In the crowded exhibition hall, Hermione looked at William with dissatisfaction, who had just sent the reporter away. When William returned to her, she crossed her hands on her hips and questioned with a hint of impatience.

"Why do you have to take me with you every time a reporter interviews you?"

"Because genius twins attract more attention than the name of gifted children."

William waved his hand, admitting that he had taken advantage of Hermione. But it's a win-win, except that Hermione is about to go to Hogwarts and won't be able to enjoy the reputation of "genius twins" in the future.

"Huh? How did he end up here? ”

Just as Hermione was about to continue complaining about William, a man in a light gray trench coat stood in the hallway in the center of the exhibition hall, looking around, and it was clear from his expression that he was curious about everything around him.

It's normal if it's a child, but he looks like he's in his thirties and about to be forty.

If it weren't for the fact that the eyes of the people around him were focused on the works of the contestants, they would definitely notice the strange behavior of this middle-aged man.

The weirdest thing is that when someone walks up to him, they don't want to avoid him, as if they don't see his existence.

But when the two collided together, the middle-aged man took the initiative to give way, and at the same time bowed apologetically, looking very gentlemanly.

And the people who walked past continued to ignore his presence. Greet your friends in front of you as if nothing had happened.

"Hermione, you can help me watch first. I had to leave beforehand. ”

William ignored whether Hermione would agree to his request, and under Hermione's disgruntled gaze, he walked over to the middle-aged man, while very covertly taking off the ring on his thumb and putting it in his pocket.

But when he looked up at the middle-aged man with red curly hair again, he found that there was no figure of this person in front of him.

William wondered if he had just left in an instant. But he realized that something was wrong, his eyes had been staring at the glider in the hand of the player next to him, and it was impossible for him to pull out his wand and leave here so quickly.

In a flash of inspiration, William already had a guess in his heart.

So... There is only one truth!

So he hurriedly took out the Hex ring again and put it on his thumb, and the moment he put the ring on, the middle-aged man appeared in his field of vision again.

'Hex's ring, in addition to absorbing magic from the outside world, can also absorb magic from the host. And the moment I put it on my hand, the ring broke the spell that Arthur Weasley had cast on me. That's why I saw him! So is this what is called uncontrollable ability? ’

William understood that this was probably some kind of spell that Arthur Weasley had cast to make the people around him ignore his presence.

And because the ring wants to absorb magic from his body all the time, he unconsciously breaks the spell that affects his spirit, so that he can see Arthur Weasley.

After understanding the reason, William stopped, a little hesitant to continue meeting Arthur. But soon he took another step forward and walked towards Arthur.

"Sir, are you lost?"

"Huh?"

Arthur Weasley had just recovered a few magical items from a dead wizard's home today, and as he was about to return to the Ministry of Magic, he walked in with a curiosity about the Muggle world when he saw what was going on here.

In order not to attract Muggles' attention to him, he cast a covert spell on himself that allowed Muggles to ignore his presence.

But... Now a blonde boy as old as his youngest son, Ron, stood in front of him, asking if he was lost.

Arthur instinctively thought that the blonde boy was talking to the person behind him, so he gave up a position to the side, but he found that there was no one behind him, and the young man's eyes at this time actually followed his movements and continued to watch him.

'The enchantment effect is gone?' ’

Arthur's first reaction was that his spell had disappeared, but when he looked up and saw that no one had noticed him, it meant that his spell had not gone away.

Then why did the young man in front of him notice him?

Arthur wondered, but then William spoke again.

"Sir, I saw you standing here for a long time, and I thought you were lost. Maybe I'm thinking too much, but you're an adult, how can you get lost? It must be because of the work of our children that you have been disappointed, that's why you have this expression. ”

William pretended to be suddenly enlightened and said to himself. Treating Arthur as the kind of professor who wants to see how high the level of technological innovation is in today's teenagers, he is disappointed when he arrives.

"Hehe, little friend. You're wrong, I don't really know what the significance of their inventions is, and my mind is a little confused..."

Arthur was very curious about the William in front of him who could see him, and at first wondered if he was a little wizard from a Muggle family, but then he thought about it, if it was a little wizard, then why did he come here?

The Ministry of Magic strictly forbade wizards to participate in the development of Muggles, and activities such as this could affect the future development of Muggles, and the Ministry of Magic strictly forbade any wizards and young wizards from participating in them.

They feared that wizards would take out magical items that would cause a disturbance at such a crowded event, or affect Muggle technology.

Could it be that he is a little wizard who has not yet entered school? But there was another problem in front of Arthur, who did not feel the powerful magic from William.

What the hell is going on with him?

As a staff member of the Ministry of Magic, he instinctively wanted to figure out why the kid in front of him could see him.

"My name is William Granger. I am the winner of the 34th and 35th Youth Science and Technology Competition, if you want, you can follow me to my booth to see my work. I'm sure you'll be shocked.

By the way, I have hot cocoa and black tea there, so you must be thirsty after being in the showroom for so long, right? ”

William was not afraid that Arthur would find himself suspicious of him. In his memory, the wizarding world of Harry Potter was not so rigorous.

Most wizards only learn magic for the sake of application or research, and do not explore the principles of deep development of these magics at all. Not to mention anomalies that occur all over the world.

William bets that even wizards who work in the Ministry of Magic have many who don't know what obscurity is.

So he wasn't afraid of Arthur getting to the bottom of him. If he really wanted to ask, William had a reason to dispel the suspicions of most wizards.

"Haha, I happen to be a little thirsty too, so let's go to your place."

Out of curiosity as to why William was able to see him, and because he had come to the venue to see the strange objects in the Muggle world.

With William to help him explain, he didn't have to guess what these things were all about.
