This Hogwarts isn't normal.

Dumbledore held the old wand in his mouth and kept diving in a perfect breaststroke posture.

From time to time, he would install a glowing alchemy equipment on the rock wall, and soon he came to the narrow secret passage.

He suddenly put his hands and feet together and drilled into the secret passage in an extremely graceful posture.

Vincent, who was following behind, was stunned.

Harry behind and Sirius behind were also stunned.

The big guy is the big guy, and he doesn't look like an old man over a hundred years old no matter how he looks.

It is better to leave the matter of overcoming obstacles to Dumbledore, and they should follow with peace of mind.

The rock walls of the secret passage were covered with silt, and Vincent, who had a slight obsession with cleanliness, kept adjusting the nozzles of his flying boots to change his posture.

The 3.0 version of the flight boot optimizes the wear process and greatly reduces the noise and vibration caused during flight. It even adds the submarine's ventilation technology, so that it can produce strong thrust underwater.

The ultimate performance naturally brings the ultimate cost.

However, the mass-produced version only needs to control the noise and vibration, and the high price will only discourage the wizards.

The secret passage is winding and rugged, and above the water surface at the end is a slightly wider space.

Dumbledore stood up from the water, his eyes fixed on the two mini puppets floating in front of him.

This space does have magic restrictions, and it is a restriction for remote exploration magic.

He picked up two puppets and stuffed them into his arms, and held his head and saw a step not far away.

Although the steps are a bit rough, they must have been made by man.

Looking up, you can see a large cave.

Vincent rushed out of the water at this time.

He floated in the air, his eyes swept back and forth toward the water that was rippling, as if he was looking for something.

"Professor, have you seen my puppet?"

Dumbledore replied without thinking, "No, I didn't see it."

Vincent narrowed his eyes and stared at his bulging white robe.

This old man forced Deng Zhen to hold a grudge, but the left and right were quite symmetrical.

Harry and Sirius also poked out of the water one after another.

Neither of them understood why the atmosphere around them was a little nervous.

It was not until Vincent looked away and looked at the steps not far away that the strange atmosphere completely disappeared.

The cave above the steps is where Tom "friendly exchanges" with two orphans when he was a child. Such a place with special significance is indeed likely to have a Horcrux placed.

The group climbed the steps, and Dumbledore, who arrived first, stood in the middle of the cave and carefully looked at the rock wall and the top of the cave.

Vincent stood not far behind him and took out the double snake staff from Lemay's ring.

Not only is it a magic restriction, there are also a variety of magic that blocks the six senses here, and there are even some evil auras left by the sacrifice ceremony.

It is too old, but the sacrifice ceremony should be the key to opening the real cave.

Dumbledore drooped his old wand and walked towards the rough rock wall, "This is just the front hall, the entrance hall, we need-"

"We need to find out the keyhole that enters it." Vincent took out a small black ball from Lemay's ring that was not as big as a golden thief.

The surface of the ball is extremely smooth, but it has no metallic luster at all.

He played with the small ball in his hand, "Professor, let's compare who will find the keyhole and key first?"

Dumbledore smiled silently, gently stroked the rough rock wall with his fingertips.

Harry and Sirius finally understood.

This old and young man turned out to be a tantrum.

Dumbledore groped through the rock walls on his own, and Vincent slowly turned the small ball in his hand without waiting for his answer.

The sphere opened a gap with a click, and countless slender red light shone on the rough rock wall.

Dumbledore looked back and then continued to grope along the rock wall quickly.

Vincent turned around in a slow and slow manner, and a red light suddenly flashed on the surface of the small ball.

"Professor, I found it."

Harry and Sirius looked at each other silently.

These two people don’t seem to have bad tempers, at least the search progress has been greatly improved.

Vincent walked towards the small black ball and scanned the abnormal rock wall.

There is a circle near the middle of the rock wall that is vaguely darker than the surrounding area, and this place should be the keyhole.

The three of them walked over quickly.

Dumbledore stretched out his hand and pressed it flat. Vincent pointed the two snake staffs before he could retreat.

The outline of an arch appeared, emitting dazzling white light.

The illusory outline slowly became clearer, but disappeared completely after a few seconds.

Dumbledore stared at the big rock under the rock wall with all his attention, and Vincent took out a black magic book and looked it out.

Harry and Sirius did not dare to disturb the two.

The keyhole was found, but the key has not been found yet.

Two minutes later, Dumbledore muttered softly, "Oh...of course it won't...too low-level..."

Vincent closed the magic book, "I guessed it was indeed a sacrifice ceremony."

Dumbledore looked back at the magic book in his hand, "We need to pay a price to pass here and enter the real cave."

Vincent looked contemptuous, "Tom is so disappointing, I've been looking forward to it for so long."

Dumbledore's tone was also a little contemptuous, "So I said it's too low-level. Blood seems to weaken a person's body, but there are many things in this world that are much more terrifying than the damage caused by the body."

Blood is the medium and sacrifice required for the sacrifice ceremony, and it is also the key to entering the real cave.

Originally, the two thought it would be an evil ritual that sacrificed life or soul. It would be too pediatric to just pay blood.

Dumbledore took out a small short knife that was commonly used in Potions from his robe and then blinked at Vincent.

The latter pretended to look through the magic book in his hand again, obviously not wanting to suffer this loss.

"Uh..." Harry walked forward, "Professor, let me do it."

Dumbledore shook his head, "You are kind, Harry."

He rolled up his sleeves, "But your blood is more valuable than anyone else, there is no need to waste it in such a place."

"But professor, we don't know..."

Sirius held Harry's shoulder and said, "I'll do it."

He picked up the short knife in Dumbledore's hand and clamped the sharp blade with his other hand.

"Wait first." Vincent closed the magic book, "I have an idea, maybe we can't pay the price."

Alchemists always have some weird gadgets on them, and various magical creatures that can improve the quality of the finished product are also a regular product.

But Vincent didn't take out the blood, but a metal bat that could stop magic.

Liquid metal drips on the rock, making a "sizzling" sound.

If the sacrifice ceremony does not exist, that is, the keyhole does not exist, it is equivalent to not requiring a key.

Dumbledore looked at the liquid metal that was swallowing rocks little by little, and couldn't help but smile and sigh,

"Tom was too arrogant. He looked down on many things, thought his arrangement was seamless, and that everything had to follow his ideas."

It seemed to be confirming his words. When the entire rock was swallowed by liquid metal, the hidden arch once again appeared on the rock wall.

Vincent leaned over and turned the liquid metal back into the bat, and the rock that originally needed to drip blood disappeared strangely.

“Times have changed, professor.”

He stood up and looked at the arch that was leading to endless darkness, "Alchemy is developing, magic is developing, and the entire wizard society is developing, and the old things that are outdated are destined to be abandoned by the times."

Dumbledore twitched slightly at the corner of his eyes.

The truth is indeed the case, but he always feels that Vincent is scolding himself in disguise.
