Harry glared at Dumbledore unwillingly, and his heart felt like a pot. He didn't understand why Dumbledore had reacted the way he did, had he instructed Snape to find out what Malfoy was doing, had he heard what he was talking about, or was he actually worried and just pretending to be nothing?

"So, sir!" said Harbour, in what he hoped would be polite, calm voice, "you still trust ......."

"Alright, Harry, I've been tolerant enough to answer the question. Dumbledore said, but his tone was no longer tolerant, "My answer hasn't changed, and now, I think we should focus back on the matter at hand." ”

Harry looked blankly at Dumbledore and then back at Aven, hoping for help.

Implicit in Dumbledore's tone was that the topic was over, and he didn't want to discuss Malfoy's assassination of him or whether Snape could be trusted.

He certainly trusted Snape and knew Malfoy's actions inside and out, there was no doubt about it.

Truth be told, Evan wanted to ask Dumbledore what he was going to do.

But in the end, he didn't say anything, and looking at Dumbledore's expression, he knew that he would not answer the question, and now was not the time to say such a thing.

In the minutes following the end of this topic, the atmosphere was slightly dreary.

The surrounding environment also made everyone not want to talk too much, for fear of disturbing the rest of the souls of these already house-elves.

And just like that, they finally stopped in front of the row of shelves full of mutilated house-elf heads.

This is the entrance to the Demon Altar, and the shelf of the house-elf heads has an eerie pale blue skin, more or less missing or damaged, like the faces of mad-eyed men, glaring at Evan viciously with their big, scary bulb-like eyes.

The heads on the shelves weren't just hurt, they had some kind of haunting hatred on their faces.

This kind of look should not be seen in a submissive creature like a house-elf, and now that it has appeared, it looks particularly weird.

No one spoke, and even Harry stopped thinking too much about Dumbledore and Snape and Malfoy.

The sound of nervous heartbeats and even breathing was unusually clear in the quiet and treacherous atmosphere.

"These house-elves have suffered in their lifetimes!" Dumbledore whispered, "Alright, back off, we need to crack the magic trap left here." ”

As he spoke, he took out his wand and tapped it on the head of a house-elf cadre.

Bang, bang, bang, as if knocking on the door, the elf's closed eyes snapped open......

It looked at the six men in front of it fiercely, its mouth opening and closing, as if to eat them alive.

Elaine let out a low scream, then hurriedly covered her mouth and hid behind Hermione.

Because she had been here before, Hermione was prepared, and her stiff body still betrayed her.

Evan was used to it, and Harry and Ron, who were beside him, were very pale.

The moment the eyes of the dried corpse heads of the house-keeping elves opened, their heartbeats also increased sharply, but they could still hold on. But when the gloomy green ghostly fires appeared in front of him and flew towards them, Ron couldn't help but shout.

Dumbledore swung his wand hard, and all the ghostly fire vanished.

"Interesting, interesting. He whispered, as if he had discovered something interesting.

"What's interesting, Professor?" asked Aven.

"Do you know what magic this is, do you have an impression of the magic just now?" Dumbledore asked rhetorically.

"Not impressed, Professor. Evan thought for a moment and said, "It just feels weird." ”

That's right, it's just weird.

The last time he came, he felt very strange, whether it was the fluctuations in the magic around him or the magic.

"Strange of course, because it's not magic cast by a wizard. Dumbledore said.

What does it mean that it's not a magic cast by a wizard?

Is it the magic of the house-elves, or is it the magic of the demon below?

After a poignant sound, the entire shelf slid to the right to reveal the space behind it. They walked in one by one, Dumbledore being the first, his right hand covered in strange spells holding his wand held high in the air, and the wand glowed with a bright white light that dispelled all darkness.

Behind him, Harry, Ron, Evan, Hermione, Elaine walked in the back.

The staircase goes down, and the ground, the off-sides, and the surrounding walls are covered in large blocks of black rock.

The rocks were black, cold, and eerie, and they seemed to merge into one, absorbing all the light.

But Dumbledore's right hand holding his wand high was steady, and the light from the end of the wand grew stronger.

The darkness was dispelled, but the temperature around it was getting colder and colder, and it was unstoppable.

Soon, they will be spewing white mist as they breathe.

It was close to the center of the Demon Altar, and the ground was covered in a thin layer of ice.

It's not just the ground, everything as far as the eye can see glows with a strange pale cyan sheen.

This is the color of frost, and this is the world of ice.

Ai Wen couldn't help but guess if the source of the cold air in the cold storage of the ingredients above was this place.

Even though it's December and everyone's robes are thick, the cold seems to reach the heart.

Aven's wand swiped over himself, Hermione, Elaine, Harry, and Ron in turn, using magic to keep warm.

Dumbledore didn't do anything, he didn't seem to feel the cold, and was staring at the end of the stairs.

There, everything was shiny, and the black rocks were covered in a thick layer of ice, which in turn formed strange shapes.

It was a wall of ice, accompanied by rich magic fluctuations, and a cyan blue halo flashed from time to time behind the ice wall.

"Be careful!" Dumbledore said, walking on.

The passage that Evan had entered had last been covered in ice again, leaving no trace.

A white mist erupted from the end of Dumbledore's wand, and soon the thick wall of ice melted into an entrance.

Inside, the Demon Altar glows blue and appears to be made entirely of frost.

The altar is made of dozens of huge stones stacked in a concentric circle shape, and it looks particularly grandiose.

Each stone was a huge rectangle, standing upright above the ground, about ten feet high, and between the adjacent stones was joined by another rock across the top, in varying numbers and directions, or across two or three or four pieces, arranged together in a peculiar pattern.

The stone blocks are not smooth and complete, and there are grooves of different shapes scattered irregularly on them.

Each groove is inlaid with precious stones, which are divided into cyan and blue, giving off a faint brilliance.

If you get closer, you can see that there are complex magical patterns of light blue between the gems, and from time to time there is a flash of light on them......
