I went to Hogwarts after being spotted by Grindelwald

Snape's gloomy face showed no emotion, and he quickly walked to the preparation table.

"According to records, the curse magic of the blood curse will penetrate deep into every drop of blood. I have seen the antidote ingredients for similar curses. The way they solve other curses is to stimulate the magical properties of the medicinal materials to expel the magic of the curse.

, but the way the blood curse magic winds is completely different. If you use this method to prepare the antidote, it can only suppress it for a while, and it will cause great harm to the person who is cursed."

Dumbledore glanced at the pile of medicinal materials with his hands in his hands, and said casually: "Severus, sometimes, being hurt is just a last resort, because there is no better way."

"How do you know there is no better way without trying it? Mr. Headmaster," Snape retorted.

"So we need to try, and we need your help. If there is no other way," Dumbledore sighed, "we can only solve the most urgent tasks first."

Snape paused for a moment and said stiffly: "There will be a better way to solve it."

"This is also my greatest expectation." Dumbledore smiled.

Snape seemed to hope that the antidote would be successful... Sean narrowed his eyes slightly, and he seemed to understand something.

Then, Snape took out several bottles of prepared potions, walked to the glass tube containing Nagini's blood, and motioned to Dumbledore.

Dumbledore took out his wand again, and after Snape slowly poured the potion into the glass tube, he clicked his eyes, and then Sean saw Dumbledore's light blue eyes.

The light shines through.

Is this some kind of magic spell that can see magic changes? Sean craned his neck.

However, the results of the experiment were obviously unsatisfactory. After several bottles of magic potion were dropped, the test tubes either did nothing or boiled violently, and one tube of blood even exploded.

There was no change in the expressions of Dumbledore and Snape. It seemed that they had expected it. After cleaning up, they continued to experiment.

Time passed little by little, and Sean looked at his watch. Several hours had passed, and the progress was not satisfactory.

Dumbledore and Snape continued to discuss during the experiment, and Snape would lean over and write down something on the parchment from time to time. As a 'genius' in Potions Talent 2, Sean said he didn't understand.

I can't understand it either.

Sean, who was a little bored, turned his attention to Nagini. This big snake was locked in a cage. She was obviously still very irritable and bumped against the cage from time to time. However, the cage should be enchanted, Nagini

His movements made no sound.

Sean squatted down and looked at Nagini. She opened her mouth and wanted to bite her, but was blocked by the cage.

Speaking of which, if Nagini changes back to human form, will she still look like she was when she was young?

Just as Sean was thinking about it, Dumbledore's voice rang out, and he exclaimed: "Severus, you are really a genius. In terms of improving and innovating potions, I have never seen anyone better than you."

People."

Sean turned his head, and Dumbledore was holding a tube of blood and looking at it carefully.

Snape was writing furiously on the parchment, not even raising his head when Dumbledore praised him.

"Mr. Principal, this is just the beginning."

"But at least it's a good start. I've seen hope." Dumbledore looked very happy.

After Snape finished writing the last few strokes, he put down his quill and said solemnly: "It seems that the effect is there, but we still have to face a serious problem, dosage."

He looked at Nagini: "There is no problem with a small tube of blood, but if you want to completely remove the blood curse, you need to use a very large dose of potion. The accumulation of other remaining potions will become another highly toxic poison."

.”

Snape's expression turned uglier: "When the time comes, she may return to her human form, but the poison will also take away her life."

Dumbledore raised his chin and said in a deep voice, "Can this formula be improved?"

"Almost impossible," Snape shook his head, "I have been studying for three years..."

He abruptly stopped what he said next, and his expression became increasingly gloomy.

"Now, it can't be improved!" He said angrily, as if he was angry with himself.

Sean blinked, Snape knew.

Dumbledore sighed: "It seems that we still need more attempts."

He turned to look at Sean: "Sean, I'm sorry to have kept you waiting for so long. I thought I could let you take action today, but I was a little too optimistic."

Sean shook his head to show that he didn't care, and then asked doubtfully: "Professor, the purpose of the potion is to get rid of the cursed magic in the blood, right?"

Before Dumbledore could speak, Snape's sarcastic voice rang out: "That's a hundred times more complicated than you think. However, you won't be able to understand it even if you say it, so you can keep your superficial understanding."

Doesn't that mean my understanding is correct? This old bat is so vindictive... Sean sneered.

Dumbledore glanced at Snape and said gently to Sean: "This is indeed the idea, but the magic power of the blood curse is too great. We need too many potions, which will affect the soft and young body.

Cause huge damage.”

Sean heard Snape's breathing quicken.

He touched his nose and said, "Professor, I have an immature idea."

Dumbledore looked very interested: "Of course, tell me Sean, I'm looking forward to it."

"The blood curse is entangled in every drop of blood of the person who is cursed. Can we change our thinking?" Sean pointed at Nagini, "What if we change her blood?"

Dumbledore raised his eyebrows slightly, and Snape snorted.

Sean ignored him and continued.

"In the Muggle world, there is a kind of whole-body blood transfusion surgery. Of course, it is a slow process. The blood curse may contaminate the newly imported healthy blood. So, is there a way, such as draining the blood instantly and still maintaining it?

Her life..."

He spread his hands and said, "We are wizards after all."

Dumbledore began to think, and he whispered: "There are many ways to maintain life, but it is unrealistic to drain the blood completely... Maybe we can leave the minimum amount of blood that keeps her alive, and then use magic potions...

…”

Sean continued: "The magic potion will remove the blood curse and then replace it with healthy blood. That's what I think. But I don't know if it's feasible."

Dumbledore's eyes gradually brightened: "What a wonderful idea... Sean, you gave me another surprise. How did you come up with it?"

Sean smiled back. He was inspired by Riddle's legacy, which included a dark magic called the Blood Drawing Curse...

Thank you, Tom.

Dumbledore looked at Snape: "Severus, Sean's method has a chance, I'm almost sure - I need your help, just replacing blood is not enough, we have to add more

The details are in there.”

Snape's face trembled a little. He looked at Sean and wanted to say something, but in the end he turned away gloomily.

He started to get angry with himself again.
