After coming out of Flivie's office, Felix found an opportunity to be alone with Snape.

"So... Baddy Crouch Jr. was not prepared to secretly poison us and kill us all?" Felix asked. He actually wanted to know what potion Bardy Crouch Jr. made in the secret room.

"Then he must be careful enough to escape hundreds of pairs of eyes in the kitchen." Snape said with his eyes narrowed. "It was a potion for emergency response, which made the dying people survive. I identified the blood of the unicorns and a variety of highly toxic materials, as well as an unknown species of snake venom."

"Sounds like a curse?"

"It's almost the same, the process is extremely painful, but the effect is obvious, right?" Snape said, opening the office door. His office was not changed much, the light was dim, and the shelves against the wall were filled with glass specimen jars.

Felix thought of Voldemort's moans he heard in Crouch's old house and almost understood the statement. He looked around and said dissatisfiedly: "I remember I gave you a magic lamp..."

"A qualified pharmacist will not easily change his life," Snape said calmly, his eyes flashing across the row of large and small jars beside the wall. "And there is a saying that you did not write about the product introduction, the light emitted by the magic lamp has an effect on some dark creatures."

Felix thought about it and it was true. The principle of the magic lamp is to solidify a lighting technique and then slowly release it. The lighting technique has the effect of breaking away the fog and driving away dark creatures.

But this additional effect is not very strong, and it cannot even damage the lowest level Yin corpse.

"Remus has nothing to do with it," Felix said.

Snape said "tsk" and said slowly: "The potion materials are very delicate than werewolf. They need special spells to save to prevent the loss of magic. I remember that I talked about these things in class?"

"A person's energy is limited, and I happen to know you and Belby, so I naturally don't plan to spend too much time on magic potions. For me, it's enough to know some necessary knowledge, such as how to detoxify." Felix said sleekly: "Why don't we talk about ancient magic texts?"

Snape glared at him, "I put the magic lamp in the bedroom."

Felix shrugged, and found half a bucket of gray slime in a suspicious corner of the office, sealed by a transparent lid, he leaned down and looked: "Is this collected from the snail?"

"It has a slight corrosiveness, and I haven't found a good way to eliminate its properties yet," Snape said softly.

Felix blinked, "How about using lighting?"

Snape stared at his eyes and stood there for a long time before he said hard: "It's not that it's not possible... it's worth a try..."

Soon, he took out a few drops of mucus from the bucket. When he lifted the lid, the strong smell of stinky fish and shrimp instantly filled the whole room. Felix immediately put a layer of human-shaped iron armor spell on himself, and he had already used this magic to replace the spell.

"Do you need help?" he asked muffled through the magic, Snape's face was pale, but his fingers were very stable.

"No," Snape squeezed out of his throat, smelling a hint of temperature, his face turned pale, and his throat couldn't stop squirming. He quickly closed the lid and resealed it with magic. Felix cooperated to roll up a whirlwind out of thin air, throwing the turbid air into the corridor of the office.

I hope there will be no little wizard who has just eaten by.

Snape held his breath. He transferred the wet mucus into a small glass bottle and quickly stuffed the plug. After completing all this, he took a deep breath.

On the other side, Felix's palm was already holding a ping-pong ball-sized light ball. Except for a light white halo on the surface, it emitted no light, and looked like a luminous glass ball.

Snape directed the small glass bottle to float over. Felix controlled the light ball to approach at the same time. The light ball was effortlessly drilled into the bottle. Then he quickly cast a spell on the outer wall of the glass bottle, so that the light ball could not overflow.

Losing Felix's constraints, the light ball completely expanded and filled the entire internal space.

"It doesn't seem to work." After a long time, Snape said uncertainly.

"What effect do you want, sizzling sound? That's too rough. The light of the lighting technique is very gentle. Even if it is released against the face, it will at most cause some dizziness and blurry without damaging the eyes." Felix explained.

He had already sat back on the sofa, picked up a book leisurely, and read it casually: "Wait, let the magic work slowly, and sometimes the process of using magic to immerse the material may last for several months."

Snape stared at the small glass bottle in his hand, and after a long time, his eyes suddenly shone with light.

Felix was startled and thought he was going to say something clever and mean, but Snape just couldn't wait to say, "Let's try it a few more times! Use different conditions to compare them."

"Oh..." Felix dragged his long voice, and he didn't want to see that sticky thing anymore. "Wait." He murmured, taking out an Ourobosnake ring from the ring, and under Snape's strange gaze, more than a dozen small balls emitting white light appeared in front of him.

Then, the weifolas ring in his hand suddenly moved, and the little snake's body twisted, swallowing all the light balls one by one, then folded back, hovered in Felix's palm, and turned into a ring again.

He handed the Utrodos Ring to Snape, "It can store ancient magical texts, of course, essentially because its materials can well isolate magic power and greatly reduce the overflow of magic power itself... so it can also be used to store lighting techniques."

Snape took it and looked at it slightly, "Snake monster scales?"

Felix nodded.

...

When Felix returned to the office, Vulcan Valen immediately rushed up, grabbed his clothes and was about to climb up, but its movements came to an abrupt end.

It withdrew its two little hands and gently twitched its nose. The little face immediately wrinkled, and its shiny little eyes were full of accusations.

Felix was stunned for a moment, smelling his clothes, "Does it smell?"

Valen nodded violently and made a retching move.

"Maybe it's the smell of the slime of the larvae of the snail," Felix guessed, "Your nose is so powerful that I'm covering it with a human-shaped iron armor spell, so you can still smell it..."

Valen looked at him proudly.

Felix casts a few new spells on himself, and Valen moves over step by step, tentatively smelling it, and then throws into his arms after confirming that there is no unpleasant smell.

At this time, Felix was holding Valen while thinking that sniffing such a sensitive nose cannot be wasted. Should we add some "extracurricular practice" to normal literacy?

At least it is definitely not harmful to learn to identify the smell of some poisons.

In the evening, Harry came over to learn brain closure.

Taking advantage of the days during the Christmas holiday, Felix explained some techniques of brain closure to him, and Harry was confused and looked confused. Finally, Felix had to let him continue reading the magic book.

Harry comes every two days and sometimes meets Hermione, but in the fourth grade, Hermione doesn't come every week. Her accomplishments in ancient magical literature far surpass others except Felix.

With her current level, even if she no longer makes progress, she is more than enough to be a professor. So Felix is ​​now just assigning tasks and answering questions and answering questions for her assistant from time to time.

Harry turned the book to the fifth page and stared at the portrait of the witch on it with disgust. He was not unfamiliar with this picture. He saw it when he was flipping through materials in the forbidden book area. The witch was originally the cover of a forbidden book. Ron thought he looked very much like Draco Malfoy.

But this time the feeling was completely different. In a trance, Harry found that the witch's face seemed to have become his own, and he was suffering torture on behalf of the witch... This was an illusion. His heavy breathing sprayed on the witch in the book, and then he felt that his skin was hit by a hurricane.

Harry held his breath, his face flushed red. He kept reminding himself that all this was the function of Professor Hayp's magic, and he really had a good idea in this regard...

Harry knew clearly that his body was not injured at all, but his brain was filled with completely opposite emotions.

I can't continue...I have to stop this feeling, otherwise I will definitely go crazy... Let me think about what is the primary method of brain closure, calm down and empty my brain...huh...huh... it's too difficult. Harry felt as if he was thrown into the nest of the snails. The dense snails of snails crawled around him, sparks spraying from his tail, making him itchy and painful...

I want to empty my brain...I want to empty my brain...

But why! Harry thought in annoyedly, a strong anger suddenly surged in his heart. This anger broke through the shackles of magic. He saw clearly that he stood up around him at some point. The magic book fell at his feet, and he was gasping for breath.

Professor Haypu's voice rang in the chair behind the desk:

"If you can make good use of it, anger is also a good way, but it is obvious that anger is not an emotion that can be maintained for a long time, and people are not powder kegs, and it is impossible to lose their temper anytime and anywhere, but... you did a good job, this time you passed the test."

Harry didn't get much comfort from this sentence, and he asked a little depressedly: "Am I bad?"

Felix looked at him with great understanding: "Brain closure is an extremely difficult spell. Many wizards will never get started in their entire lives. The best way to learn is to let your brain experience the feeling of being 'invaded' again and again. Of course, it is difficult to grasp the degree of this, and I happen to have some experience..."

Of course, Harry didn't know that the professor's "experience" refers to invading other people's brains. This experience came from a year when Felix traveled alone. With the help of many dark wizards, he struggled to master the prototype of the magic of the Thinking House.

And now it seems that all efforts are worth it, and this magic has undergone earth-shaking changes.

Harry could only regard Felix's words as true. He sat down and thought about it, and decided to play a card with Valen to relieve his tense mood. However, when he found out that he had lost to Valen, his mood became worse.

This caused him to feel unhappy when he returned to the lounge.

"That book is really that scary?" Ron asked whisper, secretly handing Harry a bottle of butterbeer. "The last time Fred and George went to Hogsmeade's stock, they actually asked me five Sikes!"

"Yes, only three brooms sold for two Sicos." Harry said muffled. He was in poor condition and it was difficult to feel sympathetic to Ron. He took a sip of butterbeer, and the thick foam made him feel energetic and felt that he had come alive from the inside out.

"Tell me about that book, Harry." Ron urged in his eyes.

"Well... you need to face a lot of terrible emotions, and you must try your best to prevent them from affecting you... In short, it's terrible. The professor said that if I could finish it in one breath, it means that my brain closure surgery is introductory, and this is a very amazing achievement." Harry said intermittently, taking the opportunity to drink all the butter beer on his hand.

He looked at the empty bottle with some regret, wondering if he wanted to find Fred and George. If he could drink a bottle of hot butter beer after each practice, it would probably not be so difficult.

"The professor is right," said Hermione, who raised her head from a big book. "I have read its theory. Even those who have mastered brain closure may not necessarily tell how they learned it. They usually learn passively."

"Passive learning?" Ron looked at her in confusion.

"Invaded." Harry said, relaying what the professor said to him to Ron. "The best way to learn is to let your brain feel the feeling of being invaded again and again." He thought for a while and added: "I guess it's to make the brain sharp enough."

Ron's enthusiasm obviously subsided.

"Do you want to learn this?" Harry asked, not understanding this idea very much. Ron laughed dryly and said stammeringly: "Didn't this magic be difficult? I thought, if I learn it..."

"It will be very respectful to say it." Hermione helped him add the unfinished meaning in his words.

"Actually, there is a simple way. The professor mentioned to me... Do you remember my dementor doll? The professor said that the thing is equivalent to a simple magic book. If you want to try it, I can lend it to you." Harry suggested, the thing was locked under the box by him.

Ron was quite moved, but after thinking for a long time, he gave up. He lay on the table and muttered: "I'd better study the magic that I need to use for the second project. Do you think I should learn the head spell or the drain spell first?"

"The bubbly curse is the content of senior grades." Hermione reminded him.

"But the human-shaped iron armor curse is not easy. I haven't even reached the entry conditions." Ron groaned, "I think I'll be drowned, Harry, I'll be the first warrior to be eliminated."

"Don't think so," Fred's voice suddenly appeared, and he sat next to Ron, and he said with a smile: "Think about it, maybe Ifamoni is at the bottom again this time."

"I suggest you better practice swimming, otherwise it will be embarrassing to have no strength halfway through the swim." George grinned.

"You reminded me," said Hermione, "I'm only concerned with the magic part." She took out a small notebook from her schoolbag and recorded George's words. Harry knew that it was Hermione's plan to deal with the second project. So far, half of it had been written, and he and Ron had no courage to read what they had written on it.

At this moment, Ron suddenly raised his head, as if he had thought of something, and stared at Fred and George blankly.

"You can curse yourself?" Ron asked bluntly.

"Oh...of course, this is a magic that must be mastered by pranks. We suffered some losses in the past..." Fred said with emotion.

"Teach me," Ron said.

"What?" Fred and George looked at each other.

"Teach me the spell." Ron repeated.
