Capítulo 436: Origin Law Comprehension.

"Sound!!!"

Once Sebastian became exposed to this resonating sound from afar, he became exposed to the mysteries of sound magic and sound itself in ways that he never thought of or even expected.

His mind which seemed to be in a half-asleep state previously seemed to be stimulated as it finally became conscious enough to observe things in detail.

Sebastian seemed to hear voices speaking into his ear.

"…Sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid".

"…Sound is the reception of waves and their perception by the brain".

"…Sound is the sensation perceived by the sense of hearing".

"…Sound is a mechanical radiant energy that is transmitted by longitudinal pressure waves in a material medium such as air and is the objective cause of hearing".

"…Sound magic is the manipulation of sound waves".
