Black Dragon Kingdom

Turn off the magic screen casually, so that the sound of fighting and screams disappears.

He stood up tall from the throne, a pair of scarlet longan eyes slowly shining in the gorgeous palace.

Like a pair of blood moons filled with endless evil breath.

Countless images flashed through his eyes, mountains and rivers, the earth, plantations, the Great Wall spouting countless streams of water evenly, and humans and all races slaughtered into a mass.

Over a myriad of familiar things.

The vast and boundless prairie, the Gobi, and the desert in the southern border of mankind came into his eyes.

In this war, although the wars in other directions are also steadily approaching victory, what he feels most important is the southern territory dominated by grasslands, Gobi, and desert terrain.

After decades of deep sleep, through countless small stories, he has absorbed countless high-level knowledge inherited and remembered by the giant dragon.

He has already completed it, the last piece of his own farming system.

Mountains, plains, ice fields, basins, plateaus, etc., as long as there is water, under his rules of grafting and farming, they can all be turned into granaries that produce countless grains.

Swamps, rivers, oceans, lakes, and other waters can also be turned into endless granaries based on his swamp farming rules.

And now the only thing that prevents him from turning into a granary at the fastest speed is the desert, Gobi, and grassland.

Topographic factors, weather factors, and water source factors, even if trees can be planted in these three areas, the production effect is actually not very good.

A lack of water can cause food production to plummet countless times.

Although grafting and seeding can also make these three terrains produce food, the efficiency is definitely far inferior to other terrains that do not lack water.

Therefore, in order to improve their own farming system.

Let the desert grassland Gobi can also be turned into a granary that nourishes countless lives.

For decades, he has been racking his brains.

He tried his best to supplement this missing corner of his farming system.

Fortunately, as a saint dragon.

After all, he didn't blind the word Saint Dragon for nothing.

The solution finally made him think of it.

In countless little stories.

He watched the mountains and rivers, entered the rivers, walked in the desert, and was burned to death in the fire.

Experienced the joys, sorrows and joys of countless intelligent beings.

As the protagonist of the story, he held a long sword and carried a gold coin. From an ignorant young knight, he traveled thousands of miles all the way, and built a big empire with faith, loyalty, and glory.

He also turned into a goblin, carried a silver coin, was chased and killed countless times by humans, tried his best just to survive, but finally died by the river.

Pile by piece.

Knowledge, faith, courage, glory, sorrow, unwillingness, everything in the world has been experienced by him.

After going through such difficulties, spanning countless times, and gaining countless knowledge.

In the end, he obtained a high-level rule called "Theory of Mountains and Rivers".

And this principle can turn the water-deficient Gobi, grasslands, and deserts into granaries that can grow countless grains.

It is the last link to complete his farming system.

The moment when "Theory of Mountains and Rivers" was born, plain basins, ice sheets, Gobi, grasslands, mountain tops, lakes, rivers, swamps, oceans.

The terrain where all intelligent life in the world can survive will eventually become his eternal food production base.

"Everything in the world, for this dragon, there is nothing that cannot be farmed."

"If there is something to be said, it can only be that I have not seen him."

He proudly raised his faucet, and his eyes were full of admiration for himself.

Ace climbed down from his throne. With a weight of 10,000 tons, every step he stepped on the floor of the hall would make a roaring sound.

The door of the hall was slowly opened.

The golden sun shines into the palace from it.

The whole world has been reflected into a ball of gold.

Stepping on the golden light, he walked out of his palace.

The throne was behind him, slowly shining against the sun.

Ten minutes later.

He came to his little experimental site.

The things inside the experimental field are very simple, just a piece of land, a sheep, four small cups, and two paper towels.

He landed slowly on the ground, with a pair of dragon wings in the air, setting off an endless gust of wind.

But the gust of wind was under his control, but it didn't damage the experiment point below in the slightest.

The two little dragons crawled here early, and the two pairs of big dragon eyes are full of anticipation.

The four legendary saints stood in the distance as bystanders, waiting for another high-level rule to be born.

However, more than a thousand university scholars and hundreds of thousands of scholars crowded together around the experimental field long ago, eagerly waiting for their Majesty.

Looking at the lively scene below, he swooped down and landed on the ground smoothly.

Accompanied by a light roar, he who was extremely irritable and terrifying, suddenly turned into a learned dragon sage.

Peaceful, wise, and blood-colored eyes are extremely gentle, making the two little dragons and other scholars, legends and saints feel sincerely at ease.

"Ace, you are really a miracle in this world, you actually created another high-level rule that has never been born."

"Are you trying to envy me to death?"

Eliza's eyes are full of stars. As a magic dragon, she respects those who can create high-level knowledge.

Especially when this existence was still his own dragon.

"Knowledge comes from nature, from life, and from creation."

"It's there by itself, but I have a pair of eyes that know how to discover, and a soul that can combine."

"This is what makes it appear in the world."

Ace said to Eliza gently.

His younger sister is very smart, so he has always answered Eliza's questions.

Let her grow up quickly.

And what he just said is one of the truths in the world.

Knowledge already exists in the natural world, as long as you have a pair of eyes that can discover knowledge, whatever knowledge you want, in fact, any knowledge will come to you.

Just like the saint who once created civilization and immortality.

He was born in a world without supernatural beings, when ordinary people lived no more than a hundred years.

How short life is.

The development of a civilization can take thousands of years, tens of thousands of years, or even hundreds of thousands of years or millions of years.

With a lifespan of a hundred years, he is just a small bubble in history.

It will be destroyed at any time, and it is simply insignificant.

However, because he was afraid of death, he created the rules of immortality for civilization, and obtained eternal life against the sky.

And lead all the existences in his clan that have contributed to civilization to obtain eternal life together.

From a bubble that will be destroyed at any time, it has turned into a stubborn rock that hangs in the long river of time.

Immortality, immortality.

Looking at the bustling void today, 90% of the credit is on him, so you know how terrifying the other party is.

Really I am standing at this end of history, looking from my footsteps to the endless end, all the later existences are in my thoughts, and the former ones will also exist in my thoughts.

"Knowledge exists in nature. As long as you have a pair of eyes that can discover knowledge, you can have whatever knowledge you want."

Eliza was deep in thought, and a hint of inspiration was about to burst out of her mind in a trance and be understood by her.

Looking at Eliza thoughtfully.

Ace became more gentle.

As for the countless thoughtful scholars and scholars, as well as the four legendary saints.

Selectively ignored by him.

Today's knowledge teaching is mainly for his two younger sisters, Eliza and Elena.

As for them, that is a group of extra heads.

If it weren't for the dragon alliance that he now rules, the ratio gap between fighters and scholars would be too great.

At this moment, they are not qualified to stand here at all.

After all, his subordinates now have more than three million powerhouses above Tier 3.

However, there are only a thousand scholars corresponding to the third level.

And there are only a few hundred thousand second-tier scholars below university scholars.

There are not as many Tier 2 ones as there are Tier 3 ones, and the difference in numbers between the two sides is truly sky-high.

This situation is certainly not normal.

So he allowed them to listen here.

Elena squatted silently on the grass, her big eyes staring straight at Ace.

As an excellent war dragon that focuses all its skill points on combat.

Of course she understands that war does not just exist on the battlefield, but war exists in a country and every part of a nation's daily life.

More food means more population!

The larger the population, the more fighters!

With more fighters, there is a greater chance of victory on the battlefield.

The development of the rear is sometimes more important than the war at the front.

Therefore, she is also quite eager for high-level knowledge.

Glancing at the well-behaved Elena, Ace turned his head.

He strode to the front of the experimental apparatus.

Looking at the four cups and two tissues in front of him, his eyes narrowed.

With a thought.

The invisible force of thought made the four cups and two paper towels suspend in the air.

Let two cups and a paper towel come to yourself.

Experiments are slowly underway.

Elena and Elisa, plus four scholars and countless scholars and scholars, stared wide-eyed and observed.

I saw that Ace poured the same amount of water into two equal-sized cups (the contact area between the surface of the water and the air after being filled with water is one hundredth of a square meter).

Then pour the water in one of the cups on the paper towel, so that all the water in the cup enters the paper towel, and no drop falls outside.

Then he opened the paper towel completely, and its area was as high as one square meter.

Then Ace put another cup containing water and the paper towels that had turned into wet paper towels under the sun at the same time.

Ten minutes later.

under sunlight.

The water level in the cup filled with water has dropped by less than one-tenth.

The wet paper towels turned into dry paper towels again.

Ace placed the dry paper towel and the cup whose water level had dropped by less than a tenth in front of Eliza and Elena.

Loudly said:

"Under the same amount of water, the larger the contact area between water and sunlight, the faster the evaporation rate."

"Based on this principle."

"We can reduce the volatilization rate of water in grasslands, Gobi, and deserts by several times."

"Let it have more water sources and be able to feed more plants, so that it can gradually become a food production base that can produce food."

"As for how to use this knowledge!"

"It's easy!"

Or casually waved in the land in front of him.

Dense small pyramids made of mud instantly filled the ground under their feet, and they were connected to each other to form one after another cone-shaped waterless puddles at their junctions.

The magic moves slightly.

The heavy rain also fell in due course.

In the torrential rain, countless water droplets fell on the land composed of densely packed small pyramids.

According to the characteristics of water to go down.

The water flowed quickly towards the small puddles formed by the interconnection of the pyramids, and slowly formed small puddles with water.

The water was quickly stored.

The rain is gone.

The blazing sun was gathered by Ace on this land.

The water in the field began to evaporate rapidly.

After ten minutes, it was completely evaporated.

Ace thought again.

The land densely packed with small pyramids turned into ordinary land in an instant.

The dry land ushered in the same heavy rain as before.

After the same amount of rain fell.

The rain stopped again.

Ace once again gathered the same sunlight that hit the small pyramid land before.

However, this time, because the water flow was not concentrated, the contact surface between the water in the land and the sun increased by ten times, and the speed of evaporation was also ten times faster in an instant.

A minute later, the land became dry again.

Countless scholars and scholars, and even the four legendary saints, all stared wide-eyed.

I was very excited in my heart.

what did they see

The solution to the water shortage problem that plagued countless arid and water-scarce areas was directly placed in front of them, and a small pyramid would do.

No no no, not just little pyramids.

A small soil bag with a strong tower is also fine. You can directly hold the soil into a cone to form a quadrangular pyramid or a pentagonal pyramid.

As long as it can reduce the contact area between water and sunlight after the rain falls, any shape will do, even digging a cone-shaped pit on the grassland is the same.

And his reasoning is actually so simple.

As long as the contact area between water and sunlight is reduced, the evaporation rate of water can be reduced several times, or even ten times.

This method, with a little use, will no longer lack rainwater in arid and water-deficient areas. After all, the evaporation rate of water has been reduced several times or even ten times.

How could there be a large-scale water shortage?

There is no shortage of water anymore, and the production of food is still not on the hook.

And the production of grain is good, and other things are easy to talk about.

Elena and Eliza have opened their mouths.

The two of them were a little dizzy.

I really wish I could give myself a slap.

They have seen the scene of water evaporating under the sun countless times, and they have seen countless times the scene where a small puddle cannot be evaporated by the sun for more than ten days.

As a result, high-level knowledge was placed in front of them, but they missed it time and time again.

How many times have I missed it, the scales on my body are not enough, now it really confirms what Ace said, knowledge is in nature, and you need a pair of wise eyes to discover them.

Looking at a large group of countless dependents and two little dragons who looked at him with adoring eyes.

Ace waved his hand and said, "The rules I'm showing you now are just part of my rules."

"The remaining few rules will definitely not be worse than the one in front of us."

"The combination of them is the complete rule of the law of mountains and rivers."

"Just like the swamp farming rules I created at the beginning, the swamp farming rules include food chain rules, correct destruction rules, and plant living space rules."

"The combination of the three rules is the complete marsh farming rule."
