Tensura x Kumo desu ga, nani ka. Crossover.{COMPLETED}

A small change.

Rimuru noticed the telltale signs of a clone dying due to the many times her own clones had dispelled, so when Rimuru noticed this, she growled, grabbed the soul shard and a riple was send through the endless void. "A clone huh.!"
The black figure who was watching from afar was now revealed as the real Yuuki.

Rimuru looked carefully at the soul shard and said "If this is the full soul piece than the real Yuuki is probably millions of times stronger than this clone."
Rimuru's face contorted into a manic grin that would send shovers to all the people watching, including the real Yuuki and his partner.
His partner asked "When am I gonna be revealed though?" Yuuki said "Wait a little, you'll probably be revealed in like 4 chapters or something, could be more." A loud voice sounded out again "Yuuki, you're not allowed to break the 4th wall like that!"
Yuuki turned to Rimuru and said "Why not, they're gonna know soon anyway, right?" Rimuru facefalted and said "But it'll be a pain in the ass."
Yuuki nodded and said "True, but do we really care, I mean, it's not our mess, it's the author's mess." Rimuru nodded in understanding and said "Fine, but why wait so long if we could just fight right now?" Yuuki said "Because then the story would end to quickly and the author can't milk it much more." Rimuru shouted "Stop breaking the fourth wall, Yuuki."

After the bantering, Yuuki's partner had long disappeared and Rimuru just waved at Yuuki who casually walked away, Yuuki then turned his head and said "See you soon Rimuru, hope you can entertain me when we start fighting."
Rimuru nodded her head and said "Sure, but you gotta go all out from the start."

After Rimuru was finished fixing everything, she went back home. Back to Shiraori.
When she went back though, she noticed the change in her body structure and looked around, she then internalized and asked Ciel
>Ciel, I've just noticed the change in body structure and wanted to ask, how long has it been?"<

<Calculated, endless void = around 50000 years.
Internal dimensions = 2 months.>

>So I've been fighting Yuuki's clone for nearly 50000 years?"<

<Indeed master, due to the constant fighting, time started to twist and distort, the concept of time was messed up and thus you two spent nearly 50000 years fighting, while it actually only felt around a day or two long.>

>Has my power increased according to the time passed?<

<No>

'Shit, I just wasted 50000 years of potential power ups.'

>Did the original Yuuki grow in power than?<

<No, outside of the 2 months of power everyone gained, he did not gain additional power.>

Rimuru sighed out in relief and set out towards home.

After 4 seconds, Rimuru had already appeared outside of the kuko dimension, she passed through the barrier with ease and arrived back home, she then knocked on the door and was tackled by Shiraori.
Rimuru hugged Shiro while laying on the ground and asked "Can I get up please?"
Shiro got up from Rimuru and clung to her arm, when she entered the house she noticed Chloe with a big belly and asked "What's going on? It's only been 2 months since I've left." Shiro nodded and said "Yes, but it seems your energy had accelerated the birth of the baby by about 6 months." Rimuru grew visibly pale as she thought about it.

>Ciel, is it possible that instead of making the 9 months take 3 months that I instead made the 50000 years 3 months?<

<Affirmative, due to masters power, your children will inevitably remain in the womb for a longer time depending on how bad the compatibility is.
Compatibility with Chloe is 100%, Shiraori's compatibility is also 100%.>

>So if Shiro were to get pregnant at my hands, it would take about 50000 years for our baby to be born?<

<No, it would take approximately 2000 years.>
Rimuru sighed in relief and asked
>Why only 2000 years?<

<Species between master and Shiraori are closer in evolutionary state and thus the energy from both parties would require only 2000 years to fuse and form a child.>

The entire conversation with Ciel took less than a second, but Shiro still caught on and asked "Why are you looking paler than usual?"
Rimuru let out a breath and explained her conversation with Ciel.
Both Chloe and Shiro were surprised to learn that Rimuru had instead spend 50000 years away, but calmed back down when she explained the reason.
Shiraori asked "So you're not 50000 years older than me now, right?" Rimuru confirmed "I am indeed not. I aged the same pace you two did."
Shiro let out a relieved sigh and muttered "I'm happy I'm not that much younger than her."

Chloe had been excited to learn that the 50000 years was shortened to only 3 months, because that meant that she didn't have to spend a full 50000 years with child in her womb, she knew that she would never get rid of it or bring it in danger, but the thought of having to carry for 50000 years is not something she wanted to do.
The other reason was that she would be fine with it, because it would be Rimuru's child.

Shiro was still not happy, but knowing that she's only spending another 20 years here at most does bring comfort to Shiro's mind.
Compared to the 10000 years they spend together, 20 years was nothing.

Rimuru had prepared dinner in time for the two to wake up from their thoughts and sit down.
Ariel also came back home and joined the group, Shiro explained everything about it and Ariel also had a mind break, she recovered quickly and just sighed "There's never s normal day with you people around." Everyone chuckled and said "You know it!"
