Hogwarts, was gnawed at the beginning

"I think we have to swim. Fortunately, the weather is nice today. It shouldn't be too cold. None of you mind getting wet, right?" Dumbledore looked at everyone.

"Why don't we use magic? I mean, turn into a boat or something." Harry couldn't help but ask.

"Tsk..." Snape let out a mocking sneer.

"Because the outside of this place is shrouded by a layer of invisible magic. You can try to feel if you can mobilize the magic in your body." Sirius glared at Snape, but surprisingly did not quarrel with Snape, but spoke softly. Explain to Harry.

Then he also looked at the dark cracks in the rock wall with complex eyes. Has his brother been there for decades? How lonely must that be.

After hearing Kreacher's story, Sirius's impression of Regulus had changed. Coupled with the close blood connection, Sirius couldn't think of anything else.

What's more, when he was young, Regulus had been following him as a follower.

The emotional ties that really existed in his memory also made Sirius unable to ignore them.

"Wow..." Even though the weather was indeed pretty good, the sea water was still very cold. Accompanied by the pungent smell of sea and seaweed, everyone quickly reached the depths of the crack, which had turned into a dark sea. Secret passage.

The feeling of sluggish magic power disappeared.

Dumbledore released a bright white light ball in the water. It floated precariously on the water, emitting a soft and non-glaring light, lighting up the way forward for everyone.

After swimming forward for a few minutes, Dumbledore in front stood up from the water, his silver hair and black robe shimmering with water.

Everyone quickly gathered on the steps without falling to the ground. Further forward was a dark cave entrance, with a salty sea breeze blowing out from inside.

The first thing you should do after landing is to evaporate the water vapor from your body. Except for people with special habits, no one likes the feeling of being sticky and wet.

"Oh, thank you, Soul." The seawater on Harry's body evaporated into white mist under the influence of magic, and was blown away by the wind blowing outward from the cave.

"You're welcome." Suer smiled slightly and turned to look curiously at the place where His Highness Luo Dan used to store his Horcruxes.

Dumbledore raised his wand high, and the ball of light swayed upwards, shining brightly in mid-air, and the darkness instantly melted when it encountered light.

Old Bee squinted, raised his head, walked slowly, and carefully looked at the rock wall and the cave roof.

"Oh, yes, this is it," he said softly.

"How do you know?" Harry blinked blankly.

"If you look carefully enough and are not a fool like your father, you can see traces of magic being used everywhere here." Snape said coldly.

"You can speak less if you don't know how to speak, Snivellus." Sirius couldn't help it anymore.

Snape slowly turned his head to look at his old enemy with his dead fish eyes. Even though Snape had met the person he thought about day and night with the help of Soul and Dumbledore, he and his Lily is not the only reason for hatred.

Oh, I want them to meet each other without fighting in this life...

I can only restart my life...

"Ahem." Dumbledore said at the right time, "This is just an antechamber, it can only be regarded as an entrance. We still need to go inside. What's blocking us now is no longer an obstacle set by nature, but an obstacle set by Riddle. The trap...well, I think I've found a way in."

"Thul, I want to test you, can you spot it? Of course, Harry, you can also try it."

"I'll give it a try." Suer nodded, closed his eyes, and breathed calmly.

When a normal person closes his eyes, it should be dark, but Sur's eyes light up instead, just like the night imaging ability he was born with after turning into Animagus form.

Of course, this is a magic-using technique derived from a book in the Hufflepuff Lady Heritage.

You know, before Hogwarts was founded, Hufflepuff, Slytherin, Gryffindor and Ravenclaw formed a group to explore and travel in the magical world for a long time. This magic use technique is used in some ruins , very useful when exploring treasure areas.

The light group represented by Dumbledore is dark red, and the two groups of magic power representing Sirius and Snape are similar in color. However, if you look carefully, you can find that Snape's magic power is darker than Sirius's, and Harry's is different from those present. The three adults were as weak as a nascent flame.

Ignoring several groups of light of different brightness around him, Sur turned his 'eyes' to the stone wall not far away. There was a group of light there that was very different from the color of human magic power, and was as dark as the stone wall.

The cloud-like dark magic mass was concentrated on the stone wall in front of him, outlining a shape that looked like a door frame.

"There." Sur opened his eyes and pointed at the stone wall.

Dumbledore's lips curled into a satisfied smile.

Harry, who was frowning and searching for the clue, looked at Soul in shock when he heard this. He found nothing.

"how did you do it?"

"It's very simple, calm down and observe carefully, you will find that there is a big difference between magical items and ordinary items. I remember there is a book in the Hogwarts library--"Get the most from the ruins" You can check it out after you return to school. It’s a very useful method." Suer replied.

"If I were you, Potter, I would put my energy into practicing Occlumency." Snape sneered, "instead of thinking about things of little use all day long."

In fact, this was how he got through tough Potions lessons and private one-on-one lessons.

Sirius could see that Snape was angry with his good brother's son, and a new round of mutual hostility began.

Harry closed his mouth tightly and turned his head to watch Dumbledore's movements.

Dumbledore was too lazy to care about these old enemies. Instead, he raised his wand and waved lightly. The door frame immediately appeared, and the black light flashed, but disappeared again in the blink of an eye.

Obviously, using magic to activate this door is not the right approach.

"Oh..." Dumbledore reacted quickly and chuckled, "That's really low-level. I really overestimated you, Riddle."

"What?" Harry's ears were filled with all kinds of negative comments coming from Snape and Sirius' mouths, and he couldn't hear Dumbledore's words clearly.

"Lu Dan, ah no... the Dark Lord has set a limit on this door." Suer said, "What price must we pay to pass through this door."

This is alchemical knowledge, equivalent exchange.

"That's right." Dumbledore glanced at Soul appreciatively.

"The price?" Harry asked again. He looked at Soul with admiration, deeply aware of the narrowness and poverty of his own knowledge. "What do we have to give this door?"

"According to what I know about Riddle." Dumbledore shook his head slightly, "It should be blood."

"Blood?"

"Yes, it's too low-level." Dumbledore said with contempt and disappointment in his tone, "To enter this door, you must weaken yourself, but obviously, Riddle does not understand that there are many things more terrifying than physical harm. many."

"Can we avoid this?" said Harry.

"Sometimes, some things are unavoidable." Dumbledore shook his head.

"Need blood?" At this time, Sirius pulled out his wand and walked forward, "I'll do it!"

Dumbledore stopped Sirius under Harry's anxious eyes,

"Don't worry, Sirius," he said. "Although the cost is inevitable, we can use a more cunning method."

Snape curled his lips. He could fully understand what Dumbledore meant. He reached out and took out a transparent bottle from the wizard's robe. As a potion master, he was accustomed to hiding some potion materials on his body for easy use. When needed, blood happens to be one of the ingredients for potions. The prerequisite is that the blood must contain magic power.

"Idiot." When passing by Sirius, Snape dropped the sarcastic words, pulled out the cork of the bottle, and used magic to draw the blood out of the bottle with a hint of pain.

To be honest, he really wanted to see Sirius stupidly open a blood vessel and feed blood to this portal.

pity...

This door's appetite is quite big, and fortunately Snape's bottle seems to be quite special. That small bottle contains blood that far exceeds its capacity.

As Snape's expression grew colder, the door finally stopped absorbing, and the invisible doorframe gradually became clear and solid.

The solid rock wall was also replaced by a dark and narrow corridor.

Dumbledore followed suit, using a magic spell to illuminate the corridor like daylight, and followed Dumbledore's steps forward. From this, Soul and the others could clearly see what existed at the end of the corridor.

A big lake, yes, a big lake, and only magic can create a much larger lake in a not-so-big seaside cliff.

The lake was dark and faintly green. Even the magic light source that illuminated them before could not penetrate the lake.

Faintly, Su Er could see that there was a strange and hazy green light flashing in the center of the lake. It was probably like the Mohe he had been to in his previous life, where he had admired the blue aurora, but the 'aurora' here was not at all like that. It's not beautiful, but it makes people feel bad at first glance.

"Let's go." Dumbledore looked at the faint lake, "Be careful, Harry, follow me and don't touch the lake."

Sirius, Snape, and Soul, who was trained by Snape himself, naturally do not need Dumbledore to answer alone.

Several people followed Dumbledore as they walked along the shore of the lake. On one side was a dark, rough rock wall, on the other side was a lake that could not even penetrate the light. Except for the sound of shoes colliding with the rocky road, there was silence.

And such a quiet environment feels very depressing.

"Why don't we try magic? Professor Dumbledore." Harry felt really uncomfortable and hesitated for a long time before speaking.

"For example, turn it into a ship." Harry thought his proposal was great. There might be magic restrictions on the outside, but there shouldn't be any magic restrictions on the inside.

Dumbledore stopped when he heard this, "It's a very good idea, then we might as well give it a try."

As he said that, Old Bee smiled and waved the Elder Wand, and a boat appeared on the lake in an instant, but in Harry's doubtful eyes, the boat sailed empty-handed towards the hazy green in the center of the lake.

The ship conjured by magic had not traveled very far when a loud explosion-like sound suddenly came from the lake.

A big white guy jumped out of the lake and rushed towards the crowd.

Harry was startled, his back pressed against the rock wall, his expression frightened.

Snape chuckled for the first time today.

The pale big guy twisted in the air for half a second, then fell back down, viciously bringing the ship underwater with it.

The ripples spread out in circles, and Harry made a "gudong" sound as he swallowed.

"What's that?" he asked.

"It seems that there is something our savior doesn't know." Snape ruthlessly laughed at Harry's ugliness, "Thul, please give our savior an answer."

Sur, who was suddenly cueed, blinked, but still gave the answer---

"That's the Inferi from Klee's incision, Harry."

"And, according to what Kreacher said..." Soul pulled out his wand and summoned a light ball of the same type as the old bee, commanding it to float above the lake to the place where the ship sank just now, and then slowly sink,

"I'm afraid Voldemort has mastered a huge army of Inferi. What you just saw was just one of them."

The light cannot penetrate the lake because this huge lake is used to support the Inferi Legion. Therefore, due to the influence of the lake, the light ball was extinguished not long after it descended. However, the moment before the light disappeared, it was enough for them to see clearly. , a large pale shadow squirmed in the opposite direction to the light.

Harry gasped and turned pale.

"I think this is one of the purposes of Professor Dumbledore coming here, right?"

"A very reasonable guess." Dumbledore said with a smile. "The Inferi is a very troublesome thing. In order to prevent us from encountering such difficult-to-handle dark magical creatures on the battlefield in the future, I think there is a chance. If you can weaken the effectiveness of our future enemies, I have no reason to refuse."

"Then do we still need to go to the center of the lake?" Harry said.

"Of course, in my judgment, only by triggering the means left by Riddle can we lure out the Inferi." Dumbledore said as he stretched out his hand and gently shook it in the air.

"Oh, I found it."

Dumbledore's hand seemed to have grasped something like a rope, and then, a green copper chain as thick as a baby's arm jumped out of the lake like a snake, tightly wrapped around Dumbledore's body. Clenched fist.

'Ding' The Elder Wand collided with the copper chain and made a crisp sound.

The green copper chain gently slipped through Dumbledore's palm and fell into a pile on the ground. There was faint movement from the dark bottom of the lake.

A small boat suddenly appeared out of the lake like a ghost. The hull of the boat was emitting green light. It appeared quietly and came quietly in front of everyone. The whole process did not cause any ripples on the lake.
