In the early morning, at the beginning of the spring sun, the faint light passed through the tender four-leaf clover vines on the corner tower window and floated on the solid wood table on the second floor.

Brie was grading the second lesson paper on the left, nodding in satisfaction as he watched the magic of nature flowing on it.

It seems that his teaching has been successful, that both an out-of-tune person like Draco and a naïve person like Harry have mastered the proper way to channel the magic of nature.

However, the paper in the second lesson gave him a headache, and it can be seen that they have a lot of ideas, but they can ......

"It's impossible to want to fly without learning to walk, a simple principle is not well written, is it so difficult to do natural magic?" Brie's tone was skeptical and slightly disgusted.

But I still graded each paper, named the mistakes, and guided the direction.

However, this time he did not schedule the third lesson, because today is the time for the second event of the Triwizard Tournament.

"Goo-goo..."

It's an owl.

Tom still likes to use an owl to write letters to Brie, which he thinks is more ceremonial and highlights the value of the letter's arrival.

Tom also wanted Brie to reply with an owl, as it would allow him to collect the letters of the exchange.

Who made the magic notes reused, Tom was unhappy that Brie's handwriting disappeared on it, which was a bit of their life.

Brie opened the letter, skillfully ignored a large string of flowery characters, and saw the official text below-

My dear Brie, I have searched many places, but the magical materials on the power of space are too scarce, and I have only collected a few of them, hoping to have a preliminary effect on your experiments, and I will continue to search for more materials.

- Don't forget to reply.

The letter was accompanied by a small package.

Brie took out a piece of letter and began to reply, and in a short time sent the owl away, which had been guarding.

"That's not enough." Brie frowned, but ......

Brie pulls out the unicorn's horn, which was given to him by the unicorn in first grade.

"I can only burn you, I hope to capture the space magic."

Brie put away the magic materials and went downstairs, he had to go into the water early today, and Dumbledore should come to urge him later.

……

In the Black Lagoon, Brie looked at Cho Chang, Ron, and Hermione, who had been stunned by Dumbledore's stun spell, without the slightest surprise.

They were the only ones Dumbledore could find.

"Let's go."

Dumbledore led them down with the Levitation Charm and the Bubble Head Charm, and Brie didn't resist.

The water of the Black Lagoon was still chilling, the gurgling of the water sliding up with bubbles, and they followed Dumbledore deeper into the water.

"I've negotiated with the merfolk, and they'll keep them guarded and stand in the way of the warriors."

Soon, Brie saw a ruined building, with many ugly human faces sticking out, they were like deep-sea fish wrapped in flesh, except for the shape of a human on the upper body, the rest did not conform to human aesthetics at all.

"Some Slytherin snakes are looking forward to seeing merfolk through the glass of the common room," said Brie. ”

Perhaps it was the fairy tales of the human world that caused the little snake to hallucinate that mermaids were beautiful creatures.

Dumbledore chuckled, and soon came to a ruined platform, and when he waved his wand, the aquatic weeds that grew out of the platform's silt grew wildly, entangling the four Brie underwater.

"Hope you won't be bored, Ode."

Dumbledore waved his hand at Brie, and a stream of air erupted from under his robes, dragging him up to the surface of the lake.

Brie looked up, and the streamer crossed Brie's face, and Dumbledore had turned into a small dot.

The sparkling water surface shone down the scattered beams of light, and the refraction was very beautiful.

It's a pity that the light is not at the end, the black lake is as deep as an abyssal valley, and even if the mermaid does not live at the bottom, it is a little dim here.

"Gollum—" Several merfolk with simple but very sharp spears approached, forming a circle around the four of them, but they looked a little disgusted.

Until I saw Brie.

"Goo..."

The merfolk bowed their heads.

And Brie also untied the shackles brought by the aquatic plants and broke the bubble head spell.

The magic of nature stretched out in an instant, and the surrounding lake was under the influence of the magic to methodically form a barrier according to Brie's arrangement, isolating itself.

The mermaid didn't dare to look at Brie, let alone look at the Forbidden Forest contract that Brie took out.

It wasn't until Brie sensed the direction from the contractor and found the location of the Slytherin Chamber of Secrets that the merfolk looked up and looked at each other in fear.

"Coo-goo-goo-goo......" can't be careless......

"Coo-coo...... "I'm going to fulfill the Hogwarts request......

One of the merfolk said fearfully, not daring to pretend in front of the cloth, and it immediately swam out with its spear in the direction of where the warriors had gone into the water.

"Goo-Goo......

The soles of Brie's feet formed a deep blue, like waves wrapped in the wind, and they carried him forward at the bottom of the lake, stirring up a blister around him.

Under Brie's powerful control, the blister lit up again, like a light bulb, illuminating the darkness in front of him.

It's too deep here.

There are rubbles and wreckage everywhere.

Lifeless.

A huge underwater thrust rushed in, and the rocks were all pushed down by this force.

Brie seemed to be surrounded by a pair of large guards, and the force was torn in half by him.

"It turns out that the giant squid of the Black Lake is here."

The squid had just spotted Brie, but it had no idea of greeting Brie, and stretched out its tentacles to its own devices, as if trying to catch Brie and send him back to shore.

The giant squid will send the little wizard back to the water, apparently suffering from an occupational illness.

Illusion Charm.

Brie cast a spell on himself and dived into the darkness, and the giant squid was dumbfounded, and it quickly wandered around with nothing to do.

"Found it, right ahead." With the Forbidden Forest Pact in hand, Brie soon found an underwater mountain range, and as the mountain range climbed, the surroundings gradually became brighter, and some aquatic weeds and fish and shrimp also appeared.

Hogwarts Castle in front of you!

Brie also saw Slytherin's crystal glass window.

The mountain has also reached its peak, and it is as if a barrier has been set up, and ordinary people can only reach it through the rocky area under the water.

"Sure enough, there's a statue of Ravenclaw."

At the top of the mountain, a statue looking in the direction of Slytherin stood still, different from the Ravenclaw common room, which was smaller and more fitting to the Ravenclaw crown.

Around the statue, there were huge chains, which could not be seen at the bottom of the mountain, but when they reached the top of the mountain, they saw that four huge chains were firmly attached to the mountain.

The source of the chains is at the foot of the Ravenclaw statue.

Ravenclaw seemed to welcome Brie's arrival, and the undercurrent swelled underneath, and four huge chains rose and fell as if breathing, knocking against the mountain with a muffled humming sound.

"Lady Ravenclaw."

Brie whispered, lifted up by the current, to the side of the statue.

The statue here was exquisite, with ornate carvings, and Brie could feel that it was an alchemical product, not an ordinary statue, very different from the statues in the Ravenclaw lounge, which were only symbolic.

It has powerful magic.

Brie wasn't sure if putting the crown on it would activate her powers.

"You've found her anyway."

Helena's voice suddenly appeared, accompanied by a ripple of water, and she, as a ghost, appeared in front of Brie's eyes.

"I felt someone touch her."

Helena's eyes flashed with sentimentality, and she slowly approached the statue, and when she couldn't touch it, she reluctantly withdrew her hand.

"It's an alchemical product created by Ravenclaw herself, but if you look closely, you'll see that she's separate from the chains under her feet, and they're not one."

Brie crouched down and lightly touched the chains, indeed noticing that the magic of the chains and the statues was somewhat different.

In contrast, the chains are made in a more rugged way, more like they were made by a man.

"The chains are a product of Gryffindor, and the statue here was originally a Gryffindor."

Helena covered her forehead, her cold eyes slightly furrowed, and her expression was painful.

"I totally remembered." For a long time, Helena took a deep breath and struggled out of the pain.

She looked at Brie in a complicated way, then at the statue, and then at Slytherin in the distance.

"Slytherin left Hogwarts to prove his way."

"Gryffindor soon followed his path and left Hogwarts......"

Helena paused for a moment, and she said to Brie with a little helplessness, "Put the crown on her."

"The truth... Not in my mouth. ”

Brie took the crown out and said, "What's going to happen, I don't want a monster to be released." ”

"No, it won't hurt you, and it won't hurt Hogwarts."

"Actually, the crown should have been worn here a long time ago, but... I forgot. Helena smiled bitterly to herself.

Hearing this, Brie stopped what he was doing.

"There's a guy's soul in the crown, are you sure you want to wear it here all the time?"

Soul?

Helena furrowed her eyebrows, but quickly said, "It only takes a year for the crown to be taken off again..."

"And the soul inside will not live for more than a year."

"The activation of this statue is not something that Tom Riddle can stop."

"It's Lord Voldemort, Lady Gray." Brie corrects Helena's mistake.

Helena was stunned, and surprise seemed to flash on her cold face, but she quickly understood.

"Indeed, he used the failed magic that Slytherin had studied, and he was no longer the same person he used to be."

Slytherin's Failed Magic, which is the Immortal Magic adapted from the House-Elf Crafting Magic.

Flying away from the trap of death, from Voldemort's ancestors.

Brie looked at the crown in his hand, it was a Horcrux he had acquired when he was in his second grade, and of course, it was also a treasure left behind by Ravenclaw, which was said to increase wisdom.

It's a pity that Brie disdains such intelligence, he doesn't think he needs something outside to deceive himself.

"I hope the truth is valuable, or I'll take the crown off."

Brie threw out the crown, impartially, and landed on top of Ravenclaw's head......
