Hai'er concentrated his astral force and found that the energy that gathered around him was pure and utterly black.
It emitted a evil feeling and caused him to sweat a bit.
The energy suppressed a lot of students who were studying at the time, some of the weaker disciples outright fell at the feel of the ominous energy.
Hai'er looked at his right hand and saw a black, grayish flute that emitted a strong power.
He felt a odd connection to it aswell.
He scrolled through his memories of the book and found in one of the pages it talked about the usage of the dark flute.
"The Demonic Lighting flute is a flute used to amplify dark energies and control music and sound.
In order to use it, you must have a general understanding of Dark Energies and Music Vibrations."
Hai'er was dumbstruck, he read this over and over yet he could not understand what Music Vibrations was.
He looked around the library which was deserted at this point and found a book.
"Music Vibrations and how to use it for offense"
The title was bold and was very prevalent.
Hai'er looked through the book relatively quickly and memorized everything.
"Musical Vibrations is the power to alter sound waves using Astral Force. By channeling your Astral force in your body and emitting it as sound, it can either heal or damage people."
Hai'er recited this and began deciphering how he would practice this technique.
He first tried just blowing on the flute.
No sound came out, nothing happened. It was as if he never did anything at all.
"What a odd flute. Containing such power that cannot be utilized."
He thought aimlessly.
"Aha!"
He had cracked the code.
He began channeling his Astral force and began humming.
Although the reaction was small, the books began shaking gently.
He had reached a general understanding of Music Vibrations.
