The autumn sun shines through the cedar window and falls on Arthur's body, and his deep dark eyes glow with a little starlight.

"Headmaster Dumbledore, you are the most powerful wizard in the wizarding world. If Voldemort had the ability to defeat you, he would have come to Hogwarts by now."

"There is no such thing as a perfect plan in this world, and it's normal for something to happen once in a while."

"You don't need to be frustrated by the failure of your plan to seal Voldemort. You've done a great job."

Arthur thought for a moment, pursed his lips slightly, and then said in a deep voice.

His intuition told him that Dumbledore in front of him was not acting, and the old man in front of him did expose his weakest side to himself at this time.

Quirrell's appearance has proved that Dumbledore's plan to seal Voldemort has failed. But what does that mean? Nothing is indicated.

But as a legendary wizard, Dumbledore actually showed frustration in this matter, which surprised Arthur very much.

Is he really old?

He had the impression that Dumbledore had a strong and strong faith, otherwise he would not have been able to establish the Order of the Phoenix to fight to the end during Voldemort's rise.

"Sure enough... I'm getting old, hehe..."

Dumbledore on the mahogany chair smiled and laughed at himself when he heard this.

In fact, he did have a sense of powerlessness in his heart, and this powerlessness made him feel self-blamed. But not against Voldemort, but Arthur.

He enrolled Arthur at Hogwarts School of Witchcraft and Wizardry, with the intention of protecting Arthur, who had special abilities that were even more powerful than those prophesied.

Can... Less than two months into the school year, Arthur had already been attacked twice, each time under his nose. And every time he was aware of these two crises after Arthur had solved them, Dumbledore felt very guilty in his heart.

"This is something I found in an ancient ruins in the Arabian Peninsula in my early years, a gold coin from the ancient Sumerian kingdom. It's peculiar, and there's some kind of magical power in it. When the owner is in danger, it unleashes a golden barrier to block enemy attacks for about five minutes."

Dumbledore put away his smile, and then touched Fawkes in the nest on the right side of his desk, and after a nod of agreement, Dumbledore reached out and pulled out a simple-looking coin from the nest.

He handed the coin to Arthur and said cautiously.

"Everyone has a secret in their heart... I'm not going to ask what happened last night, but I want to tell you that the more power you have, the more you pay. Arthur, as a last resort... Please try to use your abilities sparingly. Take this..."

"Thank you, Headmaster Dumbledore."

Looking at the gold coin on the table, which looked completely different from the appearance of the gold Galleon, Arthur did not shirk Dumbledore's kindness, and reached out to put it in his pocket.

He was only a first-year wizard student now, and although he had learned most of the spells, he was much worse than an adult wizard in terms of spell mastery and combat experience.

On his first trip to the Forbidden Forest, he was able to take out Gilderoy Lockhart because he activated his writing ability twice, and Gilderoy Lockhart himself was a parallel commodity who could only use the Oblivion Charm.

And in the face of the powerful Quirrell, with his companions becoming his hostages, Arthur can only rely on the power of the audience's sister.

If this Sumerian gold coin really had the magical ability that Dumbledore said, then Arthur would no longer have to seek the help of his sister in the audience when he encountered a powerful enemy in the future, as he did yesterday, and he could have found a way to defeat the enemy in five minutes of injury-free time.

As Dumbledore had said, Arthur didn't want to say how the crisis had been solved last night, and he didn't go any further.

Coming out of the principal's office, the cold and dimly lit corridor made Arthur shiver. With his hands in his pockets, Arthur made his way to the Slytherin lounge.

In the hallway he meets several young wizards, who are chasing Peeves, saying that he should not run away and become his servant...

"If this gold coin can make me study for a week, I can erase 30 million gold Galleons from your bill..."

In the deserted Slytherin common room, Arthur sits by the fireplace and watches A History of Magic. Suddenly, a passage he was reading distorted, and Arthur understood that it was the audience sister communicating with him.

"Is it worth that much?"

Seeing that the audience's sister was willing to erase a 30 million loan for him for this Sumerian gold coin, Arthur was stunned and asked in a low voice.

30 million, that's not a small amount. Arthur was a little moved.

Originally, he only owed 26.04 million gold Galleons to his sister in the audience, but last night, in order to kill Quirrell and change the memories of Harry and others, he was promoted to a billionaire in an instant.

More than 100 million gold Galleons, a figure that is likely to exceed the current savings of the Wizarding Bank's Gringotts UK branch. Even in the Muggle world, that's a whopping £500 million.

For Arthur, who grew up in an orphanage, the amount of foreign debt is equivalent to the number of stars in the starry sky.

"I knew it would take 70 million gold to rewrite the memories of the three Harry, so why didn't I learn the Oblivion Charm in the first place? Turning the three of them into fools is better than owing 70 million gold Galleons!"

The thought of having quadrupled his foreign debt last night made Arthur's heart begin to bleed, and he felt that if he had learned the Forgetting Charm, he would have been able to save this huge foreign debt.

If he was given another chance to choose, he would definitely learn the Oblivion Charm in advance and erase the memories of the three Harry and the others last night.

Even if Dumbledore knew that he had used the Oblivion Charm on the three young wizards and punished him severely, he would not regret it.

But there is no regret medicine in this world, and Arthur can only silently accept this fact.

"You can't use your writing skills like this in the future. Especially if you want something unreasonable to happen..."

Retracting his thoughts, Arthur once again turned his gaze to the book in his hand, and by this time the content of the history of magic on the page had become the reply of the viewer's sister.

"This gold coin is not only a magic prop with special magical powers, but also carries a civilization and records the beginning and end of a civilization..."

Seeing the audience's sister's answer, Arthur suddenly recalled what the audience's sister said, money is not only currency, but also a symbol of civilization.

Thinking of this, Arthur suddenly had an idea, money is just an appearance, and what the audience's sister pays attention to is the civilization of the whole world.

Civilization is the sum total of humanistic spirits, inventions and creations accumulated in human history that are conducive to understanding and adapting to the objective world, conforming to the spiritual pursuit of mankind, and being recognized and accepted by the vast majority of people.
