While Nami is still young, invite her to join my ship!

Looking at the smirk on Ningchuan's face.

Koshiro was so angry at his words that he almost fell to the ground!

"Don't you know how to take a break, you bastard?"

"You just finished learning my swordsmanship, and you want to start learning my family's sword-making?"

"Even if you want to fleece the sheep, you have to slow down and give the sheep some time to grow wool!"

"What do you mean? Are you so anxious to kidnap my baby?"

Looking at the furious Koshiro, Ningchuan had to shake his head helplessly, feeling a little disappointed.

"It seems that I can't learn sword-making today!"

"I don't know when Koshiro will calm down, I just hope he can be faster!"

"Otherwise, I'm afraid I won't be able to catch up with the excitement in the East China Sea!"

Just as Ningchuan was about to end today's practice and take a good rest.

Waiting for Koshiro's anger to dissipate a little, he would mention the matter of learning sword-making.

However, just as he said goodbye to Koshiro and was about to leave the gym,

Koshiro's voice reached his ears at this time.

"Tomorrow at 4 a.m., the old man will open a furnace in the back mountain to practice a batch of swords!"

"If you are interested, you can come and see!"

...

The port of Shimotsuki Village.

Kuina has come to Ningchuan's boat.

The sensible Nami has taken out the paintbrush.

Start to add Kuina's head portrait to the flag hanging on the boat.

"Okay! There will be four of us on this ship from now on!"

Looking at the painted Kuina as a head portrait, Nami hugged her hands in front of her chest and looked very happy.

Kuina looked at her big head portrait on the flag and couldn't help smiling.

However, as she smiled, she began to worry about Ningchuan.

She was afraid that he would not pass the test of her father.

After all, her hateful father only gave Ningchuan one day to practice.

One day is definitely not enough for a swordsman to practice!

Nokigo seemed to see Kuina's thoughts.

He reached out and rubbed Gulina's head, smiling and comforting.

"Don't worry!"

"Things that are difficult for ordinary people are not that difficult for Ningchuan!"

"His training speed even shocked the navy hero Vice Admiral Garp!"

After Nokigo finished speaking, Kuina's face showed a very shocked look.

"Vice Admiral Garp?"

"Is it the navy hero who captured the Pirate King Roger?"

In the East China Sea, when Vice Admiral Garp's name is mentioned.

Almost no one does not admire him!

Of course, except for pirates...

"You guys are chatting happily!"

Ningchuan's figure flashed and landed directly on the deck of the boat.

Looking at Ningchuan who had returned to the boat so quickly.

Nami and Nokigo both showed a hint of happiness on their faces.

They were familiar with Ningchuan's character and knew it.

Ningchuan was able to return to the boat so quickly, which meant that he had completed Mr. Koshiro's requirements!

But Kuina frowned as she looked at Ningchuan who suddenly appeared here.

"Ningchuan, have you successfully mastered my father's swordsmanship?"

Kuina asked with a tone of disbelief.

Looking at Kuina with a worried look on her face.

Ningchuan smiled and pulled out the wooden sword brought out from the gym's power from his arms, pointed the sword tip to the sea, and chuckled.

"You'll know if it works after a try!"

After saying that, Ningchuan's mouth corners slightly raised.

At this moment, he summoned all the armed color domineering in his body and covered it on the wooden sword in his hand.

He took a deep breath, and the momentum around him suddenly climbed to the peak!

The powerful aura instantly shocked Nami, Nokigo and Kuina.

They were all stunned in place, their eyes wide open, staring at Ningchuan's next move.

His momentum has reached the extreme!

Ning Chuan no longer held back, aimed at the vast sea in front of him, and fiercely slashed his sword down!

With the flash of the sword, the sound of the long sword breaking through the air was sharp and piercing.

At this moment, it seemed that even the passage of time had slowed down a lot.

In the shocked eyes of the three people.

The originally turbulent sea surface a hundred meters in front of the boat was actually split in two by Ning Chuan's sword!

The sea water on both sides was like being cut by an invisible blade, revealing a secret passage leading directly to the seabed!

This process lasted for five minutes.

Until Ning Chuan's sword intent dissipated completely, the sea that was split in two slowly healed together.

"Bang!"

Just when the three women were shocked by Ning Chuan's sword and widened their eyes, unable to say a word.

A crisp explosion sounded in the ears of the three people..

They looked back and saw that the wooden sword that could cut the sea just now.

At this moment, it had exploded and turned into a pile of sawdust.

"What a pity, this sword really can't withstand my domineering power."

"If there is a supreme big knife, the power of this move will at least be several times greater!"

Ningchuan sighed helplessly and blew away all the sawdust in his hand.

However, there was no regret on Ningchuan's face at this time.

Because he knew that he should be able to get the supreme big knife tomorrow!

...

Time passed quickly.

In the early morning of the next day.

When Nami and Nokiko were still asleep.

Ningchuan came to the back mountain of the island at the agreed time to see the place where the Shimotsuki family forged swords.

The one who presided over the family's sword forging affairs was Kosaburo, the father of Koshiro.

Kosaburo was a sword forging master who had forged two famous swords!

And they are all famous swords of the great sword level, and there are only twenty-one of this level of famous swords in the world!

One is the Wado Ichimonji that Zoro has been carrying in the original plot.

The other is the Enma that Zoro later held in Wano Country!

These two famous great swords are all from Kozaburo!

This shows how powerful he is in sword-making technology!

But it's a pity.

Since Kozaburo led his family to leave Wano Country and successfully lived in seclusion in the East China Sea.

Except for a Wado Ichimonji, he has never been able to forge a famous sword of the great sword level!

With Ningchuan's footsteps, he landed steadily in front of a small house that looked quite dilapidated deep in the mountains.

An old man with white beard and eyebrows came out of the house with a pipe in his mouth.

After looking Ningchuan up and down seriously, he finally spoke.

"The sword spirit is restrained and not scattered! If you don't feel it carefully, it's hard to realize that you are actually a swordsman!"

"Not bad, interesting!"

"You should be Ningchuan mentioned by Koshiro yesterday?"

Hearing the old man mention his name.

Ningchuan nodded seriously.

"Hello, Senior Koshiro!"

"I came here this time to learn sword forging from you!"

"I want to make a few supreme big swords!"

As soon as Ningchuan finished speaking, Koshiro couldn't help laughing.

"Hahaha!"

"You kid, you are really as arrogant as Koshiro said, I like it!"

"There are only twelve supreme big swords in the world, and you want to make several of them?"

"Young man, you are so greedy!"

After listening to Koshiro's evaluation of himself being too greedy.

Ningchuan just smiled faintly and didn't say much.

After all, he has a ten thousand times cultivation return system, which ordinary people cannot understand!

"Yes, you are confident enough!"

"Otherwise, it would be impossible to reach the realm of swordsmanship in such a short time!"

"With your qualifications in swordsmanship, sword forging is definitely enough!"

At this point, Kozaburo suddenly looked at Ningchuan with a smirk and said.

"However, the sword forging technique of my Shimotsuki family is a family heirloom, and is generally not passed on to outsiders!"

"So... when will you marry Kuina?"
