After a busy week, Roland built a new chemical factory next to the Chishui River. Considering the toxicity of nitrogen oxides, the factory looked like a very convenient market at first glance. There is a gap about one floor high, and the ventilation is excellent, and of course the temperature is no different from the outside.
The new oxygen and nitrogen synthesis device has been put into trial operation. The high temperature generated by the black fire is no different from the arc, and the efficiency is higher than that of the arc when it is interwoven into a network. After the nearly two-meter-high reactor is filled with raw materials in proportion, Anna only needs half a quarter of an hour to convert it into nitrogen dioxide, which is nitric acid when introduced into the water.
The nitrogen and hydrogen synthesis ammonia equipment is also in full swing - since the output of liquid nitrogen separated by cooling is far greater than that of liquid oxygen, this part of the excess nitrogen can just be used for ammonia production. Naturally, Roland would not abandon the conventional industrial production method of nitric acid. According to the plan of walking on two legs, each additional nitric acid production line would provide him with more chemistry.
According to the test of the ability of white paper, she can indeed accelerate the reaction of nitrogen and hydrogen under the condition of heating, and the speed is so fast that it seems to skip the process and present the result directly. The disadvantage is that the release of magic power is still not well controlled, and the fact that he is still underage makes the little magic power quickly consumed.
However, this shortcoming can be improved through continuous practice. According to Wendy, the little girl has made rapid progress. In about a week, she will be able to basically maintain the effect of her ability at a fixed level.
With these two production lines, coupled with stable nitroglycerin output, smokeless powder that is close to the modern level has also landed. The next step is to design a new repeater and put it into production as soon as possible.
Roland was thinking about the next weapon selection, and the guard walked into the office to report to him, "Mr. Philyn Sylt and his father, Sir Sylt, want to see you, and are now waiting in the living room."
"Fei Lin?" He thought for a moment, wasn't that the first knight in the west at dawn? His clansmen should all stay in Changge Fortress, why did they suddenly come to Border Town? "Did they say why?"
"Mr. Filmin said it had something to do with witches, and asked me to give this to you." The guard handed over a piece of delicate parchment, and the pattern on it was exactly the "treasure map" drawn before dawn, but it was more than From the rough sketch, the graphic lines on the paper roll almost seemed to be printed.
Roland suddenly remembered that Ferrin had said that this map came from the inheritance of the family four hundred years ago, and Lightning found the stone tower where Agatha was hiding through the mark on the map.
He suddenly became interested, "Go and call Miss Agatha back, she should still be in the chemistry lab. I'll go see them right away."
"Yes, Your Highness."
After the guards left, Roland rolled up the map and came to the living room.
Fei Lin 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 was a wet mark on their shoulders, among which beads of sweat had been dripping from the old man's forehead. He couldn't help laughing, "If you feel hot, you can take off your coat. There is a heating supply in the castle, which is much higher than the temperature outside, so be careful not to get stuffy."
"Warm...chi?" Fei Lin was stunned.
"A new type of heating equipment, which is much better than a fireplace," Roland didn't explain too much, but turned the subject to the purpose of the other party's visit, "I heard that you are here for witches?"
"Yes, Your Highness," Dawn and Morning Light nodded quickly, "I met a blue-haired woman at the convenience market..." He briefly recounted the experience of these days, "After returning to the family territory, my father told my family So, I think she might be a witch."
"That's it," Roland was greatly surprised after listening to the other party's story. He didn't expect that ordinary people in the Agatha family would survive, and it has continued to this day. "There is indeed such a witch in Border Town, and her name is indeed Agatha."
Sir Sylt stood up excitedly, "Then can I invite Your Highness—"
"Let you meet?" Roland nodded with a smile, "Of course, she should be on her way back to the castle. Besides, considering that she is a witch, I think it's better for you to take off the God's Stone of Retribution. , which is also a basic etiquette for her."
"Ah, you're right." Jazz hurriedly took out the divine stone from his underwear pocket and put it on the side of the long table.
"Taquila more than 400 years ago did not have such etiquette at all, and they were never hunted by the church like animals," the nightingale whispered in his ear, "For Agatha, this thing is just a research material."
"That way you can easily judge whether what they said is true," Roland covered his mouth and chuckled.
Then he felt Nightingale pinching lightly on his neck.
"fraud."
…
"What's the matter with you calling me back?" Agatha pushed open the door of the living room, and said without hesitation, "The battle of divine will is about to start. I should seize every moment of time to produce weapons against..." Probably seeing an outsider, she swallowed the word devil, "If there is nothing important, just ask someone to tell me."
Probably because of working with the chief alchemist, her tone of voice also brought a touch of Kemer Stile's style, and this spirit of dedicating every minute and every second to the production cause of Frontier Town made her As the owner of the town, Roland felt a little guilty. He cleared his throat, "Cough, this matter is quite important. Do you remember, when Taquila was about to be destroyed four hundred years ago, a team of servants separated from you first and followed the large army to the Desolate Mountains. South?"
"It seems to be a bit of an impression," Agatha lifted her snow-covered hood and raised her blue hair, "but what is this important thing? It's been so long."
When she showed her true face, Ferrin and Serena both took a breath, and the latter knelt down directly to her, "You really are Lord Agatha!"
"Are you...?" Agatha frowned.
"I am a descendant of Kaggar, do you still remember this name?" Sir raised his head and asked expectantly.
"Kag... Of course, I took the name," she shrugged, "I once purchased two mortal servants, one named Kraft, who served as the captain of the family guard, and the other, Kag, who took over. The role of housekeeper." She paused slightly when she said this, "So, you are the descendant of the housekeeper who sneaked away with magic stones and test records halfway through?"
"What, slip... away?" Sir widened his eyes. "No, he—"
"Let's go," Agatha's face sank, "I don't want to see you again."
