[OP]Chapter 8: Luck

The Rasengan is a commonly used ninjutsu technique by the protagonist of Naruto, Uzumaki Naruto. It was developed by the Fourth Hokage, Namikaze Minato, inspired by the Tailed Beast Ball, and took him three years to create. His son, Naruto, further perfected it.

The principle of the Rasengan is similar to that of the Tailed Beast Ball. It involves striking chakra and condensing it into a small sphere to attack the opponent. Once it hits the enemy, it not only causes damage but also disrupts their chakra temporarily.

For Kaminari, the biggest advantage of this ninjutsu is that it doesn't require hand seals to learn.

Its essence lies in gathering chakra in the hand, continuously flowing it in different directions while compressing it to create a rotating and dense chakra sphere.

Furthermore, it is possible to infuse elemental chakra into it. For example, infusing wind chakra creates the "Wind Release: Rasengan," resulting in even greater destructive power. However, that's a story for later.

Kaminari then practiced using the methods taught to Naruto by Jiraiya, as described in the original Naruto series.

He gathered chakra in his hand, forming it into a sphere, and then made the chakra flow rapidly in different directions.

The results were evident.

Not only was Kaminari having difficulty forming the Rasengan, but he even struggled to form a simple chakra sphere.

He couldn't help but ask the system for an explanation, and the system provided a reasonable response.

[ "Firstly, your ability to control chakra is still weak. Secondly, launching a basic Rasengan requires 200 units of chakra, while your current limit is only 100." ]

Kaminari immediately understood that to use this ninjutsu, he first needed to learn how to control the chakra effectively. As for the chakra capacity, it will increase in the future.

Based on his memories of the original series, there were roughly two methods to gain better control of chakra. One was to gather chakra in the feet to climb trees, and the other was to concentrate chakra on the soles of the feet to walk on water.

However, since the area was surrounded by the sea, Kaminari decisively chose the second training method.

He found a spot near the island where the water was knee-deep and gathered chakra on the soles of his feet. Carefully, he stepped onto the water's surface.

The result was that as soon as he stepped on it, he instantly sank to the seabed. Fortunately, the water wasn't deep, and only his lower legs got wet.

But this was just the beginning, and he continued to practice repeatedly.

After about an hour passed, Kaminari was able to walk unsteadily on the water's surface.

For an ordinary person, this training speed was already considered fast. He knew that it was not an overnight achievement, and after such training, his chakra reserves were almost depleted. So, he returned to the ship, took out the food from the refrigeration room, had a meal, and then took a nap to replenish his energy.

Upon waking up, Kaminari felt refreshed and energized, and his chakra had fully recovered.

Thus, he once again headed towards that shallow sea.

However, his path was blocked by a large creature in the forest.

It was a lion-like creature, over six meters long, with two tails and two fangs under its lips, each measuring more than twenty centimeters in length, as sharp as knives.

At this moment, it was glaring at Kaminari, ready to pounce at any moment. The gaze of this lion, compared to Mohji's lion Richie, was much sharper, and its strength was estimated to be several times greater than Richie's.

Later, Kaminari learned that this type of lion was called the Double-Tailed Swordtooth Lion. It was naturally ferocious, attacking and hunting any living creature without hesitation. Not to mention living creatures, if it was extremely hungry, it would even eat its kind.

Judging from the appearance of the Swordtooth Lion, it seemed that it hadn't eaten anything for several days. When it saw Kaminari, drool dripped from the corners of its mouth, and its eyes were bloodshot.

Faced with such a wicked and ferocious creature, with its terrifying gaze that seemed to devour people, an ordinary person would have been scared out of their wits and wouldn't even dare to move.

Kaminari, on the other hand, casually scratched his head and said, "It's truly the world of One Piece. I haven't seen such rare and exotic beasts before."

Hearing his words, the Swordtooth Lion felt provoked. It already had a bad temper, and now its anger was further ignited...

Immediately, the Swordtooth Lion roared, causing a gust of wind to sweep through as it pounced towards Kaminari...

Kaminari swiftly dodged its attack and then released his chakra, causing his body to flicker with dazzling lightning...

'Raiton - Chidori Stream!'

With his entire body sparkling with lightning, Kaminari fiercely rushed toward the Swordtooth Lion. The lion was struck by the lightning, convulsing in pain. Before long, its body was charred, and it let out a mournful howl as its massive body collapsed to the ground.

It was a complete one-sided victory, and the lion lying on the ground no longer showed any signs of life.

At this moment, the slightly charred body of the lion emitted a tantalizing aroma of meat, caused by the high-temperature attack of the Chidori.

Looking at the large creature he had just killed, Kaminari couldn't help but scratch his head. "Well, since there's no food on my ship anyway, you can be my dinner. I wonder if you'll taste good. But judging by the smell, it should be delicious..."

By now, it was getting late, and Kaminari carried the lion onto his ship. He cooked the already partially cooked meat a bit more and enjoyed a satisfying meal.

"Mmm, the taste is really good..."

He sat alone at the dining table, holding a knife and fork, chewing the chunks of meat with delight.

In his previous life, besides being an anime enthusiast, he was also a big foodie. Anything delicious could bring him immense joy.

After filling his belly and creating a mess of plates and utensils, Kaminari went to sleep...

The next day, as the sky began to lighten, Kaminari woke up from his slumber. For some reason, he felt a surge of energy, as if he had gained the strength of a thousand pounds.

At that moment, the system sent a notification: [ Your chakra limit has reached 300, and your current chakra level is 300/300. ]

'Huh? Why is that?'

The system explained: [ The lion you consumed yesterday was a Spirit Lion. In the world of One Piece, the Double-Tailed Swordtooth Lion is quite rare. If its meat is eaten, it activates the cells, enhances the body's immune system, and increases physical strength. In the context of this Naruto system, it manifests as a significant increase in chakra.

Not only that, but your chakra has also increased due to the accumulated experience from your training in recent days. ]

'So that's how it is.' Marveling at his good fortune, Kaminari couldn't help but feel exhilarated. With this, he was getting closer and closer to becoming the "strongest."
