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

Watching Ning Chuan holding a sword blank of ordinary iron grade and stepping into the sword casting room.

Geng Sanlang's mouth corners tilted, and he smiled in his heart.

"You are a little self-aware, and you didn't waste the good sword blanks that I worked hard to save."

"With an ordinary iron grade sword blank, I want to see what level of sword you can make!"

Feeling the fiery breath of iron and fire in the air.

Ning Chuan carried the sword blank in his hand and came to another casting table next to Geng Sanlang.

Standing on the workbench made of special materials, looking at the boiling magma below.

Ning Chuan couldn't help but admire in his heart.

"Keng Sanlang is worthy of being a sword casting master. He can use the power of nature so cleverly to cast swords!"

"Dong!"

Just when Ning Chuan was admiring Geng Sanlang for finding such a good place to practice swords.

Suddenly a dull sound attracted his attention.

"Watch out, Ningchuan!"

Kozaburo's voice was steady and powerful, and the sledgehammer in his hand landed accurately on the sword blank on the workbench!

Every time he struck, a lot of sparks flew out.

"Forging is the soul of sword-making!"

"A good sword must be forged with thousands of hammers, from the tip to the blade to the blade, from thick to thin, from soft to hard!"

"The strength of every part of a sword must be just right, not too much or too little, not too heavy or too light, only in this way can a good sword be made!"

Ningchuan stared at Kozaburo's extremely focused face.

He nodded silently in his heart and kept his words in mind.

Looking at the serious look on Ningchuan's face, Kozaburo continued to speak.

"To master this delicate balance and apply the most appropriate force to each part of the sword, it will take at least several years or even decades to master it!"

"However, for those who are good at using swords and understand swords, this time may be shortened a lot!"

At this point, Kosaburo changed the subject and continued with a smile on his face.

"So, if a swordsman learns to forge a sword, it will be much easier than for simple blacksmiths!"

"You, kid, have become a swordsman at such a young age. It is because of your talent in kendo that I am willing to teach you to forge a sword!"

"Next, I will start forging, don't blink at me, kid!"

"Otherwise, if you miss this time, I won't show you how to forge slowly in the future!"

After that.

Kosaburo directly picked up an iron hammer and covered it with armed color domineering.

Insert the sword embryo deeply into the magma, wait until it burns red, raise the hammer and start forging!

"Hit hard here!"

"Hit lightly here!"

"The speed and strength must be even here!"

...

Although Kosaburo was going to demonstrate it to Ningchuan slowly,

In fact, his speed was not slow, and the hammer in his hand was about to fly out of sparks.

However, under Ningchuan's top-level observation Haki,

He still watched Kosaburo's forging process carefully from all directions!

Three hours later, Kosaburo's first forging finally stopped.

And Ningchuan watched the whole process without blinking!

When Kosaburo picked up the hammer and started the second hammering,

Ningchuan spoke directly in his heart.

"System, start settlement!"

[Congratulations to the host for successfully watching Kosaburo's forging skills for three hours, activating the ten thousand times cultivation return system! ]

[Start practicing settlement now! ]

[Settlement successful, congratulations to the host for successfully obtaining the cultivation return of watching Kosaburo's forging skills for 30,000 hours! 】

【The host's understanding of Kosaburo's sword-forging technique has been greatly improved! 】

Feel the cultivation returned to him by the system.

Ningchuan already has a very clear understanding of Kosaburo's sword-forging technique in his mind!

Including the entire sword-forging process, the amount of force required to hammer each part, and the mastery of the fire are all very clear!

Kosaburo, who has already started the second forging, has begun to speed up at this time.

"Boy, how much do you remember from the one I just demonstrated to you?"

While Kosaburo was forging the sword blank seriously, he did not forget to take the time to ask Ningchuan about the progress.

"Almost all of it has been remembered!"

Hearing Ningchuan's words, Kosaburo, who was swinging the hammer in his hand, suddenly paused.

The whole person instantly lost the rhythm of forging, leaving an imperfect place on the sword blank.

It made Kosaburo feel distressed for a while!

When he slowly recovered his forging rhythm, Kosaburo usedHe spoke in an unbelievable tone.

"What the hell?"

"What did you say?"

"I remembered everything? How is that possible!"

"With so many procedures, how can you remember everything at once without watching thousands of times of forging?"

Looking at the shocked look on Lang's face just now.

Ning Chuan smiled and said.

"I remember it, why would I lie to you? There is no benefit."

After answering Geng Sanlang's question.

Ning Chuan stared at Geng Sanlang for a while, and asked a question he had just asked when watching Geng Sanlang forging.

"Old man, you need to control your strength when forging a sword blank, right?"

Hearing this, Geng Sanlang nodded.

Although he didn't understand what Ning Chuan was going to ask.

But he had a hunch that this kid's question might not be so easy to answer!

"Then why do you have to use a hammer to hit the sword when forging it?"

"I think it would be more accurate to cover your hands with Armament Haki and hit the sword blank with your fists, right?"

"In addition, the temperature of the sword can be accurately controlled, which greatly improves the yield rate!"

After listening to Ningchuan's doubts.

Kosaburo's whole old face suddenly turned black.

When he looked at Ningchuan again, he actually showed a look of looking at a fool, and spoke with a little sympathy.

"I say, are you a fool?"

"Think about it carefully, where did the sword blank pass the fire before it was hammered?"

"It's fucking magma! It's magma!"

"Even if it's not magma, but some ordinary furnaces, it's still thousands of degrees high!"

"Can your Armament Haki withstand such a temperature for several hours? It won't burn you to death!"

Kosaburo scolded Ningchuan for a long time before finally stopping.

Seeing that he had left several irregular marks on the sword blank because of scolding Ning Chuan, he felt distressed!

He couldn't figure out what was wrong with this kid's brain!

Why did he think of such weird things all day long?

"You used your hands instead of a hammer to forge the sword blank. How, how..."

"Fuck, what are you doing?"

"Are you fucking going to die?"

Just when Kosaburo was still spitting out Ning Chuan in his mind.

He turned his head and saw a scene that almost scared him to death!

Ning Chuan, the "greenhorn", actually pushed the workbench away.

He picked up the sword blank on the table and inserted it into the hot magma.

Then, he clenched his hand covered with powerful armed color domineering into a fist.

He started to beat the sword blank in his hand directly in the hot magma that was rolling and bubbling under the workbench!

Seeing this scene, Kozaburo was so scared that he threw his hammer away!

He rushed towards Ningchuan's position regardless of everything.

Ningchuan smiled faintly, looking at his hands that had just touched the hot magma, and whispered.

"System, start settlement!"
