Astoria seemed to be understated by the look on her face, but it was clear from her voice that she was concerned about it.

Jon was silent for a moment, then smiled and replied calmly:

"Of course, I've got that memory...... But I suggest you stop the mess and focus your full attention this week. LS exam is better than ......"

Astoria nodded obediently, and after a few moments, she asked softly, "Wait a minute. When the LS exam is over, you're going to take me to see my mother's complete memory, right?"

"That's nature. ”

"Thank you, Jon...... Then I'll go back first, tomorrow is the exam for the Transfiguration class, I think I should go back to the common room and read the Intermediate Transfiguration Guide one last time......"

"It's not advisable to cramm, rest early, don't fall asleep in the exam room tomorrow!"

"Okay!" Astoria smiled sweetly, then turned to leave.

As her figure disappeared from the Headmaster's office, Jon opened a locked drawer on his right, and looked at the silver-white glass bottle inside, slightly stunned.

He smiled helplessly, closed the drawer again, and with a flick of his right hand, the drawer locked itself again.

......

As Astoria left, Jon Hart looked down at several documents...... I signed a few words casually...... Then he asked Fawkes to help him pass on a letter or two......

Just as he was busy, a voice suddenly remembered on the portrait wall: "Someone's visiting, Jon?"

Jon couldn't help but be stunned, who would be looking for him at this time...... Professor McGonagall? But Professor McGonagall is now hosting the old men and women from the Wizarding Examination Board......

"It's Professor Galatia Meleth of Defence Against the Dark Arts!" continued the old headmaster on the portrait.

"Oh!" Jon subconsciously raised his voice and hurriedly said, "Let her in!"

A few minutes later, the "bright" old lady appeared in the principal's office.

"Good evening, Professor Meles!" Headmaster Jon Hart deliberately stood up from his seat and greeted the old professor who had been back at Hogwarts for less than a month, "How have you been at Hogwarts lately?"

"Wonderful!" said the old lady, nodding her head, "both the food and the accommodation are much better than they were more than forty years ago...... If it weren't for this old bone, I would have been overwhelmed, and I'd love to stay here for another year and a half......"

"Hogwarts is a privilege. Jon replied with a smile.

As he spoke, he brewed a cup of black tea, broke it, and handed it to the witch in front of him.

"Oh, you're so polite!" Professor Meles said politely, and at the same time lowered his head and took a sip, and sighed, "Good quality Ceylon black tea...... Thank you so much...... I haven't tasted it in years......"

One old and one young sat down facing the principal's desk.

"Thank you for your contribution to Hogwarts this month...... It's not easy to find a Defence Against the Dark Arts professor who can match you. Jon complimented him as he drank his tea.

Professor Meles is not modest: "To be honest, the quality of education at Hogwarts in recent years has been much worse than in previous years...... At least in the case of Defence Against the Dark Arts, I suspect that forty years ago, 90% of the students in my school would have only been able to pass Acceptable (A) and Poor Dreadful (D). ”

"That's exactly what happened. Jon didn't refute either: "In recent years, the students have to change the Defence Against the Dark Arts teachers once a year, and the level of the teachers is also uneven, so it is naturally difficult for them to learn anything......"

"So, what you asked me about when I first returned to Hogwarts......" Professor Meleth began to mutter, slowly, "I've had a clue lately, too. ”

The incident that Jon asked Professor Meles was, of course-

Forty years ago, when the old professor retired from Hogwarts, Voldemort, who was still young at the time, returned to Hogwarts to apply for the position of "Defence Against the Dark Arts Professor", but was rejected by the headmaster at the time, Albus Dumbledore...... The vengeful Voldemort cursed the position of "Defence Against the Dark Arts Professor", so that every subsequent Defence Against the Dark Arts professor could not work at Hogwarts for a year......

Although he had already guessed the intention of the old lady's sudden visit, Jon still couldn't contain his excitement—

"I'm sorry for your advice......"

......

"I can't talk about pointing. Professor Galatia-Meleth's voice grew serious: "As you mentioned earlier, Headmaster Hart...... I'm the best person to deal with this...... I wonder if you have any research on the magic of curses?"

"I can only say that I understand a little. Jon replied, "Generally speaking, curses need to have a definite object...... For example, to play tricks on your friends, to bewitch your enemies: using hair loss, breaking legs, tying tongues, and many other tricks ......"

"That's right......" Professor Meleth nodded, "That's where the curse of the mystery man is the most bizarre...... Because the goal of 'Hogwarts Defence Against the Dark Arts Professor' is not a clear target...... The mysterious man can't predict who each of the future Defence Against the Dark Arts professors will be......"

Jon didn't speak, just listened quietly there—

"So, he's one of the most gifted students to graduate from Hogwarts......" Professor Meles said thoughtfully, "and I started to fall into the wrong mistakes until I finally changed my mind...... If the mysterious man said that the object of the curse was not the future Defence Against the Dark Arts professor, but ......"

Jon's face changed suddenly, but before he could speak, Professor Meleth had already spoken:

"The object of the mystery man's curse...... Actually, it's me...... Galatia Meles!"

"He cursed you never to retire from your position as a professor of Defence Against the Dark Arts at Hogwarts, did he?" Jon asked calmly, "Because you have not retired from your position, every future professor of Defence Against the Dark Arts at Hogwarts will not be recognized by Hogwarts......"

"That's right, Headmaster Hart...... Your responsiveness is astonishing. Professor Meles agreed, "I'm afraid you've guessed a little bit of information before you asked me to come to Hogwarts again, right?"

"It's just a blind cat touching a dead mouse. Jon smiled and shook his head.

Then, he continued, "So, do you have a solution?"
