Konoha: Sage Body

Katsuyu-sama.

This is the sage with terrifying survival skills that Kirito is thinking about right now.

This sage is the owner of Shikkotsu Forest, one of the three major sacred places in the Shinobi world. In fact, Shikkotsu Forest is also home to only one Katsuyu-sama, and there are no other slugs.

This sage is incredibly huge, much larger than a tailed beast.

The Slug Sage's most skilled ability is healing, making it the perfect summoning beast for medical ninjas. When Pain of the Six Paths caused havoc in Konoha, many ninjas in Konoha were able to avoid death thanks to the Slug Sage's clones keeping them alive with healing.

The Slug Sage also has the ability to split and communicate with its clones.

Kirito believes that the Slug Sage's ability to split is one of the immortal arts she possesses.

This splitting ability is very powerful. Once mastered, it can truly make you immune to any physical damage, ignore the damage of swords and various toxins, and you will no longer have any physical weaknesses.

As you can see from the performance of the Slug Sage in the original plot, if the Slug Sage's clone is cut, it will not bleed, but the cut body will directly turn into two new clones in place, which can be re-merged afterwards.

Kirito is very envious of this ability of the Slug Spirit. When he has the time in the future, he will definitely obtain the Summoning Scroll from Tsunade to make a contract with the Slug Sage, and then personally go to pay a visit to this sage who is good at healing.

In this way, the new combat system constructed in Kirito's mind has begun to take shape.

For attacks, there is the Storm Release ninjutsu technique, which will be the focus of research and development in the future.

For defense, there is the Shukaku Shield.

For control, there is the Quicksand Whirlpool, which was developed easily using Shukaku's sand manipulation ability, and the improved version of Sealing Technique: Adamantine Sealing Chain.

For perception, there are the four currently mastered perception abilities, and for movement, there is the Lightning Transformation Technique.

For healing, there is Tsunade's future development of the One Hundred Healing Marks and the Slug Sage's Split Sage Technique.

"Next, I will focus on improving these techniques. It's good to have goals, and I don't need to improve my strength randomly like a headless fly."

Kirito opened his eyes slightly, let out a long breath, and smiled.

The abilities he had mastered were really a bit too complicated, and they were just a bit too comprehensive. This was all his own fault for being too good and too greedy.

However, if it came to combat, there were currently many jutsu that he couldn't use.

For example, his most skilled jutsu, Sealing Technique, he had already understood during his battle with Ebizo that it would be difficult for him to use it on this veteran Kage-Level powerhouse.

The reason is that this old guy is so cunning. When fighting him, he is always on the move, never giving him the chance to secretly set up a seal to ambush him. Even if his Sealing Technique is set up quickly, if his opponent keeps choosing to fight while walking, there is nothing he can do about it.

Apart from the Adamantine Sealing Chain and the Dead Demon Consuming Seal, other Sealing Techniques that require time to set up the sealing array to be effective are difficult to use in battles above Kage level.

Dead Demon Consuming Seal is the ultimate one-for-one sealing technique, and should only be used as a last resort.

Therefore, Adamantine Sealing Chain becomes the only sealing technique he can use against Kage-Level powerhouses.

This sealing technique, which was originally exclusive to members of the Uzumaki clan with a special constitution, is indeed powerful. Used in conjunction with Puppet Technique, it can easily achieve the effect of harming people, and can also be extremely effective against big guys like the tailed beasts.

It is no surprise that this sealing technique can also be of great use against Uchiha Madara's full-body Susanoo.

This sealing technique has an amazing ability to imprison chakra. A special product like Susanoo, which is formed by the power of the Sharingan pupils and chakra, will naturally be restrained by this sealing technique.

I just don't know how much it can restrain it.

Although Madara has lost his Rinnegan, he still has the chakra of Indra and Asura in him. Coupled with the long-term supply of the Tree of God's chakra by the Ten-Tailed avatar, the Sharingan installed on his body later will definitely not be weak.

Kirito got the feeling that the new Sharingan placed on Madara might also be a Mangekyo Sharingan.

After all, Madara had the chakra of Indra and Asura within him, and mastered the power of the myriad things. This was the core strength that allowed the Eternal Mangekyo Sharingan to evolve into the Rinnegan.

It was just a matter of time before it evolved into a Mangekyo Sharingan.

"No, this may be the correct way for the Sharingan to evolve. By killing important people and watching important people being killed, the mind is severely stimulated, the dark side of the heart is expanded, and in the end, the brain produces a special kind of extremely negative Chakra that stimulates the evolution of the Sharingan. It looks like an evil way."

Kirito thought about the way the Sharingan evolved and the way Uchiha Madara's Rinnegan was born, and thought thoughtfully.

He felt that he should conduct an experiment on the evolution of the Sharingan.

He wanted to see if the Sharingan would complete its evolution under the stimulation of other powers, for example, if it was nourished by the power of Wood Release and Sage Chakra.

Judging from the current changes in the Byakugan and Ketsuryūgan Bloodline Limits, these two powers could cause the two Bloodline Limits to evolve.

Although this evolutionary process was relatively slow, it had been progressing all along, and in particular, when using Sage Chakra to activate abilities, the form had obviously changed.

He can now extract Wood Release and Sage Chakra from his body, and no longer needs to have the Sharingan implanted in him. He can completely remove it and experiment with it outside, for example, implanting it in a new White Zetsu.

"If Chizuru's strength exploded to its full potential, she would have the strength of an elite Jōnin. This kind of strength is not bad for someone her age, but it's still lacking. We must find a way to quickly increase her strength, otherwise how will she become my good helper in fighting Uchiha Madara together in the future?"

Thinking about the evolution of Sharingan, Kirito couldn't help but think of Chizuru, and then thinking about helping her improve her strength.

His recent strength has improved rapidly, which has seriously irritated his little friend, but he knows exactly where his strength comes from. It is absolutely impossible for Chizuru to reach his level in a short period of time, unless Kirito helps her cheat.

In fact, the cheat he gave Chizuru is already not small.

The curse mark is precisely the cheat code he has given Chizuru. Because of the curse mark, Chizuru has begun to come into contact with natural energy and Sage Chakra. Although the curse mark Sage Chakra is a very inferior type of Sage Chakra with poor quality, it is after all Sage Chakra, which also nourishes the Sharingan.

Because of this, Chizuru, who is only 11 years old, has a Sharingan with a power of sight that already surpasses the Sharingan of other veteran Uchiha elite jōnin by a wide margin.

Kirito had carefully observed that every time Chizuru opened her curse mark, the three magatama in her Sharingan would change in some way. This was clearly the beginning of the evolution of her Sharingan into the Mangekyo Sharingan.

It was precisely because he saw in Chizuru the appearance of a kind of Sharingan evolution that was not a 'normal' Sharingan evolution within the Uchiha clan that he believed the Sharingan could be evolved using other methods.

This method of evolution is obviously slower, but the advantage is that it will not cause people from the Uchiha clan to turn black and become arrogant and paranoid.

To be honest, the Mangekyo Sharingan is indeed a very dangerous thing.

Even if this thing does not evolve into the Eternal Mangekyo Sharingan, it is a consumable, but the power it produces is impossible for even a super kage-level ninja to ignore.

Because the Mangekyo Sharingan is a pupil that reflects the mind, the resulting pupil techniques have infinite possibilities. Once a very powerful pupil technique is born, it will be very difficult for a Six Paths-level strong to deal with it. The most obvious example is the Uchiha clan.

With the spatial and temporal ninjutsu technique Kamui, Uchiha Obito is virtually unstoppable, and this is just the case when he has one Mangekyo Sharingan. Once he has a pair, even if he faces a Six Paths-level strong opponent, he is not afraid.

In short, the upper limit of the power of the Mangekyo Sharingan is extremely high.

However, the Uchiha clan, which possesses such a powerful ability, ended up with a fate of near-extinction in the original plot.

The reason for this is that the Mangekyo Sharingan brings too many side effects to the user. This eye, which is born from killing or witnessing the deaths of loved ones, carries a deep darkness from the very beginning. It corrupts the user, turning them into a self-righteous paranoid who harms others as well as themselves.

Uchiha Shishui and Uchiha Itachi are the most typical representatives of this.

Both were so arrogant and paranoid that they thought they could change the Uchiha clan by their own power. As a result, one was killed by Danzo after having his eye taken, while the other was used by Sandaime and Danzo, eventually becoming a rogue ninja despised by everyone and almost causing the Uchiha clan to be wiped out.

If the two of them had not been so arrogant, had been more reasonable, possessed a little political wisdom, and had learned to balance power, with the strength of the Uchiha clan's three pairs of Mangekyo Sharingan at the time, no matter how weak they became, they would not have ended up completely annihilated.

Uchiha Shishui and Uchiha Itachi had both been precocious, but their insights were somewhat shallow.

If the two of them had not been influenced by the Mangekyo Sharingan, become arrogant and paranoid, always thinking of achieving their goals on their own, and always belittling and ignoring the power of others, if the two of them had grown up a bit more, gained some more insight, and with their abilities, it would have been possible for them to change the Uchiha clan.

"If a completely new and safe path can be found for the Uchiha clan's Sharingan to evolve into the Mangekyo Sharingan, the danger of the Uchiha clan will definitely be greatly reduced, which will be beneficial for the future integration of the Uchiha clan into Konoha and for them to make more contributions to Konoha."

Kirito thought to himself.

He is now a Kage-Level powerhouse, even if he is still young, but it is time to start considering fighting for enough power in Konoha and establishing his own influence, and then complete control over Konoha.

A good man needs three allies.

Learning from the examples of Uchiha Shuichi and Uchiha Itachi, he would not be arrogant enough to control Konoha by himself.

He had to win over enough allies before he could truly control Konoha and ultimately achieve the goal of unifying Konoha.

And in this process, the Uchiha clan was of the utmost importance.

Once he gained the support of the Senju clan and the Uchiha clan, Konoha would basically be under his control.

He now has the support of Uchiha Homura and Uchiha Chizuru, both of whom are very important figures in the Uchiha clan, but they do not represent the entire Uchiha clan.

If he wants to gain the support of the Uchiha clan, he must be strong enough on his own. Only by defeating these people who insist on strength above all else will they take his words seriously.

He already has this.

But simply convincing the Uchiha clan through force will only get them to listen, at best. He also needs to offer them sufficient benefits and favours to truly win their hearts and minds.

A brand new and safe way to evolve the Sharingan is undoubtedly a very good gift.

With this gift, he, who has mastered the core technology, is not afraid that these Uchiha ninjas, who have an almost insane obsession with power, will fall for it and obediently jump into his pot, and then become his own personal hit men.

The new method of evolving the Sharingan can also greatly reduce the chances of the Uchiha clan producing a blackened madman like Uchiha Itachi, which can be said to kill several birds with one stone.

"The power of Wood Release and Senjutsu. Chizuru's Sharingan is now supported by the power of Senjutsu. With her current physical fitness and strength, she should be able to withstand the backlash of Wood Release."

Kirito thought with a slightly furrowed brow.

The power of Wood Release is very strong, but it is also very dangerous, because Hashirama cells possess extremely strong aggressiveness.

The reason why the Hashirama cells in the White Zetsu's body behave so mildly is because the God Tree cells in the White Zetsu's body are essentially an even more terrifying existence than the Hashirama cells, which makes the Hashirama cells harmless.

But once the Hashirama cells enter the body of an ordinary person, they will definitely tear off their sheepskin disguise and return to being vicious evil wolves.

"In order to transplant Hashirama cells into other people, it is necessary to develop a drug that can stabilize the Hashirama cells."

Kirito ultimately could not bear to let Chizuru become a guinea pig, and decided to conduct some research on Hashirama cells and consider giving Chizuru the power of Wood Release after achieving certain results.

However, he soon wanted a new way for Chizuru to obtain the power of Wood Release.

That was to use his Sage Chakra and blood to form a curse mark.

Like Wood Release, the curse mark is also highly aggressive, and its aggression is strong enough to modify the limits of the blood lineage to a certain extent.

The reason why the Ketsuryūgan on his body did not reject him was that he used his Sage Chakra to infect it and complete control it from the source.

The Curse Mark Chakra in Chizuru's body essentially belongs to Sage Chakra and is a higher existence than Wood Release Chakra.

Therefore, theoretically, Chizuru already has the ability to control the Bloodline Limit of Wood Release.

"Let's find some other lab rats to experiment on first and see what the success rate is. If I go to Chizuru now, the girl will definitely be unable to resist the urge to use Wood Release and ask me to perform a Hashirama cell transplant on her right away."

Kirito shook his head.

Then, his gaze fell on his hands.

Next, a certain Otsutsuki from Boruto: Naruto Next Generations appeared in his mind.
