Imperial Master of the Ming Dynasty

The next day.

Prison, new crooked neck tree.

"Planting trees with chemical fertilizers is really yours."

Zhu Gaoxu was burying the fertilizer residue under the tree, as if hoping that the new tree would grow better. Jiang Xinghuo looked at the other man's actions and was unable to complain.

"So what is the effect of chemical fertilizers on soil-cultured sprouts?"

"Very good." Li Jinglong took over, "I have made three groups of sprouts over there. The sprouts are grown in soil without chemical fertilizers, the sprouts in soil are grown with chemical fertilizers, and the sprouts grown in water are grown without chemical fertilizers."

"In the two groups without chemical fertilizers, the sprouts grown in soil and hydroponically grew almost the same, but when compared with the sprouts grown in soil and chemical fertilizers, they are completely incomparable."

Li Jinglong became more and more excited as he talked: "Moreover, not only sprouts, but also other vegetables, such as rapeseed and lettuce, have also seen obvious differences in their growth."

"Is it good to add chemical fertilizers?" Jiang Xinghuo asked.

"Yes, the growth is completely different!"

Zhu Gaoxu interjected and asked: "Mr. Jiang, in the last class, you said that after five days we can see the effect of chemical fertilizers, and then you will tell us how to use it on a large scale. Does this count as the nine classes?"

Tiehanhan actually wants to prostitute himself for nothing?

Jiang Xinghuo nodded decisively and said, "Forget it, and this class is very important."

"ah?"

Zhu Gaoxu was a little reluctant, so to speak, there are only eight classes left after today's lectures, which is a pity.

"It is indeed important to increase the grain yield per mu." Li Jinglong nodded in agreement.

"That's not what we mean when we talk about chemical fertilizers."

Jiang Xinghuo didn't seem to want to follow the routine today.

Zhu Gaoxu and Li Jinglong were both startled after hearing this.

Aren’t chemical fertilizers used to increase grain yield per acre?

That's not what you mean. What do you mean?

Just as the two of them were deep in thought, Jiang Xinghuo's words were astonishing.

"It's because without the things I talked about, Ming Dynasty would not be able to survive the Little Ice Age in the future, and it would be destroyed!"

The secret room next door.

The eldest prince Zhu Gaochi, who had just brought Xia Yuanji, the Minister of Household Affairs, and Zhang Tianshi, the alchemy consultant, to attend the lecture, was instantly dumbfounded.

The three people were talking and laughing, as if their necks were stuck by a big invisible hand, making them speechless and interrupted at the moment.

Zhu Gaochi felt that his heartbeat was particularly clear in the silent and empty secret room.

He looked at Xia Yuanji with wide eyes, and Xia Shangshu was also dumbfounded.

"Xia Shangshu, what is the 'Little Ice Age'?"

"Your Highness." Xia Yuanji finally came to his senses and said with cupped hands, "I really don't know about this matter. I kindly ask Your Highness to write a letter and explain the whole story to Your Majesty after listening to the lecture. In addition, the matter of the Fertilizer Immortal Statue needs to be decided by Your Majesty personally."

Zhu Gaochi took a slow breath and tried to calm himself down.

He looked at Zhang Yuchu next to him: "Zhang Tianshi is well-read, but does he know what the 'Little Ice Age' is? Why did he allow the Ming Dynasty to perish?"

Zhang Yuchu felt that it was a bit ridiculous. Could he be so frightened just because of the words of the prisoner next door?

Even though Yuan Gong told him about Jiang Xinghuo's magical powers yesterday, Zhang Yuchu had never experienced it himself, so he didn't really believe it in his heart.

But in the face of the eldest prince's question, Zhang Yuchu did not dare to fool him, so he had to say: "I really don't know, but other ministers dare not tell me. If the other person tells me something, as long as it is recorded in history books, or even various miscellaneous books and notes I can definitely relate to the content in it."

Zhu Gaochi also believed this.

Zhang Yuchu was not bragging, but because Longhu Mountain started from Zhang Lu, the Five Pecks of Rice Cult of the Three Kingdoms, and has been passed down for thousands of years without interruption. The books and knowledge accumulated by dozens of generations are very impressive.

Zhu Gaochi shook his head and said: "It's not that I don't believe in your knowledge, it's just that this matter does sound a bit surprising. Mr. Jiang never makes mistakes without aim. There must be a reason for saying this."

He paused and continued: "No matter what the reason is, based on Mr. Jiang's previous performance, we must pay attention to it. Otherwise, if the Ming Dynasty is really destroyed because of this 'Little Ice Age', it will not matter. , if you know and don’t act, that’s another thing.”

Xia Yuanji said quickly: "What His Highness said is absolutely true."

Looking at the confident Zhang Tianshi, Zhu Gaochi planned that after today's lecture, once his father decided to reveal Jiang Xinghuo's fertilizer technology to the officials, he would do his best to promote the theory of "immortal descending auspiciousness" mentioned by Zhang Tianshi.

After all, although Tianshi Zhang knows best whether there are immortals in this world, Tianshi Zhang and Zhenren Yuan have talked more than once. It is estimated that Zhenren Yuan has revealed Jiang Xinghuo's suspected banishment to immortality to Tianshi Zhang.

Therefore, the fertilizer elixir invented by Jiang Xinghuo was called auspicious by the immortal by Zhang Tianshi.

Come to think of it, this statement is also the result of Zhang Tianshi's careful consideration.

In other words, even Zhang Tianshi, the Taoist leader who knows best whether there are immortals in the world, directly recognized Jiang Xinghuo's status as an immortal.

Because according to Jiang Xinghuo’s words, fertilizer is actually saving Daming’s life!

After all, Jiang Xinghuo's chemical fertilizers have a huge impact on the yield of food crops. If it can be promoted, the Ming Empire will definitely see a turnaround in the future - although this turnaround is still weak, there is finally hope.

"call"

Zhu Gaochi sat on the chair and breathed a sigh of relief.

He thought secretly in his heart: "It's good to have hope, it's good to have hope."

Zhang Yuchu, however, still looked confident, not knowing at all that his unexpected suggestion had confirmed in Zhu Gaochi's mind that Master Zhang recognized Jiang Xinghuo's status as an immortal.

"Mr. Jiang, what is the Little Ice Age? Why did this thing make the Ming Dynasty fall?"

On the other side, Zhu Gaoxu also asked anxiously.

Jiang Xinghuo did not rush to answer his question, but asked instead: "Can you guess from the name, what does it mean?"

Li Jinglong chanted: "Lying in a lonely village without mourning, I still think about guarding the Luntai for the country. I lie down at night listening to the wind and rain, and the iron horse glacier falls into my dream. I must have thought that the 'glacier' in the Little Ice Age is the same as the one in Lu Fangweng's poem. The meaning is the same."

"good."

Jiang Xinghuo nodded and said: "The Little Ice Age is a climate phenomenon. During the period when it occurs, the temperature will drop significantly and cause various disasters. Of course, it will only drop overall. At certain times, what manifests itself is dramatic fluctuations in temperature."

"Well, the temperature is how hot or cold you feel."

"The most intuitive judgment of the Little Ice Age is that rivers that did not freeze at all for hundreds of years turned into glaciers in winter."

"During the Little Ice Age, there would be blizzards in the south where it never snowed, and the north was frozen for thousands of miles. All rivers, large and small, were frozen, and river transportation was almost abolished. Livestock, crops, and people were frozen to death and countless people were frostbitten. Here Under such low temperatures, even in the Central Plains, boiling water will be instantly frozen into white mist, trees, flowers and grass will be completely sealed by ice, and people will feel bitingly cold even if they travel wearing several layers of clothing."

"This is the Little Ice Age."

Li Jinglong almost instantly thought of the impact this disastrous weather would have on the country.

And Zhu Gaoxu blurted out: "Isn't that equivalent to having a disaster year every year and having a fiscal minus 5 every year?"

Okay, this is the aftermath of the last time I played the game.

"It's not just that." Li Jinglong also thought of the painful experience last time and added, "The reduction in food production caused by the cold will trigger a series of chain reactions, such as the rise and fall of insurgents, and the continued reduction in national finances, which will lead to the maintenance of Various expenditures continued to be reduced, thus entering an endless cycle of national subjugation."

The two of them had obviously experienced the difficulty of running a country after experiencing the last immersive game.

As the saying goes, the best is hard and the worst is easy.

It is quite difficult to make the country prosperous, but as long as something bad happens that can cause a chain reaction, it will fall into an endless cycle.

"There is also a consequence."

Jiang Xinghuo said calmly.

"What are the consequences?" Li Jinglong felt as if he had thought of everything he needed to think about.

"We are cold, and our neighbors to the north are even colder. The cattle and sheep are freezing to death. What do you think they will choose?"

Zhu Gaoxu and Li Jinglong looked at each other and thought of four words at the same time.

——Nomadic travel south.

At the same time, the secret room next door.

"Is this possible?" Zhang Yuchu asked in shock.

"What's impossible?" Xia Yuanji looked at Zhang Tianshi strangely.

"Well."

Zhang Yuchu thought: Could this old guy be brainwashed by Jiang Xinghuo? Why did Jiang Xinghuo think such a baseless thing was possible when he said it?

He was silent for a long time, and then couldn't help but raise his hand to rub his forehead.

"The problem is, what Jiang Xinghuo said has no basis."

What made Zhang Yuchu a little embarrassed was that the eldest prince Zhu Gaochi and the minister of household affairs Xia Yuanji simply ignored his reasonable suspicion.

Instead, countermeasures were discussed directly.

It was as if what Jiang Xinghuo said about the future would definitely become a reality.

"Your Highness, don't worry. Our Ming Dynasty's treasury is still very rich. If it's just a few years of cold weather, we just need to get through it." Xia Yuanji next to him comforted.

"No, it's definitely not enough." Zhu Gaochi suddenly shook his head.

Zhu Gaochi paused for a moment and said: "In a disaster year when severe cold weather leads to reduced food production, food is hard currency. The key is how much money can be exchanged for food? If the severe cold really causes a series of chain reactions, such as floods, If there is a rebellion, the court will definitely allocate money, so the national treasury will probably be insufficient by autumn. Spending more money to buy grain will only accelerate the collapse of the national treasury. And now in the court, do you think Lord Gongun will really fight against the country? Are we working together? Even if all the officials can fulfill their duties, what about the corrupt officials below? Most likely, when the country is in trouble, they will not only not provide disaster relief, but will take the opportunity to cause chaos and seek personal gain. This problem is very serious!"

Xia Yuanji sighed: "It would be great if the Mongols could be wiped out."

"In this way." Xia Yuanji analyzed, "As long as there is no pressure from the Mongols to invade south, even if the Ming Dynasty suffers internal disasters for several years, the treasury will not be unable to support it."

"The Mongols cannot be destroyed." Zhu Gaochi shook his head, "The Mobei grassland is huge. Although their warriors are not as strong as their ancestors now, the grasslands and deserts they occupy cannot be permanently occupied by the Ming Dynasty. More What's more, now that the Jingyan has just ended, most of the elite soldiers and generals accumulated during the Hongwu era have been lost, and they still need time to recuperate. Only when they regain their strength can they conquer Mobei."

Xia Yuanji nodded after hearing this.

In fact, from a certain perspective, although the problem Jiang Xinghuo mentioned is a bit far away, it actually exists.

You must know that the Han people were ruled by the Yuan Dynasty established by the Mongols for hundreds of years, and to this day they have always had lingering fears about the Mongolian cavalry. Moreover, although the Northern Yuan Dynasty is now divided, the various Mongolian tribes still rule the huge grassland. The second generation nobles of the Northern Yuan Dynasty, who have experienced how prosperous the Central Plains are, still covet the rich Central Plains and are satisfied that they can only drink the northwest wind on the grassland. Angry at the situation.

Now, Zhu Gaochi must of course solve the problem raised by Jiang Xinghuo in front of him.

Generally speaking, if a cold wave breaks out in winter, food prices will inevitably skyrocket.

At that time, even if the national treasury is abundant, it will be difficult to ensure that the country will not be affected, right?

Who knows when the little ice age Jiang Xinghuo mentioned will come and how many years it will last? What if it lasts for ten years?

"So, what do you think should be done, Your Highness?" Xia Yuanji asked.

"We can only wait for Mr. Jiang's explanation." Zhu Gaochi said helplessly, "Let's see what caused this little ice age, when will it come in the future, and how many years will it last."

Zhang Yuchu thought to himself: If what Jiang Xinghuo said is true, the only way now is to pray to God to bless the Ming Dynasty.

"So what was the cause of the Little Ice Age?" Zhu Gaoxu scratched his beard and asked doubtfully.

"A more reasonable guess is that it is caused by changes in the world's ocean currents and tides."

Jiang Xinghuo explained: "This involves geographical knowledge. Last time I told you about Japan's so-called divine wind, which is also included in this subject. Similarly, the flow of the ocean will also transfer heat, which will also cause the sky to Temperature changes, temperature disturbances in the sea, land and air are actually all affected."

Jiang Xinghuo paused for a moment, trying his best to explain the flow of heat in words they could understand.

"That is to say, during certain periods of time, due to the relationship between the ocean and the tides, the tides cause the cold water in the ocean to float up, and the sky absorbs the cold air from the ocean water and becomes colder."

Jiang Xinghuo looked at the two of them, ready to explain with examples if they didn't understand.

Unexpectedly, the two students were not that stupid.

"Did you understand?" Li Jinglong asked Zhu Gaoxu.

Zhu Gaoxu nodded and said: "I can roughly understand the meaning. Although I have never been to the sea and don't know how the temperature of the ocean changes, the principles are probably the same."

Zhu Gaoxu gave an example that he encountered most often when marching and fighting: "When camping at the bottom of a valley or at the foot of a mountain, it is very hot during the day and very cold at night; when camping on the ridge or top of a mountain, it is not too hot during the day and not so hot at night. Cold. So, since the wind can take away heat, and the changes in cold and heat are different at different altitudes, it would be the same if we put it in the sea."

Li Jinglong continued to deduce with enlightenment: "Since the wind can, then the water should also be able to take away heat. The seawater at different depths in the ocean must be cold and hot. If the tide causes the ice water under the sea to be If it comes up, it will freeze the sky and bring frost and snow to the land."

"And when I went on a cruise in the West Lake, I could clearly feel that the water on the lake surface was cold, and if you fished up from the bottom of the lake, the water brought out from the bottom of the lake would be even colder. The truth should be correct."

The two of them nodded, and they consciously concluded that there should be no problem.

Zhu Gaoxu said: "In this way, what Mr. Jiang said is very reasonable, but it is not clear why the tide changes."

This is the root of the problem. Why was there nothing before but something went wrong during the Little Ice Age? It was because the tides caused changes in ocean currents, which in turn caused the oceans to absorb heat and release cold air, causing the sky to become colder.

Li Jinglong thought for a while and then added: "The changes in tides are reflected in history books, astrology, and calendars. In the past thousands of years, there have indeed been several major tidal changes."

Jiang Xinghuo was a little relieved.

This kind of relief is like watching your child grow up, become sensible, and think independently at a certain moment.

You are worthy of being a student taught by me!

Needless to say now, I will deduce the principles based on daily life experience, and even draw inferences from one instance to another.

In fact, the cause of the Little Ice Age has been controversial, but before his passage, the most reliable theory was the periodic pulsating changes in atmospheric temperature caused by tides and ocean currents.

As for how the tides change, it is naturally related to the cosmic gravity between the moon and the earth. This cosmic gravity will change due to the continuous changes in the arrangement of the earth, moon and sun, and will also be affected by the external influence of solar rays.

Before Jiang Xinghuo crossed, scientists had calculated the historical tidal intensity through mathematical models, and each peak was consistent with the extreme cold period of the Little Ice Age, which preliminarily showed that there was a very likely inexistence between the two. changes in contact.

Of course, Jiang Xinghuo cannot guarantee 100% that this explanation is correct for such an unsolved mystery.

But in any case, there is absolutely no doubt that the cause of the demise of the Ming Dynasty was the Little Ice Age.

"How many years does this tidal change phase usually last?" Zhu Gaoxu asked curiously.

"Generally, a few hundred years."

Jiang Xinghuo replied casually, this was all basic common sense to him.

etc.

Is there something not quite right?

Li Jinglong suddenly opened his eyes wide and looked at Jiang Xinghuo.

Jiang Xinghuo looked at his eyes and nodded.

"Jiang Jianglang, are you saying that this little, little ice age will last for hundreds of years?"

"Of course."

"Then, when did the Little Ice Age of the Ming Dynasty begin?" Li Jinglong was a bit tongue-tied when he spoke.

"It's already started."

The second chapter is still a little bit away, it will be uploaded in a short while.
