Harry, Ron, and Hermione had confused expressions, not knowing what Snape was talking about.

Lupin seemed to be the same, but Evan noticed a slight change in the corner of his eye.

"Severus, do you mean that Harry got it from Mr. Wormtail or one of these people?" Lupin turned and said mildly, "Harry, do you know these people?"

"I don't know!" said Harry.

"See, Severus, it seems to me that this is a product of Jokowi's Magic Joke Shop. Lupin turned to Snape.

"It's us!" Fred and George rushed through the crowd as they explained to Lupin and Snape, "This piece of parchment was bought from Jokowi's Magical Joke Shop a few years ago, and we just gave it to Harry. ”

"Very well, everything is clear!" Professor Lupin said happily, "Harry, they didn't break the school rules, he was just showing his friends this parchment of parchment!"

"Lupin!" Snape said as he took a step forward and lowered his voice, "don't play dumb, you and I both know what this parchment is." ”

"Obviously, as I just said, this is a hoax product, and whoever wants to read it, it insults whomever it wants. Professor Lupin blinked.

"Not this, I've seen it before"

Snape stopped abruptly, looking angrily at an innocent-looking Lupin.

Although he had seen this parchment from his old rival James Potter more than once when he was a student at Hogwarts, he really didn't know what it was or how it was used, and the four of them were very defensive of themselves.

Since Lupin didn't want to say anything, there was no point in continuing the stalemate, and Snape didn't want to discuss his student days in front of the whole school.

"Very well, very well, Lupin!" said Snape, sneering back to his usual very unpleasant tone, "I suddenly remembered that it was a full moon to-night, and I hope you will be alone in the house then, and don't forget to lock the door! ”

Snape looked at Lupin with ill-intentioned eyes, and he deliberately accented the words night, full moon, and locked the door, as if to give everyone some kind of hint.

"No problem, my door is always open for you, Severus!" Professor Lupin said briskly, "and, thank you for the potions. ”

"You're welcome. Snape didn't have a smile on his face, he looked at Lupin, Harry, and Evan viciously, squinted his eyes and continued, "I've made a full pot, if you want it, just let me know." ”

"I started drinking it a week ago, and a little more this afternoon should be enough!" Professor Lupin turned to look at Evan and the others, "Harry, Aven, Ron, Hermione, you come with me, I have something to tell you, about the homework you gave me"

Professor Lupin took two steps forward and seemed to remember something, "Severus, I'll take this away, you don't mind, do you?!"

Snape didn't speak, but judging by his gloomy face, it was clear that he minded.

Lupin pretended not to see Snape's expression, and he quickly stepped forward, picked up the map of the living spot on the table, and stuffed it into his robes.

The four of them followed Professor Lupin closely behind him and left the Great Hall, neither of them daring to glance back at Snape.

It wasn't until the foyer that they dared to speak.

"Professor, we," Harry said quickly, as if he wanted to get the map back from Lupin.

"I don't want to hear an explanation, Harry!" Lupin said in a low voice, looking out at the empty foyer around him, where the other students were still in the auditorium, with no one else but a few of them, "Actually, I just learned that this map was confiscated by Mr. Filch many years ago, and I recognize it. ”

Harry and Hermione looked at him with interest, Ron looked down in thought and didn't know what he was thinking, and Evan covered his forehead weakly.

Professor Lupin didn't just know the map, he was one of the makers of the Living Point map.

Harry's luck was so bad that it didn't work even once he got it, and Professor Lupin found out that he wouldn't give the map to Harry again.

"I don't want to know how you guys got it, I'm surprised you didn't plan to turn it in, especially since Sirius was still lurking around the castle!" Lupin turned his head to look at Hermione, "You did it wrong, Hermione, I thought you would be more sensible than the three of them." ”

"Don't blame Hermione, she just persuaded me to turn this thing in. Harry asked curiously, "Professor, why do you know about this map?"

"That's not something you should know, Harry. Looking at Lupin's appearance, he didn't seem to want to say much on the subject.

"Well, then why would Snape think I got it from the Maker?" Harry continued, not to be outdone.

"That's because," Lupin hesitated, "because the people who made the map probably wanted to lure you out of school, and they thought it would be fun." ”

"Moonface, big feet, pointed forks, and wormtails?" Aven interjected at the right time.

It turned out that after the four of them graduated, the reason why the map would fall into Filch's hands turned out to be this, they deliberately stayed in the school.

From this point of view, James Potter, Sirius Black, Peter Pettigrew, and Professor Lupin must have been as mischievous as Fred and George are now, and they are just as troublesome as Filch is now.

"That's right, it's them. Lupin nodded.

"Professor, do you know them?" asked Harry, a look of urgency.

"We've met before. Lupin replied briefly, looking at Harry more seriously than usual.

"Wait a minute, Professor, about this map. Evan asked in a hurried tone, "Since you know it, you must know how it's made, right?"

"Well, it takes a lot of magical knowledge, not your age."

"Professor, I don't want to know exactly how to make this map. Evan continued, "Just tell me how the four of them, Moonface, Bigfoot, Fork, and Wormtail, came up with the source of the magic to make this map, which in my opinion requires a lot of magic. ”

Professor Lupin looked at Evan in astonishment, and Harry, Ron, and Hermione also looked at him in surprise, wondering why Evan suddenly asked such a question.
