I am a little early here

The world of One Piece, The Holy Land Mary Geoise

In a dark and dreary cell, Chu Yang felt his heart sink as he listened to the wails of the other prisoners. Within a month of his transmigration to the world he was abducted, sold as a slave in Sabaody Islands, and was bought by a Tenryuubito as a slave—some luck he has.

Other people transmigrate with at least a decent system, he on the other hand will be branded as a slave for the world's most disgusting filth. The stench of burned flesh traveled in the air as he gagged on it. Being from the modern world such cruelty made him sick to his stomach.

In the cell next to him were three girls of similar age to him. Compared to him who's having a panic attack they seemed relatively calm, as if they were accustomed to it. The three girls were completely different in their appearances. One had a vibrant shade of green hair and the other had orange hair. The one in the middle, seemingly the oldest was the only one with normal black hair.

"Kid, are you new here? I suggest when you are taken by them do not resist, no matter what happens do not fight back and annoy them. Otherwise, you might get tortured or worse get killed before you have any chance" She warned him. Calming his nerves down he nodded to her as she softened her expression

The wailing in the background ceased as the atmosphere eased a little. Feeling curious they started chatting with him "Kid what's your name?" "Don't call me kid, my name is Chu Yang. Besides you don't look much older than me" He retorted. "Chu Yang? Quite the weird name you have there. My name is Boa Hancock, you can call me Ane (older sister) kid"

Hearing her name, he looked at her again and chastised himself for not recognizing her. Then again, he was only familiar with her adult form. So, the plot would begin somewhere around 17 years in the future. But he wasn't sure when Fisher Tiger would arrive and save the slaves. He can't put his hopes on a man he's never met before, and even if he tried himself the defense of Mary Geoise is nothing to be scoffed at. He turned towards Hancock to ask her some more questions when he heard someone approaching his cell.

It was the Jailer. It seems they were ready to mark him with the 'Hoof of the Dragon'. Hancock suddenly reminded him again to keep his composure. He couldn't help but laugh at his situation. With a 'Boom,' the cell doors were kicked open as a man in a Dark uniform stood in front of him. Chu Yang tried not to show a timid expression as the guard grabbed him off the ground and sneered at him as he dragged him off the cell. Watching him leave Hancock hoped nothing bad happens to him. There were many times prisoners were tortured by the Jailers on a whim. Most died even before being branded by them, almost all of them being human. The Nobles loved different species, and even if one went missing the guards would have to pay dearly.

Chu Yang was thrown on the ground as they ready the hot iron rod from the fire. The Jailer picked up the rod and walked towards him gleefully as he got ready. Like a cornered animal he tried to scare away the Jailer. "I have seen this look a million times and it's not going to change much kid," the Jailer said as he raised the rod and slammed it on his chest. The mark took only a second to imprint, but the pain persisted all over his body.

The Jailer sadistically pressed the rod even more on his chest, as if getting some twisted pleasure from his pain. Chu Yang's body writhed in pain as he held his screams through pure force of will. The pain brought out his rage as he stared down the Jailer, his eyes turning scarlet from it. Seeing his hysterical look the Jailer nearly dropped his rod as he took a few steps back.

When he came to his senses, he realized that Chu Yang had already passed out from the pain. He sneered and kicked the body across the floor, angry that a slave nearly made him scared.

Meanwhile, Chu Yang's mind was in a completely different place, a magnificent Palace that was weathered down to ruins. The weight of its history was apparent as there were rows of thrones densely packed. Most of them were destroyed save for a dozen of them in decent condition. Two of them were glowing bright red as if blood was spilling out of them. There was a figure sitting on one of them, as they got closer their appearance was revealed. Two people looking the same stared at each other in shock.

At that moment a sense of bond made them realize they were the same person. They experienced each other's memories, and both concluded. Somehow during the process of transmigration, they got split into many pieces and ended up in different places altogether. "So, you're from the Naruto world huh?" said Pirate Yang. "The times we got in are shit. We're so back in time that the knowledge of the plot doesn't even matter anymore."

"I know right? I got sold off in an auction the minute I arrived here, talk about having shit luck" said Pirate Yang. "Your situation is way worse than mine, at least I'm not a slave" Shinobi Yang joked. "So which period have you arrived in?" Pirate Yang asked. Even though they had their memories shared it was only till they arrived in their world. Shinobi Yang said thoughtfully "I'm not sure, I'm somewhere in the Sengoku era. The Shinobi villages have not been established yet" Pirate Yang took a breath of cold air as he remarked "The Sengoku era? Man, what a time to be born"

"By the way, I'm also a Senju, Senju Yang," remarked Shinobi Yang.
