Hogwarts: I have graduated before the system came

Douglas looked at the time and urged: "It's getting late, let's set off quickly, we can't let a hero lie in the icy lake this Christmas."

As soon as these words came out, Kreacher became agitated again. Dobby stepped forward and grabbed Kreacher tightly, which made Kreacher even more agitated... He kept shouting that he was not clean.

In the end, under the fierce scolding of the red-eyed Sirius, Kreacher finally calmed down.

Everyone turned their eyes to Douglas, and he arranged unceremoniously:

"Kreacher, first take Dobby to that place to find out the way, and then you two will come back to pick us up."

As he spoke, he took out a porcelain bottle, handed it to Dobby and said:

"It contains the Dali pill I developed. Using the apparition carrier at such a high frequency will consume a lot of energy. I don't want to have any accidents. Every time you send someone over, you two will take one pill. "

Dobby bowed excitedly and said: "Dobby's boss is really a good man, the boss has always thought about Dobby..."

Kreacher kept his distance from Dobby with disgust. He didn't respond to Douglas's words, but looked at Sirius.

Sirius frowned and said, "Look what I do, you can do what Doug says."

Kreacher shook his big head and muttered, "Oh, Master Sirius told Kreacher to listen to that... that Doug, and Kreacher to listen to Sirius."

After Douglas heard Kreacher's words, he kept biting his molars angrily. When Sirius called himself Doug, his tone was normal, but Kreacher's mouth was full of naked yin and yang.

Just when Kreacher and Dobby came back to pick up Lupine and Sirius, Dumbledore suddenly asked Douglas:

"Douglas, there are no more Horcruxes in that cave. Why do you still have to go there? If you just bring back Regulus, I think Sirius and I will be enough. You don't think Tom will Is there some treasure hidden there?"

Douglas raised his eyebrows and said with a smile: "This involves another teaching plan of mine. Although Hogwarts already has some teaching and experiment bases. But do you think those places are more practical than the cave built by Voldemort? ?”

At this moment, Kreacher and Dobby returned again, and Douglas told them to wait for a while, and then arranged a sound-proof magic shield casually.

Dumbledore was silent for a moment, then nodded.

Douglas continued:

"There is another advantage to doing this. If Voldemort returns again, do you think these students will still tremble when they hear the other's name when they know that they have broken into the Dark Lord's lair?

I hope that no matter what kind of dark wizards my students face in the future, they will not be afraid and stand on the side of justice, instead of shrinking in fear of the opponent's powerful strength. I want to let them know that there is nothing wrong with the opponent.Because they were already playing games in a Dark Lord's lair when they were in school. "

Dumbledore looked at Douglas in silence for a while, then asked with a sudden smile, "And then?"

Douglas immediately showed a flattering smile on his face, took out a parchment from his arms and handed it to Dumbledore, and said with a smile:

"So we need to build a safe and stable transmission channel connecting Hogwarts here. Portkeys cannot be used, and it is easy to be monitored by the Ministry of Magic. Apparation cannot be used. Students do not have this ability.

Coincidentally, I have recently researched a teleportation array that can be used by multiple people, just to build it, it needs some materials, so I hope the school can give me some help. "

Dumbledore took the parchment, looked at the content on it, and suddenly couldn't laugh: "Douglas, can you explain to me that the 200 pounds of fresh dragon's blood are all used to draw the teleportation array? It is the dragon's blood that can draw some symbols. Wen, but it’s not enough to use so much, and this dragon thigh meat... I might as well make some small door keys with your things... You know. We don’t Maybe let the school manager know, so the funds need to be deducted from some regular funds..."

Douglas quickly said: "Professor, the transformation of this practice site will definitely involve several deans. I think Voldemort's magic is also of great research significance to them...

To be honest, only I can get many materials of this transmission card, so some of the above things are equivalent exchanges. "

Dumbledore nodded seriously and said, "Your explanation is perfect, but I have to charge some middleman fees, isn't that reasonable?"

......

In a huge cave, the surrounding area is very empty and humid, the air is filled with the fishy smell of the sea, and the sound of waves crashing against rocks in the distance.

When Dumbledore and Douglas arrived, Lupine and Sirius were already looking around with their wands raised.

Dumbledore also held up his wand to observe the surrounding rock walls and cave roof, and then walked to where Sirius and Lupine were standing. There was a step on the edge of the cave, leading to a dark passage below...

Dumbledore took out a lighter-like extinguisher from his pocket, and after hitting it, a circular light source floated towards the dark passage below.

Then several people clearly saw that the underground passage was very wet, and there was still a lot of mud on the ground.Lupine frowned slightly and said:

"This is not like the entrance of a secret room, but rather like a passage from the outside, and it is connected to the sea. Because it is low tide now, there is no water pouring in."

While several people were studying the passage, Douglas first arranged for Dobby to measure the size of the entire cave platform.

I saw Dobby skillfully took out a magic tape measure from his pocket, threw it casually, and the tape measure began to measure according to Dobby's requirements, and every time he took a measurement, he reported a data to Dobby, and Dobby was serious in his notebook. record.

Douglas sneered at Kreacher, who had been staring at the three of Dumbledore, and Kreacher was visibly relieved when Lupine judged that it was not the entrance. Then he turned his face and saw Staring at Douglas who was sneering at him all the time, Kreacher froze in place for a moment, then shook his head and muttered softly.

In Douglas' view, this old guy was thinking too much. He knew where the entrance was, and even knew how to open it, but he didn't say anything. The purpose was to see if these people could really open the Dark Lord's secret chamber.
