One Piece: King of Martial Arts

Impel Down City, six underground floors of the Deep Sea Prison.

"Ace..." Kaixia Jinbei gasped and looked at Ace who was chained to the wall.

"Boss Jinbei, have you been beaten badly again?" Ace lowered his head weakly and glanced sideways at his side.

"This little flesh pain doesn't hurt at all..." Jinbei panted and said with a look of unwillingness: "What hurts is my heart and my unyielding benevolence..."

"Crash..."

As soon as he finished speaking, the prison door was unlocked again.

"Squeak..."

The door opened, and a figure was thrown in by Jailormon, and landed in front of Ace and Jinbe with a 'pop'.

This man is tall and strong, with strong muscles and a tough and handsome appearance. At first glance, he is a man of great strength.

"Navy?" Ace glanced at the people on the ground expressionlessly. From this guy's clothes, you could tell who he was before he came here.

"Why are the navy also imprisoned?" Kaixia Jinbei glanced at Jailermon.

A cold light flashed in Jailermon's eyes, and he walked in with a big stick in his hand. He picked up the big stick in his hand and gave Jinbei another blow with a 'bang' sound.

"Uh ah..." Jinbe gritted his teeth and endured the pain, watching Jailermon leave with unyielding eyes.

"It hurts..." As soon as the door was closed, the figure on the ground moved.

"Are you awake?" Jinbei looked at this person with blood on his forehead.

"Where is here? Why does my head hurt so much?" The figure sat up, rubbed his head and looked around.

Jinbei felt the pain on his head and said sadly: "This guy should also have been hit by that bastard."

"Navy, why are you here?" Ace looked at the figure with a cold face and asked, "They still don't want to give up. Do you plan to ask you to ask something from my mouth?"

"Huh? What kind of navy? Yeah -" The figure shook his head, his head finally sobered up a bit, but he soon screamed in pain from a sudden stinging sensation.

"This guy must be seriously ill..." Jinbei looked at this person indifferently and wanted to point his finger at his head, but unfortunately his hands were locked.

At this time, two memories suddenly poured into the figure's mind, making him a little confused.

One is the memory of his previous life. His name is Ma Ruifeng, a 25-year-old veteran college student.

Just a second ago, he was on his way to the supermarket for shopping. The next second, he saw a faster box truck crashing into the old woman crossing the road.

Out of the instinct of a veteran, Ma Ruifeng rushed forward without hesitation and pushed the old lady away.

In exchange for this behavior, he was sent away by this truck commonly known as the ‘Gateway to Another World’.

As we all know, trucks of all kinds are the gateway to other worlds.

Among many time-travel plots, the proportion of truck time-travel can definitely exceed 50%.

Another memory comes from the body himself. His name is Ka Xiu, and he is a genius navy lieutenant.

At a young age, he has already mastered the Sixth Form of the Navy, awakened his Armed Color and Knowledge Color, and became the best candidate for the future general.

It’s a pity that no one is perfect!

Just yesterday, when Ka Xiu went out on a mission, he got a devil fruit on a pirate ship.

In line with the principle that if you try it, it won't hurt inside or out, and no one will notice it anyway, Kaxiu ate it without reporting it.

The Devil Fruit that Ka Xiu secretly ate was the Gravity Fruit. In his ecstasy, this guy also knew the low-key hidden strength.

But when he went back to drink in the evening, Kaxiu got drunk out of joy.

The key is that this guy's wine is not that good. After getting drunk, he went crazy at the banquet and accidentally killed a brigadier general and a senior officer who were caught off guard.

In anger, Admiral Akainu threw this guy into the sixth underground floor of Impel Down City.

"I've traveled through time..." After understanding all this, Ka Xiu patted his forehead and sat up and looked at the two people in front of him, and was immediately stunned.

"Hey, hey, I'm asking you something!" Ace rolled his eyes impatiently.

"Are you Ace?" Card Xiu raised his finger and pointed at Ace, then turned to look at the other person and said nonchalantly: "Are you Kai Xia Jinbei?"

"That's me!" Jinping closed his eyes expressionlessly and asked, "Please explain your purpose of coming."

"Why are you here?" Kaxiu blinked with questions in his head, and then said with a wry smile: "The fact that I can see you here means that this should be the sixth floor of the underwater prison..."

"What's going on with this guy?" Ace glanced at Jinbe inexplicably.

"I don't know, it seems a little strange." Jinbei shook his head.

"Ace, your brother Luffy is on his way to save you!" After calming down his mind, Card Xiu recalled the plot here, looked at Ace and said something surprising.

"Nani?" Ace raised his head in disbelief and shouted, "Why is that idiot here?"

Card Xiu shrugged and said: "Aren't you his brother? Don't you still understand his temper? Knowing that you are locked up here, how could he not come here to save you."

"This idiot..." Ace smiled bitterly and shook his head: "How can this be a place where he comes and leaves whenever he wants?"

"Let's put aside the issue of developing the Gravity Fruit for now. The most important thing at the moment is to fool these two people, and then successfully sneak into the protagonist's team, so that I can also become the protagonist!" After thinking about it for a while, Ka Xiu had his own Decide.

In the original world, Ma Ruifeng also read many pirate fan novels. Most of the pig feet inside chose to carve out their own route and go it alone after traveling through time.

Ma Ruifeng felt that this was very boring!

It wouldn't be interesting if we didn't follow the main character Luffy, the troublemaker, okay?

Besides, I have never heard of this Gravity Fruit Card Xiu. According to the fruit level settings in One Piece, this gravity fruit should be a higher-level superhuman fruit than the gravity fruit.

Just like the upper level of the Shao Shao Fruit is the Lava Fruit, and the upper level of the Snow Snow Fruit is the Frozen Fruit.

"Do you believe in destiny?" Card Xiu thought quickly for a few seconds, then said with a sly face: "If you believe it, then you can see him when you are executing! Because he is the son of destiny, No one can stop him."

Ace and Jinbe looked at each other after hearing this, and both saw the confusion and confusion in each other's eyes.

"There's something really wrong with this guy's head!" A few seconds later, Ace spoke his mind.

"Indeed." Jinbei, who was still standing aside, agreed.

"Oh no..." Ka Xiu's eyes widened, he patted his chest and shouted: "Everything I said is true! If you don't believe me, think about it carefully. Throughout his journey, Luffy has almost always been able to deal with any crisis. Turn bad luck into good luck!"

Ace and Jinbe shook their heads in confusion. They didn't follow Luffy everywhere, so how could they possibly know what Luffy had gone through.

"I was careless... I have read the comics. How could they, the people in the game, have a God's perspective like mine..." Raising his hand and patting his forehead again, Card Xiu sighed speechlessly.

At the same time, Luffy, Candle Man and Joker are on their way...
