As a pirate, he wants to be the king but relies on his son to conquer the world.

Koushiro smiled and said: "As far as I know, there are three ways for a swordsman to break through a great swordsman.

The first is to continue to deepen the breath of all things. If the swordsman is Zhan Gang, then the great swordsman. It can cut through materials that are much harder than steel, such as diamonds. This requires the swordsman to further deepen the breathing of all things. As for how to be considered a great swordsman. Usually, the armed color Haki is practiced into the sword, turning it into a black sword. Most swordsmen follow this path.

There are also some swordsmen who take the path of artistic conception. Not only swordsmen, but also those who use guns, hammers, and fists will understand the artistic conception. Combining artistic conception and swordsmanship can also defeat the great swordsman.

The last method is to find a suitable knife, usually a supremely fast knife, or to cast a knife yourself to match it. ”

Sparrow thought for a moment.

Isn't the first method just to cut, cut, cut, cut all the way, and defeat all methods with one sword?

The second kind is more like the artistic conception in martial arts novels. The fist has the intention of the fist, and the sword has the intention of the sword. Rather than using the sword, it is better to use the sword to express one's artistic conception. One sword creates all kinds of magic? The Bista in the white group seems to have flower petals flying when the sword is drawn.

What's the last one? Can man and sword become one? Wouldn't it mean that without the sword, he would no longer be a great swordsman? If you encounter a stronger sword, such as a demon sword, a ghost sword, etc., should a person control the sword, or should the sword control a person?

Sparrow shook his head slightly, then looked at Koushiro and said:

"The owner of the museum is really hiding his secrets. It's a pity that he is in this partial place in the East China Sea."

Facing Sparrow's probing and discovery, Koushiro didn't mind and just shook his head slightly.

"It's no pity. Nowadays, we are partial to one side here. It's pretty good. At least it's peaceful and quiet."

Sparrow shook his head slightly and looked at Kuina waving in the courtyard.

"Then let's make a bet about Kuina!"

Koushiro frowned slightly at Sparrow's abrupt mention of Kuina.

"What's the explanation?"

"The museum owner should understand that your daughter has talents. Although you don't want her to get involved in the world's conflicts, some things are unavoidable in this world."

"Why not have strength at your disposal to protect yourself, others, and things, so that you won't regret it."

Koushiro was speechless for a while, looked deeply at Sparrow, and pondered for a long time.

"I didn't expect that even though you are young, your views on things are very clear. I am blind."

Koushiro looked at Koina who was wielding the sword very seriously and sighed slightly.

"I'll take this bet!"

Sparrow nodded slightly, the two of them were silent, and the atmosphere was quite peaceful.

Kuina, who returned, came to Sparrow as if she had made a new discovery.

"Hey! Tell me more about kendo."

After hearing Kuina's words, Sparrow smiled freely and said to Koushiro.

"Hahaha! Owner, what do you think?"

Koushiro shook his head slightly and looked at Kuina with relief, but the corners of his mouth were slightly raised.

"Failed, defeated!"

Guina looked at the two strange people inexplicably, completely confused.

"Father, did you say something that I don't know?"

"Kuina!" Koushiro looked at her deeply, and then said: "I hope you can become the first female great swordsman in the world one day."

Guina was stunned by this sentence. How sudden the surprise came. This sentence was not abrupt at all.

She didn't expect that one day she would hear words of encouragement from her father, which she couldn't believe.

He wanted to confirm with a trembling tone.

"Father, you just..."

"Guina, my daughter, I hope you will become a world-famous swordsman one day!"

Koushiro said it again very seriously, which made Kuina's eyes turn red and she began to feel hazy.

With a clang, he threw the sword away and threw himself directly into Koushiro's arms, whimpering and crying.

The more determined a person is, the weaker he appears after breaking down the barriers.

Kuina is also such a person. She has been tough since she was a child, but is actually very fragile.

After Kuina stabilized her mood, Koushiro wiped away her tears, but Kuina was a little embarrassed.

"Thank you for your persuasion. I will do my best to teach my little girl."

Sparrow waved his hand and joked slightly: "Okay, if you have a chance, come to Rogge Town to find me, and I can help her."

Kuina, who had reddish eyes, nodded very seriously, leaving Sparrow speechless.

"In that case, let me give you something, just as a token."

He took out a hairband from behind and handed it to Kuina.

"As a female swordsman, you need to keep your hair well restrained. Let me use this for you!"

This was naturally designed to prevent Guina from falling on her head and dying. Guina has always been a pity.

Although Guina looked a little contorted when she saw her wearing a hairband with joy, she coughed a few times and still praised her against her will.

"Well, it's beautiful."

"This time I have gained a lot. I will definitely be able to break through the Great Swordsman in a few years.

Without the guidance of Master Koshiro, I might still be struggling with how to combine the artistic conception with the breathing of all things.

The day when he can break through to become a great swordsman may still be delayed for a few more years. thank you very much. ”

With that said, Sparrow took out the secret book-Crystal Meditation Technique that he had already written from his arms and placed it on the table.

Sparrow felt a little emotional: "In 1498, I witnessed the death of the Pirate King Roger with my own eyes. His words shocked the entire sea. At that time, I was also thinking about going to sea. However, when I was young, my physical fitness and talent were not the same. It's not very good, and I can't even say the hardest working. At the age of 14, I'm afraid I can't even compare to your current daughter. I didn't even pass the recruit test when I interviewed for the Navy, so I could only be a miscellaneous soldier. In anger, I ran to Baiyun Gym, learned swordsmanship for half a year.

It wasn't until after eating the Devil Fruit that I relied on the Devil Fruit's ability to become a superman with 500 strength points in the navy!

Over the years, I have been thinking about how to improve the efficiency, time, and effectiveness of practice.

This is the first practice I created, called Crystal Meditation.

It helps a person enter a state of what I call deep sleep.

Studies have shown that one hour of deep sleep for humans is much better than seven or eight hours of light sleep for ordinary people.

If you sleep less than seven hours a day, how much time can you save to study and do things?

The effect of one hour of deep sleep can make people feel energetic all day long and have excellent memory. Over time, the body will be strong and life will be prolonged.

The effect on you may be small, but it must be extremely suitable for laying the foundation for your daughter. ”

Eat well, train well, and sleep well. So fast step by step. I wish your daughter can reach the level of a great swordsman soon. ”

Koushiro did not refuse and stood up to see Sparrow off.

"Then Master Koushiro and Kuina, the purpose of this trip has been achieved, so I will take my leave."

Arriving at the entrance of the dojo, saying goodbye to the two of them, Sparrow left.
