In the Demon Suppression Division, the Iron-Cutting Sword Technique is perfected

Deep underground, in the center of the underground palace, there is an empty martial arts field.

Gu Cheng sat cross-legged on the faded futon, and with a thought, he opened the system panel.

To be fair, his aptitude for understanding cannot be said to be shocking, but it can be said to be mediocre.

Fortunately, compared with refining qi and refining the body, he does have a good talent in refining the spirit.

Coupled with the experience of practicing the first volume of "Heavenly Sound Cultivation Technique", he is full of confidence in practicing the second volume.

"Alas, I hope I can get it right this time..."

Gu Cheng took a deep breath, calmed his mind, and poured his life into "Heavenly Sound Cultivation Technique".

On the panel, the number representing the remaining lifespan decreased rapidly...

[First year: You start practicing "Heavenly Sound Cultivation Technique".

This set of exercises is in the same vein as the first volume of exercises you practiced before. With a solid foundation, you can practice it like a fish in water and make rapid progress. ]

[Year 7: The innate realm's soul-refining method is infinitely mysterious and far beyond what you have experienced before.

Although you have good aptitude for soul-refining, you are too obsessed with past experience, which has trapped you and caused you to reach a bottleneck in your cultivation. ]

"I knew it..."

Gu Cheng's face was dark, and there was no ripple in his heart.

He had long been accustomed to such things. With his poor understanding, it would be a problem if he had not encountered a bottleneck.

So he took out the demon core of the Bai family fox demon without hesitation, swallowed it in one gulp, and at the same time infused his lifespan to accelerate the refining.

With the help of a large amount of lifespan, the demon core of the innate realm demon was quickly refined and turned into extremely pure energy that merged into his body.

...

[Year 357: You completely refined and analyzed the demon core of the innate fox demon.

The majestic demon power, like a furnace, tempered every inch of your flesh and blood, every wisp of your divine thoughts.

Under the tempering of the evil spirit of the demon, your physical strength and spiritual consciousness have been slightly improved.

In addition, many insights about spiritual cultivation and body skills have emerged in your mind.

Many problems that have troubled you have been solved at this moment, and you seem to have touched the door to a new world. 】

[Year 391: You successfully broke through the bottleneck of the mortal realm, and suddenly felt that your spiritual consciousness had reached a new level.

At the same time, after the precipitation of these long years, you have accumulated a lot and successfully comprehended an innate magical power. 】

[You comprehended the magical power: Innate·Phantom Sound]

[Spiritual cultivation: Innate first level]

Boom——

Gu Cheng only felt a loud noise in his mind, as if some shackles were broken in an instant, his consciousness became clearer than ever, and his perception was also raised to a new level.

The light in his dark eyes surged, like two sharp swords out of their sheaths, revealing their sharpness!

"Is this the feeling of entering the innate realm after refining the spirit?"

Gu Cheng silently felt the changes in his mind, as if he had experienced a spiritual baptism. His thoughts were clearer than ever before, and he felt as if he was in the clouds, feeling indescribably comfortable.

What surprised him even more was that as his cultivation of refining the spirit broke through the innate realm, he actually awakened another innate magical power.

[Innate·Illusionary Sound: Your mind strength is becoming more and more solid, and your resistance to illusions has been significantly improved.

At the same time, your voice has magic power, and you can use language or music to cast illusions to confuse the enemy. Those with low strength will be completely hypnotized by you and let you do whatever you want. 】

"Uh... Why is the description of this magical power like a book?"

Gu Cheng looked strange, and some of the "hypnosis" masterpieces he had appreciated involuntarily emerged in his mind... His mood became more and more subtle.

Then he took a deep breath, threw those messy thoughts behind his head, and continued to look at the panel.

On the other side, the kryptonian cultivation on the panel is still going on...

[363rd year: After breaking through the bottleneck of soul refining, you finally opened the door to a higher realm and officially entered the innate realm!

If the cultivation method of the first volume of Tianyin Nurturing Mind Technique is to listen to beautiful music.

Then the cultivation method of this second volume is no longer passive listening, but actively playing the sound of nature, stirring the heartstrings of others with the rhythm, and tempering one's own mind with the spiritual resonance of the audience.

Your piano skills are naturally beyond doubt, but if you want to play this heavenly sound, who should you play for, and who can be your audience? 】

"This..."

Gu Cheng's brows were twisted into a knot, and he couldn't help but fall into deep thought.

The innate realm's skills are all demanding.

Compared with "Canglong Bailian" requiring "True Dragon Orb" and "Blood Sword Sutra" requiring "fellow practitioner's blood".

This "Heavenly Sound Nurturing Mind Technique" only requires "audience" to practice, which is already a very simple requirement.

However, with Gu Cheng's life-threatening cultivation method, where can he find listeners to "resonate with his spirit"??

"Wait..."

Gu Cheng suddenly had an idea.

"This audience, it seems that they didn't say that it must be a 'living person'?"

He thought, and ten years of life were burned out in an instant, and the charming and enchanting figure of the Blood Lady appeared in his mind again.

This soul remnant was a rare drop in Changle County. I thought it had been drained of its value, but now it seems that it may still be useful...

[Year 368: You gently plucked the strings of the zither, and the remnant soul of the Blood Lady became your audience.

The melodious sound of the zither echoed, and she looked at you infatuatedly, as if the whole world was left with only your handsome face and moving melody.

Under this extreme spiritual resonance, the strength of your mind has increased slightly! 】

"It works!"

Gu Cheng grinned, with excitement in his eyes.

In this way, things will be much simpler.

He no longer hesitated, and continued to infuse his life force, activating all the soul remnants that had exploded from the previous demon slaying, no matter how big or small, strong or weak!

The Blood Lady of the Blood Knife Sect, the Wolf Demon King of the Black Wind Mountain, Feng Sanshi of the Evil King Pavilion, the Water Snake Demon of Shuiyunze... and Elder Huang, who had "joined" this big family the latest.

This group of demons and evil cultivators gathered together, like a corpse party, listening to the music played by the person who had ended their lives with their own hands.

If you think about it carefully, this scene is quite a joke in hell.

[Chapter 383: You began to practice the Heavenly Sound Nurturing Mind Technique with these remnant souls as your audience.

As the saying goes, it's easy to get a lot of money, but it's hard to find a soulmate.

These remnant souls have already been filled with your favorability, and regard you as a life confidant. At the same time, in the remnant soul state, they are more easily affected by music.

Therefore, under their spiritual resonance, your cultivation speed has improved rapidly! ]

[Year 413: Blood Lady was bewitched by the sound of the zither and danced involuntarily, her enchanting figure swaying in the dimness.

Feng Sanshi was even more intoxicated by the sound, tears welling up in his eyes, as if he had seen the most moving scene in the world. ]

[Your Heavenly Sound Cultivation Technique has broken through the realm of ‘minor success’]

[Year 456: Your zither sound is more and more mysterious, weaving a hazy illusion.

The wolf demon king was affected by the illusion, dancing like a dog; the water snake demon was also fascinated by the illusion, twisting his waist to his heart’s content, and being deeply trapped in it. ]

[Your Heavenly Sound Cultivation Technique has broken through the realm of ‘mastery’]

[Year 528: Your zither sound is like crying and complaining, and strong spiritual fluctuations spread with the zither sound.

The remaining souls of the two Xiantian masters, Li Yunhe and Huang Tianxing, seemed to have experienced a spiritual baptism in your piano music. They hugged each other and cried, repenting for their past sins. ]

[Your Tianyin Nurturing Mind Technique has broken through the realm of ‘Great Success’]

[Year 638: Under the spiritual resonance of these remaining souls, the strength of your mind has made a qualitative leap, as if breaking through some kind of shackles.

At the end of the song, all the remaining souls woke up from their dreams. They all saluted you and wished you great success! ]

[Xiantian·Tianyin Nurturing Mind Technique: Perfection]

[Spiritual Cultivation: Xiantian Ninth Layer]

[Remaining Lifespan: 3,666 Years]
