According to the local literature, the most important link in the large-scale manufacturing of nitrification* glycerin is to control the temperature, and the large amount of exotherm during the reaction is very easy to make sensitive explosives explode.As long as the temperature of the large reaction vessel is constant, the nitro-glycerin can be safely produced in batches.

Laboratory equipment can be used to cool the ice, to the large-scale production and use of ice is a little powerless - the heat absorption effect of the ice water mixture is limited, the cooling speed is slow when a lot of heat, their own consumption is fast, and the production is also very troublesome.The ice coffin of Agersha can easily produce a low temperature of minus nearly Baidu, which is undoubtedly an excellent guarantee for cooling the container.

Roland did not know that these news was unreliable, but it did not prevent him from trying it one by one.Even if an accident occurs, Nanawa is the last insurance.

Back in the office, he wrote a letter of introduction to his personal guard, who took Agratha to the chemistry lab, and sent the letter to Kemo Squeer.

In the letter, in addition to introducing the ability of Ai Gesha, he also fabricated a noble identity from the upper class, but accidentally settled into this aristocratic status, so that the alchemist to temper his temper, treat the witch who can bring great help to the chemical experiment.After the guard left, Roland was still a little relieved, Kemo was a straight-tempered, and Egsha was a high-minded old witch, hoping that they would not quarrel.

Just as he was wondering if he would go to the lab in person, the scroll pushed the door open and walked in.

“Your Highness, the results of the second batch of educational universalization assessments came out,” she said with a smile in the corner of her eye, “this time there were seven hundred and sixty-two qualified people, half of whom were adults.”

“So much?”Roland was pleased.Compared with the first batch of more than 50 children from Karl College, the graduation of half of the adults means that evening training has achieved results, and at the same time, it has verified the feasibility of a series of teaching programs formulated by the Ministry of Education for large progress differences and different learning time.

“Yes, you have been promoting universal education for half a year, and these students are generally under the age of twenty-five, and it is not too difficult to master basic reading and writing.”

Probably related to the text itself, the words in Chinese are definitely not so fast, Roland thought, although he always felt that this earthworm-like text is more awkward.

When he began to implement universal education, he could do no bottom of his mind - after all, this kind of thing was still the first time in the gray castle, and there was no precedent to follow.In accordance with the principles of encouragement and subsidies, he consulted with the books for a long time, and developed a set of education programs that opened classes for minors and workers' classes at night, supplemented by a series of encouraging policies to induce workers to study.

Of course, all this is inseparable from the specific implementer, the book's due diligence management.

“You’ve worked hard,” Roland nodded.

“It is my pleasure to serve you, Your Highness.”She leaned slightly.

As the oldest witch in the League of Witches, Roland could hardly compare her to a little girl like Anna and Lightning - the book always gave him a sense of urgency, clear, and able to listen quietly to his own thoughts when discussing the problem, and pointed out his mistakes directly, and sometimes he even gave birth to a feeling of his younger generation in front of the other party.

She was born to be a teacher.

Roland smiled and shook his head, putting those thoughts aside.

In short, a new batch of new forces has been added, and some long-prepared factories can finally start.

“Please help me call Barov,” he exclaimed.

...

The town hall manager soon arrived at the castle.Since the beginning of the construction of the city, his workload has increased day by day, and the blank areas on his forehead have increased more and more, and even with wrinkles, he has increased several.But the face can not see the fatigue and sleep, but the spirit is getting better and better.

“Your Highness, are you looking for me to recruit for work?”

The other side probably also knew the news of a group of new graduates in the town and took the initiative to ask.

“Yes,” Roland nodded, “that Tiffany cannot harass the West while this year’s evil moon is in advance, and I want to expand the size of the army in the border town to cope with the war of the coming year, while expanding the number of existing factories.”

“And the town hall,” he quickly added, “after the city is built, your territory will be five to six times the current, and the town hall staff will have to expand to the corresponding size in order to manage such a wide land.”

"Don't worry," laughed the prince, "and won't forget you."He drew out the sheet of paper and wrote, "In the new 700-year graduation, the town hall provides 20% of the positions, the acid factory is divided into 40%, and the remaining people are absorbed by the steam engine factory and the bicycle factory, of which the bicycle factory needs at least 100 people."The remuneration is set according to the previous standard, and the acid factory can be slightly improved to fill the required number as soon as possible.”

As for the soap factory and the perfume factory, the main work is done by the witch, and the ordinary person only repeats the simple operation of a few steps, and can be competent without literacy, so it is not included.

Roland believes that education can not only improve a person's knowledge and vision, but also improve his sense of responsibility and sociality, the meaning of enlightenment is this.This is why the higher factories require a large number of people with primary education – a worker who opens up social attributes, who knows more about the importance of collaboration, altruism, and self-consciousness than the illiterate.This is essential for the delicate work of complex and numerous processes.

“Yes, Your Highness.”Barov replied, “How many people do the army need to be expanded?”

“At least a thousand people are open to newly promoted civilians and refugees from the East,” Roland said, “and as before, a notice was issued by the City Hall, and the First Army was responsible for reviewing and recruiting.”

“One... a thousand?”Barov said, “This is equivalent to the sum of the number of the number of the First Army at present, His Highness.”If they are equipped with supplies and weapons according to the specifications of the First Army, the cost is not low.”

"I've thought about it, so I'll do it."

Now that he knows the crisis of the devil's invasion, he naturally can no longer be as trolling as before.In addition to the integration of the whole of the West into its rule, the first thing to do next spring is to completely defeat Tifeko.As long as this regime is eliminated and this tit-for-tat regime is eliminated, even if it does not occupy other areas, the new city of the West will become a veritable “king capital”.At that time, whether it is expanding the population or promoting trade, it will be free to do so, rather than being so limited everywhere.

However, these plans do not need to be disclosed to Barov for the time being, he only needs to arrange financial distribution and distribution of materials for himself.

After the head of the town hall left, the guard brought a new message.

Marguery's caravan has arrived.
