Roland immediately picked up the phone connected to the third frontier city, "Let Selene not disassemble the festival cube first!

"Yes...... Yes, Your Majesty!" the messenger on the other side apparently hadn't figured out what was going on, but even so, he complied.

"Take me to the Frontier City," Roland said, turning to the Nightingale, "as fast as he can." ”

"Understood," the latter smiled and dodged over to grab his hand, "that might be a little dizzy." ”

Then the two of them instantly escaped into the fog.

Five minutes later.

"Uh......" Roland appeared in the underground hall with his mouth covered. I have to say that compared to when we first met, the nightingale's familiarity with abilities has made great progress. Shuttling through the black and white world is like surfing, one wave after another is overwhelming, but she can take advantage of the momentum to move forward, and her posture is smooth, and it is no problem to call it art. But these are not so pleasant in his eyes - especially the changing contours blur the boundary between plane and three-dimensional, and the feeling of sometimes turning the world upside down, sometimes upside down, is a hundred times more exciting than a roller coaster. "Finally...... It's here. ”

Nightingale smiled and patted him lightly on the back.

"What's wrong, Your Majesty?" Selene slowly descended from the roof of the cave with a large handful of tools, "I heard you were looking for me?"

Looking at the hammers, saws, and files rolled up on the other party's tentacles, Roland breathed a sigh of relief, "It seems that we have caught up." ”

But why is there a halberd and an axe in the tool? Could it be that she wants to chop the Rubik's cube into powder?

"Where are the ancient relics?"

"It's still in an underground lab. 」

He took a deep breath, "Can you copy it?"

Selene was visibly stunned, "Are you sure? 」

"Maybe it's not for nothing. Roland briefly described his thoughts, "The biggest disadvantage of steam power is that the fuel weight is too large, if there is a way to replace it with a Rubik's cube, it is likely to bring a new round of revolution to industrial production." ”

An efficient and powerful power source is always the core pursued by the industry, whether it is used in manufacturing, power generation, or equipment, it can cause qualitative changes.

Of course, it is not easy to take this step, the relationship between the traditional boiler and the Rubik's Cube is not a simple replacement, after the new heating method, the thermal cycle and interaction system, control system and maintenance will be changed, and he may face countless failures before success, but this may be worth his energy to try.

"Boil water...... I see," Selene thought for a moment, then was a little confused, "but...... I'm afraid it's hard for me to replicate without a careful exploration of the internals - after all, it involves magic, and you're not allowing me to disassemble it. 」

"Ahem, I mean, don't disassemble it like garbage. Roland coughed twice, "If it is for the purpose of imitation, it is carefully and carefully divided, then of course there is no problem." ”

"Is there still an inattentive and careless split?" Selene said in surprise, and then her tone seemed to be a little aggrieved, "In the past, in the Secret Society, anyone who damaged any relic thing had to be punished. And I have not been punished from the time I joined the union until the fall of Tachira. Nataya-sama also praised me personally, saying that I have a natural pair of skillful hands. If you are still reckless in doing research, it is estimated that there will be no core instruments left in the hall for a long time. 」

Faced with this boastful defense, Roland looked at the tools in her hand suspiciously, "You used them to disassemble relics before?"

"These?" Selene was stunned, "How is that possible. Didn't you give your sisters new weapons and equipment...... It turned out that those swords, guns and axes were no longer used. Instead of rusting in a warehouse, I can make something else out of it – I just happen to have a few bookshelves missing from my library. By the way, why would you use these discarded weapons as research tools?"

The nightingale immediately covered her mouth and turned her head away. Judging from her slightly trembling shoulders, it seemed that she had endured quite hard.

Roland couldn't help but feel a little embarrassed, "No, I thought you would fall into a frenzy as soon as you encountered something related to magic......"

"It must have been Pasha again," Selene held on to the large tumor with her mustache, "she couldn't tell the difference between fanaticism and interest...... What a true explorer needs most is sober and thoughtful thinking, as well as precise and controlled movements. It's not crazy to work all night for days, or to read words to a book or something—"

Seeing that the other party had a tendency to stop, Roland hurriedly interrupted her, "Don't talk about that, only if you figure out the structure of the festival Rubik's Cube, will you be sure that the imitation will be successful?"

When it came to getting down to business, Selene returned to normal, "It depends on the complexity of the Rubik's Cube. It's not 100% sure, but it's not unlikely. Because it has one of the most obvious features, which is that it can be manipulated without the need for magic, which means that the biggest difficulty is gone. 」

"The hardest way to replicate magic!" Roland instantly realized the key point.

"You're right. Selene nodded her beard, "Humans, demons, and underground civilizations...... Or other races, due to physical and mental differences, the way they use magic is very different. In the case of magic stones, I am afraid that we will never be able to embed the stone into our body like the devil, so as to obtain the possibility of multiple abilities. In the same way, if I hadn't transformed into the primordial carrier, the human body alone would never have been able to repair the core of the magic power. 」

"It doesn't require mana to wield, which means I don't have to research what kind of mana cyclones this long-vanished civilization has, and how to use them. To be honest, without enough data accumulation, this hurdle is almost impossible to cross. But now, as long as I do it exactly like the original, I can make the magic work the same way. Of course, this was still an extremely difficult thing to do in the days of Tachira, but now that there are mana cores that can be adjusted at will, things are much better. 」

Selene paused for a moment, "But there's another hurdle to solve. 」

"What is it?"

"Materials. "I've been studying the Rubik's Cube these days, and I've found that even though it looks like a stone, it's not made of stone. I can't tell what it was, maybe it's alien bones, or if it's solidarity, but I need more samples...... But as you said before, the Temple of the Damned has been emptied for years, and even this relic was only known by chance, so it is unknown if the same effect can be achieved with alternative materials. 」

"Materials...... Roland mused, "there may be another place where something similar can be found." ”

After counting the time, that remote place must have changed dramatically...... He looked up to the south, and if the frescoes in the temple weren't fiction, maybe he would find something there.
