hearing how quickly and the desperately of her master voice, Ciel open up and tell Rimuru about her plan of restoring the world back to it original form "there many ways to restore our world master, easier way is simply create a similar world or go back and stop ourselves"

"but... Because I know master will have object  creating a similar world and the timeline is... unstable right now"

"so... I come up with another way... one that suit your request"

as Ciel said that her voice turn bit ominous but Rimuru doesn't notice it since right now because all of his focus right now is aim at the solution that Ciel about to said

See how focused Rimuru is Ciel begin her speech about the foundation of the world

"As you know this world is built to withstand the power of Veldanava but what make this world different from the others? Why is this the only world that can handle Veldanava godlike power?"

"different.... Different..." ponder at Ciel question a bit, Rimuru realize what she asking was true the cardinal world of tensura is the only world that can handle multiple power house like Primordial demon, Angel of origin, spirit queen and many other powerfull entity/race

But then it hit him, the only reason that for Tensura cardinal world can be so resilient is because of "the Dragon Factor of a true dragon..."

smirk up, Ciel quite supprise and impress that her master can pick up the sign but again it not like it to hard, Yuuki one of her master past enemy did mention this before

"you are correct master, each True Dragon have a Dragon Factor and each of those symbolize an aspect of the cosmology"

"Velgrynd acceleration, Velzard deceleration   and Veldora the incarnation of chaos"

As Ciel continue her speech, she create the image of the cosmology itself so her dear master Rimuru can understand it better "it's also why the cardinal world so resilient that much, because this world have 3 concept backing it up"

"but when we was back at our world I only sense one concept present which is acceleration"

"wait what!?? if so then where is the other 2? where is Velzard and Veldora!??"  Rimuru ask, waiting for Ciel to explain the where did the 2 of them when missing

"master did you forget you change the timeline?"

"my guess is when we safe your past self it leading to there no Satoru to reborn and no master to safe the world from yuuki"

Hearing Ciel explain her hypotheses on why the world is ended in this timeline Rimuru start to wonder "Ciel may I ask... What does all of this  have to do with your plan of restoring our world?"

let out a sign although she not supprising on the fact that her master doesn't understand what she saying but she can't blame Rimuru since if she was to explain to herself from the past then no doubt she won't understand either

"It's okay if master don't understand, the main thing that we have to do now is to find Veldora and Velzard back"

"By combine Turn null and the Dragon Factor of the 3 true dragon I can restore the world back like when we never left it"

Ciel answer is like honey sweet and soothe, it sounds really perfect to the point of the other person don't understand a thing they still know what to do and Rimuru is that person

Back to the outside after the conversation  with Ciel in his head, Rimuru begin to explain the plan and what he needs to do this point onwards

"Hm... So how are you planning to find my brother and sister? And if you fine them I double they will know you let alone come with you" Velgrynd speak up, point out the little but also essential part of the plan

as quick as Velgrynd ask the questions, Rimuru answer it with the help of Ciel

"I will use Universal Perception that got amped up by Turn Null"

"And thought your Dragon Factor we can locate Velzard and Veldora dragon Factor"

Although still skeptical about the plan and the feasibility of it but similar with Rimuru, Velgrynd had to agree to it as it is the only plan they can come up

So the only thing Velgrynd can do is reluctantly agree with this plan

And with that the mission was clear, by using the Universal Perception that got amped up by Turn Null on Velgrynd Dragon Factor, Rimuru easily locate the location of Velzard and Veldora Dragon Factor

"I'll be going now wish me luck" with those final words Rimuru blackout, his body go limp like a ragdoll as his subconscious and soul leave his body

Seeing that Velgrynd doesn't supprise and turn her back at Rimuru body while whispering "you better be success... And safe..."

in spite of still being mad at him, Velgrynd can't deny that Rimuru is all she have left and if he gone for good then Velgrynd will be trap here in this endless voir forever

But... Turning her back at Rimuru body isn't a smart thing, because as soon as Velgrynd whispering those words

Rimuru body begin to move and and when it lift it head up, a crimson red eyes glow with a nefarious intent behind it glazing right at Velgrynd
