The Weasley twins have a great interest in the unknown.

Seeing Kewen's mysterious appearance at this time, the two of them couldn't hold back their curiosity, and immediately followed with a smile.

Kewen took the twins for a long distance, then stopped and asked, "Is your map still there?"

"Map?" Fred thought for a moment, and suddenly said, "You mean the Marauder's map?"

"Yes, that's the one." Kewen nodded and confirmed, "Lend it to me first."

"What?" George said in disappointment, "I thought it was a good thing for you to call us here, but it turned out to be just for the map."

Fred was equally disappointed, and nodded in agreement: "That's right, we've been a little bored recently, and we've finished exploring the castle, so the map is left in the dormitory, and I'll bring it back to you."

"Thanks." Kewen thanked, and then suggested with a smile: "Why don't you talk to those ghosts?"

"What's there to talk about with them?" Fred said reluctantly. "They'll just tell old, outdated stories."

"And it's tiresome to say it over and over again." George continued, "We're tired of hearing it."

"Ghosts can pass through walls." Kewen winked at the twins and reminded: "Maybe, they know some secret passages or secret rooms that cannot be displayed on the map, just like the 'House of Requirement' cannot be 'lived'. Click on the map' to show it."

After the twins heard the words, they both froze, looked at each other and saw the heat in each other's eyes.

Snapped!

Suddenly they raised their hands and clapped each other, and then Fred laughed excitedly and said, "Hehe, now we have something to play!"

"Hee hee hee..." George was also eager to try: "The adventure begins again!"

Kewen added fuel to the fire with a smile on the side: "You already know about last year's back room incident, you know, Harry used 'Parseltongue' to open the back room at that time, maybe there are other needs in the castle. Where can the cavity be opened?"

"Yeah!" Fred clapped his hands, but was a little embarrassed: "But we don't speak Parseltongue."

"It's already been prepared for you."

At the same time as Kewen said, he took out a small horn from his pocket. It was the kind of small horn with a capsule attached to the back, which could make a sound when the capsule was pinched.

Handing the trumpet to the curious Fred, Cowan explained, "I was nearby when Harry used Parseltongue, so I wrote down the pronunciation, but I only know the pronunciation of 'on', as for 'off' If so, you'll have to ask Harry."

"Then what is this?"

George took the small loudspeaker from Fred's hand, and after flipping through it twice, he tried to pinch it, but he endured it first, intending to listen to what Cowen had to say.

"This is an ordinary alchemy item."

Kewen pointed to the small horn: "I enchanted the 'Parseltongue pronunciation' of the opening password on it, and when you get the 'closed' pronunciation from Harry, you can enchant it yourself, right? It should be fine for you, right?"

"Of course no problem!" George was excited, and then squeezed the capsule.

"Heisei Hassa..."

A 'hissing' sound came from the small speaker, and the sound was a little scary.

But the twins seemed even more excited.

Seeing this, Kewen finally pointed out: "You can look for it in the castle in the future. As long as there is a serpentine relief, you can use this thing to try it. Maybe you can open any new secret rooms."

"As expected of our good brother!" Fred raised his hand excitedly and patted Kewen on the shoulder.

George couldn't help but suggest, "How about we go to the Basilisk's secret room tonight?"

"Don't!" Kewen hurriedly stopped: "You still have to get the 'shutdown password' before you talk about it, otherwise you will be deducted points if the professors find out."

"Okay..." George's excitement dropped a little, but he still listened to Kewen's advice.

"Let's go!" Fred greeted: "Go back to the dormitory first and get Kewen's Marauder's Map."

At the start, the three walked out of the corridor together and returned to the dormitory...

Regarding the plot that will take place this year, Kewen has already finished recalling at dinner.

Compared with the previous two years, this year's plot is not in danger of death for Harry, so it should not be necessary for him to escort secretly like last year.

And this year, he has another important goal that needs time to achieve, and he basically has no energy to pay attention to any plot.

Therefore, Kewen planned to get the 'Marauders Map' first, use it as a proof, and reveal the secret to Dumbledore in advance, and then let Dumbledore think about the arrangement after that.

In the dormitory, Kewen successfully obtained the Marauder's Map. After opening it, he glanced at it and found that the name of 'Peter Pettigrew' was displayed on the map, which was located near Ron.

Putting away the map, Cowen rejected the twins' request and left the Gryffindor common room.

Walking out of the door of the 'Portrait of Fat Lady', Kewen raised his hand and used the 'Guardian Charm' to send a message to Dumbledore, and then went straight to the direction of the principal's office.

On the way, Cowan got a response from Dumbledore, and a patron saint in the form of a phoenix sent Cowan an office password.

Soon after, Kewen entered the principal's room with a password and knocked on the door.

"Good evening, Mr. Principal."

Entering the principal's room, Kewen greeted Dumbledore in a pajama robe.

"Good evening, Kewen." Dumbledore put on the glasses hanging on his chest, then raised his head slightly, and asked, "What did you think of, do you need to tell me in time?"

"Yes, Mr. Principal, sorry to disturb your rest."

"Don't say that, little Kewen."

Dumbledore said with a smile, then waved his hand, prepared dessert and drinks for Cowen, and invited another chair.

"Let's sit down and talk."

"Not first."

Kewen didn't sit down, but stepped forward to the desk, took out the Marauder's map from his pocket and unfolded it.

"What's this?"

Dumbledore leaned slightly and observed the blank parchment placed on the desk by Cowen. After getting no results, he couldn't help but jokingly asked, "Don't tell me, this is like the diary last year again. thing."

Kewen smiled and shook his head, then took out his wand and pointed it on the parchment map, and recited, "I solemnly swear that I have done nothing good."

A jet of ink was instantly rendered on the parchment...
