Supreme Couple In Apocalypse: Undead King & Demonic Queen

The next five days would turn out to be very quiet and uberly efficient for everyone.

Their full focus was on creating skills and increasing their combat prowess.

Unless anyone exhausted enough to require sleep, the practice would go on.

The Virtual Field was a mini-dimension for people to practice with a Rule power.

Rule powers were higher forms of powers that couldn't be negated normally. In a progressive sense, a Rule Power was a branched form of a Concept power at a higher level, but not anyone could comprehend and derive it unless one explored the next level of one's Spirit power and Soul power. Generally, only Reverend-order or higher could create a Rule power.

The Rule power in Heavenly Cloud Town's Virtual Field was [Hyper Recovery Rule], which meant that all people inside would get their injuries recovered at 1000% of their original factors, be it healing skills, or natural self-healing factors related to Bloodlines or Classes.

It was a perfect place for unrestrained sparring sessions and… heaven for Rin and Erix, who were utterly absorbed and focused on creating skills.

They also wanted to manifest and awaken their Domains, but five days were too short for that, so they didn't focus on that.

Erix reached level 3 in his Class due to farming monsters in Pale Hunger Swamp for five days, each level up gave him 4 skill creation attempts since he directly got X rank class.

[Death Reaper]

_Rank: X

_Level: 4 [ 117 / 8000 Royal-order cores. ]

_Death Energy: [ 14,000 / 14,000 ]

_Class Tree:

—> Active skills: Undead Scythe, Dead Doll.

—> Passive skill: Dead Sea.

_Class Domain:

—> Death Domain: Undeveloped.

_Skill creation chances: 16

On the other hand, Rin had more skill-creation attempts than Erix since her class was lower-ranked and easier to level up.

[Razing Blade Serenader]

_Class rank: SSS

_Level: 9 [ 18 / 5000 Royal-order cores ]

_Blade Ki: [10,000 / 10,000 ]

_Class Tree:

—> Active skills: Blade Tune, Ruined Blade Piece.

—> Passive skills: Blade Eater.

_Class Domain:

—> Blade Domain: Undeveloped.

_Skill Creations chances: 28.

The skill creation chances were tons, but it was unwise to use all of them at once, in one sitting.

Moreover, one couldn't have unlimited class skills since a class source was a boon given to people under the influence of Mystic Root and had limited slots in the Class's Skill Tree.

This boon was exclusive to worlds Mystic Root suddenly and brutally pushed into the evolution and path to power.

This was also why people had to kill living beings to gather Mystic Essence at first and then also kill other lifeforms according to 'tasks' to awaken their class.

So, not everyone in Grand Primal Cosmic had a Class because it wasn't required for developed worlds that had accessed Grand Primal Cosmos, unlike Earthlings, who hadn't even explored planets in their Solar System.

Rin and Erix were prime examples of powerhouses not relying on Class powers because they were talented and swiftly improved in the main path of power, much like the rest of the Grand Primal Cosmos.

Lilith was the same, and due to Aria's circumstances regarding her path of power, she was also removed from Mystic Root's influence.

Neither of them had classes. Lilith had one before, but it was removed.

However, it didn't mean class sources were completely useless after exiting Mystic Root's influence. After all, the knowledge of skills they learned and created using Skill Creations chances would remain.

For Rin and Erix, creating class skills using those chances was nothing more than absorbing its benefits and ultimately improving and creating their own skills based on knowledge and inspiration.

The duo had tons of Skill-creations chances that they planned to use on the 5th day to create class skills. But the number of skills one could 'Slot' in their class tree was limited as mentioned.

The higher the grade of the class, the more slots one could have.

S-rank and below had 6 skill slots total.

SS-rank class—7 skill slots.

SSS-rank class—8 skill slots.

X-rank class—10 skill slots.

EX-rank class—2nd domain slot.

Although the number of skills slotting in one's Class Tree was limited due to the class tree only supporting skills according to one's Class Source, the skill-creation attempts could be used to improve/modify their existing skills as well.

Rin and Erix solidified their knowledge regarding Advanced Magic Formations that Tier-5 skills used in the first four days, and created skills by constantly practicing and sparring against each other and other people in the Virtual Field.

They completely overhauled their Combat Arts and created new Skillcrafts.

Naturally, they also derived swift and normal skill-techniques that could be used without using their exotic Combat Arts.

[A/N: I'll gradually reveal their newly created main skills, combat arts, and Skillcrafts by showing them during real battles and situations. Look forward to them :D ]

…

Today was the 5th and final day, but Rin and Erix were still in the Virtual Field with Lilith, Aria, Lily, Maleina, and Amu.

Aria also explosively improved in the past four days, shaping her powers into powerful skills that increased her combat power significantly.

She was more like a Combat-Summoner due to her affinity with the Animus element, using this element's power in tandem with other elements in every single one of her skills.

"Alright, Rin and I are going to enter our daily Limitless Plane session," Erix said. "We'll just sit here instead of returning."

The Virtual Field was a pocket dimension with various floating islands and different biomes.

Erix and the group were on one of the bigger floating islands, which had three different biomes—an icy area, a lavatic area, and the last area raging with exotic winds.

In the center of this island was a spot where all three biomes's influence converged, creating a chaotic place—the place where Erix and others practiced and trained.

"Go ahead. I'll look out for you," Amu said with a nod.

Lilith also created a barrier around Rin and Erix as they sat on a weird black tree's branch with orange and green patterns.

Now that Lilith, Lily, and Aria also had the Way of Unfettered spiritual art, they could enter the Limitless Plane together.

Maleina was already part of another Cosmic Faction but wasn't involved much in that except when she had to get to the next stage of her Spiritual Art.

Unlike the Way of Unfettered, she had a Spiritual Art that boosted her proficiency in Flame powers, giving her exotic flame powers and energy paths, which was also why she was talented in brewing potions and was progressing swiftly recently since Lilith told her to focus on it.

Her Cosmic Faction's branch wasn't even in this Abyss, but she would be able to return to her world or follow Lilith to Earth to join Rin and Erix after ascending to Empyrean-order. The decision was up to her, though she had already decided her option.

…

Rin and Erix spent one and a half hours focusing on gleaning the evolution of their Chaos concept.

They were stuck in 1st realm of the Chaos concept for long enough, and it was time they made a breakthrough. At least, they hoped to make a breakthrough.

The Limitless Plane created things according to their imagination, and so, the duo brought utter chaos to the vast surroundings according to the proficiency of their different applications of the Chaos concept.

The reason they chose to reside in this particular chaotic place in the Virtual Field was also due to them wanting to progress in their Chaos concept in the hope of getting some inspiration while training and sparring here.
