Konoha: Starting with Sage Mode

"Send two teams of secret agents to continue investigating Orochimaru's laboratory that has been left outside. We cannot let any clue slip by."

"Tsunade commanded."

According to Minato's report, Orochimaru established numerous laboratories abroad during World War II, in many countries.

Since Orochimaru had anticipated this traitor's actions, he likely left behind many things in these laboratories that could threaten Konoha.

Furthermore, she personally felt that Orochimaru was very likely not dead; this was her intuition as a woman.

"Ha~"

The ANBU ninja obeyed the order and then used the Body Flicker Technique to leave.

……

Time continued to fly by, and before we knew it, another two months had passed.

The most significant event during this period was undoubtedly the defection of Orochimaru, one of the three legendary ninja of Konoha. This incident shocked all factions in the ninja world, as many were surprised that this hero of Konoha would defect.

Therefore, many people felt very sorry after learning that Orochimaru had died at Kirito's hands.

Meanwhile, information about Orochimaru's numerous laboratories throughout the ninja world was leaked by someone, sparking a wave of searches for Orochimaru's laboratories and exposing many of his hidden labs.

Konoha's response was quite strong, demanding that anyone who found Orochimaru's laboratory hand over anything related to Konoha.

Unfortunately, no matter how tough Konoha was on the issue, without being able to confirm who had found Orochimaru's laboratory, Konoha couldn't force these people to hand over the items willingly, and could only swallow their bitterness.

Because of this, Orochimaru's reputation in Konoha became even worse.

Besides the Orochimaru traitor incident, there is another matter that deserves the attention of all forces in the ninja world: a member of the Demon Organization who possesses the Void Ring raided Takigakure and stole the Takigakure treasure, the Hero's Water.

As a result, many transactions involving Hero's Water began to appear in the underground black market of the ninja world.

As these Heroic Waters circulated in the underground black market, conflicts suddenly intensified throughout the ninja world. There were many cases of ordinary ninjas killing Jonin who were of higher rank, and even cases of ordinary people killing ninjas.

Suddenly, the awe of ordinary people towards ninjas diminished considerably, and uprisings broke out in some impoverished areas of various countries.

In order to quell the uprising, the daimyo of various countries requested that the major ninja villages take action to suppress it, which quickly turned the once peaceful ninja world into a battlefield once again.

……

In the Land of Demons, in a basin within the dense northern forest, the former flying fortress of the Sky Ninja still stands quietly. However, due to a lack of human maintenance, in just a few months, it has become a paradise for plants, covered with a large number of various green plants.

From a distance, it might be difficult to spot the massive flying fortress hidden beneath this patch of greenery.

Suddenly, a violent tremor erupted from the flying fortress, causing a large number of animals living in the flying fortress to flee in terror.

Meanwhile, deep within the flying fortress, in a room that had clearly undergone special modifications, Kirito's Uchiha clone was looking with delight at an eye in a glass container in front of him.

This is an unusual white eye. Unlike ordinary white eyes, its base color consists of numerous pale purple light spots, making it look incredibly mysterious.

This unusual Byakugan is the product of Kirito fusing one of Hyuga Tennin's Byakugans with a large number of Byakugans. It is a Byakugan that has already begun to evolve into the Tenseigan, and the evolutionary stage is quite advanced.

However, Hyuga Tennin's Byakugan at this time was somewhat different from when he had just completed the fusion of a large number of Byakugan.

Previously, it had accumulated a lot of dark emotions due to the fusion of a large number of white eyes, resulting in serious pollution and giving people a feeling of oppression and evil. Now, however, it is as clean as a piece of pure crystal.

"The idea of ​​letting Zero-Tails absorb and fuse with the dark emotions in the Byakugan to complete the purification is correct. In this way, the path of letting it continue to fuse with the Byakugan to evolve into the Tenseigan will no longer be tortuous."

The Uchiha clone said with a smile, then looked down at the strange creature in the glass container that looked like a long black snake.

This strange creature is Zero-Tail.

After more than three months, it finally 'revived' again in the form of a chakra creature.

However, its current size is less than one percent of what it used to be.

The moment the Uchiha clone looked at Zero-Tails, it immediately sensed the Uchiha clone's gaze. It quickly suppressed its greed for the floating eye above its head, curled up into a ball, and hid its head, not daring to meet the Uchiha clone's eyes.

However, when the Uchiha clone turned away and stopped paying attention to it, it couldn't help but stick its head out again and keep looking up at the eye on top of its head.

As a materialized being of dark chakra transformed from dark emotions, it could clearly sense that the dark emotions hidden deep within that eye still intoxicated it. As long as it devoured it, its power would surely be restored quickly.

Unfortunately, the dark emotions deep within that eye, like the incredibly pure dark chakra within it, are primordial. Not to mention consuming them, it is extremely difficult to take them away.

After all, that eye was no ordinary eye; it contained some kind of terrifying power.

If it were at its peak, it would be confident that it could suppress this eye and slowly extract the pure, dark emotions within it. But not now; it needs the help of that hateful human to suppress it.

"Alright, Zero Tail, let's move on to the next experiment."

Just as Zero-Tails was fantasizing about one day turning against the Uchiha clone, the devilish voice rang out again, forcing it to reluctantly return to reality. Then, it trembled as it looked at the human smiling at it.

Zero-tail dared not resist and obediently turned out of the glass container's exit, then entered another glass container, where there was also an eye, which was red.

Zero-tail looked at the red eyes with three tomoe and felt a mixture of longing and fear.

The desire stems from the immense dark emotions contained within this red eye called the Sharingan, while the fear arises from the fact that it must once again act as a conduit, regurgitating the dark emotions it has painstakingly collected and injecting them into this red eye.

Using Zero-Tails to artificially evolve the Sharingan.

This was also an experiment conducted by the Uchiha clones here during this period. First, Zero-Tails absorbed the dark emotions in Hyuga Tenjin's Byakugan, and then Zero-Tails injected these dark emotions into a three-tomoe Sharingan.

The two experiments form a closed loop.

However, perhaps because Zero-Tails' resurrection was too weak, the two experiments took nearly three months to gradually show some progress. The Byakugan experiment was a great success, but the Sharingan experiment encountered a bottleneck.

The idea that the Sharingan absorbs a large amount of dark emotions to complete its evolution is largely correct, because the shape of the three tomoe in the Sharingan in the glass container has obviously changed, and they are very close to being connected to each other.

However, when it came to the final crucial step, it seemed to be blocked by something. Even when he forced Zero to give the Sharingan the pure dark chakra within his body, it was to no avail.

Zero-Tails quickly completed the task of transferring the dark emotions he had just obtained from Hyuga Tenshi's Byakugan, but the Sharingan in the glass container still showed no new changes.

Upon hearing this, the Uchiha clone couldn't help but show a disappointed expression, sighing, "It seems that it's difficult to make the Sharingan evolve simply by fusing the dark emotions born from the Byakugan. That's true, since the dark emotions of the Byakugan and the dark emotions of the Sharingan aren't the same thing, they're not strong enough."

Chapter 325: Mass-producing Mangekyou Sharingan using the Rinnegan

After a long period of meticulous research, Kirito has gained some understanding of the special power of dark emotions. This is a kind of negative chakra, which can be described as a combination of negative spiritual and physical power.

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

The Sharingan grows by absorbing this negative chakra, and then the Sharingan's special Yin Release chakra, its power, is born.

The Sharingan with three tomoe in the glass container was originally just an ordinary Sharingan with average eye power. However, after being transferred from Hyuga Tennin's Byakugan, which was a fusion of many Byakugan, by Zero-Tails, a dark emotion transfer device, its eye power has increased rapidly.

Kirito actually felt that the power of this three-tomoe Sharingan was no less than that of a regular Mangekyou Sharingan, but even so, it still couldn't evolve into a Mangekyou Sharingan.

His only conclusion was that the level of dark emotion absorbed by the Sharingan was not high enough.

Clearly, for the Sharingan to evolve into the Mangekyou Sharingan, simply accumulating quantity is not enough; quality is also essential.

"In that case, the only hope of artificial evolution is to rely on that thing."

The Uchiha clone frowned slightly, thinking of something unpleasant.

Soon, his brows relaxed again, and he looked at the zero tail in the glass container.

Zero immediately sensed the deep malice in the eyes of the Uchiha clone, and immediately put on his ostrich act again, his whole body trembling.

"What a highly intelligent creature you are! Don't be afraid. I'm about to give you a tremendous opportunity. It just depends on whether you have the ability to take advantage of it."

Upon seeing this, the Uchiha clone smiled.

Upon hearing this, Zero Tail's body became even more powerful.

If it could speak, it would say that it didn't want this opportunity at all.

Unfortunately, it had no right to refuse.

The Uchiha clone clapped his hands together and used the Flying Thunder God Technique to disappear from the spot.

A few seconds later, he reappeared, this time with a glass container in his hand covered with numerous sealing techniques and two sealing talismans radiating powerful Sage Chakra fluctuations.

This glass container is clearly a ninja tool with powerful sealing abilities, and inside it is a purple eye soaked in a green solution. The eye has concentric patterns, making it look mysterious, eerie, and dangerous.

These eyes are Madara Uchiha's other Rinnegan.

It is unknown whether Madara Uchiha has regained a Rinnegan or whether there is some connection between the two Rinnegans. As time goes by, this Rinnegan becomes more and more active, and the ocular power contained within it becomes stronger and stronger.

After Kirito discovered this situation, in order to prevent Madara Uchiha from discovering it through some special ability, he had to spend a lot of money to specially create such a powerful sealing tool for it. He even went so far as to make two more Sage Seal Talismans made of rare sealing materials and Sage Chakra to add a new layer of protection for it.

As soon as the Uchiha clone brought back the Rinnegan, Zero-Tails immediately poked its head out from its curled-up body, staring intently at the Rinnegan sealed within the ninja tool.

Its body trembled even more violently, but the reason for its trembling was not fear, but excitement, immense excitement.

It could strongly sense that the newly appeared eye contained a high-quality dark emotion that it had never devoured before. It had a premonition that if it could devour a portion of the dark emotion within it, it could immediately return to its peak, or even become more powerful.

For a moment, a strong feeling of greed arose in its heart, almost taking over its mind and making it forget its fear.

"It seems you really like the dark mood in it, that's great."

The Uchiha clone watched Zero-Tails' actions and said with a playful smile.

These words struck Zerotail like lightning, shattering its greed and reigniting its fear.

It quickly pulled its head back, not daring to look at the Rinnegan again.

However, the Rinnegan was like a sumptuous feast, exuding an irresistible aroma. Zero couldn't help but sneak a peek, and the more he looked, the more greedy he became, gradually losing himself in the desire for greed.

"This Rinnegan is indeed something that was awakened after fusing two pairs of Mangekyou Sharingan, the power of Indra and Ashura, and the dark emotions of Uchiha Madara who was completely desperate and fallen. It probably contains the most extreme dark emotions in this world, and it is extremely tempting to Zero-Tails."

The Uchiha clone saw that Zero-Tails' eyes were gradually being blinded by the Rinnegan again, and sighed inwardly, then became even more eager to see what would happen next.

That's right, he wanted to use Zero-Tails to transfer the terrifying dark emotion from the Rinnegan to the Sharingan, and use the intense dark emotion of Madara Uchiha's utter despair to make it evolve.

This is the plan he envisions as the most likely to achieve the artificial evolution of the Sharingan.

The reason he hesitated to use Zero-Tails before was twofold: firstly, Zero-Tails had just been resurrected and was too weak; secondly, he was worried about what might happen if the Rinnegan was unsealed; and finally, he held onto a sliver of hope that he could use ordinary dark emotions to evolve the Rinnegan.

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

Zero-Tails may seem weak now, but the Uchiha clone knows that this wicked thing has always been very dishonest and has a great talent for acting. It has been secretly devouring the dark emotions in the Byakugan to recover and pretend that it is still weak.

The Uchiha clone estimated that even if this evil thing hadn't recovered to its full strength, it was at least half of its former power.

As for the unexpected problem of the Rinnegan, he has already made preparations. The laboratory he is currently in was carefully modified by him over a long period of time and is covered with a large number of sealing techniques. It is almost a ninja world with powerful sealing abilities in itself.

If anything unexpected happens to the Rinnegan, he immediately activates the sealing power in the laboratory to severely damage it.

"Come on, try to extract the dark emotions from it."

Seeing that Zero-Tails was about to lose control, the Uchiha clone decisively tore off the Sage Art sealing talisman on the sealing ninja tool, then opened the seal, exposing the Rinnegan inside to the outside world.

Zero-Tails suddenly rushed towards the Rinnegan with a whoosh, enveloping it with its body.

The next second, a powerful dark emotion was extracted from the Rinnegan by Zero-Tails using its special ability, and then transformed into materialized dark chakra.
