Hogwarts: I have graduated before the system came

After receiving the materials provided by Dumbledore, Douglas re-studied the teleportation array model. With the assistance of Dobby and Sirius, after several experiments, he produced a new teleportation array model. Call it the secret door.

Just after the Easter holiday exams, Dumbledore called the four deans and Douglas to the office.

"Douglas has prepared a new training secret, and we need several people to make their own arrangements in it."

Upon hearing Dumbledore's words, several deans suddenly felt a little dizzy and looked at Douglas with dissatisfaction.

The layout of a Slytherin Chamber of Secrets cost them a lot of energy, and they had to make new adjustments every time based on students' feedback. Not finished here yet, a new training secret realm has been created.

Even if it weren't for the class representative system, which allowed them to hand over some lower grade papers and assignments for marking, it would be difficult to find time to come over now.

Professor McGonagall rubbed her forehead and said:

"The current Slytherin Chamber of Secrets is enough for those students. They can pass through it, which has surpassed many people in the wizarding world.

After all, all the professors there have done their best to decorate it. If they create a secret realm again, let alone whether the professors' energy can keep up, wouldn't it be a bit redundant to ask them to clear the level twice with the same thing? "

Snape said with a cold face:

"I think some people are too leisurely. Or do you think our dean is as leisurely as you?"

Dumbledore did not explain, but took a glass of thick honey water and drank it while looking at Douglas.

Douglas smiled awkwardly and said:

"This secret realm is a bit special. It won't take up too much of everyone's time. All we need to do is make some arrangements... Let's talk about the details after everyone has passed there."

Sprout said from the side: "Douglas is also for the good of Hogwarts. Isn't his achievement obvious to all?"

In the heart of Hogwarts, a unique building. This is a huge oriental pagoda - the Demon Suppression Tower. Its existence breaks the usual Western architectural style of Hogwarts and makes the entire campus full of exotic style.

The appearance design of the Demon Suppression Tower is unique. Each brick and stone is carved with complex dragon and phoenix patterns, showing the delicacy and magnificence of oriental architecture.

The red lanterns hung on the tower during Christmas have not been taken off. At night, the red lanterns will light up automatically, making the tower stand out in the dark. At the same time, the four walls will turn red, giving people a mysterious and mysterious feeling. Weird feeling.

Arriving at the door under the tower, Dumbledore noticed some more runes on the door. Although he didn't recognize most of them, he still managed to recognize some of the familiar ancient runes as space runes. He suddenly had new expectations for this trip, which seemed to be different from the previous teleportation array mode.

Snape's gloomy face:

"Is this the secret realm you mentioned? Do you plan to suppress us in it just like you did with Peeves?"

Douglas laughed and said:

"If it's convenient for the professor, you can also let me try to see if the Demon Suppression Tower can accommodate you, the master of magic."

Snape snorted.

Other professors were also a little curious. Professor Flitwick looked at the runes on it carefully and said in surprise:

"I once studied the Diagon Alley door behind the Leaky Cauldron. The runes on yours are similar to the ones above. Is this teleportation magic? This copper door knocker?"

He did not touch the door knocker rashly, but took out his wand and clicked it, detecting magic fluctuations on it.

Douglas was not too surprised by this. Diagon Alley itself is underground in London, and the entrance to the Leaky Cauldron is on the street in London. Every time you open the door in a fixed way, you will directly enter Diagon Alley. This is only fixed. The teleportation array can do it.

In order to study the teleportation array, he looked for space magic research in this world, so there would naturally be similarities.

Douglas blinked, and then said with a smile: "Of course it's not what the professor guessed, I am a Hufflepuff."

Professor Sprout, who had been silent, his eyes lit up and he looked at Douglas with relief.

Douglas pulled up the left door knocker, and a magic power was transmitted to the copper door knocker through his hand. He picked up the door knocker and knocked it according to a certain rhythm, as if he was really knocking on the door with a specific code.

Immediately afterwards, the runes on the door began to flicker, and then the entire door turned into a light blue illusory shadow.

At the same time, after a wave of undetectable magic power swept over, the right door knocker, which had become illusory, seemed to have been cast a splitting spell, and six rings flew out of each person's hands.

"Tap to the rhythm of the phrase 'Voldemort is Tom Riddle', and the teleportation array will be activated.

The function of the ring is not only to allow the holder to pass through this door, but also an important prop to return from there, otherwise he will be trapped in the secret realm. "

As he spoke, Douglas put the ring on his wrist like a bracelet.

Then he stepped directly towards the illusory door.

Others also followed Douglas's actions, put on the rings and stepped through the door.

The only difference was that Professor Snape got the wand in advance.

As soon as they stepped over, everyone smelled the salty smell of the sea. Looking back, they appeared in front of a rock wall. There were traces of a door on the rock wall, and there was a circular groove in the middle of the door. It was obvious that when returning, just put the ring in it.

Professor Flitwick said in surprise:

"Are we coming to the beach? I thought the secret realm would be underground in Hogwarts."

Douglas did not rush to answer Professor Flitwick's question, but explained to Dumbledore:

"Don't worry that someone will use this knocker to sneak into Hogwarts. This knocker itself is made of magic power, and only those who leave traces there can use it.

As for whether someone will use the Confusion Curse, the Imperius Curse or the Polyjuice Potion to sneak into Hogwarts, let me leave it at that. I will explain it when we return. "
