Because as soon as she saw the black lake, the red-haired girl felt extremely uncomfortable, and as soon as she approached the shore of the lake, the four droplets of water in her right palm were faintly restless.

Last night, upon hearing Kechelli's staccato descriptions, Catherine suspected that Voldemort had a large number of Yin Corpses in the lake, dead bodies with dark magic that could do what the caster wanted.

But after seeing this black lake, Catherine realized that Voldemort did not simply use this lake as a storage place for Yin corpses, he even arranged a magic circle at the bottom of the lake to transform dead corpses into Yin corpses, the purpose of which was obviously to completely turn the intruders who peeked at the Horcruxes into guards of the locket.

It's just that after these twelve years of desolation, the energy of the magic array at the bottom of the lake has been almost exhausted, so the others didn't notice it, but even so, it is not easy to destroy it by ordinary means.

After all, wizards have always lived on land, and the vision and balance control in the water are completely different from the ground, and although the Yin corpse is a human before death, it is no longer bound by the habits of life after death, so fighting in the water, the former is completely convenient for the latter to divide and attack.

However, Catherine had already been approved by the "lake" during her trip to the Americas, and if she wanted to, she could even destroy these yin corpses in the lake by herself, but the movement was too big for her to explain the reason, and the traces left were too obvious, once Voldemort returned to this cave, she would definitely be able to understand her strength.

So Catherine didn't tell what she had discovered, but lowered her head and silently considered a way to destroy the transformation magic array at the bottom of the lake.

"The ship is over here." Perhaps because he had already been here twice, Kecheli was not as surprised or wary as the others, he just walked quickly along the shore of the lake.

The Slytherins cautiously followed behind the Crcelli, but the Gryffindors remained skeptical, using their magic to detect their surroundings as they went, accidentally alarming the corpses in the lake.

With a loud explosion, a large white creature leaped up from the pitch-black lake twenty feet away. Without waiting for others to see clearly, there was another bang, and it disappeared into the water, splashing a large area of deep ripples.

Harry jumped back in shock, slamming against the rock wall; Draco's face turned pale, and he tightened his wand; Lupin and Sirius' faces were unusually ugly, and it was clear that the situation was completely beyond their imagination; Only the Malfoys and Catherine's expressions remained the same, and it was clear that there was more than one person who knew the situation in advance.

"It's here!" Kecheli snapped out, and snapped his fingers to struck a ray of light into an empty space, where a thick green copper chain appeared. It stretches all the way to the depths of the bottom of the lake.

Kecelli walked over and tapped the copper chain, which began to slide like a snake and quickly coiled up on the ground, and then a small boat glowing green slowly emerged from the surface of the lake and floated towards the shore, barely causing a ripple.

Before the boat could reach the shore, several rays of magic flew by, surrounding the boat, and at last even the Malfoys' faces became ugly.

"What's going on?", Harry asked Draco in a whisper.

"I don't know. I can only recognize that it seems to have something to do with magic. Draco replied hesitantly.

"It does have something to do with it," Lucius explained, "and the magic that the Dark Lord has set up is able to test the magic of the boat-riders and ensure that only one person can pass through the lake at a time. ”

"I'm afraid only Harry is left out here." Lupin said after looking back at the three children. "Just as he ignored the magic of house-elves, he agreed to turn a blind eye to minors."

"But we can't let Harry and one of us pass! That's too dangerous. Sirius protested loudly, and the crowd couldn't help but fall into deep thought.

Catherine crept over to Kechelli and crouched down to whisper something in his ear. Kecheli was stunned for a moment, and saw that Catherine had already grasped his hand, so he had to snap his fingers. Disappear from the shore with her.

"What's going on?" Sirius and Narcissa hurriedly called out to Kecheli, but only the house-elf was back on the shore.

"Where's Catherine?" Sirius grabbed Kechelli's shoulder and shook it violently.

"Miss Catherine asked me to take her to an island in the middle of the lake," replied Kirchley in a shrill voice, "and she said that Dobby would not know the coordinates until she went first." ”

It sounds reasonable, but-

"If you take Dobby first, won't you be able to let him know the coordinates as well?" Harry asked, puzzled, and Kechelli immediately felt stupid, and he immediately threw himself to the ground, slamming his head into the ground.

"Stop!" Narcissa shouted to stop Kecheli's actions, "Take us to Catherine's side first." ”

The two elves did not dare to slack off, and divided into three times to bring the six wizards on the shore to the island in the middle of the lake.

The island was about the size of Dumbledore's office, a flat black slab of empty stone with only a base for a stone basin filled with an emerald green liquid that glowed green.

The first to arrive were Narcissa and Draco, followed by Lupin and Harry, and when they arrived, Catherine was pointing her wand at the stone basin and muttering something, but when she saw them, the red-haired girl stopped.

"Dobby!" As soon as Catherine shouted, her house-elf ran quickly to her, "Go outside now, get a ......," she crouched down and commanded in Dobby's ear.

Dobby nodded and disappeared as soon as he heard this.

When Lucius and Sirius arrived, the crowd gathered around the stone basin, but after figuring out the liquid inside, the faces of the adults suddenly became more and more ugly, especially Narcissa, who was already in tears.

"What the hell are these things?" Harry, who didn't know why, asked nervously.

"I can't say for sure what it is, but it's not poison and doesn't kill people instantly, but the effect is much more terrifying than death." Catherine frowned and explained, "It will completely disturb a person's mental state, produce hallucinations of strictness, and make people feel extremely painful and even lose all abilities. The red-haired girl let out a long sigh, "In other words, if there is only one person, there is no way to leave here at all, and you can only watch yourself being dragged into the lake by the Yin corpse and drowned." ”

"Regulus!" When Sirius heard this, he couldn't help but shout at the Black Lake, and Kecheli hit his head on the ground again, ready to punish himself again.

Another petrification spell fell on Kechelli, only this time it was not Catherine but Lupin who stopped him: "The most important thing now is to find the remains of Regulus." ”

"I'll drink!" Sirius shouted and rushed towards the stone basin, only to be stopped by Lucius.

"There's no rule that you have to be drunk." Before Lucius could finish speaking, Dobby appeared in front of everyone with a dog.

"Dobby, feed the dog the potion in the basin." Catherine took out a cup and handed it to Dobby, then asked the only person who had experienced it, "Kechelli, are you sure that as soon as the potion is drunk, the Yin corpse will appear?" ”

"Yes!" Cutchelli, who had just been lifted from the petrification spell, immediately nodded vigorously.

"Spread the guard!" Lucius began to arrange, "Kecheli, you follow Narcissa; Draco, you follow me; As for you—" He looked at Catherine, obviously prepared for her to proceed.

"Harry follows Remus, Sirius, I'm with you." Catherine said, taking out seven or eight one-liter glass bottles from her pocket and distributing them to everyone, "Gasoline, if you pour it on the surface of the lake and light it, it will burn automatically, and you can save mana." ”

"Much more thoughtful than Lucius." Narcissa smiled and beckoned to get two bottles, then turned to the east side of the island.

"You know his character." Lucius raised an eyebrow as Draco spontaneously walked south with two bottles.

"I've been a wizard for a long time, and my vision has become limited." Lupin took a bottle and sighed, "Well, this Traceless Expansion Charm is good. Harry couldn't help but pick up the bottle he had just arrived and looked at it carefully.

"It seems that I really can't treat you as a mere minor." Sirius picked up a bottle of gasoline and felt a lot of thoughts for a moment.

"Never underestimate a child." Catherine led the way to the west of the island and poured gasoline into the lake along the edge of the stone slab.

After everyone had poured the gasoline into the lake, Dobby fed the potion about the same, and the calm surface of the lake rippled a little.

"The potion has been drunk!" Dobby's shout was like an announcement, and the surface of the lake immediately stirred violently, and countless white heads and hands emerged from the black water.

"Put away the things in the stone basin and the dog!" Catherine shouted at Dobby, throwing out a flash of fire, and the others also lit the gasoline poured on the surface of the lake, and a ring of fire immediately surrounded the island in the middle of the lake, completely blocking the Yin corpses from the outside, and several Yin corpses that were close to them were quickly burned to black.

Seeing this, everyone's hearts couldn't help but settle down, and they began to look around to find the body of Regulus.

"There it is!" Dobby, who was standing on the edge of the stone basin, suddenly pointed to the north of the island and shouted, and everyone looked over, and sure enough, they saw a yin corpse that looked like Sirius.

"Regulus!" Sirius and Narcissa screamed and tried to rush over, completely oblivious to the flames around them, but fortunately they were stopped by Lupin and Lucius in time.

"Master Regulus!" With a startled exclamation, Kecheli appeared next to the corpse that looked like Sirius, and led him back to the island in the middle of the lake.

"It's all petrified!" "Hurry up and be imprisoned!"

Before the corpse that had been taken to the island in the middle of the lake by Kechelli could react, it was struck by several spells, and then fell straight to the ground.

"He has completely turned into a yin corpse and can only be cremated." After Lupin examined, he shook his head and said. (To be continued......)
