Doomsday Super Farm

Wang Bing roared angrily, swung his ax and struck Zhang Jun's wife.

But his actions frightened his wife.

She wanted to stop Wang Bing and pushed Wang Bing's arm with her hand.

As expected, Wang Bing's ax was a little deflected and slipped past Zhang Jun's wife. However, it managed to survive and fell straight on Zhang Jun's neck next to him!

puff!

There was an extremely dull sound of the blade entering flesh.

Zhang Jun's footsteps stopped.

Wang Bing was stunned for a moment.

Zhang Jun's wife turned her head and looked at Zhang Jun blankly.

Everyone was dumbfounded.

A stream of blood spurted out from Zhang Jun's neck and flew for two to three meters before falling to the ground.

"Ah!" A sharp, almost broken scream sounded in the courtyard of Wang Bing's house...

…

While Li Tianran was eating yogurt and strawberry salad, he watched like a supervisor as those agricultural intelligent robots skillfully harvested wheat and corn and packed them into piles.

"Ding! You have recycled radiation-proof wheat..."

The melodious beeps kept ringing in my ears.

He looked at his mall points at this time.

Exactly one million!

"There are still 16 days, 17 hours and 54 minutes until the second era of destruction comes!"

Li Tianran looked at the scarlet prompt and touched his chin. If the second Destruction Note took away water, then he would have to make preparations from now on.

If you just solve the problem of drinking water, then there is no need to worry at all.

All it takes is a giant water cellar, which is enough to sustain it for a long time.

But what Li Tianran faces now is not just the issue of drinking water.

Irrigation of farmland and water exchange in fish ponds require large amounts of water.

Perhaps the water consumed by changing the water in the fish pond or irrigating all the farmland once is enough for Li Tianran and his sister to drink for more than ten years...

"The artificial lake... no, this is just a huge water cellar at most. Sitting on nothing will not solve the long-term problem." Li Tianran murmured to himself: "As for water wells, I'm afraid they will also dry up after the second era of destruction.

"

"..."

Li Tianran racked his brains and couldn't figure out how to solve the water source problem.

Suddenly, he slapped his head and said excitedly: "That's it! I've thought of a way!"

"Artificial rainfall!"

right!

It’s artificial rainfall!

Li Tianran had been thinking about how to get water from the ground, but he never thought that there could be water in the sky!

In fact, rainfall and snowfall are a very important source of water in the world!

Thinking of this, Li Tianran just did what he said.

At this time, the fish pond has been excavated, and all that remains is to wait until the heating pipe is installed before the fry can be released.

Now Li Tianran can think about other things.

"Artificial precipitation, also known as artificial rainfall, refers to the process of artificially supplementing certain necessary conditions for the formation of precipitation based on the principles of natural precipitation formation, promoting the rapid condensation or collision of cloud droplets and enlarging them into raindrops, and then falling to the ground..." Li

Tianran murmured to himself, he remembered the principles of artificial rainfall very clearly.

Rainfall is mainly related to cloud cover.

Rain clouds are divided into warm clouds and cold clouds. If these two different types of rain clouds are to be artificially enhanced, the materials used are also different.

To make warm clouds (clouds with a temperature higher than 0°C) precipitate or increase rainfall, hygroscopic particles such as salt powder and urea should be sown in the clouds to promote the formation of large cloud droplets, resulting in the formation or increase of precipitation.

If you want cold clouds (clouds with a temperature below 0°C) to precipitate, you need to use airplanes to spread dry ice, silver iodide and other catalysts to produce a large amount of ice crystals, which increases the density of ice crystals in the upper part of the cold clouds and promotes or increases precipitation.

Li Tianran raised his head and glanced at the sky.

Since the sun was destroyed, the sky has been covered by a thick layer of clouds and fog, and although the temperature at this time is very low, it has always been very humid.

This shows that there are many water molecules in the air.
