The Third Frontier City, an underground laboratory.

After reading the report, Roland and Anna rushed here as soon as possible, and through the thick protective glass, he saw that in the center of the laboratory covered by lead plates, two ritual cubes were activated—one of them seemed to be normal, while the red light from the other was significantly shorter.

"That Rubik's Cube with a short red light...... Is it the latest imitation?" asked Anna keenly.

"That's right, in fact it came about because of a mistake. Selene replied with great interest, "Usually, the internal lines of the Rubik's Cube are carved by thin wrists, and if the material is damaged, it is easy to be carved. Normally, these faulty 'stones' would have been discarded, but when Slender Wrist carved Module 236 a week ago, it wasn't until the finishing touches that a tiny crack opened in the center of the stone, causing the component to be flawed. 」

The materials used in the festival Rubik's Cube are all from the extreme south, and according to the murals, these relics have been sleeping underground for at least a thousand years, and it is normal for the wind and water to soak for so long and the texture is not good. Roland said thoughtfully, "And you didn't throw the number 236 away?"

Selene nodded, "I thought it was a pity at the time, after all, it was finished in its entirety, and maybe it could still come in handy. So I replaced the same part of the early Rubik's Cube with this No. 236 to see if it would work. 」

Hey, this is a nuclear torture instrument, Roland secretly wiped his sweat.

"Please rest assured Your Majesty," Selene said as if sensing his thoughts, holding up her sarcoma-like head, "I was testing at a weapon testing ground in the mountains of a desperate situation, and if an accident happens, it will never affect Neverwinter - this is the basic belief of the members of the Quest Society, even if I die unfortunately, you don't have to be sad, I have already put my personal safety ......at risk in order to seek the truth."

Looking at the other party's gushing appearance, Roland's original worry quickly dissipated, "Get down to business!"

"Ahem...... It's rude," Selene cleared her throat, "Anyway, as you can see, the Rubik's Cube is still activated normally, but the range of the red light has been reduced to less than a tenth of what it used to be. However, this did not prevent the power of the three-cylinder Rubik's Cube from being heated, so I did another heating test to see if there was any change in the heating efficiency of the shortened red light - this test continued intermittently for two or three days, until I checked the uranium sheet, and I was surprised to find that it had not changed at all, and even the consumption of mana had been reduced a lot. 」

Anna pondered for a moment, "Is it possible...... Most of the Rubik's Cube is spent on maintaining the red light?"

"A high-level awakened person younger than Agatha," Selene approving, "I've been thinking about it for a long time and leaning towards this answer - if that light is made up of countless tiny balls, it's not easy to get them to go in the same direction. And the test has proved that as long as the red light is not touched, the front and sides of it will not be affected, so it seems that the shortening of the light does seem to save a lot of effort for the Rubik's Cube. 」

"Wait," Roland said suddenly, "that means that the flawed 236 component determines the radiation distance of the Rubik's Cube?"

This is a groundbreaking discovery, even more significant than solving the durability problem! There are more than 300 components of the festival Rubik's cube, and these stones of different shapes and textures are put together like building blocks, and no one knows how the magic works inside. But now, there seems to be a way to resolve the problem.

"Think so. There was also a hint of excitement in Selene's tone, "Maybe the lines on each component play a specific role, and if you can analyze the meaning of those carvings, you may be able to understand how the festival cube uses magic." 」

"One component is responsible for one function, and in that respect, the radioactive mindset is quite similar to ours," Anna laughed, "Should I say it's human luck?"

"Of course. Roland nodded without hesitation - he naturally understood the meaning of Anna's words, the difference between different civilizations is huge, not only in form and language, but also in terms of thought, the probability of finding an object that can be understood and understood is very small. The Underground Civilization is an example, it is also the core instrument for controlling magic, but it can only be controlled after becoming a carrier, and Selene has studied it for hundreds of years, but still has not been able to understand its principle, which shows the difficulty of this.

In a sense, civilization is lonely.

Although he had comforted everyone by saying that even if he didn't need to rely on the inheritance of the gods' relics, he could still learn the knowledge of those fallen civilizations, but in fact this was not an easy thing to achieve, especially when there was no one to guide and only grope on his own - when the way of thinking is completely different, how can he learn from the results of the other party?

If Selene's speculation is correct, then a civilization that can resonate with humanity may lead to new ideas for the study of magic.

"By the way," Anna suddenly smiled playfully at Roland, "Now that the power of the Rubik's Cube has been finalized and there has been a breakthrough in durability, shouldn't the reward you promised be honored?"

Looking at the blue eyes that shimmered with the clear light of the lake, Roland found that he couldn't say a word of refusal at all.

"Yes, yes...... My Highness," he couldn't help laughing, "I'll show you when I get back." ”

......

"Tutu Tu Tu ...... Boom ......"

The faint noise outside the window caused Zoroya to lift the quilt in a daze and sit up.

"Hah-" She yawned sleepily and reached for her clothes with both hands at the end of the bed. It was a sound all too familiar to her, the roar of a steam engine at start. When it rings, it also means that a new day has begun, and the busy and orderly work is about to begin.

But it was really early, she glanced at the still sleeping echo on the other side of the bed, and lightly put on her coat. It's even more diligent than himself, and it's in the castle—

Wait a minute, Zoroya was suddenly stunned, this is not a factory area, why is there the sound of a steam engine? If you think about it carefully, today should be a rest day, most witches will sleep until noon, and before the time for dinner, the castle is often quiet, as if it is empty. Could it be that I was dreaming just now, and I happened to dream about the scene of work?

"Boom, boom...... Pop ......" but the sound of a steam engine was heard outside the window again, accompanied by bursts of laughter.

"This thing is so interesting!"

"Your Majesty, let me try it too!"

"And me, and me!"

"Uh...... What's going on?" Echo rubbed his eyes and sat up.

"I don't know, maybe that guy Mitsuki is making trouble again......" Soroya stretched and walked to the window to open the thick curtains, and the sunlight poured into the room in an instant, illuminating the entire bedroom. Obviously, the sun has climbed into the sky at this moment, and it is not too early.

When her eyes adjusted to the light, she looked downstairs and was stunned.

I saw that the gate of the castle was full of sisters of the Witches' Alliance, and everyone's eyes were fixed on the center of the courtyard, and their faces were full of eagerness.

Following their gaze, Zoroya saw that Her Highness Anna was sitting on a strange four-wheeled cart, which was still running merrily around the courtyard even without a horse, and Anna's smile on the cart was so bright that it even overshadowed the warm morning light.

This scene instantly attracted all her attention.
