[OP]Chapter 7: The White Light Chakra Sabre

The pirates charging towards Kaminari were all electrocuted and fell unconscious one after another.

With their flesh and blood bodies, how could they possibly withstand the power of lightning?

The remaining pirates were all dumbfounded, and some, like Mohji and his lion Richie, directly hid at the back of the crowd.

Wasn't Kaminari supposed to be the weakest and most useless on the ship? Where did he obtain such formidable strength?

Who is this guy?

Just as everyone was filled with confusion, Kaminari spoke, "Is there anyone else who dares to challenge me? I'm here waiting."

As soon as these words were spoken, no one dared to take a step forward.

Even the two strongest people on the ship, Buggy and Cabaji, had been taken down. The remaining lackeys didn't dare to provoke this bad luck.

They were originally a group of bullies who picked on the weak and feared the strong. They could get away with bullying civilians, but when they saw the crackling lightning surrounding Kaminari, they realized that this level of power was beyond their capability to handle.

They were just trying to make a living on the ship; there was no need to sacrifice their lives for a captain who was nothing more than a clown.

Instead of moving forward, the crowd involuntarily stepped back, creating a space.

Don't despise a sick child, for he might be a tiger cub.

Don't bully a poor young man.

Why provoke a sleeping lion?

Seeing that no one dared to resist anymore, Kaminari slowly walked towards the ship...

He boarded Buggy's ship, raised the sails, and sailed alone towards the sea.

The crowd still dared not speak, silently watching as Kaminari sailed the ship away...

Kaminari was originally captured and brought onto this ship, and the events that unfolded on the ship made him have no attachment to the Buggy Pirates.

Moreover, it wasn't that he didn't want to annihilate the Buggy Pirates earlier, but his chakra reserves were running dangerously low.

The first time he infused chakra into his fist and attacked Cabaji, it cost him 10 points of chakra. Then, using the Chidori Stream depleted another 80 points. Now, Kaminari's chakra value was reduced to 10 out of 100.

In other words, if the pirates had swarmed him just now, his life would truly have been in danger.

Kaminari's boldness saved his own life. He intimidated the group of bullies who feared the strong.

He had to become stronger.

And so, Kaminari embarked on his adventure, gazing at the azure sea, feeling his heart surge with excitement.

He made a firm decision: to become the strongest and freest person on this vast ocean.

The first thing he did on the ship was to take down the ridiculous clown pirate flag.

Not only was he no longer a member of the Buggy Pirates, he wasn't even a pirate anymore.

Next, Kaminari contemplated his identity and position.

Pirate? Marine? Bounty Hunter? Revolutionary Army? Adventurer?

He made his choice without hesitation.

Bounty Hunter.

Because, at this stage, if he wanted to become stronger, he needed a large amount of funds to draw cards and obtain ninjutsu to increase his chakra reserves. Hunting pirates and earning bounties with his current strength was undoubtedly the best method.

While Kaminari was contemplating these thoughts, the system sent a notification.

[ Friendly reminder: You can increase your chakra limit through self-cultivation and create your ninjutsu. ]

With just this simple sentence, Kaminari suddenly had a realization.

He smacked his forehead and thought to himself, "Right, since I have a chakra value, in a certain sense, I can consider myself a ninja. And if I have chakra, then I can train and cultivate myself like the ninjas in Naruto."

Kaminari pondered for a moment about the explanation of chakra. According to the original Naruto manga, chakra is the physical energy absorbed from the 130 trillion cells within the human body, as well as the spiritual energy honed through training and accumulated experience. Additionally, there is a portion of chakra that comes from natural energy when practicing ninjutsu.

Now, Kaminari didn't even have half a beli on him, so he couldn't draw ninjutsu at all. In that case, self-cultivation was undoubtedly the best method.

Just like when he infused chakra into his fist and attacked Cabaji earlier, it was the simplest form of attack.

The first technique that came to Kaminari's mind was the S-rank ninjutsu of the ANBU Commander of Konoha, Hatake Kakashi's father, Hatake Sakumo—White Light Chakra Sabre.

The name of Hatake Sakumo was almost universally known. He was Kakashi's father, known as the "White Fang of the Leaf," and even the legendary Sannin held him in high regard.

Hatake Sakumo's technique, the White Light Chakra Sabre, utilized the chakra released from his short sword, White Fang, which surged like lightning at almost the speed of the Flying Thunder God Technique to attack enemies, earning him his nickname.

Why did Kaminari think of this technique?

He wanted to use it as a basis to create his ninjutsu.

He found a wooden board, gathered chakra in his right hand's middle finger and index finger, and slashed it across the board. As a result, the board only bore a mark resembling a knife's slash.

This move was just an imitation and couldn't be compared to Hatake Sakumo's S-rank White Light Chakra Sabre.

"Is it still not sharp enough? If I were to combine it with a sword, the effect of this technique should be better, right?" Kaminari scratched his head, muttering to himself.

Afterward, he followed the same method as before and practiced this bootleg version of the "White Fang Technique" over and over again.

Several hours later, Kaminari was drenched in sweat, his physical strength almost depleted. His chakra value had dwindled to 2 out of 100, nearing its limit.

As a result, he immediately searched for food on the ship and headed to the refrigeration room in the cabin. Inside, there were some leftover sea creature meat, fruits, and vegetables. After cooking them, he enjoyed a satisfying meal.

Back when he was a low-level shipworker, this was something he couldn't even dream of. He couldn't even afford a proper meal. But now, things were different. He was the owner of this ship, free to do as he pleased.

It was all attained through his strength.

In this manner, he ate, slept, and trained on the ship. After two days, the ship gradually approached an island.

It was an uninhabited island. Kaminari disembarked and saw lush vegetation covering the island, almost like a small forest. Islands like this were common in the world of One Piece, and adventurers would usually take the opportunity to rest and recuperate on such islands.

However, Kaminari had a different idea. The space on the ship was limited, but here, the air was fresh, making it a good place for cultivation. Besides, he might encounter something he hadn't seen before on the island.

Not wanting to waste any time, Kaminari continued his training under a large tree.

After practicing the imitation of the White Light Chakra Sabre for these two days, Kaminari estimated that he had reached the current limit of his proficiency with the technique. After all, his chakra was extremely limited.

Therefore, Kaminari decided to practice a new ninjutsu: the Rasengan.
