"So this is the 'Rebecca Crystal' that you successfully made... well, yes, it looks the same thing."

Sitting in his big account, looking at a large basket of things that Rebeccain took, Gao Wen nodded slightly.

It is a basket of gray-black, ugly, strange materials, some loose like sand, some are tied together, but no matter what form, the inside is almost evenly embedded with countless fine particles, and compared with Rebecca For the first time, the "waste" made by the sloppy paste, the crystal grain content of this basket of finished products is significantly higher, and the average diameter of the particles seems to be much larger.

This shows that Rebecca not only found the formula, but also vaguely touched the number of ways to improve production.

When he heard Gao Wen, Rabe was very embarrassed, and Rebecca was embarrassed. Miss Viscount scratched his face, which was black and smoked, and smiled like a 17-year-old. A silly scorpion that burned explosives in a cement kiln: "Hey... ancestors, do you really think this thing can be called this name? Not all very powerful people can name something else with their own name... ”

"These crystals were invented by you. Are you not powerful enough?" Gao Wen glanced at the unconfident n+1 layer granddaughter. "Well, although there is still a lot of room for improvement, it is indeed already Repeatedly realized the 'product', the name Rebecca crystal is deserved."

Rebecca entered the state of silly music: "Hey, hehe..."

"Don't be stupid, talk about how this thing was made in the end," Gao Wen glanced at the iron-headed baby with a smile. "Although any new material appears to have luck, I still want to know." How can such good luck come to us?"

"Oh, it’s really true, it’s a coincidence," Rebecca scratched his face. "It’s actually burned according to the original recipe you gave me, but it failed yesterday when I tried to restore the firing process. Several times, no matter which ratio was used, I doubted it on the stove, so I checked the condition of several kiln and found that one of the kiln's inner wall fell off a large piece..."

“Is it a big chunk?” Gao Wen frowned, realizing that the key to the formation of these “Rebecca crystals” was probably on the pieces of the kiln wall that fell off. “So the materials for building the kiln are also involved. The reaction?"

“This is one of the reasons, because those kiln also use rune heating, so they were mixed with quartz sand when they were built, and in addition to quartz sand, another important reason is the stone from the dark mountains. ”

"The stone of the dark mountains?" Gao Wen repeated it.

"Yes, I compared several sets of records and found that there is two differences between the furnace and the other furnaces. The first is that the quartz sand used to build the kiln is mixed with the raw materials, and the second is the material used in the raw materials. Limestone was dug from the dark mountains. The limestone from the other furnaces came from the Baishui River and was transported from the west side of the logging yard. If they were used as raw materials, they would not be used even if they were mixed with quartz sand..."

Two conditions, quartz sand and limestone from the dark mountains...

Gao Wen is slightly stunned. These two conditions are the exact conclusions that Rebecca has made after multiple comparisons. Without doubting its authenticity, what role do these two things play in this process?

Quartz sand is also imaginable, because it is a weak guide material. Although it is extremely cheap, it is also a real magic material, and it is one of the raw materials for making artificial crystals. But what about limestone from the dark mountains?

Why can't limestone mined from other places?

He threw out these questions and asked Rebecca a glimpse.

Miss Viscount did not think about these details, she scratched the back of her head: "I am happy, I have not thought about it..."

“The dark mountains were once shrouded in magical waves. There are still traces of erosion by elemental tides in many places in the mountains,” Gao Wen said thoughtfully as he touched his chin. “Perhaps this process has changed the nature of some of these minerals... ...to make them have the characteristics to participate in the magic reaction?"

In the absence of more experimental data and theoretical guidance, Gao Wen can only make such a bold guess, but no matter what the real reason is, now Gao Wen has identified one thing: "Rebecca Crystal" in this The world is absolutely unique, at least in the Kingdom of Ansu.

Who would normally go to the dark mountains to dig the mountains and burn stones?

“After confirming that the key lies in quartz sand and dark mountain limestone, I tried several ways to improve the crystal proportion and quality,” Rebecca added. “I found that increasing the proportion of quartz sand can make the crystal yield higher, but A lot of crystals will be broken off when they are baked. Increasing the proportion of limestone will increase the ability of the finished product to store magic, but after a certain percentage, it will not form a crystal. And I also found that the temperature and firing time have a great influence... There are too many items to test, and I can't finish it all at once, just burn it out according to the best method I use now. Hey, that's what you are in front of you."

Gao Wen asked directly: "Can ordinary people complete this process?"

"Yes, but most people don't understand what 'cross-control' and 'observation group' you taught me, so they can only do it according to the method taught them," Rebecca replied. And they are very careless, even if they tell them how to do it, they often make mistakes in the ratio, or the time control required to burn the crystal in the wrong time is much stricter than burning bricks."

It is imperative to improve the average quality of laborers.

However, even a few qualified cultural teachers in the territory can't find out... All the people who know the word count are already overloaded. Where can I find someone to set up an education team?

Going to Tanzan town to hire? There are not a few words in the town of Tanzan! The person who can read and write is not a businessman's child or a "decent person" who has entered the aristocratic residence and served as a housekeeper and a clerk. How can these people be willing to come to such a place where the birds are not squatting, followed by the pioneers, and they are not themselves poor? Serfs and the poor...

Gao Wen touched his head. Whenever a new problem appeared, he always subconsciously had this action, as if he was confirming his hairline...

"Ancestral adults?" Rebecca cautiously opened.

"No, it's okay, this is a long-term problem," Gao Wen waved. "You will continue to produce according to this 'optimal plan'. When you have leisure, try a better match. In short, these crystals The more particles, the better, even as important as the output of steel. Right, you have to find a way to extract the mixed crystals, and the dark residue next to them is useless. You can try to mash them. Filtered with water, the crystal is harder than the residue, and it is heavier. After mashing, the water wash should be easy to separate."

Rebecca nodded as she listened. After Gao Wen finished speaking, she smiled and scraped it together. He whispered like a sly kitten. "That... ancestor, I heard Aunt Herti say, you are I am going to make this crystal a magical prop that will explode?"

"It's almost a meaning," Gao Wen glanced at the girl who always had a whimsy. "What do you think?"

"You are going to use the detonating array in the crystal system of the 铎 铎 crystal on this crystal," Rebecca's eyes sparkled. "But how do you want to detonate?"

Gao Wen frowned, this is exactly what he is thinking about.

The detonation arrays in the ancient crystals are the same as the common small arrays. They are magical arrays that cannot be self-charged. In other words, they need an external magic source as the “enable energy source” for subsequent detonation. In the crystal, this part of the energy is provided by the crystal itself, but in his "Art No. 1", there is no such energy.

The magic stored in Rebecca crystals can't be extracted to participate in other magical reactions except for being directly bombed as explosives. Therefore, the detonation array attached to Rebecca crystal must use other magic to act as " Start-up power, then where does this part of the magic come from?

Use another piece of energy storage crystal as a "burst battery"? Then this loses the meaning of "cheap".

Use the magic of the magician to activate the array? Then this loses the design goal of "Let ordinary people use it."

"Let's just say it. Look at your eyes and you will know that you have an idea." Gao Wen glanced at Rebecca. The girl in front of her is really not a person who can hide things. Even if she doesn't ask, she is afraid that she will not. Live to say your thoughts.

"This is the case," Rebecca did not sell again. "I studied the detonation array and found that the startup magic it needed was actually quite small..."

Gao Wen nodded: "This is of course, after all, it is to use the array of self-explosion when the crystal is about to expire. Its starting energy demand is definitely optimized and it is not known how many times."

"Then I found one thing," Rebecca added. "The 'runch trigger' I invented, it will produce an extra magical impact when it is closed. It is very weak, but it does exist... ”

"Wait!" Gao Wen interrupted Rebecca's words instantly. He vaguely realized that he had caught a key problem that had been ignored for a long time. "You said that the rune trigger structure will produce magic at the moment of closure? You are sure Isn't that the magic of the magic net buried in the ground?"

"I have confirmed it several times, because I have a strong sense of magic in my childhood, so 'seeing' is very real," Rebecca stressed with a hard end. "The rune trigger has an extra when it is closed." Magic, and I also found that it is not just a rune trigger. As long as the original complete rune group is taken apart and then closed again, there will be an 'instant magic'. This moment the magic comes quickly. Fast, it’s a blink of an eye, but if you want to detonate something, it’s enough to have such a blink of an eye.”

Gao Wen immediately fell into meditation, and almost woke up when Rebecca was nervous: "Ah... very good, very good, then you follow your own ideas, put your rune trigger and that Try to make a combination of the detonation array. Let Herti help, I said that I told you."

Rebecca smiled and smiled, but before she was ready to leave, she suddenly remembered something: "Oh, ancestors, do you think the name of this popping prop should be in the future?"

Gao Wen thought for a moment, and Bao Xiang solemnly replied: "Art."

Rebecca: "Hey? Is this related to art?"

Gao Wen’s face is serious: “It’s called art.”

Rebecca turned his eyes and thought about it. He felt that his ancestors might have other deep meanings, so he nodded happily: "Well! Art!"

Rebecca left with a sigh of relief, but Gao Wen was sitting in the camp for a long time and could not calm down.

He was playing with a pen in his hand, unconsciously turning around, and when he reacted, he realized that he had written a line of text on the draft paper:

Magic, what is magic?

(Ah, I actually updated a chapter?)
