That being said.
Although Jiang Yuan could not yet fully utilize the power of the armor robe, he had, in fact, already established dominion over the Chinese Netherworld.
He had become a Pharaoh in terms of status, on par with Pharaoh Khufu!
The day he acquired all his power, Jiang Yuan would surely kick Khufu off his throne.
This world only needed one Pharaoh!
Additionally, as the Ancient King in terms of status.
Jiang Yuan could control the Dark Abyss and command all the Undead under him.
The Dark Abyss always drifted in the main plane, its coordinates elusive, and only Jiang Yuan and the imperial jade seal could pinpoint its location.
So he made a bold move.
He used the imperial jade seal to fix the Dark Abyss within his Netherworld Space!
Currently, his Netherworld Space was on the first layer, where there were only the Three-Eyed Underworld General and Twisted Undead.
But if one entered a deeper layer, it would be the hellish Dark Abyss with an endless supply of Undead!
"I need your help with something," Jiang Yuan said.
"The King only needs to give the command, and I will surely fulfill it for the King! If the King wishes for me to serve him, I will find the most perfect body to possess and serve the King!" Jiu Youhou replied firmly, a hint of slyness in her eyes.
After all, Jiang Yuan did not yet possess the supreme, world-sweeping aura of a true Ancient King, so Jiu Youhou would occasionally say irrelevant things while maintaining proper respect.
Of course, her loyalty was undoubtedly absolute!
"That's not necessary," Jiang Yuan waved his hand, then asked, "I need to completely fill the Netherworld Space, which requires a vast amount of Undead materials. Can you find enough materials for me?"
As one of the Eight Directional Undead Monarchs, Jiu Youhou was an extremely powerful feudal lord among the Undead, so she should possess many Undead materials.
"Is the King intending to transform the Netherworld Space into another Dark Abyss?" Jiu Youhou immediately realized what Jiang Yuan intended to do.
Jiang Yuan nodded: "You could say that. It would be a pity to leave such a vast Netherworld Space empty without filling it."
Jiu Youhou lowered her beautiful eyes, her delicate brows furrowed, and after a moment of thought, she said, "Most of the Undead in China are in the King's Dark Abyss. If all the current Undead materials were utilized... the King's Netherworld Space is so enormous that it could probably fill one-third of the space."
"Only one-third?" Jiang Yuan was a bit surprised.
Although his Netherworld Space was larger than the Dark Abyss, it shouldn't be that the entire China could only fill one-third of it, right?
"Indeed, only one-third. However, the King could instigate an Undead calamity, converting all those humans and demons into Undead materials, which would easily fill your Netherworld Space!"
Jiu Youhou's voice carried no emotion; killing living beings was utterly insignificant to her now.
Jiang Yuan frowned: "No, an Undead calamity is not allowed now."
An Undead calamity could be instigated abroad, but those magic organizations would not sit idly by and watch it happen.
It was very likely to draw out many Forbidden Spellcasterss.
Even the conflict between the Undead Kingdom and the Demon Kingdom would make them covetous, as the Ancient King's identity naturally stood opposed to humanity.
Some people would definitely not give up an opportunity to destroy the Undead Kingdom.
Of particular concern were the Archangels hidden among humans in the Holy City.
Therefore, Jiang Yuan would absolutely not instigate an Undead calamity until he possessed sufficient strength.
Even when Zhan Kong became the Ancient King, he only attacked the Egypt Undead Kingdom after obtaining all the Ancient King's power.
"This..." Jiu Youhou could not think of a better solution.
For the Undead to expand their territory, slaughter was necessary.
The Undead could not reproduce like demons.
It was truly difficult for her, a small specter.
"Never mind, one-third is already a lot." Jiang Yuan no longer pursued filling it completely; this could be done gradually, as he already held an entire Undead Kingdom in his hands.
What's more, one-third of the Undead population already amounted to millions!
"Go prepare, and collect all the Undead materials." Jiang Yuan gave the order, and at the same time, the armor robe on his body faded away.
As long as he needed it, he could make the armor robe reappear with a single thought.
"Yes, my King!" Jiu Youhou's figure flickered, disappearing without a trace.
Jiang Yuan did not leave the Dark Abyss, but instead summoned a Commander-level Undead to use as a punching bag to test the power of his magic.
Magic radiance lit up, and several terrifying spells fell upon the Commander-level Undead, instantly engulfing it.
"Indeed, the power of Level Six magic is a qualitative leap!" Jiang Yuan exclaimed, very satisfied with the enhanced power of his magic.
He could easily kill Commander-level Undead.
After its Death, its soul power rapidly dissipated, forming either a Spirit Essence or a remnant soul based on the final dissipation level.
Seeing this, grey-black Undead Tentacles rose from Jiang Yuan's feet, extracting the Commander-level Undead's soul.
In his hand, the soul quickly transformed into a Spirit Essence.
This was the new Undead secret technique Jiang Yuan had acquired, the Soul Extraction and Spirit Absorption secret technique that Qin Yun had once told him about!
The power of the Soul Extraction and Spirit Absorption secret technique lay in its ability to guarantee a Spirit Essence one hundred percent of the time.
There was no such thing as a remnant soul.
It was precisely because of this that he had such a massive quantity of Spirit Essences, allowing him to strengthen all his magic to Level Six!
How many people in the world could be so extravagant?
Only that small group of people standing at the top of the Mage Pyramid could afford such extravagance!
A massive quantity of Spirit Essences not only meant an unprecedented increase in magic power, but also meant endless wealth!
With money, one could buy ninety-nine percent of the world's magic resources!
Even Heavenly Seeds could be purchased.
As for where the Soul Extraction and Spirit Absorption secret technique came from?
Mastering an Undead Kingdom, what's wrong with having powerful Undead secret techniques?
In fact, Jiang Yuan even had Soul Sealing Art and Ghost Devouring Art!
The effect of Soul Sealing Art goes without saying; it could create many powerful vessels.
Magic tools for cultivation, magic equipment worn on the body, etc., could all be created.
These could also sell for a high price.
The other, Ghost Devouring Art.
This secret technique was different from what Jiang Yuan had imagined.
The power of the Ghost Devouring secret technique was undeniable; it could allow the user to become a super Mage comparable to a Supreme Monarch in a short period.
And as long as there was an opportunity, the boundary between Monarch and Emperor was not insurmountable.
Perhaps one couldn't become a legitimate Emperor.
But it was much stronger than a Sub-Emperor level!
However, there was a give and take; the side effects of the Ghost Devouring secret technique were also very significant.
Once the Ghost Devouring secret technique was performed, one could no longer stop, otherwise, they would be backlashed by the Undead within their body.
Even if one continued to devour, the secret technique user would gradually lose human emotions, and their thoughts would increasingly resemble those of the Undead.
One could imagine how terrifying such a scene would be: a group of such secret technique users, initially revered as ghost-exterminating masters, later all turning into Undead puppets who only knew slaughter.
