Na Yufeng also admired Xiao Ling's inference and visitation ability, and gave Xiao Ling advice with tens of millions of years of cultivation experience, explaining how to use these laws to find the possibility of finding a way out of trouble.

"When you reach the cultivation of the Lord God, you will be able to realize that the energy attack in this mixtape is not terrifying, and if you can't get rid of the shackles of the power of the rules, don't try to get out of here. ”

"Little Brother Xiao Ling, although you are a genius, even such a chaotic and complex energy attack makes you think of the method of frequency change to classify it, and you have also found out the law. This method is really wonderful, brother, I have seen this kind of energy classification for the first time in tens of millions of years, and it is really new! Now our confusion is, what use can we use if we master this law?"

"After everyone's energy is out, the law of decay is unexpectedly different. This is the first time I've heard of this kind of individual difference, and it's really new. ”

"The frequency of the energy we shoot is different, and we can't produce energy that is consistent with the rhythm of the energy changes you detect. How do you use the law, and does it do anything to get out of trouble?"

"Your cultivation and perception in this way is in line with the monk's behavior. But it would be naïve for you to think that you would be able to get out of here by mastering the laws of ordinary energy changes!"

"To get out of here, you must understand the power constraints of the rules, and those energy attacks will not be of much use no matter how well they are mastered. ”

After carefully analyzing these wonderful laws mastered by Xiao Ling, Yu Feng came up with the result of useless four words.

Although in the analysis of the wind, Xiao Ling's methods were useless, Xiao Ling himself did not think so.

Of course, only he knows best in his heart the rules that Xiao Ling found out by himself, how to use them, and how they work.

These days, Xiao Ling has studied the Broken Love Flute in his hand from time to time, and constantly penetrated the True Yuan to stimulate the Broken Love Flute to send out a unique wave attack into the mixtape. There were also seven special flakes that appeared in Xiao Ling's hands, which were the flakes in the folding sticks that Xiao Ling accidentally obtained.

In Xiao Ling's feelings, the thin slices in the folding stick are similar to the material in the broken love flute, and they should be the same kind of thing.

The unique substance in the Broken Love Flute and these seven flakes, no one has really recognized what they are, even Yu Feng was at a loss when he saw these two things. This flake is a wonderful tool for sound attack, but it is not unique in itself. For a person like Yufeng, who doesn't understand the rhythm, such flakes are just useless scraps.

At this time, the Broken Love Flute and the Seven Flakes were certainly not waste products in Xiao Ling's heart, and Xiao Ling had already noticed that the sound attack energy emitted with the help of these two flakes was consistent with the frequency fluctuation laws of two of the twelve energies he had explored.

The energy of each person in this world is different, but the frequency of energy emitted through the same instrument depends on the device itself and not on the person using the tool, and the frequency change of the same tool is the same.

It is no simple coincidence that the energy attacks emitted by these two flakes coincide with two variations of the twelve energies.

Xiao Ling chose one direction with the two thin slices in his hand, and combined the special energy changes against the mixing tape, and transmitted the energy attacks emitted by the two flakes into it, and soon Xiao Ling discovered some patterns. When there is only one type of flake attack, it will be sent farther than if it is issued irregularly. When two types of sound attacks appear in that direction according to their corresponding frequencies, they travel several times farther than a single one. According to this conjecture, if three of the same frequency are emitted according to the law of ability transmission, they must be able to travel farther, but what if there are four and twelve?

The sound of the dream piano can be transmitted from the netherworld world, and there must be someone in the netherworld who has mastered the law of sound transmission in the mixtape.

Xiao Ling kept imagining, and constantly deduced various possibilities from the experiment.

After coming to the rule that it takes twelve energy changes to successfully transmit sound in the mixtape, Xiao Ling began to make sound tools in this world of extreme material scarcity.

It is impossible to condense the thin skin in the flute and the thin slice in the folding stick, but it is possible to test the other ten frequencies of the attack flakes.

Xiao Ling used the matter of the Yang World to suppress a fast sheet, and then refined it, kneading divine power into it, and then used the divine power to stimulate the sound attack energy, constantly experimenting with the frequency changes of energy changes transmitted from these thin sheets.

After 200,000 experiments, Xiao Ling got a thin slice that conformed to one of the 12 energy change frequency laws; after 150,000 experiments, Xiao Ling got the fourth fastest qualified flamer; after 100,000 experiments, Xiao Ling got the fifth fastest flamella; after 50,000 experiments, Xiao Ling got the sixth flam, and after 10,000 experiments, Xiao Ling got the tenth, eleventh, and twelfth fast flakes.

Xiao Ling's self-made sound attack slices only have similar energy change laws, and the intensity of the sound attack energy that can be emitted is not comparable to that of the Broken Love Flute and the Seven Flakes. Fortunately, all Xiao Ling needs is a replacement.

While obtaining these flakes, Xiao Ling was also constantly experimenting with the sound and attack energy into the mixtape. Those voices move forward in the energy of the sonic attack. By the time Xiao Ling obtained the combination of six thin slices, the distance of the sound in the mixtape had already exceeded the sensing range of Xiao Ling's divine sense.

The seven-tone combination, the eight-tone combination, and even the last twelve-tone combination, Xiao Ling could feel that the degree of weakening of those sounds and sound attack energy in the transmission was getting less and less, and when he got the twelve-tone combination, within the range that Xiao Ling could sense, the sound was not reduced in the slightest, and the sound attack energy was not weakened in the slightest.

The twelve tones were combined, and Xiao Ling's twelve doppelgangers each controlled one tone, and the complete flute sound was transmitted inward in one direction of the mixing tape with the unique sound transmission law.

Xiao Ling made twelve flutes from the thin slices he developed, and the materials used by Xiao Ling to transform the material of the yang world with the divine power in his body.

The twelve flutes were in the hands of Xiao Ling's twelve doppelgangers, and one by one complete songs were transmitted into the mixtape.

These tunes came out, and there was a reaction. Xiao Ling's flute was replied to by the sound of the piano.

Xiao Ling sent out three tunes on this day, and the piano sound came with the same three tunes.

Xiao Ling couldn't see how far the mixtape was, and he couldn't calculate how long it would take for the flute to reach the netherworld.

It's just that the outgoing music has been replied, which has proved that the flute has reached the underworld world. This news is very good news for Lu Ping and Xiao Ling.

Xiao Ling kept sending out the doubts in his heart through the music, and all of them were answered by the qinyin.

With a song, Xiao Ling learned a little about the situation in the yin world.

Liang Jing is not the only one who controls the sound of the piano in the yin world, the people there are also trapped, and there is no way to get out of the trap.

Xiao Ling tried to understand Liang Jing's method of transmitting sound several times, but he failed to get an effective expression, and the communication method of the song was very limited, and there were many differences between the repertoire of Xiao Ling and Liang Jing, and there were many obstacles between the communication.

When Xiao Ling heard the sound of silence coming from the piano, he guessed that the person who played the sound was Xin Ning. Xiao Ling once used his doppelganger to save Xin Ning, and the two had a special sense of induction, and it was much smoother to communicate with Song than with Liang Jing. Xiao Ling also learned some information about the Yang Side World through a duet with Xin Ning.

While transmitting sound with the laws he mastered, Xiao Ling was also conducting other experiments. He studied the twelve energies with his heart, and soon discovered that they were extremely well connected. The twelve energies actually exist in pairs, and when the two opposing energies meet, they disappear silently.
