In the Daybreak Tower, Zatiel has been sending his golden flames to the spine for days. His Eye of Life and Creation was monitoring the process and arousing the special properties in the flames.
The process had to be done carefully since any damage done to the runes in the Pit Fiend's spine will be irreversible which will weaken it tremendously, and making it lost most of its abilities.
Even with the constant replenishment of his energy pool by the magic tower, Zatiel was growing more and more tired, but he did not stop and continues advancing.
It was at the end of the seventh day when the blue liquid had completely evaporated that the purge of Hell Aura from the spine was over.
The mind corroding power was still present but the foul energy in it has vanished and now you could see thin golden lines running through it.
The paths that were previously containing Hell Aura were now filled with Sun Force. When Zatiel saw these lines he was surprised since this was not supposed to happen.
It was only when he analyzed the spine with the help of the A.I. Chip and the Elder Brain and notice that there was no damage done to the spine due to this change that he relaxed.
He did not start with the refinement immediately since it will take a long time and it will be better if he was in top condition before starting.
However, before he could start resting Dante's voice was heard on his mind.
"Father I have troubling information about aunt Sophia and I require your assistance to decide how to proceed."
Zatiel eyes narrowed when he hears this and signal the boy to continue.
"She asks me to gather and organize all the information about the demons that have entered Beta Heavenly World, more specifically those whose Emperor bloodline has a connection with the soul."
Zatiel face was serious when he hears this information and he understood the source of Dante's concern.
Sophia was looking for a new bloodline among those demons that have entered the Beta Heavenly World and her requirements were especially high.
Emperor bloodlines will be bought from the kingdom thanks to the deal Zatile made with Sirin, but they will mostly be those who belong to the bottom of that classification and could not compare to the ones the Neo-Demon desires.
Trying to capture a Rank 4 demon with an Emperor bloodline is incredibly difficult since they will usually attempt suicide attacks when they saw no chance of escaping.
And that difficulty only increases when their bloodline gave their soul special abilities making restraining their bodies and energies to stop them from killing themselves useless.
She will need to approach it through a different angle and the danger will be very high.
Zatiel remained silent for some time as he was thinking what to do and in the end, his eyes displayed determination.
"Give her all the information that she wants, including the one obtained through the Duke. Tell her that she will need to have a Sun Tadpole in her hand from now on and that tadpole will be connected directly to me."
"As you wish father."
'The universe is full of dangers and I will not always by your side to help you. I hope you know what you are doing' All sorts of emotions were present in Zatiel's eyes but in the next second, they became void before closing themselves.
Zatiel sleeps for two days before he finally felt all of the exhaustion leave his body.
He made a two-meter diameter rune formation on the floor and sat in the center of it before making the Pit Fiend's spine fly to his hand.
Slowly Zatiel consciousness, energy, and life force started to soak the Pit Fiend's spine and you could see how it trembled from time to time as the process advanced.
The technique that Zatiel was going to use was named Inner Fire All Creation Refinement. The principle behind it was to make the item you seek to refine part of your body.
This will allow you to give it form and more importantly, your energy will be able to fill the weapon with more ease. You will be able to draw part of its power and not need to fully activate it to use it.
By nurturing the spine with the power of his soul, body, and energy the compatibility he can reach with it will be much higher and it is essential before the fusion.
The nurturing lasted for several hours before finally, the essence of Zatiel was able to infiltrate it.
Right now Zatiel could move the weapon with his mind but the refinement was far from being over.
The Neo-Demon's eyes were cold before manipulating the spine and making it pierce his back and bury under his skin.
When the spine enters his body, the effect of the mind corrupting force became hundred of times stronger and although it could not break Zatiel' will or twist his ego, it was powerful enough to become a burden in a fight.
Right away the Chaotic-Core started to act, generating a suction force that traped that power inside it, eliminating the flaw that would have affected the prolonged use of the weapon.
Protrusion could be seen in Zatiel's back as the Pit Fiend's spine moved before it finally positions itself above this one own vertebral column and starts circling it.
The pain was intense but the Neo-Demon remained expressionless as he activated the rune formation under his feet that made his entire body glow with a red light.
From the tower, a torrent of golden flames reached over Zatiel and immersed this one, making the red glow stronger and the heat it was producing was astonishing.
Even with the power of his body, Zatiel feels like he was being burned alive but that did not stop him or affected his concentration.
'Brutal with other and even more brutal with yourself!.' The eyes of the Neo-Demon glowed with ruthlessness and he increased the power of the flames bathing him, and by doing so he made the red light more powerful, reaching the level where it starts burning his skin.
Zatiel could feel how the Pit Fiend's spine was starting to embrace his vertebral column, forming a sort of exoskeleton around it.
As the heat increased the bones from the two spines began to fuse. It was only now that the true pain began and Zatiel feels his back being shattered over and over again and flames incinerating his spinal cord.
He did not let the pain distract him from his goal and guided the fusion. Slowly the protrusion on his back was diminishing as the fusion advanced.
That unbearable torture remained for more than ten hours before finally the process was over and Zatiel's body crumbles on the floor.
The Neo-Demon had fourth-degree burn injuries all over his body. His golden flames and the ones from the tower started to heal him and you could see how they regenerated skin, bones, tendons, and muscles with impressive speed.
Zatiel remains on the floor without moving until he was completely healed.
Although the damage seems very severe it did not reach his inner organs or affected his consciousness so after the golden flames heal his wounds, he was like new.
He focuses on his palm and after a second, movements could be felt from his back before a sword that was formed by a segmented series of bones raises from his hand.
It was one and a half meters long, filled with engraved runes that glowed with blue light.
Zatiel was very happy with the sword and without wasting time, he gets out from the tower and raises into the sky before starting to perform all types of sword strikes with it.
The destructive power of those attacks was much greater than the one Zatiel could perform with his previous sword but that was only the beginning.
The Sun Force and Abyssal Aura of the Neo-Demon filled the spine and some of the runes in it were activated.
Even after using his two energy pools and having refined and fused it with his body, Zatiel was able to activate only 1% of the runes in the sword.
But that 1% made blue flames fill the sword and they consumed all the oxygen around the Neo-Demon instantly.
Arcs of flames were now released with his attacks and he was sure they will be able to ravage any Rank 2 life form that came in contact with them.
And that was not all, as Zatiel activated the second ability that the sword could activate, this one extends for one hundred meters in less than a second, and it continues growing in all directions.
It was not moving in a straight line. The sword could make all sorts of twists and turn according to Zatiel will.
This scene calls the attention of many people and they saw in the sky a man grabbing what it seems to be the tail of a giant flaming demonic snake.
This was a scene that they will remember when tales of this sword are heard in the future.
