Rimuru Tempest X Omniverse (Fanfic X Crossover X OC)

Chapter 3: Preparation for Entering the Dungeon

In the cave where Rimuru is

Rimuru POV

Rimuru:"Wh-what is that??..That's too much!"

While shouting like that, I almost lost hope of resurrecting my comrades until Ciel spoke again.

[Relax master, the more you evolve to a higher level, you will become stronger, and moreover, if you evolve to the Supreme Slime, you will be able to revive Benimaru and the others one by one.]

Rimuru:"Is that true?"

[Yes, but the time required is uncertain, because their souls are in a different dimension]

After hearing Ciel's statement, I calmed myself down a bit and asked Ciel

Rimuru:"What are the levels anyway?"

[Let's start from Rimuru-sama's current level.  Rimuru-sama is currently at the Ultimate Slime evolution level, Above this evolution level is Supreme Slime]

Rimuru:"then after that I have to evolve 8 more times huh......"

[It seems you misunderstood master, you have to go up 10 levels, and I only mentioned one level which is Supreme Slime]

Rimuru:"So you mean there are still 9 more levels??"

[You are right]

Ohhh shit, this is really giving me a headache.  After I finished complaining to myself, I started talking again.

Rimuru:"Alright....how do I evolve into a Supreme Slime? Do I have to visit several dimensions and gather strength?"

[Lucky master, you don't need to go to another dimension, because the energy here is denser than your previous world]

Rimuru:"Good...But before that where are we?"

[Looking for existing information,
...... Found successfully.  Analyzing planetary structures, ...... Done.  It seems we are in a world called Artania which has 5 big continents with many kingdoms.  Currently master is in the Huneira continent inhabited by Humans, Beastfolk, and Dwarves.

In this world there are many races such as Elf, Beastfolk, Skywing, Dwarf, Spirit, Dragon, Vampire, God, Human and Demon.  Here, all of the existing races are still in the war against the Demon King.

In this world there is also a summoning magic that can summon people from another world and become heroes in order to help defeat the Demon King.

Usually, people from other worlds have great power when summoned here, which is why Heroes are needed to fight the Demon King.]

When I heard that I was silent for a moment and tried to digest Ciel's words properly.  After a short silence, I was surprised by the God race that was here.

Rimuru:"Eh....God? Is there really a God race? How strong are they?"

[Rimuru-sama need not worry, they are only as strong as Veldora]

Ehh...... The gods in this world are only as strong as Veldora?  Also, what the hell is that 'Hero' from another world?  Are they from the Earth I lived on before reincarnating?  Or from another world?  I'd better save the questions.

[In this world there are also things called Artifacts.  An artifact is an item of immense power which is much needed against the Demon Lord.]

Rimuru:"Is that so..... By the way how strong are the Artifacts here?"

[Only as strong as a Legend Class weapon]

Rimuru:"So? Can you find a way out of here?"

[Yes, currently master is in a dungeon.]
