After a week of hard work, Roland built a new chemical factory next to the Redwater River. Taking into account the toxicity of nitrogen oxides, the factory looked like a convenience market at first glance. The walls and wooden ceiling were not enclosed, leaving a one-story gap in the middle. The ventilation was excellent, and of course, the temperature was no different from outside.
The new oxygen and nitrogen synthesis equipment was already in operation. The instantaneous high temperature produced by the Blackfire was no different from an electric arc, and its efficiency was even higher than that of an electric arc. After the two-meter-tall reactor was filled with raw materials according to the ratio, it only took Anna a quarter of an hour to convert it into nitrogen dioxide, which was then converted into nitric acid in water.
The nitrogen and hydrogen synthesis equipment was also in full swing. Since the liquid nitrogen produced by cooling was far greater than the liquid oxygen, the excess nitrogen could be used to produce ammonia. Naturally, Roland would not abandon the conventional industrial production of nitric acid. He followed the two-legged plan. Every additional nitric acid production line would provide him with more chemicals.
Based on the tests of Paper's ability, he found that she could indeed accelerate the reaction of nitrogen and hydrogen under heat, and the speed was so fast that it seemed to skip the process and directly show the results. The drawback was that she still could not control the release of magic power well. In addition, she was still underage, so her already low magic power was quickly depleted.
However, this drawback could be improved through continuous practice. According to Vendy, the little girl was improving very quickly. In about a week, she would be able to maintain the effect of her ability at a fixed level.
With these two production lines and a stable nitroglycerin output, smokeless gunpowder, which was close to the modern level, would also be produced. The next step was to design a new continuous firing firearm and put it into production as soon as possible.
As Roland was thinking about the weapon selection, his personal guard walked into the office and reported, "Mr. Filin Schilt and his father, Sir Schilt, would like to see you. They are waiting in the reception room."
"Filin?" He thought for a moment. Wasn't that the former First Knight of the Western Region, The Light Of Dawn? His clansmen should be staying in Longsong Stronghold. Why did they suddenly come to Border Town? "Did they say why they were here?"
"Mr. Filin said that it's related to witches and asked me to give this to you," the guard handed over an exquisite piece of parchment. The pattern on it was exactly the "treasure map" drawn by The Light Of Dawn before. But compared to the rough sketch, the lines on the parchment seemed to be printed.
Roland suddenly remembered that Filin had once said that this map came from the inheritance of the family four hundred years ago, and Lightning had found the stone tower where Agatha was hiding through the marks on the map.
His interest was immediately piqued. "Go and call Miss Agatha back. She should still be in the chemistry lab. I'll see them right away. "
"Yes, Your Highness."
After the guard left, Roland rolled up the map and went to the living room.
Filin and an old man immediately stood up and bowed to him.
The Prince noticed that both of them were wearing thick leather coats and that their shoulders were wet. The old man's forehead was already covered with sweat. He couldn't help but laugh. "If you feel hot, you can take off your coat. There's heating in the castle, so the temperature is much higher than outside. Be careful not to suffocate. "
"Heating?" Filin was startled.
"It's a new type of heating equipment. It's much better than a fireplace." Roland didn't explain too much. Instead, he changed the topic to the purpose of the other party's visit. "I heard that you came for the witches?"
"Yes, Your Highness," The Light Of Dawn quickly nodded. "I met a blue-haired woman in the Convenience Market …" He briefly recounted his experience these days. "After returning to the family territory, my father told me about the origins of my family. So, I think she might be a witch."
"So that's how it is." After listening to the other party's story, Roland was greatly surprised. He didn't expect that an ordinary person from the Agatha family would actually survive and continue to this day. "There is indeed such a witch in Border Town, and her name is indeed Agatha."
Sir Schilt stood up excitedly. "Then can Your Highness please —"
"Let you meet?" Roland nodded with a smile. "Of course, she should be on her way back to the castle. In addition, considering that she is a witch, I think it's better for you to take off the God's Stone of Retaliation from your body. For her, this is also a basic etiquette. "
"Ah, you're right." Sir hurriedly took out the God's Stone from his pocket and put it on the side of the long table.
"More than four hundred years ago, the Taquila simply didn't have this kind of etiquette, and they weren't hunted like animals by the church." Nightingale whispered in his ear. "For Agatha, this thing is just a research material."
"This way, it's easier for you to judge whether what they say is true or not." Roland covered his mouth and chuckled.
Then he felt Nightingale gently pinch his neck.
"Liar."
…
"Why did you call me back?" Agatha pushed open the door of the living room and said with a face full of hesitation. "The Battle of Divine Will is about to begin, I should seize every moment to produce weapons to fight against …" Probably because she saw that there were outsiders present, she swallowed the word 'devil'. "If there's nothing important, you can ask someone to tell me."
Probably because she worked together with the Chief Alchemist, the way she spoke also had a trace of Kyle Sichi's style. Moreover, this spirit of dedicating every minute and every second to the production of Border Town made Roland, the owner of the town, feel a little guilty. He cleared his throat. "Ahem, this matter is still quite important. Do you remember that four hundred years ago, when the Taquila was about to be destroyed, there was a team of servants who separated from you and followed the main army to the south of the Impassable Mountain Range? "
"I seem to have some impression of it." Agatha took off her snow-covered hood and fluttered her beautiful blue hair. "But how important is this? It's been so long. "
When she revealed her true face, Filin and Sir simultaneously gasped. The latter directly knelt down on one knee. "You really are Lady Agatha!"
"You are …?" Agatha frowned.
"I'm the descendant of Kager. Do you still remember this name?" Sir raised his head and asked expectantly.
"Kager … of course, this name was given by me." She shrugged. "I once bought two mortal servants. One was named Kraft, and he served as the family's guard captain. The other was Kager, and he took over the position of the butler." At this point, she paused for a moment. "So, you're the descendant of the butler who sneaked away with the Magic Stones and the experiment records?"
"What, sneak … away?" Sir's eyes widened. "No, he —"
"Go." Agatha's face darkened. "I don't want to see you again."
