As the maker of the signal receiver, William and skillfully operated the instrument in his hand, finding out how far he was from Arthur Weasley.

He looked up and looked around, and when he looked past the black sedan speeding down the road, he saw Arthur Weasley, right across from him, next to the red phone booth 50 meters away.

At this time, Arthur was holding the shoebox given to him by William in one hand, and the doorknob of the phone booth in the other hand, and then turned his head to look at the crowd around him, then opened the door and walked into the phone booth, picked up the microphone and played with a few metal phone buttons.

Under William's gaze, Arthur inside the phone booth fell down as if he were on an elevator. It didn't take him a few seconds for his figure to disappear, and the phone booth turned back into a free booth waiting for the next person who needed to use the phone.

"Is this one of the entrances to the Ministry of Magic?"

After seeing Arthur enter the Ministry of Magic in the elevator inside the phone booth, William's eyes twinkled, and he thought for a moment. Then, when the sidewalk light is green, quickly cross the street and come to the phone booth.

At this point, the arrow on the receiver in his hand had disappeared, which meant that he had lost contact with the remote-controlled car in Arthur's hand.

It is unknown whether the signal generator inside the remote-controlled car is interfered with by the magic spell inside the Ministry of Magic and cannot be used properly, or if the band emitted by the signal generator is blocked by the barrier.

But... William had thought of this and was not discouraged by the disappearance of the signal.

He looked up and chose a more secluded alley. Entering the alley, he glanced around warily, then pulled out a device from his backpack that was larger than the signal receiver in his hand.

The device was swarthy and about the size of an Oxford dictionary. But there is a groove in the very center.

Taking advantage of the fact that there was no one around, William embedded the receiver in his hand into this groove.

Then he operated the signal receiver and connected the instrument below, and began to debug different bands, wanting to receive different bands of radio waves from the remote-controlled car.

The interior of the small remote-controlled car allowed William to install four types of transmitters: ultra-long-wave, long-wave, medium-wave, and short-wave.

However, due to space constraints, he was unable to increase the transmission efficiency of the transmitted wireless signal.

A signal amplifier was created to amplify the faint signals captured, so that the signal receiver could capture the signals of different frequencies emitted by the remote-controlled car.

"Can't you? None of the four wireless signals inside the car were received. How can I tell if there's something wrong with the machine, or if the signal is blocked by the Ministry of Magic enchantment?

Could it be that the only way to locate the specific location of the Ministry of Magic is to make a magic transmitter from Hextech..."

Seeing that the signal receiver kept showing "no signal", William frowned, and a look of chagrin appeared on his face.

This result, to put it mildly, is that William failed to find out the specific location of the Ministry of Magic this time. To put it mildly, they didn't receive a signal, which meant that the technology that they, ordinary people, were proud of, was ridiculous in front of wizards.

The Muggle world is developing according to the current technological route, and there will never be a threat to wizards.

"Forget it, at least I've found an entrance to the Ministry of Magic, and I've already met Arthur, so I have more opportunities in the future. When I make a signal generator with Hextech, I'll confirm the location of the Ministry of Magic. ”

William sighed, put the receiver and amplifier in his hand back into his waist backpack, and watched the flow of people on the side, those who are fighting for a better life tomorrow.

He slapped his cheeks vigorously with both hands, forcing himself to cheer himself up.

"If only these people knew that in the world they could not perceive, there was a group of wizards above the world. I must be very flustered. “

William looked at these people with complicated eyes and muttered in a low voice.

Helplessness and despair spread through his heart, leaving a young boy who turned 12 years old in just over 40 days out of place from the rest of the world.

Bang!

Just as William turned to leave the alley and return to the venue to find Hermione, there was a sudden noise behind him.

The strange noise shook William's body, and he subconsciously turned his head towards the sound.

In my field of vision, I saw a pale young man in a black coat, falling on a potholed stone road covered with rain.

He struggled to get up from the ground, ignoring the filthy water, and fell to his knees with his hands on the tiles, gasping for air.

The body twitched irregularly, and it didn't look like a mentally normal person. And the wand in his hand, which was already stained with dirty water, had already identified him.

William looked at the young man who appeared behind him out of thin air, and the corners of his eyes twitched a few times, he never expected that he would actually meet a mentally abnormal wizard here.

'Huh? It's a wizard! Could it be the Aurors? Wrong! He had a wary look on his face, and some madness. Doesn't look like an Auror who just came out of the Ministry of Magic? Could it be! ’

'Is this a fugitive from the Ministry of Magic?' Damn, I need to get out of here! ’

The young wizard's strange behavior and awkward attire had already convinced William that he was a prisoner who had escaped from the Ministry of Magic.

'More is better than less.' I can't get involved in a battle between wizards right now and get their attention! ’

After thinking about it, William immediately pretended not to notice him, quickly turned his head, and walked towards the lively street at the end of the alley as if nothing had happened.

'Don't mind me!' Ignore me! I didn't see you, you didn't see me! ’

One step, two steps, William walked forward at the pace of a normal child, while begging the wizard behind him not to spot him.

... Six steps, seven steps, and when William had already taken the eighth step, the wizard behind him still didn't make any move, and kept kneeling there, but not gasping, but whispering madness.

It seems to have been affected by some kind of spell, making him mentally confused and unable to continue his normal activities.

But this was not William's concern, he noticed that the other party did not pay attention to him, and his heart was happy, and the frequency of the exchange of legs also accelerated a little.

But...

Bang! Bang! Bang!

Just as a smile appeared on William's face, in the space five meters in front of him, three wizards with wands in their hands and serious faces were twisted, and they stared indifferently at the man behind William.

"Erikson, put down your wand. Come back with us and be punished! ”

Among the three wizards, the middle-aged wizard led by him moved the wand in his hand slightly downward to aim at Erikson, who was still kneeling on the ground, and issued a final warning in a cold tone without a trace of emotion.
