Marie Curie looked at the white cat, which glowed with a pale blue light throughout.

That light was not the light of the chain reaction that Marie Curie had become accustomed to, it was some kind of light that was closer to the essence of the world.

The cat tickled with ease, and didn't seem to take humans including Marie Curie seriously at all.

Marie Curie stared at the cat, not paying attention to the expressions of the people around her, so she didn't know that the people around her could not see the cat.

Marie Curie, of course, remembers that her friends also had white cats. But time was too long, and she wasn't sure if the cat in front of her was the one or not.

She wasn't even sure if the cat was her hallucination.

At that moment, the cat finished tickling, and then it looked directly at Marie Curie's right hand.

Marie Curie remembered that she was still holding the pocket watch in her right hand, which was the object left by her friend, the testimony of a long memory from many years ago, and the ticket of longing.

It was just an ordinary pocket watch, but Marie Curie had radiographed the inside, and she knew that it had a very complex and incomprehensible internal structure, as well as four Class-A concept cores.

- This pocket watch must have a special purpose, but I can't use it - no one in the world can use it.

Marie Curie has been convinced of this for many years.

Although it is a carrier of precious memories, Marie Curie believes that it should be given to those who can use it.

Despite this, she still clutched her pocket watch tightly, without the slightest intention of letting go.

Sure enough, for a centenarian, memory is her most precious treasure.

The cat barked, and even Marie Curie, who didn't usually have a cat, could hear it urging.

Marie Curie crouched down and stretched out her right hand to the cat, spreading her fingers so that the watch was fully exposed to the soft blue light emitted by the cat.

Then, a miracle happened, the pocket watch, which had long been suspended, suddenly moved the second hand.

Immediately afterward, Marie Curie heard the sound of the mechanism in operation of the case, and the pocket watch, which had been dormant for many years, gradually came back to life, and the hour, minute, and second, which had always pointed to the last time it left its original owner, began to move forward again.

- You can't be wrong, it's their school.

- Although I don't know who managed to cross the line and become a champion in the end, this is definitely their school!

Marie Curie held back her tears and handed the watch to the cat.

The cat unceremoniously picked up the watch, turned around and left.

In the blink of an eye, it completely disappeared from Marie Curie's vision.

- It's just here to get the watch.

- Isn't there any sense of catching up with old friends at all?

- Or are you ...... Do you have more pressing things to do?

- Definitely.

The greatest dream of those people was to open the door of truth that we had all seen, and to see what was behind the door with the Kabbalah Tree inscribed with the pattern.

- Are you already, ready to kick the door?

Marie Curie's old heart beat violently, as if she had returned to the twenty-year-old afternoon when everything was young, and the afternoon sun of Copenhagen was shining gently on her.

"Nils, the principles of the world don't roll dice!"

"Don't dictate the principles of the world, Albert!"

The tea party was never peaceful, and the young talents were always in a never-ending quarrel.

"Your paper doesn't even have falsifiability!"

"I refuse to answer your question! Because it's a declarative sentence! ”

Sometimes, of course, young talents are excited about new assumptions and ideas.

"Listen to me, I have an idea. Suppose there is such a cat, he is kept in a black box, and no one can confirm its status except to open the box, and then there is a device in the box that contains a radioactive ...... with a very short half-life"

Marie Curie remembers mentioning this hypothesis when she had just discovered the half-life of radium, and that it was the first time her discovery had been used by young talents in their ideas.

The joy of that time once again flowed through the heart of Marie Curie, who was already old, as if everything happened yesterday.

Everything was so clear, so clear that it didn't look like a hundred years of memories had passed.

Marie Curie clearly remembers that in the courtyard where they drank their tea, there was a sculpture of a door with a picture of the Kabbalah tree that had been handed down from time immemorial.

The sculpture had been made by Nils with a stonemason, who he said was called the Gate of Truth, the symbol of the secret organization that met in this courtyard.

The door of truth, always in Marie Curie's dreams, has never been absent for so many years.

- You're ready to kick the door, right?

**

Eve Curie quietly equipped a small telescope so she could see what her mother was holding in her hand.

She remembered the watch, which had a door carved into its lid and a Kabbalah tree painted on it.

Mom said it was called the Door of Truth.

The door that Eve Curie had just seen in his hallucination was modeled after the engraving on the watch.

Eve Curie didn't know why her mother was crouching down and why she took out the watch.

But she noticed that the watch had suddenly started moving.

- This ...... Surely what an important tip!

- This new school of thought has something to do with mom?

The next moment, Eve Curie saw the watch float, and before she could see it clearly, it disappeared all at once!

- What?

Eve's eyes widened, and she nearly let the small one-sided telescope caught in her eye socket fall.

She looked to the side, and sure enough, she noticed that people from other schools were already using various means to detect invisibility.

She looked at Burberdin, who was closest to the podium, and saw that the old man was also looking at her.

Apparently the old man was trying to get some hints from her.

However, Eve Curie knew nothing.

The watch never left the chest of drawers in her mother's laboratory, which had high levels of radiation when her mother was not in it, and even if Eve Curie was a professor of the school, she had to wear physical protective clothing in that radiation.

Even in the Marie Curie school, you have to go to the level of a mentor to suppress and remove radiation from objects as casually as your mother did.

Eve is still far from being promoted.

Neil Hold looked through the gadget and asked, "You see?" ”

"Of course."

"Marie Curie, who has no quarrel with the world, is she finally going to go out of the mountain?"

"I don't know, in my opinion, it's more like she gave what she was responsible for keeping to the person she had been waiting for."

"Are you saying that the new school is better at fighting than Marie Curie's?"

"You're wrong, the Marie Curie school is not good at fighting, they are just, simply destructive, and when they really fight, there are still a lot of ways to target. Very much. The guy on the other side of the gadget continued, "This new school of thought feels a little difficult to get along. Are you sure it's useless to detect invisibility? ”

"At least the methods I have to detect stealth are useless."

"Okay, let's try divination, the key word is...... Cat. ”

"Yes. On the Dahua Empire's side, it used cats as keywords to divinate things. ”

"This is super top secret, isn't it?"

"Of course. But who do you think I am? The guy on the other side of the gadget said lightly.
