Naruto: Get Stronger by Hanging Up.

The generals and four emperors that Shimotsuki Kozaburo mentioned as being able to destroy a country were referring to island countries, and definitely not land countries.

In the world of pirates, most countries are island countries.

But Ye Yu didn't care about these things. He knew very well that he was strong enough to protect himself now.

There is no need to worry about the issue of strength anymore.

He has no intention of going out to sea now. He knows very well what his purpose in coming to this world is.

If it was purely for strength, he would not choose to take such a big risk to travel to other worlds.

The day to go to Shimotsuki Village to study has arrived again. As usual, Ye Yu went straight to the sword shop after arriving in Shimotsuki Village.

At this time, Shimotsuki Kozaburo was looking at a red-hot long sword in the stove.

He came back to his senses only after Ye Yu came in.

When Shimotsuki Kozaburo saw Ye Yu coming, he laughed and said, "Come here quickly, you have forged a terrifying sword."

Ye Yu was stunned for a moment, then came to the forging furnace and looked at the long sword that was burning red in the furnace.

The temperature of the furnace was extremely high, but the knife showed no signs of melting at all.

And the red-hot surface is still shining.

When Ye Yu approached, the knife even trembled.

Looking at the knife in the furnace, Ye Yu smiled and said, "Is it forged? After all, it has been forged for more than ten days, so it should be ready."

Shimotsuki Kozaburo sighed, "This sword was forged with your domineering aura and blood. It has been forged with intelligence."

"This is definitely a demon sword."

Ye Yu nodded, he felt it too.

The demon sword Shimotsuki Kozaburo is no stranger.

Because he also forged great swords such as Wado Ichimonji and Enma. Among them, the Enma sword is also a demon sword that can automatically absorb the user's domineering aura.

But from the perspective of Shimotsuki Kozaburo, the sword in front of him is likely to be of the supreme level of a sharp sword as soon as it appears, without the need for domineering qi cultivation.

Most of the supreme swords are black swords, because those who can master the supreme swords are all the top strong people in the world.

Shimotsuki Kozaburo looked at the sword flashing with red and black lightning in the furnace and swallowed his saliva. "It has only just been forged, but it has already taken on the characteristics of a black sword. I can't imagine what kind of powerful person can control this sword."

Shimotsuki Kozaburo looked at Ye Yu and said, "People choose swords, but swords also choose people. This sword is absolutely an extremely terrifying demon sword. If it is not controlled properly, the person holding the sword may die. Don't you think carefully about whether you want to master this sword?"

Shimotsuki Kozaburo was giving a sincere reminder.

This sword is much more bizarre than the two large swords forged by Shimotsuki Kozaburo. It is already wrapped in Conqueror's Haki and Armament Haki before it even comes into being. Moreover, it vibrates automatically without any ability input. This sword is too bizarre and powerful.

Just from the sharp aura emanating from this knife, he could feel the huge difference between it and other great knives, even the supreme great knives.

Ye Yu stood in front of the furnace, looking at the knife in the furnace, and said calmly, "This is the first knife I forged, and maybe the last one. I will not give up."

Shimotsuki Kozaburo looked at Ye Yu for a while before sighing, "That's right, only someone with your courage can possibly wield this demon sword."

"Don't you want to give this knife a name?"

Ye Yu looked at the knife wrapped in black and red lightning in the furnace and smiled, "Let's call it crossing the line."

This name made Shimotsuki Kozaburo stunned for a moment.

He had no idea why Ye Yu would choose such a name.

"Why did you choose this name?"

Ye Yu said casually, "It's nothing, I just picked it up casually."

Shimotsuki Kozaburo was speechless.

"This is a famous sword that could potentially reach the level of a supreme sword. How can you be so careless?"

Ye Yu explained, "No matter how good the name is, it's just a sword. If its owner is not good enough, even a supreme sword will become an ordinary sword."

The swords in this world can indeed be nurtured by the domineering Qi. Even a sword that is only at the level of a quick sword can be nurtured by the domineering Qi to become a great quick sword, and may even be upgraded to an unparalleled great quick sword.

The strength and reputation of a knife ultimately depends on the person who uses it.

Chapter 398 Splitting the Sea with a Sword

However, Ye Yu did not name this knife casually. Crossing the boundary actually means crossing the world.

This means that Ye Yu's expectation for this sword is that it can last until he crosses this world, and he can even take it away from this world.

Ye Yu already values ​​this knife very much.

Unlike other swords, Ye Yu's sword is not in the shape of a traditional samurai sword, nor is it a naginata like Whitebeard's. Instead, it is straight throughout, similar to the long straight swords of Sasuke and Fujitora.

The whole body is straight and has no patterns.

Very simple and rustic.

But this knife exudes a strong domineering aura at all times.

Moreover, it contains both Conqueror's Haki and Armament Haki.

It was only then that Shimotsuki Kozaburo realized that Yohane actually possessed the domineering aura.

This made him even more certain that Ye Yu's future would definitely be extraordinary.

Although Conqueror's Haki is not rare in the New World, it is still exclusive to the strong, and there are still a large number of strong people who do not have Conqueror's Haki.

Not to mention that Ye Yu can integrate his Conqueror's Haki into the sword, so you can imagine how terrifying the strength of his Conqueror's Haki is.

When it was ready to be taken out, Shimotsuki Kozaburo looked at Ye Yu and said, "You will take out this knife."

In the past few months, Ye Yu has completely mastered the sword-forging technique, and his level is much higher than Shimotsuki Kozaburo.

The Yuejie knife was made by Ye Yu himself.

Ye Yu nodded, stood in front of the stove, and instead of picking up any utensils, he reached out to grab the knife.

Shimotsuki Kozaburo was stunned. After he came to his senses, he quickly stopped Ye Yu.

"There are tools here. Your hands will be ruined if you do this."

But Ye Yu didn't listen and calmly stretched out his hand. The moment Ye Yu's hand entered the furnace, his entire arm was completely wrapped in armed color domineering.

The black armed color domineering was wrapped around Ye Yu's hand, and the color was completely invisible to the naked eye.

The most basic is the attachment of armed color, which can be seen in black.

When the Armament Haki is entangled, the Armament Haki flows in the hands and can be directly blasted out from one point.

Ye Yu's armed color domineering naturally cannot be seen.

However, Shimotsuki Kozaburo, who was standing next to him, could feel the armament domineering power of Yohane.

The intensity of his Armament Haki is so high that just the aura that escapes can be felt by the human body.

Ye Yu's hand, which was imbued with Armament Haki, grasped the blade that had not yet been hilted.

The moment he just touched the boundary, the blade that was originally only shining with black and red lightning suddenly appeared with black and red lightning as thick as an arm.

"Click"

"Rumble"

The lightning spread instantly at an extremely fast speed. Seeing that these black lightnings were about to blow the swords and knives into ruins, Ye Yu's eyes condensed slightly.

At this moment, the lightning that was spreading around disappeared instantly.

Even the lightning that was originally wrapped around the cross-border blade disappeared.

This horrifying scene shocked Shimotsuki Kozaburo again.

"Is this the taming of the domineering lightning? And the domineering lightning that this sword just unleashed is definitely more terrifying than the Supreme Great Blade."

"This sword is at least at the level of a supreme sword, Ye Yu. You made a sword of the supreme level on your first try."

Shimotsuki Kozaburo was extremely shocked and looked at Ye Yu with disbelief.

He couldn't imagine how powerful this ten-year-old child was at this moment.

All this happened within a few months. In just a few months, Ye Yu had become so powerful that he could not even estimate it.

After Ye Yu took Yuejie out of the furnace, he finished it according to the steps of forging a sword.

Finally, the knife was equipped with a very ordinary and simple wooden handle.

The scabbard is also a very ordinary wooden scabbard.

No special materials were used, and of course, Ye Yu didn't have the money to buy them.

However, Shimotsuki Kozaburo originally planned to use special materials to make a handle and scabbard for Ye Yu.

But Ye Yu rejected it.

He prefers a simple and rustic style.

A sword like Fujitora's is the one that best suits Ye Yu's aesthetic taste.

After dealing with the crossing of the border, Ye Yu brought it to the back mountain.

Shimotsuki Kozaburo followed Yohane to the back mountain and stood on the coast of the back mountain.

Looking at the vast ocean, Ye Yu smiled and said, "How about I give you a try?"

Shimotsuki Kozaburo also laughed and said, "I haven't seen how good your swordsmanship is."

In fact, Shimotsuki Kozaburo was also looking forward to it. Although he knew that Ye Yu was very strong, he still didn't know how good his swordsmanship was.

At the same time, he also wanted to know the power of this supreme sword forged by Ye Yu.

Ye Yu stood on the shore and slowly reached out to grasp the hilt of the knife.

Even though Shimotsuki Kozaburo, who was standing next to him, had seen many storms before, he was still very nervous at this moment.

"Qiang~"

There was a sound of drawing a sword, and Ye Yu swung the sword towards the sea.

The next moment, a fault suddenly appeared on the vast ocean. It was like a picture was broken, and the ocean was split into two halves.

The sea that was hundreds or even thousands of meters deep could not block Ye Yu's sword energy.

The sword energy spanned hundreds of kilometers, and the sea was split open with a crack hundreds of kilometers long. The land under the sea was also split open, with a length of hundreds of kilometers and a depth of several kilometers.

It was just a moment, but Shimotsuki Kozaburou saw it clearly.

It made his scalp tingle and the corners of his mouth twitched slightly.

"Is this, this, this really something a human can do?"

He was sure that Ye Yu's knife strike just now was absolutely a casual one.

But the knife he swung casually actually split the sea, and even the seabed was split open.

At this time, Ye Yu was definitely not a swordsman, but was already at the level of a great swordsman. Even with just this one sword strike, he felt that Ye Yu was much stronger than Oden back then.

But Ye Yu is only ten years old.

This is the scariest place.

At the age of ten, Ye Yu already possessed strength that surpassed Oden's back then, and he was also a great swordsman, but ten years old is not the peak period for a strong man.

How powerful will Ye Yu be in the future?

Simply unimaginable.

After Ye Yu split the sea with a sword, he felt that he no longer needed to worry about his strength.

Even if he is not the most powerful person in the world at this moment, he is definitely one of the people standing at the top.

Such strength is enough for him to go to sea safely.

Of course, he naturally wouldn't go out to sea now. He was still too young and there was no point in going out to sea.

Slowly putting away the knife, Ye Yu nodded with satisfaction, "It's quite useful."

Hearing Ye Yu's words, Shimotsuki Kozaburo smiled bitterly and said, "Of course it's useful. Just now I was just guessing that this sword might be at the level of a supreme sword. Now I can confirm that this sword has surpassed the supreme sword and is definitely a sword worthy of being called a divine weapon."

Ye Yu didn't care. Whether it was a divine weapon or not was just the difference between the strength of the opponent.

Ye Yu’s invincibility in the Naruto world made him very clear that there was no such thing as a god. He was just a person who was much stronger than others.
