An hour ago.

Snape strode into the Headmaster's office, his face looked tense, but it was easy to see that he was furious at the moment.

"Headmaster! Headmaster Dumbledore!"

Dumbledore looked up from his desk, "Ah, Severus, what can I do for you?"

Snape stood in front of him, he didn't sit down but kicked the chair out of the way, and with only a table between them, he asked angrily, "You recruited Felix Hap as a professor in the school? What were you thinking?"

Dumbledore put down the book he was holding, "Severus, I see no problem with that, Mr. Hap is excellent, and his talents are widely recognized by the wizarding community and, of course, by me."

Snape was rather impatient, "I didn't say he wasn't good enough! I have taught him, I know what he is like."

"Indeed, you once rated him, 'a standard Slytherin' - very high praise." Dumbledore chuckled.

Snape grimaced, "That was not a compliment from me." -- but a taunt.

Dumbledore nodded, "We all know Mr. Hap quite well, and I know what your concerns are, and since he's going to be teaching at Hogwarts, this issue worth a little time, let's sit down and talk about it." He waved his hand and beckoned the chair back.

Snape sat down stiffly, as if underneath his bottom was not a cushion, but a giant fire-breathing dragon.

"Pumpkin juice? Tea? Or a butterbeer?" Dumbledore asked, a cup materialising out of thin air with each word he spoke.

"I don't need any." Snape was very dismissive.

"A cup of tea then, Mr. Hap, very fond of it." Dumbledore placed a cup of tea in front of Snape,

But the way Snape looked, it looked as if he had swallowed a fly.

Dumbledore said gently, "Let's talk. I used to have the same misconceptions about Mr. Hap, but as he grew up, so did my opinion of him in general. It was only recently that I had an in-depth conversation with him and I finally made up my mind to hire him."

"I think you're getting senile." Snape taunted.

"I'm getting older, but over the years, I've become soberer. We're always more likely to make mistakes when we're young, aren't we?"

Snape grunted and then said, "That Felix boy is no good, he's gotten into so much trouble by doing whatever he wants at school because he's strong!"

"Do you know how I got through these years? Because of him, I've met almost half of the purebloods in Britain!"

"I got letters of complaint from them almost every day!"

Dumbledore seemed to laugh a little, but he quickly concealed it with a large gulp of pumpkin juice. He agreed, "True, Mr. Hap was frantic for power in his junior year, but we all know there's a reason for that, don't we?"

Snape pursed his lips and didn't say anything.

He knew, of course, that Felix was in a rough spot, even worse than he had been back then, and at least his enemies were not from his own House.

Dumbledore said calmly, "Minerva once complained to me that the Sorting Hat did not accurately assign students to the right house, and she always thought Mr Hap should be in Gryffindor. What do you think?"

"The boy is a standard Slytherin," Snape said in the same mocking tone as he had back then.

"I agree." Dumbledore nodded, "Mr. Hap ... he is a brilliant wizard, extremely brilliant, one of the most gifted person I have ever met in my life. He was always in search of power, I could see that clearly, even though he rarely showed it after the fifth year, he never stopped chasing it."

"Even after graduation, that was one of my biggest concerns at the time."

Snape listened quietly, he didn't deny Dumbledore's wisdom, the old man's experiences were legendary, and he intended to hear what had made him change his mind in the first place.

"He applied to stay here when he graduated and, frankly, he was more than capable, more than I ever was in spells alone. But I turned him down, not only because he was too young, but also because he had such ambition in his eyes that I was afraid he would go off the track."

"But fortunately he listened to my advice. After his first year of travel, he settled in the Muggle world and began to study them. It was at this time that he and I kept on exchanging letters."

Snape listened quietly, not expecting such an experience between the two of them. You know, when he found out that Felix had become a Muggle researcher, his eyes almost bulged out!

"Maybe he's faking it." Snape jabbed reluctantly.

"No, no, Severus," Dumbledore retorted, "I can still read people's hearts and minds, living a long life has such advantages that I can tell what most people thought even without relying on magic."

"From the time he entered school until now, he has shown no discrimination against Muggles, on the contrary, he has studied the Muggle world very deeply, as this clearly evident through his books. He does not consider wizards superior; on the contrary, he draws a constant stream of wisdom from the Muggle world."

Snape retorted, "I didn't say he discriminated against muggles, Dumbledore! But his ideas are just as dangerous, you know what he states in his book 'How Muggles Think'?"

As if he were reciting a book, he spoke quickly, "Bloodline theory is also prevalent in the Muggle world, but unlike the wizarding world, more and more Muggle nations are abandoning it, thanks to the fact that they are hundreds and/or thousands of times more productive than ever before. The abundance of resources has provided them with a solid foundation to promote education, while the commoners, who are not of good blood, have shown an exaggerated potential to bring the Muggle world up at the speed of a flying broom."

When Dumbledore tried to interrupt, Snape continued, "In the Muggle world, if the proportion of nobles is one, the proportion of commoners is more than ten thousand. And when the rulers liberated the commoners, their efficiency in development overcame all obstacles with unstoppable force!"

The whole headmaster's office fell silent.

Even the portraits listening at the side of the office had their mouths agape. These words did not seem to mention the wizarding world, but simply described and analysed the development process of the Muggle world, but they implied the present-day wizarding world in every way.

One of the portraits shouted in rage, "This is betrayal! A rebellion against the glory of pure blood!"

The other portraits also began to chatter.

Snape glanced at the portrait and said sarcastically, "Headmaster Black, that boy is not a pureblood!"
