That Time I Got Reincarnated as a Slime: Restarting life all over again!

Diablo

The location right now is the headquarters of the Phantoms, and at the sky of it was a man standing clothe in black and was laughing creepily.

[Kufufuffuu I wonder if Rimuru-sama will give me a reward if I annihilate these fools who dares to defy him]

It was Diablo, he seems to notice that Cornu wasn't dead when he fought Testarossa, and was now here to finish him off.

'Hmm... It seems like Cornu was the only Commander here right now? Then where is Zalario?'

Diablo seems to think about Zalario whom presence wasn't found anywhere in this otherworld.

Diablo was a bit wary where he (Zalario) is but destroys his thoughts right away.

[Well I just need to lessen the burdens of Rimuru-sama then kill those who oppose him later on]

Diablo then focuses his eyes on the phantoms in the castle

[Kufufufufu let's get started then]

***

Cornu was drinking some tea in a place that seems like a control room for the phantoms, he is sitting comfortably there without knowing the threat he is about to face off.

[Hey give me some sweets to eat] Cornu told his servants

It's not like he needs to eat, it's just that his servants learned the way of cooking from the Cardinal world and became fond of it.

[Yes! Cornu-sama]

Cornu then nods happily, and while he was thinking to rest and get comfortable, suddenly an earthquake was felt.

[What!?] Cornu shouted

[What's happening?] He added

[It's a... There's a man in the air right now!] his adjutant said

Cornu was surprised by it, he thought 'Who was it? Who would dare to go and attack them here'

[Show me the monitor]

[Yes]

When Cornu was shown the monitor, he saw a man dressed in black floating in the air and was staring down right at them.

He saw this man before―No, he knew this man. This man is one of the strongest existence, one of the first beings ever created in this world. The man that even Guy Crimson respects and the man whom Feldway hates the most.

[Primordial black, so it was you huh] Cornu said

[Sir what should we do?]

[I'll go face him, I'm the only who can match him anyways]

[Yes sir]

Cornu then goes outside and meets the Primordial black

[What are you doing here Noir?] Cornu started the conversation

[kufufufufu To think that the battle between Rimuru-sama and Zelanus will have an effect even here? Truly what a blessed life it is to serve Rimuru-sama] Diablo said, ignoring Cornu

What Diablo said was the truth, it wasn't Diablo who caused the earthquake. Infact it was the fight between Rimuru and Zelanus.

Why did Diablo knew that Rimuru fought Zelanus? Because the other Patrons told him so.

[Hey don't ignore me!] Cornu shouted at Diablo

After what Cornu said, Diablo lost his smile and looks at Cornu

[Huh...? Kufufufu I don't want to talk to a talking corpse like you though] Diablo said

[Corpse? Did you just say that I'm a corpse?]
