[Six hundred chapters, although Heng Yi is sick with a cold, but Heng Yi is still working hard]

Visiting shops, watching the bustle, military training, going out hunting, hibernation, these are the main things that can be carried out in the cold winter, which are somewhat boring, and there is no way to change them, unless it is to make the cold winter into a comfortable spring and autumn.

An interesting thing happened in Zhongjing City, a soldier who had made a first-class merit actually used coins to buy several large pieces of glass in the shops of the Ministry of Commerce, and prepared to install them on the doors and windows of his house, so that in winter, the sunlight could shine directly into the house through the glass.

Because the production of large pieces of glass is very low, Xia Guozhong also used glass on a large scale in the palace, even in the mansions of ministers and county magistrates, there was no large-scale use of glass, which made the price of large pieces of glass very high, and the soldiers who had made a first-class contribution could barely afford it.

When the soldier's house was replaced with glass doors and windows, it immediately attracted a large number of onlookers, and the onlookers were envious.

"The windows with glass are so nice, the sunlight shines directly into the room, it's so bright."

"When the room is not dark, there are more things that can be done, you can sit directly on the kang and knit sweaters, without squatting in front of the stove."

The first person bought the door and window glass, and saw the benefits of installing the door and window glass, many people were moved, but there was no second person to take action, most of the people did not have coins in their hands, and a small number of people had coins in their hands but could not buy much glass, so they could only wait for the next year to save money and sell the glass.

Time flies quickly, in a blink of an eye, winter has ended, entering the eighteenth year of the Xia calendar, and it is also the last year of the second five-year plan of the Xia Kingdom, this year Su Yan is fifty-one years old, and Ping He'an's age has also reached twenty-eight years old.

War is the constant theme of the Xia Kingdom, after the end of the regular court meeting in early spring, the cavalry troops stepped into the battlefield of the Western Front, the expeditionary corps stepped into the battlefield of the Eastern Front, and the two fronts fought at the same time, which almost did not affect the development of the Xia Kingdom, but accelerated the development of the Xia Kingdom to a certain extent.

Especially on the Eastern Front, there are currently nine C-type ships in the hands of the Xia State, and the C-type ships are currently the fastest ships in the Xia Kingdom, with a single ship carrying as much as 20 tons.

In order to deliver the spoils of the expeditionary legion faster, the Ministry of Transport formed a fleet of ships of the same type, and the slowest A-type ships formed a fleet, which was specially used to transport the expeditionary legions to the various tribes on the new route.

Anyway, no matter how many ships are mobilized, they can't meet the needs of the expeditionary legion, and it is most suitable to use the slowest A-type ship to transport the expeditionary legion, and the fast ship is used to transport the trophies of the expeditionary legion back to the Xia Kingdom.

This year, the Ministry of War set a goal, to advance the front to the snake tribe, the snake tribe is the biggest target of the Xia country in the new route area, the Xia country wants to take down the snake tribe with a population of more than 20,000 more than five years ago, it is more troublesome to take the Japanese tribe camp and the fishing tribe.

After all, the area where the Sun Tribe camp and the Fishing Tribe are located is relatively close to the Xia country, while the snake tribe is far away from the Xia country, and the snake tribe is more populous and stronger than the Japanese tribe camp and the fishing tribe, so the Xia country must send more warriors.

The snake tribe will be the first goal of the military department in the next year, and it is also the most important goal, as long as the snake tribe is taken, there will be no more war on the eastern front battlefield next year, how to take down the snake tribe, the military department bosses need to discuss carefully.

Several successive spring rains in a month will moisten the dry earth, and spring rains are as expensive as oil, and with the help of spring rains, this year's crops will definitely grow more luxuriantly, but the Ministry of Rites, who is in charge of observing and recording the weather changes, feels that something is wrong.

"Compared to previous years, it seems to have rained a lot more this year."

It's only a month of weather changes, and it can't know more things, so the Ministry of Rites has drawn a circle of this matter, as a key object of observation, climate change has a very big impact on the Xia Kingdom, and the Ministry of Rites has to pay attention to it.

For example, the natural disasters that affected the entire earth ten years ago were truly terrible, with only more than 360 days in a year, and the most serious year of the natural disasters was one hundred and fifty-one days in winter, and the remaining three seasons were only 210 days, and there were only 70 days left in each season, which was only two months and ten days.

You must know that Xia Guo's setting for winter is the time period from water freezing to ice melting, in fact, the winter time should be longer, and the most terrible effect of increasing the winter time and shortening the time in other seasons is the drastic reduction in crop yields.

The Xia Kingdom is better, there are enough food reserves, while the tribes outside the Xia Kingdom do not have enough food reserves, so they can only wage wars to snatch the food of other tribes, and I don't know how many tribes died out in that natural disaster that lasted for many years.

Natural disasters suspected of being in the Xiaoice period are rare after all, while floods and droughts are relatively common, and they often occur in normal years, but the impact is very small, especially for the Xia Kingdom, which has various preparations, basically no impact.

The farmland of the Xia Kingdom is full of ditches, and when a flood occurs, the excess water flows into the river through the ditches, and when a drought occurs, the Xia Kingdom can drain water from the river through a water wheel, or even use an ox cart or horse-drawn cart to carry the water over.

Most of the cities in Xia are adjacent to the Yellow River, the Yellow River is the source of water, and the swimming fish in the Yellow River are also a source of food.

In years when the flood disaster is more serious, the flood water even spreads to the city wall near the river, and no matter how much preparation is made for such a serious flood disaster, the reduction of crop yield has become inevitable.

It doesn't matter if the crop yield is reduced, the food reserves of the Xia country are very large, even if there is no new food source, the grain reserves are enough for all the people to eat for more than two years, and the key is the safety of the lives of the citizens of the Xia country.

When a flood broke out, the walls were washed down, the houses were washed down, and the people were swept away by the flood, and the chances of surviving were very small.

It's terrifying to think about, even the technologically advanced modern age is not immune to floods.

Both the Great Flood and the Xiaoice Period are natural disasters that are difficult for humans to resist, and both will have a huge impact on human civilization, the difference is that the Xiaoice Period lasts longer and relies on a lasting time to cause a huge impact, while the Great Flood lasts for a short period of time, often only a few months, but will have a huge impact during these months.

Xia Guo does not need to be afraid of the Xiaoice River period, but has to be vigilant against floods, people have no long-term worries, Su Yan does not want to wait until the disaster strikes and then think about making amends, then I don't know how many people will die because of the disaster, so Xia Guo has been making various preparations, preparations for the big flood.

The construction of a city far from the Yellow River is the first preparation, because of the population growth rate of the Xia Kingdom, this year the Xia Kingdom will build seven new cities, four of which are built in the south of Zhongjing City, so that the tentacles of the Xia Kingdom will continue to extend to the south.

The second preparation is a bit messy, for example, the one with multiple trees, many high-ranking officials of the Xia Kingdom don't understand why their king did this, the earth is full of trees, why do we still plant trees, or trees that don't bear fruit.

Modern people know the benefits of a variety of trees, but it is difficult to explain them to people in this era, so Su Yan didn't explain too much, just let them do it and finally complete the task.

In the past year, the total population of Xia will exceed 500,000, and there are tens of thousands of slaves, the population will increase relatively fast, barely catching up with the development speed of Xia Kingdom, and even the daily work time of the people will be less than daytime, about three-quarters of the day, mainly because there are relatively few things that can be done.

Su Yan did not let the people be idle, but added various things for the people to do, planting trees, building river embankments, digging ditches, digging wells, among which planting trees can plant fruit trees and other trees.

Over the years, many people have been slacking off, but because of the reward and punishment plan, their energy has returned, and they are working hard.

……

The end of spring planting, the arrival of March, and the rain after rain, led the officials of the Ministry of Rites to determine that this year is another rainy year, and there is a high possibility of flooding.

The Minister of Rites reported the matter to Su Yan, and then the flood warning letter with the king's seal was sent to all cities in the Xia Kingdom, ordering all cities to pay attention to possible flood disasters.

Su Yan has issued many copies of such a warning letter, the main role is to make the cities pay attention to this problem, make more preparations, and nothing else, in fact, the preparations that each city can make have been done, just wait for the disaster to come and then make other countermeasures according to the situation, of course, everyone hopes that the disaster will not appear.

A flood disaster warning book did not affect the development of Xia Kingdom, except for the rainy days, the rest of the time is still normal work, even Su Yan did not pay much attention to this flood disaster warning book, thinking that even if a flood disaster occurs, it is just an ordinary flood disaster, which will not have much impact on Xia Kingdom.

In the summer, the rain became more abundant, heavy rain after another, because of the continuous rain, the cavalry units and expeditionary corps have given up waging new wars, and the cities in the Xia Kingdom are also under the command of the county magistrate or town mayor to carry out farmland drainage work.

Su Yan received a report from the Ministry of Agriculture that with the current situation, the crop output will be reduced by 10% this year, and if this weather continues, the crop yield reduction will become more serious.

Su Yan was speechless, this natural disaster was not something that Xia Guo could compete with, and he could only reduce the losses as much as possible.

It's also that the Xia Kingdom is too weak, if the Xia Kingdom is strong enough, if the Xia Kingdom can occupy the entire planet, even if a disaster occurs in one area of the planet, it is just a trivial matter for the entire Xia Kingdom, and the power of other regions can be used to support the affected area, and one side is in trouble and all sides are supporting.

The current Xia Kingdom, with a population of less than 500,000, and a territory of absolutely no more than 100,000 square kilometers, is almost a city that is raining heavily, and the entire Xia Kingdom is raining heavily, and a city is affected, and the entire Xia Kingdom is suffering.

If Su Yan is given a population of several million now, then Su Yan will directly expand the territory of the Xia Kingdom by ten times, and there will not be a situation where the entire Xia Kingdom is affected, it is the population that limits the territory of the Xia Kingdom, and there is not enough population to continuously expand the territory, then the difficulty of management will increase exponentially.

For the "weak" Xia country, in the face of disasters, can only save themselves, the Xia people work together to defend their homeland, field/war army, city defense army, reserve army, youth army these four armies are the main force, holding shovels, carrying sandbags, or dredging ditches, or blocking rainwater......

Through the efforts of all the people of Xia Country, the rainy weather finally came to an end at the halfway point of summer.

Yes, it was the disaster that ended first, not that Xia Guo defeated the disaster, and if the disaster continued, Xia Guo would still have to bear it.

In half a month, the disaster situation of various cities in Xia Kingdom was summarized in Zhongjing, and the output of a small part of the farmland was reduced by 10%, the output of most farmland was reduced by 20% to 30%, and the output of a small number of serious farmland was reduced by 40% to 50%.

Two other people were missing in the disaster, with a high probability of death, and more than 20 people were injured, none of which were serious.

Looking at the disaster situation, Su Yan thought of the outbreak of the Xiaoice River period, when the Xiaoice River period broke out, the winter was cold and long, the summer was rainy, floods often appeared, the crop yield was seriously reduced, and the flood disaster just passed was about to catch up with the flood disaster that occurred in the Xiaoice River period.

The most fortunate thing is that there was no major flood in this flood disaster, and if a major flood broke out, even if the city of Xia was built on higher ground, there might be a tragic scene of city destruction and death.

The flood disaster that does not have much impact on the Xia country is mild, the flood disaster that causes a certain reduction in crop yield is moderate, the flood disaster that causes a serious reduction in crop yield is severe, and the flood disaster that causes a failure of crop harvest or even a large number of casualties is a natural disaster.

And this year's flood disaster level is between moderate and severe, and it is barely classified as a severe flood disaster, which has a great impact on the Xia country, the reduction of crop production is one aspect, the postponement of various projects and the suspension of the war on the two fronts of the battlefield is another aspect, it can be said that this severe flood disaster has reduced the development speed of the Xia country this year.

In the eyes of the people of Xia Kingdom, this is the realm of God, only God can make disasters occur, only God can make disasters subside, so when disasters occur, the first thing people have to do is to pray to God, hoping that God can make disasters subside.

The flood disaster has subsided, Xia Guo has returned to the normal development path, what has not been completed before the flood disaster, after the flood disaster continues to be completed, the flood disaster just passed is just a tribulation on the road of development for Xia Guo, and there will be more tribulations in the future.

But no one knew that the floods that had just passed were just the beginning, and that an even greater crisis was coming......
