I was watching short videos and was seen by ancient people

Chapter 254 Essential for Time Travel—Sulfuric Acid ()

Sui Dynasty.

Yang Guang looked at the video on the marquee, and he was extremely surprised. After all, he was a person doing big projects, so how could he lack such materials?

And according to the prompts on the sky screen, after the "green vitriol oil" is refined, it can be used in a wide range of applications. Isn't this exactly what he needs in the Sui Dynasty?

And he raised so many craftsmen outside Luoyang City, wasn't it just to let them copy the technology mentioned on the canopy?

And there is enough land outside Luoyang City to build such a workshop.

Yang Guang believes that with more and more attacks and defenses outside Luoyang City, he may be able to build more and more large projects.

Sooner or later, he will surpass Qin Shihuang and become the true emperor of China through the ages.

After the craftsmen outside Luoyang City received the order, they quickly took action.

They knew that if their Majesty hesitated even a little while being infected, they would face imprisonment.

They are lucky to be able to survive outside Luoyang City, so how dare they take risks so easily.

In order to enable themselves to survive, they acted quickly according to the method Tianmushan said.

Tang Dynasty.

Li Shimin was very happy when he saw the video on the marquee.

This is not only because the Tang Dynasty had already conquered Goguryeo before the Chinese New Year, but also because with the migration of the people, the homeland of Goguryeo gradually became more prosperous.

The survivors of Goguryeo slowly adapted to the increasingly prosperous Tang Dynasty, and gradually recognized their new identities.

After all, for people like them, life is better there, and their homes are there.

And those students who passed the imperial examination were very happy when they saw that the people under their rule were getting richer and richer.

After all, this is political achievement, and it is also the basis for their future promotion and wealth.

Moreover, they are officials here, and His Majesty is watching over them. As long as they make achievements, they believe they will get the rewards they deserve.

And the facts turned out to be what they thought. As they slowly made their achievements, Li Shimin also gave them the rewards they deserved.

Li Shimin was also very happy that the method of refining "green vitriol oil" in Tianmu came from the Tang Dynasty.

After all, this was the achievement of their Tang Dynasty, so being announced on the sky screen made him feel happy.

Not only that, every time there is an additional substance in his world, many industries will be created, the people will become richer, and the Tang Dynasty will become more powerful.

Moreover, the green vitriol oil produced not only has the effects mentioned on the canopy, but can also be used in war.

When a war breaks out, throwing this kind of thing at the enemy will be very lethal and will make the enemy who is willing to resist give up resistance.

Song.

Zhao Zhen was very surprised when he saw the video on the sky screen.

Although he had long heard that the refining method of "green vitriol oil" came from the Tang Dynasty, it was not as detailed as what was said on the sky screen.

What surprised him even more was that Tianmu gave them the direction for using green vitriol oil, so that they could develop it specifically according to the direction Tianmu said.

What he is particularly looking forward to is how to use this thing to make fertilizer.

After all, no matter which dynasty you are in, food is the foundation of everything.

Without food, no matter how prosperous the Song Dynasty was, it would be just a flash in the pan.

Moreover, green vitriol oil can not only be used to make fertilizers, but can also be used in other fields, gradually enriching the materials of the Song Dynasty.

This is not to say that he has seen the results, but because every time such a video appears on the screen, there will be many businesses in the Song Dynasty to produce what you said on the screen. Although the things they made were not as good as what was said on the canopy, they were still very advanced for them.

In order to enrich the materials of the Song Dynasty, Zhao Zhen issued an order to the craftsmen of the Ministry of War to refine more "green vitriol oil" and supply it to merchants across the country so that they could study how to use it.

In another period of the Song Dynasty, Shen Kuo saw the video on the sky screen and nodded with great relief.

After all, the method of making green vitriol oil is exactly as described on the canopy, and it can be applied in many fields.

It's just that how the future generations on the sky made fertilizer also puzzled him. After all, this is a wisdom that has not existed since ancient times.

From ancient times to the present, more people have used manure to accumulate fertilizers. How could it be made with the "green vitriol oil" as mentioned on the canopy.

He is also looking forward to the next video on Tianmu, hoping that Tianmu can tell him how to use "green vitriol oil" to make fertilizer.

If fertilizer could really be produced, the Song Dynasty would no longer have to worry about food.

It can also allow those poor lands to grow more food.

tomorrow.

After Zhu Yuanzhang saw the video on the sky screen, he also paid attention to it.

He comes from a commoner background and deeply understands the significance of fertilizer to farmers.

For farmers of their time, only when the fields have fertilizer can they be highly productive, and only when the crops are highly productive can they have enough to eat.

The fertilizers they use now are generally all kinds of farm manure.

But now the sky screen actually told him that it was not just farm rice, but there were other ways to increase grain yields. How could Zhu Yuanzhang not pay attention to this?

In order to make such fertilizer, Zhu Yuanzhang gave orders to the craftsmen to make more "green vitriol oil".

And asked them to do more experiments. How can the experiments produce the fertilizer mentioned on the marquee?

At the same time, Zhu Yuanzhang is also looking forward to a video on how to make fertilizer.

In that case, the people of his Ming Dynasty will no longer go hungry, and he will no longer worry about the country's lack of food.

Not only Zhu Yuanzhang expected this, but Zhu Youjian in another time and space also expected this.

The era he lived in was a period of high incidence of various disasters. People faced various disasters and could not even eat.

Later, although in their era, according to the video on the marquee, they planted high-yield crops of sweet potatoes.

Although the sweet potato tastes sweet, it feels a little bloated in the stomach.

Compared with other cereals, it cannot be used as a real staple food.

And judging from what is said on the sky screen, the thick grain is very high-yielding, presumably because of the use of various fertilizers.

In order to make grains available to the people, Zhu Youjian also issued an order to ask craftsmen across the country to study how to use green vitriol oil and how to make fertilizer.

But no matter how they tried, they couldn't find the fertilizer mentioned on the sky screen.

They can only pray like Zhu Yuanzhang that Tianmu can publish a video on making fertilizer.

That way, they can have enough to eat in this era of frequent disasters.
