After lunch, Harry, Ron, Fred, and George planned to go to the Weasley enclosure on the hill.

There were trees all around it, so they wouldn't be seen by the people in the village below, and they could practice playing Quidditch there, as long as they didn't fly too high.

But they couldn't use real Quidditch balls, and it wouldn't be clear if they were accidentally allowed to fly over Muggle villages.

So they can only toss apples at each other instead of Quidditch balls.

They took turns riding the Light Wheel 2000 contributed by Harry and Rolf, which were much better than the others' broomsticks, and Ron's "shooting star" was often left behind.

Ginny wanted to come along and take a look, after all, her idol was also here, but was sternly rejected by Mrs. Weasley.

She thinks that Ginny must be hit by an apple, could it be that Ginny's full name is Kim Newton Nye Weasley?

Five minutes later, four men climbed up the hill with broomsticks. They had wanted to invite Percy and Rolf to come along, but they said they weren't available.

Until now, Harry had only been able to see Percy while eating.

And Rolf, lying at the Weasley table, studying the wizard radio.

It all started with the diary, where Rolf watched Ginny pitifully try to lift the cauldron filled with 'Lockhart's Useless Series from the Book' and volunteered to help Ginny.

With Ginny's permission, he put the crucible in his suitcase along with the books, but the main purpose was to get the diary.

After returning to the Burrow, Rolf found a deserted grove and secretly released Thomas, hoping to gain new system experience by purifying the Horcruxes.

But after the unicorn evolved the Horcrux, the remaining ball of soul energy left Rolf a little overwhelmed.

He had already made up his mind that he couldn't absorb these unknown soul energies anymore, but he couldn't let them waste it in vain, right?

He suddenly thought of the scene in the movie, where the diary communicates through writing.

Although you were a means of influencing people with Horcruxes, it gave Rolf a lot of inspiration.

Maybe...... I can use this soul energy to build a social media in the wizarding world?

So, during the last period of the Burrow, Rolf fell into the construction of a social network.

It's always hard to create out of thin air, but it's human nature to imitate, so Rolf set his sights on the last old radio in the Weasley family.

Just as Rolf was disassembling the poor radio at the Weasley dining table with the Muggle tools he had Hermione help buy, a sound scared Rolf into the screwdriver in his hand.

"What are you doing?" Mr. Weasley walked over curiously, watching Rolf's movements in some surprise.

"Hello, Uncle Arthur, I just want to know how this radio works. Rolf pretended to be innocent.

The wizarding world is not extremely closed and restless, and it can be seen from the Hogwarts Express that the British wizarding community is gradually embracing Muggle novelty.

But the radio was a big headache for the wizarding world for a while.

Officials at the Ministry of Magic also recognized that they should have some real-time information transmission platforms in addition to newspapers, which are not very time-sensitive information mediums.

They had their sights fixed on the Muggle radio network.

But after Muggles often reported to the radio that they had heard some nonsense about 'wizards', the Ministry knew that this might not work.

So they decided to set up their own radio channel instead of sharing a transmission line with the Muggles.

But they weren't made entirely out of thin air, and the radio knob was turned to "extras" to listen to the Wizard Radio broadcast.

There is also the famous Potter Lookout Station, which uses a magic wand to strike the radio and say the code signal to receive the signal of the broadcast.

All of this inspired Rolf, and he began to think about using the soul energy to simulate signal transmitters or information processing centers to achieve the timely exchange of information.

"Are you interested in these Muggle-derived products too?" said Mr. Weasley, as if he had met a confidant.

"Alright......" Rolf said in a hesitant manner, not knowing how to explain it to Mr. Weasley.

So, Rolf forcibly added a redhead to his social media network construction work.

"What? you want to build your own communication network?" Mr. Weasley's mouth opened in surprise, but he suddenly realized something and quickly shut his mouth.

He continued to whisper, as if he was afraid of being discovered by others: "But if you want to build an information transmission network, you need to manage it by a special person. ”

After hearing this, Rolf fell into deep thought, can he make that group of soul energy simply perform the transmission of information?

He put the radio back in its place, then said goodbye to Mr. Weasley and went back to Bill's room alone.

He took out the diary, and Rolf suddenly remembered the almost useless magic mirror, if the magic mirror was set up as an information relay station, and then the magic mirror was established through a notebook, would this network be built?

He excitedly took out the magic mirror and pushed the ball of soul energy into the magic mirror, only to see that the originally expressionless face suddenly showed a trace of expression fluctuations.

Rolf suddenly realized that he might have done something wrong again, and after this magic mirror gained soul energy, would it be also affected by the emotions inside?

Fortunately, he noticed this problem in advance, so he took out a pencil and prepared to try it by signing a wooden pact with the magic mirror.

As a result, he successfully sensed the connection between himself and the magic mirror, which showed that the originally mechanical magic mirror had really become a living thing.

He casually picked up the Horcrux diary from his side, and then commanded him to put in a little soul energy in the magic mirror.

Rolf scribbled a random passage in his notebook and then asked the Mirror if he had accepted what he had written, to which the Mirror nodded affirmatively.

But there is another question that bothers Rolf, it is impossible for every notebook to pay a little soul energy for the magic mirror to establish a connection, right?

Why didn't there be a means of communication in the wizarding world, nor did any Muggle electronic devices get into Hogwarts, which was a difficult problem to solve.

He decided to throw this problem to Song Ye, who had not been in touch for a long time, and he couldn't solve it himself, so he could only ask for help from his own plug-in.

"What?communication magic? We have the communication stone here, but I've never studied the magic array inside, if you need it, I can help you research it, but this will be an optimization opportunity, right?"

Listening to Song Ye's surprised voice, Rolf breathed a sigh of relief in his heart, he finally didn't need to bother with his own brains, it was easier to exchange it once than to create it out of thin air, right?

In order to make a lot of money, the establishment of this social network is imperative!
