Luck

Rasengan was a ninjutsu frequently used by the protagonist of Naruto, Naruto Uzumaki. Inspired by the Tailed Beast Bomb, the Fourth Hokage, Minato Namikaze, spent three years developing it. His son, Naruto, later carried it forward and enhanced it.

Its principle was the same as the Tailed Beast Bomb's: chakra was struck together and condensed into a small sphere to attack the opponent. Once it hit an enemy, it could not only cause damage but also throw their chakra into temporary disarray.

For Leiyin, the greatest advantage of this ninjutsu was that it could be learned without forming hand seals.

Its essence was to condense chakra in the hand, make it flow continuously in different directions, and compress it, forming a chakra sphere with a rotating density.

Afterward, elemental chakra could also be infused into it. For example, wind-nature chakra could form the [Wind Release—Spiraling Shuriken], creating even greater destructive power. However, that was a story for later.

Leiyin then practiced according to the method Jiraiya had used to teach Naruto in the original Naruto story.

He gathered chakra in his hand, making it form a sphere, then made the chakra flow rapidly in different directions.

The result was obvious.

Let alone forming a Rasengan, Leiyin found that even creating a chakra sphere was extremely difficult.

He could not help asking the Naruto System, which gave him a reasonable explanation.

"First, your ability to control chakra is still very weak. Second, activating even the most ordinary Rasengan requires 200 points of chakra, while your current limit is only 100."

Leiyin immediately understood. To activate this ninjutsu, he first needed to learn to control chakra properly. As for his chakra quantity, it would definitely increase in the future.

Based on his memories of the original story, there were generally two methods for learning to control chakra well. One was gathering chakra in his feet and climbing trees. The second was also gathering chakra in his feet and walking on water.

However, there was sea everywhere here, so Leiyin chose the second training method without hesitation.

He soon found a shallow stretch of sea near the island, where the water barely reached his knees. He gathered chakra in the soles of his feet and cautiously stepped onto it.

The result was that as soon as Leiyin put his foot down, he immediately sank to the seabed. Fortunately, the water was not deep, and only the lower part of his trousers got wet.

However, this was merely the beginning. He continued practicing over and over again.

After about an hour, Leiyin could already stagger across the surface of the sea.

For an ordinary person, this training speed was already extremely fast. Leiyin also knew that this was not something that could be achieved overnight. Moreover, after this training, he had almost exhausted his chakra. Thus, he returned to the ship, took food from the cold storage, ate a meal, and then took an afternoon nap to restore his strength.

When he woke up, Leiyin felt refreshed and completely at ease. His chakra had also fully recovered.

He once again headed toward the shallow sea.

However, a huge creature blocked his path in the forest.

It was a lion more than six meters long with two tails. The two fangs beneath its lips were more than twenty centimeters long, sharp as blades.

At that moment, it was glaring at Leiyin menacingly, looking as though it might pounce at any time. Its gaze was far sharper than that of Moji's lion, Riki, and its strength was probably more than several times Riki's.

Only later did Leiyin learn that this type of lion was called a Two-Tailed Saber-Toothed Lion. It was ferocious and cruel by nature. The moment it saw a living creature, it would hunt and attack without hesitation. And if it grew hungry enough, it would even eat its own kind.

Judging from the saber-toothed lion's appearance, it had probably gone several days without eating. When it saw Leiyin, drool dripped from the corners of its mouth, and its eyes were bloodshot.

Faced with such a vicious creature, its savage, terrifying gaze made ordinary people lose their wits in fear upon seeing it. They would not even dare to move.

Leiyin merely scratched his head indifferently. "This really is the world of the Pirate King. I've never seen such a rare and exotic beast before."

Hearing Leiyin's words, the saber-toothed lion felt that he was provoking it. It already had a foul temper, and his words only further inflamed its fury.

The next moment, the saber-toothed lion let out a roar, whipping up a fierce gale as it charged toward Leiyin.

Leiyin sidestepped to evade its attack, then released his chakra. Blinding lightning began flashing across his body...

Lightning Release—Chidoryū!

Wrapped in flashing lightning, he charged toward the saber-toothed lion. The lion was struck by the lightning and immediately convulsed all over. Before long, charred black marks appeared across its body, and amid its agonized howls, its enormous body suddenly collapsed to the ground.

It was a completely one-sided victory. The lion lying on the ground no longer showed any sign of life.

At that moment, the lion's slightly charred corpse still emitted waves of meaty aroma. This was caused by the high-temperature attack produced by the lightning release.

Looking at the huge creature he had killed in an instant, Leiyin scratched his head. "Perfect. I'm out of food on the ship anyway, so you can be my dinner. I just don't know whether you'll taste good. But judging by the smell, you should be pretty tasty..."

By then, night was approaching. Leiyin carried the lion back to his ship, cooked the meat, which had already been half-cooked, a little more, and began eating with relish.

"Mmm, it really does taste pretty good..."

He sat alone at the dining table, holding a knife and fork as he enthusiastically chewed on chunks of meat, amusing himself.

In his previous life, aside from loving anime, Leiyin had also loved good food. He was a seasoned foodie. As long as he could eat something delicious, he would be overjoyed.

After eating and drinking his fill, with dishes and cups strewn everywhere, Leiyin went to sleep...

The next day, just as the sky began to brighten, Leiyin woke up. For some reason, he felt that his physical strength had increased greatly, as though his body were filled with tremendous power.

At that moment, the system issued a notification: Your chakra limit has reached 300. Current chakra: 300/300.

Huh? Why was this happening?

The system explained: The lion you ate yesterday was a spirit lion. In the world of the Pirate King, Two-Tailed Saber-Toothed Lions are extremely rare. Eating their meat activates the cells, strengthens the body's immunity, and increases physical strength. In this Naruto System, this manifested as a dramatic increase in chakra.

Not only that, but the experience accumulated through your training over the past few days had also increased your chakra.

So that was how it was. While marveling at his good luck, Leiyin could not help feeling exhilarated. If this continued, I would be getting closer and closer to becoming a "strong fighter"...
