As Ivan instructed, he took a quill and parchment and wrote down briefly the things he had learned from Nicol Lemay to make the Philosopher's Stone, and told Althea to mention it to him if she needed money.

At the end of the letter, Ivan hesitated and did not specifically ask Althea to conceal the Philosopher's Stone, but allowed the news to spread in a small area.

After all, owning a magic stone is not an unsightly thing, and with his strength, no one dares to grab it, on the contrary, he can use the elixir of immortality to tempt some people to defect to him.

"When I get back, give this letter to my mother." Ivan folded the parchment and handed it to Dobby, then touched his chin and muttered to himself. "As for Voldemort's infiltration of the Ministry of Magic......"

Ivan closed his eyes and thought for a while, constantly using the Occlumency technique to search for memories, and after about three minutes, he opened his eyes and spoke.

"Let them check the officials of the Ministry of Magic, Yaxley and Auguste, they may have some gains, but tell them not to startle the snake before the official operation begins......"

In the original plane, these two Ministry of Magic officials both defected to Voldemort and became members of the Death Eaters, passing on a lot of key information to Voldemort. In particular, Yaxley even took over the position of Executive Director in the future, and used it as a springboard for Voldemort to take control of the entire Ministry.

Although the current situation is very different from the original plane, and Yaxley and August may not be willing to defect to the Dark Lord anymore, it doesn't hurt to check it out......

"Dobby will tell ......Mrs. Hals word for word," Dobby took the parchment and patted his chest in reassurance, looking at Ivan with adoration in his eyes.

These days, Althea has been overwhelmed by the small actions of the Ministry of Magic, but he didn't want Ivan to come up with a solution easily.

"Is there anything else my mother has told you besides these two things?" Ivan asked.

Dobby shook his head, then nodded again, hesitated for a moment before speaking. "Is it Mr. Doggett who wants me to ask you privately, when can they start moving?"

"What? Can't wait? Ivan raised an eyebrow and put the crown back in his hand in the middle of the drawer.

Of course, he knew why Doggett and the others were in such a hurry, after all, they were already the number one force in the wizarding world on the surface, but they were still suppressed by the Ministry of Magic, and it was inevitable that there was some imbalance in their hearts.

"Sir...... Sir is the greatest wizard and deserves to be the greatest Minister of Magic of all time! Dobby plucked up the courage to speak.

Ivan didn't care about Dobby's boasting, but smiled and waved his hand. "In this way, let Doggett find a suitable location, and I will talk to them in person in half a month......"

Dobby nodded hurriedly, snapped his fingers, and disappeared in place.

Ivan sat alone by the window, sorting through the chaos in his mind, leaving the matter of repairing the Ravenclaw crown behind him for the time being.

There was a Defence Against the Dark Arts class in the afternoon, and Ivan had a hunch that Umbridge would find a way to make things difficult for him, or to keep himself in confinement.

But as it happens, he also has something to ask Umbridge, and it would be best if the other party could provide a quiet and undisturbed place.

……

Just as Ivan thought, after two boring Defence Against the Dark Arts lessons, Umbridge was in trouble without warning.

"Please come to my office after class...... Mr. Hals! ”

"Okay, Professor, I'll look for you after dinner." Ivan took the book on the table and said calmly.

Umbridge was pleased with Ivan's deferential attitude, but for some reason there was a faint uneasiness in his heart. In the past, when she asked people to come to the office, the other party would be a little afraid, but Ivan couldn't see the slightest fluctuation on his face, and the calm was a little scary.

However, Umbridge didn't think much of it, and simply attributed it to the other party's boldness, contempt for authority, and lack of reverence for the professor.

After Umbridge left the classroom, Hermione, Harry, and the others immediately surrounded her.

"Umbridge must know something to ask you about......" Hermione said worriedly.

"yes, are you really going to see the old witch at night? She's not going to let you go easily, or we'd better go find Professor Dumbledore......" Ron suggested.

"Don't be so nervous, maybe Professor Umbridge is just talking to me on a whim." Ivan stood up and spoke.

Hermione glared at Ivan angrily, now was not the time to laugh.

Harry and Ron also felt that Ivan was a little too careless, they had been locked up by Umbridge before, and it was not a good feeling.

Ivan didn't know how to explain it for a while, so he had to talk nonsense casually. "Don't worry, I'm a first-class Merlin Medalist, and I'm also a bit famous in the wizarding world, so Umbridge doesn't dare to do anything to me."

At six o'clock in the afternoon, after dinner, Ivan went to the office of the Defence Against the Dark Arts class under the worried gaze of Harry and others.

There was a knock on the door, and a sweet and greasy voice rang out.

"Come in!"

Ivan pushed the door open and entered, and looked around to the left, and the whole office was decorated by Umbridge like a girl's boudoir, with tables, chairs, and counters covered with lace tablecloths, and many pink decorations and colorful big cat dolls hanging on the walls.

"Sit!" Seeing Ivan come in, Umbridge gestured to the table and chair in front of him.

Ivan didn't shirk either, even when he sat down in his chair.

Umbridge asked with a slight wave of his wand, locking the office door. "Do you know why I called you? Mr. Hals? ”

"Do you have any doubts about the school rules? Need help answering? Professor? Ivan pretended to be puzzled.

The smile on Umbridge's face froze suddenly, and he squinted his eyes and said fiercely. "You should know exactly what I'm talking about, Hals...... Someone reported to me that you had set up an illegal student organization and held a massive rally without permission, is that so? ”

"To be exact, it's just a general study interest group, professor......" Ivan affirmed.

"Interest groups? But I heard that at least 100 people were involved in this illegal assembly! Umbridge stared at Ivan and said word by word. According to the regulations of the Ministry of Magic, student organizations of more than three people, or assemblies, must be reported to me, otherwise the students involved will be expelled......"

"I think you probably don't have a good memory, Professor!" Ivan interrupted Umbridge abruptly. "The Twenty-Fourth Education Order was issued three days ago, and we don't have it when we practice magic......"
