Infinite Mana in the Apocalypse

In the grandly floating Frozen Plateau Spiritual Land, a dungeon in the form of a large black monolith was forming in front of all the beasts' eyes.

At the center of the black monolith, the hazy figures of multiple Demon Rulers could be seen. These were the holders of the remaining Seven Deadly Sins skill. The [Sin of L.u.s.t] that had fallen in the form of a skill book into the Imperial Phoenix's hands was currently with Noah, with the Phoenix giving it the moment Noah asked without even asking for the reason why.

The other four remaining skills were still being held by four Demon Rulers that were now going into dungeon bosses for the purpose of extracting their Ultimate Skills without killing them entirely.

"There can only be a single holder of the Seven Deadly Sins abilities anyways, but there exists a new uncharted territory once we succeed on this current endeavor."

The voice of the will of the Demon World rang out in Noah's mind as he watched the completion of the large dungeon which held the origins of four Demon Rulers. He observed the still charging [Sheath Regalia] below the Spiritual Land as he asked,

"The end result will allow for all of them to be combined into a single source?"

A silence arrived briefly before a confident voice rang out deep within the Demon World.

"This was the ultimate form of the Seven Deadly Sins abilities I envisioned. With the help of the other three cores, it should not be a problem to achieve something I only thought would be possible after hundreds of years!"

Noah nodded at this as his figure moved forward and disappeared into the newly made dungeon as he pursued his first goal of a rapid rise in strength after his return to the past.

The process was not hard at all as the Rulers were either in the Phantasmal or Mythical Rank, and with the fact that they were not even resisting, Noah was able to destroy their cores very quickly. Not even a few minutes after he entered, his figure appeared back on top of the Spiritual Land as the dungeon that was just erected began to break apart and disappear.

It faded away to reveal the sorry figures of four Demon Rulers who had their origins injured after being defeated in the dungeon, and they also came to the realization that they had lost the Ultimate Skills they knew all too well for the past hundreds of years.

Noah waved his hands as in front of his sight five red and golden-colored books appeared, four from the Demon Rulers and 1 that he took from the hands of the Imperial Phoenix. The Ultimate Skills that signified the Sins of L.u.s.t, Greed, Sloth, Envy, and Wrath floated peacefully around him before they turned into red streams of lights that entered his body.

He watched the addition of five new Ultimate Skills in his stat panel as the moment they settled, they began seething a deep red color. Noah's figure quickly disappeared from the Spiritual Land as he reappeared deep at the center of the Demon World, just a few meters away from its core.

"Let's do it!"

The will of the Demon World was watching with rapt expectations as immense energy that only it could provide poured towards Noah. It would finally have the chance to watch the ultimate ability that it had only dreamed of come to fruition!

The cheat of escaping death could not easily be given to Noah, but the combination of the Seven Deadly Sins abilities she created could definitely be done to singularly become the epitome of what she imagined as the strongest warrior for the world!

Essence from Noah's homeworld came into play as the feature of [Skill Combination] that would normally only work for two compatible skills was shining a deep hue of blue, contributing to the combination of the completed Seven Deadly Sins abilities.

OOONG!

Noah floated near the core of the Demon World as red light ruptured out of his body, the ultimate skills gradually being fused into something else as his skin began to turn a shade of red, and magnificent golden horns began to appear on either side of his head.

The transformation seemed to show the progression of the combination of the Seven Deadly Sins abilities as glorious black wings also erupted from his back, his figure becoming bulkier and larger as it let off a feeling of oppressive strength that Noah had only seen in a few beings.

Runic golden circles began to be etched into the new body as they formed into an exquisite set of lines throughout his body. The moment they all connected, a resplendent golden-red light erupted out as it signified the arrival of something grand.

"Haha, success!"

The resonant voice of the will of the world erupted out as Noah closed his eyes and reveled in the feeling of strength he currently felt. His eyes opened as they let out a deadly red light, his gaze landing on his stat panel as a new set of words appeared below the list of Ultimate Skills.

<<Absolute Skill :: Absolute Sin>> A skill given to the holder of all the "Seven Deadly Sins" skills. The user is considered to be the Absolute Sin, empowering every sin type skill they hold. It gives access to the skills: [Sin Empowerment], [Harbinger of Sin], [Sin Manipulation], [Sin Syphoning], and [Arch Demon Lord Transformation]

A skill of an entirely different level opened itself in front of his eyes as his gaze focused on the singular abilities of the <<Absolute Sin>> skill.

[Sin Empowerment] :: Any Sin type skill will have strength and cost efficiency increase by one order of magnitude. Each ultimate Sin skill will have one power strengthened even more as well.

[Harbinger of Sin] :: As the Original and Absolute Sin, the user can appoint each sin to a person, making that person a harbinger of that sin, giving them access to the standard version of that ultimate skill. If the harbinger is killed, the ultimate skill will return as a charge to this skill, allowing for a new harbinger to be picked. The user can at any time take back a sin given out.

[Sin Manipulation] :: The user can manipulate the urge of any person, depending on their resistance to such effect, to indulge in any sin or a specific sin.

[Sin Syphoning] :: By indulging in any sin or being within 100 meters of sin being committed, the user's power will temporarily increase. The more varied the sins recently committed, the stronger the boost is.

[Arch Demon Lord Transformation] :: The user can turn into the Arch Demon Lord; this will quadruple the strength and cost efficiency of all Sin and Demon skills. It will also double the efficiency and strength of all other skills used by the user during the transformation.

…

Power!

He felt a tremendous amount of power roll through his body as he understood what this <<Absolute Sin>> entailed!

All of the Seven Deadly Sins skills could be seen as subsets of skills under the <<Absolute Sin>>, holding a few new sets of descriptions as they were made even better. This wasn't to mention the fact that he could use [Harbinger of Sin] to appoint these same Ultimate Skills to 7 people that he chose!

His gaze shone with a resplendent light as he looked forward to testing the power of this new ability, while his mind continued to rapidly figure out possibilities on how to best use his future knowledge to get the most benefits from the next few days.
