Harry and the others had expected Professor Rochefort to take them back to the Gryffindor common room, but they didn't, and Bernard led them to the Astronomy Tower.

Walking into the alchemy classroom, Bernard did not greet Harry, but first took out his wand and tapped it above the classroom, and then Harry and they saw that the starry sky above the classroom moved, and those star clusters seemed to be moving, and it was only then that Bernard was in the mood to greet the three of them.

"Sit down, Harry, Hermione, and Ron, well, what would you like to drink? Would you like to eat something. Seeing Harry nodding their heads, Bernard snapped his fingers, and "bang" a house-elf in a denim camisole came out of the air, and whispered a few words, and the house-elf disappeared with another pop, and then there were three more milk teas and sandwiches in the air.

"What's wrong with Harry?" Seeing that Harry didn't touch the milk tea and sandwiches, Bernard asked softly.

"Professor, I wonder what it was?" Harry hadn't told his friends what happened to him that day, because what happened that day was a bit too bizarre, but now that he saw this so-called "house elf" again, Harry couldn't help but ask.

"Oh, that's Bell, the house-elf who's been serving our family for a long time." Bernard explained, and asked, "Harry, did the three of you really just happen to get there?" ”

"Yes Professor, I've already said that......" Harry said the same way he had dealt with Dumbledore just now, but alas, Bernard had a big move.

"Harry, don't take out that argument just now, if I hadn't found something, how could I continue to ask you!" Bernard interrupted Harry's words mercilessly, any boy of this age is a bear child, always thinks that he is possessed by a god, with a halo on his head, and can scare the sky and the air, Bernard is the best at curing bear children.

If it weren't for the fact that Bernard thought of the means to get the black diary and didn't know if it would work, why would he go to such great lengths to blow up Harry, it was completely double insurance.

Seeing Bernard's look of affirmation, Harry couldn't help but glance at his friend, and then said very unwillingly: "We did find something, but how would you know, Professor?" ”

"I'm sorting out things for the next group study, and I want to find you an interesting alchemy item for you to come and see." Bernard beckoned the three of them to come around the table, and Harry saw a blank pair of old parchment.

"Mentor, what is this?" Now that Harry himself had admitted that there was a story, Hermione was comfortable communicating with her mentor.

"It's a very interesting thing, and I wonder if it's a reward or a research object for our study group. Look! Bernard explained softly, then drew his wand and pointed at the parchment, and said, "I solemnly swear that I have done nothing good. ”

The old parchment was then unveiled in front of Harry, the dense lines that began to stretch across the parchment centered on Bernard's wand, the thin lines of ink connecting and extending into the shadows, and finally, the front of the parchment read, "Moon Face, Worm Tail, Big Feet, and Pointed Fork Proudly Recommend a Living Point Map to You".

Looking at the surprised expressions of Harry, Ron, and Hermione, Bernard gently tapped his wand to the place where Lady Loris had been attacked before, "Harry, I thought about this map when I was sorting out the special supplies for the study group, and I thought you would like it, but at that time I happened to see a black dot with no name moving on the map, and then I noticed three crazy moving names...... It's the name of the three of you, Harry?! Can you tell us what you found? ”

Harry looked at the map fixedly, then turned to Bernard and said, "Professor, we made Myrtle cry at Nick's death party, so we wanted to apologize to her, and then I heard a voice that seemed to say, 'Smell blood, go kill', and then I couldn't find the voice, and then we saw Lady Loris petrified." ”

Seeing that Bernard didn't say anything, Harry spoke again, but this time asking, "Professor, what's going on with this map?" "You can see that Harry is interested in the map.

"Well, this is a living point map, with four nicknames on it: Moon Face, Worm Tail, Big Foot and Pointed Fork, I originally thought it was a live point map made by them, but after I carefully identified it, I personally think that the age of this map may be older, but some of the traces on it are not the same age, I boldly speculate that this is a map completed by many people, or generations of Hogwarts students, and the four wizards of Moon Face should be the last holders." Bernard thought for a moment and said this, then continued.

"On this map we can see all the passages and rooms that have been recorded and explored, and we can also see the people in these rooms, but just now, very strangely, I only saw a black dot on it and no names, which made me curious." Ron's eyes lit up after Bernard said that.

"Mentor, what's going on?" Hermione asked immediately.

"I don't know, it's just a little speculative." After a pause, Bernard continued: "Names have magical powers, that's for sure, and that's evident from Lord Voldemort. Ron gasped as soon as Bernard said the name, much to Hermione and Harry's dislike.

"Harry, you may not know that the evil wizard you defeated, his name is magical, and any wizard who calls his name Voldemort will be sensed, this is very deep and ancient magic, and only wizards with high mana can perform it."

"On this map of the living point, there is magic associated with the name, so the map can detect the name of the wizard at Hogwarts, this magic mechanism is very old, so far, I don't know how to circumvent it, but like I said, I have some guesses that the magic of the name comes from the wizard's identity, which can be your own or other wizards', so ......" Before Bernard could finish speaking, Hermione continued excitedly.

"So, it's likely that the black dot doesn't have a name, or the concept of a name, or even that it may not be a wizard." Hermione looked at Bernard with excitement on her face.

"I have to say, Hermione, you're so smart, indeed, when we tested this petrified curse before, we found that the magic of this curse is very special, well, very special!" Bernard confirmed Hermione's guess.

"Mentor, do you know what that secret room is?" Hermione seemed to regain her confidence and began to take the initiative, and Harry and they looked at Bernard when they heard Hermione's question.

"Hermione, I'm sorry, I don't know about this, I'm a student of Beauxbatons, I might know a little about the history of Hogwarts, but this kind of mysterious legend is definitely not recorded in the school history, so, I'm sorry." Bernard lied without blushing, but it was clear that the argument was convincing, at least for the three of them.

……

Sending Harry and them to Gryffindor Tower, Bernard smiled and watched Hermione walk in with Leia in her arms, just now, Bernard said that Leia has been in a bad mood recently, and asked Hermione to help take care of her for a while, and Hermione readily agreed. In fact, Leia is not in a bad mood at all, she is completely tired, after all, there have been a lot of things recently.
