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

Dragon's eyes narrowed, and he immediately covered his palms with domineering aura. He stepped quickly on the ground, then transformed into the wind, shooting out like a sharp sword, instantly closing in on Jin's body.

Then, the corner of his mouth rose, and in the next moment, he changed his attack method, using both hands and feet to unleash powerful force simultaneously, his attacks falling on Jin's entire body like a storm.

Dragon's sudden and fierce offensive had no effect on Jin, as if those attacks didn't exist, allowing them to land on his body.

Then, he clenched his palm into a fist and threw an ordinary punch, directly hitting Dragon's chest, sending him flying.

Dragon touched his violently aching chest, his face a little pale, panting heavily: "As expected, elemental transformation is useless in front of a master..."

Immediately afterward, he turned into a gust of green wind and blew towards Jin.

"Pretty durable..."

Jin shook his hand. He felt that every time his fist hit Dragon, it would inexplicably slide to the side, as if he was hitting flowing air, the feeling was exceptionally bad, and there was no pleasure of a solid hit.

"Clap clap clap......"

The fierce confrontation continued, with the two sides exchanging punches and palm strikes endlessly. Their clothes had long since turned into fragments in the battle, drifting away with the wind.

"Pfft!"

Another head-on collision, Dragon staggered back a few steps in the air, relying on stepping on the breeze to stop his body from retreating.

He wiped the blood from the corner of his mouth, his eyes flashing as he looked at Jin. He had used all his skills, but the other party was still standing in place, without moving at all.

"......"

"Alright, I've almost figured out your strength." Jin said loudly, "You can go off the field and rest."

After speaking, Jin didn't wait for Dragon to react, and jumped to a high altitude with a moon step, then fell down suddenly.

"Let me show you this palm technique from the sky."

Dragon felt a strong threat approaching him, so he decided to use all his strength to meet it.

Suddenly, a strong wind rose, and the wind rolled up sand, gravel, broken branches and other debris, surging into the sky.

"It's useless."

Under Jin's palm, the strong wind suddenly collapsed, and the branches and dust all shattered and scattered on the ground.

A slap hit Dragon's head.

"You lost..."

"......"

Under the winter sunshine, the training ground and its surroundings fell into silence. Gazes filled with deep joy stared at the two people in the center of the training ground.

They, the onlookers, had expected this outcome. Their Colonel Jin had never been defeated by his peers.

"I actually lost..."

Dragon lay on the training ground, his palm placed in front of his eyes to block the annoying sunlight.

This was the first time he had failed since he was born, and it was a complete defeat. This first time in his life was really not something to be happy about.

"......"

[Ding! Congratulations to the host for completing the side mission: Defeat the wielder of the raging wind.]

[Ding! You have gained the approval of Monkey D. Dragon.]

[Ding! Monkey D. Dragon's favorability towards you has increased, please continue to work hard.]

[Mission Reward: Training space usage time +36 hours, Beli 20 million, Information on a disappearing island, Auction invitation card]

Jin: ???

Standing on the field, joy comes from the sky.

The training time continues to increase, which is enough for him to cultivate for a while, and these Beli are just better than nothing to him. This money is just a string of numbers in his eyes.

What really makes him curious are the latter two rewards. The disappearing island is the one that someone reported earlier, right? It is specially used as a reward, which means that the island should have some unknown secrets.

As for the invitation, he needs to find a place where no one is around to study it carefully.

Jin glanced at Dragon, thinking that this guy with thick eyebrows actually likes this kind of thing. It was useless to reason with him for a long time, but after a beating, he became honest instead.

Jin looked down at Dragon lying on the ground, with that elusive smile still on his face.

"It's really troublesome, as expected of someone who grew up under the training of those old guys at the headquarters."

Devil Fruits are not something that ordinary people can get, and Dragon's fruit is even rarer, so envious.

"And I also have to thank you for the rewards you brought me."

Dragon laughed self-deprecatingly, only taking Jin's reward to be the joy after victory: "What about the headquarters, what about the four seas, haven't I still been defeated by you."

"Can I ask you, why are you so strong?"

Dragon moved away the palm blocking his eyes, and became strongly curious about the person who defeated him. Losing is losing, he just needs to improve himself, and then catch up with his pace, so that he can be satisfied.

Hearing Dragon's words, Jin also asked himself this question in his heart, is it luck, is it hard work, is it the life-and-death struggle in the training space every time?

He smiled and did not answer directly.

"Strong? I don't think so, there are too many strong people in this world..."

Edward Newgate, Gol D. Roger, Shiki the Golden Lion, the Five Elders, Im, any of these people can easily defeat him, and his goal has always been these people.

"Next, you should take a good rest, maybe I will have fun things to call you for later."

Jin turned around and walked towards the office, he still has a pile of training to complete.

"You just came here, it's normal if you don't understand Jin." Kuzan sighed, "I've been by his side for so long, and I haven't seen him exercise much, but every time I see him, I can feel that he has become a lot stronger."

"Maybe this is a genius, oh no! A monster..."

"When I first met him, I could still go three or seven with him, but now...it's all tears to talk about it..."

Hearing Kuzan say this, Dragon didn't feel any better, but felt even more pain.

......

"Damn! An invitation to a human auction house?"

Holding the reward issued by the system, Jin directly cursed, what's the use of this thing for him.

The auction house is still on the Sabaody Archipelago, which is hundreds of thousands of miles away. This thing is like waste paper, and he can't possibly buy a living person back...

On second thought, the Sabaody Archipelago is a resort, and it seems good to go there for a trip.

But Kuzan's level is a bit difficult to pass, that guy probably won't let him get his way...

Kuzan, who was dealing with the mess on the training ground, sneezed: "Alas~ I'm so difficult..."

"No, without conditions, we must create conditions to go." Looking at the invitation, a sly smile appeared on the corner of Jin's mouth, "We also need to bring a few people with us."

There will definitely be a lot of interesting things happening at the once-a-month event...
