"Cockroach Mantis Arm: My grandparents' generation still called soap and called melanchophyllum [crying silently] [crying silently] [crying silently]. 》

The people of various dynasties only reacted when they saw this, and it turned out that this alkali was the ash of plants and trees when they made soap.

However, looking at the introduction on the canopy, they felt that something must be different.

After all, the soap they made was not the same as that of the later generations of Tianmu Mountain.

Not only are there more impurities, but the decontamination effect is not so good.

Moreover, in order to make soap, the ash of plants and trees in the vicinity has long been insufficient, and they are also eager to learn the process of making alkali again on the canopy, so that they will have no worries when making soap.

When some people saw the canopy, they actually said that alkali could make steamed bread white and sweet, so they filtered the ashes of the plants and trees many times, and then boiled the water in it for a long time before using it to make noodles.

It's just that the result is not as white and sweet as it says in the canopy.

They felt that the canopy was deceiving, after all, the alkali made from the ashes of plants and trees did not have such an effect.

At the same time, some people recalled what they had done, and he realized that this plant ash was not equal to alkali.

After the emperors of various dynasties saw the comments on the canopy, they realized the effect of this alkali, which not only made steamed buns white and sweet, but also made soap.

It's just that if there is only such a role, the person introduced in the canopy should not be praised by the imperial court.

And now that it is being praised by the court of later generations, it must have other functions.

They were looking forward to the detailed action of alkali and how to make it in detail on the canopy, so that they could make and use it.

At that time, they can also eat white and sweet steamed buns.

"Cute: I have a large alkali factory here, which has more than 10,000 employees, and they use the Hou's alkali making method, and his statue has been erected in the factory, and half of the people in the district live on this factory. 》

This......

After the people of various dynasties saw this comment, they were shocked, they did not expect that a mere method of making alkali could feed a factory.

What amazed them even more was that there were so many employees in this factory! If it is converted into a family, it is simply that there are people working in this factory in every county at this time.

If this is the case, this person needs to be praised, after all, he can be said to be the parent of more than 10,000 people.

At the same time, the people of various dynasties also slowly understood that the original factory could not only have dozens of people, or even hundreds of people, but also have such a scale.

They also hope that there will be a factory of this size in their time, so that they will also have jobs to earn money, and in order to make their families better.

The emperors of various dynasties looked at the video on the canopy, and they didn't understand that the merchants of later generations had such strength and could raise so many employees.

They still don't understand, is it possible that the court of later generations is so relieved of those merchants? Aren't you afraid that they will make trouble?

After all, at this time, they didn't dare to give those businessmen so much power, and if they were in turmoil, they were afraid that it would be very troublesome for the court to rehabilitate.

When the people of various dynasties saw the comments on the canopy, they couldn't understand the words in the sky, and they didn't expect that there would be such words in this world.

And even in the following comment, they can recognize all the words in it, but they don't know what it means when it is connected.

It's just that people with vision still recorded the formulas and words on the canopy.

They were waiting for the canopy to teach them how to make alkali, and then slowly understand the formulas and words.

At the end of the Ming Dynasty, Zhu Youzhen also recorded it, this is not because he has any vision, but because he has the habit of copying homework!

At the same time, he was also waiting for the specific meaning of these formulas and words, so that he could apply these things to his Ming Dynasty, and let his people eat white and sweet steamed buns.

And these letters on it, he has also seen it from Xu Guangqi, and knows that it is the script of a Western country.

Although he doesn't know what it means now, he believes that Xu Guangqi will definitely be able to know.

The emperors of other dynasties, they also realized the usefulness of these words and formulas, and they also had people record them, waiting for their technical officials to study them.

A little more advanced, test the chemical thermodynamics, the density of the reaction solution, and how long it takes to stir.

How to separate the products, how to industrialize purification.

How to recycle waste liquid from the perspective of environmental protection, and how much kilowatt-hour of electricity is needed per kilogram of soda ash? 》

The emperors of various dynasties saw the later generations on the canopy, and they actually took the test of this Hou's alkali method every three or five times, and they once again realized the role of these formulas.

And looking at the comments above, they also once again realized why later generations were so developed.

This is not only because of the large population of later generations, but also because they are so eager to learn, so that the lives of later generations will slowly improve.

Du Fu looked at the comments on the canopy, his heart was not comfortable, after all, the last time he saw on the canopy, he was still the one who was changed by the portraits of the students of later generations.

And now that he sees a person's portrait being altered by magic, his heart feels a little better.

And the gentlemen of the various dynasties were very annoyed when they saw the comments on the canopy.

The portrait in the textbook is not a sage, how can it be insulted like this?

If it were placed in their time, such a student would definitely be punished!

And the students of various dynasties, they saw the comments on the canopy, they looked at the gentleman in front of them, and drew according to his figure.

It's just that the drawn avatars have been polished by them, changing their outfits, making them a real woman on paper.

After they were sent out, they were watched by the students who studied together, sharing their portraits together, which also made the boring school life more joyful.
