Reincarnated in the world of One Piece

To be able to eat 2 devil fruits no such thing is possible in the world of one piece . Everyone knows as long as an individual tried to consume 2 fruits you blow up instantly. Countless persons have tried different ways to see if they can eat a second but ended in failure. If not them dying directly, it would be the experimental subject that they tested it with.The world government ruled the world the for 800 years and along with the help of Dr. Vegabunk ,the world leading scientist must have tried every sensical and non- sensical way to see if there actually can't be 2 devil fruits users. With years of experimenting, it was finalized there can't be anybody who can eat 2 devil fruits without being blown to bits.

For blackbeard's case who eat the yami yami no mi fruit which control darkness, he didn't eat a second fruit. The dark dark fruit allows the user to absorb devil fruit power from a dead user's body into there own so he didn't technically eat a second fruit at all. However, Joshua case is different he is able to eat another devil fruit without having to worry about being blown to pieces.

Therefore, with said if such news were to be known to world persons would be both shocked and filled with endless greed . Who woudn't want know how to eat a second devil power and gain a another power, the whole world would endlessly hunt him down capture and tortue him to know how he did it.

After a round of laughing Joshua calm down and looked at the two devil fruits, his eyes swept over to the mythical fruit but shook his head. What Joshua has really heard from the system is that mythical devil fruit is actually storm Aphosis mythical beast from egypyian mythology. It was said that Aphosis was a powerful serpent lord who controlled devastating earthquakes and horrible storm abilities which now can be seen where the storm ability derives from.

"Even though the fruit is seriously eye catching it is better to give a capable person for my crew," Joshua sighed as he placed the devil fruit in the system space. Thinking of how the state of the battlefield when such person enters, he couln't help but grin.

Not another second wasted he took a bite of the black flame fruit.

"Bluahhhh... its really horrible just like the characters in the original works say." Joshua said with a distorted expression but he kept eating it until he was finished.

This...

Horrible, negatings fluctuations was given off as the air became gloomy and suffocating. Anyone who were to pass by here would have difficulty breathing and be inflicting by dark and negative air. The trees, leaves seems to have lost its vibrant colour and at visble speed became withered and black. Joshua slowly got up, right now his body was half elementalized with pitch black flames with a diameter of 2m which was burning endlessly .

"Good, terrifying lethal flames," Joshua said slightly suprised, the surrounding surface, trees were burning endlessly. Even though it is slow but it is seen with the naked eye. Joshua looked to his left and saw a bird with most of its body engulfed in the black flame crying out in pain, while it drops from a small tree to the ground . Trying to move desparately, the bird was burned from the skin down to the very bone was swallowed by the flame untill it became nothingness. For an instanct Joshua thought of Sasuke's amaterasu.

Joshua took up the sword controlled the flame power and ran it along onto sword and quickly thought of a move.

"Death slash."

A weird yet terrifying arc was released in the air, the horrible black flames caused the temperature to rise several grades. Countless negating thoughts , chaos, sorrow, hatred, despair made the surrounding area more depressed and gloomy. The weird arc with the flames dances wildly as the hit the ground, creating a semi circle arc as it slowly burns the trees in the area of attack from the roots up .

"Really horibble," Joshua commented. He was very satisfied with the fruit power ,now it just needs to be further developed so the might of the black flame fruit can be displayed.

"With this logia any physical attack would be ineffective unless it is an armament haki user," he added. He didn't have to worry about that now cause he would not be meeting such persons yet.

After that he stopped the continuous burning in the surrounding area and went into the woods.

3 months later-

burn

The dreadful yet weird black flames ran widely towards the behemoth that it was before giving the impression like it were alive. As if countless dead souls was densely packed wailing with various negative thoughts.

roarrr..

The behemoth that was about 12m in height which looked like a mutated rhinoceros gave a strong but painful growl that shook the leaves causing them to sway violently. On its dark grey body, it had various burns more than that of 3rd degree burn. There was also numerous sword slashes both big and small, which leaked out nauseating flesh and blood . Even though he dodged some of the attacks it still suffered serious injuries.

From the surrounding area, on could notice the deep gloomy air, the trees were already cut apart but still burning due to the black flames. The leaves have already shriveled, the animals who coudn't escape where burning to death. The land that was plaqued by the black flames had already lost all hope for ever rejuvenating, it was now completely dead.

The surrounding area looked terrible.

The one who did this was standing in the midst of all what was happening as he watches the beast calmly galavanting. The cold, emotionless eyes looked indifferently without the slightest care about the surrounding area. His disleveled hair made him look more fierce, in addition the frighteneing aura that continued to be released made him look like darkness himself.

"You think you can just dodge my attack," he sneered.

"Wishful thinking..."

"Go with,"

The flames that were dodged by the beast, quickly turned back and began to chase. What is suprising is that, the flames in the surrounding were continuously being attach as it now created a half finished sphere of a height of 14 ft releasing strong negative breath .

Roar..

The beast growled as he smelled death upon him, he wanted to escape but the routes were continuously cut off making it extemely anxious. But it then saw an area where the flames has not reached and hurriedly try to get there.

Everything that was happening was in the boy's cold dark brown eyes.

He gripped the worn out blade tightly and slightly moved it then carried his hand back to the original spot.

When the beast thought its going to to escape he sped up happily, but when he wanted to take another step again it went downhill.

booom...

It body dropped shaking the ground slightly and blood started to spread widely. The beast was shocked and confused but he still desparately looked behind. What he saw was his 2 front feet were chopped off with blood gushing out from it and a little to the right the there he saw his chopped off feet .

The speed of the blade was too fast that he know not when this happened.

This made him terrified, it still desperately try to move forward, but at that same period, the bright and sunny day suddenly became night. He looked up and saw the horrible distorted flames that looked like a corrupted dragon roaring at him ferociously as it quickly drown down at him, leaving him in only despair .

Booom

The earth shook a pit of around 20m was created, the heavy landing of the beast causes a slighlty violent shockwave to occur. This caused a few trees to be uprooted while the land began to appear cracks.

The wailing, screams rang out in the woods, causing the rest of beasts to jump in fright making them hurriedly move away from where they were. Likewise the beasts, so did the bird as the fled in different directions.

Then it all came to an end.

The boy unhurriedly walk to a nearby tree and sat down, rested for a few minutes then opened back his eyes.

"Well thats done."

The boy is Joshua.
