After a busy week, Roland built a new chemical factory next to the Redwater River, considering the toxicity of nitrogen oxides, the factory at first glance looks like a very convenient market, the wall and the wooden overhead shed are not closed, there is a gap about a floor in the middle, excellent ventilation, of course, the temperature is no different from the outdoors.

The new oxygen and nitrogen synthesis devices have begun to be tested, the high temperature and arc generated by the black fire are the same, and the efficiency is higher when interwoven into a mesh than the arc, and the nearly two-meter-high reactor is filled with the raw material in proportion, Anna only needs half an hour to convert it into nitrogen dioxide, and the nitric acid is imported into the water.

The nitrogen and hydrogen-synthetic ammonia equipment is also in the intensive production - because the liquid nitrogen output separated by cooling is far greater than liquid oxygen, so this part of the excess nitrogen can be used to make ammonia.Roland naturally does not leave behind the conventional industrial system of nitric acid, according to the two-legged walk plan, every additional nitric acid production line can provide him with more chemical explosives.

According to the test of the white paper ability, she can indeed heat the nitrogen and hydrogen reaction, and the degree is as fast as skipping the process, directly showing the results.The disadvantage is that it is still unable to control the release of magic, and the fact that he is still underage, so that the magic that is not much is quickly consumed.

However, this shortcoming can be improved by continuous practice, according to Wendy, the little girl progresses rapidly, and almost another week, she can basically maintain the effect of the ability to maintain a fixed level.

With these two production lines, coupled with a stable nitrification * glycerin output, smoke-free gunpowder close to the modern level has also fallen.The next step is to design a new serial flame and put it into production as soon as possible.

Roland was thinking about the next weapon selection, and the patriarch went into the office and reported to him, "Mr. Filing Sirett and his father, Sir Sir Sir, want to see you, and are now waiting in the drawing-room."

“Flin?”He thought for a moment, isn't that the first knight of the Westland before the dawn of the morning light?His people should all stay in the long song fortress, why suddenly ran to the border town?“Did they say what was going on?”

"Mr. Filing said that it is related to the witch, and let me give this to you," said the guard, who handed me a delicate parchment, and saw that the above pattern was exactly the "treasure map" drawn before the dawn, but compared with the rough sketch, the graphic lines on the paper roll were almost like printed.

Roland suddenly remembered that Filing had said that the map was from the family's 400-year-old lineage, and that lightning had found the stone tower where Egsa was hiding through the markings on the map.

He was interested in "to call Miss Agra, she should still be in the chemistry laboratory."I'll see them right away."

“Yes, Your Highness.”

After the guard left, Roland rolled up the map and came to the living room.

Philin and the old man immediately stood up and saluted him.

The prince noticed that they were both wearing thick leather coats and a wet mark on their shoulders, and that the old man had already excreted sweat on his forehead.He couldn’t help but laugh, “If you feel hot, you can take off your coat.”There is a lot of heat in the castle, much higher than the outside temperature, so be careful not to get bored.”

“Warm and irritated?”Philin nodded.

"A new kind of heating is much better than a fireplace," Roland did not explain too much, but turned the subject to the other's purpose, "I heard you were here for witches?"

“Yes, Your Highness,” said Dawn, “I met a blue woman at the convenience market...” He told me the story of the day, “After returning to the family territory, my father told me the family’s history, so I thought she might be a witch.”

After listening to each other's stories, Roland was surprised that he did not expect that the Agra family would have ordinary people to survive, and has continued to this day."There is such a witch in the border town, and she is also called Aegsa."

Sir Sir Sir Walter stood up excitedly, "Can you please your Highness—"

“Let’s see one side of you?”Roland smiled and nodded, “Of course, she should be on her way back to the castle.”In addition, considering that she is a witch, I think it is better for you to take the stone of divine punishment, which is a basic courtesy for her."

"Ah, you are right."The jazz scrambled to take the stone from his underwear pocket and put it on the side of the long table.

"More than four hundred years ago, Takila had no such courtesy at all, and they were not hunted like animals by the church," murmured the nightingale in his ear, "for Agra, this thing is but a kind of research material for Agra."

“Then you can easily tell if what they say is true,” Roland said with a clamore.

Then he felt the nightingue gently choke his neck.

“The liar.”

...

“What do you want me to come back to?”Agsa pushed the door of the meeting room and said, "The battle of God's will is about to begin, I should seize every breath to produce weapons of confrontation ...", presumably saw an outsider, she swallowed the word devil, "if there is no important thing, the people tell me."

Probably because of her work with the alchemist, she also brought a hint of Kemo Stryor's style in her speech, and this spirit of dedicating every minute and every second to the production of the town made Roland, who was the owner of the town, slightly feel.He cleared his throat and said, “Cough, this matter is still very important.”Do you remember that four hundred years ago, when Takira was about to be destroyed, a team of servants separated from you and followed the great army to the south of the desperate mountains?”

"It seems a little impressive," said Egsa, unveiling her snow-flaked hood and lifting a blue show, "but what's the matter?"It's been so long."

When she showed her trueness, Philine and Sir Qi breathed a cold breath, and the latter knelt down directly to her, "You are indeed a Gasha!"

“Are you . . .?”Ai Gesha frowned.

“I’m a descendant of Karge, do you remember that name?”The jazzman looked up and asked expectantly.

“Of course I took the name,” she shrugged, “I have bought two mortal servants, one named Kav, the head of the family guard, and the other was the housekeeper.”She said, “So you’re the son of the housekeeper who sneaked away halfway with the magic stone and the test record?”

“What, slip... go?”The jazz rolled his eyes, “No, he—”

"Come on," said Egsa, "I don't want to see you again."
