Chapter 850 The invincible Lin Yiyong can't be allowed to play, it's not time to completely defeat the Liao people...

"The construction of the Great Wall is a long and big project!"

Li Yan rode on the back of a lion and led a team of people to inspect the construction.

The township army was conquering the most elite Central Plains, but he didn't go south at all.

Because it is not needed.

If the commander-in-chief of the Western Army is still able to adapt to the way of teaching, and the extra achievements are actually very brilliant, but there is no support from the family of generals behind him, and the support of Liu Fa, Liu Zhongwu and others with a slightly inferior military status, if the Song Dynasty Central Committee does not drag this army The back legs of the army, on the contrary, gave them full support. Even if the Western Army is a long-fighting division, it is a veteran and strong army after all, and there is still a battle with the rising rural army.

Of course, it is basically a fantasy if all these "ifs" are to be achieved, and now let alone all of them are achieved, it is just that none of them will be achieved.

Zhe Keshi and Zhong Shidao were escorted to Beijing. Song Ting crazily dragged the Western Army back, refused to give any support, and improvised to practice the navy. Such enemies were handed over to Lu Junyi, Zhu Wu and Wu Yong. Kill the chicken with a sledgehammer.

Naturally, Li Yan would not go together. He chose to go north from Yanyun, and came to the border between Yanyun and Liao Kingdom's Zhongjing Road, inspecting the reconstruction of the Great Wall, and confronting the Liao army who might take advantage of the opportunity to go south.

After the recovery of Yanyun, the Central Plains took back the barrier against the grassland nomads, but this barrier was not created out of thin air. In fact, it still depends on the mountains and rivers and the construction of the Great Wall. Therefore, before Lu Junyi attacked the Zhongjing Road and continued to expand the border. In fact, it is Close to the "400 mm iso-precipitation line" studied by later generations.

This line sounds strange, but it is actually the dividing line between semi-humid and semi-arid areas, the dividing line between forest vegetation and grassland vegetation, and it is also the line where the Great Wall was built.

Just like during the Tang Dynasty, the boundary between the Tang Dynasty and Tubo was about 400 meters above sea level, and the line where altitude sickness would appear if the altitude was higher. isoprecipitation line".

Because further north, the precipitation and temperature cannot meet the requirements of crop production, and the way of survival of farming civilization will not work.

This is an inevitable watershed, which is not changed by human will. The ancestors of the Chinese nation built the Great Wall on this line. It is not a coincidence, but a natural law adapted from continuous exploration.

However, the Khitan people occupied Yanyun for [-] years. Of course, it was impossible to build a Great Wall to block themselves in their own territory, but to destroy it if they could. Therefore, after Li Yan took over, he chose to rebuild the Great Wall.

He has considered the Great Wall of the Ming Dynasty in later generations, but according to the current financial situation, he first chooses rammed earth walls at key positions, and then builds walls with blue bricks.

Some people may think that without the tall and towering green brick Great Wall, how can it resist foreign invasion?Didn't it come in right away?

There is no need to worry about this. The stability and civilization of the farming people are completely inferior to the nomads. On the contrary, the sharp weapons of the nomads are horses and cavalry, and the main protection of the Great Wall is not the people of the foreign race, but the horses under the crotch of the foreign race.

The rammed earth wall is indeed hard to stop people from climbing, but a large number of horses can't get through it. The kind of fast galloping and leaping over obstacles can only be done by a thousand-mile horse or even a lion.

From this function, the Great Wall can be regarded as a permanent horse-rejection pile, or a reverse ditch. In terms of solidity, because the rammed earth is used, the soil is compressed greatly, and it is often harder than stones. , is really not randomly broken.

Of course, if you really want to break through from a certain point, you can definitely do it, but in this way, the Great Wall can play a second role, which is to delay the enemy's invasion, give your own warning, and block the retreat.

Nomads broke through a point of the Great Wall and came in. After they burned, killed and looted, the route to bring back the spoils was also fixed, and they had to return from the original gap. Dumplings, the greatest advantage of the nomads, the mobility of the army is gone.

On the other hand, the Great Wall allows the Central Plains regime to move troops quickly, which is equivalent to building a highway between the mountains, and then passing the warning of the beacon tower, so that limited troops can support various places. There is no need for a million soldiers like the Song Dynasty. Defending the border puts heavy pressure on the country, and at the same time, the quality of the army continues to deteriorate.

For nomads, the most deadly is the economic blockade.

Today, there are still a large number of merchants from the Liao Kingdom sneaking southward, bypassing the mutual market and trading with merchants inside Yanyun. Then you can only go the official route.

The black market and smuggling are unavoidable after all, so in history, the border guards of the Great Wall, in addition to guarding against foreign invasions, also arrested inland businessmen for smuggling to foreigners, selling salt and iron to them, and earning huge profits.

"Two thousand years up and down, one hundred thousand miles in length and width", why the Great Wall is the treasure of Chinese civilization, there is really too much wisdom and symbol of farming civilization in it.

So Li Yan definitely wants to build the Great Wall. This is a matter related to future generations, and has nothing to do with whether the current generation is strong or not.

However, in terms of engineering quantity, we must also consider the capacity of the current regime. We cannot follow the example of Yang Guang, regardless of the life and death of migrant workers, and overdraw the country's strength.

"These Khitan descendants and captured Xi people must be supervised carefully, and no deliberate abuse is allowed."

Before defeating the Liao army in Hebei and Shandong, the soldiers who surrendered cut off their hands and put them back. However, since the end of the Battle of Yanjing, the soldiers who surrendered did not cut off their hands. Such orders, after the inspection at the moment, were emphasized again.

Chen Da, who was in charge of the fortification of the Great Wall of the capital and prevented the surrender of soldiers, took the order: "Yes!"

At this moment, a horse was approaching from a distance, and Yang Xiong came up to him, and said with a solemn expression: "Chief Instructor, the scouts have heard about the military situation, and the Liao army is under pressure!"

"This group of bullying people are finally here..."

Li Yan turned the horse's head calmly: "Go, go to the front line!"

When a large banner appeared in front of the formation, cheers erupted in the formation of the township army, and the Liao army, which was slowly advancing from afar, stopped immediately.

The invincible Lin Yiyong is on the front line again!

Yelu Yanxi, who was in the middle of the Liao army, said coldly: "The Taifu expected it again. It is really Lin Chong who came to guard the defense line of Yanyun's northern border!"

Xiao Wuna coughed lightly, and sighed: "This just shows the strength of the township army, they have been able to divide the troops into two groups, and Lin Chong is not immersed in the current achievements, he is still invincible in the charge General!"

Yelu Yanxi rolled her eyes, full of displeasure.

But in just one year, the Lanling King aged so fast that it was unbelievable that people in their fifties were as old as they were seventy. This is why Yelu Yanxi has endured so far. He can die of old age by himself, but he doesn't have to bear the infamy of killing the Grand Tutor.

So at this moment, the Emperor Tianzuo looked to the other side: "What do you think, Brother Yu?"

Yelude took a deep breath, he knew very well that his "brother king" had become a thorn in the Liao Emperor's side since he took possession of the Zhongjing Road, but the Jurchen tribe continued to grow in the Tokyo Road, and he still didn't want to be killed by a group of people after all. The domestic slave turned over, and at this opportune time, he chose to ease the relationship with Yelu Yanxi.

Leading the army to the south at this moment, it is precisely because the township army is going to conquer the Central Plains and take the opportunity to recapture Yanyun. Unexpectedly, it encounters the enemy he is least willing to face, but it gives him hope: "Lin Chong came to the front line personally, This is our great opportunity, this person has no successor yet, as long as he is killed, the forces under his command will immediately fall apart, Yan Yun will return, and the vast land of the Southern Dynasty will also let our Daliao cavalry gallop!"

Yelu Yanxi smiled and said: "That's very good, there are many soldiers under Yudi's command, and there are a lot of talents. I'll wait and see how you accept Lin Chong's head, and you will be ashamed!"

This is almost undisguised, just to use the enemy's hand to weaken the domestic enemy, but added a sentence of shame, Yelu Dezhong had to be framed.

He was already mentally prepared, and began to order: "Qion Yao Nayan, you are the vanguard general, Aric, you... Huh!"

However, before he could finish his arrangements, the opponent's township army rushed out, causing the Liao army to blow up:
"How could it be him?"

……

"Brother, you don't have to do it yourself, just watch how we defeat this group of Liao dogs who are at odds with each other!"

Just as the senior officials of the Liao army looked at this side with fear, Hua Rong came to Li Yan's side in the township army formation, and said nervously.

There is no doubt that although he is convinced of his brother's martial arts, a leader who has no heir to the front line in person puts too much pressure on everyone.

If there is a good or bad thing to do, who has the ability and prestige to lead the next township army?Neither Hua Rong nor Lu Junyi can do it, let alone the rule of Yanyun, Hebei and Shandong. The current good situation will really disappear.

Li Yan understands this concern, and he will not say that he is sure nothing will happen. He nodded and said: "Don't worry, in the current Liao Kingdom, if I don't play, I won't play, otherwise I will defeat the opponent, and it will be beneficial." We are the ever-growing Jurchen."

"What I'm thinking about right now is to make the defeat of the Liao Kingdom less ugly, continue to suppress the Jurchens in the northeast, and temporarily prevent them from going west..."

While the generals seemed to be pardoned, they looked at each other in blank dismay, feeling a little weird.

But all the commanders and generals think about how to make the enemy lose and lose. The more casualties, the more brilliant the victory.

Their chief coach is worried about how to make the enemy lose without losing so badly...

This may sound absurd, but considering the overall strategic situation, this must be done, so after weighing the three options, Li Yan chose the safest one: "Bring Wu Yanguang up."

The order was conveyed, and soon a fast horse came forward, sitting on it was Wu Yanguang, who was once known as the number one warrior in the Liao army and was captured alive by Li Yan in the Battle of Yanyun.

Li Yan looked at the research product of Qi Shu: "Do you still remember our agreement?"

Wu Yanguang's figure is still burly and majestic, and he also held his neck high for the other generals of the township army, but facing this terrifying head coach, there was an unconcealable fear in his eyes: "Remember!"

Li Yan ordered: "Then go, I will keep my promise!"

Wu Yanguang was silent for a moment, clenched Fang Tian's painted halberd in his hand, slapped his horse out, and came to the front of the two armies and shouted: "Wu Yanguang is here, Liaogou will die!!"
