Unrivaled Demon's Odyssey

'Let's step into my spirit realm.'

Five magical rings appeared around Nero's body and covered him as they started revolving and oscillating.

Then, the five rings shined with different colors, each resonating the color of his cores' maps.

Nero felt his body senses turning numb, and soon he found his body turning lighter than the air.

He opened his eyes and found himself in his spiritual realm. Upon glancing around, Nero sighed and shook his head in disbelief.

"I was prepared for the worst, but… this is on the whole another level."

When Nero was 13 years old, he entered his spirit realm for the first time. There he saw nothing, but an enormous citadel, made from nothing but the mixture of black and cyan, white and golden, and the red-colored ornates on it.

There were hundreds of colossal statues, but with no face, each wielding different weapons and wearing different types of attire, as though each one of them was from different eras. And in the center of the citadel, there was a giant tree.

Nero himself had no idea why there was a citadel in his spirit realm, nor did he know anything about the statues and the tree. But he later learned that the spirit realm is one's deepest and desperate call of imagination. However, Nero hadn't imagined his spirit realm to look like that.

Nero was in his prime age at that time, and he was learning celestial level magics and spells. And as he didn't have much knowledge about the spiritual plane, he wasn't sure what he should do.

But now, after stepping into his spirit realm eons later, it looked almost as if it was broken— quite literally.

The beautiful blue sky had turned purple, and the clouds had turned red. The moon was nowhere to be seen, and the sun had turned black. As for the stars, they were falling like rain.

The floors and stairs of the citadel were floating all over his spirit realm, and the statues were sinking in the endless abyss. But in all that, Nero could see something shining over the sky. 

  "Is it what I think it is?" He questioned himself.

Without wasting a single second, Nero jumped on the floating floor of the citadel, then jumped on the stairs. After jumping through over hundreds of floors and climbing over thousands of stairs, Nero finally reached the shining object.

He landed on the grass and sighed in relief: "So I was right."

It was a small floor with grasses on the ground and dozens of plants with numerous types of flowers of different colors, and at the center of the floor was a giant tree.

A smile appeared on Nero's face after seeing that tree. He walked to the tree and touched it before brushing his hand on it.

"I am glad to see you are safe and shining, Yggdrasil."

Everything other than the grassy floor was about to collapse.

Normally, this wouldn't have happened, but after Nero got his first core, the speed of the corruption increased, which was why his other empty cores were hungry for power.

"Hopefully, I can cultivate here and stabilize everything." Nero sat on the grassy floor and leaned his back on Yggdrasil.

He sat in the same position he was sitting in the sea and closed his eyes to start cultivating.

"...."

"....!"

"...us"

"Zeus!"

Nero slowly opened his eyes when he heard his name being called by Sophia.

"Zeus. Can you hear me? The dinner is ready."

Nero stopped cultivating and took a deep breath only to exhale it all out soon.

"Hours passed by in moments," he murmured.

He glanced around to see if his cultivation had any change in his spiritual realm or not, and he was baffled after seeing the new scenery.

The purple sky once again turned blue, and the clouds white. The citadel was rebuilt and turned even bigger and longer.

The statues were back to their positions, but some of them were missing.

Nero didn't remember them and didn't even care about them since he had no idea why they were there in the first place.

Yggdrasil had spread its roots in the entire spirit realm, and it was forming new lands and trees.

"It's coming back to life." Nero clapped to praise himself for the flawless achievement even after a long time.

Nero furrowed his brows and squinted his eyes as he heard the sound of the water flowing.

'Is this the sound from the sea?' He wondered, then pondered, 'This sound feels like it's from the same dimension.'

Nero glanced in all directions to find the source of the flowing water sound, but he couldn't find any.

Then, on a whim, he looked up at the sky behind him and saw a waterfall.

"What the—!"

There was a river in the sky, flowing across the clouds, and it was leading to a waterfall, going deep down the dark abyss.

Nero stared at the abyss for a while and slowly stepped back.

"I can't believe I just had the 'call of void' in my own spiritual realm." He sighed and uttered, "But I am curious about it. What would happen if I jumped down?"

He seriously wanted to jump down the abyss, but he didn't— or rather, he couldn't after remembering Sophia calling for him.

Nero stepped out of the spirit realm and opened his eyes in his real body under the sea.

He was surprised to see he was surrounded by fishes who were eating the mana he was emitting while cultivating.

"Let's hope they don't turn into monsters or die by overpower-ness," Nero sneered and stretched his legs to make contact with the sea bed.

"Hmm~ The ship has traveled quite a distance— around 700 miles. It will take me a whopping 30 seconds to catch up."

Thirty seconds were only a fraction for one, but for Nero, it was almost the same as 30 hours.

Sophia had used the same ability as Nero to make contact with him using the water.

When Nero was on his way to the ship, there was only one thought in his mind: 'I will let Sophi do whatever she wants to do with me— for tonight.'
