In the blink of an eye, nearly three months have passed.

Ye Cheng's cultivation progressed slowly, and he was only promoted to the second level of the day after tomorrow.

At this rate, it is impossible for him to reach the great perfection of the day after tomorrow without three or five years.

Actually, this speed is not slow.

He hadn't even taken an elixir.

It only relies on the blood detoxification method once a day.

He had experienced the divine speed of the inner breath level, and he was very dissatisfied with the current cultivation speed.

For these three months, he spent most of his time in the Moxiang Garden of King Jing's Mansion.

It is a place where all kinds of texts are stored.

There are a lot of kinds of books, but they are all biased towards literary ideology, what Confucianism, Buddhism, Taoism, Legalism... It's basically not compatible with martial arts.

Although this world is respected for martial arts, there are still quite a lot of other schools.

There are no restrictions on entering the Moxiang Garden.

Ye Cheng saw some information about the subconscious from some classics such as Confucianism, Buddhism and Taoism, but unfortunately most of them were explanatory theories, obscure, and there was no specific way to apply them.

At first, Ye Cheng looked very hard and was incomprehensible.

But as he studied it repeatedly, he also had some understanding.

"I wonder if hypnosis can affect the subconscious?"

Ye Cheng put down the book in his hand and thought about it.

In the previous life, there was a specialized discipline on the earth, called psychology, and some high-level psychologists would be exposed to hypnosis.

Some powerful hypnotists can use hypnotism to induce people's subconscious.

It is said that there are lullabies that may put people into a deep sleep and touch the subconscious.

Ye Cheng also had a strong interest in hypnosis.

So, I had some knowledge about the hypnosis side of things.

It is said that there are five types of brain waves that are often used by psychologists to treat patients.

Among them, the alpha wave is called the frequency bridge between the conscious and the subconscious.

"If there had been those brainwave music from previous lives, maybe the problem would have been much easier."

Ye Cheng sighed.

Suddenly, he was stunned for a moment, thinking of something, and excitement flashed in his eyes.

Because he finally came up with a solution.

Even if he didn't have the brainwave music of his previous life, he could have simulated it?

He doesn't need real brainwave music, just alpha waves.

Alpha waves range in frequency from eight to twelve hertz.

That's eight to twelve vibrations per second.

In music, this is a very low frequency, and the fundamental tone of the music is mostly above 60 Hz.

Like a piano, only the bass is between 80 and 100 hertz, and the sense of presence often reaches the level of several thousand hertz.

And the pipa, guqin, erhu and the like are all similar.

It's not difficult to create eight to twelve frequency sound waves, it's the persistence that is difficult.

At least he doesn't have the ability, so he can only find a professional musician.

In King Jing's Mansion, a group of professional musicians were raised.

It's just that how to get the musician to help you with this has to be planned carefully.

When leaving Moxiangyuan, Ye Chengqiao met a person.

It was a young man, dressed in loose white, and his temperament looked indifferent and elegant.

Ye Cheng recognized it at a glance, this person was a musician in King Jing's Mansion.

I just don't know the specific name.

In this world, the status of musicians is not high.

When Ye Cheng walked out, the young musician hurriedly took the initiative to avoid it and stood aside.

Ye Cheng wore a eunuch costume embroidered with eagle pattern in green.

Only the guard eunuchs above the seventh rank are qualified to wear them.

Gray, Tsing, Green, Blue, Red, Purple... This belongs to the different grades of clothing of eunuchs.

Ye Cheng stopped, looked at the young musician, and asked, "What's your name?" ”

"Father-in-law, villain Lin Yu."

The young musician hurriedly said in a respectful voice.

He is a musician, even in the face of the gray-clothed guard eunuch, he will be very polite.

"What instrument are you good at?"

Ye Cheng asked curiously.

"The villain can play the lyre."

Musician Lin Yu said.

"Master Lin, come with me, I have something to ask you."

Ye Cheng thought for a while and said.

Now that you've met a musician, it's time to ask.

"Yes, father-in-law."

Lin Yu was uneasy in his heart, but he didn't dare to refuse.

A green-clothed guard eunuch, if he really wants to embarrass him, he really can't resist.

The status of musicians is too low.

Ye Cheng took this Lin Yu back to his residence.

"You don't have to be nervous, I just have questions about music theory."

Ye Cheng saw Lin Yu's demeanor and said comfortingly.

"Father-in-law, please say, the villain must know everything."

Lin Yu hurriedly said.

Then, Ye Cheng made things simple.

Lin Yu pondered for a moment and said, "Father-in-law, its practical lyre can be done, but the music played like that will probably be very ugly." ”

The human auditory system has a certain adaptation range to the frequency of sound.

Too high or too low a frequency is not enough.

Although in this world, there is no concept of frequency, as an expert in the field of music, musician Lin Yu is naturally extremely proficient.

He came from a family of musicians, and he began to get into music at a young age, and his talent in this area is also extremely high.

"If you can do it, if you have time, you can come and play it for me, and I will pay you accordingly."

Ye Cheng nodded and said.

"Father-in-law, this is not necessary, anyway, the villain has time, why don't the villain go and bring the Qixuanqin over now and play it for your father-in-law?"

Lin Yu immediately said.

"That's for the best."

Ye Cheng smiled and said.

If it really works, I can't say that I have to trouble this musician very often.

Wait for Lin Yu to bring the Qixuanqin here.

Ye Cheng watched him adjust the piano from the sidelines.

It can be seen that this musician cherishes his Qixuanqin very much, and when tuning the piano, he is extremely careful in his movements.

It didn't take long for Lin Yu to tune the piano.

"Father-in-law, the villain has already tuned the piano."

"Master Lin, you can play whatever you want at the frequency I said."

Ye Cheng said.

"Okay, father-in-law."

Lin Yu nodded hurriedly.

Then he sat down, his slender fingers caressing the strings.

Ye Cheng thought that such a low-frequency play should be very ugly.

But in his ears, he felt a wonderful sense of relief, as if under the sound of the piano, his brain suddenly relaxed.

He closed his eyes, adjusted his mental consciousness, and with the help of the sound of the piano, put himself into a meditative state.

This state of meditation is mentioned in the texts of Confucianism, Buddhism, and Taoism.

Unconsciously, he seemed to enter a wonderful state, seeing a new self in his body.

Suddenly, Ye Cheng broke away from his meditative state.

He felt so relieved that he had slept well.

However, he was so real that he had sensed his subconscious before.

The human spiritual consciousness is divided into two parts, one is the surface consciousness, that is, the part of the mind in the waking state.

The second part is the subconscious.

If consciousness is compared to an iceberg, apparent consciousness is only the tip of the iceberg.

It is precisely because the apparent consciousness is too weak that there will be a limit to cultivation, and the cultivation limit that the apparent consciousness can reach is the entry to the innate realm.

If you want to go further, you have to mobilize a stronger spiritual consciousness, the so-called subconscious.

"If my apparent consciousness communicates to the subconscious state and uses the blood dissolving secret method to cultivate, will the subconscious mind also be mobilized?"

Ye Cheng's heart moved, and his eyes flashed with essence.

"Father-in-law..."

Suddenly, Lin Yu spoke cautiously on the side.

He had been playing for a long time, until his fingers were cramping, and he had to stop.

"Master Lin, I worked hard for you just now."

Ye Cheng said with a smile.

But he hesitated in his heart.

It is impossible for him to use the Blood Solving Secret Method to cultivate in front of Lin Yu, although this person is not familiar with martial arts, it is difficult to guarantee that it will not be leaked out.

This is his secret, and it must not be divulged.

"Father-in-law, don't work hard, wait for the villain to rest for a while, and then you can play again."

Lin Yu hurriedly said.

"Don't worry, Master Lin, you've worked hard today, just go back first, and I'll look for you next time."

Ye Cheng got up and said.

Then he took out a silver ingot, and with a wave of his hand, it landed firmly on the table, not moving.

"Father-in-law, I really don't need to..."

Lin Yu hurriedly stood up, not daring to take the silver ingot at all.

"Master Lin, I will have to work hard for you in the future, this is a hard fee, you can accept it."

Ye Cheng chuckled.

"Thank you, father-in-law."

When Lin Yu heard this, he had no choice but to accept it.

It's just that he can't figure it out, how could this father-in-law like such low-frequency music?

But he didn't dare to ask more, maybe this father-in-law was particularly interested?

When Lin Yu left, Ye Cheng said casually, "Master Lin, try not to talk about this matter." ”

"The villain understands."

Lin Yu bowed slightly, and then walked out with the Qixuanqin in his arms.

Ye Cheng looked at Lin Yu's back as he left, his eyes flashing with excitement.

I didn't expect that the great problem that had stumped countless innate martial artists in the Qianguo Kingdom was so simple that I found a way.

Of course, this is not his credit, but only the knowledge that he has mastered on Earth in his previous life.

Sure enough, science represents the primary productive force.

Even in this world where martial arts are respected, it can also play an important role.
