Entering the doorway, under the light of magic manufacturing, everyone found themselves standing on the shore of a large black lake, they saw a very strange scene in front of them, and the size judged from the outside, the whole cave seemed to be cast a very clever traceless expansion spell, the lake was extremely wide, as far as the eye could see, the cave to which it belonged was very high, and they could not see the top of the cave when they looked up, they walked around the shore of the lake, stepped on the rock and made a crackling sound, this footstep broke the silence in the darkness.

Allen, who had taken a few steps forward, stopped, as if sensing something special, he waved his arm, and the light from the "fluorescent flicker" flew slowly towards the middle of the lake, illuminating the middle of the lake high, and everyone looked at the light,

"That's it. After Alan finished speaking, the fluorescent light that he knew illuminated the middle of the lake and floated on it, reflected in the dead water below, except for the fluorescent light and the bright light from the two wands, and there was a complete darkness that could not be dissolved.

Sirius looked at the dark lake, put away the mess he had just had with Alan, he felt the necromantic aura coming from it and clenched his fists - his brother Regulus was dragged into the lake by those yin corpses, and now his only thought was to find Regulus, no longer let him soak in this pool of cold water, even if he was rotten to bones, and take him home.

Sirius's gaze and the house-elf Kreacher on the side just collided, and the two people who disliked each other had a common idea at this time, and this somewhat reckless tacit understanding made them not hostile to each other for the first time in a long time.

"Regulus is in the lake, I'm going to find him!" Sirius retracted his gaze and cast a bubble spell on himself, a large bubble of air covering his head like a goldfish bowl upside down in his head.

"Master Regulus! Kreacher has come to pick you up!" Kreacher moved to the outermost part of the edge of the rock, and said hoarsely in his bullfrog voice, swaying back and forth with his arched body, ready to jump straight into the dark depths of the lake.

"My apprentice's beard! I'm fed up!" Allen, who had just looked at the middle of the lake and heard the movement, saw the scene in front of him, just like the mysterious man who had watched the news report after the Ministry of Magic war, he waved his hand heavily, and directly pushed the two guys back into the air with a magic spell and fell to the ground.

Sirius got up, frowned and looked at Allen, "Why did you stop me from picking up my brother?"

Hermione also felt a little embarrassed as a Gryffindor, and she looked at Sirius and Kreacher's expressions as if Harry and Ron had done something stupid again: "It's all corpses down there! If you don't mind, I'll have to watch you two next, lest you two come up with some clever plan that will kill us all!"

"It's just a Yin corpse! I can solve it!" Sirius was a little unconvinced, feeling that he was an adult, and as an elite member of the Order of the Phoenix, he was underestimated by the little girl, "The Yin corpse is afraid of fire and light, and my magic flame can burn in the fire!"

Kreacher didn't say much, it wasn't that he had any change in his opinion of the Muggle-born Hermione, he was just afraid that he would be sent back at this time and would not be able to participate in the next action, he didn't know Alan's temper, he just tried to show what a good house-elf should do, and it was best not to let them notice his existence if the master didn't make a sound.

"And then?!!Burn your brother too?" Hermione raised an eyebrow, "How are you going to quickly tell who your brother is inside, and how do you get him out of the environment full of corpses alone?"

"If Lily were alive, you must have had a lot in common with her. Sirius opened his mouth, and finally muttered with memory, and then his eyes lit up, "Maybe we should try to summon the spell?

With a loud explosion, a large white creature leaped up from the pitch-black lake twenty feet away. Sirius only came to look at it in a hurry, and with a bang, it disappeared again, splashing a large deep ripple on the calm water, and this spell was relieved by Eren as soon as Sirius cast its effect, and Alan's ability startled Sirius.

But before he could say anything, after seeing Allen's eyes that were a little bulging, he knew that this must be a stupid act in the eyes of the other party, although he didn't want to admit it, he also knew that he was a bad person who loved to act before he thought, and his current partner was not a member of the 'predator' who shared his hobbies.

"Don't use any spells!Any!Do you think the Mysterio would be stupid enough not to think about anyone trying to use a summoning spell directly? The act of summoning something with a summoning spell will only cause one or more Yin Corpses to fly out of the water to block the effect of the spell, and if the water surface is disturbed, the Yin Corpses will also climb up to the surface and try to drag the intruder into the water. Alan sarcastically said to Sirius, who felt that he was prone to high blood pressure after staying with the other party for a long time or even at a young age.

"Can you comprehend an unfamiliar or unique magical effect with just your eyes, like Dumbledore?" Sirius was surprised to hear such a specific explanation, even if he didn't like to learn very much, but his good family education still gave him enough vision to know that to achieve this level meant that the wizard was no longer just a user of magic spells like ordinary wizards, but had a certain level of achievement in studying the essence of magic.

"Listen... I'm sorry, but you have to calm down, the spells laid by the mysterious people here will make the intruders who are dragged into the water turn into new Yin Corpses..."Alan pressed Sirius in advance, but was surprised to find that he didn't have any of the violent reactions he imagined, "These Yin Corpses are controlled by the spells on the pedestal in the center, we have to deal with it first, so that the control of the out-of-control Yin Corpses can easily be seized by some of my subordinates using their innate abilities." ”

"Those necromantic bodyguards of yours, you'd better not get too caught up in necromantic dark magic, there are quite a few people in my family because of this... Forget it, you won't listen to me anyway..."Sirius shrugged, stretched out his arm, and pointed to the center of the smooth mirror-like lake, which looked endless, but the green light was flashing in the center, "I just looked at it and knew it wasn't Regulus, as long as I could save him, I would listen to you, the question is how do we get there?"

Kreacher said there was a boat. Hermione raised her glowing wand aloft to find the boat, but in the thick darkness she couldn't get anything for a moment.

"It's easier to find out after you've read a few pages. ”

As she spoke, Allen's hand was placed on Hermione's right hand holding the wand, letting it slide slowly through the air, as if trying to find and grasp something invisible, and after a few seconds, Hermione found the place under Allen's guidance, and she closed her hand and grabbed something in the air that neither she nor Sirius could see, and slowly moved towards the lake.

Alan also stretched out his palm, and the lake rolled over, and immediately a thick green copper chain suddenly emerged from the depths of the lake, and before the female companion could catch it, it rushed towards his clenched fist, and then he casually threw it to Sirius and cleaned it up for himself one by one, "Excuse me." ”

Sirius's lips moved, and he held back the words into motivation, and began to work honestly as coolies.

The chain began to slide through Sirius' hand like a serpent, and gradually coiled up on the ground. The clanging sound slammed against the rock face, making a loud echo, and the chain dragged something up from the bottom of the pitch-black lake.

The bow of a small boat suddenly emerged from the surface of the lake like a ghost, glowing green like a chain, and floated towards the shore of the lake where they were, barely causing a ripple.
