Shinji had previously tested Yin Du's ability, and when Yin Du broke away from Yakumo's body in the form of a spirit body, he could move within a range of about twenty-five kilometers from Yakumo.

If it was farther away, Yin Du would not be able to maintain the spirit body.

And when Yakumo transplanted the red dragon eye and successfully survived the first generation of cell transplant surgery, Yin Du's strength was also greatly improved along with Yakumo.

One of the most obvious improvements is that Yin Du's spirit body has been further enhanced.

Now, as long as she has Yakumo's permission, she can move within a range of about fifty kilometers from Yakumo.

Fifty kilometers!

Such a distance is basically beyond the detection range of all perceptual ninjutsu and children's jutsu, and even the bug-like 'Kagura Heart Eye' of Xiang Phosphorus is powerless at this distance.

Therefore, today's Yakumo is equivalent to having the ability to launch a surprise attack on the enemy within 50 kilometers with the 'Spiritualization Technique', and his body will not lose the ability to protect himself because of the distance of the spirit body like Kato Due.

At this point, the duo of Yakumo and Yin Du is already terrifying.

But that's not their limit.

The red dragon's terrifying ability to manipulate blood had caused Shinji to accidentally develop a secret technique called the 'Blood Clone Technique'.

This secret technique can only be performed with a red dragon eye, and Shinji who has lost the red dragon eye can no longer perform it, so he passed on the knack of the 'blood clone technique' to Yakumo.

I didn't think that it was this that made Yakumo accidentally discover another use of the 'Blood Clone Technique'.

When Yakumo casts the 'Blood Clone Technique', Yin Du can control this blood clone in the form of a spirit body and comprehensively enhance the ability of this blood clone.

You must know that the blood clone with the entity is stronger than the shadow clone that purely relies on chakra simulation, and when Yin Du's spirit body enters the blood clone, the strength is even more explosive, almost no different from Yakumo's deity.

Shinji, who discovered this, immediately realized the value of this, so today's test was born.

"It's about forty-five kilometers from Konoha here, and it's within the limits of your activities!" After a pause, Shinji said, "What we are going to test today is whether your range of motion can be further expanded after you have a blood clone as a temporary body. ”

Yin Du looked confident: "My lord, after performing the 'Blood Clone Technique', the weakness of my previous spirit body has completely disappeared. In this state, I feel that even if I go to another country in one go, there will be no problems. ”

Shinji pointed in a direction: "You won't know the results until you test it, let's go!" ”

Not daring to disobey the leader, Yin Du immediately 'snorted', like an arrow off the string, and galloped away in the direction of Shinji's finger.

"Huh..."

Shinji let out a soft 'huh' and frowned slightly.

Because of Yin Du's speed, it is obviously beyond Yakumo.

However, theoretically, the limit of the blood clone is only infinitely close to the power of the deity, and it is absolutely impossible to surpass the power of the deity.

Soon, Shinji reacted.

It's not that the strength of the blood clone surpasses the deity, but in the use of power, Yin Du is obviously a level stronger than Yakumo, so there is a strange thing that the strength of this doppelganger is even higher than the deity.

After a moment's pause, Shinji followed.

Yin Du and Shinji's speed is at the upper ninja level, plus this time it is a test, so he does not hesitate to rush at full speed of Chakra, and because the speed is too fast, the scenery on both sides of them is distorted and deformed as if the picture has been pulled.

In a few moments, they exceeded the limit of fifty kilometers.

And the limit that was originally insurmountable for Yin Du now seems to be in vain, she has no intention of stopping, and continues to rush forward.

Sixty kilometers ...

Seventy kilometers ...

Eighty kilometers ...

Seeing that it was already eighty kilometers away from Konoha Village, Yin Du in front didn't have anything unusual, let alone stopped, and Shinji, who was following behind, couldn't help but be amazed.

Ninety kilometers ...

A hundred kilometers ...

Shinji's eyes froze slightly.

This is already the limit of his 'Nakhiki' range, and if he continues to stay away from the village, he will not be able to use the 'Naobi' link to Yakumo who stays in the village.

So he paid attention to the link of 'Zhibi' and tested another guess in his heart.

Soon, Yin Du, who was galloping, was a hundred kilometers away from Konoha.

One hundred kilometers is the limit of the 'Zhipi', and once the range is exceeded, the 'Zhipi' will not be able to sense and link to the marked target.

After confirming that Yakumo was out of the range of 'Naobi', Shinji suddenly activated 'Naobi' and tried to link Yakumo.

In the blink of an eye.

The induction of 'Naobi' did not spread in the direction where Konoha Village was located, but pounced on Yin Du in front of Shinji, and then something strange happened, Shinji was actually more than a hundred kilometers away from Yakumo, and connected Yakumo with 'Naobi'.

"Is that so..."

Something that shouldn't have happened happened, but Shinji wasn't too surprised.

The reason why he made this attempt was because he found that as Yakumo adapted to the red dragon eye, the subtle feeling between Yakumo and Yin Du was further enhanced.

In other words, as long as one of Yakumo or Yin Du is within his 'Nakami' range, then he can use the induction between Yakumo and Yodo' to link both of them at the same time.

After confirming this, Shinji secretly thought: "Although Yakumo and Yin Du already have this kind of induction, it is by no means as strong as it is now!" What reinforces this feeling between them? Red dragon's eye? Is it still a primary cell? ”

Compared to before, Shinji prefers red dragonan.

Because in the primordial air, the first generation of cells did not seem to show any strange abilities in terms of soul and sensing.

And as a concretized children's art of Yin Escape Chakra, the soul and induction aspects are obviously the domain of the red dragon's eye.

"Could it be the special ability of the red dragon's eye?!"

A conjecture was born in Shinji's mind.

At this time, Yin Du in front of him was like a wild horse on the loose, still galloping.

He silently calculated the distance, and found that Yin Du was almost one hundred and thirty kilometers away from Konoha Village at this time, so he shouted: "Stop!" ”

Yin Du stopped when he heard this.

Shinji looked Yin Du up and down, and while assessing her condition, he asked, "How are you feeling now?" ”

"It feels great!" Smiling, Yin Du said: "The feeling of being pulled by Yakumo at the moment before has completely disappeared, and I feel that I can now be free and free from the constraints of distance." ”

Shinji said secretly: "It's because of the protection of the entity, so Yin Du's spirit body is no longer bound by distance, and can be free to stay away from Yakumo..."
