An undercurrent is surging in distant Siberia, and in the lively Hogwarts School of Witchcraft and Wizardry, Li Lin is staying in his office in a daze.

His conjecture was right, there were a lot of people who came to proctor today, and the first person sitting at the top was Headmaster Dumbledore. He was accompanied by Professor Felivy, the dean of Ravenclaw College.

"Alright, Mr. Lovegood, it's a little unfair to let you take the exam on a day when everyone is happy, so let's skip those unnecessary procedures and take the written exam first."

Headmaster Dumbledore blinked, and took a piece of parchment.

"There are only two questions, the first question is the magic text of the floating spell, and the second question is the application conditions of the magic text floating charm."

Li Lin nodded and did not speak. Immediately took a quill and began to write, after all, the answer to the first question alone was as long as four or five pages.

Deng Liduo, the parchment that made Li Lin write the answer, was magical, it always had a blank part, and as Li Lin wrote, the parchment became longer and longer, and the front end that had been written was automatically rolled up. After Li Lin finished writing all the answers, he estimated that the length of this parchment should be comparable to his height.

Professor Felivi tapped his wand with a little bit, and the parchment rolled tightly together and flew into his hand. Then he spoke in his peculiar, shrill voice.

"Absi, according to the regulations, the work of marking the papers should be carried out by me."

Dumbledore smiled and nodded, his tall hat swaying with it.

"Of course, my dean."

Then his gaze shifted to Li Lin, though Dumbledore had a smile in his eyes. But Li Lin immediately became nervous.

"Then, Mr. Lovegood, you may cast a levitation charm."

Yes, it's not very demanding, after all, it's very complicated and difficult to achieve such an outdated thing as a magic script.

It's impossible to get at least one pineapple to dance on the table.

Li Lin only needs to let this pineapple fly. He unfolded the magic book, cleared his throat, and began to chant.

Because of the previous practice, the chanting of these magic junctions went very smoothly and was not interrupted, and after all the nodes were chanted, the levitation spell was successfully cast.

However, the result was not so wonderful, not only did the pineapple fly, but also the table where the pineapple was placed floated into the air.

"All right, Mr. Lovegood."

Dumbledore was still smiling, not at all recognizable to his true emotions.

"I think the exam for the magic text is over, you can go back first and wait for the alchemy exam to start in the afternoon. Of course, I'm still invigilating, and if you can't wait, we can finish the alchemy exam right now. ”

Li Lin looked at Professor Felivi, his expression was full of satisfaction and encouragement.

"Okay, Headmaster, I want to take the exam now."

"Oh, what a confident lad."

Dumbledore complimented, pulling out a sheet full of questions for the alchemy exam.

"So, let's answer the question first."

Li Lin picked up the pen and looked at the questions on it, most of the tension in his heart was gone, you know, even Hermione's questions, he passed, so what is the difficulty of these questions that are in the middle of the rules and regulations, like fill-in-the-blank questions?

After answering all the questions quickly, then it's time for the actual operation. Dean Felivier dragged a box of alchemical materials. Put it next to Li Lin's seat.

Dumbledore took off the glasses he was wearing and placed them on Li Lin's desk.

"Mr. Lovegood, I have been following this glasses for many years, and it is a little blurry now, but after using these glasses for so many years, I have developed feelings for it, and I don't want to replace it, can you help me?"

Li Lin knew that this was the exam question. But he was still a little speechless in his heart.

There is no doubt that Dumbledore is cheating, and with the level of healing in the wizarding world, myopia is simply not a problem. At Hermione's first-year level, she was able to straighten her teeth.

And with Dumbledore, with such a powerful magic, is there nothing that can be done about a presbyopia? All he needed was a small transfiguration to get his eyes back to normal.

As for Harry Potter, who also wears glasses, Li Lin doesn't want to comment on the myopia that can be treated in the Muggle world, but in the wizarding world, he has never wanted to treat it, but wears glasses all day long, and he is not a person like Dumbledore who hides many secrets, maybe Dumbledore's glasses have ten or eight protections, or the light of death.

Li Lin was not stingy with his imagination and arranged Deng Liduo in his heart.

However, his hands are not idle. He was checking his glasses on the table, and soon noticed something was wrong.

Li Lin's wandless spell casting level was already extremely superb. The highest level described in the books on wandless spell casting that is published now, that is, Li Lin's, after all, is only wandless casting, not wandless spellcasting. I'm afraid that Merlin is the only one in history who has been able to cast spells without using a spellcasting medium.

However, Li Lin's wandless spell did not work for this glasses, according to the test in the room of requirement, he was able to easily lift 300 kilograms of objects, but a small glasses in front of him could not move.

Rejection of magic? Li Lin thought about it, which also meant that ordinary alchemy methods had no effect on this glasses.

Similarly, because of the conditions set by Dumbledore, it is not feasible to change the lenses.

Li Lin had no choice but to put on white gloves first, and then reached out to pick up his glasses.

The lenses of the eyes are a little unsmooth, and this is the difficulty of the exam. What kind of means should be used to make a pair of glasses that can repel magic by Dumbledore, to restore their original smoothness?

Well, the lenses are removable. The material is a normal material, not a magic item.

Li Lin had an idea, he took out the lava stone from the box, added a few drops of softener, turned the lava stone into a plasticine-like form, printed the lens, and then put the lava stone on the reverse side, wrapping the two lenses tightly.

The next thing that happened was that the natural completion of the face was restored to form and then the heat was generated, and the high temperature caused the surface of the glass lens that Li Lin had dripped with the insulating liquid to begin to melt, apparently destroying the forced spell that Dumbledore might have cast, causing the lens to flow again.

After Li Lin stopped the radiation of Longyan, when he took out the lenses again, the surfaces of the two lenses had become very smooth.

Cool and reattach. After scrubbing with a cleaning cloth, the glasses are as good as new again.

"Alright, Headmaster Dumbledore, I think it can be with you for a long time now."

Li Lin joked.

Dumbledore picked up his glasses, and he wiped the corners of his eyes exaggeratedly.

"Oh, what a miracle, thank you, Mr. Lovegood, for keeping my old fellow company."

Dumbledore stood up.

"I think the two days of exams are over. So, Mr. Lovegood, would you like to have lunch with me? ”

Li Lin hurriedly shook his head, he pointed to the door with an innocent expression, and said.

"I'm so sorry, Headmaster, but I've made an appointment with a friend, though I'd love to."

Yes, Hermione had been following her since Li Lin came to the office in the morning for the exam, and according to Hermione, she would have been waiting at the door.

Dean Felivi smiled, his expression a little subtle.

"It's Miss Granger, she was waiting at the door when I went to get the alchemy materials just now."

"Yes, so, I'm so sorry, Headmaster, Mr. Dean, I need to leave first."

Li Lin bowed, then pushed open the door of his office.

Behind him, the voices of Dumbledore and Professor Feliwick could be heard faintly.

"Hi Hermione."

Li Lin looked out the door, leaning against the wall, facing Hermione, who was flipping through a thick book, the sun shining on her brown fluffy hair, and slightly baby fat face. At this time, she heard Li Lin's voice, and the movement of turning the pages in her hand stopped, and she looked at Li Lin with wide eyes, her eyes full of surprise.

"Hey, Lin, how did you do on the exam?"

Hermione stepped forward, she closed the book, concerned.

"I think it's okay, there's no problem with passing."

Hermione nodded, but with a hint of grumbling.

"How do you just pass? At the very least, it should be O. ”

O stands for the highest score, which is excellent, unless the level of the questioner exceeds the limit of the paper score, and the 100-point exam paper gets 150 points, there will be a better score than this.

Li Lin was a little helpless about this, Hermione was very sensitive to results.

"Well, it's going to be almost a week before I know the results anyway, so don't worry about that for now."

"Yes, you're right, we finally have so much free time, we should go to the library and read a few more books." Hermione nodded approvingly.

Li Lin patted his forehead helplessly.

"Alright, Hermione, let's go have lunch first."

He took the thick book Hermione was holding and went with Hermione to the school cafeteria.

The food in the restaurant is as plentiful as ever, and the house-elves are always efficient and tireless.

Eating the food, Li Lin continued the topic just now.

"Actually, Hermione, I think we should spend the last few days doing some good shopping around Hogwarts, you know there's a lot of places that we haven't been exposed to because of the curriculum."

Hermione thought thoughtfully. Considering that there was too much free time left, she agreed to Li Lin's invitation.

Over the next few days, the two searched for Hogwarts' secret passages, walked on the school's lakeside grass, and watched the stars in the sky at night on the top floor of the castle.

This kind of life is very comfortable, no homework, no thick books. Of course, in stark contrast to the rare laid-back Li Lin and Hermione, Harry Potter and his henchmen were always in a tense state, watching them look startled. Li Lin finally remembered what he had forgotten all along, the Philosopher's Stone.
