Being a bastard at Hogwarts is not safe.

"what happened?"

Hermione's voice was sharp and piercing, "Why did the train break down, what happened?"

Harry didn't answer, and several people frowned. This is not the way, Hermione stood up and was going to ask the train driver what happened.

Hermione was very cautious, and carefully opened a gap, for fear that there would be something terrifying outside the door.But her worries didn't bring her good luck, and an endless chill came through the moment the door was opened.

Suddenly, there was a rustling sound, and an inexplicable creature walked in the carriage, approaching them through the corridor.

"What the hell is it!" Harry, Ron, and Hermione all changed their faces.

The footsteps were getting closer, and Professor Lupine finally woke up. A small ball of fire rose from the tip of his wand. The light from the fire illuminated his tired and gray face, but his eyes were alert and cautious.

Through the crack of the door, a humanoid creature in a cloak floated slowly outside.

That's right, floating in mid-air, stretching out a dry hand.

"What is this, he...he came for us, us! What should we do?" Ron was usually good at speaking, but now he was a little articulate.

The few people were extremely frightened, as if they were standing in an extremely cold place, it was bitingly cold, and the moment they entered the door with their hands, they seemed to be facing thousands of crying evil spirits, as if they had entered hell.

The three of them felt cold all over their bodies, and their scalps were a little numb.

"Stay where you are and don't move."

Professor Lupine suddenly reminded him that he was extremely vigilant when he walked to the train door, but to his surprise, that hand retracted. After a while, the lights in the room suddenly turned on, and the floor began to swell again. Shock, the Hogwarts Express is on its way again.

"This is... too scary!" The three were terrified.

"That can't be a person!" Hermione couldn't help but tremble while drinking water, unable to calm down at all.

The gray mouse, Scabbers, suddenly ran back through the crack of the door. Ron was surprised and delighted, and quickly held it in his palm.

"That's right, that's a dementor." Lupine glanced at the mouse in Ron's hand, shook his head thoughtfully and said, "The dementor from Azkaban is probably looking for Sirius Black. .”

Harry couldn't help thinking of the true face he accidentally saw just now, and felt even more uneasy.

"Come on, it's good for you to eat." Lupine handed out chocolates to everyone, while standing up and crumpling up the empty chocolate wrappers and stuffing them into his pockets, "I'm going to talk to the driver, you guys have a good time. Rest, that thing won't come."

He walked past Harry and disappeared into the corridor.

"Did you feel cold when that thing was at the door? It seems that I can't be happy anymore." Ron asked in surprise, his voice low.

"Hearing what you said, I seem to have the same feeling." Hermione was very upset.

"Oh." Harry sighed softly, showing a strange expression.He had an inexplicable illusion that the dementor seemed to be coming towards him, just like Tom Riddle whom he met last year, Quirrell gave him exactly the same feeling before Halloween in the first year, except that he seemed to be beaten by something. Therefore, no judgment can be made.

"I hope Sirius Black will be caught soon!" Hermione said with a long sigh, "Ron, take care of your mouse. If we chased it out just now, we will be in big trouble."

Uncommonly, Ron did not refute, nodded slightly, and found the alchemy cage given by Brian from his bag.

......

"I don't die, you agreed to go dancing with me today, why hide in the room again? Use little Bryan as a shield, don't come out if you have the ability!"

In Nicolas May's hut, Perenelle stood with his hands on his hips in the center of the living room and roared, the sound spread throughout the room, and even Lille in the kitchen trembled.

In the secret room on the first basement floor, hearing Perenelle's loud complaints in the living room, Nicolas could not help raising his hand to his forehead.

This......

Sitting on the rocking chair, he motioned for Brian to sit sideways, and asked, "Brian, you said you have a new idea, come and tell me."

"Teacher, are you really not going to go with Grandma Perenelle? When she comes back later, you may die a miserable death..."

"Ahem... I'm an old man writhing around in the square. Isn't that a joke? No, I won't even go if I'm killed." Nicolas shook his head, as if remembering something, A trace of humiliation appeared on his face, he gritted his teeth and said, "You are disrespectful to the old!"

"Brian." Nicole May leaned forward and said in a low voice, "Let's not talk about that first, let's talk about your thoughts."

Brian laughed and said: "It's just some ideas, whether it can be implemented has not yet been tested. Teacher, this material may be ground into powder with diamonds, which may lead to the weakening of the conductivity of the magic power and fail to achieve the desired effect. If 50g of ruby ​​powder is added If you add 200g of diamond powder and 10g of fire keel and stir evenly, this defect may be covered up, but this amount has not been tested yet, and it is just a conclusion from the last attempt.”

Nicolas nodded, with a pensive expression on his face, and he had some ideas.

In addition, here I think a spirit gathering array should be added, which may automatically absorb the magic elements carried in the air and reduce the user's output. "

Nicolas thought for a while, then nodded slowly.

In the past, I always thought that this student was very talented, but he was always doing crooked ways without doing his job properly. Now he was able to point out some flaws in his design drawings, and suddenly felt that those tricks...

Actually it doesn't make sense.

"In addition, I think the core part may also be slightly modified... Teacher, I really recommend you to use the composite type I designed before... Why don't you hand over this drawing to me to complete, just need Four, no, three materials, I promise to give you a perfect answer!"

Nicole May stroked his beard and sighed: "It really makes sense, I am old, and my thoughts are not as active as your young people..."

Brian raised his eyebrows, he didn't expect Nicolas May to be more foolish than he imagined... persuasion!

Relying on the time magic attached to the system, Brian has quietly seized more than a hundred copies of materials from Nicolas in the past six months, and the market value alone has exceeded tens of millions, not to mention most of them are valuable. no city.

"However...you want to be beautiful, and you want to get rich from me, there is no way." Nicole May glanced at Brian, and said lightly: "This time the materials are different from the past, even I I feel a little distressed, and I still want the middleman to make the difference, do you really think I don't know your damn success rate, little fox?"
