According to the literature of the stalls, the most important part of the large-scale production of nitrate* glycerin is temperature control, and the large amount of heat released during the reaction is very easy to cause the explosion of sensitive explosives. As long as the temperature of the large reaction vessel can be kept constant www.biquge.info nitrified glycerol can be safely produced in batches.

Ice cubes can be used to cool down in the laboratory trial, but it is a bit powerless to use ice cubes in large-scale production - the endothermic effect of ice-water mixture is limited, and the cooling speed is slow when encountering a large amount of exothermics, and its own consumption is fast, and it is also very troublesome to prepare. And Agatha's ice coffin can easily produce a low temperature of nearly 100 degrees below zero, which is undoubtedly an excellent guarantee for cooling the container.

Roland didn't know whether these news were reliable or not, but it didn't prevent him from trying them one by one. Even in the event of an accident, there is Nanawa as a last line of insurance.

Back in his office, he wrote a letter of introduction and gave it to his guard, who took Agatha to the chemistry lab and delivered it to Camo Stow.

In the letter, in addition to introducing Agatha's abilities, he also fabricated the identity of a nobleman who was born in an upper-class family but accidentally fell here, so that the alchemist could restrain his temper and treat this witch who could bring great help to chemical experiments. After the guards were ordered to leave, Roland was still a little relieved, Kaimo was a straight-tempered person, and Agatha was an ancient witch who thought highly of herself, hoping that they would not quarrel.

Just as he wondered if he would go to the lab to see it himself, the scroll pushed open the door and walked in.

"Your Highness, the results of the second batch of education popularization assessments have come out," she said with a smile in the corner of her eyes, "this time there are a total of seven hundred and sixty-two qualified people, half of whom are adults. ”

"So much?" Roland rejoiced. Compared to the first batch of more than 50 children from Carr College, half of the adults graduated this time means that the evening training has paid off, and it also validates the feasibility of a series of teaching programs developed by the Ministry of Education in response to large differences in progress and learning time.

"Yes, you have been implementing universal education for almost half a year, and this group of students is generally under the age of 25, so it is not too difficult to master basic reading and writing. ”

Probably it has something to do with the text itself, and it is definitely not so fast when it is changed to Chinese, Roland thought, although he always felt that this earthworm-like text was as awkward as it was.

When universal education began, he didn't know how far he could go - after all, this was the first time this kind of thing had happened in the Grey Castle, and there was no precedent to follow. In accordance with the principle of encouragement and subsidy, he consulted with the book for a long time, and worked out a set of educational programs for minors during the day and workers' classes at night, supplemented by a series of encouraging policies to induce workers to come to study.

Of course, all this is inseparable from the specific implementer, the responsible management of the book.

"You've worked hard," Roland nodded.

"It is my pleasure to serve you, Your Highness. She bowed slightly.

As the oldest witch in the Witch League, it is difficult for Roland to compare her with little girls like Anna and Lightning - the book always gives him the impression of being unhurried and organized, and when discussing problems, he can listen quietly to his own ideas, but also point out his mistakes directly, and sometimes he even feels like a junior in front of the other party.

Probably...... She was born to be a teacher.

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

In short, now that a new group of new forces has been added, some factories that have been in preparation for a long time can finally start.

"Please help me get Barov here," he said with gusto.

......

The town hall steward quickly arrived at the castle. Since he started to build the city, his workload has increased day by day, and the white space on his forehead has become more and more numerous, and even the wrinkles have increased by several times. However, there was no fatigue or sleepiness on his face, and his spirit was getting better and better.

"Your Highness, you are looking for me for job recruitment?"

The other party probably also knew the news of the new batch of graduates in the town, and took the initiative to ask.

"That's right," Roland nodded, "taking advantage of the advance of this year's evil moon and the fact that Tifeko will not be able to harass the West, I will expand the army in the border towns to cope with the war in the coming year, and at the same time expand the number of people in the few factories I have." ”

"And the town hall," he hastened to add, "and your territory will be five to six times larger than it is now, and the city hall staff will have to be expanded to manage such a vast land." ”

"Don't worry," the prince smiled, "I won't forget you." He took out a piece of paper and said as he wrote, "Among the more than 700 people graduating from the new batch, the city hall will provide 20 percent of the jobs, the acid factory will be divided into 40 percent, and the rest will be absorbed by the steam engine factory and the bicycle factory, of which the bicycle factory needs at least 100 people." Salaries are set according to the previous standard, and the acid plant can increase it slightly to fill the required number of people as soon as possible. ”

As for the soap factory and the perfume factory, its main work was done by witches, and ordinary people only had to repeat a few simple steps, and they did not need to be literate to do it, so they were 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, and this is the meaning of enlightenment. This is why the high factories need a large number of primary-educated people - a worker who has opened up the social attributes, understands the importance of collaboration, altruism, and self-consciousness more than the ignorant who cannot read a large number of words. This is essential for delicate work with complex processes and many steps.

"Yes, Your Highness. Barov replied, "How many people does the army need to be expanded?"

"At least a thousand, open to recruitment to newly promoted civilians and refugees from the East," Roland commanded, "and as always, the town hall will put out the notice, and the First Army will be responsible for reviewing and recruiting." ”

"One...... A thousand?" Barov was stunned, "This is equivalent to the total number of the current First Army, Your Highness." If they were all equipped with supplies and weapons according to the specifications of the First Army, the cost would not be low. ”

"I've thought about all of this, so let's do it. ”

Now that he knew that the danger of the devil's invasion was imminent, he naturally could no longer try to do it as slowly as before. In addition to bringing the entire Western Frontier under his rule, the first thing to do when the next spring arrives is to completely defeat Tifeko. As long as this-for-tat regime is eliminated, even if other areas are not occupied, the new city of the western frontier will become a veritable "royal capital". At that time, whether it is expanding the population or promoting trade, it will be able to do it freely, and it will not be as restricted as it is now.

However, there is no need to disclose these plans to Barov for the time being, he only needs to arrange the financial distribution and material distribution for himself.

After the town hall manager left, the guards brought a new message.

Margaery's caravan arrived.
