In the responsive room on the seventh floor, six members of the illegal study group gathered, looking at the words on the small blackboard with serious expressions.

"Tonight we'll talk about—" Roger crossed his hands to his lips: "Lord Savior, Harry Potter's chastity---- dance partner or death. ”

"That's a tricky question," Neville said, embarrassed.

"I'm afraid we can't solve it," said Ginny even more seriously, covering her mouth.

And Harry, the protagonist of this thesis, was made to look sad and angry: "Are you making fun of me!?

"No, think about it another way, Harry. If our discussion comes to fruition, won't you be able to find a dance partner?" This time Hermione uncharacteristically mixed in with Roger's nonsense, and persuaded with a smile on her face.

Since the last conversation, Harry hadn't taken the issue of dance partners seriously, on the contrary, with Roger's encouragement (threat?) he had seriously considered who he wanted to invite...

But with Roger's personal policy towards the little savior under the banner of 'good friends and intimate help', inviting a dance partner has basically become an impossible thing to do...

You must know that this thing is still a powerful insulator of the crowd in Hogwarts, and basically people will avoid him wherever he goes... Hehe, the little savior has no chance to do it at all.

As for Zhang Qiu, the Ravenclaw northeastern girl whom the little savior liked quite much in the original book, Roger didn't see any signs of ill will towards her now. He guessed that maybe Harry had been so passionate about his college life in the past few years that the little savior didn't have much time to think about Flower Girl.

However, it is not ruled out that it is because of his troubles in the past few days, which has caused Harry to completely give up his plan to invite the person he likes...

Therefore, there is this scene in the room where there is a requirement.

"That's the topic, let's start discussing the solution now..."Roger said conclusively, got up and walked to the small blackboard and wrote a few lines: "Then I'll try to come up with some solutions first, and if you have any better suggestions, you can come up with any better suggestions." ”

When he finished writing, the boy turned to face the crowd.

Ginny read out the words on the blackboard with a dull face: "(1). Money can make ghosts grind. (2). Overlord hard bow...... Quite a concise vocabulary..."

Roger tapped his finger at the small blackboard and said solemnly, "These two are the methods that I think are safer and work for Harry..."

"Yes, that's true...... Isn't there such an option as a 'gentleman's invitation to a female companion'?" Harry grumbled.

"Gentleman...?" Roger groaned for a moment, decided to listen to his own opinion, and picked up the chalk and added a clause to the end: (3) Use drugs, hypnosis, etc. to find a prom girl.

"Okay, that's all for now. He tossed the chalk head in his hand.

Harry's head was full of black lines: "Wait...... (3) There seem to be some unnecessary articles in it. ”

"Why... This fits the definition of a gentleman perfectly. Roger glanced back at what he had written.

"But Roger, I don't think it's appropriate to include criminal behavior in the solution," Hermione whispered, tapping her fingers on the table.

Even Luna nodded her head: "Indeed... You're a bit of a violation of ethics~"

"Roger doesn't have that thing, it's a yarn violation!" Harry spat with his arms folded.

But tonight's Roger was quite kind, picking up the eraser and erasing all the three solutions he proposed.

"But then," Ginny said with a serious expression on her idol's business, "Isn't the conclusion of this topic unsolvable tonight?"

"Of course not," Roger Mo said, rubbing his chin and smiling brightly, "I have read a book that says: In the face of a problem that has already occurred, if you can't solve it directly, you can achieve the same goal by solving it in a different way." ”

"For example, when you have a broken bike, if you can't fix it, you can think differently... Do you really have to go by bike?

"I see," Neville said in a sudden realization, "so what you want to say is... Does Harry's dance partner really have to be human..."

After finishing speaking, the little fat man himself felt that something seemed wrong...

"That's right. Roger nodded quite solemnly.

"That's right, you're a ghost, why don't you go to heaven!!" The bruises on the little savior's face have exploded: "You all give me a little bit of moderation!"

"That being said, Harry," Roger said indifferently as the little savior "but it's a perfectly common sense opinion. ”

"What makes sense!?" This time it wasn't just Harry, but even Ginny complained along with him, "Don't look at us as perverted like you!"

"I don't know if you've heard the word 'reading error'?" The corners of Roger's mouth were slightly raised, and he looked at his friends and said slowly: "Forget it, you definitely don't know." ”

Without waiting for these people to ask questions, Roger explained directly, anyway, they must not understand: "It refers to some non-numerical instrumental measurements such as pointers, and the error caused by the instrument's measured value below the minimum scale of the degree,"

"It's like weighing raw materials in a potions class, the minimum scale of a brass scale is 1 ounce (about 28 grams), and if the potion needs to be added for half an ounce, there will inevitably be an error, and the permissible range of this error is 10 percent of the minimum scale..."

This kind of professionalism is a strong word, and a few friends basically didn't understand it, in fact, even if they no longer go to wizarding school, this grade can't be exposed to this kind of knowledge.

"And then, so what?" but not being able to understand didn't prevent Harry from retorting to anything Roger had said, and he asked rather defiantly.

"And then—" Roger smiled strangely, full of indescribable meaning: "It is said that the genetic difference between gorillas and humans is less than one percent..."

"You mean to ask me to invite a gorilla to dance with!?" Harry felt frantic enough to find some weapon and pretend to be careless to get the bad bear's face.

And it's not just him, the rest of them seem to have the urge to give it a try.

Discovering the sudden attitude of his friends, the little savior had a flash of inspiration and calmed down as if he understood something.

He asked in a smug tone that the villain's enemy was about to win, "Speaking of which, Roger, have you noticed that the development of today's meeting seems to have an inexplicable sense of smoothness?"
