Prologue:

Garden Eden; Mount Purgatory; The Afterlife

Having just fallen victim to truckkun on his way home from university, I found myself dumped into a river. Incapable of swimming in it, sank like a stone until realizing that I could still breathe despite being deep underwater. Able to get a good hold of stones lining the riverbed, I began my rise back up.

Climbing out of the river, the sun setting over the horizon, I was greeted by a winged woman in a white floaty dress. "Hello there. I am Matilda the guardian of this garden."

Still staring at her large fluffy looking wings, I asked her. "Are you an Angle?..." Before I realized something more important and added. "... Am I dead?"

Shooting me an enchanting smile, Matilda replied. "Yes, to both."

Taken aback by the angles honest answer, I asked her bluntly. "So, am I going to heaven or hell?"

"Neither. You are one of those unique cases..." She answered before she hesitantly added. "... You are going back to the lifing into a world of your chosing."

Smelling bulshit, I questioned her further. "Why my chosing?"

Her being taken of guard by my question, I could see her calm angelic facade crack as he said. "That is because..."

"Don't lie to me. Somebody screwed up isn't it..." I further questioned, my mind running at the speed of light coming up with the most likely scenario. "... I wasn't supposed to..."

"Just shut up, will you!..." Matilda suddenly jumped me, sealing my mouth with the palms of her hands. "... You are right, all this is somebody's fault. That somebody being my little brother Bacchus from the karma department. That dammed guy is not taking his job serious ever since Big Brother Michael prohibited him to party with that Roman Emperor Caligula."

"So, you are covering for your little brother?"

"Yes, I do. So could you please tell me where you want to go? I have heared that the 'World of Fire and Ice' has become quite popular among you Millennials."

"Game of Thrones? No, thank you! Even rich people die there..." I rejected her suggestion. "... But what's in it for me since I am supposed to keep quiet about your brother's screw up?... How about a 'System'?"

"Okatu!"

"What?"

"I said 'okatu' since you must have red one to many webnovels..." She explained before adding. "... Oh, and NO system!"

"What about cheats like immortality?"

"Nope!"

"A super weapon?!"

"Definitely NO!"

"How about...?"

"Just forget it! No universe breaking or bending objects or abilities. The most I can do is designate the corpse of unborn fetus you will be inhabiting."

Listening to her limitations, come up with a possible loophole.  "Than I want to be sent to a world were I have control over Time and Space!"

"That's impossible!..." Matilda blurted out before realising my genius. "... Or maybe not. I guess there might be a universe with that particular ability. But are you sure that you want that particular ability?"

"Yes, I am."

Waving her left hand, Matilda said. "Than be gone to the World of One Piece!"

Karakuri Island; Future Country Baldimore; Secret Underground Lab

Standing around a transparent water filled tank with a muscular male body inside, two young scientist, Dr. Vegapunk and Caesar Clown worked tirelessly.

"Does he still have some form of brain activity?" Asked Vegapunk upon checking his instruments.

"Yes, Subject 435 is still with us. In a deep coma, but still with us..." Answered Caesar Clown lazily, not even checking his instruments, before adding. "... The reinforcement with Sea Steel is complete, no rejection. Didn't I tell you the DNA of Neptune was the key."

"Yes, yes, I know you are great..." Replied Vegapunk dismissively still very much concerned about his patients health and mental wellbeing. "... I still don't think, that we should give him the Space-Time Fruit, since the last subject was devoured by it."

"The World Government want their perfect weapon..." Commented Caesar before adding. "... Sometimes you have to risk some good eggs to make the perfect omelette. This is not any different."

"I am not sure, if I an agree with that statement of yours, but so be it..." Commented Vegapunk as he pushed some buttons. "... Feeding the Jiku-Jiku* Fruit."

That said, pureed devil fruit mousse was pumped through one of several tubes and automatically force fed to Subject suspended in the transparent tank, whose body instantly started to convulse as he struggled against the invasion. Meanwhile the water surrounding him started to boil as the Devil Fruit wreaked havoc inside of hin.

After struggling for some time, the man eventually fully awakened and fought against his confinement. As time went by, soon the high pitched sound of him flat lining rang out and the man stopped all movement.

"Well I guess that's it... Commented Caesar Clown before adding sarcastically. "... Just another failure. Atleast he didn't end up devoured by the last guy."

"And here I was hoping for a miracle..." Said Vegapunk before registering an anomaly on his instruments. "... Hello, what do we have here?!"

Looking perplexed at his own instruments, Clown asked curious. "What? What are your instruments picking up, that mine aren't?"

"Mind waves. I guess 435 isn't dead just jet..." Answered Vegapunk before he unconsciously chanted. "... Come one, come on... I know you can do it 435. I know you can become the new Vulcan."

As if wanting to reply to the Scientist's chants, the space surrounding the subject bend before it caved in on itself. As their instruments failed and machines exploded, Vegapunk and Caesar helplessly witnessed as the Space-Time ripped open to suck 435 now aka the new ancient weapon Vulcan in. Before he vanished without a trace, the two scientists could see for a brief moment his pupils eyes glow white and a smirk played on his lips.

Stunned how all of a sudden their test subject was able to escape, the two scientists heared a faint voice echo inside their minds.

"Vulcan has awakened... All hail the Uncrowded..."
