Chapter 1

"Ugh, my head hurts."

Kayn opened his eyes and felt as if someone had hit him on the back of his head with a hammer.

Then, as the pain slowly subsided.

Land of fire, Konoha, Hokage, Uchiha...

A multitude of memories suddenly came flooding back, emerging like how flashbacks are depicted in some movies.

It took Kayn a couple of seconds to recover from that happening, and a couple more to digest and realize what the memories he just got meant.

"I can't believe it... I'm in the world of Naruto. Hah! I got Isekai'd!"

For a writer like himself, and a no-life to top that all up, to be able to travel through an Anime World, actually, not just any other world but to the one that you actually know and love, is such a joyous occasion.

These two happy things combined should be more than enough to put him in a happy state for the next couple of weeks, but...

"Gosh..."

Upon fully absorbing and organizing the memory he just got, he started to realize the actual state of his current situation.

And looking at how fast his expression turned grim, it doesn't seem that good.

"The Uchiha clan going to be wiped out soon?!"

Uchiha Shisui had already committed suicide by jumping off a cliff.

His death means that the Uchiha clan has officially started the countdown to extinction!

Soon, Itachi will join forces with Obito to kill not only his family but the entire clan as well.

Sasuke is the only one who will be left after the massacre... meaning unless the body that Kayn managed to possess is him, then there's no way he'll survive.

Well, it doesn't take much effort on Kayn's part to know that his real name here in this world is also... conveniently similar to his original.

Kayn Uchiha.

(AN: We'll be using that starting from now.)

"... sh*t."

There is not much time left for him.

"What do I do now? Can I just run away?"

Kayn is not from this world. So even though he managed to get the memories of his current body, he is still him.

He still perceives everything through the eyes of the original him. Unbothered by the influence of the emotion of the original owner of his current body.

Besides, he is an orphan both in his previous life and in this life.

Therefore, he had no psychological burden or attachment to the clan or to the people "he" supposedly knows in it.

So running away, he would've done it without a single thought... Well, If he could do it that is.

The idea of running away lingered in Kayne's mind only for a few seconds before he outright rejected it.

The entire Uchiha clan was under surveillance by the Anbu and the Root and could not leave the main gate of Konoha.

Escaping from other places is even more unrealistic.

Konoha is shrouded in a huge spherical barrier, and the moment someone enters or exits, it will be immediately detected by the team assigned to it.

Moreover, even if he really managed to escape from Konoha, there would be no place for him in this vast world.

The way the Sharingan evolved meant that the higher-ups of the Konoha would not allow any Uchiha to survive.

In particular, after the original body learned of Shisui's suicide, he managed to awaken a three-tomoe Sharingan.

Although it is still a three-tomoe, and not as valuable as the Mangekyo, as long as the Sharingan is awakened, it is possible to evolve it into a Mangekyo!

Konoha's top leaders would not take this risk.

As for fleeing alone to the other four major ninja villages and begging for asylum?

Haha, Kayn believed that if he went there alone, the best outcome would probably be to become a breeding tool.

Although that sounds kinda fun at first, being choked in the waist for the entirety of your life... Having your Sharingan dug out of your eye socket would be much better honestly.

All in all, his current situation is a damn bloody hellish start!

But, when all hope seems lost, like how God responds to those who are in need of help, suddenly, a transparent panel pops up in front of him.

Name: Kayn Uchiha

Bloodline Limit: Sharingan (1/6000)

Ninjutsu: Great Fireball Technique LV3 (213/1000), Phoenix Fire Technique LV2 (170/300), Dragon Fire Technique LV2 (113/300), Shadow Clone Technique LV2 (213/300)

Physical Skills: Uchiha Style LV2 (251/300)

Illusion: Hell-viewing Technique LV2 (160/300)

Others: Seal Technique LV2 (170/300), Throwing Technique LV2 (241/300), Voice Acting LV1 (91/100), Acting LV1 (92/100), Writing LV1 (59/100)<

Seeing the window that appeared in front of him and reading all its contents, Kayn had the sudden urge to sincerely thank the original body for having a good relationship with Uchiha Shisui and for being diligent and hardworking during his training, allowing him to not start with a blank slate.

"Wait, isn't this the cheat that I made for my protagonist!?" Kayn's eyes widened.

Before getting Isekai'd, Kayn was actually preparing to start a new book, and the obligatory "cheat" he compiled for the protagonist of that book was the same as the window he's looking at right now.

To make the explanation much shorter, it is basically a system that allows its user to gain experience points to upgrade their skill level. And the limit of it... is nonexistent.

Allowing him to upgrade all his skills infinitely had he got enough experience to do so.

As a wise man once said, watching others suffer is a pleasant experience, but when you are the one suffering from it, it is not such a good feeling.

"If I had known I would be Isekai'd with this, I could've given this system more features..."

Kayn jokingly said to himself making his once tense mood, relax for a bit.

There are no miracles in Naruto. Here, bloodline is above all else!

For example, Guy practiced hard for decades and is still somewhat inferior compared to the titled strongest in the world. Only when he used his final move had he finally got the chance to compete.

And that almost cost him his life.

So most ordinary people can only be passers-by and go with the flow as the major events play out.

Life or death, everything depends on others.

It was a powerless feeling.

The cheat that he got gave Kayn some hope.

Even a powerful power such as Sharingan has a limit! But with his System, as long as he works hard, everything is possible!

"But... there is no time for me to grow up slowly."

The Uchiha clan now has one of its feet in the coffin already and may be gone tomorrow.

Improving ordinary skills won't solve the problem at all.

Unless... he obtained a Mangekyo.

Kayn glanced at the experience bar of his Sharingan and quickly gave up this plan.

[Sharingan (three tomoe): 1/6000]

Because his System was designed by himself, no one understands it better than him.

If you want to get 5999 experience points in just a few days... you might as well go to bed early.

Kayn took a deep breath, put aside his negative emotions, and calmly thought about the possible countermeasures for his current situation.

"Escape means death, and not escaping means death too? Dammit! Fine!, if that's the case then we might as well rise up and resist, kill those damn b*tches!"

Only by dealing with the one who wishes for their demise can the entire clan of Uchiha gain a glimmer of hope! But doing that will be hard unless someone breaks the Uchiha clan's foolish delusions about the Konoha's high-level officials and makes all of them realize that this is a life-and-death struggle with no room for maneuver 

The first thing to do is to change people's mindsets. Not only that but also to learn how to take an actual action.

Planning to stage a coup and do nothing but meetings are such brainded move.

They were determined to launch a violent coup, but in the end they were still fussy about it. At that point, might as well not start anything in the first place.

In Kayn's opinion, with a good clan leader, the Uchiha clan would not be destroyed.

Uchiha Fugaku is undoubtedly a good clan leader, he got that position for a reason. But at this point in time, of all the time he could have released the hidden monkey in his brain, now is when he chose to do so!?

"However, he has been the Leader of the clan for many years and has won the trust of the Clan members. Before the fatal scandal broke out, his position was as solid as a rock."

The first wall has arrived.

If Kayn wants to change the Uchiha ideology, he has to get around this pair of stupid father and son first.

He was not afraid of Itachi. What he was afraid of was that Fugaku, the number one culprit, would repeatedly block him, causing him to miss the last chance to survive.

"We need to find a breakthrough point... so where is the breakthrough point?"

Kayn took out a pen and paper and wrote down a list of names:

Sarutobi Hiruzen, Shimura Danzo, Uchiha Shisui, Uchiha Itachi, Uchiha Fugaku...

After thinking about it, a new name was then added. Uchiha Setsuna.

After scribbling a few words, Kayne put down his pen and smiled at the contents.

"I got it. This will be my key to surviving this place."

For a Clan like the Uchiha that worships the strong, Kayn's three tomoe are of extraordinary significance.

As long as you awaken the three tomoe, you can directly enter the clan's decision-making level and have an actual say.

Before every major action, regular meetings are held to solicit the opinions and views of the entire clan. And with his eyes, he would be able to join that very meeting.

—Shiing!

Kayn opened his eyes, and a pair of three tomoe slowly spun in his scarlet pupils.

All of a sudden, the world is clearer than ever before.

The dust in the air rises and falls.

A fly 10 meters away, under the observation of the Sharingan, moved slower and slower, and finally seemed to be trapped in amber, frozen in place.

The patterns on its wings are clearly visible.

Kayn took out a shuriken and threw it lightly.

The shuriken swept through the air, leaving a long trail.

—Chi!

The body was seamlessly separated.

The confused fly, having Go/jo'd, was left with no choice but to silently crash on the floor.

"This is extraordinary..." This feeling made Kayn obsessed.

He took a deep breath, calmed down, and did not close his Sharingan, carefully sensing and calculating the chakra consumption.

"The consumption of chakra after opening it for half an hour is about the same as using the Great Fireball Technique. Of course, if it is a fierce battle, the consumption of chakra will be faster."

Because the abilities of the Sharingan, whether it is insight, copying, or illusion, all require chakra consumption.

Well, members of the Uchiha clan tend to have more chakra than the others, an advantage that runs in the blood.

Glancing at the experience bar.

+0.5 exp

+0.5 exp

+0.5 exp

+0.5 exp

+0.5 exp

...

After seeing the steady flow of the incoming exps, Kayn nodded in satisfaction.

After that, he then wasted no time and decided to finally start the first phase of his plan.

He walked towards his drawer and took out a well-preserved notebook from it.

As he goes to a nearby table and comfortably sits on it, he starts sorting out his original body's memories of Uchiha Shisui.

A moment after doing that, he then started writing something in the notebook.

After wasting dozens of sheets of paper, Kayn finally wrote a satisfactory work. At least that's what he believed so.

For him, It's just like an actor writing a biography for the character he's playing.

His admiration for his work didn't last that long though, because right after that, he quickly took out another stack of paper from the same cabinet where he got the notebook, and began writing in it as well.

This time, It took him quite a while to finish it all.

Only then, had he finally rested his eyes, at the same time, deactivating his Sharingan who has been on the run throughout this whole time.

Making his eyes extremely tired.

Though as much as he wanted to rest already, he didn't have the luxury to do so.

So he quickly stood up and made some preparations for his next action.

After finishing, Kayn changed into casual clothes and left his room.

"It's still early, I had time to get to the forest and get familiar with this body."

Although Kayn received the memory of this body, operating it with the same precision as the original operator of this body is an extremely hard task.

The same way as how you cannot perform a flying 360 spinning hook kick just because you saw someone on TV do it.

(AN: Not sure whether that kick exists or not.)

That's why Kayn has to go and warm up his current body in a nearby forest, whether he's up for it or not.

Besides, if his memory serves him right, a meeting, the same meeting he's planning to attend to, will be happening later.

If not now then, he might not get a chance to train and familiarize his body anymore.

Well, with what he's planning to do in that very meeting, it's pretty logical to expect that.
