Kato Dan, a Konoha Jonin who died on the battlefield, was not allowed to enter the Pure Land; instead, he was bound to the Death God System.

Awaken your Zanpakuto, gather the dead, build the Soul Society, and reshape the order of the dead.

"What? The 'corpse demon' in the Corpse Demon Seal is actually a spirit-eating monster?"

"It's alright, I have countless prospective Grim Reapers backing me up."

He ignored the system's warnings about not interfering with the living world.

"If I become the Grim Reaper and then ignore everything, wouldn't I have wasted my life?"

The creation of the Gotei 13, Nawaki, Sakumo Hatake, Sasori's parents, and the longing of countless dead souls for their loved ones.

"The final resting place of the deceased is defined by me!!"

Death God vs. Ninja, Ninjutsu vs. Kido, Chakra vs. Spiritual Power

Behind the scenes of the ninja world, countless 'people' are watching.

Then let me, the Grim Reaper, reshape the ninja world!

From today onwards, this world will be renamed the World of Death.

Those who peer into the world of death will be peered into by death itself!

If your eyes could see small print a kilometer away, see everything around you, and even see through everything, how would you use them? That's right, I'm talking about the Konoha Byakugan. Just looking at the lore, every Byakugan user is practically a wide-area human radar. To put it poetically, it's a bloodline limit; to put it bluntly, it's a cheat code—the kind that would get you banned in any game. In a fighter jet battle, if your radar is twice as strong as the enemy's, you can use them as target practice, and some might even be unable to leave the airport. So how should such a talent be used? The Hyuga clan's choice is to engage in hand-to-hand combat, specifically close-quarters combat. Isn't that like fighting in close quarters while wearing binoculars? Every time I see this idea, Hyuga Chomei feels a wave of dizziness…

Transmigrating into the Uchiha clan and becoming bound to the relief system.

When the tragedy of the original story unfolds, Uchiha Senche descends with the power of all the heavens.

——————————

On the night of the Nine-Tails' death, just as its claws were about to strike Minato and his wife, young Obito and Kakashi descended from the sky: "We're not too late, are we, Sensei!"

As Jiraiya infiltrated the Land of Rain, his consciousness waned. He sighed, "Always just one step away," when a familiar voice rang in his ears: "How pathetic, you stinky toad."

On the night of the massacre, Itachi entered the room with his sword, only to find two Fugakus sitting in the center, with Shisui beside him questioning, "Uchiha Itachi, what exactly did you protect!"

[Cross-Dimensional Rescue]

In the Infinite Castle, the hundred-meter-tall Susanoo made Muzan doubt his own existence: "This is the true god, the Uchiha—the God of Destruction!"

At the summit of Bailing Mountain, the quintessence flowers, like a kaleidoscope, vanish in reverse.

On the streets of Tokyo, the demon returns to his sanctuary: 'You should go back to school, Reise.'

Content will be continuously updated; I'll write whatever readers suggest for the next chapter.

[Plot destroyer] [Detail enthusiast] [Respectful of the original work]

Special note: This is my first book, so the pacing is a bit slow. Sorry.

The preceding storyline mainly lays the groundwork for the Third World War and showcases the normal growth of strength. If you want to see the dungeons, you can skip directly to Mist Hidden - Kaleidoscope.

The main reason is that I feel I don't have the class or the ability to go wild without using a kaleidoscope.

She transmigrated into the Naruto world, only to become Sakura Haruno. After drifting aimlessly for five or six years, she finally realized she had no system, no cheat codes, and no special abilities—a complete "three-nothing" transmigrator. Was she destined to become a mere foil to Naruto and Sasuke, a laughingstock among the new Three Ninja? No! Who says a commoner can't rise to power? In the original story, she became a Kage-level ninja; as a transmigrator, she would only be stronger! Thus, determined, Sakura Haruno began her relentless pursuit. Ultimately, relying on her extraordinary genjutsu talent, she stood atop the ninja world.

When Gu Yuan woke up, he found himself transported to the Naruto world. Due to a traitor's betrayal, he was now the only surviving member of his family. Fortunately, his parents and his senior sister, Kurenai Yuhi, had a close relationship, and Kurenai took him in. She discovered his special ability as a transmigrator—the ability to enumerate all possibilities. As long as he could set variables and conduct practical deductions, he could obtain the desired result.

As he gradually calmed down, he forgot the cruelty of the ninja world. It was only when the night of the Uchiha massacre approached that he realized he was about to lose his friend Uchiha Ryūna. In order to find a way to save her, he overexerted himself and fell into a coma while performing mental deductions. When he woke up, it was too late, and he didn't even get to see her one last time.

Worse still, the overdraft caused problems in his ability-advancing mind lab. Only when he experienced a complex emotional state that resembled both romantic love and familial affection could he utilize his computing power to the fullest extent and complete the unfinished blueprint for the life ninjutsu...

He had no choice but to target his childhood sweethearts, planning one confession after another, but all of them failed due to unforeseen circumstances. Just when he was feeling disheartened, he discovered that the girls actually had quite a few feelings for him...

The world has always been a place of survival of the fittest, and he chose to do his best to pursue his goals, leaving the rest to fate.

Self-defense accessories, tactical units, automated puppets, ninja life forms...

The desire to protect everything pointed him in the right direction, and the fusion of emotions fueled his inspiration, gradually giving him the power to challenge the entire world.

Gu Yuan: To hell with bloodlines and eye transmission! As long as I can set variables, I own the whole world!

I made a wish to my great-great-great-grandfather: to live out my days in Naruto. My great-great-great-grandfather was incredibly kind; he gave me an invincible scratch-off lottery shop. My name is Wu Di, and I am invincible.

[Naruto + Time Travel + System]

A physics graduate student is transported into the world of Naruto, becoming a member of the Uchiha clan on the eve of their massacre. Uchiha Ryo awakens the [Entry System] and begins to use science to revolutionize the ninja world.

The Great Fireball, equipped with [Nuclear Fusion], is a small sun rising in the palm of your hand; the Chidori, equipped with [Electromagnetic Cannon], is a beam of judgment piercing the sky; the Flying Thunder God, equipped with [Space Fold], makes the ends of the earth seem near.

As terms such as "quantum tunneling," "information disruption," and "the law of entropy increase" are unlocked, the so-called bloodline limits and the Sage of Six Paths are nothing more than old legends waiting to be deconstructed.

(Although the background of this book is Naruto, the protagonist is Uchiha Ryo, and it is a completely new storyline.)

[Female Frequency + Reincarnation of Naruto without Memory + Infrastructure Flow + Daily Life + Resetting the History of the Five Great Nations]

For future generations, this may be the best era:

Hashirama Senju and Madara Uchiha shine like the sun and the moon, Tobirama Senju and Izuna Uchiha shine like stars in the world, civil wars break out among the small countries on the Fire Continent, religions clash endlessly on the Water Continent, emperors come and go in succession on the Earth Continent, the indigenous people of the Wind Continent are sold into slavery, the East Tea Company in the Tea Kingdom makes huge profits, and the discovery of the Thunder Continent brings abundant silver to the world.

Everyone knows that this is an era that belongs exclusively to the strong, and the weak are only worthy of being vassals of the strong.

But Asagao just didn't want to become a ninja, and she didn't want to put her husband's surname in front of her name, even if that surname was Uchiha or Senju.

Could it be that... non-ninjas are not worthy of living in the Warring States Period?

——She wanted to find the answer herself.

Reborn as a member of the Uchiha clan, Homura opens her eyes to find the countdown to their annihilation underway. While other clan members still cling to the power of the Sharingan, Homura sees only cold, hard data and a dead end.

As a strategic analyst in his previous life, he transformed his bloodline limit into a "database," reshaping his clan with a modern management system. Escaping Konoha was not a defeat, but a strategic retreat calculated with meticulous planning; establishing a new nation relied not on brute force, but on overwhelming power through technology, institutions, and ideology.

From a pawn of Konoha to a player, and then to the creator of new rules. While the ninja world was still immersed in old hatred and illusions, he led the Uchiha clan to burn away the decay with the fire of reason, creating a new order on the ruins that could last without the sacrifice of heroes.

This is the most rational reborn individual, launching the ultimate rebellion against fate.
