The Last Regret - That Time I got reincarnated as slime

The Final battle

As I said ciel created a new world, It was the replica of the same world veldanava had created.

"This is.......a new world?
Not this world only but all the other worlds veldanava had created are here."
Guy said.

"What?"
"Thats ridiculous!"

They were surprised as usual but I ignored them because I have more things to do.

I summoned my subordinates.

"We are here my lord."
All of them greeted me.

"This place?"
This was the first time I saw Diablo surprised because whenever I did something absurd he would always react like he had expected that from me but it seems that even Diablo didn't expected this from me.

"Yup, A battle is going to take place here soon and I don't want the innocent to caught up in our mess thats why this is the place I created for the battle."

"As expected of our lord."
He soon regained his calm.

"Now, It seems that we need to bring our final guest."

"Final guest?"

"Ciel, Summon everyone from other side and also change this place into a endless plain."

[Understood]

Everyone present there were covered in a barrier because the place was changing its structure.

The world became a never ending plane.

Suddenly a flash of light emerged and the final guest appeared, this was my first time when I saw them in person.

Veldora, Velgrynd and Velzard were together, All of them were in thier spiritual form.

"Forced teleportation?" Feldway said.
"Yeah, It seems that we are invited by the 'Rulers of the world.'

"So, What is the reason we are summoned here, Guy crimson or Should I say the Mediator of this world."
Miachel said.

"Well, I didn't brought you here, It was rimuru and also the two behind you is more than enough reason for us."

"These? They are useless now, I have already collected their dragon factors and I thought of returning them but after witnessing something amusing here I don't think I can return them.

That slime has an unusual presence around him and also that is related to the last piece of dragon factor which is needed to resurrect our god Veldanava."

"What does that mean?" Guy said vigorously.

"Calm down, This type of reaction is not suitable for someone who is appointed by the our god himself.

Let me tell you something, When I collected the dragon factor from the remaining true dragons, I thought it would be enough for me to resurrect the god veldanava but it didn't worked.

I understand that something is still missing but only thing I can remember that is related to Dragon factor is milim and Ivraje but the problem is milim doesn't have a Dragon factor and her pet dragon's factor is still underdeveloped so we can't use them.

Thats why After I absorbed the other three true dragons' factor, I became strong enough to fight with Ivraje and I did.

I fought with Ivraje, even though I had my strength and the other three dragon strength it was very close battle.

I took his factor too but it was not still enough to resurrect our god.
I implanted a soul in Ivraje and made him totally loyal to me.

I thought that it would be better to return the true dragon to where they came from and think of a new idea to resurrect our god.
