Alex ran out of the tight room, and into the wider pathways of the cave.

The ghost king followed him and immediately began its attack.

​​

As if Alex became the gravity center of this place, rocks began flying at him and even the stream of water began spilling into his direction.

Alex skillfully dodged the attacks he could dodge and pulverized the rocks he couldn't dodge.

"I'm dealing with an expert right here, are you a Silver Immortal or above?" The ghost king clicked its non-existent tongue.

"Not really, I'm just the...

"God of humanity!" Alex launched Prometheus at the ghost king.

However, right before it touched him, the spear turned direction and launched right back at Alex.

'His gravity control powers are annoying...' Alex charged by himself at the ghost king.

Suddenly, he lost his footing and felt himself falling.

The ceiling became the ground.

"AAAAAAAH!" Alex groaned in pain.

He felt like his heart was being crushed under its own weight, and the pain was unimaginable.

"Of all of the ghost kings you could fight, you chose me..?" The ghost king giggled.

Alex inhaled deeply and started holding his own breath.

However, he lost his footing again and began falling towards the ground.

Right as his body hit the ground, the ghost king bolted at him.

Its slimy fingers reached for his neck, but Alex's Prometheus made its way for him.

Unfortunately, gravity reversed again, and he felt Prometheus loosening up from his grasp.

An idea came to him at the moment.

"I have an advantage that you don't!"

The ghost king looked at him with confusion.

"I studied Physics in high school!" Alex's appearance began transforming.

His body became taller and more muscular, and his eye became a piercing red.

Prometheus liquified and changed its shape following his transformation.

An extremely heavy, golden spear was now in his hand.

Ares' Incarnation provided Alex with the highest physical strength possible, and with his feet on the wall, he threw the heavy spear like a lance towards the ghost king.

"What is the way to counter gravitational force, you asked? With an even stronger force, of course!"

The ghost king was unprepared, and the spear pierced through his body.

When the ruby touched the incorporeal slime, the sound of water touching a hot pan echoed.

The ghost king screamed and tried to wield the spear, but because he changed the center of gravity of the room, the spear 'fell' towards Alex, who easily caught it.

"How do you have a tool that counters our very existence?!"

"Ghost king, I vanquished the Devil's avatar with this ruby, you won't last," Alex felt extremely overbearing as he recalled their encounter with Angra Mainyu.

The ghost king's body had a glaring gap where Prometheus hit him.

At that moment, gravity returned to normal, and Alex fell onto the ground.

The ghost king felt the threat to his existence and suddenly transformed into a black mist.

The black mist flew out into the crevice Alex had widened earlier.

Along the way, it destroyed any footholds they could use to climb.

However, what it didn't know, was that...

Alex could fly!

His wings immediately flapped and followed the ghost king.

It had left the cave completely, and they were both under the searing sun.

Alex perceived a strange phenomenon taking place.

Around the ghost king, the vegetation was dying off and turning into ash.

And the ghost king, himself, began turning more and more into a 'human'.

His bones were formed from stone, his muscles were formed from spider webs, his blood was water, and his skin was of tree bark.

"When we, ghost kings, feel a threat to your existence, we can abandon the ghost egg and our rule over ghosts to become earthly beings..."

"Now, your ruby can't affect me in any way!"

Suddenly, Alex burst into loud laughter.

"You really go into a fight without knowing your enemy, don't you?" Alex mockingly asked.

"What do you m-

The ghost king noticed that his body was decaying.

"WHAT'S HAPPENING?!"

When the ghost king transformed into a vegetation-like creature, Alex knew it was checkmate for him.

He remembered a fight he had won in the past.

Back then, he was weaker than now, and yet, he still won against the King of the Babylonian Gods, Marduk.

Marduk had mastery over vegetation and almost defeated him through suffocation.

However, Alex had Aphrodite's Essence.

Aphrodite's control over fertility wasn't limited to humans, but also stretched somewhat into vegetation.

Just as he withered the roots away in that fight, he destroyed the ghost king's body in this fight.

'I have to admit, her powers are pretty versatile.'

Miraculously, the ghost king could still speak.

"I recognize a loss."

Suddenly, thick, golden chains restrained the ghost king.

Two people had appeared.

One of them was a tall and slender man, with white robes.

The other was short and stout and wore black robes.

The similarity they both shared, was their scary faces.

The tall man looked at Alex and said, "We are the Heibai Wuchang, we carry souls to the Underworld!"

"Okay...?" Alex was rather puzzled.

The short man stated, "Yan Wang wishes to see you."

A screen-like portal suddenly appeared out of thin air.

On the other side, a large man sat upon a platform.

The man had red skin, bulging eyes, and wore white robes. A white rectangular piece of fabric fell onto his forehead and read, "King."

Alex instantly felt like he should escape from this place.

"You there! You! Stop!" The man called out.

Alex still moved away.

"Please!"

Alex stopped and turned around.

"I am Yan Wang, absolute ruler of the Underworld."

"Nice to meet you...?"

"You defeated one of the ghost kings!"

Yan Wang coughed and began telling an unsolicited story.

"1 century ago, the ghost emperor escaped my realm along with his ten ghost kings..."

"And, my servants can tell you...just how much I HATE WHEN PEOPLE ESCAPE MY REALM!"

The tall and short man unanimously exclaimed, "Yan Wang hates when people escape his realm!"

'That's exactly what he said...' Alex awkwardly laughed.

"And, I can never find anyone who wants to bring back the ghosts to their rightful domain!!!!" A blue vein crept up on the red skin of the King of the Chinese Underworld.

"So, here's my offer to you, you defeat the 9 other ghost kings and the ghost emperor, and I'll give you a reward-

"What's the reward?" Alex immediately asked.

"I didn't think that far ahead...Servants! Do we have anything of value?!"

A small, goblin-like man approached Yan Wang and gave him a plump peach.

Yan Wang cleared his throat, and exclaimed, "This is a peach of immortality! I hate these because anyone who takes them can never die and come to my realm! So, defeat the ghost emperor and kings and I'll give it to you."

'A peach of immortality? Like Ambrosia?' Truthfully, Alex wanted Ambrosia for a long time.

But, over time, he realized that the elixir was incredibly rare.

If he could get this peach of immortality, he could gift it to Crista, and she'd become a goddess too.

"I have to defeat this 'ghost emperor' and 'ghost kings' to get it?"

"Yes."
