. It is not as dangerous as the Great Wall on the southern line.

"The best defense is offense. I thought that to deal with the nomads in the north, it is not enough to blindly build the Great Wall for defense. We must be able to fight out. Fighting and pulling, both kindness and strength, so that we can stand firm place of defeat."

Although Xieli has not yet been defeated, and the Daibei and Hetao areas have not yet been regained, Luo Cheng has already started planning for the future defense of northern Xinjiang.

He no longer tried to repair the Great Wall, nor did he want to strengthen the pass.

It's just that a thousand days to be a thief is not like a thousand days to guard against a thief.

The northern border is so long, and if you want to defend it across the board, the defense line is too long and there are too many loopholes.

It's better to advance to the north, build cities and forts there, set up military towns, and garrison soldiers and horses.Replace the Great Wall defense line with fortress chains.

Although the fortress chain is not a wall without gaps, the fortress chain is strong in active attack, replacing passive defense with active attack, and pushing the border to the outside of Yinshan Mountain can greatly increase the buffer area.

The arable area in Daibei does not need to be a buffer zone for frontier wars, it can be a farming area.And if Monan Daibei and other places are all placed behind the border towns, the nomadic tribes in the north will have no stronghold to attack the Central Plains.

When they crossed the desert and headed south, they had to face the northern frontier town of the Central Plains Dynasty. Unlike in the past, the north and south of the Yinshan Mountains, the Hetao area, and even the Daibei area became places where they grazed and raised sheep. Attack directly from Monan.

"Do not repair the Great Wall!"

This is the first time Luo Cheng has spoken to the military officials of the imperial court.

"Don't build the Great Wall." After Zhang Xutuo heard the emperor's words, he also felt that his blood was boiling. Even if the Sui Dynasty was so powerful, he dared not say that he would not build the Great Wall.

Luo Cheng's plan was to set up military towns in the north of Yinshan Mountain after recovering the northern border. The initial plan was to set up six towns in imitation of the Northern Wei Dynasty, guarding several important mountain passes in the north of Yinshan Mountain.

In this way, places such as Monan and Saibei were placed behind the defense line of the military town, and then the people were relocated to farm and reclaim wasteland, just like Liaodong outside the Guan, making it a frontier full of living borders, rather than the desolate buffer zone of the past .

The climate at this time is far warmer than that of later generations.

Therefore, the rainfall line such as [-] mm is actually further north.

There is plenty of rain, and there are many rivers. Hetao and Daibei are all rice grain rivers. Similarly, in the eyes of grassland tribes, these places are also the most fertile pastures.

The [-] army divided into four groups to capture the rest of Yanmen, and the emperor's [-] army surrounded Yanmen, and they were not idle.

A branch of Qingqi was scattered outside Yanmen City.

And a branch of auxiliary troops is doing civil engineering work under the city.

Dig trenches and build earth walls outside the city, encircling Yanmen County City. On the other hand, red cannons and small and medium-sized catapults are also being transported from the rear.

Under the city, there are many artisans and civilians recruited, who are doing their best to build all kinds of siege equipment, such as ladders, trench bridges, rush cars and so on.

The emperor was not in a hurry to attack the city. Facing a big city like Yanmen, it took 20 people to attack it for more than a month. He didn't want to attack by force, and he was not in a hurry. The city, too, must fall.

Officials stationed in Loufan Second County, Yanmen, also began to lead the soldiers of the Qin Army to organize the re-registration of the household registration population and the clearing of the fields and gardens.

A new military mansion was established, a village was established, and the land was allocated and granted. There was a busy scene in the rear.

Many old wealthy families were relocated by the emperor this time. Even if they were not implicated in the rebellion, they were ordered by the emperor to buy back the land and replace it with others.

The prefects, magistrates, magistrates, magistrates and other officials of the two counties have all been replaced, and even the local subordinates have undergone a major reshuffle this time.

As for those bandits and horse bandits before, it is even more inevitable this time.

Regardless of whether you are a Turkic herdsman, half herder, and half robber, or a servant of a powerful landlord's family, half civilian, half bandit, you will all be wiped out.

With the backing of 20 troops, the suppression of bandits went smoothly. The land was cleared, the registration of household registration was also smooth, the distribution of land, the granting of land, and the immigration and farming were all proceeding in an orderly manner.

Although such a large army gathered in Daibei and consumed a lot of food and grass, this time the emperor still took out good things such as salt, tea, and wine to attract business and transport grain, which greatly reduced the burden on the government.

And the family property, money and food of those collaborators and defectors confiscated in the two counties also raised a lot of food and grass.

In Yanmen City.

Although Liu Wuzhou had [-] soldiers in the city at this time, he became more and more panicked as each day passed.

"Awarding the army, why hasn't Jieli Khan's Turkic reinforcements come yet?"

If this continues, it won't be long before Luo Chengcheng is fully prepared, and when the time comes to attack, it will definitely be a thunderbolt!
