In Kuro's eyes, the matter of Misaki and her father was a trivial matter. As long as they didn't reveal the truth about the pure gold, there wouldn't be any problem.

They lived for two hundred years longer. Although they were inside the belly of a lanternfish, there was no one to talk to and no social environment to help them grow, it was still two hundred years. That's a long time, enough to understand a lot of things.

They suffered two hundred years of lonely tragedy precisely because they were pure gold, and they knew very well what to do next.

He has already sent the pure gold to the sky, and the lanternfish is too scared to come over. It can just wander in the deep sea with the remaining pure gold.

That kind of enormous size is extremely difficult to deal with.

Even Kuro couldn't guarantee 100% that he could definitely defeat it.

Fortunately, he had seen fear in the lanternfish's eyes, so he was certain it wouldn't come anytime soon. Besides, this lanternfish only wanted the pure gold luster; it wasn't bloodthirsty or vengeful. Without the pure gold luster, it wouldn't deliberately surface, and therefore wouldn't reappear.

That's the end of it.

With the help of Kro, Mischina and her father soon landed on Meng Island. This world did not have a household registration system, and Kro's help was simply to forge evidence of their life there.

After all, the navy took over the island, so they have that kind of authority.

After settling down, Kuro stopped caring about anything else; he had his own things to do.

A few days later, on the cliff behind the naval base.

The waves crashed against the reefs and cliffs, creating a rushing sound. Over countless years, the sharp edges of the rocks and cliffs have been worn smooth by the water.

Such a rock wall is impossible for ordinary people to climb, and it is also very high, so ordinary pirates would not be able to launch a surprise attack from this direction.

Otherwise, why would natural harbors be so sought after? Some naturally formed harbors are designed to block enemy attacks, like places like Meng Island.

Beside the cliff, Kuro stood with his eyes closed, in an iaido stance, completely still.

Wow!

The waves crashed against the rocks, creating a loud roar, and at the same time, a black light flashed past him with incredible speed.

The black light disappeared, and so did the sound of the waves.

Wow!

brush!

The waves crashed out again, and the black light rose once more, swirling around Kuro.

"Kuro, Ku..."

Lida ran over from a distance, but when she saw him like this, she immediately shut her mouth.

There were several other people with her.

Kro, Sazir, and a blonde little girl all came over.

Mischina Olga, who claims to be 206 years old and whose real age is also 206, but whose mental age is estimated to be only seven or eight years old.

She ended up hanging out with Lida.

One is Lida, who, although she is eighteen years old, has lacked proper interpersonal relationships due to her long-term foraging and fear of being discovered, resulting in a psychological age that is more in line with her current physique.

Olga, who, despite being an "ageless old woman," was not affected by her environment and thus only grew in age but not in physical growth, was an exception.

The two of them got along very well and became friends in just a few days.

Olga, in particular, quite likes to eat it.

For two hundred years, she only ate the fish inside the bellies of lanternfish and such; she was very interested in proper gourmet food.

They teamed up perfectly with Lida, and spent their days exploring and eating on Moe Island.

"Hey! What's that for? That black light... what is that thing?" Olga asked in surprise.

With her eyesight, all she could see was Kuro standing there, gripping the sword at his waist, motionless.

"The flash of a blade."

But what Lida saw was different. She could see Kuro draw his sword. It wasn't a still figure; Kuro drew his sword extremely quickly, slashed forward, and then immediately sheathed it.

And Kro could also sense this.

Kuro pushed up his glasses. "It's rare to see Mr. Kuro practicing; I should observe him closely."

His current signature move, 'Shave,' is derived from a technique by Kuro. If you can discern anything from it, it will definitely help his strength.

"Was there really a sword swing? I couldn't see it at all."

Sazir swallowed hard. Although he had some strength, like Olga, he couldn't see Kuro's sword-wielding movements clearly at all. However, he keenly noticed something was wrong.

"Swing your sword based on the sound of the waves crashing? What's the point of that?"

"Just watch quietly. You haven't reached that level yet."

Kro gave him a disdainful look.

Although he couldn't understand it either.

But Mr. Kuro must have had a deeper meaning in doing this. Swinging his sword in rhythm with the waves might be a technique that reflects his understanding of the natural world.

"Based on the sound of the waves crashing?"

Lida said, "It's clearly him swinging his sword that stirred up the waves. Kuro swings his sword once, and the waves only hit once. Don't get it backwards."

“That’s right, exactly.” Kro nodded emphatically.

Fortunately, he didn't say it out loud, otherwise he would have been incredibly embarrassed and disgraced as the strategist by Kuro's side.

brush!

Wow!

Kuro's sword flashed again, and the waves crashed against the reefs and cliffs at just the right moment. Only then did he open his eyes and exhale through his nose.

"Tsk, it really is a bottleneck in swordsmanship. It's too slow to practice."

Kuro released his hand from the hilt of the sword, stood up, and said with some annoyance.

Compared to physical skills, he should definitely try swordsmanship first, since that is the foundation of his career. But at his age, further progress is no longer comparable to simply carving mountains.

Kuro's swordsmanship progress actually involved two steps.

The first step was to carve out the mountains back then. Once he had done so, his swordsmanship reached a bottleneck.

The second step is to face nature and experience it firsthand, reaching another level by wielding the sword in harmony with nature.

The former is Karp's training method, while the latter is another method he found after hitting a bottleneck.

The training method comes from Hunter x Hunter [Netero], but it has now reached a bottleneck. Although there is still growth, the progress is extremely slow, to the point that it takes several years to grow even a little bit.

The swordsmanship itself is already at a high level.

Whether it's the domineering way of using it or the creation of new sword techniques, it's all within the "water tank" of his sword techniques. At most, it's like adding water, not increasing the volume of the "water tank".

To increase the size of the [water tank], you either need to find a more efficient method or learn through continuous battles.

Kuro immediately rejected the latter, saying he didn't want to fight and just wanted to coast through life. As for the former, he could only wait for himself to figure it out.

ha?

Saitama's training methods?

You think you can mess with me?

He had already tried that thing when he transmigrated. In fact, he didn't have Saitama's powerful idealism or training methods. He couldn't even keep up with the training level of the Marine Headquarters.
