After a busy week, Roland built a new chemical factory next to the Chishui River. Considering the toxicity of nitrogen oxides, the factory looked very much like a convenience market at first glance. The walls and wooden roof were not completely closed, leaving a gap of about one floor high for excellent ventilation. Of course, the temperature was no different from the outside.
The new oxygen and nitrogen synthesis device has started trial operation. The high temperature generated by Blackfire is no different from an electric arc, and its efficiency is higher when interwoven into a network. After the nearly two-meter-high reactor is filled with raw materials in proportion, Anna only needs half an hour to convert it into nitrogen dioxide, which becomes nitric acid when introduced into water.
The equipment for synthesizing ammonia from nitrogen and hydrogen is also in full swing—since the production of liquid nitrogen separated by cooling is far greater than that of liquid oxygen, the excess nitrogen can be used to produce ammonia. Roland naturally wouldn't abandon the conventional industrial method of nitric acid production. According to the plan of walking on two legs, each additional nitric acid production line can provide him with more chemical explosives.
According to the test of Bai Zhi's ability, she can indeed accelerate the reaction of nitrogen and hydrogen under heating, and the speed is so fast that it seems to skip the process and directly present the result. The disadvantage is that she still cannot control the release of magic power very well, and coupled with her own immaturity, the not-so-much magic power is quickly consumed.
However, this shortcoming can be improved through continuous practice. According to Wendy, the little girl is improving very quickly, and in about a week, she will be able to maintain the effect of her ability at a fixed level.
With these two production lines, coupled with a stable output of nitroglycerin, nearly modern-level smokeless gunpowder is also within reach. The next step is to design a new repeating firearm and put it into production as soon as possible.
Just as Roland was thinking about the next weapon selection, a guard walked into the office and reported to him, "Felin. Xierte and his father, Sir Xierte, want to see you and are waiting in the reception room."
“Felin?” He thought for a moment, wasn't that the former First Knight of the Western Region, Dawn Light? His clansmen should all be staying in Longsong Stronghold, how did they suddenly come to Border Town? "Did they say what it was about?"
"Mr. Felin said it was related to the witch, and asked me to give this to you," the guard handed over a delicate parchment, on which the pattern was the "treasure map" drawn by Dawn Light before, but compared to the rough sketch, the graphics and lines on the scroll were simply like they were printed.
Roland suddenly remembered that Felin had said that this map came from the family's inheritance four hundred years ago, and Lightning found Agatha's hidden stone tower through the markings on the map.
He immediately became interested, "Go and call Agatha xiaojie back, she should still be in the chemistry laboratory. I'll go see them right away."
“Yes, Your Highness.”
After the guard left, Roland rolled up the map and went to the reception room.
Felin and an old man immediately stood up and bowed to him.
The prince noticed that both of them were wearing thick leather coats, and there were patches of wetness on their shoulders. The old man's forehead was already sweating. He couldn't help but smile, "If you feel hot, you can take off your coats. The castle has heating, which is much warmer than the outside. Be careful not to get stuffy."
"Heat...ing?" Felin was stunned.
"A new type of heating equipment, much better than a fireplace," Roland didn't explain too much, but turned the topic to the purpose of their trip, "I heard you came for the witch?"
"Yes, Your Highness," Dawn Light quickly nodded, "I ran into a blue-haired woman at the convenience market..." He briefly recounted his experiences these days, "After returning to the family territory, my father told me about the family's origins, so I think she might be a witch."
"I see," after listening to the other party's story, Roland was very surprised. He didn't expect that there would be ordinary people surviving in the Agatha family, and that they would continue to this day. "There is indeed such a witch in Border Town, and her name is indeed Agatha."
Sir Xierte stood up excitedly, "Then can Your Highness—"
"Let you meet her?" Roland
He nodded with a smile, "Of course, she should be on her way back to the castle. Also, considering that she is a witch, I think you should take off the God's Punishment Stone you're wearing. This is a basic courtesy to her."
"Ah, you're right." The knight hurriedly took out the God's Stone from his underwear pocket and put it on the side of the long table.
"There was no such etiquette in Taquila more than four hundred years ago. They weren't hunted down by the church like animals," 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," Roland covered his mouth and chuckled.
Then he felt Nightingale gently pinch his neck.
"Liar."
……
"What do you want me back for?" Agatha pushed open the door of the reception room and said with displeasure, "The Battle of Divine Will is about to begin, and I should seize every moment to produce weapons to fight against... the demons," probably because she saw outsiders, she swallowed the word "demon", "If there's nothing important, just tell me."
Perhaps because she works with the Chief Alchemist, her tone of voice also has a hint of Caimo. Sitaire, and this spirit of dedicating every minute and every second to the production cause of Border Town makes Roland, the owner of the town, feel a little guilty. He cleared his throat, "Cough cough, this matter is quite important. Do you remember that when Taquila was about to be destroyed four hundred years ago, a team of servants separated from you and followed the main force south of the Impassable Mountain Range?"
"I seem to have some impression," Agatha took off the snow-covered hood and raised a head of blue hair, "But what important thing is this? It's been so long."
When she revealed her true face, Felin and the knight gasped. The latter knelt down on one knee directly to her, "You are indeed Lady Agatha!"
"You are...?" Agatha frowned.
"I am a descendant of Kage. Do you still remember this name?" the knight asked, looking up expectantly.
"Kage... of course, I gave him that name," she shrugged, "I once bought two mortal servants, one named Caffle, who served as the family's guard captain, and the other was Kage, who took over as butler." Speaking of which, she paused slightly, "So, you are the descendant of the butler who secretly ran away with the magic stone and experiment records?"
"What, ran... away?" The knight's eyes widened, "No, he—"
"Leave," Agatha's face darkened, "I don't want to see you again."
