"Well, Harry, if you are absent-minded, you'll be here this year." I said to Harry in the secret room where the basil monster used to live.

"Sorry, I..." Harry put down his wand with a little embarrassed and apologized to me.

"It's okay, I understand." I also put down my wand and said to Harry.

Today is the day to go to Hogsmeade. Harry didn't go because he didn't have an application form. I felt it was meaningless, so we both came to the training ground - the secret room that was used by our waste and started to practice magic.

When talking about why we set the driving range here, it is actually the result of discussion with the twins. When we told the twins about the idea of ​​finding a secret place as a secret base and driving range, the first choice they gave us was the room for responsiveness, which was the trolls on the eighth floor hit the opposite side of the tapestry of Sabahn Barnabas, but we gave up because it was too "wishes come true". If we suddenly think of some dangerous thoughts during the duel, it is easy to be realized immediately, which will affect the duel.

The second choice the twins gave us was the old classroom where the Eris Mirror was once placed, but we rejected it. After all, although it was hidden, it could still be discovered. What's more, we had to practice duels there, and the sound made would never be a little bit.

"In the secret room, it would be nice like the place where the Snake Monster once stayed." Ron said suddenly.

"Babystic?" Fred asked.

"Do you have any secrets that we don't know?" George continued.

"Ron!" Hermione was angry that Ron said this easily.

"What are you afraid of? Anyway, the matter is over, there is nothing there now." Ron said indifferently, and then he said the secret room, but his words fully exaggerated his role, as if without him, the secret room would not be able to be discovered.

"But we only have Harry, we can't call Harry every time we go there. Maybe Harry was practicing Quidditch at that time." I think it's not bad, but there is still a problem to be solved.

"Harry is a snake-like? Isn't this Salazar Slytherin's ability?" Fred said in surprise.

"Harry, maybe you might be Salazar Slytherin's great-great-great-grandson or something." George said half-jokingly.

"I don't believe that Salazar Slytherin in the world can speak snake language, just like I don't believe that Harry and Slytherin have anything to do with each other." I said lightly.

"Okay, we're talking about the driving range now, not what I have to do with Slytherin." Harry didn't want to continue the topic.

"Then let me leave this matter to you," Fred said.

"There are still places we don't know about Hogwarts, which requires our exploration," George continued.

The next month, the twins began to thoroughly check the entire Hogwarts, and for this they jumped on every window and balcony of the castle, used magic on every statue and portrait he saw, and spoke to the empty walls. During that time, the Gryffindors were worried - the twins who were always too energetic were stupid! But the harvest was abundant, and the twins paid the price of entering the infirmary twenty-three times in just one month, and exchanged for the discovery of seven secret rooms and eleven secret passages - among which there was another secret passage that could be opened without the need for the snake accent.

Seeing that Harry was really not in the mood to continue practicing, we left the secret room and prepared to go to the common room to eat something, or chat with Hagrid, or something, but on the way, we were intercepted by the twins.

"I thought you were going to Hogsmeade." Harry smiled embarrassedly. He was not in a good mood now.

"Oh, no, how could we—"

“—Where do you forget your buddy?”

The twins said in their unique way of speaking.

"Thank you." Harry really couldn't say anything except thanks.

"You know, we explored Hogwarts some time ago and found many secret passages-"

"——But the biggest contributor is this thing."

After saying that, Fred took out an old piece of parchment.

"What is this?" Harry looked at the parchment that looked shabby and ordinary. He didn't think ordinary things could be seen by the twins.

"This is the secret to our success from the professors," Fred said with his eyes narrowed, "When we were in the first grade-"

"—from Filch's office," George showed an exaggerated expression, "from the drawer with the words 'High Dangerous'."

"Let's live the map now? The ghosts told me this thing." I interrupted.

"I solemnly swore that I did not do good." Fred lit the parchment with his wand and recited a spell. Then, a wonderful thing appeared. Ink lines as thin as spider webs immediately began to appear from the place where the wand touched the parchment. They met with each other, crossed each other, and extended to every corner of the parchment; then the handwriting began to appear above the parchment, with large curved green characters, they were:

Auxiliary supplier of magic prank maker

Moon face, insect tail, big feet and pointed forks, gentlemen

Proudly offer

Live Spot Map

"That's amazing!" Harry exclaimed.

This is a map of Hogwarts Castle and the venues, but what is really worth noting is the tiny ink dots moving along the map, each ink dot marked a name with extremely small letters, and these names are the names of people we are familiar with, such as Felch, Professor McGonagall, etc.

"Through it, we escaped a lot of trouble-"

“———We have completed all the secret passages not shown above during this period.”

The twins said proudly.

"So, can I study this map for me?" I asked suddenly.

"Oh, yes." The twins did not refuse, but they felt a little embarrassed when they looked at the two of them.

"I've wanted to study this map for a long time, but you don't have to worry about being useless when you play tricks." As I said, I took out the map of the living spots I made myself. "This is the map I made myself. When I heard the ghosts say that this map was available, I started doing it, but it's only recently."

As I said that, I tapped the map with my wand and said "Nothing to hide". There were also pictures similar to the map of the live spots on the parchment paper, but the range was much smaller.

"The principle of this map is similar to the magic I used to detect invisible objects," I continued. "After starting, a wave with extremely strong penetration and diffuses around every once in a while, collecting the surrounding information and displaying it on this map. Because this is just a trial model, the display range is still very small, but I think it is enough for you to use."

"Wait, Lina, you mean-"

“——Can this map bring out Hogwarts?”

Twins asked.

"Of course, isn't yours?" I asked in surprise.

"Of course, just after taking it out of Hogwarts-"

“—It’s just a normal Hogwarts map.”

The twins replied.

"That's it..." I probably guessed the principle of this map.

Finally, the twins agreed to lend me the map to study, and during this period, my map was handed over to the twins, and I also promised that if I made a new map and handed over to the twins and Harry each as a New Year gift.

The main purpose of the twins coming here was to take Harry from the secret passage to Hogsmeade. I had no interest in this, not to mention that I have more important things to do now, which is to verify my ideas about the principle of this map. At night, when Harry and the others came from Hogsmeade, I almost traveled all over Hogwarts.

"What's wrong with you?" I originally wanted to tell them the news that I finally understood the principle of the Living Point Map. After all, if this is the case, I can copy it in large quantities, but I think their current situation doesn't seem to be very good.

"In the afternoon, we were in Hogsmeade, we overheard Minister Fogg and Professor McGonagall's conversation." Ron said nervously.

"We heard Minister Fudge say that Sirius Black is the secret person to your parents," Hermione continued quickly, "It was him-I mean Sirius Black betrayed Harry's parents."

"Harry-" I really don't know what to say, he still knows.

"Let me be quiet alone, okay? Please." Harry said, turning around and entering his dormitory.

There was no way, and now none of us could help him, so we had to leave the Gryffindor Tower and come to the auditorium to prepare for the Halloween dinner.

"By the way, Lina, what did you want to say to us just now?" Hermione asked to get rid of the dull atmosphere between the three of us.

"It's the map of live spots. I think Harry should have told you." I pulled the two of them into the corner, then took out the map of live spots and said to them, "Today I almost went around Hogwarts, and finally figured out the principle of this map. I think we will be able to get one in the future."

As I said that, I started the map, but I never thought that I saw a name on the map that should not appear on it, no, two names, and Hermione and Ron also saw it.

"It's him! Harry is in danger!" Hermione said loudly, and was about to run out.

"Don't panic!" I grabbed Hermione and looked at the map carefully.

"How can you still be so calm! That's--" Ron also reacted, but was interrupted by me.

"Shh-Don't make a noise, didn't you see another name? Something is strange!" I said to both of them.

"He? Isn't he dead? I've seen it in the book, and he still-" Hermione also noticed the name, but her long-term understanding made her a little panicked.

"We are going to find Professor Dumbledore now, but we cannot find abnormalities. In addition to being a secret passage, this person can enter the castle, there may be spies in the school." I said to the two of them, and they nodded and followed me to the door of the principal's office "without any abnormality". It happened that Professor McGonagall was here too.
