Ace then held the other two cups and a one-square-meter paper towel in his hand.

In a flash, countless dark clouds appeared out of thin air in the sky, quickly blocking the sun's rays.

The world has darkened.

The wind blew from east to west, blowing on the faces of the countless Giant Dragon Alliance's curtains.

Once again, he filled two equal cups with water.

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

Under the dim sky.

Gale gusts.

Countless scholars, scholars, and legendary sages all looked at everything in front of them with the faces of the truth.

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

Ace then sent a cup full of water into the wind.

The wind blew in his ears and whined.

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

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

It takes some people to use their talent to discover and use it, so that the other party can show his own style.

And on top of that, the rules can be combined with each other to create more powerful rules.

The wind gradually stopped.

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

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

"Conversely, the greater the contact area with sunlight, the faster it evaporates, and the less likely it is to store in nature."

"And the evaporation rate of water is the same for the 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 greater the area of contact between water and wind, the faster it evaporates and the less likely it is to store in nature."

"Grasslands, deserts, the Gobi, these water-scarce areas, more than ninety percent of their water is evaporated by wind and sunlight."

"Knowing this, and knowing that the rate at which they evaporate the water is in contact with the water."

"It's not that hard to solve this problem."

Ace said in a surging tone.

In his words, more than ninety percent 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 is possible to reduce the contact area of water with sunlight and wind.

Water in nature can skyrocket several times, even more than ten times, dozens of times.

The grasslands, the Gobi, the deserts, and the water have skyrocketed so much, will there still be a shortage of water?

Definitely not.

And with water, the word farming is quite easy to solve.

If nothing else, just growing grass and engaging in breeding can produce countless foods.

Not to mention that he is still a black dragon with the super high-level farming skill of marrying and inoculating the field.

Simply plant countless grain trees on it, and in less than twenty years, a big granary will be formed.

To the south, a vast area of more than 90 million square kilometers, fully developed, is more than 85 billion acres of vast plantations.

Raising a population of 150 billion is not just like playing.

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

Otherwise, if there is no water, the grain base will not have to be thought about, it will be completely impossible.
