"What a fun thing." Silver looked back and forth at the parchment that looked quite thoughtful. "A very clever technique."

Snape impatiently tapped the table with his fingers. "Silver, I asked you to make an accurate identification of this broken parchment, not to make you sigh at the making of this parchment-I suspect that Potter used this parchment to cross the Dementor's guard and go to Hogsmeade privately. So you must give me an accurate answer, what is the mystery of this parchment?"

"Don't worry, Professor Snape." Silver replied calmly. "I almost know the secret of this piece of parchment, but I still need a password to crack it."

"Cracking the password? I've tried all the curse techniques I know..."

"The commands of magic props are unique, and ordinary spell removal techniques are useless." Silver smiled. "What's more, the making of this parchment is very unusual."

Silver walked to the fireplace, and suddenly he threw the parchment into the swaying fire.

"What are you doing!" Harry, who was standing aside, shouted. Lupin stopped Harry who wanted to rush up.

"Shut up, Potter, Silver certainly has his intention to do this." Although Snape didn't understand why Silver did this, he was unwilling to give up any chance to hit Harry.

Silver waved her wand, and the red fire suddenly rose and turned into a charming green. The green flames held up the parchment paper, wrapping it up and down. Silver stretched out his right hand and grabbed the parchment paper in the flame without any obstacles.

"So that's it." Silver nodded. He touched the parchment with his wand. "I solemnly swore that I did not do good." Ink lines as thin as spider webs immediately began to appear from the place where the wand had just touched. The lines converged with each other, crossed with each other, and extended to every corner of the parchment. Then the handwriting began to appear above the parchment, with curved green characters, which were: the auxiliary supplier of the magic prank maker Moon Face, insect tail, big feet and pointed fork, gentlemen proudly presented the map of the living spots.

Snape grabbed the parchment map. "So that's it, Porter, you actually have a wonderful Hogwarts map." Snape's lips pursed tighter. "Moon face, insect tail, big feet and pointed fork." Snape snorted coldly.

Snape put the map of the living spots on his desk and gestured to Lupin to see it.

"Lupin, Porter, he has a very interesting map that fully marks all the details of Hogwarts Castle and the venues. Oh, and there are even seven secret entrances."

Snape laughed maliciously: "I'm afraid Potter is going to and from Hogwarts through these entrances. I was shocked by the extent of your ignorance of the school. Maybe you have to pass the Dementor's guard every day and leave Hogwarts..."

"I don't!"

"Shut up, Potter." Snape said in an unquestionable tone. "You look more and more like your arrogant father. Maybe a little Quidditch's talent gives you father and son the confidence to surpass the rules?"

Lupin tried to interrupt: "Severus, maybe this map is just what Harry just got..."

"My student Malfoy and his two companions witnessed Porter's head appearing in Hogsmeade, oh, I think Mr Porter may also have a very precious invisible cloak..." Snape said without hesitation.

"This map even marks everyone in the castle. With this map, you can master the every move of everyone in the castle. This is not something that ordinary wizards can do. If Joko can sell such valuable products, then I think our students should all go to Joko as apprentices instead of wasting their youth in Hogwarts!"

Snape stared at Harry with his malicious little eyes. "I think our savior needs a little lesson - when we are all afraid of him and try to protect him from his death under Sirius, the savior Potter, without any hesitation, traveling freely between Hogwarts and Hogsmeade through a wonderful map, swaggeringly shopping and enjoying life on the streets. Potter, you will be responsible for your actions, I will keep you from locking in for a week. And I will also report this to the principal, and I personally think you are not qualified to continue studying in Hogwarts."

"Severus, he is just a child after all!" Lupin said.

"But he must be responsible for his actions! Do you think Potter is a good idea to run out of the castle without authorization? Do you think Sirius will be nostalgic and not attack him?" Snape waved his hand angrily.

"Potter, you can go back, your lockdown will start tomorrow." Snape turned to Harry and said.

Harry was about to argue something, but Lupin stopped him with his eyes, so Harry had to leave.

"Lupin, your blind cover will only kill Potter. Do you think your friendship was indestructible?"

"Severus, are you doubting me?"

"Two professors, I think you can pause for a while, I discovered something very strange," Silver said.

Snape and Lupin looked at him in confusion.

Silver pointed his hand at the map.

"I think, maybe professors you will be interested in this."
