The system takes me to travel

What a great phrase, I am naked, I am cool, an old antique who doesn't know the value of things.

I looked at the old emperor and said, tell me, what's the matter?

Prophet, yes, the emperor called me a prophet, do you have a way to solve this natural disaster?

This is easy! What you can't solve, I can solve easily.

You are such an arrogant boy! Unless you are a god, it is impossible for you to do this.

How do you know I am not one? All of you follow me, go out to the meeting room door, and when everyone is present, I will suddenly release the things I brought.

The thing that appeared in mid-air stunned everyone present.

The only exception was Ye Yifan, which shocked everyone.

I took those things that could create rain, used my spiritual power, sent them up to the sky, and scattered them everywhere.

Then I asked them to go back and wait for half an hour.

At this time, a minister questioned, "Are you fooling us like this?"

What is that thing? It can fly into the sky and make it rain.

You think we are easy to fool, but your subjects are not that good, old man.

I have no patience. You are not worth my fooling. You said you gave me money, but you invited me here.

The person who invited me here didn't say anything. Don't you even believe him?

That's right, you are used to being superior, so who would you take seriously?

Little girl, you are talking nonsense. I am not young. I am fifteen years old.

Just as they were arguing, the sky became covered with dark clouds, and it looked like it was going to rain.

Not long after, it really started raining.

Dark clouds gathered and soon it began to rain.

It’s really raining, it’s really raining. I didn’t expect that this girl is so capable.

The emperor was very pleased and asked me what reward I needed.

I asked him, you know, I am a person from the future, and there will be no emperor in the future.

You have also seen our future world. Everyone is equal, right?

You asked me what I want. Do you have any dragon robes that you no longer wear? Could you give me a few?

I will take it back and give it to my brother in the future. After all, dragon robes will have become extinct in the future.

The dragon robe you are wearing can appear in the future. Don’t you feel honored?

It is such a glorious thing that your dragon robe can be preserved after thousands of years.

The emperor was about to get angry, but when he heard what I said.

He was somewhat tempted, but at this moment, a minister spoke up.

No, that’s not allowed. Only the emperor can own the dragon robe, no one else can own it.

I ignored those ministers and asked him if he would give it to me in exchange for the technology of making rain.

Deal. Seeing that I wanted it, Ye Yifan agreed on behalf of his father.

The old emperor didn't say no, so I wrote down all the things that can make rain.

The raw materials commonly used for artificial rainfall are dry ice and silver iodide.

Dry ice is solid carbon dioxide. When it is scattered into the air, it will vaporize immediately, absorbing a large amount of heat, causing the temperature of the clouds to drop below zero, causing water droplets to condense into ice crystals and form rainfall.

As a chemical substance, silver iodide has extremely low toxicity and is very efficient in producing ice crystals. Usually, only a small amount of silver iodide needs to be spread to induce precipitation through clouds.

And here’s the easiest way to make your own dry ice.

Pour a little baking soda into a bottle, then pour in the same amount of vinegar (white vinegar is better). After pouring, immediately insert the bottle stopper (with a tube), and then put the other end of the tube into the second bottle, and what goes in is carbon dioxide.

Step 1: The simple method is to prepare a carbon dioxide fire extinguisher first, and then put a canvas bag on the mouth of the liquid carbon dioxide container.

Step 2: Open the fire extinguisher safety, turn on the switch, and quickly release the gas in the cylinder. You can see white "snowflakes" falling near the nozzle, which is dry ice.

Baking soda, also known as sodium bicarbonate, can be made in a variety of ways:

Synthesis method: also known as the soda ash method or soda ash carbonization method, is to use the high-temperature soda ash produced by the soda ash equipment calcination system to accelerate the mother vaporization process and provide qualified caustic soda solution for subsequent operations.

There is also the double decomposition method: baking soda is produced by the double decomposition method of raw salt and ammonium bicarbonate, and the optimal process conditions are determined through orthogonal experiments.

Natural alkali method: also known as natural alkali carbonization method, it utilizes abundant natural alkali resources to generate sodium bicarbonate crystals through carbonation reaction.

I have told them how to make it, and I received several sets of dragon robes.

My brother likes antiques, so I'll give him a few dragon robes.

The drought here has been basically solved. After hard work, these ancient people finally succeeded in making a simple device for modern rain bombs.

The emperor personally led the soldiers to transport the devices to the worst-hit areas and ordered them to be launched.

Following loud noises, dark clouds appeared in the sky, followed by heavy rain.

The people cheered and knelt on the ground to thank the emperor for saving their lives.

The emperor looked at the people in the rain and his heart was filled with relief.

He knew that his efforts were not in vain. He successfully solved the problem of drought and saved countless lives.

From then on, the emperor paid more attention to the development of science and technology. He encouraged Lu Ban's family to continue to explore and innovate, and make greater contributions to the prosperity of the country.

At the beginning, only a few princes and princesses came to my mansion.

Later, a minister got to know about my place, and soon young ladies and young men from various families came to book a place for the whole year.
