Lupin was confused, of course he could recognize that Ivan had given him a wolf poison potion, but today was not a full moon, how could he become a wolf?

But he didn't have time to ask, for there was a light fog on the lake, and Sirius and Ivan, who were in the boat, had disappeared in front of him.

......

At the same time, the boat was silent, moving smoothly on the lake, as if pulled by an invisible rope, and automatically approached the middle of the lake without paddling.

No one dared to speak all the way, everyone was worried about disturbing the corpses in the lake, the surroundings were dim and scary, only a faint green light could be seen flickering from time to time in the distance.

Sirius stood tall in the ship with his wand held high, lighting the way forward.

Ivan next to him was very interested in this small boat, sitting on the bow of the boat and slowly stroking the hull, the touch was wet and very slippery.

Even with his current level of alchemy, he couldn't see how the ship worked, and perhaps Voldemort didn't use alchemy to create it, but used his powerful magic to enchant the ship to some extent.

As Ivan studied, the boat's speed suddenly became slower and slower.

"We're here!" Sirius lowered his voice and whispered.

Ivan looked ahead, and through the fog he saw a smooth, rocky island rising in the middle of the lake.

It looked about the size of a classroom, and it was empty, except for a pedestal more than a meter high, which was very conspicuous, and on the pedestal was a stone basin, from which the green fluorescence was transmitted.

Ivan's figure flickered, but the boat under him slowly stopped.

Sirius took the lead and stepped onto the island, towards the central stone basin, and Ivan thought about it, and quickly followed.

"Is that what Regulus drank from this kind of thing?" Sirius muttered as he looked at the stone basin, gazing at the phosphorescent emerald green liquid in the basin.

Just by looking at the appearance, you can tell that this thing is poisonous, and it is not pleasant to drink!

"Yes... Master Regulus ordered Kreacher to oversee him drink all the potions...", the old house-elf sobbed lowly, recalling the scene in his mind.

Sirius was silent for a moment, his eyes fixed on the other locket in the basin. "If Regulus took out the Horcrux, why did he make the same thing and put it back?"

"Probably trying to confuse Voldemort? Trick him into believing that his Horcruxes still exist, so that Voldemort wouldn't have made more Horcreats and died in a battle. Ivan said as he analyzed the note that Regulus had left in the fake locket in the original plane.

Unfortunately, Regulus's plan fell through, Kreacher had no ability to destroy Voldemort's Horcruxes, and if he hadn't shown up, the fake Horcruxes placed here would have pitted Dumbledore into it.

Thinking of this, Ivan couldn't help but shake his head, Regulus arranged all this with his life but accidentally pitted the friendly army, the old professor was also miserable enough, he got a Xibei after so much torture...

Sirius glanced deeply at the stone basin, but did not touch it, and turned to look at the house-elf who was still sobbing and spoke.

"Kreacher, take me to the place where Regulus was dragged down the lake."

Kreacher nodded sharply, leading Sirius towards the left side of the island.

Ivan didn't rush to follow, hesitated, waved his wand slightly, and a faint fluorescence appeared on the ground at the base of the stone basin, which were linked to each other and converged into a line of words, and soon fell silent again.

There, he unleashed a trigger-type magic that would manifest whenever someone approached the text, alerting the comer.

lest Dumbledore find this place all the way after they were gone.

Of course, it is also possible that Voldemort will see it, which will be very interesting.

Ivan smiled and turned away without hesitation.

At this time, Sirius was crouching on the ground with a serious expression, the wrist of his left hand was slashed, and a large amount of blood dripped to the ground, which was drawn into a strange pattern.

Ivan stood quietly and watched the scene, not surprised.

Sirius had told him that his brothers were connected by blood, and that he could use a spell to strengthen that connection for a short time, so that he could locate Regulus.

However, this is obviously a kind of dark magic, and it is not known which book Sirius is from which it is seen, so it seems to be quite restrictive, otherwise Sirius would not have had to go to this island to complete the ritual.

It took about two minutes for Sirius to draw the pattern, press his right hand on it, and muttered an obscure incantation.

The blood on the ground reacted immediately, and it climbed all the way down the palm of his hand as if it were alive, converging into an identical pattern on the back of Sirius's hand, which looked like a blood-colored tattoo, glowing red.

"Great, he's still here!" Sirius's body trembled, and he said excitedly.

The success of the magic proves that Regulus's body is still there, and it is well preserved, not torn to pieces by the Yin corpses and melted into the lake, otherwise it would not be inaccessible.

Sirius couldn't contain his excitement, he cast a bubble head charm on himself, and then clenched his wand and plunged headlong into the dark lake.

Ivan didn't even have time to stop it, and slapped his forehead helplessly.

In his opinion, before going to the lake, at least discuss the coping strategies for encountering various crises, and then check whether there are any problems in the lake... And not so recklessly past...

But by this time Kreacher had already jumped off the lake, and was too far away to find anyone, so Ivan had to go down with him.

"It's cold!"

When his body was submerged in the lake, Ivan immediately felt that something was wrong, and it was summer, but the water in the black lake was as cold as winter.

And it was pitch black all around, and he could only vaguely see something in front of him.

"Lumos~" Ivan waved his wand slightly, and a flash of light lit up from the tip of the wand and spread out in all directions.

Ivan, who saw his surroundings clearly, was suddenly startled, and across him was a corpse, a male corpse with open eyes to be exact.

Ivan could clearly see the slightly swollen face, which was soaked and slightly puffy, and the eyes that bulged out more than ordinary people, and those eyes were staring at him.

Ivan almost launched an attack, but fortunately, after he remembered in time that he drank the potion, he was similar to the Yin corpse in terms of physical characteristics, and the other party should not attack him, otherwise he would have pounced on him.

Thinking of this, Ivan was a little relieved, he tried to get closer, but the latter didn't make any movement, as if he was really dead,

It wasn't until he got close enough that the Yin Corpse moved, trembled a little, and then sank straight down.

Ivan thought for a moment, it seemed that what Lupin said was not wrong, the Yin corpse couldn't help but be afraid of the heat, and also afraid of the light.

Confirming this, Ivan didn't bother with the other party, and tried to swim towards another dark spot of light in the black lake, the Yin Corpse does not use magic, this light must have been made by Sirius.

The closer they got, the more Yin corpses around them became.

There were all kinds of corpses of men, women, old people, and children, and apparently he had guessed correctly, Voldemort must have slaughtered a Muggle town, otherwise the British wizarding world alone would not have been able to gather so many corpses.

And these yin corpses were scattered or densely floating in the lake, motionless.

Ivan swam forward, carefully keeping an eye on the Yin corpses around him, sometimes even having to push away some of the blocks or pass through the middle of several Yin corpses.

In this way, I don't know how long later, when Ivan's hands and feet were numb from the cold, he finally saw Sirius.

He was not far ahead, and the mark on the back of his right hand was glowing blood-red, indicating that Regulus's body was nearby.

However, this magic was obviously not accurate, so Sirius was forced to swim in front of the Yin corpses and check their faces.

Ivan also helped in the search, holding his wand and relying on the faint light to discern every face as far as his eye could see.

While looking at them, Ivan noticed that all the Yin corpses seemed to be staring at him and Sirius, and the pair of swollen faces and sunken eyes were very mad.

He understood that this was due to the Light Charm, which attracted the attention of these Yin Corpses, but their IQ was very low, and they could not determine that they were alive, so they fell into such a state of failure.

Ivan couldn't be sure when the corpses would find out that something was wrong and pounce on them, and he couldn't stop releasing the magic spell of the lighting, so he could only choose to speed up.

Sirius had shown him a portrait of Regulus before he came, and if he hadn't been disfigured by the lake, he would still be able to tell the difference.

"Master Regulus!"

As Ivan made a closer look, a faint, indistinct voice reached his ears, and Ivan jerked his head to see that it was Kreacher who made the sound.

This old house-elf doesn't know what magic it uses, and it can stay underwater for so long without using the Bubble Head Charm, and it can even open its mouth to speak.

However, Ivan didn't pay attention to this now, because Kreacher had clearly discovered something, and was very excited to swim forward.

Ivan followed without hesitation, and saw Kreacher in the distance hugging a corpse at the bottom of the lake.

It was a young male corpse, lying quietly at the bottom of the lake, motionless, wearing a dark green robe and a conspicuous black badge pinned to his chest.

It was only when Ivan got closer to see that it was Blake's family crest, consisting of a five-pointed star and a dagger shield embedded in it, and two leaping greyhounds standing next to it.

With this alone, Ivan was able to confirm that this was Regulus!

Although he found someone, he didn't have any happy mood, and Sirius next to him couldn't be happy at all, because Regulus, like those Yin Corpses, had his eyes open, staring at them, staring at the light!

Ivan immediately understood that the last thing they wanted to see had happened, Regulus had been transformed into a Yin corpse!

Sirius's body trembled slightly, I don't know whether it was anger or disbelief, but fortunately, there was no point of anger and loss of reason, and he opened his mouth to make Kreacher quickly let go.

It's just that they were a step slower, and Regulus, who had been as motionless as a corpse, suddenly moved after being hugged by Kreacher, and his swollen white hands grabbed the neck of the house-elf like iron pincers.

Kreacher was patronizing and excited, and was completely defenseless against Regulus, and did not even resist after being choked by the neck, but felt that this was Young Master Regulus's punishment for himself.

But in the past few decades, Regulus, who has been completely transformed into a Yin corpse, does not know what it means to keep his hands.

Kreacher quickly rolled his eyes in a pinch, and the magic that had been blessed on his body could not be maintained and collapsed, and a large amount of lake water poured directly into it from his mouth and nose.

“Petrificus Totalus ！ Seeing that the situation was critical, Sirius immediately paused the release of the Light Charm and instead waved his wand quickly.

A white beam of light struck Regulus through the water.

Regulus's originally white, puffy skin suddenly turned gray, and he maintained his original position, and the movements of his hands stopped.

Ivan seized the opportunity to grab Kreacher and save it from Regulus's grasp, and cast a bubble head charm on it in time to prevent it from drowning.

However, the situation did not improve, Sirius's attack on Regulus was like triggering a taboo, and the stagnant corpses around him suddenly became agitated.

Several Yin Corpses, which were very close to Sirius, stretched out their hands and grabbed his clothes and arms, and more Yin Corpses swam towards Ivan with hideous faces.

Ivan was very anxious, he understood that Sirius's release of magic to attack the Yin Corps must have triggered some kind of restriction, and now the Yin Corpses no longer regarded them as their own kind.

“Sectumsempra... Ivan waved his wand to cast a spell to save Sirius, but the latter shook his head at him, and said something with his mouth wrapped in the bubble head spell.

Close your eyes! Ivan read the word from Sirius's mouth, and he immediately reacted and closed his eyes.

The next moment, an incomparably dazzling light lit up from the tip of Sirius' wand, like a supernova shining in the dark universe, and Ivan could feel how intense the light was with his eyes closed.

The Yin Corpses that bound Sirius loosened him, and the hundreds of Yin Corpses that had been rushing towards them fled in the opposite direction in fear.

When the light faded, Ivan opened his eyes and found that there were no other Yin corpses around him except for the petrified Regulus.

Ivan couldn't help but sigh that Sirius was reckless, in the end he was still a little anxious, he couldn't cast a fire spell underwater, but a greatly enhanced fluorescent flicker could also have the effect of dispelling the yin corpse.
