The wait was torturous, and Harry had to admit it.

Ever since he knew the truth, he had been thinking about finding Sirius all the time.

But the reality is that it's only Monday today, and you won't have a chance to leave school until at least the weekend.

It was Potions class on Monday morning, and Snape's face was still so cold that Harry had to go to class with Slytherin.

The annoying Malfoy finally removed the bandage from his arm and kept mimicking the movements of the Dementors in front of Harry.

"Potter is like a frightened quail, foolishly spinning around in the sky." He smirked, "I bet he definitely remembered growing up in a Muggle kennel." ”

Harry didn't want to pay attention to Malfoy, but he was dancing too much.

"Malfoy, shut up!"

"Ha, Potter is in a hurry, he is in a hurry!"

Eventually, Ron threw a crocodile heart at Malfoy's face. Kano secretly sent a spell that sent Malfoy's mouth full of shredded flesh.

Snape immediately deducted fifty points from Gryffindor, and Carnot and Hermione waved at their classmates at the same time, meaning that they were all covered.

The Gryffindor students nodded wordlessly, and it wasn't the first time that Snapra had been offset. There were two big brushes who said that they were also happy to see Malfoy deflated.

In the afternoon Defence Against the Dark Arts class, Professor Lupin finally returned. His face was very pale, as if he had been seriously ill.

Of course, this is the after-effect of the werewolf transformation.

Seeing Kano sitting in a chair, Lupin's eyes lit up. Kano nodded at him, and his spirits seemed to improve a lot.

"How's everyone doing?" He greeted the students with a smile.

The students complained about Snape's misdeeds, and Lupin's face twitched slightly when he heard that the previous lesson was about werewolves.

"He also left us homework." Neville muttered, "The essay assignment for the last class was 'How to Identify and Kill Werewolves.'" ”

Lupin seemed to be choked up: "He's not a classroom teacher, everyone can be exempted from this assignment." ”

The students cheered, and the trio looked at each other, aware of Snape's sinister intentions.

Lupin then brings a high-quality Defence Against the Dark Arts lesson, and the main character today is a Hinkpunk, made of smoke, with only one leg and a lantern in his hand.

They carry lanterns in dark swamps and lure people into the mud to die.

After class, Kano was left behind, and Lupin hurried over to him.

"Is there any result from the study?" He asked, muffling his voice.

"Of course." Kano smiled, "I didn't miss the full moon in October. ”

"Next month, we'll see the results."

Lupin nodded excitedly.

A week flew by, and on Saturday morning, Kano received a report from Kreacher and nodded to the trio in anticipation.

"When I heard that you are going to embark on our glorious path, my brother is very pleased."

In the corner of the common room, Fred pretended to wipe tears with emotion.

"That's right, it's a Christmas present this year." George pulled out an old piece of parchment, "We don't need it anymore, I hope it will work you as well as it does us." ”

Harry looked at Kano in confusion, and Kano tapped the twins on the shoulder.

"Show Harry a show, don't get hung up."

"Okay." George tapped his wand on the parchment: "I solemnly swear that I will not do good." ”

The ink outlines a detailed map of Hogwarts, including the entrances and exits to the various secret passages, as well as the real-time location of each person, whose name is marked next to a dot representing their location.

At the very top is a line of writing in green ink.

"Moonface, worm tail, big feet, and pointed forks, gentlemen who help magic pranksters,

Introducing Grandly,

Live point map. ”

Fred solemnly placed the map in Harry's hand: "When you're done, remember to say 'Prank Over' and the image will disappear." ”

"These four pioneers are very great, and today we pass it on to you, and I hope you will use it well and not let it down." George is also serious.

Harry excitedly took over the map of the living spots, as if he had taken over a flag.

Kano couldn't help but smile and nodded, "With your invisibility cloak, let's take action." ”

Soon, the trio and Kano were in the hallway of the fourth floor of the castle, where a tall statue of a one-eyed hunchbacked witch was placed.

"This is Gusmo's Gonzida, who invented the cure for dragon pox." Hermione said, looking at the base of the statue.

Harry sighed heavily and bowed slightly. After searching for genealogy in previous years, he knew that his grandparents had died of the disease, just before he was born.

Kano nodded at the statue: "Left and right separated." ”

The statue's back opened silently, and the four merfolk rushed in, entering the secret passage through a stone slide.

"Fluorescent flickering." Harry lit his wand and cautiously moved forward in front, Kano breaking behind.

A detour of the low passage, then the road began to rise, and a long staircase appeared in front of it.

After ten minutes of walking, Harry opened a trapdoor overhead and found himself in the cellar of Duke Honey's confectionery.

"Will the owner of Duke Honey find out that we are coming out of here?" Hermione said worriedly.

"Duke Honey has only opened in the past ten years, and the boss may have walked through this secret passage when he was a student." Ron reminded, "Isn't it obvious that you don't put anything in the cellar and don't have a spell to lock it?" ”

"Needless to say, usually the boss may turn a blind eye, but now it's not Hogsmeade Week. Come on in. Harry beckoned to the two of them and ducked under the invisibility cloak.

Kano cast a disillusionment spell on himself and whispered to the trio to show them the way.

Soon, the four invisible men arrive at a stinking garbage dump, where a large black dog is happily shaving food on the garbage heap.

"Is it really? I've seen it twice! Harry exclaimed quietly, "The first time was outside the house that night, and the second time was at the Quidditch Arena. ”

"That's him, go ahead." Kano nudged Harry, and Harry slipped out of the cloak.

"Sirius? Sirius. Black? ”

The big black dog shuddered, and turned his head to see Harry, who was wearing glasses and had unkempt hair, his mouth ridiculously open.

After being stunned for a few seconds, the big black dog ran away, barking very clumsily as he ran.

"Sirius, don't go! I know it's you! Harry hurried after him.

"Sirius! Godfather! ”

The big black dog stopped, changed back into his human form in the corner, and hugged Harry blankly as he rushed up.
