Harry's behavior during the day made the two friends worry about him, and Ron followed him for an afternoon, worried that he would do something terrible, but Harry seemed to forget about it after vowing to kill Pettigrew and behaved normally, but when Ron fell asleep, Harry, who was lying on the next bed, suddenly opened his eyes.

He stood in front of the window, looking at the moonlight outside the window, a little hesitant, and Ron, who was lying on the bed next to him, muttered a dream that no one could hear clearly.

"I'm sorry, my friend." Harry muttered, "But there are some things that I have to do alone. ”

He took the Golden Sutra of the Sun under his pillow, put on his invisibility cloak and left the dormitory, and the empty hallway was full of Soso's footsteps and headed straight out of the Gryffindor common room, the portrait of the fat woman dozing, she seemed to hear a muffled voice chanting something, but she only saw a white shadow fading rapidly.

From a spirit perspective, Harry easily walked through the door of the Gryffindor common room, and he crept his way to Filch's office.

"When we were students, we used to make a very magical magic prop, which James used the spell on Hogwarts Castle to bypass some of Hogwarts' anti-magic spells and fixed the tracking charm on the map - every Hogwarts student has a strange contract connection with this great school of witchcraft and wizardry, and the Sorting Hat is a very important part of it, and when the students are assigned to various houses by the Sorting Hat, they have reached a mysterious contractual connection with this castle."

"When professors receive offers of employment, they sign them to confirm their connection to Hogwarts."

"There are many mysteries in this castle, all wizards who have not signed a contract will be suppressed in some way, and wizards who have signed a contract, Hogwarts Castle can monitor some things, such as their location - this magic prop is made from this, it can monitor the wizarding activities of the entire Hogwarts Castle."

"James didn't say how he did it, but I'm guessing he found the key items left behind by the headmasters, and as the headmasters, they are entitled to use these contracts to bypass the anti-'tracking spell' that is preserved at Hogwarts Castle."

"We've poured our thoughts and memories into this magical map to escape the school's janitor and wander around at night, on that map I'm called Moonface, Sirius Bigfoot, and your father, James...... He is called Pointed Fork, and Peter Pettigrew is called Wormtail. ”

"The origin of these nicknames is related to our Animagus Transfiguration, in order to alleviate my lupus, James they taught themselves Animagus, Sirius is a big black dog, so it is called Bigfoot, James is a deer, and Peter Pettigrew, is a mouse."

"You know, Potter, everyone's Animagus has to do with their personality and bloodline, and even fate."

"We didn't pay attention at the time, because Peter Pettigrew is so weak and timid, he's like a little brother who follows James."

"On the night of your father's death, I realized that there was a traitor between us, and he had taken refuge with Voldemort! But I don't believe it's Sirius, listen to me, no one is more loyal than him, so he's a big black dog. And the dead Peter Pettigrew...... The Animagus are wizards of rats, and although they are not unbelievable, they have betrayal hidden in their souls. ”

"When I saw the picture of your friend with the mouse on his shoulder, I was even more sure of my judgment. Pettigrew isn't dead and has been with you lately. ”

"I can't tell you what the truth is, it's up to you to investigate and judge."

"The map of the living point left by James can help you, as long as Pettigrew is still hidden in Hogwarts, he will not be able to escape the monitoring of the map, but you should be careful, when Pettigrew appears on the map, he will be shown as a wormtail, the map cannot be cracked with the normal Transfiguration Charm, you need to raise your wand and say to the map: I solemnly swear that I have not done anything good."

"After use, read it out; The prank is done' on it. ”

"James was caught by Filch once when he was close to graduation, and the map was confiscated, and it should be in his office now."

Harry approached the door of Filch's office, and in the spirit vision, he saw a wave like a black water wave behind the office, and a suction force came from behind the door, Harry was a little surprised, because this was the first time he had found anything that could affect the spirit world from the physical world!

He listened through the office and heard Filch's voice coming from inside, "Master, Harry Potter didn't say anything to Dumbledore, the professors' reactions are normal, and the news from the Ministry of Magic is true...... There was indeed a terrible dark wizard who destroyed the entire Ministry of Magic, leaving the Aurors like lost dogs. ”

"Well done, Filch!" Harry could clearly hear that it was Malfoy's voice.

In the spirit vision, Malfoy is like a distorted light and shadow, in the center is a thick shadow like a black dragon, wrapped in a transparent light like glass, Harry wants to see this distorted light and shadow clearly, he borrowed the power of the "Golden Sutra of the Sun", Malfoy's essence is like a glimpse, it is a withering young dragon, holding a black-skinned magic book in his hand.

"Who?" Malfoy suddenly became alert, and he looked suspiciously.

Filch replied cautiously, "No one, master, under your spell, no one can sneak in, not even Harry in the cloak of invisibility. ”

"I can't stay here for too long." Malfoy was suspicious and didn't want to say anything more: "Be careful, Filch!" With that, he turned into a puff of black smoke and left.

"It's really the Black Book of the Dead." Harry had seen it.

He looked at the place where Malfoy disappeared for a while, and it wasn't until Filch also sneaked out that Harry came to his senses, if it was before, he would definitely chase after Malfoy to see what plans Malfoy had, but now Harry, who was tormented by hatred, only wanted revenge, especially since Pettigrew might not only be the traitor who betrayed his parents back then, but also might be hiding Voldemort's soul.

Harry couldn't tell, which one did he hate more? But with this opportunity to kill these two most important enemies at once, he would never want to let go.

"The live map is flying!" Harry cast the Flying Charm, but nothing happened.

Harry wasn't angry, he had long suspected that the map might no longer be in Filch's hands, and if there was anyone at Hogwarts who knew best about Filch's office, who knew the naughty things best, who knew the people who were making trouble and wandering at night, it would be the Weasley twins, and the Weasley brothers would most likely know the whereabouts of the map - but Harry's time was running out.
