One Piece: Start as a mythical beast, practice to become stronger

Among a group of slaves dressed in gorgeous attire, a beautiful woman stood out exceptionally.

She was confined in a glass sphere filled with water, her fair skin shimmering, a soft blue silk fabric adorning her head, her limpid eyes filled with sorrow, and a slender tail gently swaying—clearly a mermaid.

Jin An's heart jolted, but he quickly calmed down. He hadn't expected to actually see a mermaid at this auction. He thoughtfully observed the scene before him.

So... the Celestial Dragon outside came here after receiving news of a mermaid?

The mermaid was constantly restrained, her eyes revealing a yearning for freedom and helplessness, but Jin An didn't linger his gaze on the beautiful mermaid. After shattering the glass dome with a finger pistol, he opened the cells indiscriminately.

Then he left, as he still had to unlock the restraints of these people.

Without the constraints of the glass dome, the mermaid took a deep breath of air. Although the air was foul, she relished it.

Swimming freely in the water, she supported herself with her hands, her tail gracefully slicing through the water, leaving the water surface she was once unable to escape, breaking free and heading towards freedom.

The mermaid gratefully gazed at Jin An, expressing her gratitude in a silent way.

Jin An felt a sense of satisfaction from doing a good deed. He always acted according to his own ideas, and he would do anything as long as it made him feel content.

He released these slaves simply because he wanted them to live freely and choose their own lives. As for their safety after being released, Jin An couldn't take responsibility for that.

"You're so weak, obediently go behind me!"

"But..."

"No buts, obediently give me your spot! Otherwise, I'll break your legs."

The order of the line was the order of having their collars removed. To escape the threat to their lives as soon as possible, many people began to have wicked thoughts.

Hearing the discordant voices coming from the line, Jin An's brow instantly furrowed.

He couldn't say he didn't understand these people's thoughts, but understanding didn't mean agreeing. He remembered this troublemaker and those who had similar ideas.

The person behind pulled the girl who was cut in line, signaling her to endure it: "Don't provoke him, we can't fight him."

"We were all captured here, why is he still bullying people like this?" The girl was puzzled.

They were all in the same boat, yet before they even escaped this den of demons, they were already starting to bully each other.

This world doesn't care about 'misery loves company.' To survive, people here are capable of anything.

"Little girl, I've remembered you. Wait until we get out, you just wait!" Under Jin An's gaze, the man left a harsh remark and scurried to the back of the line.

"What you did was dangerous, remember! Run as soon as you get out, that person definitely holds a grudge against you," the person behind the girl reminded her.

"......"

The girl stood there blankly. She didn't know what she had done wrong. Her father had always told her to be polite and obey the law since she was a child.

She had always done so, but why was she captured here? Why was that person so fierce? Why...

......

Jin An began to remove the restraints of these people.

The design of these collars wasn't complex. After studying the ones on Long and the others' necks, he had already mastered the key points. Although there seemed to be many people here, after getting familiar with it, it didn't take much time to finish.

Those who had their collars removed stayed where they were. It wasn't that they didn't want to leave, but they didn't know the situation outside and were afraid to go.

"You can leave," Jin An continued to do what he was doing. There were only a few people left, and he would be done soon.

"But... the guards outside..."

"As for the guards, they're all gone." In the perception of his Observation Haki, there were very few people in the auction house who still had a life force.

A slightly bolder person cautiously walked out of the area where the slaves were imprisoned. After discovering there was no danger, they quickly ran out.

Two minutes later, that person ran back, the excited expression on their face impossible to hide.

"Everyone, we can leave, the guards outside are all gone!"

Those who were still hesitant didn't say anything more after hearing the man's words and ran straight towards the exit, afraid that if they were too slow, something unexpected would happen.

After everyone had run out, Jin An looked at the last person in front of him: "You're the last one. Be careful after you get out, don't get caught by slave traders again."

"May I ask, can you tell me, what is your name?" The mermaid who remained at the end looked at the person who saved her, her eyes sparkling with anticipation.

Afraid that the other party might have some concerns, she continued to add, "My name is Serena, and I run a coffee shop on Fish-Man Island."

"Do you know what it means that I wrecked this auction house?" Jin An asked in return.

Serena thought for a moment and replied, "You will become a thorn in the side of the auction house and their backers."

Jin An rolled his eyes and joked, "Knowing that, you still ask for my name, do you want to use my name to exchange for money?"

Serena was so anxious that tears were about to come out, and she said somewhat aggrieved, "I... I didn't mean that, I just really want to know your name."

This man saved her life and also left a deep mark in her heart. Although they might never meet again in the future, knowing his name would at least let her know who saved her.

Jin An looked at the beautiful mermaid in front of him and sighed inwardly. He didn't expect that after saving so many people, she was the only one left who wanted to ask for his name.

"Jin An," Jin An said his name. Although mermaids hated humans, they were extremely concerned with credibility, so there was nothing wrong with saying his real name.

Moreover, he had a certain fondness for mermaids who ran coffee shops. The people on Fish-Man Island twenty years later gave Jin An a good impression, being loyal, righteous, and helpful.

And that shop owner, like the woman in front of him, was a great white shark mermaid. Perhaps they were relatives.

Maybe if he passed by Fish-Man Island in the future, he could get Sherry to give him a free fortune telling. Unfortunately, Sherry didn't seem to be born yet, otherwise it wouldn't be bad to go to Fish-Man Island now.

"I will definitely remember your life-saving grace for the rest of my life. If you come to Fish-Man Island, please be sure to look for me at the coffee shop, I will do my best as a host."

Serena bowed to Jin An, then leaned forward, resting her head on Jin An's lap, waiting for him to remove her shackles.

Jin An saw the position of the collar clearly and skillfully removed the collar from Serena's neck, then coughed lightly.

"So fast?" Serena blushed slightly and gently moved her head away.

Jin An touched his nose: "The air here is not good, let's go out first..."

"You go out first," Serena looked at her tail, "I'll go out later."

Jin An also realized that it was very inconvenient for mermaids to move on land, but it was not safe to leave her alone here.

"Let me take you out," helping people all the way, Jin An gritted his teeth and squatted down directly to ask Serena.

Serena opened her arms and wrapped them around Jin An's neck, her body curled up in his arms.

She let out a soft whisper, as faint as a mosquito's hum.

"Um... please..."
