After a long and meticulous study, Kirito has already had a certain amount of research on the special power of dark emotions, which is a negative chakra, which can be said to be a combination of negative spiritual power and physical power.

However, this negative chakra is also graded, and the more extreme the negative emotion, the higher the dark chakra level.

It is by absorbing this negative chakra that the writing wheel eye grows, and then gives birth to the special yin chakra of the writing wheel eye pupil power.

Now the three-hooked jade writing wheel eye in the glass container was originally just a very ordinary writing wheel eye, and the pupil power was also very average, but with the help of the dark emotion transferor of Zerotail, the dark emotion transfer from the Hinata tennin's white eye that fused with many white eyes, the pupil power was rapidly improved.

Kirito actually felt that the pupil power of this three-hooked jade writing wheel eye was actually no worse than that of an ordinary kaleidoscope writing wheel eye, but that's it, it still couldn't evolve into a kaleidoscope writing wheel eye.

In this regard, the only conclusion he came to was that the level of dark emotions absorbed by the writing wheel was not high enough.

Obviously, if you want to evolve into a kaleidoscope writing wheel, you can't just rely on quantity accumulation, you must also have quality.

"In this way, only that thing can hope to complete artificial evolution."

The Uchiha clone frowned slightly, thinking of something not so good.

After a few moments, his brow furrowed again, and he looked at Zerotail in the glass container.

Zero Tail immediately felt the deep malice in the eyes of the Uchiha clone, and immediately pretended to be an ostrich again, and his whole body trembled.

"It's really a highly spiritual creature, don't be afraid, I'm just going to give you a great chance, it depends on whether you have the ability to use it."

Seeing this, the Uchiha clone smiled.

When Zero Tail heard this, his body became stronger.

If it could speak, it would now be tempted to say that it didn't want the opportunity at all.

Unfortunately, it does not have the right to refuse.

The Uchiha clone clapped his hands and used the Flying Thunder God Array to disappear in place.

A few seconds later, he reappeared, and in his hand there was an additional glass container with a large number of seals engraved on it, and two seals that exuded powerful immortal chakra fluctuations were attached to it.

This glass container looks like a ninja with powerful sealing powers, and inside it is a purple eye soaked in a green solution, and the eye has a circle of lines, which looks mysterious, weird, and dangerous.

This eye is the other reincarnation eye of Madara Uchiha.

I don't know if Madara Uchiha has regained the relationship between one of the reincarnation eyes and that there is some kind of connection between the two reincarnation eyes, as time goes by, this reincarnation eye becomes more and more active, and the pupil power contained in it is also getting stronger and stronger.

After Kirito found out about this situation, in order to prevent Madara Uchiha from discovering it with some special ability, he had to spend a lot of money to create such a ninja with a strong sealing ability for it, and even did not hesitate to make two immortal seal talismans made of cherished sealing materials and immortal chakra materials, adding a new insurance to it.

As soon as the Uchiha clone brought back the eye of reincarnation, Zero Tail immediately burrowed his head out of his curled body and stared intently at the eye of reincarnation in the sealed ninja.

Its body trembled even more, but the reason why its body trembled at this time was not fear, but excitement, incomparably excited.

It can strongly feel that there is a high-quality dark emotion in the newly appeared eye in front of it that has not been devoured so far, and it has a hunch that if it can swallow part of the dark emotion inside, then it will immediately return to the peak, or even more powerful.

For a moment, it couldn't help but feel a strong feeling of greed in its heart, which almost took over its heart, making it forget its fears.

"Looks like you like the darkness in it, that's great."

The Uchiha clone looked at Zero's move and said with a playful smile.

As soon as these words came out, it fell like lightning in Zero's heart, splitting the greed in its heart into pieces, and fear regained its identity.

It quickly retracted its head, not daring to look at the eye of reincarnation again.

It's just that the eye of reincarnation is like a feast with supreme deliciousness, exuding a very tempting aroma of food, and Zero Tail can't help but look at it secretly, and then the more he looks, the more greed in his heart becomes, and he is gradually lost in greedy desires.

"This reincarnation eye is worthy of being opened after fusing the dark emotions of two pairs of kaleidoscope writing wheel eyes, the power of Indra and Asura, and the completely desperate and depraved Uchiha Madara, I am afraid that it contains the most extreme dark emotions in this world, and the temptation for Zero Tail is very great."

The Uchiha clone saw that Zero Tail was gradually blinded by the eye of reincarnation, sighed in his heart, and then looked forward to what happened next.

That's right, he wants to use Zero Tail to transfer the terrifying dark emotion in the eye of reincarnation to the eye of the writing wheel, and use the intense dark emotion of Madara Uchiha in it to complete its evolution.

This is the plan he envisioned as the most likely to complete the artificial evolution of the Sharingan.

He didn't try to use Zerotail for a long time, on the one hand, Zerotail had just been resurrected and his strength was too weak, and on the other hand, he was worried that something would happen once the reincarnation eye was unsealed, and in the end, he had a glimmer of hope that he could use ordinary dark emotions to make the reincarnation eye evolve.

Now that hope has been shattered and the time is ripe, it's time to complete this plan.

Zero's current situation seems to be very weak, but the Uchiha clone knows that this bad-eyed thing has always been very dishonest and has a great talent for acting, and it has always been secretly devouring the dark emotions in the white eyes to recover and disguise itself as weak.

The Uchiha clone estimates that even if the strength of this bad thing has not yet recovered to its heyday, it is at least about half.

As for the problem of accidents in the eye of reincarnation, he is also ready, he is now in this laboratory that he has spent a long time carefully transforming, and he has carved a large number of sealing techniques, which is almost a ninja world with powerful sealing abilities in itself.

As soon as something unexpected happened to the reincarnation eye, he immediately activated the sealing power in the laboratory to deal a serious blow to the reincarnation eye.

"Come on, try to get the dark emotions out of it."

The Uchiha clone saw that Zero Tail couldn't help it, so he decisively tore open the immortal seal on the seal ninja, and then opened the seal, exposing the reincarnation eye inside to the outside world.

Zero Tail suddenly rushed towards the reincarnation eye with a roar, and wrapped the reincarnation eye with his body.

In the next second, a powerful dark emotion was pulled out of Samsara by Zero Tail with a special ability, and then turned it into a materialized dark chakra.

But to the surprise of both the Uchiha clone and Zeroo, it was only a small part of the dark emotion, and the dark chakra it formed was so large that it expanded like a balloon.

Seeing this, Zero Tail couldn't help but excitedly absorb it into his body, and then let out a hysterical scream.

The dark chakra that it had just absorbed into its body actually began to absorb its dark chakra in turn, and it wanted to resist, but found that it was useless.

"Sure enough, there was an accident."

Seeing this, the Uchiha clone said with a calm face, and then clapped his hands together, using the Vajra blockade, using the immortal chakra to create two chakra chains, and quickly restrained Zerotail's body.

I saw that the reincarnation eye that was entangled by Zero Tail at this time emitted a bewitching purple light, and suddenly moved around like a living thing.

If it weren't for the Uchiha clone, even if he used the Vajra blockade to bind Zerotail, it would have broken free from Zerotail's shackles.

"Why don't you hurry up and get the dark emotions out of here, you idiot."

After the Uchiha clone completed the restraint with the Vajra blockade, he immediately scolded Zeroo.

Thanks to the help of the Uchiha clone, Zerotail finally has some ability to fight against the Eye of Samsara, and although it still craves the dark chakra of the dark emotions that devour the Eye of Samsara in its heart, its fear of it is greater than its greed.

Because it just felt obvious that if it didn't have the help of that damn human, it would be devoured by this one eye, and there would be no scum left.

This eye has the power to kill it entirely.

From now on, it turned out to be the prey.

Zerotail didn't dare to slack off, and separated a black tentacle to wrap around the Sharingan, using it as a channel to reconvert the terrifying dark chakra that he had just absorbed into a dark emotion, and then with difficulty to convey it to the Sharing's Eye.

The reason why it was difficult was because it found that the terrible eye that was wrapped around it was violently resisting, trying to retract that dark emotion.

What kind of sacredness is that eye, it can be fought against by instinct, and it is still with the help of that powerful human being.

Fortunately, it has no consciousness of its own, and it does not know how to use its own power flexibly, and instinct alone is not enough to resist the combined attack of it and that hateful human.

On the other side, the three-hooked jade writing wheel eye in the glass container was rapidly changing its appearance after absorbing the dark emotions from the samsaric eyes.

In fact, it is one step away from evolving into a kaleidoscope writing wheel, and the accumulation is already enough, what is missing is only a key to change quantity to quality, and the dark emotion with the extreme despair of Madara Uchiha in the eyes of reincarnation is undoubtedly this key.

In just a few seconds, this writing wheel eye, which was originally just a three-hook jade, successfully completed a qualitative change and evolved into a real kaleidoscope writing wheel eye.

At this time, the three-hook jade pattern in it has become an inverted triangle, and the whole eye is lit up with a bewitching red light, which looks like the eye of reincarnation, with spirituality, and is no longer a simple organ.

"Hahaha~, it's successful, my idea is really correct, with the reincarnation eye of Madara Uchiha, I have the possibility of mass-manufacturing kaleidoscope writing wheel eyes, and I can even use this to create my own reincarnation eye."

Kirito looked at the newly born kaleidoscope writing wheel eye in the glass container, and suddenly showed a surprised expression on his face, and laughed.

At the same time, in the new headquarters of the old roots, Madara Uchiha, who was closing his eyes and recuperating in the country of Taki, suddenly opened his eyes, and the reincarnation eye on his right eye was experiencing a sharp pain at this time, and a line of bloody tears flowed out of his eye socket.

"Ah~, what's going on, why does the reincarnation eye suddenly hurt."

Madara Uchiha covered his eyes with his hand and said with a painful expression.

"Madara-sama, are you alright, what's wrong with the eye of reincarnation?"

Madara Uchiha's sleeve asked anxiously.

Madara Uchiha can die, but the eye of reincarnation can't have problems.

Madara Uchiha knew what was going on, and he found that there was nothing wrong with this reincarnation eye on his body, but it just hurt inexplicably.

"Tosaka Kirito, it must be him, he must be doing something to my other reincarnation eye, which is why this reincarnation eye on my body senses."

Soon, Madara Uchiha thought of the reason for the abnormality in his reincarnation eye, and said through gritted teeth.

Suddenly, a strong anger arose in his heart, and he wanted to kill Konoha immediately and smash Tosaka Kirito, a bastard who dared to do bad things to his reincarnation eye, into pieces.

"It's him, what did this bastard do to make Madara-sama's reincarnation eye sense, did he destroy another reincarnation eye?"

Hei Jue continued to ask anxiously.

Although only one eye of reincarnation can also activate the Eye of the Moon project, after all, two eyes are safer.

"No, my other reincarnation eye is still there, go, let Orochimaru come over, I have sensed the whereabouts of the other reincarnation eye, it is in the northwest direction."

Madara Uchiha endured the pain and said angrily.

Black Jell did it right away.

After a while, Orochimaru appeared in front of Madara Uchiha, and at this time, Orochimaru had changed back to his original form.

He looked at Madara Uchiha's Sharingan that was bleeding and tearful, and suddenly had a strong curiosity, but he could also find that Madara Uchiha was in a bad mood now, and he didn't dare to stimulate this madman.

So, he said expressionlessly: "Chief, what do you command?" ”

"Orochimaru, you go to the northwest immediately now and go with him."

Madara Uchiha ordered directly.

Orochimaru was slightly dissatisfied with the tone of Madara Uchiha's commanding subordinates, but when he thought that this guy in front of him was still holding his own life, he still obediently obeyed the order, bowed his head and replied, "Yes." ”

As soon as the words fell, an old man who also had reincarnation eyes and kaleidoscope writing wheel eyes suddenly came out of the ground and looked at Orochimaru with eyes that had no emotional fluctuations.

Orochimaru looked at the old ninja in front of him, and his heart was shocked, he was well-informed and very familiar with the high-level of the major ninja villages.

The old ninja in front of him was clearly the third generation of Mizukage of the Mist Ninja Village, although his appearance had changed a little, but the other party was right, and he was sure that he didn't recognize the wrong person.

What kind of ability did this Uchiha Madara use to bring this powerful ninja who had died back to life, and also obtained the power of the eye of reincarnation and the eye of the kaleidoscope writing wheel.
