Hogwarts starts with stealing power.

After knowing the magical function of the Marauder's Map and that Harry has an invisibility cloak, this choice can be answered with just a tap.

Everyone said in unison: "Go!"

Fortunately, Harry's invisibility cloak was very large, so everyone huddled inside the cloak and moved around quietly.

The auditorium is on the second floor, so they started patrolling from the second floor.

During this time, I met Professor Sprout.

The professor passed by them and the little wizards all held their breath, feeling a little nervous.

If it was just one person, they wouldn't be so worried, but now so many people are under the invisibility cloak...

Harry was having some wild thoughts. With so many people around, would the invisibility cloak's ability to hide his presence become ineffective?

After waiting for a long time for Professor Sprout to pass by them, the little wizard couldn't help but breathe a sigh of relief.

As they were about to continue walking down, Professor Sprout in front of them suddenly turned his head and looked at the corridor behind them with a puzzled expression.

The little wizard stopped immediately again.

She looked left and right, frowned and whispered, "Why does it feel a little wrong?"

Following his feeling, Sprout returned to his original place.

The young wizard held his breath again.

This time, even though Professor Sprout passed by them for a long time, no one dared to relax.

Only when Sprout disappeared from their sight did they heave a long sigh of relief.

George said, "It seems that the professor has a very keen sense. We should pay more attention to our breathing in front of the professor and not let them notice it."

The other little wizards couldn't help but nodded.

After inspecting the second floor, they stood at the fork in the road, somewhat hesitant about whether to go to the third floor or the first floor.

Finally they decided to go to the third floor to take a look.

Because when they looked down, they found several professors walking around on the first floor.

The young wizard decided not to take the risk.

Although Professor Snape repeatedly emphasized in front of them that the Fat Lady would not escape and could not leave Hogwarts.

But in this case, the Fat Lady still left the frame, which is enough to show that she encountered something dangerous, so she had to leave.

In such a frightening situation, even if you cannot leave, you will most likely walk back and forth on the first floor, hoping to get out.

This is also the reason why there are so many wizards patrolling back and forth on the first floor.

After the little wizard came to the third floor, he looked at the picture frame one by one.

The expressions of the characters in those frames were all terrified, completely different from their usual calmness.

The corridor was empty, but the picture frames began to talk to themselves, as if they were exchanging information with other picture frames.

From time to time, a few mutterings flashed through the air, creating a tense atmosphere.

"She was scared, so she left."

"She said she saw Sirius Bright. How did this heinous man get into Hogwarts? None of the Dementors outside noticed him!"

"Oh, poor fat lady, I hope she won't be found by the bad guys. I understand and sympathize with her feelings. It will probably take her several days to calm down."

"Should we prepare enough food and water for the Fat Lady? Can she handle the pressure alone?"

Suddenly, a voice that was obviously not from the picture frame was heard in the empty corridor. It sounded like the little wizard was talking.

The voice is a little childish.

"Do you know where the Fat Lady is? I need to find her urgently. Please tell us."

The expressions of the people in the frame froze for a moment. The chattering sounds all stopped, and all of them turned their heads to look in the direction where the sound came from.

That was a deserted ground!

As if sensing that these frames were unfriendly to the sudden sound, another more obvious voice belonging to the little wizard rang out.

This is a female voice.

"She's missing, the door to the Gryffindor common room can't be opened, a large number of wizards are trapped inside, and we urgently need the Fat Lady's help."

Hermione's voice was sincere and polite.

But as her sudden voice rang out, all the characters in the frames fled from the frames quickly like frightened birds.

When they left, Harry and the others heard their voices.

"It's really weird. I actually heard the voice of a little wizard in an empty corridor. When did Hogwarts become so weird?"

"Run away quickly. Maybe this is how Sirius fooled us. The Fat Lady was fooled and fell for it."

"Where are we escaping to? Don't abandon me, wait for me!"

Little wizard:......

Harry's voice came: "I said you are too anxious. These frames don't believe us, how can they help us!"

They were arguing as they walked.

Hermione: "Harry, only the picture frame can know the whereabouts of the picture frame. If we want to find the Fat Lady quickly, we must rely on their help."

Ron: "That's what I thought, so I asked."

Harry couldn't help but ask, "If this method is useful, why doesn't even the professor use it? If the professor doesn't even trust the picture frame, how could he trust the little wizard?"

The others fell silent again, and Harry's words made sense.

Just then they came to a fork in the road, and Lin Xia asked, "Shall we continue up?"

The young wizards replied in unison: "Go up."

When we arrived at the 4th floor, coincidentally, several professors came towards us, including Professor McGonagall.

The young wizard immediately stuck to the wall, held his breath again, and did not blink.

Professor McGonagall walked past them, speaking hurriedly to the other professors:

"Headmaster Dumbledore has been notified. He is in the Gryffindor common room and is planning to open up another passage. We need to go over and help stabilize the space."

After Professor McGonagall left, George immediately suggested, "Why don't we follow them and see. I'm quite curious about what the headmaster is going to do."

Fred immediately agreed: "I agree!"

Lin Xia also said, "Let's go and have a look. It might be a valuable learning experience. We rarely see the principal take action. He is a very powerful wizard."

Harry and his two companions were a little hesitant at first, but after hearing what Lin Xia said, they were immediately tempted. Who doesn’t yearn to become a powerful wizard?

So everyone hurried to the Gryffindor common room.

As soon as they walked in, they saw a dozen professors gathered at the door, surrounding Dumbledore.

The professors didn't squeeze too close, leaving plenty of space, so even the little wizard could see Dumbledore's expression and attitude.

He said solemnly: "We have to call the little wizards in the common room out as soon as possible, and not only Gryffindor, the other three houses are also at risk of being lost.

Sirius was able to come in without anyone noticing, and we can't be sure whether he has left the school. We must first ensure the safety of the little wizard!" The other professors nodded solemnly.

Dumbledore waved his wand and chanted with me: "Gryffindor, you are a brave Gryffindor, your light shines on the earth, Hogwarts is under your leadership..."

This spell is not spoken in the form of magic words, but can be used by chanting ordinary language.

But it is obvious that this passage has been specially processed.

When the professor's voice merged with the principal's voice, the little wizards could clearly feel that every word they said could vibrate with the air.

The surging magic power gathered together silently and exerted force in a certain direction. Circles of invisible ripples rose up and the ground seemed to tremble.

They could sense that something was vibrating, but the environment was completely calm, and they didn't know where the tremor came from.

Until they saw the place where the Fat Lady's frame was originally, the space suddenly twisted into a black hole, and then the black hole grew bigger and bigger, turning into a door, and finally completely solidified.

The young wizard then realized that the vibration they had felt before was not the ground shaking, nor was it the entire Hogwarts shaking, but the vibration of the air!
The vibrations of the air touched their skin, causing them to tremble all over.

The next second, the door to the Gryffindor common room was opened!
The professors filed in. They had to check on the little wizard.

Dumbledore was the last to enter.

Before he left, he suddenly looked back and looked in the direction of Harry and the others, then he quickly looked away.

The little wizard's heart skipped a beat, wondering whether the principal had discovered it or not.

Once the headmaster had entered the common room, the Weasley twins reacted quickly, tugging at the sleeves of the other young wizards and rushing out.

Only after they retreated back to the auditorium on the second floor did the twins feel relieved.

George said, "It's late at night and the little wizards are sleeping. The Fat Lady would rather leave the frame than open the door for Sirius. I'm sure the little wizard will be fine."

Fred added: "When that happens, there will be a lot of little wizards rushing out, and they might bump into us and cancel the effect of the invisibility cloak."

Harry frowned, unable to tell whether he felt lost or regretful.

His main purpose during this patrol was not to find the Fat Lady, but to see if Sirius was there.

He thought to himself: With so many wizards patrolling, Sirius would have run away long ago, right?

Lin Xia noticed Harry's absent-mindedness, thought for a while, and said cryptically:
"Harry, you can actually take a look at the Marauder's Map. Maybe you can find what you want."

Ron couldn't help but say, "The Marauder's Map only records the traces of the living, and doesn't record the dead souls in the frame. How can we use it to find the Fat Lady?"

Ron misunderstood Lin Xia's words, but they enlightened Harry.

Yes, he could borrow the Marauder's Map and see if Sirius Black was still at Hogwarts!
Harry looked at Lin Xia gratefully and borrowed the Marauder's Map from the twins.

The twins also wanted to see the current situation, so they simply spread out the map and observed it one by one.

"Look, there are some little wizards outside the Gryffindor common room, and there are professors guarding outside."

"They are really fast. There are professors in the common rooms of the other three houses, and the young wizards are starting to come out."

Some students moved quickly and reached the third floor in the blink of an eye.

If they had lingered in the Gryffindor common room and waited until they saw the little wizard appear before leaving, they would probably have left too late.

The twins immediately said, "A little wizard has arrived. We need to put away the map!"

Not only that, they have to come out from under the invisibility cloak.

It seemed as if a crack was created in the air. The crack gradually became dyed with color, and then the figure of the little wizard appeared.

Harry still had a worried look on his face.

After just a few minutes of observation, he did not see Sirius.

The names are too dense. Everywhere you look, you see names. I don’t know if I might have missed some places.

"Harry, Ron, you have arrived at the Great Hall early!"

Neville and Mikkel soon arrived at the Great Hall. Neville, wearing a furry sleeping cap, rubbed his eyes and said with great surprise.

The clothes he was wearing were also very furry, with a blue polka dot pattern. This was the pajamas that Neville often wore.

Mikel was also wearing pajamas, which were red and yellow plaid. This was the favorite pajamas of Gryffindor students and a hot-selling item in the school.

Little wizards arrived one after another.

Because everyone was woken up by the professor, most of the little wizards were wearing pajamas.

The situation was so critical, and the professor sounded so serious, that they didn't even have time to check their clothes.

Professor McGonagall hurried to the Great Hall and called over the prefects of each college, asking them to calm the little wizards and maintain order.

She said, "Let's sleep on the floor in the auditorium first, and we'll talk about everything tomorrow morning."

Percy straightened his back, held his head high and said, "Yes, Professor, I promise to complete the task!"

Professor McGonagall was about to leave when she suddenly thought of something and waved her wand.

Thousands of floppy purple sleeping bags appeared on the floor.

The young wizard fell asleep again after being comforted by the prefect.

Mainly because we were woken up in the middle of the night, everyone was a little confused, and there was a professor on duty, which increased the sense of security.

They only knew that something dangerous seemed to have happened, but they didn't know the specific situation, so they could only fall asleep.

"Harry? Harry!" Ron called Harry several times.

Harry came back to his senses, "What's wrong?"

Ron said, "Let's lie down and sleep too. We have a tough battle tomorrow!"

Harry hesitated: "But..."

Ron pulled Harry to lie down and yawned loudly.

"Go to sleep! Lin Xia and the others have returned to the Hufflepuff queue to sleep. It will be awkward if we don't sleep. Professor Snape is staring at us in the left corner!"

Harry fell asleep with his mind wandering.

When the first ray of morning sunlight shone on Hogwarts, the young wizard was awakened by the scorching sun and gradually regained consciousness.

Dumbledore suddenly appeared on the stage, tapping the glass with a silver spoon.

There was a crisp "ding dong" sound, and all the students heard it.

The sound seemed to carry a magical power that quickly brought the little wizard from his dazed state to clarity.

Seeing that everyone was up, Dumbledore said, "Something happened yesterday. The Fat Lady, the doorkeeper of the Gryffindor common room, suddenly left the frame.

After investigation, she saw Sirius Black and did not dare to open the door for him, so she encountered violent damage. The professors and I need to conduct a comprehensive investigation of the castle. "

As soon as Dumbledore finished speaking, Professors McGonagall and Flitwick immediately closed all the doors of the Great Hall.

Dumbledore continued, "For your own safety, I would like the prefects to guard the entrance to the Great Hall, and I have entrusted the Head Boy and Head Girl with responsibility.

You need to stay in the auditorium first, and report to me immediately if anything happens."

He paused and said to Percy, who was standing solemnly below the stage: "Send a ghost to deliver the message."

Percy nodded immediately. (End of this chapter)
