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!

Is the Uchiha clan facing intense competition? Is the Ninja World War intensifying? Uchiha Gen declares: "I can't keep up, I'm giving up!" After activating the "Lazy System," he abandons rigorous training and frantically increases his strength through sleeping, daydreaming, and slacking off. His three-tomoe Sharingan has already awakened, he wields all five Fire Release techniques with ease, and he has mastered the Six Styles of the Navy. In Konoha, where everyone strives to be a hero, this "useless" Uchiha is quietly transforming into a behind-the-scenes mastermind who will change the landscape of the Ninja World.

[Multiple female leads + semi-invincible + slow-burn, hoarding type + rejects bloodline dependence]

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!

We've transmigrated into the Naruto world, becoming an insignificant member of the Uchiha clan. "Though I am but a lowly mortal, my heart still soars to the heavens!" Our goal: to fly up and stand shoulder to shoulder with Kaguya Otsutsuki!

He was transported to the Naruto world by accident and discovered that he had gained the ability to absorb energy. So he went further and further down the path of searching for and absorbing others.

He absorbed Uchiha Shisui's corpse, gaining some chakra and some ocular power, and acquired the Mangekyou Sharingan, Kotoamatsukami!

Absorb Hashirama's cells to gain a large amount of chakra, and unlock the Wood Release bloodline limit!

He absorbed Naruto's blood and gained the Uzumaki physique and Ashura Chakra!

When he absorbed everything and achieved the title of strongest, the ninja world finally ushered in true peace.

That year at the Valley of the End, Hashirama Senju faced Madara Uchiha, and Madara Uchiha was ultimately defeated.

Later, I saw Madara Uchiha with tubes inserted into the back of his neck, playing tricks and schemes, showing none of the heroic spirit of the Asura of the Ninja World. This scene is unforgettable for me.

At that moment, I thought, if I could become the head of the Uchiha clan, I would definitely do what Madara Uchiha couldn't do.

Now that the position of clan leader is within my grasp, I must consider whether this might be the only opportunity I have in my life.

I believe that Madara Uchiha played a crucial role in the Uchiha clan's past dominance, but now it's my era.

Restoring the glory of the Uchiha clan is our bounden duty!

Uchiha Jin, a transmigrator.

Knowing the plot but lacking a system, he only wanted to remain a nobody. He even prepared in advance to learn about governance as a way out, hoping to take his parents away before the night of the extermination.

Unexpectedly.

Danzo captured his parents in order to collect Sharingan eyes, which caused Uchiha Jin to awaken his Mangekyou Sharingan on the spot.

hehe.

Do you really think he, a time traveler, has no temper?

As a result, Uchiha Jin completely changed his plans, joined the Uchiha clan, confronted the Konoha leadership head-on, and began his journey to seize power!

As a virtual anime game player, for unknown reasons, he actually entered the Naruto world. Treating the entire world as a game, Hyuga Akira plunged headlong into it. The [Bandit Set] dropped by bandits made his stun skill dominant in the early game. The [Sharingan] dropped by Konoha created a synergy with the Byakugan. He obtained Demon Slayer [Lightning Breathing] and Baki [Demon Back] and [Demon Brain] from Cloud Village. He also obtained Fairy Tail [Arc of Time] and [Fire Dragon Slayer Magic] from Iwagakure. He picked up the [Devil Fruit Fragment] dropped by Kirigakure. Wearing the [Vongola Sky Ring] from Sunagakure, the flames of his fighting spirit ignited. As experience points accumulated...

Having transmigrated into the Naruto world, Makoto Aoki becomes a homeless child struggling to survive in the Land of Rain. After finding a Devil Fruit from another world, he swallows the power called "Azure Dragon," and also swallows the karma that will overturn the entire ninja world.

As the shadow of a blue dragon, obscuring the sky, hovered above the Land of Rain, Hanzo of the Salamander, hailed as a "demigod," asked in terror, "Are you here to destroy the Land of Rain too?"

Long Tong remained indifferent, but his answer astonished all who heard it:

"No, I just came here... to collect trash."

From then on, the ninja world had one more unconventional figure.

The Akatsuki organization viewed him as the "Blade of God" who would bring about change, Madara Uchiha listed him as an "unexpected variable" that had to be controlled, and the Otsutsuki who descended upon him sensed a threat from another realm in him.

However, Makoto Aoki had no interest in the so-called salvation or destruction of the world.

He only wanted to use this power, comparable to that of gods and demons, to build his ideal home on the ruins.

While the five great nations and the Akatsuki were locked in a life-or-death struggle on the battlefield, he was busy smelting steel with dragon breath, forging energy with thunderstorms, and clearing away ruins with hurricanes.

When everyone finally realized that this "garbage collector" was the one who could truly influence the fate of the world, he was already standing in the floating city he had built, overlooking the entire ninja world.

"Destroy the world? That's too boring."

"My dream is to rebuild it with my own hands."

This is the story of a dragon determined to become a "creator" and his irrational conquest through "infrastructure construction".

[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.)
