HP in the name of Slytherin

Severus stood up from the ground, and Catherine stuffed a small piece of cake into Herbo's little mouth, so the little basilisk just lowered its head to eat the snack.

"I didn't want to kidnap you," he frowned slightly, a little embarrassed to say, "The oath just now..."

Catherine touched Herbo's head and looked at him with a very gentle tone, "I think both parties are almost equal and both are satisfied. This is called a contract. Otherwise, one party will take advantage and the other party will be kept in the dark. This is probably called an overlord clause? "

After finishing the snack, the basilisk raised its head like a delicate cat and rubbed the girl's hand. It was long and thin, and it didn't look very lethal.

But Severus now vaguely knew that this was not what Helbo really looked like.

The real thing is thousands of times more terrifying than the ordinary basilisk, and because of his contract with Catherine, he has gained part of the ability to communicate with Haierbo... In other words, if he has the ability, he can fool Haierbo into doing something.

Catherine really gave him "power" as the contract said.

The black-haired little wizard looked solemn. He did not show any expression of ecstasy after receiving such a great gift, but became even calmer.

Catherine smiled and said: "Don't think so much, I gave you Parseltongue mainly for the convenience of contact later."

Severus just looked confused when he saw Catherine touching Halber's head, Halber shook his head, and then a feather fell down.

It's the few feathers on Hai Erbo's head.

[It will probably become three or four inches, otherwise it will not be easy to preserve. 】Catherine said to Haierbo.

Halbo glanced at Severus with disgust, flicked his tail, and the feathers about the size of a fingernail grew larger, almost as big as the palm of his hand. Only then did Severus see clearly that Halbo's feathers were somewhat similar to the tail feathers of a phoenix. However, the color is strangely white, and there is a faint silvery light surging in it. It is very extraordinary at first glance.

"You can wear a rope as a pendant," Catherine handed the feather to Severus, "Speak to it. As long as Herbo is by my side, I can hear it and reply to you."

[You'd better talk to me again when you have something to do and figure out your... Uh huh huh. ] Haierbo's proud and sovereign speech was muffled by Catherine again.

For the sake of "security" and "freedom" in the future, it is indeed better for Severus to stay as he is now. No one knows about his relationship with Catherine, so he can make whatever choices he wants in the future.

But he has clearly sworn allegiance, so...

"I told you not to think so much." Catherine was helpless.

Severus stood there and said stubbornly: "I am not a coward... nor a coward."

Catherine was amused by his serious look, "Then you can't come to my room every night, right? I'm a girl after all?"

Severus' features froze.

Catherine tilted her head and looked at him with a smile: "I think you read books very quickly. Maybe there are some issues you want to discuss with me every day?"

Severus pursed his lips and reached out to take the feather from Catherine's hand.

"You can only activate it with Parseltongue, but if you are in danger or it escapes from you, Haierbo will know it and notify me," Catherine said, "It is also a coordinate for apparation. In the future, you will learn to phantom. By disembodiing, you can use it to move to Haierbo, or I can move to you with Haierbo."

"Can it also be used in Hogwarts?" Severus read in the book and said that there is an anti-Apparition formation in Hogwarts.

"OK."

Severus nodded and put it away cherishedly.

Seeing how understanding he was, Haierbo finally felt a little happy, and went back to eat its cookies and cakes with a groan... Well, he also finished Severus's by the way. After all, we are all together now. , his is Haierbo's.

Catherine came to the bookshelf, took out a book from it, and waved Severus over, "Take this book back and read it first."

The cover has a somewhat dated feel and it says "Psychic and Brain Occlumency".

"The first thing a good wizard should do is to protect your emotions, spirit and brain." Catherine said.

Severus took the book and thanked him softly.

He may know many of Catherine's secrets later on, and if others steal them from him, it will be his fault as a retainer. Contract magic doesn't matter whether he does it intentionally or unintentionally, as long as he leaves here, the contract will judge him as betrayal and cause him to suffer magical backlash.

Catherine said: "In addition to preventing the contract magic from being touched, another reason is that you have probably learned black magic, right?"

Severus nodded, "I've learned some, but I haven't practiced it yet."

At home, he only had his mother's old books, which didn't contain much about dark magic. Severus didn't dare to try it easily. When he came to Hogwarts, he had the opportunity to study it carefully, but the time was relatively short, and the school was very sensitive to dark magic. He could only discuss and study it with people in Slytherin (specifically his two roommates).

"First understand the content of this book thoroughly before studying black magic," Catherine said. "As for modern black magic, I am wondering if it can be improved. If you want to learn, we can discuss this issue together."

"Improved black magic?" Severus' eyes brightened slightly, but he quickly calmed down, "I will understand the contents of this book as soon as possible."

Obviously, there was a big gap between him and Catherine. Since Catherine asked him to read the book first, she must have a purpose.

Catherine explained: "The level of black magic you are learning now is very low, and you have never practiced it, so you can't feel its impact on wizards. When you learn more black magic in the future, if there are no corresponding measures, people's personalities will be affected by magic. That would be a pity.”

Severus almost immediately thought of the basic theory of magic that Professor Flitwick said when he first started school. The accepted logic of modern magic is that emotions trigger magic, and the magic is cast through spells and gestures.

Professor Flitwick only teaches white magic, so of course he talks about positive emotions in class... So what if he switches to black magic?

After contacting Catherine's words, Severus immediately understood the meaning and couldn't help but feel glad that he was not completely immersed in dark magic yet.

He said seriously: "I will study it carefully, thank you."

"Your mind is very clear now, your magic power reserve is probably enough, and your mood and spirit are very stable. The content of this book is just right for you to study." Catherine tapped her chin with her finger and thought for a while, "The Occlumency mentioned in it, you You can learn it, and I sometimes think that if it is expanded, it should also strengthen people’s spirit and emotions, keeping them stable at all times.”

This touched upon Severus's blind spot in knowledge. He hadn't studied the contents of this book yet.

But after all, he likes magic spells. Hearing what Catherine said, he also started to look forward to it: "It sounds like you want to improve Occlumency?"

Catherine smiled gently: "We can discuss it together after you finish studying, don't worry."

"I want to develop an improved version of Occlumency that will give you a lot of points with your professors," Severus said.

"You guessed it," Catherine winked playfully, "So work hard, Severus, or I won't give you extra points."

"You will not be disappointed, Miss Catherine!"

In future celebrity biographies, whenever Severus Slytherin, the legendary Master of Potions and Charms is mentioned, they will inevitably mention that his first improved magic and first created magic were related to him. Advanced Occlumency and Mind Balancing techniques completed together with my wife.

According to insiders, if Mr. Slytherin were to write a personal biography, he would ask the author to order his achievements in chronological order, rather than the more common impact or practicality.

Extra

Achievements sorted by time? Catherine, who was reviewing Severus' manuscript for the first time, smiled meaningfully when she saw the special markings on the author's note.

Next to Tuitui, Severus, who had been immersed in reading since she started reviewing the manuscript, joked: "That's amazing, Mr. Severus, you actually have one more Potions Master title than me~"

The Potions Master, who had been reading the same page for a long time, looked like he was not listening to what was going on outside the window, and asked seriously: "Then I will teach you potions? Or are you telling a bad joke? ... Are you acting coquettishly? [Mrs. Talk about being honest.jpg】"

"I taught you to be frank, so you should use it this way, right?" Catherine was countered by him, her cheeks reddening slightly, "Read your own biography, don't let others write about you."

After saying that, he left the manuscript and went back to the principal's office.

However, the couple’s biographical achievements since then have been sorted by default by time.

Changing the wife's surname from Slytherin is an important setting in the future and cannot be changed. I will say it now (actually there is a foreshadowing of an explanation in this chapter, hahaha)
