Chapter Forty-Seven: Construction Is More Meaningful Than Destruction (I)

The bitter cold winds howling from the Arctic Ice Sheet have slowed down over time.

And the sun, after a winter of napping, seems to be stretching its waist.

Gradually, Mother Earth awoke from her deep slumber, opened her eyes, and began to take care of her abandoned back garden. The blades of grass everywhere are no longer the withered yellow of autumn, and the wind and frost of a winter have faded all its color and returned to the earth. When spring comes, new blades of grass sprout their shy greenery.

In the warm spring breeze, birds with loud voices are singing happily and flying between the blue sky and white clouds, thousands of little lives are stretching their waists triumphantly, stretching their bodies that have rested for a winter. Animals awakened from hibernation endure the burning hunger in their stomachs, and eagerly rush from their hiding places to the vast natural world, greedily preying on a single piece of food that can fill their shriveled bellies.

The north winds and blizzards that had dominated the prairie began to retreat, and the rivers and lakes slowly unsealed in turn, and the accumulated frost and snow slowly melted, and below the snow-melted slopes, the clear snow water converged into a trickle, like a rushing waterfall, flowing and falling to the depression of the foothills.

Many of the jagged thatched roofs in the city of Kedun still have a little unmelted spring snow. The Tula River, which has thawed and flowed again, is already green with willow buds, and the grass and trees are turning green. A few swallows flew in and out under the eaves, mending their homes destroyed by the wind and snow with spring mud.

A group of knights drove their horses with whips, carefully avoiding puddles on the road, and slowly walked out of the south gate of the city of Kedun.

-- The roads were muddy and damp after the snow melted, and the melted snow soaked the rammed earth so soft that it was easy to sink into it. The puddles accumulated on the road are like traps, some are deep and some are shallow, the shallow ones are not above the instep, and the deep ones can even bury people in them!

However, once you leave the city gate, the surrounding scenery suddenly opens up. As far as the eye can see, the spring sun gently soothes the cold winter tormented earth, everything gradually recovers from the cold and lonely slumber, and on the deep black earth after the ice and snow melt, the tender green sprouts stand tenaciously in the cold morning breeze, so that the earth is covered with a thick green carpet...... But this is not the pasture or weed that nomads are accustomed to, but the high-tech crops of the 22nd century that Doraemon sowed shortly before: "Seven Days of Wheat" and "Edelweiss Alfalfa".

“…… This wheat...... Is it true that you can reap the harvest in just seven days after planting? And it grows in the early spring when the snow has not melted? ”

Looking at the strings of heavy ears of grain, as well as the farmers who were toiling in the wheat fields, Yelu Dashi felt that his worldview was about to be subverted, "...... Even if the yield per mu is only a few buckets, it can be sown dozens of times a year - this yield is far more than the fertile soil in the south of the Yangtze River! ”

――In fact, before the Yuan Dynasty, under the influence of the civilization of the Central Plains, a small amount of agricultural production was distributed on the grasslands of Mobei. However, due to the cold climate, scarce precipitation, and poor cold and drought tolerance of early crops in the Mobei grassland, it is always intermittent. After the rise of Mongolia and the conquest of the Quartet, the steppe nomads gained an absolute psychological advantage over the farming people, and began to despise agriculture and advocate nomadism, so that the nomadic economy was unified in the north, and the agricultural foundation left over in the early days was finally abandoned by the Mongols, and it was not until the Qing Dynasty that it was slightly restored.

To get back to the point, on both sides of the river near the city of Kedun, the Khitans originally reclaimed a small amount of farmland, driving the Han people in the city to grow some barley, rye and other cold-tolerant grains, but the management was extensive and the yield was pitifully low, and the average harvest per hectare of cultivated land could only be 25 kilograms per year, which was better than nothing. Most of the grains they usually eat can only be obtained from the southern Han land through trade, and they are not known how many layers of skin have been stripped by those black-hearted profiteers.

But after changing to this [Seven Days of Raw Wheat]...... Kedun City has been able to get rich by exporting grain, okay?!!

Moreover, if this kind of [seven-day wheat] can be promoted in the entire Mobei grassland, so that the entire grassland will become plugged into the south of the Yangtze River...... Then the person who can take out this kind of divine object will definitely become the food and clothing parents of millions of nomads in the entire grassland in one fell swoop, and the Buddha of ten thousand families, and be worshiped by every nomad with extreme piety, and the words he says are more effective than any hero and khan in the grassland!

Because, the hero's sword only levies on them cattle and sheep, but this miraculous crop can keep them from starvation forever!

Thinking of this, he couldn't help but become more and more jealous of Guo Jing, the "immortal" of the Song Kingdom, but some kind of terrible thought came out of his heart......

※※※※※※※※※※※※※※※※※※※

Compared with the horror, shock, and fear of Yelu Dashi, the traversers are very calm about this: in Doraemon's pocket, there are all kinds of incredible things that are too many to count. What is the wheat that can be harvested in seven days, and there is also an indoor rice that can be planted directly on tatami mats, and can be harvested in only half a day after sowing, and thousands of rice cakes can be made from a single room of paddy fields!

Therefore, Wang Qiu watched the horses munch on the tender, juicy and nutritious [Edelweiss Alfalfa], while leisurely humming an old song that is very suitable for the environment: "...... The vast end of the world is my love, and the flowers are blooming at the foot of the green mountains......"

At the same time, Doraemon is proudly showing off the achievements of biotechnology in the 22nd century to the 21st century buns.

“…… This kind of [seven-day wheat] is a cold-tolerant, drought-tolerant and barren-grade crop jointly researched by scientists from all over the world through guò genetic engineering in the early days of the future Antarctica 6, which can adapt to a variety of harsh climates, especially cold and drought, and is known to grow on icebergs! ”

Doraemon held up a bunch of ears of wheat and introduced to Guo Jing and Nobi Nobita, "...... In addition to this, it has the advantage that it is easy to cultivate and does not require intensive cultivation. As for the disadvantages, the yield of each round is relatively low, and it is not resistant to heat and waterlogging, and the harvest will be lost after being flooded. Moreover, the resistance to pests and diseases is poor, so it can only be planted in cold and dry places, which is just suitable for the Mongolian steppe......"

However, no matter how powerful this [seven-day wheat] is, if it is planted on a large area on the Mongolian plateau, it will still be problematic.

Truth be told, the Mongolian steppe is not very suitable for crops. From ancient times to the present, why has the economy of the northern nomads not been as good as that of the Central Plains? Why did these nomads keep moving south to invade the Central Plains? Because their natural environment is too barren and fragile, it is only suitable for extensive nomadic herding - there are too few rivers on the grassland, the average annual precipitation is only 200 mm (about 1,500 mm in the Jiangnan region), the water resources are not very sufficient, and they are close to the desert, which is easily attacked by the desert, and the phenomenon of sandstorms is even more prominent. In these relatively harsh natural conditions, the vast pastures are a natural bulwark against the desert, preventing soil erosion and the movement of sandy soil, which is not possible for most crops that need to be harvested regularly. If the grasslands are forcibly reclaimed on a large scale and crops are planted without sufficient technical conditions, the Mongolian grasslands will become desertified in a very short period of time, causing unprecedented damage to the ecological environment of the entire northern China.

At the end of the Qing Dynasty and the Republic of China, China once reclaimed the Mongolian grassland, which was still in the relatively humid Monan grassland, but the result was still more and less - after the grassland was reclaimed and destroyed, soil erosion was very strict, and the nutrients of the soil would soon be lost, and the cultivated land obtained could only be abandoned in a few years.

Therefore, after the establishment of New China, Beijing's desert has invaded less than 2o kilometers away from the first square, and the state has to spend huge sums of money every year to build shelterbelts, prevent and control desertification, and pay for the indiscriminate reclamation of the year...... It's really a sad story......

In view of the above tragic lesson, as a very high-caliber cat-type machine, Doraemon has already thought of this trouble for the Khitan people, and has prepared a countermeasure to solve it - that is, another pioneer in the polar development of the future world: [Edelweiss Alfalfa]!

Alfalfa, native to West Asia and Europe, is known to be the king of forages, and it is this barren-tolerant and excellent forage that allowed medieval Europeans to maintain a large cavalry force, rather than suffering from a lack of horses, as was the case with the Chinese of the Song Dynasty...... The [Edelweiss Alfalfa] that Doraemon took out can grow even in barren places like Antarctica 6 for livestock consumption.

With the assistance of this thing, as long as the nomadic herders in the Mobei area around Keduncheng do not abuse the soil power, after planting several rounds of [Seven Days of Raw Wheat] in early spring every year, and then replanting the cold-tolerant [Edelweiss Alfalfa], they can rely on this excellent forage grass with nitrogen fixation ability, provide a large amount of organic matter for the soil, and make the land fertile. At the same time, the land can be covered with vegetation at all times, avoiding soil erosion and desertification.

At this moment, under the deliberate adjustment of the Doraemontong guò [weather control device], the newly cultivated wheat fields around the city of Kedun are in a good weather, and the growth of both wheat and alfalfa is in the best condition. Simple metal farm tools such as hoes and sickles are also available in the open supply of Doraemon - just find a few samples and put them in front of the [replica mirror] to take a picture - the only trouble is that any crop requires hard work, and there is a lack of agricultural tradition in this part of the desert north, and there are many good sheep herders and milking herders, but it is difficult to find experts in growing crops.

Fortunately, there were many Han Chinese, Xi and Bohai people living in the city of Kedun, and the rye and barley outside the city were also cultivated by them, and they had some farming skills - although they did not dare to compliment the land they planted, and like the wild fields, they almost never fertilized, watered, and did not bother to remove insects or anything. But at best, the level of the agricultural people is much stronger than the traditional nomadic peoples such as the Mongols, Turks and Khitans.

In short, the "large-scale production movement" in the spring of 1127 A.D. in the city of Kedun was basically smooth, and the harvest was also considerable.

What's more, the traversers have unwittingly changed the economic and social form of this grassland......
