Black Dragon Kingdom

Then Ace held the other two cups and a tissue with an area of ​​one square meter in his hands.

Suddenly, countless dark clouds appeared out of nowhere in the sky, quickly blocking the sun's rays.

The world darkened.

The wind blows from east to west on the faces of countless members of the Dragon Alliance.

He filled two equal cups with water again.

Then, as in the previous experiment, pour all the water in the No. 1 cup into the paper towel.

under a dark sky.

Gale gusts.

Countless scholars, great scholars, and legendary saints all looked at everything in front of them with the face of seeing the truth.

The mental power moved slightly, and the tissue was fully opened under the control of the mental power, completely exposed to the wind.

Afterwards, Ace also sent the cup filled with water into the wind.

The wind blew against his ears, making a humming sound.

And in his heart, he is like an adult looking at the child he was born, looking at the experiment he is doing now.

Truth exists in nature, but except for a very few truths in nature, most of the other truths are hidden in the deeper world.

It needs someone to discover and use it with talent, so that the other party can show his style.

And on this basis, the rules can be combined with each other to create more powerful rules.

The wind gradually died down.

In the amazed eyes of countless scholars, legendary saints, the paper towel dried up again, while the water in the cup only dropped by less than one-tenth.

The evaporation rate of water, for sunlight, the smaller the contact area with sunlight, the slower the evaporation rate, and the easier it is to store in nature as a water source for food production bases.

Conversely, the larger the contact area with sunlight, the faster the evaporation rate, and the less likely it is to be stored in nature.

The evaporation rate of water is the same for wind. The smaller the contact area between water and wind, the slower its evaporation rate, and the easier it is to store in nature as a water source for food production bases.

The larger the surface area of ​​water in contact with the wind, the faster it evaporates and the less likely it is to be stored in nature.

Grasslands, deserts, Gobi, these water-scarce areas, more than 90% of the water is evaporated by wind and sunlight.

Knowing this, and knowing that their evaporation rate of water depends on the contact area with water.

It's not very difficult to solve this matter.

Ace said calmly.

In his words, more than 90% of the water in nature is evaporated by wind and sunlight.

Only a few are really absorbed by plants and animals.

As long as it can reduce the contact area of ​​water with sunlight and wind.

The water in nature can completely increase several times or even ten times, dozens of times.

Grasslands, Gobi, deserts, with so many water surges, will there still be water shortages?

Certainly not.

With water, the two words of farming are quite easy to solve.

Not to mention anything else, just planting grass and engaging in aquaculture can produce countless foods.

Not to mention that he is still a black dragon with super high-level farming skills such as grafting and farming.

Just plant countless grain tree species on it, and in less than twenty years, a big granary will become a big granary.

If the huge area of ​​more than 90 million square kilometers in the south is fully developed, it will be a vast plantation of more than 85 billion acres.

Raising a population of 150 billion is not the same as playing.

Of course, the premise of all this is to solve the contact area between water, sunlight and wind, and reduce the evaporation rate of water several times and tens of times.

Otherwise, if there is no water, there is no need to think about the food base, it is completely impossible.
