The cultivation base is returned ten thousand times, and the starting strength is at the Four Empero

Watching the moment when Ning Chuan stepped into the sword-making room holding an ordinary iron-grade sword blank.

Kozaburo's mouth curled up and he smiled in his heart.

"You are a little self-aware and didn't waste the good sword embryos I worked so hard to save."

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

Feel the fiery scent of iron and fire in the air.

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

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

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

"Kousaburo is indeed a master swordsmith. He can use the power of nature so skillfully to forge swords!"

"Boom!"

Just when Ningchuan was admiring in his heart that Geng Saburo had found such a good place to practice sword.

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 large amount of sparks flew out.

"Forging is the soul of sword-making!"

"For a good knife, every inch of it must go through a thousand trials and tribulations, from the tip to the blade and then to the blade body, from thick to thin, from soft to hard!"

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

Ningchuan stared at Kozaburo's extremely focused face.

I nodded silently in my mind and took his words to heart.

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

"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!"

Having said that, Kozaburo changed the subject and continued with a smile on his face.

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

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

"I'm going to start forging next, so don't blink at me, kid!"

"Otherwise, if you miss this time, I won't show you how to forge in slow motion next time!"

Say it.

Kozaburo simply picked up an iron hammer and covered it with armed color domineering.

Insert the sword blank deep into the magma, wait until it burns red, then raise the hammer and start forging!

"This place needs a good beating!"

"Hit lightly here!"

"Speed ​​and power must be even in this place!"

……

Although Kozaburo wanted to demonstrate it to Ningchuan at a slow speed.

But in fact, his speed was not slow, and the hammer in his hand was almost sending out sparks.

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

He still watched the entire process of forging Kozaburo carefully from all angles!

Three hours later, Kozaburo finally stopped his first forging.

Ning Chuan watched the whole process without even blinking!

When Kozaburo picked up the hammer and started hammering for the second time.

Ning Chuan spoke directly in his heart.

"System, start settlement!"

[Congratulations to the host for successfully watching Kozaburo's sword-forging skills for three hours and activating the ten thousand times return system for cultivation! ]

[Start practicing now! ]

[Solution successful, congratulations to the host for successfully obtaining the reward for watching Kozaburo's sword-forging skills for 30,000 hours! ]

[The host's understanding of Kozaburo's sword-forging skills has greatly improved! ]

Feel the cultivation points returned to you by the system.

Ningchuan already had a very clear understanding of Kozaburo's sword-forging skills in his mind!

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

Kozaburo, who had already started forging for the second time, had begun to speed up.

"Boy, how much of what I just demonstrated to you did you remember?"

While Kozaburo was forging the sword blank seriously, he also took the time to ask Ningchuan about the progress.

“I’ve almost memorized it all!”

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

The whole person lost the rhythm of forging in an instant, leaving an imperfection on the sword blank.

This made Kozaburo feel distressed for a while!

After he slowly recovered his forging rhythm, Kozaburo spoke in an incredulous tone.

"What the hell?"

"What did you say?"

"Remembered everything? How is that possible!"

"With so many steps, how can you remember them all at once without watching and practicing them thousands of times?"

Looking at Lang's shocked expression just now.

Ning Chuan spoke with a smile.

"Remember it, remember it. Why would I lie to you? There's no benefit in it."

Finished answering Kozaburo's question.

Ning Chuan stared at Kou Saburo for a while and asked a question that he had just raised when he was watching Kou Saburo forging.

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

Hearing this, Kozaburo nodded.

Although I don’t understand what Ningchuan wants to ask.

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

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

"I think it would be more accurate to cover my hands with Armament Haki and punch the sword embryo with my fists, right?"

"In addition, the temperature of the sword can be precisely controlled, greatly improving the yield rate!"

After listening to Ningchuan’s doubts.

Kozaburo's whole old face suddenly turned dark.

When he looked at Ning Chuan again this time, he actually showed a look as if he was looking at a fool, and spoke with a little sympathy.

"I say, are you missing a bone in your head?"

"Think carefully, where did the sword blank get heated before it was hammered?"

"That's fucking lava! It's fucking lava!"

"Even if it's not magma, but some ordinary furnace, it would still be thousands of degrees hot!"

"Can your Armament Haki withstand such a high temperature for several hours? I can't burn you to death, you little bastard!"

Kozaburo scolded Ningchuan for a long time before finally stopping.

He felt distressed when he saw that there were several irregular marks on the sword blank because of scolding Ning Chuan!

He is now a little confused. What's going on with this kid's brain?

Why do you think about such weird things all day long?

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

"What the hell, what are you doing?"

"Are you freaking dying?"

Just as Kozaburo was still angrily scolding Ningchuan in his mind.

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

Ning Chuan, this "young and foolish" guy, actually pushed open the workbench.

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

Then, he clenched his hand, which was covered with powerful Armament Haki, into a fist.

He started hammering the sword blank in his hand right into the bubbling, scalding magma beneath the workbench!

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

He rushed towards Ning Chuan's location regardless of everything.

Ning Chuan smiled faintly, looked at his hands that had just touched the hot magma, and muttered softly.

"System, start settlement!"
