The walls here are black, the floor tiles here are black, the ceilings here are black, and the twelve doors here are also black.

They are inlaid equidistantly around the round room on the curved brick wall.

In fact, there are some metal lamp stands on the wall with three candles on each.It's just that the original blue candlelight has been extinguished, making this deep underground room not occupied by gray mist as dark as a night in the mist...No, maybe even darker than that, Because everything here is black.

With a wave of Maca's hand, he pushed aside the magic elevator fence door that could no longer be opened automatically, and walked in with a soft light in his other hand.

"Speaking of it, I actually always wanted to come here to walk through every room, because there are many hidden magical mysteries that may not be useful, but most of them are complicated and interesting."

Maca led Sarah who was following him, walking inside, and said to herself:

"Look! Behind that door is the planetary room, which should have been constructed by magic by some wizards who like to study astronomy in ancient times. Entering into it is like entering the starry sky of the universe. It's just that some planets are caused by magic for too long Not very stable, like Pluto, which often explodes..."

"I think the room next door can be called the'brain hall'. I guess it should have something to do with your alchemists-there is a huge glass water tank inside, which seems to be a brain activated by alchemy. , I guess that may be another way of pursuing'immortality' considered by ancient alchemists..."

"The next room..." Maca said, moving his arm to the left and pointing to the third door, "Oh, it's the time hall. I've been there a few times... I feel a bit like me. My subtle fate."

He didn't seem to want to introduce Sarah to the situation in the time hall very much, and just passed it in one sentence.Soon, his finger pointed to the fourth black door.

"That's right, this one is correct." Maca nodded. "Professor Dumbledore said that there is a power that is'more miraculous and more terrifying than death, wisdom, and nature.' , At the same time... is also a very important power that is missing in your soul."

"Is it the'love' you mentioned before?" Sarah said immediately.

"It's just that Professor Dumbledore calls it that," Maca spread his hands. "Actually, I don't really understand what its essence is... I just think it can be'love', but it can also be It's'sin'."

The voice fell slightly, and when Sarah couldn't help but fell into thinking when she heard it, Maca walked straight towards the door step by step.

"I wanted to pay attention to them before, but it was not very convenient because it was the Ministry of Magic; but later, I no longer have that free time... Including today, I can only take a look at this one, the others It depends on whether there is that opportunity in the future."

After that, he stretched out his hand and gently stroked the black door.

"By the way, it's locked... In Dumbledore's words,'always locked'."

"No one has opened it?"

After Sarah heard the words, she finally stopped thinking that seemed to be meaningless to her right now, and then approached the door of the room.

"To be precise, it is'no one can open it'." Maca said, "Most of the buried building of the Ministry of Magic has been repaired and reconstructed, but the Department of Mystery Affairs has always maintained the Wizarding Council. The appearance of the period. Nothing else, just because it cannot be changed by modern wizards alone-including this'locked' door."

While speaking, his palm was still lightly against the door panel, carefully exploring the secret that the door could not be opened.

"Oh, I suddenly remembered, I think I should say sorry to you." Maca casually said, "Bring you here, I don't just want to fill your soul for you, I also have my own Purpose-Earlier you asked me why I didn't hide and delve into it, right? In fact, the power hidden behind this door might allow me to take a step back and explore the true meaning of the soul rules-while helping you , I am also helping myself. This is what I called "mutual use" at the time."

Having said this, he stared at the door in front of him and blinked, and then suddenly smiled.

"That's it."

"Do you have a way to open the door?" Sarah asked immediately.

"No," Maca shook his head, "You don't need to open the door-I seem to understand. This door may be just a symbol. It's like the power here is just a symbol."

As soon as he finished speaking, he suddenly bends over, gently took Sara's wrist, and slowly pressed the latter's palm to the door of the room.

"Put your hands on it, this should help you feel the'power' there more easily-close your eyes and relax, don't resist, try to feel it."

After helping Sarah to do all this, Maca immediately followed her and closed her eyes slightly, and two people stood there quietly touching the door of the room with their hands.

Time passed bit by bit, and the surroundings were quiet and there was no sound, as if the whole world was moving away from them.

Before she knew it, Sarah only felt that her consciousness, which had been so clear since she was "born", was slowly blurred here.

"This...what...feeling."

After a while, Maca couldn't help but opened her eyes slightly and glanced at Sarah beside her.Then, he couldn't help raising his eyebrows to himself.

"So fast?" He whispered to himself, "Well, although it is a'flaw', but after all, it is a pure and incomparable soul created by peak alchemy-the'door lock' will not do much to her Function. In comparison, I am more like a failure."

Obviously, Maca has indeed understood the nature of this door and the "lock" on the door.

In fact, the so-called "door lock" is derived from the "lock" in the heart of every person standing in front of the door trying to enter.When you think it is locked, then it is locked. The more defensive people are, the harder it is to enter the "door".

And a pure and transparent soul like Sarah might not need the guidance of Maca just now, and he could enter it by accident.

But for Maca, this is a bit difficult.

"The idea is right, there is nothing wrong with bringing her here," he looked at the closed door and couldn't help sighing, "I just missed a bit...this door, I might not open it... …Even if you already understand its principle."

"unless--"

Suddenly, he retracted his hand, looked down at his palm and thought about it secretly.
