Mystic Eyes: My Eyes Steal the Laws of Cultivation Chapter 611: Technique of Sound Qi Resonance (3)

Kyrian narrowed his eyes, understanding the essence. So that’s it. The cultivator needed to use his own weapon as an instrument.

Qi entered the object, the weapon vibrated, and the vibration transformed into sound. But the sound itself did not possess enough power to break the glass.

It was necessary to find a specific frequency, a frequency that corresponded to the internal structure of the plate.

When that happened, the material itself would begin to amplify the vibration. The more it vibrated, the more unstable it would become until it finally shattered.

It was an extremely interesting principle, a practical application of spiritual physics that Kyrian had never considered before.

And also quite difficult, because every cultivator possessed different Qi. Its density, nature, circulation speed, and the way the Qi reacted with the weapon’s material, all of that altered the sound produced. A frequency that worked for one cultivator could be completely useless for another.

Therefore, there was no single answer. It was necessary to understand the technique and then adapt it to one’s own Qi, a process of trial and error that required patience and perception.

Kyrian closed his eyes, breathing slowly as his Qi began to circulate. First, through his meridians, a calm and controlled flow. Then through his arm, the energy moving like water through a channel. Finally, it reached the saber, penetrating the metal.

’Hum...’ A low sound emerged, the blade vibrating with gentle intensity.

Kyrian opened his eyes, watching the plate as the sound struck it. Nothing. Not even a crack, no visible reaction.

Some participants around him had already begun testing their own techniques, and the hall quickly filled with sounds of all kinds.

’Ziiing...’

’ Hum...’

’Clang...’

’Vuuuum...’

Each cultivator produced a different frequency, some high and sharp, others low and deep, some intermittent, others continuous.

Some seemed to experiment randomly, changing frequencies with every attempt. Others tried to follow the instructions exactly, replicating the diagrams with meticulous precision.

Kyrian remained motionless, his eyes fixed on the plate. The sound disappeared, but something had happened, something very small, almost imperceptible. The plate had vibrated. More than that, he had seen the internal structure move, a microscopic part of the material shifting in response to the vibration.

Kyrian’s violet eyes shone, a spark of understanding forming in his mind. So that’s how it is.

He repeated the process, slightly altering the amount of Qi flowing into the saber. The saber vibrated again, emitting a deeper sound.

’Donnn...’ The plate trembled a little more this time, a vibration that traveled across its entire surface.

Kyrian did not move, his gaze becoming even more focused. He noticed a second frequency hidden within the sound, a harmony overlapping the main note. The glass was responding, not merely receiving, but responding, a small vibration returning from the plate.

It was almost inaudible, so subtle that most cultivators would not even notice it. For any ordinary cultivator, perceiving that response would be impossible. But Kyrian could observe even the slightest alteration, his perception capturing every nuance.

He understood the principle completely. I need to find the exact point. It was not simply a matter of increasing the power, if he put in too much Qi, the vibration would lose stability, becoming chaotic and ineffective.

If he used too little, there would not be enough energy to initiate the resonance. Balance was necessary, frequency, amplitude, and density. Everything needed to be perfectly aligned.

Kyrian took a deep breath, his eyes closing again as his Lightning Qi began to circulate through the saber. This time, he did not simply try to make the blade vibrate, he controlled every layer of energy with surgical precision. The internal flow, the speed, the pressure, the direction, and every aspect adjusted to create the perfect vibration.

’Zzzzz...’ The blade emitted a high-pitched, almost shrill sound that seemed to cut through the surrounding air. The plate trembled.

Kyrian observed, his eyes analyzing the response. No. It was not the correct frequency. He adjusted again, decreasing the speed of the Qi flow.

’Zummm...’ The vibration changed, becoming deeper, more resonant. The plate trembled once more, small waves passing across its surface like ripples in a lake.

Kyrian noticed an alteration, an extremely thin line appeared in the internal structure of the plate, a mark that had not been there before. It was not a crack but a line of tension, a point where the material had begun to yield.

His eyes narrowed, the understanding completing itself in his mind.

’I’ve found it. But it still wasn’t enough.’

He repeated the process, adjusting the frequency, adjusting the Qi, and testing again. Each attempt brought him a little closer to the perfect balance, each adjustment refining the vibration until it became purer and more stable.

On the third attempt, the plate vibrated continuously, the sound produced by the saber becoming deeper and denser. It resembled the distant roar of thunder, a sound that seemed to come from far away, carrying the power of storms.

Some nearby participants began looking at Kyrian, their tests interrupted by the unusual vibration emanating from his table. He did not notice, or simply did not care. His attention was completely focused on the plate, his eyes fixed on the tension line that was slowly growing.

Just one more adjustment. He altered the Qi flow, correcting the last imperfection his perception had detected. The vibration became perfectly stable, a continuous wave that seemed to fill the entire surrounding space.

The plate began to tremble, not only its surface but its entire internal structure. The material was responding, every molecule vibrating in unison with the sound.

Kyrian slowly opened his eyes, a violet glow passing through his pupils.

"I completely understand it."

He raised the saber, his movements fluid and precise. The Lightning Qi traveled through the blade, but it did not explode, it was not necessary. Everything was concentrated, compressed, and perfectly controlled, with every particle of energy adjusted for a single purpose.

Kyrian moved his wrist, and the saber vibrated.

’BOOOOOOM...’

The sound produced was not extremely loud, but it was deep, dense, and powerful. Like thunder trapped inside a cave, echoing through centuries of darkness. The sound wave advanced, striking the plate with surgical precision.

For an instant, nothing happened.

Then the plate trembled. Once, twice, three times. The vibrations rapidly increased, each oscillation more intense than the previous one.

’Crack.’

A small crack appeared on the surface, thin as a strand of hair. Kyrian’s eyes remained calm, observing the process with absolute composure.

The crack multiplied, one, two, ten, dozens. Golden lines crossed the glass like lightning trapped within it, a fractal pattern spreading with every passing instant.

Then—

’CRAAAAACK!’
