Hogwarts: I have graduated before the system came

cave.

After controlling all the corpses, the electricity in the lake gradually faded, and after ensuring that there were no other creatures in the lake, several people crossed the lake and came to the island in the middle of the lake.

After stepping on the island in the middle of the lake, a stone basin similar to a pensieve emits a faint blue light, with a base underneath, like a lamp.

Standing side by side in front of the stone basins and looking inside, the basin was full of emerald green liquid, emitting sparkling phosphorescence.

At this time Kreacher rushed into the lake again, groping for the location according to his memory.

As for whether Regulus has turned into a ghoul, everyone is not worried at all. The formation of a ghoul needs to be manipulated by a black wizard through black magic summoning. Obviously, Regulus does not have this condition.

When Kreacher went into the water, Sirius also jumped into the water, but he got out of the water within a minute after going down.

"The luminous spell cannot be used below. There seems to be a force in the lake that limits the luminous spell."

Douglas snapped his fingers casually, and saw a clear spring appear out of thin air and flow towards the ground, but when it was close to the ground, that clear spring suddenly disappeared out of thin air.

"Not only in the lake, but also on this island in the middle of the lake. For example, you can't drink water here. I think most of the measures in the lake should be aimed at the corpses. Voldemort wants to Give them a suitable living environment, and the magic that can last for such a long time has not been destroyed by the lightning just now, and it is estimated that there are only potions... His potion class is very good?"

Halfway through the conversation, Douglas looked at Dumbledore and asked suspiciously. He found that Voldemort really liked to use potions.

Dumbledore, who was detecting the liquid in the basin, also choked on Douglas' sudden question.

"Yes, Tom's grades in Potions were excellent, and it's hard to imagine how much my old colleague Horace Slughorn liked him.

Oh, by the way, Horace was the former Head of Slytherin and the Potions professor. Last Christmas, after your new book launch, he wrote me a letter, saying that he admired you very much, and asked if I could Invite you to dinner, I forgot about it..."

"..."

After seeing Lupine summon a ball of flame to illuminate Sirius and Kreacher in the lake, Douglas didn't intervene in that matter anymore, and continued to study the ball of potion.

He put his hand in...

"Boss, no, don't touch it, let Dobby come..."

"Shut up! Non-Newtonian fluid?"

Dumbledore asked suspiciously, "What?"

Dobby explained proudly from the side:

"Non-Newtonian fluid is a kind of fluid in the Muggle world that does not conform to the law of motion of Newtonian fluid. Its viscosity (resistance) is not constant, but changes with the change of stress. In simple terms, the viscosity of non-Newtonian fluid depends on the stress The manner and intensity of application...

Newton was an alchemist in the Muggle world, of course the Muggles don't call him that..."

Dumbledore said with a smile: "Thank you Dobby... I didn't expect you to know so much about Muggles."

Douglas shook his head again and said: "No, my hands can't touch the liquid at all, it's directly blocked by the air..."

Immediately afterwards Douglas took out the Magic Radar again...

After Dumbledore saw the magic radar, his first reaction was to glance at the lake behind him. This thing should find someone faster, right?

Soon the radar interface displayed a schematic diagram of the entire island in the center of the lake, with lines of various colors intersecting each other.

Obviously, Voldemort magically connected the entire lake island into a whole.

Then he put away the magic radar and said: "I won't do it here, I think Professor Snape will be very interested in this place, so let's leave it to him. There is nothing special about this potion. become weaker..."

Dumbledore nodded and said:

"I think Tom doesn't want people who land on this island to die immediately, he will let them live for a period of time, so that he can figure out how they got through his defenses, and more importantly, why they came here , after all, in his arrangement, he believes that he is the only one who knows the existence of Horcruxes."

Douglas laughed disdainfully: "It's a pity that he ignored the magic of the house elves, so Regulus took advantage of the loophole. If Regulus had come in through the normal way at that time, he probably would have discovered his own magic soon. The Horcrux is lost."

While the two were discussing, Kreacher and Sirius came out of the lake at the same time. Their faces were covered with water, and it was hard to tell whether it was lake water or tears. Sirius was holding a dead body in his arms...

Dumbledore and Douglas looked solemnly, looking at the young corpse, perhaps because of the special effect of the lake water, he still maintained his appearance when he was alive.

His black hair was covered with mud, and with the ticking of the lake, there was still a mocking smile on his pale face. skin, using a spell to untie his tightly clenched fist, revealing a Black family crest...

Kreacher knelt beside Regulus and slammed his head on the stone slab, but did not stop him at this moment...

Sirius silently cleaned the mud off his younger brother's body bit by bit.

Several other people watched the behavior of the two quietly. After Sirius cleaned up Regulus, Dumbledore waved his wand, and a Slytherin banner was summoned, and it was gently placed on Regulus. On Les...

Now that they found Regulus, they didn't stay in the cave. Douglas used the sarcophagus to put Regulus' remains in it. This move made Kreacher look grateful again.

Returning to the entrance hall again, Douglas said: "Sirius, I suggest that Regulus be buried here, what do you think? And he will not be alone, there will be more victims from the beginning, and we will be together." Come and be his companion, and let future generations admire his deeds."

Sirius nodded, his eyes still red and said:

"Well, I don't want him to be polluted by the dirty ancestral grave of the Black family, he is a good boy...you shut up."

Sirius' last sentence directly interrupted Kreacher's rebuttal.

Douglas opened a hole in the middle of the southeast of the rock wall and placed the sarcophagus in. At the same time, Sirius, Lupine, Dumbledore, and Douglas attached their own protection magic to the hole in the wall.

When he was done, Douglas carved a bust of Regulus Black out of a large rock, with a line written on the base.

[Reculus Arcturus Black (1961-1979)

The first person to discover the secret of Voldemort's creation of the Horcrux and intend to destroy it.
