From Beauxbatons to Hogwarts

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

Calvin took out his wand and blessed himself with various defensive spells: Iron Armor Curse, Crystallization Curse, and Dragon Skin Curse.He took out a bunch of defensive alchemy products and then commanded a Bowtruckle to open the door.

Fortunately, nothing serious happened in the office. Dozens of civet cats bared their teeth at the unconscious Cedric.It doesn't understand. Isn't this person a student of its master? Why is it attacking it?

Seeing Calvin back, Amor took back his clone and meowed.Calvin looked at it reproachfully, and Armor also felt aggrieved. It was obviously the student who attacked it first.

Calvin moved Cedric to the sofa and made sure that he was not harmed. Then he came to the bookshelf, took out a piece of drawing paper from the innermost side of the bookshelf, and took out the crystal bottle containing the crown.

The sealing runes on the cap of the crystal bottle were 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 put it into the meditation ball.Calvin saw Cedric running towards the Magical Creatures classroom in the screen, and was attacked from behind at a dark corner.The picture after that was blurry and nothing could be seen clearly.

Calvin frowned slightly. Generally, there was only one possibility for this situation: 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, "You actually stole it on my head. Yes, and you also used the Unforgivable Curse on my favorite student... You are really out of your mind."

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

This was the only safe research material in his hand and he couldn't bear to destroy it, but if he kept it, Voldemort would always be thinking about it.This time it’s still the Imperius Curse, but what about next time?Will Voldemort, a dark wizard, kidnap students to blackmail him?

Calvin did not dare to rule out this possibility. With Voldemort's current health condition and level of madness, he might kidnap an entire grade of students as hostages.The opportunity is not impossible. After Christmas, he will take his students to the reserve for classes.

In other words, he must solve the matter before the end of Christmas, either by solving the Horcrux or by solving the undercover agent hiding in the castle.

Calvin couldn't make up his mind for a moment. He himself tended to choose the latter, but it might affect Dumbledore's plan.

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

Soon a reply came from Fox, asking him not to act rashly.

Calvin looked at the note helplessly. He took out the crown from the crystal bottle wearing dragon leather gloves and kept playing with it.

Calvin clearly remembered every rust, every scratch, and every stain on the crown, but he was still not sure about repairing this relic left by Ravenclaw.

Calvin looked at it for about 10 minutes, and finally made up his mind, put the crown back into the crystal bottle, and used the wand to modify Cedric's memory.He asked Armor to pour him a cup of hot cocoa when Cedric woke up, and he went straight to the eighth floor of the castle, opposite the giant tapestry.

Calvin held the crystal bottle and muttered silently in front of the blank wall: I need to see an absolutely safe laboratory.After walking back and forth three times, a door with complex patterns appeared on the wall. Calvin quickly opened the door and walked in.

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

"I'm sorry, Helena. I will find a way to compensate you for the crown."

A blue-white fireball appeared on Calvin's wand. The fireball grew rapidly, and in an instant it expanded to the size of a pumpkin planted by Hagrid.

The fireball continued to emit blue-white streamers. These streamers jumped around the fireball, gradually forming a huge dragon head that held the fireball in its mouth.

At this time, the fireball felt that it had expanded to the limit. It no longer continued to grow, but began to shrink regularly. At the same time, the faucet became more complete and clearer.

The crown seemed to feel threatened, and kept spinning on the table. A large amount of black mist came out from it, forming the face of a young man, who looked about the same age as Calvin.

"Calvin, let me go! I am willing to give you everything I have, and I am willing to respect you as my master and be your slave!"

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

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

"Draconemignemspirans!" (Fire Dragon Breath)

Calvin chanted the spell.

"roar~"

The roar of the fire dragon spread throughout the empty room, causing waves of echoes.The dragon's mouth spit out blue flames and enveloped the Horcrux.The black mist evaporates quickly after touching these flames.

Voldemort's begging for mercy stopped abruptly, and the sticky soul fragments were continuously torn, ground, and evaporated by the dragon's breath.In the end, only a shrill scream was still echoing.

This is the magic that Calvin imitated from the fire dragon - the Dragon's Breath Curse. It is a fire magic that is as powerful as the Fire Curse, and it is not a black magic. The only disadvantage 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 hugged his head and fell to the ground silently - he was in too much pain to cry out.

Instead, a scream came from his turban: "Calvin! I'm going to kill you!"

Calvin washed the ground with the Clear Spring Curse - the table just now was reduced to ashes under the Dragon's Breath Curse. Then he squatted on the ground and dug out a few shiny metal remains from a pile of debris.

This is the last evidence that Ravenclaw's diadem ever existed.

Calvin smiled bitterly, as if he was mocking himself for boasting so much a few months ago.Then he collected these metal blocks. Not only did he fail to fulfill his promise to Helena, but his research on the soul once again fell into a bottleneck.

"Harry, it seems I have to help you." Calvin said to himself.After losing his only Horcrux, Calvin had to choose to help Dumbledore and complete his plan. Only in this way can Calvin regain the materials for research.

Calvin left the Room of Requirement, leaving darkness, evil and betrayal in that unknown cabin forever.
