Yang Su was lucky, and after Dumbledore's inquiry, Rian was very excited to become Yang Su's disciple. In addition to the normal compulsory classes, Lien only needs to follow Yang Su to study.

Yang Su also recognized this disciple very much, and he had a strong potential as he was obsessed with dimensional science. Although the control of magic is a little worse, the knowledge of dimensionality is very quickly understood. Although he often encountered problems, each time he was able to verify and solve the puzzle by using transcendent perception to perceive the power of the dimension.

Magic is a move that manipulates the power of the world. The power of elemental magic comes from the elements of the world, and it uses its own magic to communicate with the elements to create attacks. The power of blood magic comes from the life energy of all things, and unlike the elemental mage, the blood mage does not need to communicate energy, he is the controller of life energy himself. The power of dimensional magic is similar to that of elemental mages. Use magic to pull space nodes to create a channel for communication in another dimension to gain power.

And the transcendent perception of these little guys who have seen countless spatial nodes has not yet started. Only the dimensional mage who really links the space nodes to open the passage to another dimension is the real entry.

At this time, what Rien is learning is how to connect the spatial nodes in front of him and open the passage of the dimension to gain power. However, it is not easy to open a passage to another dimension, let alone gain power from another dimension. Even if Yang Su hadn't obtained the full power of Robin Hulos, with his current blood mage's sealed power, there was a high chance that he would be killed by all kinds of beings in the chaotic void of another dimension.

Therefore, whenever Rien tried to open the dimensional passage, Yang Su would appear by Lien's side and watch over him by his side.

While most students at Hogwarts are two or three people in a room, there are always a few exceptions. For example, Ryan lives in a single dormitory, and because of this, it provides a lot of convenience for Ryan to study dimensional magic.

"Still failed," Ryan was using his magic to try to link each of the spatial nodes, but unfortunately there was a slight mistake in the last few steps. The lack of mana control led to the failure of the link-space node this time.

Looking at the clock, he saw that it was very late, and Ryan gave up the idea of doing it again.

"There's still Potions class tomorrow, so let's hurry up and do our homework, or Snape will definitely find a chance to deduct our house's points."

Muttering a complaint about Snape, Ryan stopped his research on dimensionalism and began to write his homework on Potions.

At this time, Yang Su, who was hiding on the side, stopped staying after seeing that Lien had stopped studying dimensionality. After dissipating the doppelganger projected outside Ryan's room, Yang Su walked around the campus.

After teasing the prank-prone Peeves, Yang Su felt a sound. It came from the observatory next to it.

Slowly approaching the place where the sound was heard, Yang Su saw Malfoy. Although he didn't know why he was here, Yang Su knew that his end should be miserable. Because Yang Su saw Professor McGonagall and Filch behind Malfoy.

It looked like he was caught, but he seemed to be trying to justify something. Unmoved, Professor McGonagall and Filch led him to the Slytherin dormitory.

And at this moment, Yang Su heard a slight footstep, which was beside him. But looking around, Yang Su didn't see anyone.

"Delusion, no, there are definitely people." Although for a moment he wanted to think that the idea just now was an illusion, Yang Su quickly reacted. Passing by him were the three Harry cloaks in invisibility cloaks.

After all, it's three people, and wearing the same invisibility cloak is still not enough to completely cover it.

Seeing the three of them fleeing, Yang Su didn't intend to walk over and grab the three of them and hand them over to Professor McGonagall.

"What the hell is going on tonight, why are there students running around at night?" Yang Su, who was strolling around the castle away from Harry and the others, saw a student wandering around in the middle of the night.

"Mr. Longbottom, please explain why I can still see you here at such a late hour? If you don't give a reasonable reason, you won't be able to walk away so easily! ”

Neville Longbottom appeared in front of Yang Su, after all, he was not wearing an invisibility cloak like Harry and the others. Since they all met face-to-face, it would be unreasonable to pretend not to see it.

"Professor Robin, I, I'm out to find Harry. I heard about him fighting Malfoy at noon. I just couldn't find them in the dorm, so I ran out to take them back. ”

Listening to Longbottom's explanation, Yang Su roughly understood why there were so many people running around tonight, but there was one thing that Yang Su couldn't understand, why Malfoy suddenly became so stupid, did he forget that he had cheated Harry like this last time? How did it turn out that he was caught now.

"You're in luck, little one." Yang Su, who was not interested in deducting house points, said after listening to Longbottom's explanation: "Follow me, and by the way, help you find Harry and them." While I'm not going to deduct your house points, you should be prepared to be deducted if you meet Professor McGonagall. I just saw Malfoy being caught by Professor McGonagall and Filch. ”

"Robin, although I don't like to deduct my own house points, but it's a rule. And Longbottom, is what you just said true? "It's fair to say Neville's luck was terrible. As soon as Yang Su's words fell, Professor McGonagall and Filch walked out from the corner next to them.

Fair, who was carrying the lantern, smiled strangely and said, "It seems that I can catch a lot of restless little ones tonight, this year's freshmen are really the most presumptuous I have ever seen." ”

"yes," Professor McGonagall said to Filch's words, "this is really the worst class of students I've ever had." Even George and Fred weren't as presumptuous as a few of them. ”

"Longbottom, as good as you do, you don't have the right to wander around the school in the middle of the night. Gryffindor was deducted fifty points for your actions. Let's hope Harry and the others stay in the dorm room, or each of you will be deducted fifty points. ”

Professor McGonagall was not ashamed of her harshness, and treated the students of her own house even more harshly than the students of other houses. Yang Su remembered that Malfoy just now was only deducted 20 points.

Hearing Professor McGonagall's trial, Neville nearly burst into tears. Having been deducted points so often because of his clumsiness, it was hard for him to imagine how he would face the other students in the academy tomorrow.

"Professor Robin, could you please send him back to his dorm? By the way, Harry and a few of them are not in the dormitory, thank you. I'll keep looking for him in the hallway. ”

Professor McGonagall's voice fell, and Yang Su could only nod in agreement. After returning to the dormitory with Longbottom, Yang Su was helpless to find that Harry and the others did not appear here.

"Where are these three little ones going to go? After that, they should have arrived at the dormitory, right? ”

Not long after Yang Su walked out of Gryffindor's dormitory, he saw Harry and the others who had been caught.

"Tell me why you're here! Harry, I thought you should be very focused on house honors. And Hermione, where is that usually calm and intelligent little girl? And you, Ron! Even George and Fred didn't hang out in the academy in the middle of the night without risking their own safety like you. Not to mention going to a Slytherin fight! ”

"I'm so sorry, Professor McGonagall." Listening to Professor McGonagall's words, the three of them silently bowed their heads in apology.

But seeing that his beloved students were so presumptuous, Professor McGonagall still had no intention of letting them go so simply. From her face, Yang Su could see that she was very angry. "Because you volunteered to fight with Malfoy and wandered around the school in the middle of the night, all three of you were to be locked up, and Gryffindor was deducted 50 points."

"Fifty?!" Harry was overwhelmed - they couldn't hold on to their top spot, a position he had won so hard in the last Quidditch match.

"It's fifty points for each person. Add to that Longbottom, who was just caught, and you were deducted a total of two hundred points for one night, and all four of you will be punished. It's late today, so I'll go back to the dormitory and reflect on it! Saying that, Professor McGonagall looked at Yang Su, who had just approached: "Professor Robin, I'm sorry for you, take the three of them back to the dormitory." I still have a lot of documents to read. ”

"No problem, but you should also take care of your rest. Staying up late is not good for the body. With that, Yang Su led Harry and the others towards Gryffindor's common room.

At this time, Harry and the others hung their heads like defeated roosters. Looking at the remorseful expressions of the three of them, Yang Su asked, "Why do you have to run around at night, I remember that Longbottom said just now that you and Malfoy had a fight." Have you three forgotten the lesson from the last time? But I'm puzzled by how you managed to get Malfoy out of the way. ”

The three of them didn't plan to reveal that they and the others had invisibility cloaks, but they still told the reason for letting Malfoy out.

At noon, the trio had another argument with Malfoy, arguing that Malfoy looked down on Hagrid and thought that Hagrid was not qualified to keep the Norwegian spinosaurus.

As Hagrid's friend Harry, of course, the few of them couldn't bear it, and Ron directly challenged it again. And constantly ridiculed him for his last no-show.

Eventually, the trio came to an agreement, and if Malfoy won and Harry and the others had to take him to the hut in the Forbidden Forest to see the dragon.

Because of the last incident, the three of them also did not intend to keep the agreement. The three of them put on their invisibility cloaks together and quietly lured Filch over to catch Malfoy, who was going to the appointment in the middle of the night.

But the luck of the three men was extremely bad tonight. Not long after escaping Yang Su with the invisibility cloak, the invisibility cloak was hooked by a hook. The invisibility cloak, which could not completely cover the three of them, suddenly revealed a person.

Coincidentally, I met a Peeves who had just been tricked by Yang Su. Caught by Peeves' yelling, Professor McGonagall caught her attention. Next is the scene that Yang Su saw. However, the luck of the three of them was not extremely bad, at least the fact that the three of them had invisibility cloaks was not discovered.

After returning to Gryffindor's dormitory with the three of them, Yang Su left. He knew that the next few days were going to be miserable.

The next day, the Gryffindor students thought something had gone wrong as they passed the huge hourglass that recorded the House Cup score. How could they suddenly be one hundred and fifty points less than yesterday?

Then, the story slowly spread: Harry Potter, the famous Harry Potter, the hero of two Quidditch matches, caused them to lose so many points, and he, along with three other stupid first-graders.

Harry, who had been one of the most popular and admired figures in the school, was now the target of public criticism. Even the Ravenclaw and Hufflepuff students didn't give him a good look, as they had always wanted to see Slytherin lose the House Cup. Everywhere Harry went, people pointed fingers at him, and he didn't keep his voice down when he said insulting things. On the other hand, whenever he walked past the Slytherins, they always applauded, whistled, and cheered. "Thank you, Potter, for doing us a great favor!"

Compared with Harry and others, Malfoy's treatment can be said to be very different. After all, Malfoy had Snape on his head, not to mention that he Gryffindor had lost 200 points in one fell swoop, and the 20 points that Slytherin had been deducted were nothing compared to that.

In this way, Harry and the others spent the next few days under the indifferent gaze of their classmates. At this time, the happiest thing for the four of them is probably that the exam is about to begin. He had to put his head down in revision, which made him forget about his troubles for a while. He, Ron, and Hermione were always alone, reviewing late into the night every day, trying to memorize the intricate potion recipes, the spells and spells, and the dates of major magic inventions and fairy rebellions......

However, it was impossible to get Harry to really be idle. Harry deliberately avoided all sorts of troubles, but in the end he ran into something that was enough to attract attention.

He had just walked out of the library that day, only to hear a sobbing coming from the classroom across the door, and he could hear Professor Quirrell's voice.

He could hear as if someone was threatening him, and it wasn't long before Harry heard Professor Quirrell's compromise. Quirrell then hurried out of the classroom, arranging his scarf as he straightened out. His face was pale, as if he was about to cry, and he strode out of Harry's sight. Harry felt that Quirrell hadn't even noticed him. He waited until Quirrell's footsteps were gone, then he looked into the classroom. It was empty, but the door on the other side had a crack. Harry was about to walk over when he suddenly remembered his promise to himself that he couldn't meddle anymore. However, he was willing to bet on the twelve Philosopher's Stones: it was Snape who had just left the classroom, and from the sound of his footsteps, Snape's steps had suddenly become brisk—it seemed that Quirrell had finally surrendered.
