A few minutes later, Calvin returned to the door of his office.

Calvin took out his wand and added all kinds of defensive magic to himself: Iron Armor Charm, Crystallization Charm, Dragonskin Charm. He took out a bunch of defensive type alchemy products, and then commanded a tree guard cauldron to open the door.

Fortunately, there was nothing serious in the office, and dozens of civets bared their teeth at the fainted Cedric. It doesn't understand, isn't this man a student of the master, why attack it?

Seeing Calvin returning, Amor took the clone back and meowed. Calvin looked at it with some reproach, and Amor was also aggrieved, obviously it was this student who attacked it first.

Calvin shifted Cedric to the couch and made sure he wasn't hurt in any other way, before he went to the bookshelf and took out a piece of drawing paper from the innermost part of the shelf, from which he retrieved the crystal bottle containing the crown.

The sealing rune on the cap of the crystal bottle was intact, and it seemed that no one had touched the bottle.

Calvin breathed a sigh of relief and turned to look at the unconscious Cedric.

He placed his wand on Cedric's temple, pulled out a silver-white ribbon, and placed it in the meditation ball. Calvin sees Cedric running towards the Fantastic Beasts classroom and being attacked from behind in a dark corner. After that, the picture was blurry, and I couldn't see anything clearly.

Calvin frowned slightly, there was only one possibility for this to happen: the Imperius Curse.

"Tom, it seems that you are so weak that you don't even have the most basic sense?" Calvin held the crystal bottle in one hand and slowly admired the crown inside, "It stole it from me and used the Unforgivable Charm on my favorite student...... You're really dizzy. ”

"So, what should I do with you......" Calvin looked at the crown in his hand, momentarily embarrassed.

It was the only safe research material he had in his possession, and he couldn't bear to destroy it, but keeping it would keep Voldemort in mind. It's a Reaver curse this time, but what about next time? Voldemort, the dark wizard, would not kidnap the students to blackmail him?

Calvin didn't dare to rule out this possibility, given Voldemort's current health and level of madness, he might have kidnapped an entire grade of students as hostages. The opportunity is not impossible, and after Christmas he takes his students to classes in the reserve.

That is, he must settle the matter before the end of Christmas, either by solving the Horcruxes or by dealing with the undercover agents hiding in the castle.

Calvin couldn't make up his mind for a while, he himself was inclined to choose the latter, but it might affect Dumbledore's plans.

"Ugh." Calvin decided to ask Dumbledore for his opinion, and he took out his parchment, wrote down that Cedric had been cast a Imperius curse, and asked Dumbledore when he planned to close the net. Have the Patronus bring the note to Dumbledore.

Soon Fawkes sent a letter back, telling him not to act rashly.

Calvin looked at the note helplessly, wearing dragon skin gloves to take the crown out of the crystal bottle, and kept playing with it.

Calvin remembered every rust, every notch, every stain on the crown, but he was still not sure how to restore the Ravenclaw relic.

Calvin watched for about 10 minutes, and finally put the crown back into the crystal bottle, and used his wand to modify Cedric's memory. Tell Amor to pour Cedric a cup of hot cocoa when he wakes up, and he himself goes straight to the eighth floor of the castle, opposite the giant tapestry.

Calvin held the crystal bottle in front of the blank wall and muttered: I need to see a lab that is absolutely safe. After walking back and forth three times, an intricately patterned door appeared on the wall, and Calvin quickly pushed it open and walked in.

After entering the Room of Requirement, Calvin took the Horcrux from the crystal bottle, placed it on the table in the middle of the cabin, and raised his wand at it.

"I'm sorry, Helena. Crown: I'll find a way to compensate you. ”

A blue-white fireball appeared on Calvin's wand, and the fireball grew dramatically, expanding to the size of the pumpkin that Hagrid had planted in an instant.

The fireball constantly emitted blue-white streamers, which jumped around the fireball, gradually forming a huge dragon head that held the fireball in its mouth.

At this point, the fireball felt like it had expanded to its limit, and instead of continuing to grow, it began to shrink regularly, and at the same time, the faucet became more and more complete and clearer.

As if sensing a threat, the crown kept dripping and spinning on the table, and a large amount of black mist emerged from it, forming a young man's face, which looked about the size of Calvin.

"Calvin, let me go! I am willing to give you everything I have, I am willing to honor you as Lord and be your slave! ”

At this time, the fireball had been compressed to the limit, turning into a blazing white point of light in the dragon's mouth.

Voldemort was still begging for mercy, but Calvin ignored it.

“Draconem ignem spirans!” (Dragon's Breath)

Calvin ched the incantation.

"Roar~"

The roar of the fire dragon echoed through the empty house. The dragon's mouth erupted with blue flames, enveloping the Horcruxes. The black mist evaporated rapidly upon contact with the flames.

Voldemort's plea for mercy came to an abrupt halt, and the viscous fragments of his soul were torn, grinded, and vaporized by the dragon's breath. In the end, only a terrible scream remained.

This is the magic that Calvin imitated from the fire dragon - the Dragon's Breath Charm, a fire magic that is as powerful as the Fire Charm, and it is not black magic, the only drawback is that it is too difficult and can easily get out of control.

At the same time, Professor Quirrell, who was still waiting for news from Cedric in the Dark Arts Office, suddenly clutched his head and fell to the ground silently—he couldn't scream in pain.

Instead, from his turban, a scream came out: "Calvin! I'll kill you! ”

Calvin rinsed the ground with the Spring Charm - the table had been reduced to ashes under the Dragon's Breath Curse, then crouched on the ground and rummaged through a cloud of debris to find a few shiny pieces of metal.

This is the last evidence that the Ravenclaw crown ever existed.

Calvin smiled bitterly, as if mocking himself for boasting about Haikou a few months ago. Immediately collected these metal pieces, not only did he fail to do what he promised Helena, but his research on the soul once again fell into a bottleneck.

"Harry, looks like I'm going to have to help you." Calvin muttered to himself. After losing his only Horcrux, Calvin had to choose to help Dumbledore complete his plan, so that Calvin could regain access to the materials he could study.

Calvin left the Room of Need, leaving darkness, evil, and betrayal forever in the unknown hut.
