Hogwarts Staff Maker

"If I weren't your roommate, I would really think that you were studying something weird!" Ron said in the dormitory with a frown.

Liu Sen put the live bat in his hand back into the cage, took off his gloves, picked up a pen and started writing and drawing. "Don't worry, I won't let you see me when I'm researching weird things!"

Ron knew, of course, that the other party was joking, so he matched his joke with a 'terrified' expression and said, "Let's go! Grab a good seat and cheer for Harry!"

Liu Sen agreed and left the dormitory together. There was a Quidditch match today, Gryffindor vs. Slytherin.

After arriving at the stands, Liu Sen distributed the snacks in his bag to Ginny and others, then took out a pair of special-shaped glasses and started adjusting them.

They are called glasses, but they don't have transparent lenses, and you can't see anything through them. Wearing them will completely block your vision.

What’s more special is that there is a pair of huge ears on both sides of the glasses, and they can automatically adjust the direction like animal ears.

This is Liu Sen’s latest developed ‘sonar glasses’!

In order to deal with the snake monster that kills anyone who looks at it, Liu Sen pondered and borrowed the "echo imaging" ability of bats to create this magic prop that does not rely on visual perception of the environment.

As long as I don't look at you, your eyes can't hurt me! I get the image by listening to the sound, what can you do to me?

When the glasses start working, they will emit ultrasonic waves that are inaudible to the human ear. After the sound waves hit the object, the returning sound waves are captured and processed by the big ears on the glasses, and then turned into pictures and input into the wearer's mind!

With the blessing of magic, the glasses present a very clear picture to the wearer. Except that they can only "see" black and white, there is no difference from what the eyes see! The range is wide and the delay is low. It is quite "unscientific!" But it is very magical!

Liu Sen also added a magic detection function to it. If there is a magic fluctuation anywhere, the glasses will give a prompt immediately.

On the field, the Slytherin team used brutal tactics to steal the ball from Gryffindor, and Marcus Flint dribbled the ball and hit the opponent, earning 10 points.

At this moment, a thin figure suddenly appeared in Liu Sen's glasses, with tennis ball-shaped eyes, a pointed nose, and big ears... a house-elf!

Taking off the glasses and looking over, I saw the figure hiding under the stands diagonally opposite. If it weren't for the fluctuation of magic power just now, it would be difficult to find his trace!

"Dobby?" Liu Sen frowned and muttered to himself, why is he here?

Liu Sen borrowed Ron's telescope and looked over. He saw Dobby looking up and staring at Harry on the field. After hesitating for a long time, he snapped his fingers.

Soon Liu Sen knew what the other party had done, because a Bludger suddenly went crazy, staring at Harry and chasing him relentlessly!

Harry used his flexibility to his advantage, moving in a zigzag pattern and spinning in circles, and dodged several attacks.

The Bludger is fast but not flexible enough, and often a sharp turn by Harry will cause the Bludger to lose its direction.

A blessing in disguise was that while Harry was dodging the Bludger, he suddenly discovered the Golden Snitch.

Soon after, Malfoy also found the target. The two of them snatched the Golden Snitch one after the other, followed by the crazy Bludger.

After a thrilling chase, Harry narrowly caught the Golden Snitch, but was hit on the arm by the Bludger at the last moment.

The Bludger carried Dobby's magic power, which accidentally interfered with the protective suit, and the airbag that was supposed to be deployed in advance lost its function! Harry's arm was instantly broken!

It was not until Harry was about to fall off the broom that the protective suit reacted and wrapped him tightly.

After the protective suit offset the impact of the fall and was slowly recovered, everyone could see the golden ball in his hand.

Lee Jordan's commentary suddenly sounded, "Harry Potter caught the Golden Snitch! Gryffindor wins!"

Amid the cheers of the crowd, Harry struggled to sit up from the ground. He felt severe pain in his broken arm whenever he moved it.

At the same time, Liu Sen quickly went around to where Dobby was.

"Certainly!"

A swift bolt of lightning struck Dobby, instantly freezing the house-elf.

Dobby tried hard to turn his eyes, which were as big as tennis balls, and when he saw Liu Sen, he instantly showed a look of horror.

"Dobby, are you taking this a bit too far?"

Liu Sen said angrily, "I know you want to protect Harry, but what you are doing is really stupid. You might accidentally kill him!"

Seeing that the other party was rolling his eyes anxiously, as if he wanted to say something, Liu Sen controlled his magic power and untied the restrictions on Dobby's mouth.

"Dobby must ensure Harry Potter's safety! Dobby is doing this to keep the great Harry Potter away from Hogwarts!"

The other person sniffed and said in horror: "Something terrible is about to happen in Hogwarts!"

Liu Sen chuckled: "Oh, I know, isn't it just a secret room? There will be basilisks and other things in it. You underestimate us too much, it's just a basilisk, it's not enough for me to chop it with one sword!"

Suddenly, there were cries of surprise from the little wizards and dull 'bang bang' sounds from the arena.

Liu Sen frowned and looked over, only to see Harry rolling around on the ground in a panic on the field where the game had already ended, trying to avoid the crazy Bludger.

"Why isn't it over yet?"

Dobby hurriedly said: "Let me go! Let me stop the magic!"

But Liu Sen didn't give him a chance. He quickly took out the Thunder Wand and swung it to cast a "lighting spell"!

This time's lighting technique is different from the previous ones. It is a new technique that Liu Sen has learned based on the newly learned black magic.

To put it simply, this illumination technique can launch a beam of mini lightning lightsaber!

I saw a streak of light flying out in an instant, automatically correcting its direction in mid-air and accurately hitting the Bludger. At the moment it penetrated the sphere, a dazzling white light flashed - it exploded!

Liu Sen nodded, very satisfied with the new lighting technique he had learned.

"Let's call it... Illumination Technique - Laser Gun Mode!"

He smiled and said, "Dobby, look, Harry is very safe with me, don't do anything tricky in the future..."

"Huh? Where did it go?"

When I looked back, I saw that Dobby had actually untied the magic and ran away!

Liu Sen sighed helplessly. The elves' magic was very unique and could be used flexibly with just a snap of fingers.

Judging from Dobby's performance of magic in the past few times, the elves' magic is a self-contained system that can not only interfere with wizards' magic, but also ignore the restrictions of Hogwarts and perform Apparition!

"I'll find a house-elf if I have the chance! I'll study their magic!"

Liu Sen was in a bad mood because he failed to 'dissuade' Dobby, but he quickly came to his senses.

If I remember correctly, Gilderoy Lockhart is going to use his "half-full bottle" technique to harm the world again...
