Filch likes to physically punish students, and whenever the lights go out, he likes to run around the corridors, like the Gestapo, to catch the little wizards who don't come home at night, and then let them clean the toilets.

Since he became the warden of the castle, all the students have avoided him like a plague.

However, Wang Xu, who has watched the Harry Potter seven-part series, knows that this squib, who is hated by the students, is one of the few people who did not leave when the decisive battle came, and chose to fight Voldemort to the end at Hogwarts.

You must know that at that time, it was already the seventh Harry Potter book, Dumbledore was dead, the Dark Lord was resurrected, and the entire wizarding world was shrouded in shadows.

When the decisive battle came, many wizards chose to leave, including Stetelin, Ravenklai, Hufflepuff, and Gryffindor.

In this stormy situation, many people think that to stay is to wait for death.

Filch, a Squib but greater than many wizards, removed the strips of cloth from his mop as a weapon, locked his cat in his office, and chose to stand up and fight the Death Eaters to the death.

Wang Xu admires this kind of loyal person very much, and knows that what Filch needs is not pity, but an opportunity, and it just so happens that Wang Xu can provide him with this opportunity.

One garbage technique, two garbage martial arts, I can't say how powerful Filch can become, but it can make him narrow the gap with ordinary wizards.

Of course, there is a premise in this, this opportunity must be grasped by himself, and the opportunity waits for no one.

Pushing open the office door, Wang Xu walked in humming a little song to prepare for his lucky experiment.

He instructed Twinkle to find twenty colored marbles and hide them in all corners of Hogwarts, intending to play a treasure hunt with Harry.

In order to motivate Harry's enthusiasm, or let him bloom his luck, Wang Xu decided to bet on a secret, and this secret was something Harry couldn't refuse anyway.

Tick-tock, tick-tock...

The floor clock in the room kept ringing, and time was quietly leaving.

Wang Xu is a very patient person, he just sat in the chair in the office, letting time slip through his fingertips.

... Ten o'clock in the evening...

Knock knock!!

"Professor, are you in there? I'm Harry! ”

After waiting for more than an hour, Harry's voice resounded outside the door, making Wang Xu, who had closed his eyes and recuperating, slowly opened his eyes.

"Come in." Wang Xu spoke slowly, sat on the chair and poured himself a cup of herbal tea.

Click...

The door opened, and Harry, who was wearing a student uniform, pushed open the door and walked in from the outside, asking, "Professor, are you looking for me?" ”

"Sit down." Wang Xu pointed to the chair opposite, picked up the cup and took a sip of herbal tea.

Harry didn't know what Wang Xu was looking for him, so he sat down in a daze, his eyes dazed.

Wang Xu put down the teacup, stroked the ring on his hand, and said, "I guess Professor Dumbledore came to you to give you a mission, and this task is related to Professor Slughorn, strictly speaking, for Professor Slughorn to hide a secret, right?" ”

"Professor, I, I don't know what you're talking about." Harry looked a little flustered, not daring to look at Wang Xu's gaze.

Wang Xu smiled, pointed upstairs, and said, "My office is on the second floor, and the principal's office is on the third floor, if you have the architectural drawings of Hogwarts, you will find that the principal's office is above my head." Normally, people sitting downstairs can't hear the conversation upstairs unless the people above are singing karaoke. I'm an exception, though, I'm more perceptive than the average person, and if I want to, it's nothing. ”

"Professor, I..."

"Don't rush to refute, I'm not trying to get anything from you, but I can give you some necessary help. Let's make a game, I have hidden twenty stained glass beads in the Hogwarts castle, and I don't know the location of these glass beads. In an hour's time, if you find more glass beads than I do, I don't think you need to worry about Professor Slughorn's affairs, because I know all the secrets you want to know. ”

Wang Xu looked up at the floor clock, turned his gaze to Harry, and said with a smile, "Do you want to try it?" ”

"Professor, what if I lose?" Harry asked weakly.

Wang Xu spread his hands and replied, "Then there is no way, the questions you want to know can only be found on Professor Slughorn by yourself." It may take months for you to know about this until the second semester of the semester. ”

Harry didn't speak for a while, and after a long time he said, "I promised..."

"Come on, the game begins." Wang Xu pointed to the door, signaling for Harry to take a step first.

Harry took a deep breath, opened the door and rushed out.

Wang Xu glanced at the floor clock, it was ten o'clock, how effective the lucky potion was, and the answer was about to be revealed.

"Goo-dong!" Wang Xu picked up the teacup and took another big sip.

Tea with lucky water poured down his throat and into his stomach, and the feeling of happiness welled up in his heart.

In the desks of the classrooms, in the corners of the corridors, under the carpets in the break room, in the tub of the restroom.

Wang Xu didn't open up his martial arts perception, but just followed his heart and went to find those hidden marbles.

As time passed, the expression on Wang Xu's face became more and more serious.

It's been fifty minutes, and he's only found seven marbles, and sometimes he follows his inner guidance to find them, only to end up with nothing.

"The kitchen may be a catch!" In Wang Xu's heart, this thought naturally arose, as if he should think like this.

Wang Xu played with the seven marbles in his hand, walked down the stairs, and came to the kitchen door.

Before he could push the door, the kitchen door opened on its own, and Harry walked out of it with a beaming face.

Seeing Harry here, Wang Xu frowned slightly and glanced at his right hand.

Harry was holding a handful of marbles in his hand, so many that he tended to be unable to catch them in one hand.

"At least eight or nine!" As soon as Wang Xu came up with this idea, he saw Harry running towards the Potions classroom without looking back.

The Potions classroom was also in the basement, separated from the kitchen only by Hufflepuff's bedroom, more than a dozen meters away.

Under Wang Xu's gaze, Harry plunged into the Potions classroom, and soon the room sounded with exclamations of joy, Wang Xu walked in to take a look, and there was actually a glass ball from the bookcase and the medicine pot.

"Professor, I've found eleven of them!" Harry ran over with an excited look on his face, a handful of marbles in his hands.

Wang Xu just glanced at it, and he could predict that there were no more marbles and no less, exactly eleven, and according to the rules he had said before, he had already lost.

"Awesome, awesome!" Wang Xu opened his hand slightly, and seven marbles rolled down from his fingertips, falling to the ground like pearls with broken threads.

Harry didn't know what Wang Xu said again, so he scratched his head embarrassedly and smirked: "I have a talent for finding things since I was a child, and my cousin Dali lost things, and I helped him find them." ”

Wang Xu smiled without saying a word, he didn't tell Harry that he had drunk the lucky water before the game started.

He didn't tell Harry that in the huge Hogwarts, if he wanted to find twenty glass beads, ordinary people couldn't find them in a day.

"Professor, can you tell me what you know about Professor Slughorn?" Holding the glass beads in his hand, Harry asked expectantly.

Wang Xu is not a person who can't afford to lose, and if he loses, he loses, so he said: "Go back and tell Dumbledore that Professor Slughorn's hidden secret is that he told Voldemort how to make Horcruxes." Voldemort made a total of seven Horcruxes, and it was only possible to kill him if he destroyed them all, otherwise he would be resurrected, go ahead, go and tell Dumbledore, Dumbledore would understand. ”

Harry nodded heavily and ran away with the glass beads.

Wang Xu stood at the door of the Potions classroom, looked at Harry's figure disappearing into the corridor, and whispered, "What a lucky boy!" ”
