The Hidden Mist Blacksmith, forging the glory of the Ninja Sword Style!

In addition, Uehara Shu's swimming and diving abilities were already quite good, and his water jutsu was perfect. For Uehara Shu, there was practically no difference between being in the water and on land.

Just like the underwater creatures that live in the water.

In fact, Uehara Shu could unleash even greater power in the water.

"This greatly enhances my ability to protect myself."

"I will not leave Kirigakure for a very long time to come, and at least I will not leave the Land of Water."

"If anyone threatens me, I will immediately go into the water."

"Very few people can keep up with me."

"Even the ninjas from Kirigakure won't do."

Uehara Shu himself was a Water Release ninja, so he knew a lot about Water Release ninjas.

Even the ten loquats and the green ones cannot achieve true underwater breathing.

It's just that compared to other ninjas, they can stay for much longer.

According to Osamu Uehara, the only creature capable of underwater breathing is Kisame Hoshigaki, who has fused with Samehada.

Another possibility is that members of the Hozuki clan might be involved.

However, Yuan Xiu could not be certain about this.

Uehara Osamu picked up the nautilus.

At this point, the patterns on the box were already filled with light.

"The shape of this pattern, at first glance, looks just like a circuit board."

"However, their functions are indeed somewhat similar."

The box is small; Uehara Osamu can hold it completely in one hand.

"The use of the nautilus requires implantation into the body. If it is truly highly compatible with Hozuki Suigetsu, implanting it into such a small child's body is also a problem."

A flood of information rushed into Uehara Osamu's mind.

Nautilus.

Type: Box weapon.

Quality: Perfect.

Ability: The power of Shura Opening Box and Fish-Dragon Fusion is used to transform into a mermaid, greatly increasing basic attributes such as strength and speed. Perfect quality, with effects close to the real thing.

Note: According to the third rule of the blacksmith, the power of this ninja tool cannot harm the blacksmith.

Uehara Shu's attention was drawn to the phrase "the effect is close to the real thing".

"In that case, the power of this ninja tool should be quite good."

Uehara Shu walked out with the nautilus.

"Is the repair finished?"

"Yes."

"What kind of ninja sword is it? May I take a look?"

Qing showed a somewhat expectant expression.

Uehara Shu shook his head.

"This time, it's not a ninja sword."

Uehara Shu took out the nautilus and handed it to Ao.

"The materials we obtained this time are not enough to forge a ninja sword, but only to forge this kind of ninja tool. However, its ability is still acceptable. Senior Ao, you can give it a try."

Uehara Osamu knew that Nautilus was most likely not a good match for Blue.

However, the two are now considered to be quite close.

During Uehara Shu's forging process, Ao stood guard outside, fulfilling his duties diligently, even waiting until midnight without uttering a single complaint.

After Juzo Biwa left, Ao took his place.

In this situation, if Uehara Shuu doesn't even let Ao try, it would be disheartening.

As a ninja, in addition to having sufficient strength, connections and influence are also very important aspects.

Especially when an individual's strength is insufficient.

If it reaches the level of Six Paths Naruto, that's a different story.

One person can sweep through the entire ninja world.

Personal connections and influence are not that important.

Qing is now considered a member of Uehara Shu's network, so Uehara Shu naturally wouldn't push her away.

"Okay, I'll give it a try."

Uehara Osamu handed the nautilus to Ao.

Just as Uehara Osamu had predicted, the compatibility between Nautilus and Blue was not even up to standard.

Just like before, when the Third Mizukage obtained Kiriichimonji.

No notification sound rang in Uehara Osamu's mind.

Ao tried to channel his chakra into the vessel.

However, it was like throwing a stone into the sea; there was no response.

The Nautilus is different from the ninja swords that Uehara Osamu forged before.

"It doesn't seem like that will work."

Ao showed a somewhat disappointed expression and handed the nautilus back to Uehara Osamu.

"I didn't feel anything similar to what Yuri and Juzo felt."

Uehara Osamu took the nautilus.

"That's because there's no proper connection. Forcing it will only consume extra chakra, not only failing to increase strength but also potentially affecting one's own power."

Qing nodded.

"Indeed."

Uehara Osamu said, "It's a bit of a shame. If you could be compatible with Ao-senpai, we wouldn't have to make another trip to the Mizukage Building. Now we can only go to the Mizukage's place."

"Senior Qing, shall we go over there now?"

Qing had no objections.

"Row."

The two boarded a small boat and left Forging Island, heading towards the direction of Water Shadow Island.

Qing quickly adjusted her mood.

Ao was somewhat disappointed that he couldn't get the ninja tools to work properly.

Ao witnessed the changes that Biwa Juzo underwent after obtaining the Blue Rose Sword and was very envious.

However, Qing was only slightly disappointed.

Qing knew very well that this was no one's fault.

It's just that they didn't fit together.

Qing had no complaints about Yuan Xiu.

In fact, Ao was already very grateful to Uehara for giving the nautilus to Ao to try first.

"We want to see Lord Mizukage."

"Minister Uehara, please wait a moment while I go and inform him."

The attitude of the ninja guards at the gate towards Uehara Shu was completely different from before.

Even though Uehara Shu didn't show up much in the entire village.

However, the head of the forging department is a true high-ranking official in the village.

If there's any village meeting, Uehara Osamu can always make suggestions, and they'll vote on them.

"it is good."

Soon, the guarding ninja returned.

"Minister Uehara, the Mizukage is in his office. You may go directly up there."

"Thank you."

"Minister Uehara, you're too kind."

Qing followed closely behind Uehara Shu.

One eye, covered by an eye patch, even the surgical scar is completely concealed.

"Mizukage-sama."

The Third Mizukage closed the document in his hand, looked at Uehara Shu, and smiled.

"Xiu, is something the matter?"

Uehara Osamu took out the nautilus.

"Lord Mizukage, I have crafted a new ninja tool called Nautilus. I would like to find a suitable user for it in the village. The higher one's Water Release talent, the greater the chance of a good fit."

Uehara Shu couldn't directly say "Hozuki clan," so he could only mention "water release talent."

"A new ninja tool?"

The Third Mizukage showed a surprised expression.

"Kiriichimonji, Blue Rose Sword, Smiling Aoe, Dragon Bone, and now this one."

"Xiu, you are now completely worthy of the title of Grand Master Blacksmith."

Uehara Osamu modestly replied.
