Ron leaned over to look at the parchment and said in surprise, "Why is there my father's name?"

On the parchment, the names of James Potter and Sirius Black occupied the center, and various related characters were introduced from their names, such as James introduced Harry, and from Harry the names of various sources of information were drawn, such as 'Mr. Weasley', 'Minister Fudge', and 'Professor Lupin'.

Harry explained, "Before getting on the train, Mr. Weasley told me to be wary of Sirius and made me swear not to look for him. He must know more."

"Do you want me to write him a letter?" Ron asked tremblingly. To be honest, he was a little afraid.

"I think--"

"Potter! Come here." Professor McGonagall came in from outside and waved to Harry.

The two went to the corner to talk quietly, and Harry's voice became more and more excited.

After a while, he came back, put a peephole on the table with a gloomy expression, picked up a feather pen and added a new name 'Professor McGonagall' on the parchment.

"She knew it, but she treated me like a child."

Hermione looked at the pocket mirror and suddenly said, "This was made by Professor Happ, and Dumbledore commissioned him to complete it. It contains Sirius Black's hair."

She promised Professor Happ that she would not reveal it in advance, but since the mirror had already been delivered to Harry, there was no need to hide it.

Harry was angry and laughed, "So, everyone tried to keep me, the person involved, in the dark?"

"Don't be like that, Harry, they have their reasons. But we can also check those past events ourselves, right?" Hermione said.

Ron's eyes widened, "Do you know what you are talking about, Hermione?"

"This is very important, Ron. We may be able to analyze valuable information from it, such as the magic that Sirius Black is good at. In case we meet him on a narrow road, it is much better than knowing nothing about him." Hermione assigned the task arrogantly: "Ron, you write a letter to your father, and Harry works hard with Professor Lupin."

"What about you?" Ron asked sensitively.

"I'll ask Professor Happ if he knows something, but it's unlikely. Harry's father had already graduated when he entered school." Hermione counted on her fingers and said, "Oh, and Hagrid, do you remember? The night Malfoy was injured, we ran to comfort Hagrid, and he finally drove us out in excitement."

Ron said with approval, "This trick works. Hagrid is a big mouth, he will let it slip."

Harry suddenly reminded the two of them, "Snape must know too. He hates my father, and he also hates Professor Lupin. Maybe..."

"What a good idea, let's go and ask him - Dear Professor Snape, were you beaten up by a man named James Potter when you were in school? We want to learn more about one of his friends..."

Harry was speechless.

Neville walked in with a letter in his hand. He looked around and came to Harry.

"It's a letter from my grandmother, addressed to Professor Happ. I don't know whether to give it to him." Neville's round face showed a hesitant expression.

...

Felix saw the letter the next day. He opened the envelope in front of Neville and took out the letter.

Neville stared at him intently, "What did she say?"

"She asked me to meet at Madam Puddifoot's Tea House this weekend to discuss in detail." Felix smiled.

Neville swallowed his saliva, "Can I, can I follow? This is about me, isn't it?" He reluctantly said the words that Harry and the other two had formulated for him yesterday.

"Oh, no, you are not allowed to enter Hogsmeade yet."

...

"You just agreed? Didn't you fight for it again?" Harry said with his eyes wide open.

"I, I..." Neville stammered, "I think Professor Happ makes sense. I am indeed not allowed to go to Hogsmeade Village."

"You can ask him to take you with you. He is a professor!"

"I didn't think of it at the time..." Neville said, rubbing the back of his head.

Harry was sulking alone.

On the other side, Felix was looking at a glass bottle with interest.

After three days, the eight-eyed giant spider inside was as big as a walnut.

"I know you can understand me, Mr. Acromanthus." Felix said.

"Wizard, what do you want to do?" The Acromanthus said gruffly, its pair of large claws opening and closing continuously, making a "click-click" sound.

"A lot, but I need your cooperation."

"Impossible, wizard, you can't insult me." It said fiercely, waving its large claws angrily.

If it had said this with its original size, it would have been very deterrent.

Felix smiled, "I want to remind you that you attacked me first, and I kept you because you are still useful. If you are useless..."

The Acromanthus tensed up, and it once again remembered the fear of being tortured (shrinking) by this wizard, "So, you will let me go?"

"If you are satisfied, why not? Do you look delicious?"

"Okay, I promise." It quickly changed its words.

"Next, I will use magic to stimulate you little by little, so that you can recover. You have to describe the corresponding feeling. Do you understand?"

"... Understood."

From Felix's perspective, there was a blue magic in the body of the eight-eyed giant spider, which looked extremely orderly, like chains that prevented its body from recovering, but this magic was dissipating at an extremely slow speed.

After all, this magic is a waterless source, and the eight-eyed giant spider itself is a magical creature, with magic in its body, and it is also trying hard to get rid of the confinement on its body.

The later the process is, the faster it is. According to the data obtained in the previous three days, the time is between 5 and 8 days.

'If I can let my magic automatically absorb the free magic, can it exist forever? 'Felix guessed, but this is completely unrealistic, at least he can't even touch a shadow now. Felix

carefully tested it, and the blue magic was very stable, as if it disdained him as the original owner. He did not use the scaling spell to cancel the magic, but instead infiltrated his own magic into the body of the eight-eyed giant spider to help it fight and wear down the blue chains.

Wisps of blue mist appeared from the body of the Acromanthus. Soon, it became the size of a watermelon, but it dared not move at all, allowing Felix to poke and tap it here and there.

Every few minutes, Felix would ask the Acromanthus how it felt.

"What do you feel?"

"Nothing."

After a while -

"What about now?"

"It's like walking into a nest from the sun, and my body feels much better." The Acromanthus likes cold and humid environments.

"It was very uncomfortable before?"

"The transformation process was uncomfortable and very uncomfortable, but after a while, I didn't feel it anymore. I thought I was like this." The Acromanthus said.

Felix looked at it in surprise. Although he knew that the Acromanthus could speak human language, he didn't know that they could express their meaning so clearly.

"Do you usually chat and have tea parties in English?" Felix asked curiously.

"I don't know what you are talking about. Aragog taught us." The Acromanthus said.

Felix understood a little bit. Wild Acromanthus definitely don't have this talent. It's good enough to be able to speak a few short sentences.

But the Forbidden Forest batch is different, their source is Aragog, and Aragog was raised by Hagrid since he was a child.

This gave him some new ideas, maybe he could keep them in captivity?

When he tactfully proposed this suggestion to Hagrid, Hagrid said cheerfully: "That's what Hogwarts does now! I go there every one or two months to see Aragog, he's too old, he may not have much time left. By the way, I extract some of the venom of the eight-eyed giant spider, that's a good thing, part of the school's expenses come from it. But each time Aragog doesn't allow too much to be extracted, he also has to consider hunting for his offspring..."

Felix stared at Hagrid in amazement, this was completely different from what he thought.

Hagrid said happily, "Finally, there is something you don't know, Felix. Most of the intelligent communities in the Forbidden Forest keep in touch with Hogwarts, and Dumbledore asked me to take care of this area."

"For example, unicorns. I usually give them some herbs and supplements. They don't mind me taking some hair. The good things are taken away by Ollivander, and the rest are useless. I use them to make some mats, rags and so on, which are very useful..."

"Or centaurs. They serve as a barrier for the Forbidden Forest, alerting them to the approach of werewolves, trolls and dangerous creatures. They will notify me if they encounter something they can't solve. They are also good at treatment. Their methods are different from those of wizards, but sometimes they can be useful. As for the centaurs' divination, I don't know much about this..."

"The same goes for plants. Professor Sprout sows some seeds in the Forbidden Forest every year."
