"Hahahahahah...." Arthur laughed on top of his voice.
" This is it, with this power I will stand on the top of this era." Arthur roared. His eyes had become bloodshot with a crazy twisted smile creeping on his face. He gave off a vibe of a gambler who had finally won a lottery in the casino. Crazy waves of his laughter created madness in the air.
" Unlimited life, unlimited energy with an invulnerable body and mind, Hahaha ..., I have become what everyone aspires to be. I am Immortal." Arthur proclaimed madly looking towards the skies and sea.
" I will see the best scenery, fuck the best women, bathe in gold and diamonds eat and drink the luxurious, take all that I want to be it women or wealth." He growled his oath, with nature as a witness to it.
Regrets, there was a lot of it in his previous world whether it was wealth or women he wanted but couldn't have. But not anymore, in this world, he will have it all and live like an emperor. Though his powers were godly he had no interest in being one. The desires that were confined in darkest depths of his heart had already begun to break the shackles that bound them, and knowing the bestiality of his current world he no longer thought of binding them.
Looking around constantly towards his surrounding, Arthur decided to go inside the forest to hunt for food. Though he didn't need to eat, besides habits don't change easily, and he had nothing to do himself. Also, he needed to cover himself since he was naked currently.
" Beasts come play with daddy Arthur, I will give you death at the end of it" Arthur shouted. Making a lot of noise in his walk. After roaming in the forest for nearly an hour, Arthur came across the first living being in this world face to face. It was a huge rabbit nearly ten-meter large. Arthur, being a little nervous, more excited started attacking the huge rabbit. He punched towards the rabbit with all his strength. No air breaking sound, no breaking of ground, no simply nothing happened. Arthur's punch didn't even manage to make any kind of damage to the rabbit. After punching the rabbit Arthur kept the punching posture, while he was thinking, "Shit! I forgot that I became immortal not superman. Oh! this giant bunny will definitely squash me."
The rabbit looked at Arthur and became annoyed. Although Arthur's punch was like a mosquito bite for it, no even worse as mosquito bite also causes a little pain but Arthur doesn't. It felt Arthur had no respect for it since he attacked it. Rabbit thought to help Arthur reach heaven.
With incredible speed, it punched Arthur. Arthur felt that the world was twisting around him, no the truth was he flew out and crashed through a lot of trees and finally hit a rock nearly fifty meters away from the rabbit. The most incredible thing was except being dizzy due to constant vision shifting, Arthur had no damage on him. Yes he was not even injured in the slightest.
"Yes, yes, yes I have truly become an Immortal." Arthur yelled," The void particle changed my body and has made me invulnerable, although my strength has increased to only 10 tons".
"Hey bunny ready to dance?" Arthur questioned and rushed towards it.
The battle between Arthur and the rabbit has been continuing for an hour. The rabbit has already become completely afraid of him, but Arthur was completely annoyed with this fight. He couldn't harm the rabbit in any way and was getting tossed by it. Luckily he also gained Busoshoku Haki, as the rabbit was using it. Arthur guessed he might be in New World as animals here are capable of using Haki.
Getting tired of this seemingly stupid fight Arthur escaped from the rabbit. Deciding to use fruits and berries for food he took another hour to collect them, and returned to the beach to eat. He didn't care whether they were poisonous or not since it wouldn't cause any harm to him. Eating quietly on the beach Arthur recalled his battle he rabbit and found his shortcomings. His attack power wasn't enough to cause damage to the monsters in new world.
Although he could use haki unlimitedly to increase his attack power, his power still wasn't enough to cause harm to monsters like Shichibukai, Yonko, or the Navy generals. Knowing his current combat power Arthur felt he would increase his strength first and then turn this world upside down.
Envisioning his future "what shit Yonko, what World Government I will become this world's only emperor" Arthur thought.
Although his future would be very comfortable Arthur decided to solve his current problems of shelter and clothing. He was very embarrassed to be naked on this island.
With the thought of finding a suitable shelter, he started further exploring the beach. After 30 minutes of exploration, he found a shipwreck, "finally something helpful in this wretched island" thought Arthur and started climbing it. Reaching the deck he looked for some usable materials. Searching around for nearly an hour found some useful materials.
First, he found the most important material, ie. clothes to wear. He found some torn trousers and many sailor clothes, though they were in bad condition some of them could be used as he was already wearing baggy pants.
Second, he found treasure boxes full of jewelry, gems, and some important maps. And third he found a lot of weapons though they only consisted of flintlocks and swords or blades and other cold weapons. In the captain's room, he found something which looked liked the captain's journal though he couldn't understand them. Lastly he found himself a grayish, rusty longsword which reminded him of Asta's demon slayer sword, though his sword was longer nearly reaching 2.5 meters in length. Arthur didn't need this weapon but he was curious whether it would turn into a Kokuto if kept infusing his haki to it.
After looking some more he decided to use this ship as his current base on this island and went to the captain's cabin. Before falling asleep he was completely excited for the upcoming days and was looking forward to his journey in this world.
