After hearing Draco's thoughts, everyone couldn't sit still.

"Okay, very good. I was only away for a short while, and you gave me such a great gift!" Professor Snape sat on the comfortable and slightly gorgeous chair in the principal's office, leaning back slightly, holding a cup in his right hand elegantly, which contained his homemade herbal tea.

He sipped slowly, but his eyes were as cold as a knife, as if he could penetrate the heart of everyone in front of him.

Next to Professor Snape, several professors and two parents sat upright, their expressions extremely serious.

The room was filled with a tense and oppressive atmosphere, as if a storm was about to come.

In stark contrast, on the sofa opposite Professor Snape sat a row of children with their heads lowered.

Like a group of frightened little quails, they dared not look up at Professor Snape. They tried hard to reduce their presence, fearing that they would be noticed by the angry Professor Snape.

"Professor, we have made an unbreakable vow..." Hermione bravely raised her hand to speak, then under Snape's expressionless gaze, her voice became lower and lower until she lowered her head again.

Snape put down the teacup with force. The crisp sound of the cup and the saucer made several young wizards tremble subconsciously.

"Yeah, should I also praise you for remembering to make an unbreakable vow?" Snape's ability to be sarcastic became more and more profound.

"No need, Godfather. This is what we should do. Look, this is our experimental record." Every time this happens, there will always be a hero who jumps out to muddy the waters.

Ron and the others looked at Draco with admiration. And you, Draco, are our hero!

Snape was almost laughing with anger, but he really had no way to deal with Draco, let alone lose his temper with Draco.

He glared at Draco, then snatched the notes from his hand and cast a detection spell.

He stared at Filch intently, observing him carefully, as if he wanted to take in every detail of Filch. This gaze made Filch feel uncomfortable all over, and even his scalp began to tingle.

He then circled Filch several times, casting various detection spells.

Not only that, he also asked Filch a series of questions and kept writing, drawing, adding and subtracting in Draco's notebook. During the whole process, his expression was extremely focused, and he seemed to be full of confidence in what he was doing.

"Hmm... the effect is pretty much what I imagined. But, compared to Pu Rongrong..." He muttered to himself, waving the notebook in his hand, motioning Draco to come closer.

Then the two of them came together and started a heated discussion.

Seeing this, Harry and the others gradually relaxed. After all, they had been in such a state of high tension before, which was really unbearable. Now, they could finally breathe a sigh of relief.

Dumbledore looked at Filch kindly, "Argus, now that you have magic, are you still willing to work here?"

"Of course, Headmaster, I have always liked Hogwarts. Besides, I also need to start from scratch. I hope you can give me this opportunity." Filch smiled embarrassedly, his eyes full of longing and expectation for the future.

"Of course no problem. Hogwarts is the best school of magic, and we welcome every wizard who loves learning." Dumbledore's smile deepened and became more sincere.

Even if Filch and the children had made an unbreakable vow, they still felt uneasy. Keeping it under their noses was the best option.

Just now, they arrived at Malfoy Manor. When they learned about the potion newly developed by Snape and Draco, everyone present showed an expression of disbelief, followed by a complex mixture of joy and worry.

The reason for the joy was simple. No wizard could resist the temptation to become more powerful. This potion that could allow people to go further was undoubtedly extremely attractive.

However, they were also worried because it was foreseeable that once this potion came out, it would definitely cause a storm and bloodshed in the entire wizarding world.

At this point, Narcissa bluntly pointed out the biggest problem: "The Ministry of Magic will never sit idly by! If we want to sell this potion openly, they will definitely stop us with all their might." Her words were like a sharp sword, piercing the core of the problem.

Lucius suggested that the young wizards at Hogwarts should first try the potion and he could provide the money for the potion.

"The Malfoys don't need that little money; they only have less than 400 people." These were Lucius's exact words. After all, brothers should settle accounts clearly. This was Snape's invention, so they certainly couldn't use Snape as free labor. The money was what Snape deserved.

I'm talking about you, you shameless old bee!

The effects after use by young wizards may not be obvious - after all, magic is not a substance visible to the naked eye.

Then, we have to wait for those astute parents to notice this change first. Such good news will inevitably lead them to conduct in-depth investigations.

When they discovered that everyone in Hogwarts, from top to bottom, had taken the potion, and that all the young wizards had magical powers that even surpassed some adult wizards, that was the perfect time for them to incite public opinion.

Even the Ministry of Magic would find it difficult to resist the strong public outcry. If it gives in, it could retreat further. In this way, there is hope for the Ministry of Magic to be restructured and reformed.

After learning that the potion had only been tried on Pu Rongrong, they immediately decided to test it themselves to see its effects. Even the serious and rigorous Professor McGonagall was eager to try it.

But before he could react, Dumbledore passively sensed a surge of magical energy in the school he had never seen before. This was the effect of Narcissa's improved magic circle.

Dumbledore told the others in a serious manner, and they nervously followed the guidance of the Phoenix to Filch's room.

Everyone had a strange premonition at the time, and this premonition became even stronger when they saw the increasingly dark face of the Potions Master.

Sure enough, inside he saw a young version of Filch holding an empty potion and a group of young wizards.

"Argus, perhaps you could go ask Madam Pince to borrow some books on basic spells first," Dumbledore suggested tactfully.

Filch hesitated. "I drank the potion on my own initiative. Please don't blame these children. They were just trying to help me fulfill my wish."

The moment he truly possessed magic, he secretly vowed to repay them. He understood Dumbledore's implication, but he didn't want the children to be punished because of him.

"Of course, Argus, don't worry." Dumbledore was a little surprised but also felt it was not unexpected. After all, he was a child taught by Gellert. Dumbledore knew that Harry was studying with Grindelwald.

After Filch left, the first to attack were the deans.

Professor McGonagall severely criticized the children for their recklessness. For such an important matter, they even forgot to cast the soundproofing spell and the confounding spell.

Professor Flitwick looked disapprovingly at the children, all of whom had made a deep impression on him. He agreed with what Professor McGonagall had said: "Think twice before you act, understand?"

Professor Sprout didn't say anything, but worriedly and gently told the children not to be so impulsive.

Several children blushed, except Harry and Draco.

Draco was discussing with Snape, while Harry cast a silencing spell and discussed something with Lucius Narcissa.

Bored - and ignored by everyone - Sirius couldn't help but transform from dog back into human.

I thought I would get the attention of a few children, and then naturally talk about his nephew and godson.

As a result, several people just looked at him in surprise, then looked away with understanding and continued with the previous topic.

The shocked Sirius huddled in the corner like a mushroom.

After finishing the conversation, Narcissa gave Sirius a cold look.

I don't know what's wrong with this stupid dog, he went from one extreme to another.

"Hello, you are all friends of Xiaolong and Harry, right? I am Narcissa Malfoy, and I am very happy to meet you." Narcissa greeted the children gently.

There were a few new faces, probably the friends Harry mentioned in his letter who he had met on the train. Her eyes fell on Hermione without a trace.

"Hello, Aunt Narcissa. Hello, Aunt Cissy." Several people said in unison. They all had a special fondness for this gentle, beautiful, elegant and noble lady.

Draco must be like his mother, gentle and kind. Several people thought.

"I'm sorry, but this isn't our first meeting at Malfoy Manor, so I can't treat you properly." Narcissa took out a few gift boxes. She had already prepared the gifts.

"See if you like it?" She handed out the gifts one by one. "That black dog is an Animagus, and my cousin. Did he scare you?"

Narcissa selectively forgot about the neglected Sirius and was gentle and concerned about Draco and Harry's friends.

"I like it. Thanks, Auntie Xixi~" Inside was a necklace from a brand that Pansy particularly liked. It was super hard to buy from that store!

"I like it too, thank you, Aunt Narcissa." Hermione was a little shy, but couldn't help but feel happy. Inside was the book that she had accidentally complained to Draco and the others about being out of print.

Everyone has received something that they either mentioned casually or something they really liked but were unable to buy for various reasons.

Everyone was very happy, not because of the value of the gifts, but because of the feeling of being taken seriously and valued.

Everyone was having fun, until...
