"Don't have money to buy food?"

Alan was stunned, this is an area he doesn't care much about, because of the emergence of transparent glass, Tomorrow Town has monopolized the national glass market, a large number of variegated glass merchants are forced to jump into the river, and every day there is a steady stream of wealth into Allen's pocket, making Allen think that Tomorrow Town will never be poor again.

"Of course, the iron ore and other minerals we buy now are tons and tons, and you don't look at how many sailboats are shipped to Tomorrowtown every day."

Windsor's cattail swung straight and rolled her eyes at him.

Alan coughed a few times, still without the idea of restraint, "Since the money is not enough to make money, let's develop new products." ”

"What commodity?"

"Flat glass mirrors, there are no such pure products on the market now, they must be a big seller."

Alan got up, took the confused Windsor downstairs, and went to the Ministry of Resources to ask the orcs, and learned that Tomorrowtown already has a variety of minerals, including several tons of silver.

Due to the development of chemistry class, the orcs who have already gone to school know that the world is full of atoms, and humans are also composed of countless atoms.

After all, with physics and biology in front of them, their worldview has been subverted many times, and they gradually adapt to the new knowledge that Allen brought with them.

When he arrives at the glassworks, Buck, the master of glass, immediately puts down his work and lets the apprentices take over his glassblowing, and then comes to Alan with a cheerful tail.

Buck saw Alan and greeted him silly, "Lord Alan, the weather is nice today." ”

Alan glanced at the column of smoke rising high in the distance, the air pollution is not too serious now, at least it will be a few years before the factories are everywhere before it affects the color of the sky.

After talking a few words about the weather, and last night's meal, Windsor was a little impatient, and Alan cut to the point.

"This time we are about to start making flat mirrors, making mirrors is indispensable for tin bath floating, and silver plating liquid also requires a lot of chemical knowledge, have you studied chemistry textbooks well recently?"

Alan casually mentioned a chemistry textbook, and Buck from Southbank Town was stunned and scratched his head unconsciously: "Lord Allen, I was dizzy from reading that book. ”

"Dizziness also has to be read, if you don't know enough, you can let your apprentice replace you, and I will promote whoever does a good job." Eren knew that chemistry would give orcs a headache, but he still demanded knowledge from them.

Buck could only grimace as he listened to Alan talk about how to make silver plating.

"The output of this silver plating solution is not high, and it is currently prepared by the orc laboratory, using silver nitrate to dissolve water, adding ammonia and sodium hydroxide to dilute it into silver hydroxide according to the ...... of double salt."

A long list of chemical terms popped out of Alan's mouth, making Buck feel dizzy, and his mind thought of silver, nitrate, sodium, and other things at the same time.

These things are not simple, and each term of chemistry involves a lot of production chains, such as how to make sodium hydroxide, how to make ammonia, and how to make silver nitrate.

Without understanding these things, it is impossible to make silver plating.

Windsor, who was standing behind him, erected straight cat ears and asked, "Young Master Allen, is there nothing else except the chemical silver plating method?" ”

"Of course there is, such as tin amalgam combined with mercury and tin, but mercury is toxic to the human body, and we are now using chemical silver plating, which is safer."

"Mercury is toxic?" Windsor had already put up the tail of the question mark, the pink blue cat's ears moved slightly, and the big eyes were full of curiosity.

"Methylmercury is easy to act in lipids, it is not easy to be broken down by the human body, and its carbon-mercury bond is not easy to cut, it is a high nerve agent, you know the nerves, it is the nerves in your human body......"

Alan saw Windsor shrink his cat's ears, and comforted: "The mercury vapor that evaporates at room temperature is highly toxic, but the amount of mercury in the body of the organism that is usually taken is very small, and a trace amount of mercury will be fine, it needs a long time to accumulate before it can manifest, don't worry too much." ”

"Lord Allen, what are you talking about, I'm so dizzy."

Buck on the side was dizzy, feeling his brain trembling and confused.

Who am I, where am I, and what am I doing...... Buck shook his head, not listening to the complex terms that popped out of Alan's mouth.

"Study more, these textbooks have mentioned it." Windsor felt unhappy for Alan when he saw that the glass director was so useless.

She turned to the group of glass-making apprentices and asked, "Do any of you understand, and if you think you understand, you can join the plate mirror making group." ”

The little slaves showed idiot eyes one after another, and shook their heads stupidly: "Report to my lord, we have just begun to learn the common script of the Lionheart Kingdom, and we can't read chemistry books." ”

"Oh forget, the town has just started universal education."

Windsor retreated in frustration, forgetting that many of the workers in the town were slaves, and they had no education before, and even if the town opened up opportunities for adult slaves to learn, it would be difficult for them to learn well.

Recently, the school's teaching team has expanded, and the teachers in the primary school are basically "little teachers", and adult teachers have been sent to various construction sites to carry out open-air teaching with the latest masterpiece of the blacksmith shop, the "portable blackboard", and promote education to the slave class.

At this juncture, the slaves were not like slaves, but more like free people, except that they had no wages and no comfortable cement houses, and their rights were not much different from those of free people.

There are more and more adult teachers at the grassroots level, and there are even elementary school students who go to the construction site to teach people.

A small number of slaves could understand it at a point, and most slaves had to speak back and forth to understand.

Unless Alan himself taught, Windsor glanced at Alan secretly, which felt unlikely.

Now Alan teaches chemistry, physics, and biology every day, which takes up half a day, and it is impossible to extend his classroom to slaves who have no foundation.

Allen's eloquence is the most awesome personal talent she has ever seen, as long as she opens her mouth to talk for a few minutes, no matter how difficult the problem is, it is easy to sort out the difficult questions, and she remembers it very well, and it is difficult to forget what Allen has taught.

After a while, Alan went to the chemistry lab and formed a group of orcs to make the chemicals needed for plate glass.

Most of the former slave members of the experimental group have been eliminated and sent off by Allen to study chemistry or work as drudgers in the gunpowder factory.

In addition, he introduced a group of students who were more proficient in chemistry to the chemistry laboratory to increase the production efficiency of the chemistry laboratory.

After a long day's work, a flat mirror with a very small production volume was finally born.

At the same time, Marianne, Marhi and other businesswomen wagged their cat's tails and laughed as they invited merchants to Tomorrowtown to participate in the auction of new goods.
