I need an explanation, Miss Kaslana. Dumbledore said in a deep voice.

"Now? Probably...... Not quite right?" said Elena, glancing at the few little witches around her.

"Yes, now, if you have any doubts......"

Dumbledore's fingers tapped lightly on the tabletop, and although the surrounding environment did not change, the distance between him and Elena became quiet in an instant, and an invisible layer of magic enveloped him and Elena.

Even though they were close, the three Hermione couldn't hear Elena and Dumbledore's voices at all - they couldn't even see the shape of their mouths, as if a fog had suddenly covered everyone's eyes.

At the same time, Dumbledore's gentle voice rang in the girls' ears.

"I'm sorry, maybe I need to talk to Miss Kaslana alone. ”

......

In the silence of the magical enchantment, Dumbledore crossed his fingers and looked at Elena with great seriousness.

"I don't understand, Miss Kaslana. ”

Dumbledore said softly, Elena had never heard Dumbledore speak in such a serious and solemn tone, even when he mortgaged Hogwarts a few months ago, the old man didn't seem to be so angry.

"Maybe the other three ladies didn't know the danger of this beforehand, but I don't think you don't understand what you're doing, and the explosives experiment is no longer a serious thing to fool around. ”

“...... Why?"

Elena looked up, hesitated slightly, and then spread her hands helplessly.

"Actually, it's not the first time I've done the same thing these days, tonight was just an accident, I didn't expect magic to have such a big amplification of conventional chemistry. After all, according to my previous equivalent deduction, ten kilograms of low-purity ammonium nitrate mixture should not have such an effect. ”

"In other words, can I understand that you are making weapons?" Dumbledore's face became more solemn.

"Weapons? Yes, I'm trying to do a weaponizable magical-chemical experiment. ”

To Dumbledore's surprise, Elena didn't mean to quibble, but replied calmly.

"Why?" the old man frowned.

"Because Hogwarts, or the wizarding world, needs weapons. ”

Elena looked directly into Dumbledore's eyes, a dangerous glint on her face, "If you want to intervene in the collapse of the Soviet Union and other major events in the future that are not in the wizarding world, wizards must have a strong and deterrent military base in their hands as a backing. ”

"You mean, power?" Dumbledore replied softly.

An unruly shadow flashed in the old man's mind, the same words he seemed to have heard decades ago.

But then, in addition to the solemnity on Dumbledore's face, he couldn't help but feel a little more confused.

"But...... If it's just for the sake of destructiveness and lethality, magic will have a smarter way. I don't think it's necessary for you to go through such pointless experiments. There is enough war magic that has appeared in this world. ”

"It's not enough – or rather, it's not suitable. Elena shook her head.

"Fire Spell, Mass Phantom Transfer, Transfiguration of War, Avada Curse, Imperius Curse, Plague Potion...... These can indeed exert extremely terrible lethality in war, so that the opponent will die unknowingly. But - they exist like dum bullets and poison gas weapons, with a fatal flaw, a lack of harmless deterrence. ”

Elena paused, glanced at Dumbledore in front of her, and whether he understood or not, thought about it and continued.

"If you know a little about the history of human warfare, as well as the history of the Cold War over the years, it will be clear that the war in the non-magical world ends at nuclear deterrence, and the first premise of the reciprocity of the two worlds is that they need to be afraid of each other. ”

"Magic is far more powerful than you think......"

"Far more mysterious, more incomprehensible, and incomprehensible than I thought. ”

Elena nodded, then added quickly after Dumbledore's words, "But unfortunately, if we want to make the non-wizarding world realize the power of the wizarding world, it seems that we can only achieve this effect through large-scale killings - and if we do, whatever the outcome, it will lead to a never-ending war." ”

Elena has learned a lot about war magic these days.

After all, her follow-up plan involves sucking the bones and marrow from the hairy bear, so it is inevitable that the imaginary enemy will take into account the situation of the Soviet non-magical world, as well as the American non-magical world, that is, a small-scale local war.

Even with the foreknowledge of the history of her past life, Elena must be prepared to have an effective countermeasure in case the worst happens, and she can push the wheel of history back to the greatest extent.

However, according to Grindelwald's introduction, the direction of war in the wizarding world on the mysterious side is too far away, and most of the war magic still focuses on the logic of high mystery and high lethality, which belongs to practical war magic.

"In other words, we don't want to win the war, we want to stop it. ”

Elena cocked her finger and looked at Dumbledore, explaining earnestly.

"It's very unrealistic to get the non-magical world to understand the power of magic in a short period of time, but it's not the same if it's some high-destruction weapons that they can understand some of the principles and destructive power. ”

"The significance of nuclear deterrence is not just about its destructive power. ”

"The most important thing is that it is first and foremost a weapon that can be widely understood and manifested in a simple and crude form - explosion, which is a common method of communication in the entire human world today, just like the sword and armor of the cold weapon era. ”

To use a simple analogy, two people are arguing, one person says I'm going to cut you in two with a forty-meter-long ship knife, and takes out this ship knife and starts peeling potatoes in front of you, while the other person says that if I go down with this sword, your past, future, and present will all be cut off, and then he cuts the air - look, your marriage is now cut off, are you afraid?!

“...... We'll talk about that when Gellert returns. ”

Dumbledore was silent for a moment, then thought for a moment and chose to put the issue aside for a moment.

This is not his area of expertise, and neither opposing nor agreeing with it is a very appropriate choice - as a Headmaster of Hogwarts, he only needs to solve some of the things that are within his purview.

The old man's fingers tapped on the table again, and the magical barrier that surrounded the two of them was silently withdrawn.

"So, why in the History of Magic classroom?"

"It's cold outside the school!"

Elena replied quickly.

Dumbledore: "???"

Glancing at Dumbledore's face, which had instantly darkened again, the girl stuck out her tongue and added.

"And ......"

Today's update~ The weight value of yesterday's chapter has been changed and reduced to ten kilograms.

In fact, the home-made mixed explosives are not as exaggerated as you think, there will be a lot of irrelevant things or internal mixtures that cannot be completely burned to add weight to them, just like ammonium nitrate fertilizer as fertilizer, there will be a lot of other things in it.

According to Fat Chicken's experience as a child, a paint bucket filled with a mixture of home-made ammonium nitrate and nitric acid may not even be able to blow down an improvised dirt barrier if it is not mixed and detonated thoroughly - please do not mix industrial explosives with artisanal explosives.

PS: If you add more~ or the refill will arrive~
