"No need to wait as the preparations are done." Du'an stated as he appeared before them.
Seeing that everything was ready, all of them head towards the place where the evolution will take place. Adrian thought that it would be a secret underground chamber, but it was actually the audience hall of the undead citadel. The entire audience hall was redecorated with magic circles and barriers to make sure that Charon is controlled should it break free from Adrian's control.
All of the Undead Knights under the Undead King Arthur were also present in the audience hall. The Doom Knight Cruz, the twins Noire and Blanche, the Ghoul Asura Valar, the Astral Wraith Du'an and the newly added Undead Angel Babel are all present along with the Undead King Arthur. The strongest of all of the undead were present to see the evolution of Charon.
"I am suddenly getting nervous because all of the undead knights under the undead king are present. Why are they present?" Adrian stated.
"We just wanted to make sure that nothing goes past us. This is not just for you but for us as well." The Undead King Arthur stated.
"Please summon Charon in the magic circle in the middle. I have prepared it to make sure that it can hold him in place. I also enchanted it so that all the energy that Charon will be used for evolution will not leak so the chances of success are higher." Du'an stated.
"I shall trust you then. Please let everything be fine." Adrian stated as he summoned Charon at the middle of the magic circle.
Adrian then took out the Dreadful Heart and gave it to Charon to hold. Charon took the item that his master entrusted him and started to assimilate it under Adrian's command. Charon needed to place the Dreadful Heart inside of his body which means it will become the heart in its body.
Charon's robe in the chest area started to vanish and the rib cages of the undead is exposed. One could see that Charon does not have a heart in the rib cage which means it had no heart all this time. The reason for the heart item requirement is actually to fill the undead with a heart.
Charon's rib cage opened up as the Dreadful Heart is placed in the void inside it. The Dreadful Heart that was no longer beating started to beat as if it became alive once more. The moment that the Dreadful Heart started to beat; the dread energy started to flood Charon's body.
[Your soulbound, Charon, has started to assimilate the Dreadful Heart.]
Adrian saw the notification and waited for the assimilation to be completed. He could see the powerful energy spreading to all parts of Charon at a fast rate. It seems that the absorption of fear and dread with the blessing of the God Charon made Charon easily integrate the Dreadful Heart.
[You soulbound, Charon, has fully assimilated the Dreadful Heart.]
[Your soulbound, Charon, has completed all requirement for an evolution. Do you wish to have your soulbound evolve?]
"Yes. Start the evolution process." Adrian stated as all of the undead knights went into position.
As soon as Adrian accepted the evolution process, a powerful energy suddenly exploded in the undead citadel. Charon released a fearsome energy wave that alerted a lot of beings in the central continent. The shockwave even alerted some of the angels that are in search of powerful undead.
"It seems that the thing that we predicted has come true. Even the magic circles could barely stop the energy leak. If it was not stopped then it might have reached the other continents." Du'an stated.
"Cruz, Valar, and Babel, prepare for the defense." The Undead King Arthur stated.
"As you will, my liege!" The three replied as they left the audience hall.
A large black cloud gathered on top of the undead citadel, but it was not an ordinary cloud. It was a cloud that had the energy of fear and dread gathered from the central continent. It was energy materialized which means Charon's evolution is not something to take lightly.
The fear and dread energy that materialized suddenly came down on the undead citadel as Charon absorbed it all into its body as a powerful swirl of energy gathered in the audience hall. All the remaining people in the audience hall could feel the powerful energy suppressing them. Even the Undead King Arthur is amazed as he could only block the suppression because he was a higher entity.
[The wish of the soulbound, Charon, has reached the will of the world.]
[Your soulbound, Charon, has been granted the boon of growing to a higher entity as it has exceeded the requirements.]
[Your soulbound, Charon, is evolving to the Supreme Dread Overlord.]
"The restraints of the magic circle cannot hold on! Champion Equinox, what shall we do?" Du'an asked as he looked at Adrian, but the latter has already entered a trance like state.

"The answer you need is already within you."
The words of the God Charon echoed in Adrian's head as he went inside his subconscious as he could feel the link between him, and Charon started to weaken. Adrian wanted to go to Charon's soul chamber, but he was actually sent to his inner most world instead. The inner world where the strange tree is present.
"To think that I would see you here. I thought you have already forgotten this place, but it seems our soul is pleading for you to descend here." A voice that sounded like Adrian stated.
Adrian turned to the source of the voice only to find a being that looked like him. Adrian knew exactly what it was, and it was his last inner demon. The Noblesse inner demon that carries the last fragment of ultimate power hidden inside of him.
"So, the God Charon was actually hinting at the tree inside my inner world that even I do not know of. Just like how this tree held Sirius down, I must do the same for Charon." Adrian stated as his Noblesse inner demon smiled.
