Although the laboratory was designed by him, when he saw it with his own eyes, Roland still felt a sense of shock in his heart.

In the underground, where you should not be able to reach out your fingers, the glowing magic stones illuminate the road ahead, and the surrounding stone walls are covered by lead plates two meters square, and finally form a regular space the size of a basketball court.

The even, smooth lead baffles, with their staggered straight gaps, are lifeless with cold light falling on them. But it's just such a room, but it is pregnant with an invisible beauty.

This is the beauty of the industrial age.

"If we don't win the battle of the Divine Will, this place will be an ancient relic in hundreds of years, right?" Roland whispered.

And it is a relic with a very different style, which is different from the underground civilization and the devil.

The delicate abrasion marks on the lead plate are the marks carved by human beings.

"Perhaps. Pasha gently lowered the two of them, "But I've never believed so much as I do now—that humanity will make it to the end. 」

"That's what I thought, too. Roland smiled and walked into the lab.

The room is divided into two areas, the operation area and the observation area, which are separated by a concrete partition wall nearly half a meter thick, and similarly covered with lead panels. The glass in the center of the wall is specially made by Lucia, with lead oxide added to the conventional ingredients, and although the light transmission of the lead glass is far less bright than that of later generations, it can at least allow people to see the situation on the other side.

"Here you are, Your Majesty. A main beard came out from behind the door of the operation area, followed by Selene's massive body, which appeared with the air of a horror movie, but the bolts and rulers on her auxiliary hair quickly diminished the feeling, "I heard Pasha's notice when I was installing the last lead plate. Zoe, have they already brought back the Ancient Relic?"

"It's in this box. Roland placed the lead box on her main beard and walked into the operation area to examine it carefully.

"Well? It's exactly what you want it to be," Selene raised her tentacles, "but is it really necessary to do that? If the curse is just a light, normal walls are enough, right?"

"Just in case. If it is as I thought, the light it emits is not only invisible to the naked eye, but also extremely penetrating. Ordinary walls do act as a barrier, but they need to be at least a few meters thick. He turned back to look at the two ancient witches, "So don't act on instinct - even if the primordial carrier has a very high resistance, you must test it according to the rules before you thoroughly understand the nature of the Rubik's Cube." ”

Because ionizing radiation destroys the DNA structure of cells, leading to impaired replication, it is most damaging to tissues with fast metabolism. Organs such as the heart and brain, which do not replace once they mature, are much more resistant to ionizing radiation. Judging from the lifespan of the original carrier for hundreds of years, the aging cycle is surprisingly long, and theoretically it should also have a certain immunity to radiation. That's why Roland gave Céline the test.

Selene laughed, "You look a bit like the president of the Secret Society. Rest assured, strict rules have always been the norm pursued by the Secret Society, and I will not be careless. 」

Roland nodded, "Let's get started, then." ”

The isolation door was closed, and Selene was the only one left in the operation area.

According to the first article of the test regulations, the exits inside and outside the laboratory must be closed when studying the festival Rubik's Cube, and everyone except the operator can only wait in the observation area.

Through the lead glass, Roland saw Selene open the box and take out the Rubik's Cube inside.

As Sean had said, a faint blue light flowed through the cracks in the stones, pointing directly at the coins placed on the test bench.

"Interesting thing," Selene looked at it for a moment, "this thing isn't activated, is it?"

The wall blocked the transmission of sound, and Roland concentrated, also using his consciousness to reply, "According to Sean, it was still in close contact with the Earl of Grand Ducal Island after emitting a blue light, so I think it should be just a function like an indicator. 」

"Understood. Selene grabbed the Rubik's Cube, and countless tentacles poured towards it, instantly wrapping it into a ball.

"She's ...... What to do?" asked the nightingale.

"Perception. "The tentacles are far more sensitive than the human fingers, not only do they have all the touch, but they can smell and remember every bump and depression when they cross the surface. And a magical genius like Selene can still construct its outline and details directly in his mind - it's a pity that this part is described in a carrier thought, and normal people can't understand it even if they accept it. 」

"Can you see what she perceives?" Roland said with a slight surprise.

"If she's willing to share. Pasha held out a tentacle and nodded in front of the glass, "Now the Rubik's Cube is in front of my eyes. 」

It's a handy ability, almost like a mental network...... He used to think that he could only transmit consciousness, but he didn't expect that even three-dimensional scenes could be shared together.

"The length and width of the festival cube are basically the same, almost fifteen centimeters, and the interior is hollow, and you can feel the gaps, which does not look like a whole. Selene said suddenly.

"What do you mean?"

"It's kind of like a patchwork of stones. Wait a minute...... I seem to have found the mechanism. 」

As soon as the words fell, the entwined tentacles spread out one after another, and I saw a small opening behind the Rubik's Cube, as if the treasure that had been buried for many years had finally opened its entrance.

"Amazing," Roland couldn't help but sigh, "to figure it out so quickly." ”

It has been nearly a hundred years since the festival Rubik's Cube was left among the people, and those who have handled it for generations must have tossed it. But from the records, no one noticed that it was not actually a complete stone.

"I'll just say it's okay to leave it to her," Pasha laughed, "The magic cores of those underground civilizations were all patched together by Selene from the broken state. 」

"Your Majesty, I have an idea," Selene probed into her small mouth as she poked her tentacles, "and that's why it reacted to this coin alone. You said that the Rubik's Cube has been silent for many years, and at first I thought it was a problem of running out of mana, like a magic stone or a sigil. But once you get the real thing, you'll probably notice that there's still magic inside. So this thing is lacking...... Could it be what you call the element that makes the sun's ray?"

"Same as I thought. Roland curled the corners of his mouth, "You can try putting a coin in it - but this may activate the Rubik's Cube, so be prepared." 」

"Understood. Selene moved behind the baffle on the side of the test bench, an arc-shaped block of lead with four small holes in the center for the auxiliary to pass through, like a large shield with observation holes. When she threw the uranium coin inside the Rubik's Cube, the small opening closed instantly, and the light on the top turned crimson.

You guessed it!

Roland and Nightingale looked at each other and suddenly became a little excited.

Selene continued to fumble for a while, and suddenly, a red light shot out from one end of the Rubik's Cube and landed straight on the wall, adding a new touch of color to the cold laboratory.
