I Am Undying

Elihim didn't bother to keep his voice low that other people passing by couldn't help but hear it. However, they just thought it was something else like in some fiction stories or game or something like that so they didn't react that much. It's not like there's a lot of people out there that'll just interrupt a stranger's conversation just because they heard something weird.

"You mean a weaker Devil is equivalent to five Draggers?", Rin felt chills on his spine. If he didn't face off Dragger and defeated him, maybe he will feel more intimidated.

"Five Draggers? Dragger isn't even close to being an average. We just went to the Level 1 of the Colden Cage Arena, there are still up to Level 5 and the difference in each levels are huge."

'Somehow, I just now know what the name of the place where I staked my life. Ah, wait, I didn't staked my life in many different ways. Is that a death match? It shouldn't be.', Rin subconsciously evaded to think about the Devils.

"Weaker Devils are supposed to be in Level 3 or 4.", Elihim reminded Rin again.

"Ah, Master. Now I feel scared.", Rin was getting anxious. Even though he couldn't die, not dying is worse if he met a Devil based on his master's words.

"Ahaha, don't worry. I'm still here, as long as you're not ready yet, I'll fend them off temporarily.", Elihim assured.

"Master~", Rin wanted to hug his master right now.

"Although if they come at me with their full force, I may not even stand a chance?", Elihim scratched his own head in worry.

"Huh? Master, they can defeat you? I thought that you could defeat the strongest here on Earth with just a blow from your mouth?", Rin worried and hoped that it's one of his master's joke.

"Yeah that's true."

Rin sighed in relief.

"But…"

'Oh no, no buts…', Rin cried inside.

"Just ten greater Devils can match the strongest, Reyure, the 'Greatest Master'. You expect me to blow a breath hundred thousand of times?", Elihim furrowed his eyebrows.

'Huh?', Rin looked at his fingers to looked at how many time ten is again and tried to multiply ten and a hundred thousand, "Huh?", it's that he's dumb but it's just way too shocking that his mind was denying it. "A million????"

"Oh, right, the population of the Underworld exceeds trillion since it's way bigger and older than your Earth and the Devils have longer lifespan that many reach higher stages of strength.", Elihim was talking so casually but what he was saying was catastrophic.

"No, I'm not exaggerating, ahahah."

"M-master, how can you laugh? What if those trillion came to Earth for revenge? And it's all my fault.", just thinking about it made Rin regret so much, he felt that he felt something that he had not in a long time. Rin got a cold feet.

"Don't react too much before I even finish. If those trillion Devils can come here then we're already finish but there are still rules to be followed when transcending worlds. He made a restraint to those who wants to travel across different worlds or there will be imbalance."

"He?", Rin felt a huge relief and wanted to learn more about these restraint.

"Well, you know, He.", Elihim pointed above.

Rin understood and nodded.

Elihim sighed, "I planned to tell you a this after you can manipulate Natural Energy at will but it looks like I need to tell you now."

"…"

"When a Manipulator accustomed himself and practiced Energy Arts well enough, they have a chance to form an Energy Core which can produce Natural Energy by only itself. It is like a system, like an electric generator you have here on Earth.", Elihim didn't bother going into much details since it is still unnecessary, "Obviously, Natural Energy is natural from the world itself. We just manipulate it and use it then it goes back to the world where it came from.", Elihim paused for a moment for Rin to digest the information before continuing, "It would be unnatural if the Energy in the world would suddenly increase when one travel from another world with its own Energy Core."

"So you're saying there is a restriction to those who have Energy Core?", Rin guessed.

"Spot on! In this world, there can only be up to five God Stage Energy Core, nothing more, since that's the only limit this world can hold and although, there are just three of us Gods currently here, there are just enough Otherworlders with an Energy Core to make up for the slot of one God Stage Energy Core. Originally, there are four of us Gods here but since you killed Nathan, there is a slot for another God Stage Energy Core which is equivalent to a lot of Devils with Energy Core. Understand all that, Godkiller?", Elihim teased.

Although Godkiller is a pretty badass nickname, it will only lead to chaos for Rin. "You mean a number of accumulated Devils with Energy Core that is equivalent to one God Stage Energy Core can come here?", you can hear Rin's anxiousness through his words.

"Well, I'm here and those Devils with no God will be no different from angry mobs to me so it'll be easy to scare them off.", Elihim said as he threw something Rin which Rin caught with his two hands.

Rin wanted to ask something about earlier when Elihim said he couldn't take all the Devils if they fought with full power but Rin decided to keep that question first, "What's this?", Rin looked inside his hands and saw a ruby-like ring, he then looked at Elihim
