Naruto: The Age of Ninja Swordsmen Begins from the Hidden Cloud Village.

The rapid progress was made possible thanks to the Byakugan's ability to see through things, allowing it to directly see the fusion status of the material's interior, discover interlayer cracks immediately, and then hammer and fuse them together during hot forging.

This is also the key to a good knife. There must be no defects in the blade, especially cracks and impurities, otherwise it will break in battle, which is fatal to the person using the knife.

In addition to material fusion, the quality and strength of the materials is also an issue, which can be solved by spending money.

In addition, as a disciple of Ichiro Kusama, he could purchase those materials in the Iron Kingdom at cost price, which is why he achieved such a big improvement in one year.

If it were someone else, even a genius in this field would have to study hard for at least ten years.

Tamura Hao, who was well prepared, came to the forging room again, and Uchiha Hikaru and others also came to watch.

"Teacher, please cut along this line."

Taking out the heavy hammer from Douge, Tamura Hao drew a circle on the hammer head and signaled Fukai to start cutting.

Fukai didn't say much, he drew out his ninja sword and used the supersonic thunder sword to cut it.

The Supersonic Thunder Blade itself has a super strong cutting ability, and the Toga is a ninja sword forged from metal that conducts earth attribute chakra. Although it is extremely hard, it is no longer indestructible when facing the restrained Thunder Blade.

Of course, it was not easy to cut. It took me four full minutes to cut that piece.

Tamura Hao put it into a stove that had been lit long ago to heat it up, and also put in a thunder sword.

In comparison, it was more difficult to heat up the large piece of cut, and the thunder sword was burned red first.

Tamura Hao rolled it out with chakra thread, put it on the anvil and hammered it, and finally folded it and forged it into a whole piece.

Although the Thunder Blade is the most advanced ninja sword, it focuses more on assisting the Lightning Release Ninjutsu, and its own sharpness and strength are not very good.

If you really have to face off against a famous sword like Kusanagi Ken, you will definitely be cut in half or even cut off.

These knives themselves are not indestructible, especially the beheading sword, which has broken countless times.

This is a question of emphasis on material selection and forging techniques. In order to enhance the auxiliary effect of the thunder sword on ninjutsu, one can only make a trade-off between the hardness and sharpness of the blade.

Now Tamura Hao needs to correct it and increase the strength of the blade, even if it means giving up the auxiliary strength of ninjutsu.

Take out a top-grade crucible that has been prepared long ago, put the thunder blade material to be forged into an iron ingot into it, and then add the alloy powder that has been prepared long ago.

He had already studied the materials of several ninja swords and tried to mix them, coming up with several sets of suitable ratios of supplementary materials to further enhance the strength and toughness of the ninja swords.

After putting the crucible away, Tamura Hao merged his chakra with that of the Ten-Tails. Two circles of magatama appeared in the depths of his pupils, one inside and one outside, for a total of six magatama.

"Amaterasu!"

He decisively activated the Amaterasu eye technique, and a black flame appeared and fell into the crucible.

This is another achievement of his training over the past year. His chakra fusion with the Ten-Tails has been further enhanced, and he can now release the Amaterasu flame without damaging his own eyes.

Of course, it can only be in the form of a flame. If it gets bigger, it will damage one's own eyes. Shedding blood and tears is the lightest consequence. If it is not careful, the eyes may be blinded.

The power of this offensive pupil technique is too strong, far exceeding the force load that is unleashed when the Eight Thousand Spears Pupil Technique is used.

Seeing the black flames, Uchiha Guang's face turned cold.

That's her pupil technique, you shameless villain!

The Amaterasu flame is indeed powerful. Even a single flame can emit extremely high temperatures. It will melt the thunder sword in a short while and then fuse with the metal powder.

This is not over yet. Tamura Hao extended the Diamond Blockade and sent a fist-sized Rasengan on the top into the crucible. He used the Rasengan to fully stir the alloy inside and extinguish the Amaterasu flame at the same time.

The Rasengan continued to rotate, and at the same time the temperature of the alloy slowly decreased, and finally it became a viscous state before the Rasengan was retracted.

Ichiro Kusama was the first to step forward to take a look. He felt so excited when he saw the transparent and crystal-like viscous alloy liquid.

"It was indeed the right decision to accept you as my disciple."

It took him a while to calm down, and Ichiro Kusayama was very emotional.

The fusion of materials has always been a difficult problem for their swordsmiths. Ordinary steel is easy to melt, but some special metals are difficult to melt, especially those chakra-conducting metals.

They could only fuse the various metals by folding and forging, but the fusion was not perfect.

But they didn't have a better solution. They didn't have a flame that could melt those special metals, and the flame from burning charcoal alone was far from enough.

But now, with this strange flame, the metal that gave him a headache was melted in an instant. Coupled with the special stirring method, it was enough to make the various metals inside blend perfectly.

With this method, as long as the material quality is high enough, forging a top-notch sword will not be a problem, and even mass production is possible.

Of course, this deep fusion is not absolute. The strength and toughness of materials obtained by many fusion methods may not be comparable to those of folding forging of two materials, but this fusion has an advantage that folding forging cannot match.

That is, the conductivity of chakra will be better and smoother, without any faults. This integrated structure is more conducive to the fusion of chakra and sword.

"It is also an honor for me to be my teacher's disciple."

Tiancun Hao has great respect for this knife-making teacher. He has learned a lot and improved a lot in the past year.

Seeing his disciple's sincerity in respect, Ichiro Kusayama was very satisfied. He did not disturb him and stepped aside to continue watching.

While the alloy liquid had not yet cooled down, Tamura Hao placed it on the anvil and forged it quickly. It soon became a scimitar shape. In order to save materials, he even forged an axe blade directly. After that, it only needed a little polishing.

After a careful observation using his Byakugan's ability to see through things and making sure there were no flaws, he covered the back of the knife and half of the blade with a thin sheet of iron made from part of the beheading sword, then used hot forging to make the two fit perfectly, and finally placed them in the furnace to maintain the temperature.

Then, beat the red-hot part of the amulet into a ball and put it into the crucible, then add the prepared alloy powder and heat it with the Amaterasu flame to melt it again.

"Aunt Yuye!"

Tamura Hao told Uzumaki Tamanoha that the next step was to use the Rasengan to wrap up all the metal inside. His own chakra was far from enough, so Uzumaki Tamanoha had to do it.

"Otama Rasengan!"

The vortex jade leaf that had been explained long ago extended a diamond seal, and placed a large jade spiral ball into the crucible, driving the alloy liquid inside to rotate rapidly, allowing it to fully fuse.

Follow the same procedure and stop stirring only after the alloy liquid becomes viscous.

After the alloy solution cooled to a certain degree, he put it on the anvil and forged it quickly, and soon it became a large naginata without a blade. He imitated the shape of the Kusukomo-kiri sword of Whitebeard next door, and he was too lazy to give it a name, so he borrowed the name of Kusukomo-kiri.

Seeing the shape of the big naginata, Ye Yueai rubbed his hands excitedly. This was his exclusive weapon.

Ever since he finished refining his body with the secret medicine, his physical fitness has greatly improved, and the simple ninja sword is no longer enough to exert his own strength.

If he really wanted to use a ninja sword, he would like to have a large naginata, so that it would be more powerful.

He still used his Byakugan's ability to see through things carefully, and only after confirming that there were no flaws on the handle or blade did he proceed to the next step.

The Thunder Blade alloy, which is shaped into a scimitar, is inserted into the slot on the blade of the Oonagata.

There was no blade there yet, so he planned to use the steel clamping method to embed the thunder knife alloy into it as a blade. After all, Ye Yueai's major was thunder attribute.

It's just that there is a restraint conflict between the thunder blade with lightning attribute and the earth-attributed cutting material, so it is wrapped with a layer of thin iron sheet made from the fragments of the beheading sword as a buffer.

Because the chakra-conducting metal of the beheading sword is of water attribute, it can absorb the opponent's blood and at the same time has a good enhancement to water-style ninjutsu.

The chakra attributes of Yeyue Ai are thunder, earth and water, which just match the three.

He hammered the blade one by one and observed it carefully with his X-ray vision. Only after confirming that they fit perfectly together did he embed the extended silk thread into the slender slot reserved on the blade.

In this way, the lightning attribute chakra can be injected directly into the blade through this thin line without conflicting with the blade.

Of course, there is also a layer of metal skin of the beheading sword inside the slender card slot to isolate it, and thereby gain the ability of the beheading sword's metal to absorb the enemy's blood and physical strength.

The beheading sword can not only repair itself, but also absorb the life force from the enemy's blood to restore the user's physical strength, allowing the user to continue fighting while swinging the beheading sword.

This is a very practical ability. The only pity is that the beheading sword is too fragile and may be interrupted during the battle between Jonins.

Finally, the handle, blade and blade are quenched using different liquid media and different temperatures to improve strength.

The blade is already sharp because it has been hammered out, so it only needs simple polishing to become extremely sharp.

"Brother Ai, try this Congyun Qi!"

He picked up the forged Kusunokiri and looked at it carefully. After confirming that there were no flaws, Tiancun Hao waved it and was very satisfied with the center of gravity inside. He immediately threw it to Yeyue Ai who had been waiting for a long time.

Uzumaki Vanilla, who had been waiting on the side, walked forward quickly, took out the ice water that had been kept warm in the box, and picked up a towel to wipe the sweat off Tamura Hao.

This made Uzumaki Kushina very angry. That villain was so despicable.

Ye Yue Ai on the other side caught Cong Yunqie and swung it for a while. He was also very satisfied with the shape and center of gravity of the knife. Then he injected lightning chakra into it along the thin line.

In an instant, a blazing white electric light flashed on the white blade, and then it vibrated at an extremely high speed. It was the Supersonic Thunder Blade.

"Good knife!"

He swung the Cong Yunqie and cut it across the bluestone floor. The blade cut through like cutting tofu, and Ye Yueai became even more excited.

This is the ninja sword he wants, the one that suits him best.

Although the heirloom hand knife of their Yeyue clan is very sharp, it would be better if they could have a good knife.

After all, no matter how strong the palm is, it is still flesh and blood, and cannot compare to this top-notch sword.

Fukai's eyes were burning with excitement when he saw this scene. Although the ninja sword in his hand was good, it was just good and could not compare to the supreme item.

"Old sir!"

After trying a few Lightning Release Ninjutsu with Kusunokiri again, Yeyue Ai handed it to Ichiro Kusanagi.

It was agreed at the beginning that Junior Brother had to forge a sword of supreme level here before he could leave the school.

Ichiro Kusama took the Kusukumaki sword and examined it carefully, then swung it and performed some sword techniques.

Although the sword he often uses is the Odachi, the Odachi and the razor are both long swords, and their sword techniques have many similarities, and they can be swung with great force.

"You can start your apprenticeship now!"

After demonstrating a set of sword skills, Ichiro Kusama nodded with satisfaction, acknowledging the achievement, and was shocked in his heart.

He originally thought that it would take the kid at least ten years to forge a supreme artifact, but who would have thought that he could do it in just one year.

He was far better than he had imagined. Although he could see that the kid was using other abilities to assist in knife-forging, this was a good thing. With the assistance of that ability, he would definitely be able to go further on the road of knife-forging.

Maybe this child can really forge a famous sword like Kusanagi's sword.

Chapter 110 Three Knives and a Flash

"This is the result of my research on the two Kusanagi swords. It's a pity that I haven't fully understood the secrets. You can only figure out the rest on your own."

Taking out a scroll that had been prepared long ago, Ichiro Kusama felt a mixture of regret and anticipation.

I have studied the two Kusanagi swords for a year, but I have only figured out some of the surface mysteries. As for the deeper ones, I still have no idea.

If you haven't reached that level, you will never be able to understand it.

"Thank you, Teacher. I will definitely study it thoroughly and forge a famous sword that will be passed down through the ages."

Tian Cun Hao raised his hands and took the scroll seriously.

He was very clear about his own weight, and he used cheats to forge the sword, especially the perspective ability of his white eyes.

Without this, he could only create swords of the Good Grade at best.

There is no other way. The traditional casting method relies entirely on experience and feel, and the better ones use chakra for sensing.

However, the chakra sensing ability is far inferior to that of the Byakugan at a subtle level, so the improvement speed of traditional swordsmiths is so slow.

The disciples before Master Caoshan all became masters after the age of 30, and their learning time exceeded 20 years.

I was able to learn the sword this year only by cheating. In the future, I will need to hone my skills in real sword-making, which means making more swords.

Of course, he had other ideas about the casting of the famous sword handed down from generation to generation, which was Yin and Yang Escape, especially Yin Escape.

"When are you leaving?"

Ichiro Kusama asked, knowing that the boy wouldn't stay long.

"In three days, I still need to forge two ninja swords."

Tamura Hao also needs to forge two ninja swords, one for Fukai and one for the Third Raikage.

Next, the Third Raikage will have to snatch the Nine-Tails' parts, and the stronger he is, the better.

"You will follow me to the General's Mansion in three days!"

Ichiro Kusayama did not forget his original promise. As long as the child could forge the supreme great achievement, he would take him to meet Admiral Mifune to see the realm of man and sword becoming one.

"Thank you, teacher!"

Tamura Hao was overjoyed. He was indeed looking forward to the realm of unity between man and sword. Moreover, Admiral Mifune himself had many unique methods, so he could just learn from him.

After talking with his teacher Ichiro Kusama, Tamura Hao went back to rest and had a sumptuous meal.

"How long until Konoha's Chunin Exams begin?"

After eating and drinking, Tamura Hao asked while enjoying Uzumaki Vanilla's massage service under Uzumaki Kushina's gritted teeth gaze.
