Hogwarts: I have graduated before the system came

While Douglas was explaining, Snape looked around sharply.

I found myself on the platform of a cave. There seemed to be steps leading down on one side. There was a stone statue placed in front of the other two walls. It didn't look like an exquisite relic.

He looked back at Douglas with disdain, wondering if this guy wanted everyone to set up secret games in such a bare place.

Douglas led everyone to the side with steps first. It was the high tide at this time, and the seawater had already submerged half of the steps through the secret passage.

Douglas snapped his fingers, and a ball of light quickly fell into the sea water. Everyone saw the entrance to a secret passage that was only three feet wide.

"I have placed an anti-Apparition spell on the entire cave. This secret passage was originally the only way to enter here, but now I have placed various magic mechanisms inside.

It doesn't look like much at ordinary times, and seawater can flow in and out normally. Once a wizard enters from the outside, various magic traps inside will be activated.

Especially in the middle of the secret passage, I placed a large piece of Forbidden Demon Stone... Well, Professor, you can reimburse me for this later..."

Dumbledore's half-moon glasses couldn't help shaking up and down. If the other four deans weren't here, he really wanted to ask this guy, why did he finish all the materials he gave him so quickly?

Douglas blinked happily and continued:

"The magic trap in the first half of the passage can only be used to restrict ordinary wizards and Muggles. On the one hand, it prevents ordinary wizards from entering by mistake, and on the other hand, it also paralyzes Voldemort who comes in..."

Others frowned when they heard this title.

Professor Flitwick quickly interrupted:

"Wait, why did the mysterious man enter here?"

Professor McGonagall glanced sharply at Dumbledore and Douglas.

"You mean, the so-called secret realm is to let children deal with Voldemort?"

Professor Sprout also said solemnly:

"Douglas, I can't stand on your side this time. It would be fine if it was just a game set by the professors, but the mysterious man... But, Minerva, you don't have to worry. After all, although the mysterious man is still He’s not dead, but he may not come here. I think this place is quite hidden..."

Douglas glanced at everyone, especially Snape's sarcastic expression, feeling very uncomfortable, and then looked at Dumbledore.

Dumbledore pursed his lips and smiled, then looked up at the ceiling of the cave, as if there was some magic there that could be studied.

"Actually, this is Voldemort's treasure cave, so he will definitely come back here, but there is no need to worry about the safety of the students.

The magic trap I just mentioned has another effect. Once the Forbidden Demon Stone is triggered, two Dragon Breaking Stones will fall down within a certain range in front and behind.

Although the dragon-breaking stone looks similar to an ordinary stone, I have burned the magic-forbidden runes on it. Although the effect is not as good as the real magic-forbidden stone, it can cut off the connection with any object, whether it is material or spiritual. .

Although the effect of the forbidden magic stone is not as good as that of the real forbidden magic stone, Voldemort, who has part of his abilities sealed by the forbidden magic stone, will have a hard time escaping from it.

At the same time, the ring worn on the student's wrist will automatically activate the door key function, bringing all students safely back to Hogwarts.

The only drawback is that the teleportation array consumes a lot of magic power and needs to cool down for a period of time before it can be used again. "

Seeing Snape open his mouth slightly, Douglas guessed what the other person wanted to say and said quickly:

"Don't expect those traps to kill Voldemort...the effect of banning magic is less effective on more powerful wizards."

Professor McGonagall said dissatisfiedly:

"Then why not just seal the hole? Then the students will be safe."

Douglas shook his head:

"This is an important place for Voldemort. If he wants to come in, even if you seal the entrance of the cave and use the anti-Apparition/Apparition spell, he might blow up the entire mountain and come in. It's better to leave him alone. A way in."

At this time, everyone's minds were attracted by Douglas's words about Voldemort's treasure cave, and they were all secretly speculating, what kind of treasures, ancient magic, would Voldemort leave behind? dark magic? Or some important magic prop.

If this is the case, it is indeed a good secret realm to train students. Everyone has been there at that age and knows how attractive a powerful wizard's treasure is to young people.

Douglas quickly said to Professor Sprout:

"Professor, can you place some marine magic plants at the entrance of this cave? Although I have set up magic here that can only enter but not exit, those students may not be obedient. It would be better to have some plants to block them. "

Professor Sprout rubbed his hands, looked at the mud under the sea water, and nodded.

At this time Dumbledore finally spoke:

"The point of our visit today is not to discuss this..."
