"Flashback spell? This is indeed a good idea."

Grindelwald reacted instantly and nodded in agreement.

At the same time, Dumbledore and Lockhart also nodded in agreement after thinking about it.

It was...passed unanimously?!

Elena was stunned for a few seconds, frowned, and carefully observed everyone's expressions.

This was beyond her expectation. In her original thought, this proposal should force the "murderer" to self-destruct directly.

In the original basilisk encirclement and suppression plan, everyone was likely to cast the "Forgetting Curse".

However, the actual situation now is different from the plan.

If the "Forgetting Curse" appears during the reversal of spells within three days, it will almost 100% be labeled as a "murderer".

"Flashback spell, what is that..."

Hannah whispered, biting Miss Know-It-All's ear.

However, before Hermione could explain, Grindelwald and Elena took action to answer the question.

Grindelwald took the initiative to raise his wand and docked it with Elena's wand.

"Pre-Flashback Curse!"

Elena read softly.

Thick gray smoke came out from where their wands met.

As time goes by, it keeps changing shapes: at first it was some magical plasticity, which was the assembly work of the ternary computer; then it was the pieces of land being laid upside down and paved, which was the repair site they were working on;

After that came the floating spell and the simple transformation spell. Watching the blurry gray ax blade mist falling and rising, everyone present knew what it was doing...

"Disappear without a trace!" Elena waved her magic wand, breaking off the flashback spell's retracement.

The light, shadow and smoke in the air disappeared.

"Then, next, I will be responsible for the retrieval of the flashback spell..."

Grindelwald looked at the other wizards with a strange, meaningful and slightly cruel expression.

No matter who secretly cast the Forgetting Curse on Elena, he would not feel particularly angry. Although this little girl looks shrewd, sometimes, she is still too easy to "show her belly" to the people she trusts. This is not

The qualities that a qualified superior should have.

If we can take this opportunity to let Elena understand some of the cruel nature of the "lonely world"...

Even if one or two people who cross the red line are sacrificed for this, it is not impossible.

"...Isn't it Gale?"

Dumbledore frowned slightly and looked deeply at Grindelwald.

As a result, the situation was more complicated than he imagined.

If Elena was really "attacked", then his attitude and subsequent choices would be particularly important.

Dumbledore knew very well that some things are not just about right or wrong and revenge. When a certain bottom line is inadvertently broken, the sequelae may be more difficult to heal than the scars left by sticking to the bottom line. There is still a long way to go.

…

For a time, all kinds of thoughts in his mind were mixed.

However, Dumbledore did not stop.

Before saving others and Elena's soul, he must first protect himself.

Before Grindelwald could come over, he took out his wand and put it against the tip of Grindelwald's wand.

"Pre-Flashback Curse!"

Grindelwald raised his eyebrows and read clearly.

Gray smoke poured out again.

…………

"Disappear without a trace!"

About a quarter of an hour later.

Grindelwald's originally cruel and joking expression turned into confusion.

He waved his hand and dispersed the smoke pouring from the tip of Hermione's wand in mid-air.

As for the girl's use of curses to copy her homework, and even the explosive curses she secretly tried in the castle, those are things that Dumbledore should worry about and consider in the future. Grindelwald is even more confused now about who is behind the magic spell.

Attacked Elena without knowing it.

"What should I say now? Are there any clues?"

Grindelwald's expression became serious and he looked at the girl not far away who was also deep in thought.

This is not a good thing.

Although the security alert at Hogwarts has always been a place where he teased Dumbledore.

But joking aside, after Elena, himself, Nico Flamel and other wizards worked together to reinforce it, Hogwarts Castle is not only impregnable, it is at least one of the most difficult places to sneak into in the wizarding world today.

Not to mention the "sneak attack" incident.

"No more, maybe there is Nico Flamel...but I don't think he has the ability to subdue us instantly."

Elena shook her head slowly, biting her fingers in confusion, "So are we going to seal off Hogwarts Castle? Search the castle from beginning to end? Or search the Hyperion? It's a joke, but that's the next best thing,

The collapse of trust is even more terrifying, but where did the problem go..."

"Well, actually there is another possibility..."

At this moment, Hannah said cautiously.

After such a long period of buffering, she roughly figured out what happened.

"Huh? For example?" Elena tilted her head and looked at Hannah expectantly.

"We were not checking the wand just now to determine who cast the 'Forgetting Curse' on you."

Hannah glanced at Dumbledore and the solemn-looking Grindelwald, and blinked.

"So, if all the wands present have to be checked, isn't it that Elena's own wand has not been checked?"

"So... you think I will chant a curse on myself?"

Elena said quite speechlessly, and couldn't help but roll her eyes.

Such a fool, she didn't know what to say.

Except for the accident in Lockhart's original work, who normal wizard would cast the Oblivion Curse on himself?

You must know that one of the reasons why the Forgetting Curse is not considered black magic is that it has clear and multiple methods of resolving the curse. The most common one is of course that the caster takes the initiative to restore the erased memories, and some powerful people

Wizards can also recover on their own.

For example, in the original novel, Bertha Jorkins was cast an oblivion spell by Barty Crouch Sr.

However, if the caster and recipient of the spell are the same person...then the only way to restore this memory is to wait for a miracle.

"In that case, why not give it a try?"

Grindelwald said softly, extending his wand forward and looking at Elena thoughtfully.

"Alright alright"

Elena shrugged helplessly.

She raised her wand and pointed it at the tip of Grindelwald's wand again.

Of course, she did not forget that she had two wands. She also took out the other wand from her arms and pointed it at the tip of Dumbledore's wand.

"Pre-Flashback Curse!"

"Pre-Flashback Curse!"

Dumbledore and Grindelwald said in unison.

Immediately afterwards, two groups of gray mist quickly poured out along the junction between Elena's wand and their wands.

"Seal down Hogwarts. When I find that guy, I will kill him"

Elena admired her magic spell, her tone as cold as ice without any ups and downs.

until……

The gray mist gradually deforms.

Finally, it condensed into a miniature version of Elena.

She saw "herself" raising the wand and pointing it at "herself"'s forehead.

"Everything is forgotten."
