Late at night, Fred and the others had fallen asleep.

Carl sat at the windowsill, the moonlight streaming in through the window, drowning the room in a pale blue silence.

Hogwarts did not fall silent, but had a different kind of daytime bustle.

Sitting high up in the tower, Carl could see a number of silvery-white ghosts shuttling through the clearing.

Hattings squatted on the edge of the bed and jumped to Carl's side, "What's wrong, Carl?" You have a class tomorrow. ”

“·······” Karl gave his guardian a silent look, his hand on his cheek and his head tilted back at the pure moon in the sky. "Hattings, Hattings."

He repeated the name of the black cat, and stopped talking.

"Tonight is a good day, isn't it?" Realizing something, Hattings swept his tail over Carl's arm with a gentle wagg. It also raised its head in Karl's appearance and said gently: "What a beautiful moon! It's perfect for going out for a walk and chatting, isn't it? ”

"Maybe ······" Karl picked up the conversation and fell silent again.

For a long time afterward, they did not make any noise, but quietly admired the vast expanse of the sky and the great moon.

"I seem to understand what Professor Carlo is saying." Carl whispered, depressed.

"What?"

He said that he was fortunate to have a weak personality. Karl said softly.

Hattings screamed, and continued to listen to Carl, it knew its duty, it was the confessed priest, and it was not yet time for it to speak.

"I didn't understand what that meant at first, but Professor Carlo told me to think for myself, saying that it would be good for my future."

Karl reached out and stroked the smooth fur of Hattings, now silent.

"Looks like you've figured it out?" Hattings was very uncomfortable with Carl's sudden performance, and after reluctantly cooperating for a while, he finally couldn't help but speak.

"I live in the East End, which is honestly not a nice place." Carl didn't answer directly, "Ever since I was a child, my parents wanted me to be stronger, otherwise there would always be some bad kids who wanted to bully you." ”

"Weakness cannot be exchanged for sympathy, it can only be exchanged for intensification." "That's something I've learned for a long time. ”

"Is this also your devil's morality?" Carl sighed, "Humans actually have a similar opinion. ”

Karl sighed: "But that's not all, our own weakness is a disaster, but for us, the weakness of others is a good thing." ”

He stroked the fur of Hattings again.

"Weakness means better control, doesn't it?"

Hattings looked back at Carl, his eyes full of concern: "Carl······"

"Weakness, what a great weakness, what a useful weakness."

Carl sighed softly, "So I thought of me. ”

Hattings froze.

"Do you think I have the same weakness?"

Feeling the stiffness of Hattings' body for a moment, and pricking the hair on his hand, Carl withdrew his hand.

"Carl ······" Hastings quickly regained his usual appearance, "Good, you've really grown a bit. ”

"Really?" Carl climbed into bed, suddenly turned his head and said, "Growth? My dad told me that growing up was never like that! ”

"You don't seem to like this kind of growth?" Hattings said.

"Of course I don't like it!" Carr said, "Whether it's Professor Carlo, or Quirrell, God! In retrospect, what exactly was I doing?! I'm learning to be a devil! Even I ······ myself, God! What exactly did I do? ”

"So ······" Hattings' gaze sharpened, "What do you think the world is like?" Hello, I'm hello, everyone's good playhouse? Is it love and peace that build this world? ”

"No, I heard from the pastor in church that the world is full of suffering." Karl said, "But even if a good person struggles in confusion, he will eventually realize a right path." ”

A strange sneer appeared on Hattings' face: "Right way? You're on the right path! Child, it is never a problem to take advantage of other people's weaknesses to achieve their own goals. ”

"Maybe you think that this kind of method is too dirty, and it is not something that kind people will do, but think about it, how many things in this world are done by good people?"

"If everything went according to the rules, you would have died a long time ago! How can we have the opportunity to think about our own means here, and wonder if we have been lured to the depravity!? ”

Carl choked on Hattings' words, and his original anger gradually dissipated.

Hattings sighed, "I thought you had grown up, but you were still a child after all. Just like you learn the dark arts, put your prejudices aside and rethink them. ”

"You have your own purpose, don't you?"

"Yes."

"You're not hurting anyone, are you?"

"This ······ Right. ”

"You did use their weaknesses to your ends." Hattings nodded, and suddenly asked rhetorically, "But is there any other way for you to achieve your goals?" ”

“······ No. Karl thought of this and said angrily, "But Polo promised to teach me!" But I can't even see him now. ”

"You can't expect a salesperson to be so serious about the customer after signing the contract, he is not just your customer." "That's why I have this after-sales service." ”

It coughed: "In short, you see, you have taken advantage of other people's weaknesses in a situation where there is no other way, but that's all, and you have not hurt anyone!" ”

"So, what's not to use in this way?"

On Saturday, Carl found Quirrell in an abandoned classroom.

The desks and chairs in the classroom had been moved aside by Quirrell, leaving only a few dummies.

Quirrell sat in a chair in a pale blue robe, and he hurriedly got up to greet Carl as he entered.

"Carl, you're here." His face was a little pale, as if he hadn't slept well yesterday, and there were a lot of bloodshot eyes.

Carl smiled and nodded, and walked to the middle of the room to stand, "So let's get started, shall we?" ”

Quirrell, who was still thinking about how to say the opening remarks, was slightly stunned, and then quickly nodded: "Okay, okay." ”

Carl and Quirrell learn a lot of things, mainly some spells that can only be exposed to in the upper grades, such as the Iron Armor Charm.

This is one of the few generalized defensive spells in magic, and it is very important in Defence Against the Dark Arts classes, but it is only accessible to students from the sixth grade onwards.

Quirrell's professor was very bookish, and he found a blackboard, as if it were a rehearsal for a future Defense Against the Dark Arts class.

He started with the most basic theories, and made important expositions on the difficult points, and even asked Carl if there was anything he didn't understand.

Of course, Carl has a lot of things he doesn't understand, and the learning of theory is never overnight, let alone something that can be learned by leaps and bounds.

But it's never the same thing to know how to theory and be able to use it.

"Quirrell, I think we can just start learning spells and gestures." Carl smiled at Quirrell and gently prompted, "These theories can be left for future lessons, can't they?" ”
