"Her Highness Tilly, she...... Ability isn't flying, is it?" muttered Nightingale.

"Well, although the flying magic stone can also make her fly, but she can't carry such a large weight," Roland replied as he looked at the unicorn hovering overhead, "What's wrong?"

"I've heard you say many times that you've been watching you when you're drawing and testing the internal combustion engine, but it's still incredible to see it in person...... Man can really fly like a bird with the power of external objects. "It's just a combination of metal and wood." ”

"It's just metal and wood, really, but it's us who bring it together," Roland said with a slight smile, "hands, magic, and cognition...... Therefore, it cannot really be called the force of external things. ”

"Everybody—can they fly like her?" said Nightingale softly, "including me—"

"Well, everyone. And that includes you. Roland affirmed. The sky was no stranger to Nightingale, she had flown in a hot air balloon and she had flown on Maisie, but those were obviously nothing until she flew freely and freely. Even the nightingale with magical powers, let alone ordinary people without special abilities, the charm of flying in the sky, since the moment people look up at the sky, they have been deeply immersed in it, unable to extricate themselves.

The pioneer of the Society of Strange Things is the best example of this.

Thirty minutes later, the Unicorn landed steadily on the runway.

"How does it feel?" Roland asked Tilly as she ran over with an excited look on her face.

"This plane is amazing!" she said, her eyes lit up, "and in terms of feel, it's many times more agile than the Seagull." Seriously...... Although Wendy's ability to control the wind is not bad, it is always difficult to fully match my intentions, and this one is different. The speed, pitch, and deflection during the flight are under my control, and it can be called a movement from the heart, like a sibling!"

Belch...... Roland couldn't help but feel ashamed, and despite the fact that the Unicorn was based on a number of well-established biplane designs, it was essentially a prototype with a rudimentary technical component. The control of the rudder surface is all by hand, and the altitude and speed are all by feeling, and it is a huge step forward to be able to fly smoothly. If he didn't know the plane well, just listening to Tilly's description, he would have thought that the other party was flying a modern fighter plane with more than four degrees of telex and flight control computer assistance.

Probably this is the big guy.

"So...... Satisfied?" He beckoned to the hangar supervisor, "That's all for today—"

"What are you talking about, brother," Tilly interrupted, "how can you be satisfied in thirty minutes?"

"Then you fall down ......"

"To tell you. You still have a lot of work to do, don't you?" she waved her hand, "Go ahead, you don't have to guard me here, I still have a lot of flying methods that I want to try." ”

Looking at the back of the other party rushing away, Roland shook his head helplessly.

The plane didn't break down at the start, it was considered to be at the level expected, and at Tilly's level, she should be able to familiarize herself with the unicorn's new characteristics in no time. Coupled with the fact that she can get out of the plane on her own at any time, there is really no need for her to keep an eye on it.

"Looks like you're disgusted. Nightingale said with a heart of schadenfreude.

"As long as you talk a lot," Roland gave her a blank look, "let's go." ”

The nightingale grinned and grabbed him and escaped into the fog.

......

As soon as he returned to the castle hall, the guards greeted him, "Your Majesty, the third frontier city has sent a message that the task you assigned has basically come to fruition. ”

"Oh?" Roland said, raising an eyebrow, "Where's the report?"

"They said they wanted you to go for yourself. ”

It seems that what the two of them found in Daqing Port is not something that can be explained in a few simple words, he thought for a moment and said, "I know, let's go now." ”

After entering the underground, Selene was already waiting for him in the main hall.

"Your Majesty, you are right in your guess, the Endless Cape does have the materials to make the Rubik's Cube. She stretched out her beard and showed the two samples to Roland, "The gray-yellow stone on the left is very similar to the Ritual Rubik's Cube for magic, if not identical. If there are enough of them, I can start copying. 」

"Plenty of them...... How much?"

"Let's try a few thousand dollars first. 」

Belch...... You're welcome, even if the sample sent is not large, a few thousand pieces can fill the floor of a room. In this way, he thought to himself, the excavation of the "Cape Ruins" was imperative, and the sooner the better. "I'll have someone collect it. And what about the other one?"

"The other can be described as incredible. First of all, it's safe to say that the light it emits doesn't do any harm to the test animals, and it seems to be just a normal light and not the kind of ...... you're worried about."

"Radioactive particles. ”

"Exactly. Of course, it is not ruled out that it is too weak to be detected by animals – but in that case, it is not a cause for concern. Selene picked out a slice of "stone tablet" from the bottle on her right and placed it in Roland's hand, "I commissioned Miss Lucia to break down a small piece of it, and found that its composition was not much different from sand. 」

"Follow...... ...... sand?" Roland said in surprise.

"It's hard to imagine, right? it just looks like a stone—or a little bit of gravel, but it's flexible and glows when compressed, and there's probably nothing weirder in the world. 」

"Well......" he said, playing with the sample in his hand, pondering for a long time before speaking, "I can't say that. ”

"Do you know what this thing is?"

"Not really, but I thought of something else...... "Since matter is a combination of elements, in addition to the elements themselves, structure is also a major factor affecting their properties. We find it strange because we know too little. ”

For example, carbon is called diamond in a tetrahedral structure, and graphite has a hexagonal layered structure, which is so brittle that it can be broken by hand. If you tear off one layer, it is graphene, which has excellent electrical conductivity, but when two layers of graphene are stacked on top of each other and rotated at a slight angle to each other, it will undergo a completely different change - it will become an insulator. And when it is lowered to a certain temperature and injected with electrons, it is transformed into a superconductor in turn.

From beginning to end, there is only one element in the performance, carbon.

This is the mystery of the material.

In fact, even in later generations, the exploration of the microcosm has only opened up a tiny tip, and in this dark realm without theoretical guidance, people do the same thing as they did thousands of years ago—permutations, combinations, random groping, and even the most common elements can be shocking when mixed together.

Whether it's the "Luminous Stone" or Sylvie's various coatings, it may not be mysterious because of magic.

It's because people know so little about it.
