In the blink of an eye, it's November.

When Liu Che saw the thin layer of hoarfrost on the steps in front of the hall, he came to his senses.

Severe winter is coming.

The winter before the Common Era was colder than in later generations.

Especially in the morning, the temperature is often as low as below freezing.

Liu Che took a deep breath, pinched his hands, and walked towards the attic of Jiaguan.

When he arrived at Jiaguan, Ji Yang was already waiting for him there.

"Home!" Ji Di knelt down and presented a few bamboo slips: "This is what you want since the Han Dynasty, the historian's climate record!" ”

Liu Che nodded, took the bamboo slips, and sat down by himself, it seemed that Wang Dao on the side hurriedly asked the eunuch to burn the charcoal stove, and the temperature in the room slowly rose.

Liu Che took the bamboo slips and looked at them one by one.

The brow is getting more and more furrowed.

The historians of the Han dynasty were very conscientious, and they would record all abnormal or abnormal climate and changes.

Since Liu Bangding was the capital of Chang'an, it has been fifty-four years, and the records on this aspect have not been broken.

Plus, the preserved records of the Qin Dynasty.

A picture of the history of climate change in the last 60 years is displayed in front of Liu Che.

After a brief combing, Liu Che's eyes seemed to see the whole world, and they were gradually getting cold.

"In the ninth year of Qin Shi Huang, in the summer and April, it was cold! There are frozen people on the road! ”

"In the second year of the Lv Dynasty, in the summer and May, it was snowing and hail at Taniguchi!"

"Emperor Taizong Xiaowen five years, summer and June, heavy snow!"

and this year, the catastrophic hailstorm in Hengshan country.

In the past accounts. There has even been an anomalous climate similar to the snowfall in June, and in this day and age, science is not good. People naturally thought it was the wrath of heaven.

But Liu Che knew it.

This is influenced by the Xiaoice cycle.

The world is getting cold!

Now in Guanzhong, you can still see citrus, rolling, bamboo forests everywhere.

However, twenty years later, in the first year of Yuanguang, when Liu Che came to Chang'an for the last time in his previous life, he remembered very well that at that time. The bamboo forest in Guanzhong has seen a large-scale death, and it is still very common to roll, and it is difficult to find a trace. The citrus trees of Shanglin Yuan are no longer flourishing.

As a traverser, Liu Che is well aware that this is the global climate cooling under the influence of the Xiaoice Age.

The signal for the beginning of the Xiaoice period is so strong and obvious.

So much so that Liu Che could even get an omen from another direction.

Recent. Liu Che asked people to compile "New Shennong". A large number of agricultural technology books of the Qin Dynasty have been collected.

Among them is "Lü's Spring and Autumn".

Lü's Spring and Autumn Period records the time when winter wheat was planted in the Qin Dynasty, which was on the tenth day after the frost fell.

And now, the sowing of winter wheat in Guanzhong is on the seventieth day after the summer solstice. (Note 1)

In other words, the sowing time of winter wheat during the Warring States period was about a solar term earlier than now, and the current sowing time of winter wheat is at least ten days earlier than the sowing time of later generations!

This is irrefutable evidence of global cooling. It is also a harbinger that the Xiaoice Age is about to come again and sweep the world.

And this time the Xiaoice. From the beginning to the end, it will last for hundreds of years, destroying the current Han Dynasty, Wang Mang's New Dynasty, Liu Xiu's Eastern Han Dynasty, Daozhì Three Kingdoms Disputes, and Wuhu Chaohua until the Sui Dynasty was unified again.

It has a profound and profound impact on the whole of China.

"Dig deep holes, store up grain, and prepare for famine!" If Liu Che was just an ordinary gentry landlord, he would have chosen this and left this lesson to his descendants.

But he is the future ruler of this country.

So, he had only one choice.

"The royal road, the order, convene the officials of more than 400 stones in the lonely palace to discuss the matter!" The fact that Xiaoice River is coming, like a sword of Damocles hanging over Liu Che's head, reminds him that he must hurry up to advance the plan, seize the power, and plan the measures.

If he wants to defeat the Xiaoice River and protect the Liu family's rivers and mountains before this century, the only thing Liu Che can rely on is technological progress and scientific development.

Liu Che is very sure that he does not have the good life of Manchu Kang Mazi, and can have a sweet potato and corn savior.

But on the other hand, the Xiaoice River is both a danger and an opportunity.

An opportunity for civilization to evolve.

Later, Europa encountered the Xiaoice River and was forced to live, which led to great voyages and geographical discoveries, and since then it has taken a leap to replace the East and become the center of the world.

Otherwise, if you can survive in your hometown, why should you risk your life to cross the ocean and go thousands of miles away?

For the Han family, this is the same truth.

The Xiaoice period will lead some peasants to go bankrupt, how to reasonably find a job for these peasants, so that they can support themselves and their families, instead of being in a difficult place, impoverished, and finally desperate, this is what Liu Che, as a ruler, the future emperor must think about.

Not long after, under the leadership of Ji Di, Zhang Tang, and Yan Yi, the officials of more than 400 stones in the imperial palace all arrived one after another.

Obviously, the entire bureaucratic system in the imperial palace, with the connivance of Liu Che, the crown prince, has been faintly divided into three factions.

The newcomer Yang Yi seemed to still have stage fright, and he didn't join the three factions, standing alone in a corner.

"Wait for the ministers to meet the family!" The ministers knelt down and bowed.

"All the ministers are exempt!" Liu Che waved his hand and commanded Wang Dao: "Give you a seat Aiqing!" ”

After a while, dozens of eunuchs and maids came in and prepared seats for the ministers.

"I don't know what the family has to call the ministers?" As the titular boss of the Imperial Palace, the head of the ministers, the family commander Ji Huang asked in the ranks.

Liu Che handed him back the bamboo slips that Ji Di had taken, and at the same time asked Wang Dao to bring "Lü's Spring and Autumn".

Then he said to the courtiers: "Let's take a look at the words marked by Lone first!" ”

Ji Di took it and looked at it first.

He frowned slightly when he saw the part of the bamboo slips that had been drawn red by the prince with a red pen. I was a little puzzled, I don't know what the connection between these things is, why the prince summoned all the ministers so solemnly.

It's just that other ministers, especially Zhang Tang, Yan Yi and others, haven't seen it.

He asked immediately. Obviously, there will be some offends.

So, he passed these bamboo slips to Zhang Tang.

Zhang Tang took it. looked at it and frowned and pondered as a minister of legalism zhang tang was naturally sensitive to these details but, the same. He also couldn't connect the red-painted records in the Spring and Autumn Period of the Lu family with the disasters since the founding of the Han Dynasty.

He thought about it for a while, and passed it to Yan Yi quietly.

Yan Yi took it, and the second monk couldn't touch his head.

So he passed these bamboo slips to Ning Cheng.

Liu Che watched. There is also a degree in my heart, and it is obvious that although the courtiers are divided into different factions because of their different political opinions and ideas, they are still divided into high and low among each other. The order is out.

Although now the drama Meng is not there.

It's not complete. But what is obvious is that at present, the boss is Ji Di, Zhang Tang is the second brother, Yan Yi is the third brother, and Ning Cheng is the first person under the Big Three.

It took about half an hour for all the courtiers to read it.

Only then did Liu Che stand up and ask, "Zhuqing." Do you know what it means for you to see this? ”

"The minister is stupid. I beg you to explain! He bowed his head.

Zhang Tang, Yan Yi and other courtiers also ordered to kneel down and bowed: "The ministers are stupid, I implore the family to solve the doubts of the ministers!" ”

Liu Che couldn't help but be a little disappointed.

But he also knew that this was very normal, if anyone really saw it, then he had to check the eighteenth generation of this person's ancestors, so as not to mix in a traverser.

"Heaven is constant, not because of Shun exists, not because of death, therefore, Tang has seven years of drought, Yu has three years of water!" Liu Che first said this opening sentence to pave the way for his next words.

He took a step forward, looked at the howling north wind outside the hall, and sighed, "It's getting colder and colder!" In this world, it will be even colder! ”

Xiaoice River has just emerged.

The world is still very warm by and large.

However, Xiaoice's footsteps still sounded in Liu Che's ears.

Looking at the ministers who didn't know why, Liu Che simply said directly: "Zhuqing, please see, in the Spring and Autumn Period of the Lu family, the records of Lone Painted Red: It is the moon, the beginning of planting wheat, there is no time to lose, and there is no doubt about the crime." It's the moon, the sun and the moon, the thunder is the beginning of the silence, the stinging insects are in the house, the murderous energy is soaking, and the yang energy is declining! ”

Liu Che looked at Ji Di and the others and asked, "Who knows, what month is this paragraph?" When? ”

Ji Di replied: "Back to the house, "Yi Zhou Shu." There are clouds in the "Interpretation of the Times": the day of the autumn equinox, the next five days, the stinging insects, another five days, the beginning of the water, after the cold dew, the frost and even, and the ten days, the stinging insects are salty, and the time of the record of the Spring and Autumn of the Lu family referred to by the family is the tenth day after the frost, that is, the twelfth day of September! ”

Liu Che nodded and said with satisfaction: "Aiqing is really knowledgeable!" ”

Then, he asked: "Shang Rong, you often go back and forth to the people, know about agricultural affairs, pro-farming, tell me, now, when will the people plant winter wheat?" ”

When Shang Rong heard this, he came out in the envious eyes of the people next to him, and said: "Back to the family, now the people generally rarely plant winter wheat, if you plant wheat, it is generally between July and August, and not more than late August at the latest, otherwise, the wheat ears are small!" ”

Liu Che nodded, looked at everyone, and asked: "The Spring and Autumn Period of the Lu family, written in the ninth year of Qin Shi Huang, has only been eighty or ninety years, why is it that in such a short time, the winter wheat planting time has been so advanced?" ”

He threw out his own assertions: "The weather is getting colder every year!" ”

"If you have any doubts, please look at the disasters recorded by the historians!"

Liu Che picked up the bamboo slips of the disasters recorded by the historians, and said casually: "Since the second year of Qin II, there have been more than a dozen floods in Guanzhong, including the second year of the II, heavy rain in summer and July, and continuous rain from July to September!" ”

"At the beginning of Emperor Taizong Xiaowen, it was rainy, and the rain ended in a hundred days, and after three years, on the thirty-fifth day of the autumn month, Lantian Mountain came out of the water, flowing for hundreds of miles!"

"Look at the drought again, in the twelfth year of Qin Shi Huang, there was a great drought in the world, June was rain, to the dynasty, the second year of filial piety, the summer drought, five years, the drought again, the rivers and rivers were less, and the valleys were extinct. During the reign of the first emperor, in the first three years, there was a drought in autumn, a spring drought in the ninth year, and in the spring of the sixth year of the Later Yuan Dynasty, there was a great drought in the world, in summer and April, the world was in drought again, and locusts were everywhere. ”

"Lone once heard the elders say in Hedong: Take history as a mirror, you can know the rise and fall, and take people as a mirror, you can know the gains and losses!" Liu Che looked at the ministers with an unknown expression. He said heavily: "Please consult the history books, the last time the disasters were so frequent and the climate was so changeable. When is it? ”

"The seventh year of King Zhou Xiao, heavy rain and hail in winter, Hanjiang ice, cattle and horses frozen to death, the ninth year of King You, autumn, peach and apricot fruit!" Abrupt. A voice sounded, Liu Che looked over, and saw Yang Yi come out of the column and bow down: "Sui Ziyun: The world of Li Xuan." The sky is dry and the land is demolished, and my Momen has inherited the bamboo book of the Zhou Room for generations! ”

When everyone heard this, they were almost shocked.

The last hundred years of history of the Western Zhou Dynasty were almost in the midst of famine and constant natural changes.

The Western Zhou Dynasty perished in the famine and the heavenly changes. Until the Zhou room moved eastward. These calamities have come to an end.

And this is also the first intimate contact with the Xiaoice River recorded in the history of the Ming Dynasty in Chinese history.

As a result, civilization was defeated in the face of natural disasters, and the destruction of the Western Zhou Dynasty was used as a sacrifice to survive the Xiaoice River, but the consequences were extremely strict, and for more than a hundred years, the Central Plains civilization was almost crumbling. Until the princes of Qi Henggong Jiuhe, one Kuang world. Under the banner of respecting the king and expelling Xirong Beidi, the Central Plains civilization was revived.

It was Confucius who said: Microtubule Zhong, I was sent to the left!

It can be seen how bad the situation was at that time.

It can almost be said that it has reached the brink of extinction of the country!

At this time, everyone present just remembered that dark time, and they couldn't help but break out in a cold sweat.

For traditional Chinese intellectuals, especially intellectuals at this time, being left behind is their most fearful nightmare!

This is true regardless of faction or position!

So, under Liu Che's persuasion or intimidation, the ministers finally realized what kind of enemy they were facing now.

Now, this demon has reappeared.

And Liu Che's subordinates, in the face of this fact, reacted differently.

Zhang Tang, Ning Cheng and other ministers of the Legalist family all sat upright with expressions of being ready for battle.

Privately, they also began to think about what measures should be taken to deal with possible future disasters.

The officials of the Huang Lao faction and the pro-Huang Lao ideology led by Ji Di were a little confused, and seemed to be a little at a loss, and Ji Di's mind was even more chaotic, and all kinds of ideas were popping up.

For the Huang Lao faction, who is now in charge of the country's major affairs, the calamity that may arise again is indeed a problem they have never encountered before.

I can't think of an idea of how to deal with it for the time being.

However, Liu Che also saw that some people were gearing up and fighting high.

For example, Yan Yi of Confucianism and Yang Yi of the Mo family.

The Mo family understands very well that this school does not believe in the Mandate of Heaven in the first place.

As for Confucianism, we must admit that, at the very least, the current Confucianism is not a faction that rests on its laurels, on the contrary, the current Confucianism belongs to a faction that is positive and wants to make a difference.

For example, the Ram School openly preaches great revanchism, advocating revenge for revenge and revenge for revenge.

Of course, there are also some guys who are full of compromises and concessions, but these people are not the mainstream of Confucianism, on the contrary, they are still non-mainstream at the moment and are excluded from the mainstream of Confucianism.

Liu Che looked at everyone's reactions, he stretched out his hands, and said: "The ancients are not enough to plan for the world, not enough for the future, for the future generations, I think that from now on, we have to think about how to prepare for the worst!" ”

"Including, but not limited to, months without rain, rivers cut off, grain harvests, locust plagues, and floods are repeated!"

Listening to Liu Che's words, the ministers seemed to see that terrible future.

There are even people who are desperate, can there be salvation in such a future? Can man overcome nature?

Under such thoughts, someone said cowardly: "Children and grandchildren have their own children and grandchildren, why should you think about things for so long, maybe, such a thing will not happen, after all, my Han family is virtuous, Taiyi has a spirit, and it may not be a disaster......"

For Liu Che, the biggest advantage is that at this time, there is no theory of heaven and man induction, so there is no public opinion environment where natural disasters are the fault of the emperor.

Therefore, he can also slowly adjust the strategy and deploy the plan step by step.

Liu Che looked at the ministers and said: "According to Gu's estimate, at most thirty years, thirty years later, this kind of calamity will follow one after another, if Gu and Qing do nothing, thirty years later, when these calamities come one after another, Gu and Qing will have to face the calamity today." The bitter fruit of inaction, who wants their children and grandchildren to live in a world full of natural disasters and displaced people. You can leave now! ”

In fact, it won't take thirty years at all.

This round of the Xiaoice has already begun, just because it has just begun, and the impact on the climate is not great.

In twenty or thirty years, the impact of this Xiaoice on the Earth's climate will reach a phased peak.

According to the history of the Ming Dynasty, the period of the reign of the little pig. The Yellow River burst, which could not be blocked for more than ten years, caused a catastrophe in the eastern part of the country. Millions of displaced people gathered at the foot of the Hangu Pass.

However, this is only the beginning, two or three hundred years from now. The whole world will be affected by this round of Xiaoice.

After Zhao Xuan. The cold climate reached its peak, which eventually led to the demise of the Western Han Dynasty, Wang Mang killed himself, and the Eastern Han Dynasty was tortured by his inhuman form.

It is no exaggeration to say that if we do not grasp the deployment measures and develop technology in the last two or three decades, then this world will be the same as Liu Che's original world. Constantly caught in the repeated battles and civil wars of the dynastic cycle law, what is even more terrifying. There will also be five nonsense.

That kind of world is unacceptable to Liu Che!

Because of this, in his previous life, although he was only a prince king, he was still a prince king who was suspected.

However, he still disregarded taboos, desperately developed and promoted science and technology, accumulated talents and strength, and tried to defy the sky.

In the end, though, he failed.

However, he did not regret it!

As a traverser, if you can't change the tragedy, then you can still cross a hair, find a piece of tofu to crash to death!

In this life, he has sat on the throne of the crown prince and has become the future emperor.

There is a large force under his command, so naturally he must use all means to stop the upcoming tragedy.

Crossing through aggravated rebirth, and this country, this nation, could not be allowed to dominate this planet, then, Liu Che felt that he could go to find a rope to hang.

Of course, the meal has to be eaten one bite at a time, and Yang Guang is too anxious to end up in such a situation.

Liu Che is also unwilling to make wedding dresses for others.

He waved his hand, and Wang Dao commanded the eunuchs, carrying a huge map of the wooden slab in Guanzhong, and walked in.

Liu Che took his courtiers to the map and said, "If you talk about fighting the famine, the best way is to build water conservancy!" ”

"Zhuqing, please see, at present, there is only one Zhengguo Canal in operation in Guanzhong, and another Bao Slope is in the exploration and design, Lone's idea is that in addition to the Praise Slope, other Guanzhong water system and irrigation projects should also be put on the agenda, start exploration, study geography and landforms, and prepare for construction!" Liu Che talked eloquently, with Cheng Zhengying and Zhuo Wangsun, the two big financiers, Liu Che was not afraid, and the big construction will lead to the boiling of public resentment.

In fact, when he made the request for 100,000 yuan, he had already taken into account today.

Obviously, the 100,000 yuan that Cheng Zhengying and Zhuo Wangsun atoned for their sins and just used it to build a praise ramp to buy the emperor's father and the military.

Liu Che's idea was very simple, taking advantage of the fact that the state finances were still very rich, and taking advantage of the more than ten years of peace after the Wu Chu Rebellion, to repair as many water conservancy projects as possible, and to develop more new technologies and new equipment.

It is recorded in the history books that the money is rotten in the warehouse.

As a traverser, Liu Che didn't think that such a situation was good.

Money, if not in circulation, is nothing more than some useless metal.

Liu Che looked at the map and thought about it, he was not an expert in water conservancy, but in his previous life, he still knew about many projects of the Little Pig Government.

At this moment, he did not hesitate to take out several key projects in the little pig period.

He pointed to the map and said, "I think that we can dig a channel from Zhengxian, pass through Shangyan Mountain, reach Linjin, connect Luoshui with Weishui, and irrigate several surrounding counties!" ”

This project is the most famous Longshou Canal project of the Little Pig Dynasty, and it is also a model and classic case of the construction of water conservancy projects in the Han Dynasty in later history, creating the first in the history of many projects.

For example, the Longshou Canal was the first underground water canal in China.

Legend has it that after the opening of the Longshou Canal, the land in the Linjin area even released a satellite with a yield of ten stones per mu......

This is, of course, a yield falsified by some people.

In fact, when the production capacity per mu reaches an average of five stones, Liu Che can be happy for half a day.

"Zhang Tang, you take people to Linjin and Zheng County, survey and research, visit the neighbors, visit the elderly, ask for opinions, and then tell Sù Lonely when you come back!" Liu Che instructed, of course, the Longshou Canal is not repaired immediately, Liu Che is different from most political figures in this matter, he likes to investigate first, make a detailed plan, list the plan, and then do it.

Like the kind of person who is self-righteous and wants to do what he wants when he pats his head, Liu Che has always disdained.

Therefore, for a long time, although many ideas often pop up in his head, but every idea, he wants to test it first, investigate it, investigate it, see the reaction, and then decide the next move.

"And here!" After Liu Che finished speaking, he pointed his finger at the runwater. It is also the place where Zheng Guoqu originated.

"The runoff water is diverted to the east, to Shuoyang, and then into the Wei River, and then this new channel will be opened up with the Zhengguo Canal to connect the entire Jingwei River system!" Liu Che pointed to the map and said: "In this way, you can irrigate most of the land in Guanzhong, Ji Di, you are responsible for investigating this matter, because this matter takes too much time, Yan Yi, you are on the side!" This project is the famous Zhengbai Canal Project, which is very famous in later generations, and is the largest water conservancy project in Guanzhong during the Western Han Dynasty.

"No!" Ji Di and Yan Yi hurriedly came out.

Liu Che waved his hand and said, "That's it for the time being......"

These two projects, together with the Bao Slope Road, can almost connect the entire water system in Guanzhong, and can also connect with Luoshui.

The amount of work is extremely huge, even with the support of the local tyrants, Liu Che does not think that it can be done quickly, at least, these three projects alone, there are no more than five years, and they do not want to be completed.

"Yang Yi, Qing stays, the other Qing families, go and get busy!" Liu Che commanded. (To be continued......)

PS: Note: Well, this is a long time to find out the information.

A tearful face~ Well, fortunately, I read something similar when I read books before, and I have some impressions, and I am grateful to Mr. Zhu Kezhen for writing China's 5,000-year history of climate change, and thanks to Mr. Wen Huanran for writing about the climate change in the middle and lower reaches of the Yellow River during the Qin and Han dynasties, and thanks to Du Niang Library for including these unpopular information, otherwise I would have no place to check if I want to.

In addition, the records of the famine and the number jù cited in the book are all historically traceable and recorded in the Book of Han. The Five Elements Chronicles and the General Guide to Zizhi
