After a busy week, Roland built a new chemical factory next to the Chishui River, which at first glance looked like a convenient market due to the toxicity of nitrogen oxides, with unenclosed walls and wooden ceilings, a gap about one floor in between, excellent ventilation, and of course the same temperature as outside.

The new oxygen and nitrogen synthesis unit has begun 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 electric arc when interwoven into a network, and the nearly two-meter-high reactor can be converted into nitrogen dioxide in only half an hour after the reactor is filled with raw materials in proportion, and the nitric acid is introduced into the water.

The nitrogen and hydrogen ammonia synthesis equipment is also in full swing - because the output of liquid nitrogen separated by cooling is much greater than that of liquid oxygen, this part of the extra nitrogen can be used for ammonia production. Naturally, Roland would not abandon the conventional industrial method of nitric acid, and according to the two-legged walking scheme, each additional nitric acid production line could provide him with more chemical explosives.

According to the test of the white paper's ability, it was found that she could indeed accelerate the reaction of nitrogen and hydrogen when heated, and it was so fast that it seemed to skip the process and show the results directly. The disadvantage is that he still can't control the release of mana well, and he is still underage, so that the already small amount of mana is quickly consumed.

However, this shortcoming can be improved with continuous practice, and according to Wendy, the little girl's progress is very fast, and in about a week, she will be able to maintain the effect of her abilities at a fixed level.

With these two lines, combined with a steady production of nitrified* glycerin, smokeless gunpowder close to modern levels has also been settled. The next step was to design a new burst firearm and put it into production as soon as possible.

Roland was pondering his next weapon when the guard entered the office and reported to him, "Mr. Flynn Silt and his father, Sir Silt, want to see you, and are now waiting in the drawing-room. ”

"Feilin?" he thought for a moment, wasn't that the former First Knight of the Western Realm Dawn and Morning Light? His people should all stay in Changge Fortress, why did they suddenly come to the border town?"

"Mr. Filin said it had something to do with witches, and asked me to give this to you," the guard handed over a delicate piece of parchment, and saw that the pattern on it was the "treasure map" drawn before the dawn of dawn, but compared to the rough sketch, the graphic lines on the scroll seemed to be printed.

Roland suddenly remembered that Filin had said that the map was from the family's inheritance four hundred years ago, and that it was through the markings on the map that Lightning found the stone tower where Agatha was hiding.

He was immediately 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 went to the meeting 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 were wet marks on their shoulders, and beads of sweat were already on the old man's forehead. He couldn't help but laugh, "If you feel hot, you can take off your coat." There is heating in the castle, which is much warmer than outside, so be careful not to get stuffy. ”

"Warm ...... Angry?" Filmin was stunned.

"A new kind of heating device, much better than a fireplace," Roland didn't explain too much, but turned the subject to the purpose of the other party's trip, "I heard you're here for witches?"

"Yes, Your Highness," dawn nodded quickly, "I met a blue-haired woman at the convenience market......" he briefly recounted his experiences these days, "After returning to the family domain, my father told me the origin of the family, so I think she may be a witch." ”

"I see," after listening to the other party's story, Roland was surprised, he didn't expect that the Agatha family would have ordinary people survive, and it has continued to this day. "There is such a witch in Frontier Town, and she is indeed called Agatha. ”

Sir Silt stood up excitedly, "Can I ask Your Highness—"

"Let you meet?" Roland smiled and nodded, "Of course, she should be on her way back to the castle." Also, considering that she is a witch, I think it would be better for you to take off the Divine Punishment Stone from her body, which is also a basic etiquette for her. ”

"Ah, you're right. Sir hurriedly took the stone from his underwear pocket and placed it on the side of the long table.

"Tachira didn't have this kind of etiquette more than four hundred years ago, and they weren't hunted like animals by the Church," a nightingale whispered, "and for Agatha, this thing was just research material. ”

"Then you can tell if what they say is true," Roland chuckled as he covered his mouth.

Then he felt the nightingale pinch his neck.

"Liars. ”

......

"Is there anything you called me back?" said Agatha as she pushed open the door to the meeting room and said with a stumbling face, "The battle of the divine will is about to begin, and I should seize every breath to produce a confrontation...... "Probably seeing an outsider, she swallowed the word devil," and if there is nothing important, just tell me. ”

Probably because of working with the chief alchemist, she also spoke in a tone with a hint of Kaimo Stoil's style, and this spirit of dedicating every minute and every second to the production of the frontier town made Roland, as the owner of the town, feel a little weak. He cleared his throat, "Ahem, this matter is still quite important. Do you remember that four hundred years ago, when Tachila was about to fall, a team of servants separated from you and followed the army to the south of the Desperate Mountains?"

"It seems like an impression," Agatha lifted her snowflake-stained hood and raised her blue hair, "but what is the important thing? It's been so long. ”

When she revealed her true face, Filin and Sir took a cool breath in unison, and the latter knelt down on one knee directly towards her, "You are indeed Lord Agatha!"

"Are you ......?" said Agatha with a frown.

"I am a descendant of Caag, do you remember that name?" asked Sir looking up expectantly.

"Kag...... Of course, I took the name," she shrugged, "I have purchased two mortal servants, one named Kraft to serve as the head of the family guard, and the other Kag to take over the position of steward. Speaking of this, she paused slightly, "So, you are the descendant of the butler who sneaked away halfway with the magic stone and the test record?"

"What, slip ...... Let's go?" Jazz's eyes widened, "No, he-"

"Let's go," Agatha's face sank, "I don't want to see you again. ”
