Vampire Overlord System in the Apocalypse

-----

Noah looked into the Lifeblood Jewel he was going to upgrade now. He was going to use a bunch of System Points once more and upgrade it to gain even more power on it and quite possibly not only enhance the power of the already existing abilities, but also gain some brand new abilities on it to give him a greater advantage on battle… there was also the necessity of upgrading it to Great Deity-Grade so the Lifeblood Jewel's Summons can also be enhanced to that Realm…

…

[Lifeblood Jewel: Vicious Vampiric Blood Necrolord Summoner (God-Grade)] (500/500) (Upgraded!): The combined and awakened power of Blood Servants and Necromancy has formed this powerful and deplorable Lifeblood Jewel, containing great necrotic power within it and the ability to awaken life within death.

…

Noah looked into the Abilities on it and recalled how useful all of them were, the ability to generate zones where Undead would grow stronger, the ability to make them regenerate faster, and even one with the power to let them constantly fuse together and assimilate one another so they can continue evolving and growing stronger… this Lifeblood Jewel was the one that create the frightening army of Blood Undead that Noah employed on his wars the most after all!

With this power… Noah can command many Undead and level entire armies. And after he had assimilated and defeated two gigantic Armies of Divine Beast, the power of such Undead had skyrocketed even more as there were now within their Ranks a lot of Divine Draconic Beasts corpses that were turned into Undead and merged over and over again with the other already existing Undead.

Noah had tried using the Divine Beasts on his divine realm to add to the Undead army, but he discovered that it was impossible to transform them into Blood Undead for some reason, and would simply stay dead whenever they actually died, which was very annoying to him.

Due to this, getting external Divine Draconic Beasts to add to his army was the best! And to boot, they were constantly increasing as he made them march all over the continent as of now, which was one of the things that also triggered the Dragon Gods to finally decide to act against him.

Of course, Noah didn't know the details about such a thing yet… However, as of now, he only cared about upgrading this Lifeblood Jewel to its next power level and bring forth an even more terrifying army of Undead to his enemies. The terror in their faces is always a delightful thing to see for Noah.

Noah walked back to the Lifeblood Jewel Forgery and threw the glowing red jewel into it, which had the shape of a skull, a drop of blood, and even bat-like wings atop it… he looked into it and quickly saw the aura it emanated, pure blood within it…

Now, he had to use enough System Points and quickly upgrade it to acquire even more unprecedented power than before. He was already beginning to imagine what abilities might emerge although he also imagined something such as Summons could emerge, perhaps…

"Hmm… I wonder what could emerge…" he wondered.

Noah's eyes squinted as he looked into the forgery, a system window emerged after he inserted his will into it desiring to "upgrade" his lifeblood jewel.

Ding!

[Do you desire to exchange 1.500.000 System Points to upgrade your Lifeblood Jewel to Great God-Realm?]

<Yes> <No>

Noah quickly pressed "yes" right away, as the points flowed out of his Soul and reached the floating Lifeblood Jewel, the enhancement began to happen right away, but something else was there, just like in the previous time, he had also accumulated a large amount of materials! Indeed, the entire room was filled with divine materials he had gotten from his divine realm, infusing them all into the lifeblood jewel, fusing with it and nourishing it with even more power.

It was as if he were making something through Item Combination in games, where one crafted items by merely merging them together, this thing was similar, he was simply infusing materials into the lifeblood jewel so it could be crafted into an even greater form… this felt as if Noah was truly in control of the entire situation. Constantly pouring more materials into the entire thing, a glowing sea of darkness and blood emerged around the entire jewel, making it grow bigger and more majestic…

FLASH!

The entire Lifeblood Jewel emanated a strong Vampiric and Bloody Aura, shaped into a massive bat-like specter, the bat-like specter roared angrily, rushing towards Noah, and then infusing itself into his soul, the same way it happened with the draconic lifeblood jewel.

"ROAR!"

TRUUMM!!!

Noah gritted his teeth as his eyes glowed with bright crimson-red light, he took over the powerful spectral bat phantom head-on, and quickly decided to calm down and relax, slowly controlling the enormous quantities of power coming from the jewel.

SPARK!

Then, out of nowhere, red lightning began to come out of it, as massive amount of wailing souls which were concentrated inside of it emerged, roaring and crying angrily at him, but Noah quickly forced them to go back and upgrade themselves with it.

CLASH! CLASH! CLASH!

The sparks of red lightning continued for several minutes as the millions of souls merged back together into the jewel… Noah had never seen such a relentless jewel before, upgrading them to great deity-grade was really a challenge by itself!

However, after a few seconds, it was finally over…
