The Zhengdong Army, which had been repaired for three days in the Yanshan camp, finally started, this was a bloated army of up to 130,000 people, and the Tianshen was driven back to Chang'an by Ji Xuan to repair and replenish, and Yanglin and all the personnel of the Zhengdong Army began a long-distance march on the grassland.

The cool autumn wind blows the flags whistling, in another month or two, there will be another scene, the grassland people will hoard a large amount of hay before this Mid-Autumn Festival, the head of the king of Goryeo Yanglin has secretly sent people to Gai Suwen's camp, I believe that the Goryeo army will withdraw from the grassland in the near future, Yanglin's strategic task is to take the Murowei and the Yan Ya mainland, as for the recovery of the northern grassland occupied by Xue Yantuo, it is the task of the Zhenbei Army, anyway, the number of troops there is not much, as long as the news of the main force of the Eastern Army attacking their nest is received, They will take the initiative to retreat, and the one who really wants to engage the enemy is still the Eastern Army. In fact, the Zhenbei Army has other secret missions.

In the big tent of the Goryeo coalition army, the miserable face of Gai Suwen announced the news that the Tang army attacked the capital of Goryeo, and the king of Goryeo died tragically at the hands of the Tang army, and the big tent was anxious, compared to this news, what made several other countries more unacceptable was that Gai Suwen wanted to lead the army back to Goryeo, appease the people, and inherit the news of the throne, in the entire north, the Goryeo army was the absolute main force, as soon as they withdrew, the armies of the remaining four countries combined were less than 50,000, and they were not at all the opponents of the main force of the hundreds of thousands of Zhengdong Army, you must know that the Zhengdong Army was not the Zhenbei Army, They are so well equipped that they are already the best in the world.

If Gai Suwen withdrew, the five tanks and chariots would also be taken away by him, although Gai Suwen generously gave all the northern 3,000 li grassland to Shikoku, but the lord of Shikoku knew that he could not hold this place at all, and the two countries of Silla Baekje announced their withdrawal from the battlefield after Goryeo, and returned home, and finally the lord of Murowei and the head of the Jin Ya tribe, who had obtained the 3,000 li grassland for nothing, did not know whether they should be happy or cry.

When he inherited the throne of Goryeo, it was the day when the envoys of Chang'an rushed to Goryeo to sign the letter of state and bring back the five kings, and in the secret agreement between Yanglin and Gai Suwen, Gai Suwen was not allowed to use the armies of Silla and Baekje to let them return to their country, although Yanglin said to Gai Suwen that the Zhenbei army would intercept their return route and relieve the pressure on Gai Suwen to unify the peninsula, but his real purpose was to change the armies of these two countries to change hands, Invite the lords of two small countries to Chang'an for tea.

Li Ke leisurely with the shaking of the tank and shaking his fat, in the autumn, the cool breeze, doing on the shell of the tank tank is far more comfortable than riding on the back of the horse to grind the thighs, Yanglin is not used to long-distance horseback people, so he and Li Zhi are also squatting on the tank shell with the army marching, three thousand miles of grassland, this walk is afraid of more than a month.

"Brother-in-law, this vast prairie has a vast area, lush vegetation but no one else, if it can be turned into a field, I don't know how much grain I can harvest in the Tang Dynasty!" Li Zhi looked at the grass waves drifting in the wind with some emotion, he knew that Yanglin had implemented a huge environmental transformation plan in the Western Regions, and hundreds of thousands of Tibetan prisoners were placed on the edge of the desert, concentrating on opening the river and planting trees, and in less than a year, it had achieved a small effect, at least the water volume of the Yellow River was much clearer and smoother after the turnover of several small tributaries excavated.

And the imperial court has long forbidden the cutting down of trees in the land of Guanzhong many years ago, over-exploitation, and now the ecological environment of the land of Guanzhong is much better than in history, but the entire Central Plains has already gone through thousands of years of farming, and the output is very limited when chemical fertilizers have not yet come out.

"You are right, the Great Northern Wilderness can become the northern grain production center of my Datang, but at present, the development is still early, with the high-yield grain in southern Xinjiang, Datang has no worries about food, now my Datang population is only 50 million, the output of the existing fields, has greatly exceeded our consumption, grain is cheap and hurts farmers, as a manager, we must pay attention to macroeconomic regulation and control, so that domestic prices are balanced, so this land, we can only use it as a reserve land now, after two or three generations, Datang has a population of more than 100 million, this place may be slowly developed. ”

Yang Lin had nothing to do anyway, so he explained to him, but Li Zhi and Li Ke, who listened to it, nodded again and again, the idea of this exposition is high, but the centennial development of the Tang Dynasty.

"Yes! Since my father ascended the throne for 16 years, my Datang has rarely had heavy casualties in major wars, but has subdued such as the southern Xinjiang, the Western Regions, Tubo, Hui and other northern grassland ethnic groups, the population has increased more than twice, and it is still growing at a number of more than 10% every year, in the long run, within ten years, the population of Datang can exceed 100 million, and then go down, I really don't know how many people in Datang will be a hundred years later, we will lay this big territory in advance, and let future generations have a place to live, brother-in-law, this is the reason why we continue to expand abroad! Li Zhi sighed with understanding.

In fact, Li Zhi's views on this area are far less profound than Li Ke, Li Ke, who single-handedly drove the development of the land of southern Xinjiang, has the most intuitive understanding, he has done ten years of infrastructure construction in southern Xinjiang, and has also done ten years of ideological work for ethnic minorities, just ten years, the productivity of the people in southern Xinjiang has increased several times under the guidance of him and a large number of Han officials, not only got rid of the original barren life, but also transformed their original habitat into more suitable for human habitation, the population increased dramatically, and the Tang Dynasty occupied these lands, It's just that some short-sighted people can't understand the concept of Datang at all, and they are fighting fearlessly, but they don't know that if they take a step closer to Datang, their good days will come soon.

"Not only that, great unification, reducing fearless war deaths, is a matter of great significance to the development of the entire human race, you may not know much about this world, in fact, it also has a vein, after our natural science and technology level reaches a certain level, we will know, how to make this world exist for a longer time, my tree planting and sand control plan in the Western Regions, opening rivers and retaining water, are all in the regulation of the ecological environment of this world as much as possible, can you imagine the consequences of sand and dust spreading throughout the world? Can you imagine the consequences of severe soil erosion, which led to thousands of miles of red land in Guanzhong, while the people downstream were threatened by floods?

To grasp these natural contexts, we can compete to transform it, so that our ecological environment is better, and to do this, first of all, we must occupy all the land, unified planning, maybe a hundred years later, we can make the raging yellow sand desert disappear, let it become a thousand miles of jungle, maybe a hundred years later, we can make the turbid Yellow River as clear as mountain spring water, become the source of drinking water for all the people of the Tang Dynasty, and to achieve these, we must first improve our education level, Let everyone understand these truths and take action for them, which is why I have spared no effort to build Chang'an Academy and spread this new knowledge. ”

Yang Lin spoke, Li Zhi and Li Ke's eyes became more and more intense, Yang Lin's starting point has already risen to the entire human race, the whole world, because he knows that in the future generations, environmental problems are big problems that threaten the survival of all human beings, and if he puts environmental problems in this world in advance of thousands of years in advance, then a small policy made now may affect the environment of the whole world for tens of millions of years, at least the entire Asian environment now, It is entirely possible that this will be changed after the implementation of his series of regulatory measures.

"Brother-in-law, I will definitely learn your skills with my heart and spread it out." Li Zhi said firmly, and Li Ke also swore in his heart, during this time, he has begun to contact some of the textbook knowledge of Chang'an Academy, as smart as him, even if there is no teacher to explain, he has learned the primary school curriculum thoroughly within half a year, and now he is not as eager to return to southern Xinjiang as he was at the beginning, and now that southern Xinjiang has embarked on an orderly development track, he wants to stay in the north, or go to the Western Regions, and really do something for the Tang Dynasty, or for mankind.

"Hehe, it's good to have a heart, don't put too much pressure on yourself, these things can't be rushed, it takes many generations of continuous efforts, and right now, what we want is to quickly solve the battle here, the winter of Changbai Mountain, even if it is not as good as the plateau, it can freeze many people to death, once it snows, our tanks may not be able to drive." Yang Lin said a little worriedly.

Although the baggage team carried winter clothes, with the winter clothes equipped by the Tang army at present, it can resist the cold of Guanzhong at most, but the winter in the northeast is much colder than Guanzhong, once it falls into the snow, it does not need the enemy to fight, and its own army will also suffer heavy losses.

"The Murowei and the Murves may know this, too!"

The silent Li Ke only said one sentence, but said the main point like the finishing touch, the reason why these two ethnic groups chose this area as their habitat is not because of how good this area is, but because other people are not rare here, because the weather environment is indeed too bad, they only need to use this harsh environment to repel the enemy army again and again, and Goryeo, which is close at hand, is not without ideas about them, but has never succeeded, this is the reason.

Hearing this, Li Zhi's face darkened, and he began to fantasize about what the army surrounded by the vast snow was like. Yang Lin glanced at Li Ke with appreciation, this guy is really a smart person, and during this time, he has to consider some tactics for fighting in the snow. (To be continued.) )
