When Principal Hogwarts and the boy who survived the disaster appeared again, Harry sucked in the cold air at night, which was very humid and filled with the breath of the sea.

A few seconds later, Harry came to his senses and opened his eyes to find that he and Dumbledore were standing in this place, a high black rock exposed to the sea. At their feet, the sea water was shining with cold white light in the night, surging waves, violently slapped the black reef. The momentum was amazing, and the waves rolled up by the rolling waves wet his hair and clothes.

Dumbledore's eyes fell on the cliff. In the darkness, the steep cliff was like a giant beast with a wide mouth. Harry felt the cold water splashing with the smell of sea on his face. The cold made him shrank his shoulders, and he also looked at the cliff, with goose bumps on his body.

"Don't you mind getting your body wet, right? The phantom cannot be transmitted inside."

"It's okay, professor, I learned well in the Goblet of Fire." Harry said and added a spell to himself.

"I didn't bring Fox, but let's take a chance." Dumbledore suddenly became as quick as a young man. He slid gently from the pebble into the sea and swam towards the dark crack on the rock surface. He held his wand in his mouth, in a perfect breaststroke posture.

Harry quickly jumped into the water and swam and followed.

The sea water was extremely cold. After Harry's clothes were soaked in water, they became bulging and heavy, and he pulled him down. He took a few deep breaths, and could smell the pungent smell of salt and seaweed through the bubble spell. He struggled to find the flashing light that was moving deep into the cliff and becoming smaller and smaller.

Soon, the crack turned into a dark secret passage, and Harry could see that the secret passage would definitely be filled with sea water at high tide. The mud-sticked rock walls on both sides were only three feet wide, and under the light of Dumbledore's wand flashed through, it shone like tar. Going in a little further, the secret passage turned left, and Harry saw it stretching to the deepest part of the cliff. He continued to swim forward with Dumbledore, his frozen fingers rubbing against the rough, wet rocks.

Then he saw Dumbledore standing up from the water, his silver-white hair and black robe flashing with water. Harry swam there and found a step leading to a large cave. He climbed up the steps with great effort, and the water flowed down from his wet clothes. He finally walked out of the sea water, and the air around him was silent and cold, and he couldn't help but shivering.

"Fluorescent flashes." Dumbledore raised his wand, and the golden light illuminated the space around them. In the cold and darkness, they struggled to enter the deepest part of the cliff, followed the steps to a large cave, and the air around them was silent and cold.

"You can't be wrong. Someone has tried magic here." Dumbledore held up his wand and rubbed his fingers against the rough and wet rocks.

Harry didn't know whether he was shaking like this because the cold had invaded his bone marrow or because he also realized the existence of the spell. He watched Dumbledore continue to rotate slowly in place, obviously focusing on studying something that Harry couldn't see.

"Harry, I'm sorry, I forgot." Dumbledore pointed his wand with his wand, and the red and yellow flames spurted out from the tip of his wand. Harry's clothes immediately became dry and warm, just like they had been baked in front of a blazing fire, "a warming spell popular over Demstrong."

Before Harry could say his grateful words, he found that the wand that had not yet been withdrawn in Dumbledore's hand gradually shortened and turned into a silver short knife. He waved his knife calmly and cut his palm.

"Professor!" Harry exclaimed.

"If you want to find an entrance, you have to pay a price, a price that can weaken the strength of the visitor."

Harry opened his lips and said it was too late, but he couldn't help saying, "You should let me come, professor."

"No, Harry, your blood is much more precious than mine." Dumbledore wiped his cut palm towards the surface of the rock, and shining dark red blood beads covered with the surface of the rock.

The stones on the rocks rubbed on the blood were shaking off, and the scattered stones piled up on the ground in disorder, revealing a door hole.

"Voldemort will not easily make people discover where he hides his soul." Dumbledore pulled his robe and walked in over the scattered stones. Both his wands were fluorescent. "He will definitely set up precautions and be careful."

Dumbledore stopped Harry, and in front of them was an extremely wide black lake. Dumbledore raised his arms and swung his wand upwards. A bright light flew out from the tip of the wand, flying further and further, falling onto the platform in the middle of the lake.

"The question is how do we get over? We can't... can't we try the flying curse?" Harry's eyes turned around, knowing that it must be a stupid suggestion.

Dumbledore didn't answer, and his feet stepped down, and his brass-buckled shoe tip moved to the outside of the rock edge of the lake. He held a magic wand in his right hand and stretched his five fingers forward with his left hand, as if he was pulling something out of thin air. Although there was no wind in the hole, his sleeves were shaking.

Harry also walked forward two steps, and many bubbles gushed up in the lake, like boiling boiling water. A thick green copper chain suddenly emerged from the depths of the lake and rushed towards Dumbledore's palm, and Dumbledore grabbed it with one hand.

"Do you help Harry." Dumbledore handed the iron chain to Harry. Harry quickly inserted his wand into his pocket, held the copper chain with both hands and pulled it back.

As he pulled, the iron chain hit the rock wall and made a loud echo. The copper chain pulled a white boat up from the dark bottom of the lake. The small boat with the snake-shaped relief bow floated towards the lakeshore like a slightly raised leaf, slowly approaching them without causing a ripples.

"Professor, how did you do it?" Harry asked in surprise.

"Magic always leaves traces," Dumbledore said, and with a slight bang, the boat hit the shore, "and sometimes it's very obvious. I've taught Tom Riddle and know his style."

Dumbledore frowned, his eyes stayed on the chain, "Harry, be careful. Stay alert, there are handprints on the moss in the chain, and it seems that someone has pulled it recently."

Harry heard this and held his wand tightly, but nothing happened in the end. Harry looked down at the boat. It was indeed a very small boat: "It seems not for two people to sit, can we eat and hold on to the weight of us? Will we add up to it too heavy?"

"Tom wouldn't consider the physical weight, he only considered how much magical power had crossed his lake. I think the ship might have been cast with a spell, and could only ride one wizard at a time."

"That……?"

"I don't think you will be counted, Harry, you are not old enough and not qualified yet. Tom would never have thought that a sixteen-year-old boy would come to this place. I think your power is probably negligible compared to my power."

Harry was depressed and Dumbledore probably realized this. He added: "Tom was wrong, Harry, Tom was wrong... The elderly underestimate young people, which is stupid and forgetful... Well, you go first this time, be careful not to touch the water."

The two boarded the boat, and because the small space was forced to squeeze together, they floated calmly to the platform in the middle of the lake. Dumbledore took the lead and Harry followed closely behind.

Harry stared at Dumbledore and reached out to the stone basin, trying to touch the liquid. But he encountered an invisible resistance, and his hands could not get close to the liquid. No matter how hard his hands stretched down, the fingers seemed to touch the extremely hard and indestructible air.

"Do you think the Horcrux is inside, Professor?" Harry watched Dumbledore's wand slowly rub over the liquid in the crystal basin. The potion in the basin bubbled in a boiling manner, and then returned to calm as his wand left.

Dumbledore Dumbledore frowned and sniffed with his nose, as if he smelled something strange, but then stared at the change of the potion in the stone basin, and then he raised his head, "You can't stretch your hand in it, you can't separate it, scoop it dry or suck it all, and you can't use the disappearance spell to make it go away, use magic to deform it, or change its nature in other ways-I have to drink it all, and all drink it all."

"What?" said Harry, "No! But what if...if it poisons you!"

"Oh, I believe it won't have that effect... Voldemort wouldn't be willing to poison the people who came to this island." Dumbledore's expression began to be serious after he said easily, and he looked at Harry's eyes. "Remember to promise me before coming? This potion may paralyze me, may also make me forget the purpose of coming, may make me unable to drink it in pain, and anything else may happen, but you must not obey me, Harry. Your responsibility is to make sure I drink all the potion, even if I force it to pour it open, do you understand?"

"Why can't I drink it, Professor?" Harry couldn't believe it. Did Dumbledore think about the good things so ridiculously? He thought he could not let Dumbledore take this risk.
