"Little ones, although Snape is a difficult man to deal with and often difficult for you, you must also admit that he is a good man. Don't worry, little one, even Snape won't be able to get the Philosopher's Stone. The last level of guarding the Philosopher's Stone was set by me. I can guarantee its security. ”

"Okay, Professor Robin." Listening to Yang Su's words, Harry and the others looked very lost, but they still didn't continue. They know that no matter what they say, they won't believe them.

"By the way, you can try to challenge those tests. Dumbledore said that he seemed to give extra house points to the little ones who passed the test. This is something that even the dean of the academy does not know, and good luck to you. With that, Yang Su led the three of them towards Gryffindor's dormitory. At this time, I happened to meet Professor McGonagall, who had just sent Neville back to his dormitory.

"Robin, are you hurt? Did you catch that unicorn poacher? Looking at the few people in front of her, Professor McGonagall clearly saw that there was an obvious hole in Yang Su's clothes, which was covered with blood.

"I'm sorry, I didn't catch him. But I know who he is. The mysterious man is back. Just in time you're here, I have to go back and rest. You can take these little guys back to the dormitory," Professor McGonagall Yang Su said weakly, looking at the professor in front of him. Although the injury has improved a lot, his body was not very strong due to the dimensional warping device before, and he still looks weak.

"Yes. You have a good rest. Need me to wake up Madam Pomfrey? At this time, it was already midnight and looked at Yang Su's condition, Professor McGonagall asked.

"It's okay, I've already drunk the healing potion. The injury has stabilized and can recover after just a few days of rest. With that, Yang Su walked towards his dormitory.

"Let's go, little ones, I'll take you back to the dormitory." Seeing Yang Su leave, Professor McGonagall took Harry and the others back to the Gryffindor dormitory.

Walking slowly in the corridors of Hogwarts, Yang Su walked quietly. He left Professor McGonagall's line of sight and immediately opened the dimensional portal. Came to Dumbledore.

"Long time no see, Headmaster." Looking at Dumbledore Yang Su, who was sitting in the headmaster's room and sleeping on his stomach, he said loudly, "I have something important to tell you!" Get up!! ”

"Huh~" was woken up by Yang Su's voice, and Dumbledore seemed startled. Looking at Yang Su in front of him, he rubbed his eyes and asked Yang Su, "What happened?" I can let you come to me at this time. ”

Dumbledore wasn't angry, he knew that Yang Su wouldn't wake him up with something meaningless. And Yang Su's next words let him know the seriousness of this matter.

"The mystery man is back."

Dumbledore was, after all, a man who had been through the storm for a long time. He didn't show the same fright as Hagrid and the little one. Instead, he sighed and said meaningfully, "I thought I could only find one of his men." I didn't expect him to be alive. Where did you see him? ”

Yang Su didn't plan to directly say that Professor Quirrell was possessed by Voldemort and let the game end so quickly. He replied to Dumbledore calmly, "In the Forbidden Forest." He is the murderer of the unicorn. I think he'll be back soon to do the tests laid down by our professors. ”

"Are you sure he'll be there in person? From what I know about him, he shouldn't risk his life. Listening to Yang Su's words, Dumbledore asked.

"He should have possessed his servant. It's like a parasite. He wasn't familiar with the body, or I would be dead by now. Saying that, Yang Su pointed to his wound and said, "If it weren't for the luck of bringing the healing potion with him, he wouldn't have come over to check it." I should have hung up by now. ”

"This is the mark left by Avada's life. It seems that this guy is really not good, otherwise you will definitely die this time. Looking at Yang Su's wound, Dumbledore, who was passively turned from a fatal injury to a serious wound by Yang Su, said, "Your luck is really good. Let's go back and rest first, with me in his school, he won't mess around in school. Professor McGonagall also helped me inform the other professors to protect the students. ”

"Well, then I'll go first." Saying that, Yang Su opened the crack again and appeared in his dormitory.

"It's getting more and more interesting, but the school year is coming to an end soon. Soon it's going to be a boring holiday again. I really hope that more students will take my course next year. ”

However, things were not as good as Yang Su thought, and the news of Voldemort's return finally spread among the students. Rumors that Yang Su was injured and dying due to Voldemort's attack spread once again inexplicably.

Yang Su still clearly remembered the appearance of his four students holding flowers to visit him. However, it is obvious that Yang Su's class is once again not many people choose to take it. Many young wizards have asked Professor McGonagall several times to change their elective courses. The reason is to let Yang Su have a good rest.

If it weren't for Yang Su's very, very normal behavior in the next few days, maybe there would still be only those four students next year.

Time flies quickly, and it's almost time for the final exams. Since Yang Su only had four students, he put the assessment of several people together, and did not take the exam by year like other subjects.

"Alright, let's start testing." In the dimensional classroom, Yang Su sat on a chair. Some of the other chairs in the room were also tired. The vacant space left is the examination room.

The four of them stood side by side in a row and spread apart, each with a target in front of them. At this time, Yang Su opened his mouth and said: "Because of your great progress, the difficulty of the final assessment has increased, don't complain that I didn't fulfill my original promise." These exams are simple, and I'm going to let you pass at the very least. ”

"Manipulate the magic to attack the puppet in front of you. and pull the magic to detonate the largest space node next to the puppet. At the same time, the power of the space node after being detonated is condensed and the dimensional stone is condensed. This is a series of operations. As long as the CD is finished, you can get a good evaluation. If the condensed dimensional stone is qualified, it will be evaluated excellently. My annual exam evaluation is very important, and it will determine the level of the Dimensional Magic Book I will give you after you graduate. ”

Hearing Yang Su's words, several people present were very excited. They started their own tests.

As Yang Su's personal disciple, Rien was the first to start. The magic quickly gathered in front of him, forming a ball and following him with a wave of his wand. The magic ball hits the doll. At the same time there was a crunching sound.

At this time, Rien's left hand without holding a wand stretched out and came to Yang Su out of thin air with stones that exuded a mysterious aura.
