After winter, the snow stopped a lot.

Roland groaned a little song and looked at the three manuscripts on the table.

They are a new ammunition trial and production plan, a new generation of light weapons design schemes and a Master ' s tower construction project.

The first two are the products he has been thinking about for a long time, and now with the frozen temperature control of Agusa, the nitric acid production in the town has increased greatly, and the stability of the large-scale production of nitroglycerin has also been solved, and the conditions of double-based hair* injection have basically been met.

Although it is known that this kind of emitting* drug is to dissolve nitro-skini oil into nitroic acid* glycerin, and finally get viscous adhesives that can be sliced or granulate, the specific ratio also needs to be slowly tested by the alchemist.

Fortunately, Kemo Squeer is now very skilled in quantitative and qualitative tests, and if this task is entrusted to him, it should be possible to get results in a week or two.

Since the production of new drugs, the development of new light weapons must naturally be on the agenda.

Compared with the large-caliber wheel selected at the time, the dual-based launch* drug can achieve the equivalent lethality with a small amount of weight, so from the perspective of comprehensive power and cost performance, the new small-caliber automatic weapon is an inevitable choice.

Of course, its specific parameters need to be further determined according to Anna's results.

Roland took a sip of hot tea and placed the third manuscript in front of him, which was also the thing of most interest to him at present.

/ mqul.

Compared with previous plans, the contents of this document seemed very incongruous at the request of Ai Gesha, who intended to build a mage tower on the other side of the Witch's Building for printing research and printing.

Think about it, a forest of chimneys and factories, mixed with a towering magic tower, this feeling is simply... very fashionable.

Roland couldn’t stop laughing.

On the side of the fish-cooked nightingale tossed a white eye, "Is it so interesting to print?"The kingdom of witches has many seals, but in the end it is still lost to the devil.”

"But there are some very interesting things in it," said the prince, drawing out of the drawer a thick book, which was translated from the test notes left by the exploration meeting, and recorded all the recipes obtained by the secret Society for more than two hundred years.

For him, it’s a completely new continent.

After Agratha had finished translating, Roland spent almost the whole night on the book, looking at the dazzling list of magic stone uses and combinations, which was almost like the assembly of runes.Probably when the chief alchemist got the "primary chemistry", he also held such excitement and excitement to read those chemical formulas.

For knowledge that has never been seen, even if it is only fur, it will also seem very attractive.

“For example?”The nightinge came over.

“Like this,” Roland points to a line on the page, “the ancient witch called it a listening lettering, which can be used for long-distance communication, similar to a tracking print, and once made, it can have an effect separately.”He moved his finger down, "The material is also very simple, only need an echo stone and a marker stone."

According to the book, this printing effect is tens of miles long, although it is not as good as the mobile phones supported by future towers and satellites, but it is also enough to be used as short-distance walkie-talkies.

“Yes?”The Nightingale probe glanced at both eyes, reached out and opened his finger, pointing to the right page, "But here it is written that the echo stone comes from the fear of the devil, and the marker stone is common in the devil's camp, how can you get these two kinds of magic stones?"

"No, we already have the material," Roland said with great interest, "the red crystal that the lightning finds in the remains of the stone tower is an echo stone, and as for the marker stone, it is also a trace print of the composition of the piece, such as the trace print, and the lettering Tilly carries several groups, as long as it is to open one."

"Even if Ai Gesha can do it, you can only get a listening print at best."

"Let her try her hand, anyway, after dealing with the devil, the magic stone will be more and more."There was no conditions to study the magic application before, and now with the technical support of Agra, he will certainly not let go of this almost empty resource.

"Well," shrugged the Nightingale, "what kind of magic stone does it need?"

“This... I remember on the last page,” Roland turned to the end of the book, “yes, what’s your combat effectiveness test results?”

The Nightinge suddenly staggered, and after a moment, he spat out two words, "Secret!"

It was hit by Anna.

"I found it, here," he said, "all the four magic stones needed are written unknown... presumably for secrecy, not recorded in written form.But according to Agra, most of these magic stones come from high-level demons, and even if they are written, I am afraid few people will be able to get them."

"Then you hang such precious things in the hall," cried the Nightingale, "if you knew it above, I'd be angry with you."

Because it is not a precious thing at all, probably ... it is equivalent to more than ten kilograms, Roland smiled and did not answer.

...

This time he waited until Ai Gesha had finished a day of acid work before calling her to the office.

"This is the Master's Tower I designed for you, can you see," Roland erected the drawing, "the basement is the warehouse, there are three floors above, namely, the apprentice test room, the main test room and the office."

“Why is it called the Tower?”Agra has frowned, “I just want a chemistry lab like Mr. Kemo’s, a little more spacious and transparent.”And such a stone tower is very troublesome to build, Takila because of the small size of the city has to make a tower, you have a lot of open space here ah."

That's not fashionable!Roland shouted in his heart."In short, the construction problem is not difficult to solve, in addition to the above functional range, do you have any other requirements?"

"No," she said, "if you insist."

"Very well," Roland put down the sketch, and then recounted the morning's thoughts, "can you do the print alone?"

"No," said Egessa, shaking her head, "the seal is a magic stone connection, but the material that conducts magic is very complex, and most importantly, it needs to use the blood of the devil."

The prince couldn’t help but say, “What?”

"You are not mistaken, it must be the blood of a living devil," she said, "and the secret will be tested tens of thousands of times in groping for the nature of magic, and finally prove that the flesh and blood of witches, devils, and evil beasts are very different, and they can play a very different role."

“The witch’s flesh?”Roland was surprised, he suddenly realized the meaning behind these words, can not help but ask, "What role can they play?" 」

“The punishment of the army.”Age said without expression.
