Scamander says that the croissant is extinct, but adds that wizards have found it of no value and have studied very little.

Is it possible that the blackfish is not extinct, but has not been discovered by a wizard who knew him for a long time?

After all, the population of this magical world is only a few million, and there are very few people who like to study magical creatures.

Scamander is probably the only one who likes magical creatures and knows about croissants.

In the eyes of wizards, the Clawfish is just a magical creature with no value. But here Arthur is different, it is a potion ingredient worth 50,000 gold Galleons, which can strengthen his body.

He won't give up any possibility of finding a croissant!

Regarding the matter of whether to take out a loan from the audience's sister to exchange for the blood of the black fish, Arthur refuses in his heart.

He can make money now, unlike when he was a child, who couldn't do anything, and had to take out a loan as a last resort in order to continue his life.

Although there is no interest on the loan from the audience's sister, there is no limit to the amount at present. It looks like a pie in the sky.

Some people will take advantage of this once-in-a-lifetime opportunity to endlessly gather wool. Endlessly in debt for their own benefit.

Anyway, there is no repayment deadline, so I'll talk about it first.

Arthur felt that this was wrong, and that it would make you more and more dependent, numb, and arrogant. A little bit of your will will will sink you into the abyss.

Until one day you suddenly find that you have become the most famous, powerful, and wealthy person in the world, but you can't repay a huge loan.

What to do when that time comes?

No one will help you for no reason, and neither is the audience sister.

It lasts for 20 gold galleons a day, and a piece of croissant black fish costs 50,000 gold galleons. The difference in amount between the two is too great.

At noon that day, when Arthur saw his sister in the audience write a copy of 50,000 gold galleons of black fish blood, a possibility sprouted in his mind.

The audience's sister is testing him, whether he is self-reliant, or whether he has always relied on loans.

Although Arthur didn't know what the purpose of the audience's sister was, his inner thoughts were that he didn't want to borrow money all the time.

After spending a few more hours at Newt Scamander's house, Dumbledore returned to Hogwarts Castle with Arthur.

Headmaster Dumbledore, as president of the International Confederation of Wizards, has an important dinner to attend tonight.

After Arthur and Dumbledore separated, they did not go directly back to the dormitory to rest. He first went to the library, and talked for a while with the gentle and kind Mrs. Pince.

He inquired if there was any mention of Brook in the library's collection. One-Eyed Brooke is the author of the ancient book that Newt Scamander gave him.

According to the book, in 667, on an isolated island west of Greenland, he saw a black fish and drew a sketch of it.

Unfortunately, One-Eyed Brook didn't specify the location of the island.

Arthur wanted to know if the medieval adventurer had any descendants today, and if so, he wanted to get more stories of One-Eyed Brook from them.

He hopes to find a glimmer of information about the island from these stories.

"I'm sorry, Arthur. I haven't read any books about Brookless..."

Mrs. Pince's answer made Arthur feel slightly disappointed.

As far as he knew, the books in the Hogwarts School of Witchcraft and Wizardry library, except for a part of the forbidden area, most of the books were read by Mrs. Pinns.

She has a good memory and rarely forgets what she has watched.

Since even she didn't know the person One-Eyed Brooke, it meant that the adventurer was not well-known in his time and was not written down.

Looking for the descendants of One-Eyed Brook to obtain information about the island, this road is temporarily broken.

Arthur comforted himself not to give up. Lady Peaces said goodbye. Head to the castle underneath.

"Arthur, you are

Did you come looking for me?"

Cedric, who had just returned from the secret passage with his two friends, saw Arthur standing alone next to the large wooden barrel at the entrance to the Hufflepuff common room, so he stepped forward and asked with a smile.

"Brother Cedric, long time no see. Why do you smell of alcohol?"

Arthur, who was looking for the entrance to the Hogwarts kitchen, frowned and asked when he saw Cedric's face was slightly red and there was a smell of alcohol on his body.

"Shhhh This can't be nonsense! I didn't!"

As soon as Cedric heard about his drinking, he was directly recognized by Arthur. His face changed, and he retorted nervously.

He is only 14 years old this year, and wizards are not allowed to drink alcohol before the age. If the professors found out, he would have been punished.

「......」

Arthur stared at Cedric in silence with a "do you think I'd believe it" expression.

"It's George and Fred. A prank on both of them! Swap out my non-alcoholic butterbeer for an adult's... I only took a small sip and saw that something was wrong, so I came back. You can't tell the professor about this."

Cedric saw that Arthur didn't want to believe himself, so he had to confess that he was cheated by Wesley.

"Well, then you should go back and get some rest."

A small sip will make the whole body exude the smell of alcohol, Arthur will not be so naïve to believe.

Cedric is in his third year, and according to Hogwarts School of Witchcraft and Wizardry, he is already allowed to visit Hogsmeade Village.

But it's the weekend, and the school rules that students can only go there on certain Saturdays, and they also need a signed permission from their guardians.

Tricking a first-year freshman into not understanding the school rules, Cedric is also bad at learning.

Arthur complained secretly, but he didn't intend to follow up. This is, after all, Cedric's private business.

What adolescent boy has no rebellious period? I don't want to become an adult soon.

Arthur has a clip in his mind of his junior high school days, in which some students in the class learn to wear suits, dye their hair, run to the corner and smoke cigarettes stolen from home in order to pretend to be adults.

"yes, yes! Are you coming for me?"

Seeing that Arthur did not continue to ask, Cedric also breathed a sigh of relief.

"No, I wanted to go into the kitchen, but I forgot the password. I'm here to wait for someone to tell me the password."

Arthur pointed to the huge still life at the end of the corridor in front of them, and said to Cedric.

"It's the first time I've seen a Slytherin student come to the kitchen. Let me think... Today's password is "vanilla pudding."

Hufflepuff students are compared to other three-house students because their common room is adjacent to the kitchen, and there are a number of other reasons. They had the password to enter the kitchen.

"Thank you..."

Cedric's strength seemed to be rising, and his face became more and more ruddy. After giving Arthur the command, he pushed the barrel away and returned to his break room.

Watching Cedric's figure disappear into the hallway of the Hufflepuff common room until the barrel was put back in place, Arthur walked towards the huge still life.

"Mr. Arthur Pendragon of Slytherin... Is there anything you can do in the kitchen?"

Rocky, the house-elf house-elf who was the kitchen caretaker, asked with some trepidation when he saw the Slytherin students coming to the kitchen.

"Don't be afraid, I'm not here to cause trouble. I'd like you to help me see this fish?"
