He also knows the God of Death God's ultimate move!?
Zesshi Zetsumei looked back at Ainz after hearing Kael's explanation, her expression instantly becoming serious.
This was absolutely terrifying!
Although both of them had the ability to use [Death's End], the opponent had methods to resist this ultimate technique, but she was powerless against it.
Not only that, [Death's End] itself was an enhancement skill, which required an instant-death magic spell to be effective. The moment she performed this move, she had to activate the eighth-tier magic [Death] loaded into the [Charon's Guidance], and its destructive power was limited to a single target.
However, Ainz was a powerful Magic Chanter, and it was highly likely that he had an instant-death magic with an area-of-effect that targeted many enemies, which would make his battlefield destructive power far exceed hers.
The thought of Ainz releasing such an attack while fighting against the Theocracy's forces sent a shiver down Zesshi Zetsumei's spine.
This person... he might be the Demon God that the Theocracy absolutely cannot handle!
"Step back, you're not his opponent."
A hand gently rested on her shoulder, and in a daze, Zesshi Zetsumei turned to find Kael standing beside her.
Even when facing such a terrifying enemy, there was no panic on this man's face; instead, a calm and faint smile graced his lips. Although his eyes weren't focused on her, Zesshi Zetsumei's heart strangely felt at ease.
Yes, the Theocracy doesn't have to face the Great Underground Tomb of Nazarick alone now. With such a powerful ally, what do we have to fear?
Speaking of which, this man has defeated Ainz Ooal Gown several times before, just how strong is he?
Hmm... he must be stronger than me.
Her heterochromatic black and white eyes flickered slightly, and Zesshi Zetsumei took a step back, guided by the faint pressure on her shoulder. "Then I'll leave it to you, please be careful."
Hmm?
A gentle voice with a hint of a smile reached his ears, and Kael turned around with some surprise. He saw an unusual glint in Zesshi Zetsumei's eyes, and while her smile seemed normal, it gave off an unsettling feeling.
"Damn it! What kind of expression is that from this black-and-white loli? It's a bit creepy."
"Uh... don't worry, we can handle this guy."
After a perfunctory reply, Kael no longer paid attention to Zesshi Zetsumei's strange behavior, his gaze locking back onto Ainz. "So, are you ready to die?"
After going through the battle with Leinas and Zesshi Zetsumei, even if Ainz's HP hadn't dropped much, his MP consumption must have been significant.
He glanced at Ainz's ten fingers; one of them was not wearing a ring, presumably because he had removed the guild ring, which was of utmost importance to the Great Underground Tomb of Nazarick, before this.
Teleportation magic was forbidden between the various tiers of Nazarick and inside and outside the Great Tomb. Without a convenient escape method, unless a Guardian used the effect of the guild ring for a quick support, it wouldn't be difficult for Kael to eliminate the current Ainz.
However, Ainz appeared indifferent to this. He just let out two noncommittal laughs, slowly spread his hands, and said, "As you wish, but I'm not the type to sit still and wait for death!"
"[Maximize Magic · Reality Slash]!"
A pitch-black energy blade swept out with extremely fast speed, striking Kael without a surprise.
A thin layer of shimmering blue energy on his body, shattered into light spots with a bang, and the magical blade capable of cutting through space also vanished without a trace.
Zesshi Zetsumei, standing behind Kael, only felt her vision blur, and a six-winged angel holding a holy cross appeared before her, with a faint prayer-like sound emanating from it.
[Devotion Archangel], it had a special skill that granted the protected target one immunity to an enemy's magic.
"A dying struggle."
Kael sneered dismissively, slowly raising his right hand. [The Ultimate Magic Tome] shimmered into existence, a sealing magic circle appeared at Ainz's feet, and golden chains instantly wrapped around the Undead's entire body.
On the other side, Leinas also summoned his [Light Unicorn] and activated his special [Holy Beast Knight] skills, charging and trampling towards Ainz.
...
Fifteen minutes later, as Leinas's spear, imbued with divine power, thrust down, Ainz's skeletal body shattered and scattered.
One of the rings that had always been on the Undead's finger emitted an unusual light, wrapping the scattered bones along with all of his magical equipment, and instantly teleported it to the depths of the Great Underground Tomb of Nazarick.
[High-Tier Item Appraisal]!
A magical short staff that contained eighth-tier healing magic, completely garbage!
Kael bent down to pick up the only remaining item from the ground. After appraising it with appraisal magic, he couldn't help but click his tongue. The effect of the [Ring of Resurrection · Ultra Rare], in addition to the transfer resurrection, also minimized the drop penalty. It was practically impossible for Ainz's divine-tier Magic Chanters equipment to be dropped, so getting a magical short staff from his backpack was already considered good.
"Here."
With a casual flick, the magical short staff arced through the air and was steadily caught by Zesshi Zetsumei. Although she didn't know why Kael was throwing the spoils of war to her, Zesshi Zetsumei smoothly placed the item into her personal magic pouch.
"Thank you for your generosity, Your Excellency. What shall we do next?"
"Of course, we're getting out first!"
Kael put [The Ultimate Magic Tome] back into his backpack, raised his arms high, and stretched. "This Great Underground Tomb has ten tiers. We don't know how many traps and mechanisms await us deeper inside. With just the three of us, even if we could reach the end, we probably wouldn't have much fighting power left."
"There's no need to rush. Since we've confirmed this is the enemy's nest, they can't escape. Once our army is trained, we'll return and destroy this place."
Upon hearing this, Zesshi Zetsumei placed her hand on her chest and bowed. "As you wish."
Subsequently, the three of them returned the way they came, and before long, they had completely left Nazarick.
Meanwhile, in the Tenth-Tier Throne Hall of the Great Tomb, a flash of light vanished, and a skeleton in a black scholar's robe landed steadily on the carpet in front of the royal stairs.
The next second, the skeleton performed a surprising action.
Clatter!
Kneeling on one knee, the skeleton's face shifted, eventually forming a smooth face like a raw egg, with no other features visible except for three circular holes representing eyes and a mouth.
"Great Supreme Being, I have returned."
The bizarre creature respectfully bowed to the master seated on the throne.
Although he had transformed into a black robe, the skeleton's head, hands, and position on the throne all indicated his identity—Ainz Ooal Gown.
"You have worked hard, rise."
Ainz raised a hand to the servant at the foot of the royal stairs, signaling him to stand.
The creature capable of impersonating Ainz and not being easily discovered by the enemy was naturally the Great Tomb's NPC he had personally created—Pandora's Actor.
Although protected by the [Ring of Resurrection · Ultra Rare], his intention to place himself in danger had been unanimously opposed by all the NPCs. Pandora's Actor's participation in the battle was already a result of a compromise between him and the Guardians.
"Pandora's Actor, now tell us the combat intelligence you personally experienced!"
