He didn't know what they were busy with, nor what they were going to do next. Anyway, after exchanging greetings, they parted ways for the time being.
What made Daimaru feel fortunate these past few days was that the unstable Gaara hadn't come to trouble him, nor had he heard of anyone being killed by the increasingly crazy Jinchuriki of the One-Tail.
The Magnet Release characteristic of the One-Tailed Shukaku was truly too special. With chakra that carried its own sealing properties, ordinary sealing techniques were useless against this sand incarnation in the shape of a tanuki. Only by sacrificing Gaara's way of life and using the Spirit Medium styling method could the One-Tailed Shukaku be temporarily quieted.
However, this was not a long-term solution. Once the volatile One-Tailed Shukaku woke up, it would be a catastrophe for everything around it.
Only I am left alone again!
Daimaru, who was quite used to being alone, wasn't sentimental enough to get emotional over such a small thing. It was just that being in Konoha without even a person to talk to, the sense of crisis inevitably brought a little anxiety.
At this time, only ninjutsu training could make Daimaru temporarily forget some of his worries.
Unfortunately, among the five ninjutsu in the scroll given by Captain Otokaze, only one did not require hand seals: the very special "Third Eye".
At first, Daimaru didn't pay much attention to this reconnaissance-type ninjutsu. It wasn't until he truly settled down to study it that he realized something was wrong.
The so-called "Third Eye" isn't in the category of Earth Release branching—Sand Manipulation Technique—but is a rather difficult secret ninjutsu.
Sand is just a medium for casting the jutsu. Changing to other forms of chakra nature transformation wouldn't make much difference. Earth, Water—as long as the chakra manipulation level keeps up, it's not a problem. If a ninja is truly gifted, Lightning, Wind, and Fire work too, though their stealth capabilities have their own pros and cons.
As long as the eyeball formed by chakra is connected to one's own optic nerve, the jutsu is preliminarily complete.
The difficulty isn't there; it lies in transmitting the visual signals seen by the "Third Eye" to the main body. This tests the level of the ninja casting the jutsu.
If the distance isn't too far, one can directly use chakra sensing to share vision, but that's useless; seeing directly with one's eyes is the same. The only benefit is seeing some blind spots.
However, using a secret jutsu that consumes chakra just to achieve such a goal is obviously not worth the loss. Not to mention the waste of energy, concealment is also hard to guarantee.
Of course, this jutsu still had great benefits for Daimaru. When using the Polarizing Light Killing Formation, which rendered his main body completely invisible and caused a loss of vision, the "Third Eye" was an excellent supplement for perception.
Otokaze's intention was good. This jutsu was useless for the vast majority of Sand Ninjas, but it was very suitable for Daimaru, who possessed special Wind Release tactics.
But this was too far from the long-distance reconnaissance Daimaru had envisioned.
How to transmit the information seen by the "Third Eye" from a distance to the main body—that is the core of this jutsu.
Currently, the only ones in the ninja world who could use this secret jutsu were the Fourth Kazekage Rasa and Gaara. The way the two handled it was likely different as well.
Gaara had the innate ability to manipulate sand, so he could just use the "Sand Eye" directly; Rasa used the ability of his Kekkai Genkai to turn an eyeball into Gold Dust, equivalent to directly manipulating a part of his main body, so naturally, there was no problem.
Whether it was Gaara or Rasa, when this father and son used the "Third Eye", the Magnet Release developed from the source of the One-Tailed Shukaku played a role, practically or virtually.
It wasn't to say that one couldn't use the "Third Eye" secret jutsu without Magnet Release, only that the effect would be greatly discounted.
Sure enough, there aren't that many cheap advantages in the ninja world. Having a Shadow Clone Jutsu should be enough to be content!
To bring out the full ability of Secret Jutsu: Third Eye, one either had to be as skilled in Sand Manipulation Technique as instinct, like Gaara, or use a Chakra Nature Transformation to an outstanding degree—not necessarily to the level of Chakra Mode, but at least enough to turn a part of the body intangible.
But the current Daimaru could do neither.
Not to mention the family's Hydrification Technique like Hozuki Suigetsu's, but Lava Release Chakra Mode and Lightning Release Chakra Mode had been successfully cultivated by some.
As for the Wind Release that Daimaru excelled in, a Chakra Mode had never been heard of.
Talent and background couldn't compare, but...
Since the "Third Eye" can't do long-distance reconnaissance, can I think of a way to make the Third Eye see further?
The somewhat disappointed Daimaru had a sudden inspiration.
Although the structure of the human eye is precise, it isn't powerful. There are many creatures whose vision far exceeds that of humans. Thinking of it this way, there was still a lot of room for development.
With this thought in mind, Daimaru abruptly got up and manipulated his Substitute Puppet to push his wheelchair to the rooftop garden of the Konoha Hospital.
At this moment, it was approaching dusk. In the midsummer afternoon, the intense heat had dissipated slightly, and there were more pedestrians on the street again.
"What a nice view! Such earthly fireworks are basically hard to see in the lethargic Sunagakure, right!"
Daimaru muttered to himself. With his back to the setting sun, he closed his eyes, bathed in the slowly blowing warm breeze, and leisurely shut his eyes.
"Let's begin!"
A gust of breeze rolled up sand dust, forming a spirited eyeball near Daimaru's hand.
The first step was simple.
Immediately after, the Sand Eye stopped in front of Daimaru's left eye. In a moment, the nerve connection was successfully completed.
This step might be a bit difficult for most ninjas, but for a puppeteer proficient in human anatomy, it couldn't be simpler.
Subsequently, the Sand Eye turned into a diffuse cloud of sand dust, slowly flying high into the sky. At a place nearly a hundred meters away from Daimaru, it reformed into the Sand Eye.
"The limit of chakra sensing is just this."
This was with the Sand Eye being too light and consuming little, and Daimaru extending it to the limit in one direction. If it were spread all around without blind spots, the distance would be much closer.
Through the Sand Eye, Daimaru clearly felt as if he were at a height of a hundred meters, looking down condescendingly at the busy Konoha.
After manipulating the Sand Eye to move around and roughly figuring out the controllable range, Daimaru opened his right eye.
What a strange experience!
Human left and right eyes were originally meant to be used in coordination. As a result, now, the observation ranges of the two eyes had a severe deviation, weakening Daimaru's ability to judge position and distance through his eyes a little.
