According to the literature on the street, the most important part of large-scale production of nitroglycerin was temperature control. The large amount of heat released during the reaction could easily cause sensitive explosives to explode. As long as the temperature of the large reaction vessel was kept constant, it could safely produce nitroglycerin in batches.
During the laboratory test, ice could be used to cool it down, but when it came to large-scale production, it was a bit inadequate. The heat absorption effect of the ice-water mixture was limited, and when a large amount of heat was released, the cooling rate was slow, and it consumed itself quickly, making it very troublesome. But Agatha's ice coffin could easily produce a temperature of nearly a hundred degrees below zero, which was undoubtedly an excellent guarantee for cooling the vessel.
Roland didn't know whether this information was reliable or not, but it didn't prevent him from testing it one by one. Even if there was an accident, there was still Nana as the last insurance.
Back to the office, he wrote a letter of introduction and gave it to the guard, asking the latter to take Agatha to the chemistry laboratory and deliver the letter to Kyle Sichi.
In the letter, in addition to introducing Agatha's ability, he also fabricated a noble identity that she was born in an upper-class family, but accidentally drifted to this place, so that the alchemist could control his temper and treat this witch who could bring great help to the chemistry experiment. After the guard left, Roland was still a little worried. Kyle was a straightforward person, and Agatha was an ancient witch who thought highly of herself, so he hoped that they wouldn't quarrel.
Just as he was thinking about whether he should go to the laboratory later, Scroll opened the door and walked in.
"Your Royal Highness, the results of the second batch of the universal education assessment have come out," she said with a smile, "This time there are a total of 762 people who passed, half of them are adults."
"So many?" Roland was happy. Compared with the first batch of more than 50 children from Carr Academy, this time half of the adults graduated, which meant that the evening training had achieved results, and also verified the feasibility of a series of teaching programs formulated by the Ministry of Education for the large difference in progress, different study times, and other situations.
"Yes, you have been promoting universal education for almost half a year, and this batch of students are generally under 25 years old, so mastering the basic reading and writing is not too difficult."
It probably had something to do with the writing itself. If it were Chinese, it would not have been so fast. Roland thought, although he always felt that this earthworm-like writing was as awkward as it could be.
He had no idea how far he could go when he started to implement universal education. After all, this was the first time something like this had happened in Graycastle. There were no precedents. In accordance with the principle of encouragement and subsidies, he discussed with Scroll for a long time, and developed an education program that would set up classes for minors during the day and classes for workers at night, supplemented by a series of incentive policies to entice workers to come and learn. So far, the effect was actually quite good.
Of course, all of this was inseparable from Scroll's responsible management.
"You've worked hard." Roland nodded.
"It is my honor to serve you, Your Highness." She bowed slightly.
As the oldest witch in the Witch Union, it was difficult for Roland to compare her with little girls like Anna and Lightning. Scroll always gave him the feeling that she was not in a hurry, and she was always clear. When discussing problems, she would quietly listen to his ideas, but also straightforwardly point out his mistakes. Sometimes, he even felt like a junior in front of her.
Perhaps … she was born to be a teacher.
Roland smiled and shook his head, putting these thoughts aside.
In short, now that there was a new batch of fresh troops, some of the long-prepared factories could finally start operating.
"Please help me call Barov over," he said excitedly.
…
The City hall supervisor quickly rushed to the castle. Since he started building the city, his workload had increased day by day. Not only did the number of blank areas on his forehead increase, but he also had a few more wrinkles. However, he didn't look tired or sleepy at all. Instead, he looked more and more energetic.
"Your Highness, are you looking for me about the job recruitment?"
The supervisor probably knew about the new batch of graduates in Border Town, so he took the initiative to ask.
"Yes," Roland nodded. "Taking advantage of this year's early Months of Demons, Timothy can't harass the Western Region. I want to expand the size of the army in Border Town to cope with the next year's war, and at the same time, expand the number of people in the existing factories."
"And City hall," he quickly added. "After the city is built, your territory will be five to six times larger than it is now. City hall personnel will also have to be expanded to a corresponding scale to manage such a vast land."
"Rest assured," the prince smiled. "I won't forget you." He took out a piece of paper and said while writing, "Among the new batch of more than 700 graduates, the City hall will provide 20% of the jobs, the acid factory will take 40%, and the rest will be absorbed by the steam engine factory and bicycle factory. The bicycle factory needs at least 100 people. The salary will be set according to the previous standard, but the acid factory can be slightly raised to fill the required number as soon as possible. "
As for the soap factory and perfume factory, the main work was done by witches. Ordinary people only needed to repeat a few simple steps, and they didn't need to be literate to be competent, so they weren't included.
Roland believed that education could not only improve a person's knowledge and vision, but also improve his sense of responsibility and sociability. This was the significance of enlightenment. This was also why a large number of people who had received primary education were needed in advanced factories. A worker with social attributes would understand the importance of cooperation, altruism, and self-awareness better than an illiterate person. This was crucial for a complex process with many steps of fine work.
"Yes, Your Highness," Barov responded. "How many people do we need to expand the army?"
"At least a thousand people. Open the recruitment to newly promoted civilians and Eastern Region refugees," Roland ordered. "As in the past, the City hall will release a notice, and the First Army will be responsible for the review and recruitment."
"A … thousand people?" Barov was startled. "This is equivalent to the current total number of people in the First Army, Your Highness. If they are all equipped with materials and weapons according to the specifications of the First Army, the cost will not be low. "
"I've considered all these, so let's do it."
Now that he knew the crisis of the demons' invasion was imminent, he naturally couldn't plan slowly like before. In addition to bringing the entire Western Region under his rule, the first thing to do next spring was to completely defeat Timothy. As long as he eliminated this opposing regime, even if he didn't occupy other areas, the New Western Region would become a veritable "King's City". At that time, whether it was the expansion of the population or the promotion of trade, he would be able to do whatever he wanted, unlike now where he was restricted in every aspect.
However, he didn't need to disclose these plans to Barov for the time being. He only needed to arrange the financial distribution and material distribution for himself.
After the City hall supervisor left, the guard brought a piece of news.
Margaery's caravan had arrived.
