The three-dimensional plane has countless sub-layers. It is where the special Qi beneath the fifth level could be found. The fifth-level Qi and above can only be found in higher-dimensions.
Anti-Entropy thoroughly studied this regard during the past year. The combination of honkai technology and immortal cultivation produced some jaw-dropping artifacts. There is the automatic spirit stone condenser. Naturally, there is also the automatic Qi dispenser.
It utilizes a special Pri-ARM made with the Gem of Desire. Its ability to manipulate fluids enabled them to capture these special Qi with ease. Over time, they improved this artifact to the fourth grade by converting Soulium into its immortal cultivation equivalent.
Since then, Anti-Entropy possessed hundreds of fourth grade Qi with varying effects.
Now that they were trapped inside this special Bubble World, they immediately brought out all the destructive ones.
"This feels more thrilling than setting off nuclear bombs."
After a thorough inspection, Tesla's golden eyes reverted to its prior color. She chose to specialize in Qi-Gazing which made her suitable to lead the main arrangements.
Einstein's voice came from the other side of her comms.
"You have more penchant for explosions than I do. Wasn't your re-designed mecha a part of it?"
"You won't understand. Shi Tian is a visionary. All of his mech designs are very cool."
Einstein was speechless. Tesla was convinced by Shi Tian's 'vision' by bringing over all sorts of Gundam models in reality.
"The inspiration for this came from it. Turn A. Don't you remember?"
"...That's why it felt so familiar."
Over three hundred destructive-type Qi are gathered together to form a special formation. Along with the Gem of Desire, they are all housed within Soulium nanomachines. Tesla and Einstein are responsible for tweaking them to perfection. Tesla focused on the nanomachines part while Einstein was left incorporating these Qi to them.
Finally, Welt Yang is responsible for manipulating this huge undertaking. The soulium they used all came from his usage of his remnant Herrscher Authority.
Tesla directed her words to Welt Yang.
"You know what to do. I want to see the Moonlight Butterfly in full view!"
"Got it."
Welt Yang, who was on the receiving end, responded to her request.
'It doesn't sound bad.' He thought. 'Should I direct more funding for Arahato's remake..?''
It was he who supported Tesla whenever she geeked out. He is also Shi Tian's supporter when it comes to truly knowing mech designs.
In short, the two of them love mechas with their heart.
It did not take long to finish setting things up. Midair, Welt Yang took full control of the soulium present. His slightly pale countenance slowly recovered under the use of pills. His forceful usage of the Herrscher Authority remnant exhausted him greatly.
Like the brightly lit stars in the sky, motes of colorful lights emerged. His connection with the soulium was top-notch.
Welt Yang sensed the automatic changes undergoing inside them and no longer held back. Tesla and Einstein reconfigured them already.
All that's left is to strike hard!
He fulfilled Tesla's wish and spread these soulium akin to a pair of wings.
Hum-!
Buzz-!
All sorts of matter was destroyed save for its user. He did not waste any time as he converged all of the soulium into a single point, then to a line.
This Bubble World has an inexhaustible barrier. It is not as strong as the Bubble World personally created by the Sea of Quanta, but it is more than enough to keep Herrschers trapped for a long time.
The best choice is to converge all their power into a single point—akin to a needle—to destroy the barrier.
That was what Welt Yang did. The soulium nanomachines attacked the "barrier" in a single point.
Doctor MEI… or rather, her remnant will born out of the Bubble World looked at it happening in real-time. Her gaze turned to the dozen or so "S-Rank Valkyries" (i.e., Foundation Establishment cultivators) and sighed.
She could already see the outcome of Kevin's fight. A hint of relief could be seen in her eyes.
"I… put too much burden on your shoulders."
The last bit of humanity left from Doctor MEI, the same person who could willingly sacrifice thousands for the greater good, was the regret of being powerless to do anything but to place humanity's burden in Kevin's shoulders.
Rumble-!
The Bubble World soon collapsed along with the Previous Era's regrets.
*****
There are only two requirements for the Herrscher of Finality to emerge:
First, the Authority of Origin.
Second, defeat Deliverance Kevin.
We already fulfilled one of the requirements.
Kiana's attire changed into the familiar Finality battlesuit. It is the same attire that I tore during our chaotic dual cultivation sessions.
…
"Fu…"
I have to calm down. Dual cultivation addiction is a real thing. It is only five years. What would happen if we did it for hundreds of years?
Moderation is… not required. We progress in immortal cultivation with it. This also turned out to be the proper way to use the [Xiutian Art].
I have to strengthen my Tao Heart..!
Kiana opened her eyes. The star-like pattern on her irises glowed with more mysticism. Her already extraordinary temperament is further improved.
"This power feels familiar…" She muttered.
Her words prompted me to look at her more thoroughly.
Aside from her extremely gorgeous appearance, the power inside of her changed. It was no longer Void, but Finality. She possessed the authority of all Herrschers, including mine.
Unfortunately, it is only half of the complete Finality. The other half is held by Kevin—the fragment they stole with the Previous Era backdoor.
The [Encompassing Eyes] fed back some information and rearranged a few thousand knowledge points I once read.
{Authority: Void Refinement Realm (Incomplete)}
Finality…
It belongs to the Void Refinement Realm.
I readied myself to this possibility. The Herrscher of the End possessed a Divine Transformation Realm Authority.
Finality, who is stronger than the Previous Era's End, surpasses that margin.
Nevertheless, it does not remove their weaknesses over weak body and mind. These two do not match the realm of their authorities, causing something as trivial as mental attacks to harm them greatly.
"I feel uber strong now!"
Kiana's child-like remark made me laugh. It made her realize her small blunder, giving her face a tinge of blush.
"You're not wrong. Maybe you can defeat me now."
"Even in bed?" She asked eagerly.
"No. Do you want to try it again?"
"...How are you so strong?"
I felt speechless at her thought process.
Despite gaining Finality…
Her first thought is to use it during dual cultivation!
