Strongest Demigod System

A deep shiver traveled down Azrael's spine as he read this, and he quickly looked away from it. There was something deeply disturbing about the way the mantra had read itself into his mind. It was almost like a curse that was meant to be heard only in the darkest of places.

Azrael pulled out the sword from the sheath a little just so he could see the blade, and the black metal stared back at him. There was no reflection on the blade's surface even when Azrael stared right at it, but the edge of the blade promised a very sharp cut if Azrael dared to touch it.

Ding! Ding! Ding! Ding!

Azrael's attention was suddenly drawn toward the system tabs, and he frowned as he saw multiple notifications coming all at the same time. They were layering themselves over one another, and Azrael had to rearrange them mentally before he was capable of reading the first one.

…

[New Message: Congratulations!]

Congratulations, the user has struck a deal with the personification of death, Thanatos. This deal grants the user multiple benefits in exchange for the souls of all demigods and creatures that the user will slay in the future. Does the user wish to look through the various benefits? Yes/No.

…

Azrael took in a silent breath as he read through this. He already knew that he was going to be killing other demigods, but it was still a little sobering to see it displayed so obviously on a screen. It made it feel more real. Azrael chose yes in the system tab, and the system brought up another message.

…

[The user has received the Artifact [Oathkeeper: Cursed Blade of the Death God] from Thanatos]

Oathkeeper: A cursed artifact forged in the depths of the Underworld and bestowed upon the user by Thanatos himself as a pact with death. With every enemy slain, the blade drinks deep into their soul, offering them as a sacrifice made by the user towards Thanatos.

Effects of [Oathkeeper]:

-> Silence of Death: The user's feet will make no sound, and the user gains a two-rank reduction in [Aggro [Presence]] upon equipping the blade.

-> Inevitability of Death: The blade will always return to the user no matter how far away it is.

-> Immortality of Death: The user's soul has been claimed by death, therefore, unless the user suffers an attack that takes his life immediately, the user will not die from any wound or external curse.

-> Curse of Death: The blade of the underworld is a divine artifact that has shed more blood than any other weapon in existence. The souls of all the violently departed shall never rest in peace, which in turn prevents the wielder of the blade from possessing perfect health. The user is cursed by Necrosis.

…

Necrosis? What the hell was Necrosis!?

Azrael read through all of the messages in that tab, and he was stunned by the effects that the blade gave him! They were extremely impressive, and it would have been amazing if not for the final part of the message that cursed him!

There were still more tabs to be read, but Azrael didn't feel like opening any more of them until he found out what exactly Necrosis was!

Azrael asked the system what it could tell him about Necrosis, and the system answered quickly with a new tab.

…

Necrosis is a curse that was inherited by the user once the user equipped the cursed blade [Oathkeeper]. As the curse of Necrosis progresses, the user slowly gains rot or decay along his body.

In order to delay and reverse the spread of Necrosis, the user needs to feed the Oathkeeper with the souls of demigods according to the conditions set by the user's God Aspect.

Due to the user's relationship with the underworld and death, this is a condition that cannot be cured.

…

Azrael read through the tab quickly as he tried to understand everything about the condition that he had now. And once Azrael saw that the curse was going to spread rot across his body, he put his hand on his face and rubbed it tiredly. This basically meant that Azrael had to continue killing no matter what if he wanted to make sure that the curse didn't spread.

Azrael had already decided that he was going to carry out Thanatos's mission, but the fact that there was now something forcing him into continuing his actions made it more difficult for him to back out. Azrael was in this for the long run, and he was going to have to face whatever the consequences of his decision were in the end!

But Azrael's tiredness didn't last long once he read through the rest of the tab and he saw the term [God Aspect] written boldly there! The system just said that he would have to follow the terms of his God Aspect, right?! Then, didn't that mean he had one? He had a God Aspect!

'Show me the God Aspect!'

Azrael quickly ordered the system to bring up the God Aspect, and the system answered.

[The God Aspect is one of the gifts granted to the user by Thanatos. Would the user like to open the tab showing this gift? Yes/No]

Azrael quickly chose yes in excitement, and he saw another tab come forward.

…

The user has been granted the God Aspect [Soul Eater] by Thanatos.

Soul Eater: This is a God Aspect that allows the user to consume the soul of any demigod that he kills. The soul of the demigod is presented to Thanatos as a sacrifice, and in return, Thanatos will allow the user to consume the God Aspect held within the soul and make it his own.

Conditions:

-> The user can only absorb God Aspects that are of the same rank or higher.

-> A God Aspect absorbed by the user will no longer undergo cultivation and will remain at the rank it was absorbed as.

-> The user cannot absorb God Aspects from any of the Demigods blessed by Thanatos.

…

Current God Aspect Rank: F Rank 

Passive Effects of God Aspect Ranking:

->The user can only use one God Aspect at any given time. In order to use another God Aspect, the user must first deactivate the previously used one.

…

Azrael read through everything in his system tab very quickly! He could feel his heart beating in excitement just from the thought of having a God Aspect, and as he read, Azrael's excitement didn't get any less! In fact, it kept increasing!

He could absorb more God Aspects from other demigods?

Then, doesn't that mean he could have as many God Aspects as he wanted!? Azrael was stunned by what he was seeing on the screen! He knew that Thanatos would give him a strong ability, but wasn't this too broken!? Thanatos was practically telling Azrael that he could have all the power in the world as long as he was willing to kill for it!

Shink!

Azrael felt the blade in his hand thrum in response to his emotions, and he tightened his grip on it. The question of morality came forward to Azrael's mind once more, but Azrael turned that away quickly. If morality was an option, then Azrael wouldn't have taken this blade in the first place.
