Turn off the magic screen casually, let the sound of fighting, and the screams disappear, and watch the mobile version)

He stood tall from his throne, a pair of scarlet dragon's eyes shining slowly in the gorgeous palace.

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

Countless images flashed through his eyes, mountains, rivers, earth, plantations, the Great Wall spitting out countless streams of water, and the killing of humans and races.

Crossing a myriad of familiar things.

The vast and boundless steppe, the Great Gobi, and the Great Desert in the southern border of mankind came into his eyes.

In this war, although the wars in other directions are also moving towards victory, it is the southern border that he feels most important to the grassland, Gobi, and desert terrain.

Decades of sleep, through countless small stories, absorbing countless advanced knowledge of the dragon's inheritance and memory.

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

Mountains, plains, ice fields, basins, plateaus, etc., as long as there is water, can now be turned into a granary for the production of countless grains under the rules of his marrying fields.

Swamps, rivers, oceans, lakes, and so on, on top of his swamp farming rules, can also be turned into endless granaries.

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

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

A single shortage of water can cause countless drops in grain production.

Although marrying inoculated fields can also produce grain in these three terrains, the efficiency is certainly far inferior to that of other terrains that do not lack water.

Therefore, in order to improve their own farming system.

Let the desert steppe Gobi also be turned into a granary that nurtures countless lives.

He has been racking his brains for decades.

He tried hard to make up for this gap in his farming system.

Fortunately, as a Sage Dragon.

After all, he didn't blind the three words of the Sage Dragon in vain.

The solution finally came to him.

In countless small stories.

He looked at the mountains, entered the rivers, walked in the desert, and was burned up in the fire.

Through the joys, sorrows and sorrows of countless intelligent lives.

As the protagonist of the story, he held a long sword and carried a gold coin, from an ignorant young knight to a thousand miles of war, with faith, loyalty, and glory, he established a great empire.

He was also a goblin, carrying a silver coin, and was hunted down countless times by humans, trying his best to survive, only to die by the river.

One pile at a time.

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

After such difficulties, countless times and countless knowledges have been gained.

Eventually, he was given a high-level rule called "The Principle of Mountains and Rivers".

And this truth can turn the water-scarce Gobi, grassland, and desert into a granary that can grow countless grains.

It is the last link to complete his farming system.

When the "Theory of Mountains and Rivers" was born, plain basins, ice fields, Gobi, grasslands, mountain tops, lakes, rivers, swamps, oceans.

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

"Of all things in the world, there is nothing that cannot be farmed for Ben Long."

"If anything, it's that I haven't seen him."

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

Ace climbed down from his throne, weighing 10,000 tons, and every step he stepped on the floor of the main hall would let out one roar after another.

The door to the hall slowly opened.

The golden sunlight shone into the palace.

The whole world has been illuminated in a cloud of gold.

With golden light, he walked out of his palace.

The throne was behind him, shining in the sun.

Ten minutes later.

He came to his little test site.

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

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

But the wind was under his control, but it didn't damage the test site below.

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

The four Legendary Sages stood in the distance as bystanders, waiting for another higher rule to be born.

However, the densely packed number of more than a thousand scholars and hundreds of thousands of scholars had long been huddled around the experimental field, eager to learn and waiting for their majesty.

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

With a light roar, he, who was originally extremely irritable and looked extremely terrifying, suddenly turned into an erudite dragon sage.

Peaceful, wise, and gentle in blood-colored eyes, the two little dragons and other scholars, scholars, and legendary saints felt sincerely comfortable.

"Ace, you are truly a miracle of this world, and you have created a high-level rule that has never been born."

"Are you trying to envy me?"

Yin Lisha's eyes were full of stars, and as a magical dragon, she had special respect for beings who could create high-level knowledge.

Especially when this existence was still its own dragon.

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

"It's there on its own, but I have eyes that know how to discover, and a soul that can combine."

"That's what makes it appear in the world."

Ace said gently to Yin Lisha.

This sister of hiss is very smart, so in the face of Yin Lisha's questions, he has always answered questions.

So that she can grow quickly.

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

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

Just like the saints who created civilization and eternal life.

He was born in a world where there was no transcendence, and at that time ordinary people did not live more than a hundred.

Life is so short.

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

A hundred years of life, he is just a small bubble of foam in history.

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

However, it was because of his fear of death that he created the rules of civilization and immortality, and obtained eternal life against the sky.

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

From a bubble that will perish at any moment, to a stubborn rock that has fallen through the river of time.

Immortal, eternal and immortal.

Look at the prosperous void now, ninety percent of the credit is on him, and you can know how terrifying the other party is.

It is true that I am standing at this end of history, and from my footsteps to the endless end, all the existence that comes after is in my mind, and the one who came before is about to exist in my mind.

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

Yin Lisha was thoughtful, and a trace of inspiration was about to burst out of her mind and be comprehended by her.

looked at the thoughtful Yin Lisha.

Ace became more and more gentle.

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

Selectively ignored by him.

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

As for them, they're a bunch of heads.

If it weren't for the dragon alliance he ruled over now, the gap between the ratio of warriors and scholars would be too great.

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

After all, now under his command, there are more than three million powerhouses above the third order.

However, the number of scholars corresponding to the third order is only 1,000.

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

There are not as many second-order as third-order, and the difference in numbers between the two sides is really a heaven and a place.

This situation is certainly not normal.

So he allowed them to sit in here.

Elena squatted silently on the grass, staring straight at Ace with a pair of big eyes.

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

She certainly understands that war is not just on the battlefield, but in every part of the daily life of a country and a people.

When there is more food, there can be more people!

The more the population, the more fighters!

The more warriors there are, the better the chance of victory on the battlefield.

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

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

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

Strode over to the lab equipment.

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

The mind moved.

The invisible telekinesis made the four cups and two tissues suspended in the air.

Bring two cups and a tissue to yourself.

Experiments are slowly underway.

Elena and Yin Lisa, as well as the four scholars and countless scholars, widened their eyes and observed.

Ace poured the same amount of water into two equal cups (the surface of the water is one hundredth of a square meter when filled with water).

Then pour the water from one of the cups on the paper towel, so that all the water in the cup goes into the paper towel, and not a drop falls outside.

He then opened the tissue completely and covered an area of one square meter.

Ace then placed another cup of water and a paper towel that had turned into a wet paper towel in the sunlight at the same time.

Ten minutes later.

In the sunlight.

The water level in the cup of water has dropped by less than a tenth.

Wet wipes have become dry wipes again.

Ace placed the dry paper towel and the cup, which had only dropped by less than a tenth of the water level, in front of Yin Lisha and Elena.

Loud Voice:

"The greater the area of contact between water and sunlight at the same amount of water, the faster it evaporates."

"Based on this principle."

"We can reduce the volatilization rate of grassland, Gobi, desert, water by several times."

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

"As for how to use this knowledge!"

"It's easy!"

Or wave your hand in the land in front of you.

Dense small pyramids of earth instantly filled the ground at their feet, and they were connected to form one cone-shaped waterless puddle after another at their junction.

The magic flickered.

Heavy rain also fell in due course.

In the midst of the torrential rain, countless droplets of water fell on the land made up of dense small pyramids.

The characteristic of walking to a lower place according to the water.

The water flows rapidly towards the small puddles formed by the interconnected pyramids, slowly forming small puddles with water.

The water was quickly stored.

The heavy rain disappeared.

The blazing sunlight was gathered by Ace on this land.

The water in the field begins to evaporate rapidly.

After 10 minutes, it completely evaporated.

Ace's mind moved again.

The land densely made up of small pyramids turned into ordinary land in an instant.

The dry land has received the same heavy rain as before.

After the same amount of rainfall.

The rain stopped falling.

Ace once again gathered the same sunlight as he had once again shone on the Land of the Little Pyramid.

This time, however, because the water flow was not concentrated, the contact surface of the water in the land with the sun skyrocketed tenfold, and the rate of evaporation was ten times faster in an instant.

A minute later, the land was dry again.

Countless scholars and scholars, and even the four Legendary Sages, all widened their eyes.

I was very excited.

What do they see?

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

No, no, no, it's not just the little pyramids.

The small soil bag of the tower is also OK, and the soil is directly held into a cone shape to form a quadrangular pyramid or pentagonal pyramid.

As long as you can let the rain fall, reduce the contact area between the water and the sun, you can take any shape, even dig a cone-shaped pit in the grassland.

And his reasoning is so simple.

By reducing the contact area between water and sunlight, the evaporation rate of water can be reduced by several times, or even tenfold.

With a little application, there will be no shortage of rain in arid and water-scarce areas, as the rate of water evaporation is reduced by several times or even tenfold.

How can there be a large-scale water shortage?

There is no shortage of water, and the production of grain is not yet a bargain.

And the production of grain is cheap, and everything else is easy to say.

Elena and Yin Lisha have opened their dragon mouths.

The two of them were a little dizzy.

I really want to slap myself.

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

As a result, high-level knowledge is placed in front of them, but they miss it again and again.

How many times have I missed it, and the scales on my body are not enough, but 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 scrolls and two small dragons looking at them with adoring eyes.

Ace waved his hand and said, "The rules I show you now are only part of my rules."

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

"When they are combined, they are the complete rules of the rules of the mountains and rivers."

"Just like the rules of swamp farming that I created in the first place, the rules of swamp farming include the rules of the food chain, the rules of correct destruction, and the rules of the living space of plants."

"The three rules together are the complete rules of swamp farming."
