I was watching short videos and was seen by ancient people

Chapter 253 Necessary for Time Travel—Sulfuric Acid ()

[If I could travel back to ancient times, in order to make great progress in industry, I must master how to obtain sulfuric acid, which is a magical substance known as the "Mother of Industry".

With sulfuric acid, fertilizers, medicines, pigments, detergents, etc. can be produced. Not only that, it also helps oil purification, metal smelting, and the development of the dye industry.

Moreover, the production of sulfuric acid has a long history in our country. In the distant period of Emperor Gaozong of the Tang Dynasty, there was an alchemist named Hu Gangzi. He recorded in detail a method called "Stone Refining and Gallbladder Refining" in Volume 9 of "Yellow Emperor Jiuding Shendan Sutra". This is the ancient method of making sulfuric acid.

It uses iron-containing sulfide minerals, which are distributed in many parts of our country.

And its refining method is also very simple. When it is calcined in a sealed container, a series of wonderful chemical reactions will occur.

From our current understanding of chemical knowledge, sulfur trioxide is among the products after the reaction, and when sulfur trioxide dissolves in water, it turns into sulfuric acid.

Since this sulfuric acid is calcined from chlorine vitriol, it was called "chloroal vitriol oil" in ancient times. 】

People from all dynasties watched the video on the sky screen. They did not expect that the "green vitriol oil" was refined in this way, and some people had even never heard of such a thing.

But maybe many people are looking forward to its function when it is introduced on the marquee.

After all, for them, the harvest of crops is the most important.

And this "green vitriol oil" can actually be used to make fertilizer, which really surprised them!

However, those people who have seen "green vitriol oil" cannot figure out how this kind of thing can be turned into fertilizer.

However, they also organized people to experiment. After all, fertilizer is the foundation of agriculture. If their experiment is successful, I believe they will be able to make a lot of money.

Not only are they organizing people to experiment, but businesses in various industries are also experimenting.

After all, according to what Tianmu said, this sulfuric acid can not only be used to make fertilizers, but can also be used in various industries.

They also see the prospects and hope to master this technology as soon as possible?

Qin Dynasty.

Qin Shihuang read the introduction on the marquee and called the Mohist disciples again.

For Qin Shihuang, only the Mohist disciples could imitate the things on the sky curtain.

Moreover, after reading the introduction on the sky screen, he very much hoped that Da Qin could have such a thing.

After all, it is called the "Mother of Industry", and Da Qin can only develop if it has it.

So he issued an order to the Mohist disciples, asking them to make the "green vitriol oil" based on the information on the Celestial Eye, so that Great Qin could have such a thing as soon as possible.

After the Mohist disciples received the order, they returned to their workplace and summoned all the Mohist disciples to discuss how to make this "green vitriol oil".

After all, this is something new for them.

Although their hair dropped every time, they were also obsessed with the feeling of having more knowledge in their brains.

And as they learn more and more, it becomes easier and easier to master the knowledge on the topic.

They hope that one day Da Qin will be as prosperous as the future generations on the sky.

I believe that Great Qin will be extremely powerful at that time.

Han Dynasty.

Emperor Wu of the Han Dynasty Liu Che was extremely excited when he saw the video on the sky screen.

He likes videos like this to be played on the canopy, so that his craftsmen can also have such skills after learning.

This will also make the entire Han Dynasty richer and richer in materials, allowing more people to have skills.

This not only increased national power, but also improved the military strength of the Han Dynasty. Just like after he learned how to make gunpowder on Tianmu, he used it in his army.

Although the way they used it was relatively crude, it also greatly improved their chances of winning in the war with the Huns!

And now the sky screen has introduced how to make this "green vitriol oil", which will also allow the big man to have this kind of thing, and he can even research more things based on this.

After all, according to what is said on the sky screen, this kind of thing can be used to make fertilizers, medicines, pigments, detergents, etc.

So Liu Che, Emperor Wu of the Han Dynasty, issued an order to the craftsmen to make equipment for refining "green vitriol oil" according to what was said on the sky screen.

After the craftsmen received the order, they quickly took action.

Since the marquee appeared in the sky, their lives have changed decisively.

They were unimportant before, but now they have become guests of various departments in the imperial court, and are even asked by the emperor to make various things from time to time.

This has greatly improved their status and allowed them to display their talents on a larger platform.

And as they made one object after another according to the canopy, the big man became more prosperous, which also made them feel full of accomplishment.

And now His Majesty asked them to make the "green vitriol oil" mentioned on the canopy, and they began to take action.

After all, the instructions on how to make "Green Sail Oil" are very clear on the marquee, they just need to follow the steps to make it.

As they began to take action, countless merchants among the Han people began to look forward to it.

After all, according to what is said on the sky screen, this "green vitriol oil" has many functions.

If they can buy the "green vitriol oil" produced by the imperial court, then they can also give you tips on the topic and develop more possibilities!

Three Kingdoms period.

When Cao Cao saw the video on the canopy, he quickly asked someone to make it according to the prompts on the canopy.

With the emergence of Tianmu, the Three Kingdoms are no longer the original Three Kingdoms.

Because of the purchase of the books on the canopy and Zhuge Liang's blessing, the Shu Han's development had already surpassed that of Wei and Soochow.

If he doesn't work hard to catch up, I'm afraid Wei will not have the last laugh.

And seeing that Shu Han's economy becoming more and more developed, it was simply more uncomfortable than killing him.

After the craftsmen in Wei heard Cao Cao's instructions, they quickly took action.

For them, Cao Cao's orders were imperial edicts, and if they did not obey them, they would be in trouble.

Moreover, Cao Cao was also very generous with his actions. After they really fulfilled their requirements, he rewarded them very much, which made them all like this kind of monarch very much.

And now all the steps for making "green vitriol oil" are given on the screen. If they can't explain it, they will probably make people laugh.

So they quickly took action and made various equipment based on the explanations on the marquee.

And they searched for raw materials for refining "green vitriol oil" all over the country, and then started making it.

After their efforts, they finally completed their mission and produced "green vitriol oil" in their era, completely one step ahead of the Shu Kingdom.

This made Cao Cao very happy. After all, this not only gained face, but also allowed his country to develop faster.
