Of course, the reason why the Beit Empire has such a strict control system is that the virtual space is another important reason.

Virtual space was conceived during the First Empire of Beit, and after artificial intelligence began to be put into practical use, people found that in order to truly liberate the productivity of artificial intelligence, it was necessary to give them a wider space to stretch.

One of the things that the Bait people have been doing during the Second Republic is to spread out the virtual space.

Now, many people are already thinking about whether the Beit people need to transform into virtual beings to meet the development trend.

But these are not things that Wang Qian needs to think about, he has to do the homework of the last "History of the Development of Music and Rhythm" first.

Also riding in a hovercar, Wang Qian returned to his real-world residence from Gapari Park. Wang's father and Wang's mother are not there, but the meals made by Lele using housekeeping tools are not bad, and Wang Qian is not worried about eating.

"Lele, I decided to complete my music homework in the real world, but we shouldn't have a relevant body stabilizer at home, you go to the Ministry of Education to apply for one." Wang Qian said to Lele.

"Why bother, music creation like this, which involves ultrasound and infrasound, is obviously the most convenient virtual space." Lele was a little helpless and scratched his paws.

"Music is very metaphysical, and the first people who expanded their music creation into the field of ultrasound and infrasound did not use virtual space.

Even later imitators mostly say that it is not the same as using it in the virtual space.

The most important point is that our section of "History of the Development of Rhythm" will focus on the musical development of the late First Empire of Beit, in this case, it is better to restore the scene as much as possible. Wang Qian gave a reason.

"Okay, okay, I'll apply for a set of equipment and come back, and you'll mess around before then." Lele projected a screen in front of him, and casually waved his paws to indicate that he had applied.

"And what are you going to do?" Lele looked up and asked.

"In the last class, Mr. Chen said that many people have written very good music after trying to create ultrasound or infrasound, and I want to try this path.

Actually, I really like Li Siming's "Weng Bell Song", the feeling of being smooth, upward, and as if everything is getting better is awesome. Wang Gan also snapped his fingers and twisted the "Weng Bell Song" released by Lele for a while.

After chatting a few words, the things that Lele applied for had already entered the basement of Wang Qian's house along the logistics track.

For the houses built on the ground in reality, the underground logistics system is generally used, and the engine he renovated when Wang Qian went on the engine maintenance last time was also sent through the underground logistics system.

Moving out of the basement, one large and one small, Wang Qian returned to his study.

Open the two boxes, the small box is the helmet audio receiver and sounder, responsible for allowing Wang Qian to hear ultrasound and infrasound.

The large box is the physical condition maintenance equipment, which is responsible for ensuring Wang Qian's physical health when receiving ultrasound infrasound.

Connecting the two pieces of teaching equipment to the standard auxiliary compartment on the side of the study, Wang Qian lay in. It's not about entering the virtual space.

Even if there are those two pieces of equipment, Wang Qian can't wear them directly, and such equipment must be connected to an external auxiliary warehouse.

If it is a device that has a greater impact on the human body, such an auxiliary compartment is not enough, and it is necessary to go to the life support cabin.

But in fact, there is no problem with the virtual space with the greatest impact, and you only need to ensure the security of your own perimeter, which is basically the simplest guarantee.

In this case, thanks to the development of science and technology, the virtual space technology was also gradually lowered from the external equipment of the auxiliary compartment of the life-support cabin to the built-in receiver.

"Now the body takes over, and the nervous system isolation is complete." Not long after Wang Qian lay down in the auxiliary warehouse, Lele began to operate in an orderly manner.

As a burst of perception disappeared and reappeared, Wang Qian's nervous system was connected to the simulation device.

"Now for the sonic blocking. …… Shielding is complete. After this step is completed, Wang Qian can no longer hear any external sounds, and if he wants to hear it, he needs Lele's approval.

"Now start the normal sonic frequency test, from 19HZ to 20000HZ ascending playback." As Lele's voice ended, a low voice sounded, and it slowly became higher and higher, until Wang Qian couldn't hear it.

"How do you feel, if there is any discomfort, you should report it in time." Lele asked.

"Very well, please continue. Let's start with infrasound."

This kind of discomfort mostly refers to psychological discomfort, physical discomfort does not exist, but psychological discomfort is difficult to say.

"NOW START 10HZ TO 19HZ SOUND WAVE PLAYBACK." A lower-frequency sound wave sounded in Wang Gan's ears, which was first simply played up and down, and then slowly evolved into some simple tunes.

After listening like this for about ten minutes, the sound waves switched to a lower frequency. If you can still find a hint of familiarity in the 10HZ-19 HZ just now.

NOW'S 0HZ-10HZ IS MUCH MORE ABRUPT, LIKE A CURVE SUDDENLY APPEARING IN A BUNCH OF STRAIGHT LINES.

After more than half an hour of familiarization, Wang Qian barely found some rhythm.

After another ten minutes, the sound returned to its normal frequency.

"Now start 20000HZ-100000HZ sound wave playback." Lele continued to operate.

The voice came to Wang Gan's ears again, and this time it made Wang Gan feel even more at a loss, the feeling of hearing it but not being able to define it made Wang Gan feel confused.

It wasn't until later that the frequency began to change, and Wang Qian barely found something useful in the ultrasound.

IN THIS WAY, THE ULTRASOUND CONTINUED UNTIL 10000000HZ AND ENDED.

"Now to start the appreciation of super auditory music, it is recommended to start with "The Rhythm of the Galaxy". Lele suggested.

"Let's get started." Wang Qian nodded, at least he felt a nod signal and received feedback.

Tossed into the evening like this, Wang Gan's early experience finally ended.

"Now begins the return of neurological trusteeship." Another burst of sensation disappeared, and Wang Qian regained his sense of his body, but it was actually the same as when he was entrusted just now.

"Now start the return of body control, please be careful not to do drastic movements." Wang Qian blinked and raised his hand slightly.

"Now we start stripping the teaching aids. …… The stripping is complete. Begin to get out of the auxiliary bin. …… Disengagement is complete. ”

There was a tremble, and Wang Qian felt that the force acting on him no longer controlled him.

Pushing open the auxiliary warehouse door and sitting up, Wang Qianchang breathed a sigh of relief.

"Psychological rating is recommended." Lele continues to perform its duties.

After another half an hour of psychological testing, Lele officially said that the experience was over.

"How's it going, how is Lele doing?" It was the first time for Lele to deal with such a big matter, and he asked with some excitement.

"Not bad. More reliable than I expected. Wang Qian praised.

Lele was so happy that she chased her tail in a circle, she knew that she was really good this time, and Wang Qian was also very enthusiastic about agreeing.

"Then it's time for music creation, and hopefully this experience will allow me to make good music. I have a few good inspirations. ”

"Okay, okay, I'll help."
