Underworld... Underground Secret Base...
The Devils who heard the figure just said those words started laughing. They laugh because of what the man that stood before them is just a normal 'Human' as he leaks no aura of the sort.
Silver just stood there, watching them laugh at him as he checked the Devils ranks, 1 is a High-Rank Devil while the others are all Mid-Ranks.
"Just what can you do? You lowly human!" said one of the Mid-Class Devil
"Human, who sent you here and what business you are here for!? Don't you know that this is a facility of the Naberius House one of the remaining 34 Devil Clans?!" said another Mid-Class Devil who boasted the name of Naberius.
"Now tell us who sent you here and we might let you leave, it would be a waste to let that handsome face of yours to rot away hahaha!" mocked another Mid-Class Devil.
'This idiots, did they even think. How could such a lowly human enter without any of us noticing him? Don't even mention, we have guards and he just entered the room before we noticed him!' thought the High-Class Devil.
Silver hearing their questions, chuckled and said "Me? As I have said before, I am your doom and don't worry no one sent me here"
Silver then stopped time and slowly walked towards the girl that is currently tied up. Upon reaching her, he undid all the ropes that are binding her, and after doing so he carried the girl in bridal style as the girl is too weak to stand up in her own legs.
Silver activated his {Instant All Zero Skill} and in the blink of an eye, the girl's scar and bruises disappeared, the girl felt the changes on her body and felt no more pain and being carried by someone, slowly opening her eyes which has more life in them now compared to before.
As she opened her eyes, what she saw made her froze, she couldn't recognize the one who is carrying her but she did not do anything because she can feel the warmth coming from the figure who is carrying her.
Silver noticed that she finally gained her consciousness back, he looked at her and said "Don't worry, you and your sister will be safe from now on" and walked out of the door carrying her.
The girl hearing what he said started to let out tears in her eyes and said " Thank you " in weak tone for she did not have the strength to speak louder.
As they came out of the room, there is a little white-haired girl standing there and with an anxious look at her face. The little girl saw the ones who came out of the room and she quickly recognizes both of them and started to run towards them with tears in her eyes.
The girl in Silver's arms saw the figure running towards them and also quickly recognize the figure. The figure is no other than her little sister who she sacrificed herself to protect, Shirone!.
Upon seeing her sister she struggled to break free from Silver who slowly put her down when she started to struggle albeit with little strength she had.
As Silver put her down, she also started to run towards her sister, and as soon as each other is within each other's grasp, they hugged each other and started to cry their hearts out.
The remaining 10 guards heard the sound of crying which was loud enough for them to hear started running towards the sound, but before they can even get a glimpse of the sight of sisters.
Silver stopped time again and made a portal and put them all to where he put the others before and stopped his time skill after doing so, the only ones that are still in the realm of time stop are the ones who are in the laboratory/experimental room/lab.
Silver slowly walked towards the sisters, and as he walks towards them, the two sisters noticed him and looked at him with a thankful look in their eyes to which silver just smiled.
"I will be getting the two of you out of here now" as Silver made a portal and took the sisters and entered it.
Underworld... Somewhere...
A portal suddenly started forming and three figures can be seen coming out of it.
They are Silver, Shirone and ???.
"Thank you for saving us from that damned place, my name is Kuroka" gratefully said the one who was tied before who now said her name is Kuroka.
"Nice to meet you Kuroka, my name is Silver, Silver Blaze," said Silver with a smile on his face. Kuroka blushed when she saw the handsome face of Silver and with a smiled in it then looked away.
"Sister, are you still hurt? your face is red " asked Shirone innocently.
Kuroka hearing her sister made her blush more and said "No, it is just your imagination"
Silver seeing them really cared for each other smiled, a genuine smile from the bottom of his heart and said"Wait for me here I'm going to blow that place up"
Shirone hearing him asked, "Silver onii-chan are you leaving us here?"
"No, I will just go back to that place and make sure no more things will happen and be repeated to what happened to you and you and the others" explained Silver
"Please come back soon Silver onii-chan," said Shirone in a worried tone
"I will, don't worry I will be done in a few minutes, ok?" said Silver as he ruffled the hair of Shirone.
"Umm, be back soon Onii-chan," said Shirone
"Thank you" is what Kuroka could only say.
Silver just smiled at her and opened a portal leading to where he was before.
Underground...
Silver ported back, but this time he is no longer calm, his eyes started changing to golden color with a black crimson slit in his pupils as unleashed his aura.
Inside the experiment/lab room, the time has been restored and the 5 figures remaining was confused, because only the human is there now without the girl.
Silver's aura that has been unleashed made the Devils fell fear because this was the same aura that had appeared years ago and destroyed many things causing massive damages to all.
The High-Rank Devil thought 'Could it be him?! But it is impossible he is just a 'human' before!'
Suddenly he remembered that Ophis and Rose were looking for a 'Human'. Upon realizing he loudly said, "HOW COULD WE PROVOKE SUCH A BEING!!!"
The other 4 heard him but did not reply as they are all shaking in fear, fear that they never had felt before.
Silver just stood there as he watched them tremble in fear, he said "Well hello there, we meet again. Are you prepared to feel and suffer what have you done to all of those you experimented at? But I will tell you what you will experience is a million times more worst!"
"Please, please, please oh great being please spare us! We will never do such things again! Please, I beg you" begged the High-Class Devil.
"No, I asked if you are prepared. Did you think you will be spared? Don't make me laugh. Well then, go and repent all your sins and suffer for eternal damnation" said Silver as he opened a portal leading to where the sent the other Devils are and put them all in it.
Space...
A portal opened, 30 to be exact and what came out of it was the Devils in the underground from the secret base of Naberius Household Branch where they make their experiments.
When the Devils came out from the portal, they felt fear, more fear than they ever felt before not just fear. They tried moving, but none of them can move some even tried to do everything they had but nothing.
The only thing they can feel is fear and HOT, yes hot, so hot that they just wanted to die.
What they can see in front of them a planet but not just any kind of planet, the planet is a full colored orange, which sometimes explodes in some places but quickly reverted back.
Of course, the Planet/Star is the SUN!
They are 100 of miles away from the sun, they tried everything they can to get away but nothing will work, soon they noticed that they can breathe, but if it's for others they might or definitely die instantly.
Silver made it so they can breathe.
Slowly but surely, they are being pulled by the planet inch by inch, meters by meters as it gets hotter and hotter, they all wish to die but they just can't.
Soon, some started being burned alive as they cried for help but no one can help them, as time passed, the rest that is still alive but also started being burnt as they scream.
After that, they all died by being burned alive.
But,
It seemed like time reverted back for all of them because they are floating again to where everything started.
Realizing what is happening and what the figure said to them, they then truly realize what he meant by those words.
This is truly... Eternal Damnation!!!
