"Kreacher... Then I should know what's going on. Thank you for your help, this news is very useful for me."

After hearing that Kreacher knew the whereabouts of the Sheep's Horn Blackfish. Arthur's mind suddenly remembered the isolated cave where Voldemort's Horcruxes were hidden.

There was a black lake in the middle of that cave. There is a small island in the lake, and in a stone basin above it is the Horcrux of Voldemort (fake).

The top of the Black Lagoon was set up by Voldemort with a lot of magic, and wizards could not use magic to reach the island. The Black Lagoon was also kept by Voldemort in captivity to prevent someone from swimming to the island and stealing his Horcruxes.

These walking corpses are covered in carrion, which is one of the favorite foods of the croissant black fish.

"Kreacher can spot the croissant blackfish. I guess it was discovered when Regulus's body was dragged into the Black Lake by the walking corpse after he took Regulus Brick to steal the Horcrux Changer."

Arthur secretly thought in his heart that the news that Rocky brought to him could be said to be the happiest thing he had ever encountered today.

However, at present, it is still very difficult to go to that kind of isolated island to catch sheep's horn black fish.

At present, the only people who can go to the isolated island are Voldemort and the house-elf Kreacher.

Voldemort... Don't think about it. And the house-elf Kreacher is also a very stubborn guy, and it is very troublesome to ask him to take Arthur to the isolated island.

"Looks like we're going to need to get help from someone else..."

Suddenly, a very reliable person appeared in Arthur's mind.

After saying goodbye to the house-elf Rocky. Arthur and Hermione followed the same path back to the hall of the magic staircase.

At this time, Hermione only cared about the package in her arms, thinking that Arthur must not find out that the contents of the package were his new book.

To ease the atmosphere of silence. As well as distracting Arthur, Hermione spoke suddenly.

"What kind of magical creature is the croissant? Arthur, what are you doing with it?"

"It's a magical creature that wizards think is extinct. I came looking for it mainly to study it comprehensively and add some material for the future."

"Materials? You're going to start writing again?" Hermione couldn't help but exclaim when she heard Arthur prepare the materials.

In the two months since he published Harry Potter and the Philosopher's Stone, he has published three more books. Isn't he tired? Haven't run out of inspiration in your brain?

Hermione couldn't help but glance at Arthur with the look of a monster.

"Write when you have time, anyway, there is nothing else to do, it is better to write to make money." Okay, the magic staircase leading upstairs is coming, you go up."

The feeling of being in huge debt, how could a little girl understand, Arthur didn't want to explain anything, seeing the magic staircase leading to the seventh floor of Gryffindor slowly coming this way, it was time to part with Hermione.

"Thank you, Arthur. If it weren't for you, my package would never have been found."

Hearing that Arthur's purpose was to make money, Hermione suddenly remembered that Arthur was an orphan, and for a moment empathy came to her heart, and she began to reflect on whether she had been too unfriendly to Arthur before.

"You helped me first, goodbye!"

Arthur waved his hand, ready to wait for the magic staircase to reach the second basement level. He didn't have classes this afternoon, so he was going back to his dorm room to rest for a while before going to the library to write.

Hermione waved goodbye to Arthur and ran up the magic staircase with her package in her hands. But then the accident happened suddenly, and Peeves, Hogwarts' favorite mischievous ghost, suddenly burst out of one side of the wall and ran in front of Hermione to make a grimace.

Hermione, who was thinking about something, was defenseless for a moment, and was startled by the sudden appearance of Peeves.

She exclaimed, and her hands subconsciously let go of the package.

By the time she realized it was too late, the package had slid down her wizarding robes and rolled down the stairs to Arthur.

"Oops!"

Hermione saw that the Blotte marker on the package was pointing up, and Arthur was looking down at the package.

"The mark of the Blotted Bookstore. Is it mine inside? I didn't expect Hermione to be a fan of my books as well. Do you need me to sign it for you?"

Arthur picked up the package, realizing that it weighed exactly the weight of his three new books, and asked Hermione, who was standing at the edge of the magic staircase.

"Ah! I'm not a fan of your books! I bought it for someone else!"

Hermione blushed and snorted. Arthur snatched the package from his hand and ran towards the Gryffindor entrance above the stairs without looking back, the portrait of the Fat Lady.

"No, who wants your autograph? What a self-righteous guy."

The last thing you want to happen, it happens. This made Hermione very embarrassed. Like a little girl whose first love letter was discovered by her parents, she shyly ran into the Gryffindor common room.

"I made a mistake, I was made a little too much by the book fans at noon. Not all book lovers like the author's... How did I forget about such a thing?"

Arthur scratched his head and said in distress. But he found another reader, which made him very happy.

As long as there is one more reader, it means that he has one more money, and he can exchange one more loan.

......

Time flew by, and a week later, at nine o'clock in the evening, Arthur and Draco said goodbye to Pansy and emerged from the Slytherin common room and walked towards a classroom on the first floor.

When they arrived in the classroom, Professor McGonagall was already standing on the podium, staring at them with a blank face.

Glancing around the classroom, Arthur saw that Harry and Hermione were already sitting in the first row of chairs, their heads bowed in a proper manner, and they didn't know if they were really studying hard or if they were afraid of Professor McGonagall...

"Mr. Potter, Mr. Pendragon, and Mr. Malfoy, you've already been punished by the school once, why don't you learn your lesson? Do you know ......?"

When Arthur and Draco sat down at the gesture of her eyes, Professor McGonagall sighed and pointed out with a serious expression.

"And Miss Granger, you're the professor's favorite student. I've always thought you were the least likely person to break the school rules, so why didn't you cast a spell on Mr. Malfoy without first knowing the truth of the matter?"

After Professor McGonagall reprimanded the three of Arthur, she turned her eyes to Hermione's body, wanting to criticize Hermione for once, but seeing that her tears were about to flow out, she had no choice but to give up.

Professor McGonagall took a deep breath and shifted her gaze to Arthur, the only one looking up at her.

"Arthur, you are the fastest and most gifted student to learn Transfiguration in all my years as a Transfiguration Professor. I've just taught you how to transform into elementary items, and you can use the Living Transfiguration Charm. But you can't be complacent and have the courage to use Transfiguration Charms on your seniors. They're bullying you, you can report it to Professor Snape......

That afternoon, Professor McGonagall heard from Filch that Arthur had turned three Slytherin seniors into rats and threw them into the toilet paper basket.

The anger is that Arthur once again violated the school rules, and the joy is that Arthur actually learned to transform into a living body.

Seeing Arthur's expressionless face, Professor McGonagall angrily told the other three about their violations of the school rules.

Hermione uses a spell on Draco during flight lessons, and Draco fights Harry during flight lessons......

"Remember! If you continue to violate the school rules, you won't simply go to patrol the Forbidden Forest!"

Professor McGonagall had forgotten the last time she had been so angry, and only after feeling a little dry mouth did she end the reprimand and explain the punishment.

"What? I want to go to the Forbidden Forest???

When Harry and Draco heard that this punishment was still patrolling the Forbidden Forest, an ominous premonition haunted their hearts, and their faces turned pale in an instant, and they couldn't help but exclaim.
