The salty air of the East Sea filled Kai's lungs as he opened his eyes. He wasn't in the dark spirit mine anymore. He was lying in a narrow, dirty alleyway.
In the distance, he could hear people cheering. "The King of the Pirates... Gold Roger... executed right here!"
Kai's heart skipped a beat. Loguetown? The execution of Gold Roger? Am I in the world of One Piece?
Suddenly, a massive man with a scarred face blocked the alley. He held a rusted sword and sneered at Kai. "Hey, brat! Hand over everything you have, or you won't live to see the execution!"
Kai looked at his thin, weak arms. In this world of monsters and pirates, he was nothing but a Zero-Rank trash.
[Ding!]

The glowing blue screen appeared, just like a miracle.
[Detected: Rusted Iron Sword (Poor Grade).]
[Trade Value: 5 Soul Coins.]
[Would you like to trade?]
Kai looked at the robber's sword. "I don't have it yet," Kai whispered, "But I will."
With a sudden burst of speed, Kai grabbed a heavy wooden plank and swung at the robber's legs. As the man tripped, Kai grabbed the sword.
"Trade!" Kai shouted.
The sword vanished into white light.
[Trade Successful!]
[5 Soul Coins received. First Trade Bonus: 1x 'Low-Level Observation Haki' Fragment.]
[Would you like to integrate the fragment?]
Kai felt a strange tingle in his mind. Suddenly, the world slowed down. He could "feel" the robber's next move before it happened. He dodged a punch effortlessly.
"What... what are you?!" the robber yelled in fear.
Kai stared at his hands. He was a trader now. And in this world, he would trade his way to the top.
