In the next few days, the Knicks focused on Occlumency, not only pulling his sister to work together in the library, but Luna also helped with the reference, and also asked Hermione to study together.

The book is full of spell theory, with not only Lupin's notes next to it, but also Dumbledore's points. Every step, every point, and what to pay attention to are clearly written, for fear that he will not be able to learn it.

Hermione learned on the third day. Tifa and Luna are very fast, and the Knicks have a preliminary grasp of Occlumency with Tifa's help.

On Friday morning, after Muggle Studies class, Nicks was alone in the auditorium writing that he was going to bring his mother to school for Christmas.

Cedric walked over and sat across from him and asked, "I heard Lupin is teaching Harry how to deal with Dementors?" ”

"Yes, I've been, the spell is a bit difficult, you can go to the professor if you want to learn it." Nicks replied as he wrote.

"Not really."

After a while, Cedric found the topic again: "Knicks, Christmas is coming. ”

"Well, I know, don't worry, I'll prepare a gift for you, it won't be the recipe." Nicks said without looking up.

"I'm not rushing you. Recipe what is not in a hurry. ”

Knicks looked up at Cedric, "What do you want to say?" ”

Cedric was a little embarrassed, but asked anyway, "Do you know what broom Harry is going to buy?" ”

"Senior sister asked you to ask?" Nicks joked, "Senior, are you going out of your way like this?" With your performance against Gryffindor, you can still lose to Ravenclaw, won't your players complain? It's not good to sacrifice the interests of the whole Hufflepuff to curry favor with the senpai. ”

"Well, I didn't mean to, it's just, that, lost my mind. And they know it, too. Cedric said.

Nicks asked in a low voice, "What benefits did Senior Sister give you to make you lose your mind?" ”

Cedric's face turned red and he couldn't speak.

"Senior, tell me what it is, and I'll tell you what broom Harry plans to buy."

A female voice came from behind her. "It's nothing, I kissed him at the time, he was afraid that I would fall, so he didn't catch the golden snitch and cheapened me."

The Knicks turned around, and Cho Chang stood behind him, sat down beside him after speaking, and asked, "Can you say what broom Harry bought?" ”

"You've been there? How long have you been eavesdropping? You won't be together, will you? ”

Cedric and Cho Chang didn't answer.

Nix said, "Why do you think Harry is going to buy a broom?" ”

"If you don't buy a new one, do you want to use the Comet series? Then I'm sure I'll win. "Qiu Zhang is confident.

"No comets, but Harry isn't going to buy a broom either."

Qiu Zhang asked anxiously, "Then what is he going to use?" ”

"It's a secret, he doesn't plan to buy a broom anyway, but I answered your question. As a member of Gryffindor, I'm not interested in Quidditch, but I can't divulge secrets, Wood will kill me. ”

Cho Chang was unhappy with the Knicks' answer. "You're quibbling, not answering at all."

Nicks shrugged, saw Dumbledore walking by the door, and said to the two, "I have something to do, we'll talk about it later." ”

swept the things on the table into the small bag and chased after it quickly.

"Headmaster, Headmaster, wait for me."

Dumbledore turned around and asked, "Is there something wrong?" Nick Lestrange. ”

"Headmaster, can I let my mother come to school for Christmas?" The Knicks accompanied Dumbledore up the stairs.

"Theoretically, Muggles can't come to Hogwarts."

"Headmaster, my mother is not a pure Muggle."

Dumbledore froze. "As far as I know, your mother has no magical talents, is not a Squib, and was born into a Muggle family."

"Yes, you're right, but she has an elixir, not a pure Muggle." Nicks quibbled.

Dumbledore shook his head. "Mr. Nick Lestrange, I have to remind you that Muggles who take magic potions are still Muggles and do not become wizards."

"Mr. Headmaster, I think my potions have broken this pattern."

Dumbledore paused. "There is no ordinary person who has done ...... yet"

He halfway thought of Voldemort, his eyes widened, he looked at Nicks and said, "You mean, your potion can turn ordinary people into wizards?" ”

"Yes, Headmaster, but there is a great risk, ordinary people will most likely die if they drink it, and there are very few who can become wizards, and even if they become wizards, they can't cast spells like us, and they can only use a limited number of spells. The good thing is that there is no need for a wand. Knicks explained.

Dumbledore said in an eager tone, "I agree, you can write to your mother." Take care of her, Muggles will have a little trouble walking around Hogwarts. ”

"Okay, thank you, Headmaster." The Knicks waved goodbye to Dumbledore.

He knew why Dumbledore was in such a hurry to leave, he had previously revealed to others that potions could turn Muggles into wizards, but no one cared. Dumbledore knew that Malfoy's family had potion recipes and that Malfoy worked for Voldemort, and he suspected that Voldemort had secretly created a large army.

In the evening, the Knicks come to the Room of Requirement alone, learn Occlumency, and he can turn on the system.

The moment he turned on the system, Nix was filled with madness again, and the only effect of the Occlumency was to make him feel the process of madness eroding the brain.

In fact, it is feasible for Knicks to use Occlumency to stop madness, but there is a premise that what makes him crazy is outside the body.

The system is bound to his soul, and Occlumency is an external defense. Of course, it's not completely useless, at least in the future, others won't hear the babble when they drink the potion. All the madness was left in the Knicks' head.

He forgot his previous plan, and thought about who to drink the potion. Back in the common room, Ron and Hermione are arguing.

"It wants to eat the spots." Ron's voice was sharp.

"The Knicks' cat revolves around him every day, and I haven't seen you like this." Hermione was furious.

"The Knicks are too small to do anything about Spotted. And they've been together for two years and they're friends. Look at your cat, Spotted has been languishing since it came. Ron said.

Nix frowned, how could he say he was small!

"Ron, I have a way to make your rats stronger and live longer."

Ron looked at the Knicks in surprise, the relationship between the two has always been bad, and he rarely takes the initiative to speak. This time, the Knicks took the initiative to talk to him, and he still had to help him treat the spots, which made him feel that the Knicks had a big conspiracy.

"You're going to give Spotted a potion? No, never, I'm not going to let Spotted drink your potion, you're going to poison it. Ron hugged Spotted back. He remembered that when he first met Nix, Nix threatened to kill Spotted, and that incomprehensible words.
