A week later kōga sat once again in his families sealing room.
On the table before him was a extremely large scroll, as tall as him and 2 people wide. Said scroll was fully unrolled onto the table.
The surface of the scroll sat a huge sealing matrix formula, said formula if successfull would turn kōga and anyone else into true chakra monsters.
'Terrifying!' Kōga thought with a shiver.
The sealing formula on the scroll was a true work of art. Anyone who actually understood what the formula drawn did, would probably kneel to kōga and kill him their ancestor!
After mesmerizing everything properly, kōga made his way deeper into the sealing chamber were a sub section was set up for testing large scale fuinjutsu.
Kōga knelt on 1 knee, placing his right hand onto the floor to which he proceeded to inscribe sealing script with nothing but his chakra.
Kōga watched intently, as black fuinjutsu characters wiggled across the entire floor from corner to corner.
"Huff!" Kōga released a breath as he cut the chakra being fed to the inscription. As always at the center of the formula was the clans crest consisting of a swirl.
Kōga proceeded to comb over the entire fuin formula with a fine teeth comb, before nodding in satisfaction after finding everything perfect.
Taking out a blue spherical gem stone which had fuinjutsu etched into its surface with a senbon using the seal etching method.
Kōga placed said Gem stone onto the swirl in the center of the formula.
Stepping back he knelt down by a specific section of the formula, where he proceeded to flood his right index finger with chakra. He then placed that finger onto the section of sealing formula he was standing by before dragging his finger forward in a flick.
Suddenly that section of the sealing array came to life, Glowing softly at first before said glow began to intensify. In a matter of minutes that circular section of fuin script was shining like if a second sun, had appeared.
Kōga squinted before bringing his hands into the tiger seal, activating the rest of the seal array. Kōga watched in awe as the rest of the array lit up in a spreading blue glow, show casing that chakra was in fact being driven into those parts of the sealing array.
A couple seconds later the room was bathed in a bright blue light as the sealing array was fully lit.
Kōga's 'minds eye of the kagura' nearly gave him a splitting headache as the signature from the array spread across the floor, became extremely saturated with chakra.
After waiting for a few seconds kōgan running through another set of hand seals before ending on the ram hand seal.
"Seal intergration technique!" Intoned kōga, causing the swirl at the center of the seal array to rise up off of the floor, before anchoring itself into the center of the gem stone.
Kōga then shifted his hand seal to the snake hand seal. "Compress!" He exclaimed and watched as the entire sealing array shrank in on itself until just the swirl remained visible in the exact center of the stone gem.
As the seal fully embedded itself into the gem, the physically etched on seals came to life.
Kōga breathed a sigh of relief that everything went smoothly, or there would be no land of whirlpool had the seal decided to explode. Kōga wiped the sweat of his brows.
Walking forward kōga reached out to pick up the now brightly glowing gem.
"Hmm." Kōga hummed, tilting his head before speaking. "From now on we'll call you a Perpetual Chakra core or Perpetual Chakra furnace!" He said before enclosing the gem in a pre-prepared sealing cube that erased Chakra signatures completely.
Holding the cube in his hand kōga allowed a grin to break out across his face.
