The principle of artificial rainfall, winning longevity is clear and abnormal.

However, it is extremely difficult to succeed and make artificial rainfall a reality!

It couldn't be more difficult!

The reason is simple.

The thing used in artificial rainfall is nothing else, it is an extremely special thing that is difficult to make.

This thing, nothing else, this thing is that clean!

The so-called clean is actually not a special thing, it is actually carbon dioxide in liquid form!

Actually, it's very easy to get it.

Because there is carbon dioxide everywhere in the air.

So much carbon dioxide.

So much carbon dioxide!

However, for Win Changsheng, it is impossible to use it directly!

It can't be used directly, so use it as dry ice!

The production of dry ice is extremely difficult, and with the current technical content of Daqin, it is difficult to make it successfully.

Therefore, after thinking about it for a while, Ying Changsheng made a decision, that is, to change the things used in artificial rainfall instead of dry ice.

Well, the demand for dry ice for industry is too high.

Without a dry ice machine, it is extremely difficult to make it clean for artificial rainfall, or in other words, he can't make it at all.

Under such circumstances, Ying Changsheng had no choice but to settle for the next best thing and focus his attention on something else!

That is, ice!

Well, the theory of artificial rain is very simple, that is, let the water above the sky after condensation.

Succeed, let the sky rain above.

In such a situation, it is not impossible to use ice cubes.

At this moment, after a little hesitation, Brother Win Changsheng opened his mouth and said.

"Father, artificial rainfall, there is no way for the son-in-law, father, you wait, the son-in-law will study it, and strive to give you the results in the evening!"

"Okay, then hurry up!"

Seeing that Ying Changsheng was so determined, Ying Zheng hurriedly bowed his head and said to Ying Changsheng.

And Win Changsheng, after retiring, quickly went to the workshop, and then instructed a few craftsmen.

"A few of you, immediately give it to my son, according to this drawing, make an iron model, the top of the iron model, to make a structure that can be opened and closed!"

As he spoke, Ying Changsheng hastily drew a drawing on the ground.

On this drawing, what is drawn is a rocket!

It is a simple model of a rocket that is gray and normal.

And this is the good thing that Win Changsheng has come up with!

Because, if you want to achieve the purpose of artificial rainfall, the most important thing is to find a way to sprinkle these things on the sky.

And this is an extremely difficult thing!

Well!

Of course it's difficult!

The reason is simple, the current productivity is lagging behind.

How can I sprinkle this thing on the sky?

Later generations used anti-aircraft guns to shoot dry ice into the sky!

Or through an in-flight plane, drifting!

But in the current Daqin.

All this is much more difficult!

Extremely difficult to do!

Fortunately, Win Changsheng has already thought of a suitable solution!

His way, if nothing else, is, through rockets!

The difficulty of making this rocket is still very high!

The technical content has always belonged to the cutting-edge technology!

I want to make a rocket that can carry people and launch satellites like the kind of future generations.

That's a fool's dream!

It's just impossible!

However, to make an improvised rocket.

Making one, the kind made of earth, can fly a thousand meters, two thousand meters high, and bring ice to the sky, it is an easy thing for Win Changsheng!

Because this thing is very low-tech.

At best, it's a large sky-skimming monkey!

How high is the technical content of a large monkey?

Winning Changsheng is naturally able to be easily made.

At this moment, after instructing a few craftsmen to make the shell of this large Sky Monkey, Ying Changsheng was not ambiguous, he immediately gathered a few soldiers again, and then, quickly, let them prepare a large amount of sugar and a large amount of gunpowder!

Sugar plus gunpowder!

These two things, in everyone's opinion, are two things that the donkey's lips are not in the horse's mouth.

For everyone, these two things are probably not involved in anything.

At this moment, seeing that the two things that Ying Changsheng wanted were delivered, the soldiers and craftsmen were all confused.

And at this time, Ying Changsheng's command came out again, and only he was heard.

"Prepare some iron pots for Ben Gongzi again!"

"Then, prepare some larger wooden spoons!"

"In addition, prepare some stoves for Ben Gongzi!"

"Nineteen Princes, what do you want these things for? Get the stove here, so much gunpowder, in case something goes wrong......"

The craftsman on the side couldn't help frowning, and reminded Ying Changsheng.

They were really worried about Win Changsheng's safety, but Win Changsheng smiled and motioned to them.

"Don't worry, my son knows what to do, don't worry, don't worry, I can, put an end to all safety problems!"

Under the repeated insistence of Win Changsheng, the craftsmen on the side had no choice but to follow Win Changsheng's instructions and bring over a honeycomb coal stove with an iron shell.

After the stove was flaid.

I saw that Ying Changsheng commanded the soldiers, and first placed the iron pot on the stove.

Then, he quickly turned the stove to its maximum under the stove, and then commanded.

"Pour brown sugar!"

"No!"

The soldiers on the side did not dare to be the slightest slack, and hurriedly poured the brown sugar into it according to Ying Changsheng's instructions, and then, only saw the brown sugar in the iron pot, and in the blink of an eye, it was melted, and after it was melted, Ying Changsheng hurriedly ordered the soldiers to stir it up.

Then, after removing the iron cauldron, under the command of Ying Changsheng, the soldiers on the side poured black powder into the iron cauldron.

Gunpowder poured into the sugar.

After this scene reached everyone's face, for a while, all the soldiers inevitably let out an exclamation.

I couldn't help but whisper in my heart.

Nineteen sons, this is really a waste of things, such a good, delicious brown sugar, and such a good gunpowder.

That's it, it's wasted in vain!

Just when the big guy can't help but think like this in his heart.

Ying Changsheng had already taken the wooden spoon and stirred it in the iron pot, stirring the syrup and those gunpowder evenly.

This scene can be regarded as confusing everyone, and everyone doesn't understand why Ying Changsheng would operate like this.

What is the use of Ying Changsheng's intention in doing this?

Just when everyone was in doubt, Ying Changsheng had already stopped stirring.
