Sui Dynasty.

Yang Guang looked at the video on the canopy, and he was also very surprised, after all, he was a person who did big projects, how could he lack this material?

And according to the hints on the canopy, after this "green alum oil" is refined, it can be used in a wide range of places, isn't this exactly what he needs in Dasui?

And he raised so many craftsmen outside Luoyang City, didn't he just 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 as there are more and more attacks and defenses outside Luoyang, there will be more and more large projects that he can build.

Sooner or later, he will surpass the Qin Shi Huang and become the real emperor of China.

After the craftsmen outside Luoyang City received the order, they also hurried into action.

They knew that their majesty, if they hesitated to be infected, they would be imprisoned.

They were fortunate to be able to survive outside this Luoyang City, how dare they take risks easily.

In order to keep themselves alive, they hurriedly took action according to the method that Tianmu Mountain said.

Tang dynasty.

Li Shimin saw the video on the canopy, and he was very happy.

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

Those remnants of Goguryeo slowly adapted to the increasingly prosperous Tang Dynasty, and gradually recognized their new identity.

After all, for them, the people live better there, and there is their homeland.

And those students who were admitted to the imperial examination, they watched the people under their rule get richer and richer, and they were very happy in their hearts.

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

And they are officials here, but His Majesty is watching them, as long as they make achievements, I believe that they can get their due rewards.

And the facts are as they thought, as they slowly made their own achievements, Li Shimin also gave them the rewards they deserved.

And for the method of refining "green alum oil" on the canopy turned out to be from his Datang, Li Shimin was also very happy in his heart.

After all, this is the result of their Datang, and being announced on the canopy in this way also makes his face shine.

Not only that, every time there is one more substance in his world, it will create a lot of industries, which will also make those people richer, and will also make Datang more powerful.

Moreover, the alum oil produced is not only the effect described on the canopy, but can also be applied to war.

In the event of war, throwing this kind of thing at the enemy is also very lethal, and it will also make the enemy who has the heart to resist give up resistance.

Song dynasty.

Zhao Zhen saw the video on the canopy, and he was very surprised.

Although he had long heard that the refining method of "green alum oil" came from the Tang Dynasty, it was not as detailed as it was said in the canopy.

What surprised him even more was that Tianmu gave them the direction of using alum oil, so that they could also develop it according to the direction Tianmu said.

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

After all, no matter what dynasty it is, food is the foundation of everything.

If there is no food, no matter how prosperous the Great Song Dynasty is, it will only be a flash in the pan.

And alum oil can not only be used to make fertilizer, but also can be applied to other fields, so that the substance of the Great Song Dynasty is gradually enriched.

This is not to say that he has seen the results, but because whenever such a video appears on the canopy, he will have many merchants in the Song Dynasty to make it for you as stated on the canopy.

Although the things they made were not as good as they said in the canopy, they were still very advanced for them.

In order to make the materials of the Great Song Dynasty more abundant, Zhao Zhen issued an order to the craftsmen of the Ministry of War, asking them to refine more "green alum oil" and supply it to the merchants of the whole country, so that they could study how to use it.

In the Song Dynasty in another period, Shen Kuo saw the video on the canopy, and he nodded very gratefully.

After all, the production method of this alum oil is really as mentioned in the canopy, and it can be applied in many fields.

It's just that the future generations on the canopy don't understand how to make fertilizer, after all, this is wisdom that has not been seen since ancient times.

From ancient times to the present, more manure is used to accumulate fertilizer, how can it be made with "green alum oil" as stated in the canopy.

He is also looking forward to the video behind the canopy, hoping that the canopy will show him how to make fertilizer from "alum oil".

If they can really make fertilizer, then they will no longer have to worry about food.

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

Ming dynasty.

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

He was born in the common people and knew the significance of fertilizer to farmers.

For the peasants of their time, the fields could only be productive when they had fertilizer, and they could have enough to eat after the crops were high.

And the fertilizer they use now is generally all kinds of farm manure.

And now the canopy actually told him that not only is the farmer's meal, but there are other ways to make the grain high, how can Zhu Yuanzhang not pay attention to this.

In order to make such fertilizer, Zhu Yuanzhang issued an order to the craftsmen to make more "green alum oil".

And let them do more experiments, how can the experiment be able to make the fertilizer mentioned in the canopy?

At the same time, Zhu Yuanzhang is also looking forward to it, hoping that this canopy will be able to release a video on how to make fertilizer.

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

Not only Zhu Yuanzhang is looking forward to this, but Zhu Youzhen in another time and space is also looking forward to this.

He lived in a time when there was a high incidence of various disasters, and the people could not even eat in the face of various disasters.

Later, although they were in this era, according to the video on the canopy, those high-yielding crops of sweet potatoes were planted.

Although the sweet potato tastes sweet, it is a little swollen in the stomach.

Compared to other whole grains, it cannot be used as a real staple food.

And looking at the canopy, the thick grain is very high-yielding, and I think it is the use of various fertilizers.

In order to allow the people to eat the whole grains, Zhu Youzhen also issued an order for craftsmen across the country to study how to use alum oil and how to make fertilizer.

However, no matter how much they experimented, they were unable to find the fertilizer mentioned on the canopy.

They can only be like Zhu Yuanzhang, praying that Tianmu can release a video of making fertilizer.

In that way, they can also eat well in this era of frequent disasters.
