Jacob looked at the translucent barrier over the gigantic metal city with scrutiny. He didn't dare to carelessly try to cross it since it would instantly alert everyone, and with how much the Wrath King hated him, he wouldn't waste even a second and come running like a mad dog.
Furthermore, if his guess was right, then this place was under the Spirit Magic Dead King's jurisdiction, and if he were also alert, it would be a problem to hide under the two dead kings' eyes.
Especially the Spirit Magic Dead King, who was known for his powerful spirit magic, and he might not be as helpless as the Aura User like the Wrath King.
'I've already killed over 10,000 unique rank dark beings, and I'm still short on 90,000. This won't be easy; the more I kill, the more alert I make the Dark Faction of the threat I pose, and they might really forget about their integrity and come after me with everything they want.
'Tsk, tsk, the higher the hex core evolves, the more difficult it is for me to find the prey to evolve it. 100,000 Unique Rank Dark Beings could make the entire Life faction tremble, yet I need to kill them by myself.
'But the ghastliest part will come when I need to evolve the hex core to legendary rank. Even if I can kill legendary dark beings, where do I find 100,000 of them?' Jacob felt extremely stiff just thinking about these absurd evolution requirements for the hex core.
Even though the hex magic was overpowered, he needed to pay the equivalent price to wield it as well.
Although he was in Unique Rank Plains, it didn't mean there were only the Unique Rank Beings here. It was just the power capacity of the unique plains was higher than the Common, Rare, or Epic Plains.
The Unique Rank Beings controlled the upper echelon of all major powers, and the powers, like three absolute factions, even had the Three Steps of Legend level experts hidden within their ranks.
That's why now Jacob was in even more hurry to upgrade his epic hex core into a unique rank hex core, so his hex magic could also work on even the legendary rank beings.
Once he wields such power, he won't have anything to worry about, even if the Three Steps of Legend level expert comes after him.
So, he could do nothing but continue with this conquest.
Jacob didn't try using his Eyes of Judge at this moment since this city was simply too large, and he needed more than a second to measure this formation.
Instead, he flew around it to find the door since it would be far more convenient to take advantage of the flaws at the entrance.
Soon enough, he stopped in front of a white metallic door, and huge words were engraved on top of it in Dead Language of Dark Being, 'Spirit Research Island No.87 (Dark Alchemy Branch)'.
Jacob's eyebrows shot up, 'Dark Alchemy?'
He had heard its vague details from Immortika. Apparently, the Dark Alchemy can be used in refining Life Medicines that prolong the living being's lifespan by using the Life Crystals.
Furthermore, only the dark beings could practice this profession while it was a forbidden taboo for living beings.
Jacob never thought he would come in contact with it so soon, but it wasn't so surprising either. He was in the Dead Faction, and since the Dark Alchemy was their bread and butter, he would've come across it sooner or later.
Furthermore, Jacob was very much interested in this Dark Alchemy, especially the Life Medicines. But he was only curious since he already had Nyx's ability to devour others' lifespans and then transfer them to him.
He was only in his early thirties right now, and thousands of years were ahead of him, so he wouldn't take the risk of consuming that life medicine since it had very ghastly side effects on living beings.
'Since this place is a research island for Dark Alchemy, didn't this mean I would find more use of life crystals here? I've already gathered tens of thousands of space rings of dark beings, and once I can open them, I will find even more life crystals in them. It's a pity that Autarch can't open them by possessing other unique rank bodies; his mystic signature is still only epic rank. At the same time, Nyx is clueless about it.
'Anyhow, I have to learn about the secret of life crystals, or they would be nothing but piles of shining crystals.'
Jacob smiled bitterly before he opened his eyes of Judge and closed them. A deep frown appeared on her face, 'This door is not entirely locked with magic runes, but it's a mechanical one imbued with magic runes. This type of lock can be opened by a physical key and a runic key. But this security also proved that whatever is hidden behind this door is worth this kind of security…'
Jacob was now even more determined to enter this place, even if he had to cause a little commotion.
The next moment, Jacob chose to hide not too far away from the door and waved his sleeve. Five black-cloaked and five crimson-cloaked liches appeared.
"Autarch, use them to open that door and then kill anything that crawls out from within." He coldly ordered.
Those ten liches were refined into Autarch's puppets just like the ogres, and they could be stored in space rings as well.
Jacob has been using them to cause commotion and draw away many enemies. Even the Wrath King can't tell the difference between those puppets and dark beings, and he has been fooled many times.
Autarch quickly followed Jacob's orders, and the empty eyes of those liches suddenly lit up in flames, and they sprang toward the metallic door and began to cast spells.
The Lich Race of the Dark Beings has two variants: Black Cloak, which represents the Spirit Lich, which uses Spirit Magic, and Crimson Cloak, which represents the Aura Lich and uses Aura Magic.
Nonetheless, the Lich Race's innate magic talent lies in their Dark Summoning Magic, and Spirit Lich can summon Spirit-
type dark beings while the Aura Lich can summon Aura-type dark beings.
Both have their own benefits and flaws. But if both variants join forces, they would cause mass destruction!
Soon, within the magic circles of the crimson-cloaked liches, magic robes and skeletons holding magic staffs begin to appear, and from the magic circles of the black-cloaked liches, armor skeletons with weapons appear.
At Autarch's behest, they all initiate an all-out attack on the door in front of them!
