"You have thought it through very thoroughly. What surprised me most is that you have the patience to revise seven versions." Felix praised.

The twins smiled and said, "It's all because of you. You always give us a lot of revision suggestions, which makes us feel that it is not good enough."

Felix looked at them, "What are you going to do?"

Fred said, "We are currently just promoting it in school, and many people have the intention to buy it."

Felix thought for a while, "The production process is very time-consuming, and your OWLs exams..."

Fred begged for mercy, "Professor, please don't make it difficult for us. We still have enough time now."

George said, "Yes, we have given up the elective courses, and some compulsory courses are completely unnecessary-"

"Astronomy class-"

"History of Magic-"

Felix looked at them with a reproachful look.

"You can't force us. After all, we have not fallen behind in what we should learn. Professor Flitwick even praises us." Fred complained for himself and George.

Felix couldn't do anything about them. Besides, he believed from the bottom of his heart that it was not a good choice to restrict the twins. Providing them with a wider stage and watching them dance, perhaps that is what he should do.

He said thoughtfully: "You should restrain yourself this year. After the exams are over, I mean the OWLs exams are over, I will take you to see something."

Under the stunned gaze of Harry and others, the twins winked at them and walked away.

Before leaving, Fred patted Ron on the shoulder, "Silly Ronnie, you can write it on the parchment: the assessment content is the alchemical item couple mirror, the guide price is three gold galleons, and the price may increase at any time."

Ron turned his head and looked at Harry, "Did you hear it?"

"Of course," Harry was still thinking about the couple mirror. While thinking, he saw the girl who made his heart beat.

Qiu Zhang and her friends appeared. They looked around and saw that there were already seven or eight students sitting in the corner of the venue, holding a magic puppet and recording the magic runes. Her friend

pointed at Cedric's figure and muttered.

Professor Hepp was surrounded by three or five students. He was staring at a cross-shaped amulet and shaking his head. The student next to him looked disappointed.

Qiu Zhang came to Hermione's side, "Hello? We are here to take the test."

Hermione had just finished recording a form, she wiped the sweat from her forehead, "Oh, please wait." She took out a new piece of parchment and said fluently: "Name, grade and college."

"Qiu Zhang, fourth year, Ravenclaw."

"Marietta Edgemore, fourth year, Ravenclaw."

Hermione wrote it down on the parchment, "The content of the test is... Harry?" Harry

came over unconsciously, he stammered: "I came to see, Hermione, see if I can help..."

"I'm fine," Hermione didn't notice his expression, she looked at the two people opposite, they quickly replied: "Thesis, both of us are thesis."

"Put your thesis on the big table, there are clips and quills next to it. The results will be announced in about a week or two."

Harry waited for her to finish, and said to Qiu Zhang and her friend: "I'll take you there."

Qiu Zhang glanced at him and nodded. The three walked away together.

Hermione could faintly hear Harry introducing himself...

Around eleven o'clock, a group of third-year Slytherin students came over - Draco Malfoy, Daphne Greengrass, Pansy Parkinson, Crabbe and Goyle.

Ron walked over excitedly and said provocatively, "I didn't expect you to come, Malfoy. You must be eager to show us the magical ancient magic, right? After all, you are Malfoy!"

Draco looked at him contemptuously, "Weasley, where there is Potter, there is you. Are you his follower?"

Ron showed a surprised expression. He looked at Crabbe and Goyle: "Hey, man, is this how Malfoy sees you? He has no friends?"

Pansy said impatiently, "Hurry up and register us. I'm not interested in listening to your clown speech."

Ron blushed, "Sorry, you may need to write it yourself." He pushed a stack of parchment into Malfoy's arms.

On the other side, Daphne walked to Hermione's side, "Hey, little girl from Gryffindor!"

Hermione glared at her, "Is it you?" Her voice became sharp, and she said aggressively, "I haven't had time to ask you, do you like your magic puppet?"

In the first ancient magic class at the beginning of the school year, the two were fighting for the same magic puppet, and in the end, Hermione was one step faster.

Daphne said proudly, "Sorry, I found a senior sister and exchanged with her."

Hermione was silent for a long time, and suddenly said, "My magic puppet is more powerful!"

"Nonsense!"

"Do you want to try it?"

"Okay, do you think I'm afraid of you!"

...

Felix wiped the sweat from his sweat. He commented on dozens of strange alchemical creations in the morning. Except for a few qualified ones, the others really made him speechless.

For example, a small bottle with a strong pungent smell, the student swore that it contained a magical protective spell that could drive away crazy werewolves.

But Felix confirmed again and again that it was only coated with a layer of pus from the Babo tuber. This thing was still quite dangerous, so he confiscated it directly.

Cedric finally finished his work. Felix looked at his results and couldn't help but admired: "You have mastered fifty-two runes, which is excellent. Did you learn them all by yourself?"

Cedric said: "I asked senior students for advice, and they gave me some pointers."

...

Until two o'clock in the afternoon, Felix watched the last student leave. He said to Harry and Ron: "Thank you for your hard work." The two said goodbye tiredly and left. They needed to go back to sleep.

Hermione, who was an assistant in the magic class, stayed. The two looked at hundreds of papers. Felix sighed and said: "It's a huge workload. I have to work overtime tonight."

"Let's classify these papers first, just like marking the homework of the duel class. I will be responsible for marking and you will be responsible for annotating."

Hermione nodded.

Felix suddenly looked at her, "You seem to be doing well. Have you gotten rid of the trouble of the time converter?"

Hermione said, "I talked to Percy, and he provided a lot of useful suggestions."

She counted on her fingers, "I need to record the time I actually experienced, eat something every four hours, and rest for at least half an hour; there is no need to be so rigid when returning to the past time point, you can advance it a little to leave reaction time; he also recommended me a few abandoned classrooms that he had used before. There are also some unpopular potions of Madam Pomfrey, which can relieve fatigue and improve sleep quality..."

"Sounds good." Felix said.

"Yes, he has been using it for three years and has rich experience. Percy told me that he has been keeping this secret, and even his girlfriend doesn't know."

The two classified the papers according to grade, and then corrected them. For them, the content above was very familiar. The main reference book for the paper was "Ancient Magic Rune Exploration" written by Felix himself. As for other reference books, he has also read them many times.

Hermione was not unfamiliar with it either, because the reference list for the paper was the same one she read last year - Professor Hepp copied the questions that tested her last year.

Felix quickly skipped the familiar content and focused on capturing the shining points of the young wizards' own thinking.

Time passed little by little, and classroom 7 was still as bright as day.

"It's almost time, we will continue tomorrow."

"Professor, I will come tomorrow morning?"

"No, I have something else to do tomorrow morning, and I need to go to St. Mungo's."

"The magic hospital?" Hermione looked at him nervously. The professor was sick? Even Madam Pomfrey couldn't cure him?

"I'm going to visit two friends." Felix said briefly.

Hermione nodded, and she suddenly remembered her earlier question, "Professor, do you know how Sirius Black escaped from Azkaban?"

Felix thought for a while, "I don't know either. He was born in the ancient Black family and was a Death Eater. He may have mastered some very secret magic, and maybe he used it." "

But why did he escape after more than ten years?" Hermione asked puzzledly.

This question made Felix silent: "Yeah, why did he escape after more than ten years? Did he just find an opportunity, or was there a reason why he had to escape from prison?"
