[Weak system, no system later + not a wish-fulfillment story + Uchiha + development + humor]

"Itachi, you are unfilial, disloyal, and unjust. It's not too late to turn back now."

"Obito, go back to Gotham. Batman says he's not going to fight you anymore."

"Danzo, you have abused your power for personal gain, your desires are boundless, and you have committed countless crimes that are unforgivable."

"Hiruzen, you have been too lenient with Danzo. You are unworthy of your position. Considering your past merits, you should step down."

"Tsunade, you don't want Konoha to fall into decline, do you... You're going to be the Hokage!"

"Orochimaru, I'm giving you a chance to start over. Wasn't everything before Danzo's fault?"

After a thousand years of suffering, the ninja world will, under the protagonist's leadership, move towards stability and prosperity.

Chiya: I've worked so hard for so many years to change the ninja world like this, isn't it all so that I can live a carefree and happy life?

This book is also known as: Konoha: Rebuilding the Glory of the Uchiha!

Tsunade, you've really had too much to drink!

Our family has fallen on hard times.

The once glorious Uchiha clan has been reduced to its last remaining descendant, you.

[Side Quest 1: Enhance your strength and uncover the truth behind the family's decline.]

Looking at the system in front of him, Tiandao wanted to shout, "Damn idiot! System, do you even recognize me as an Uchiha?"

However, looking at the rewards listed by the system: [Sharingan, Hashirama Cells, Sage Mode, Yin-Yang Release.]

"Since that's the case, then let me see your limits. System, activate it!"

Tiandao, born a commoner, is a mere transmigrator. Watch as he stirs up the ninja world with the help of a mentally challenged system.

(Naruto, System, Multiple Female Leads)

Staying up all night to rank up, I suddenly died and was reborn as Naruto Uzumaki.

This Naruto world is a bit of a trap:

Ashura's chakra is gone, my inherited talent from my parents is ruined, and I've become an even more disliked, gloomy loser than in the original story?!

Fortunately, I was bound to the "Naruto Mobile Game System" when I transmigrated.

Completing system tasks will earn corresponding rewards, allowing you to upgrade your rank, break through level limitations, and increase eight key stats: Ninja, Body, Illusion, Sage, Power, Speed, and Refinement.

then--

"I heard that you, Uchiha Itachi, can form six hand seals in one second? Sorry, I can form forty-four hand seals in one second. Having fast hand speed means you can do whatever you want."

"The God of Shinobi, Hashirama Senju, has more chakra than the Tailed Beasts? Interesting. I'd like to call you second, because I'm number one."

When the Otsutsuki clan descended upon the ninja world, and stared into deep thought as I conjured the Exploding Star Rasenshuriken I had just formed, all I could say was:

"As expected, being a Hokage is not as good as being a 3,000-point Super Kage."

He was Minato Namikaze's classmate, but the class's quietest member. He had no particular skills, and his lazy chakra prevented him from learning any ninjutsu. If nothing unexpected happened, he would become cannon fodder on the battlefield.

But—he has a cheat code! His chakra increases by 0.5% every day, and now he has one-tenth of a chakra, so the future looks promising!

I'll just focus on wielding my sword; the rest is up to the chakra!

When the Ten-Tails was born, he carried an invincible chakra and slowly raised his sword—Do you also want to dance?

Under my chakra, all ninjutsu is just flashy nonsense.

[Naruto Fanfiction + Invincible Build + Multiple Female Characters + Gojo Satoru] Descending into the Naruto world with 'Six Eyes,' becoming an anomaly within the Uchiha clan. The mysteries of ninjutsu are crystal clear to me, and the conspiracies of the world are utterly insignificant before me. Some call themselves chess players, others are content to be pawns. And I, lazily sitting outside the chessboard, hold the power of victory and defeat in my hands. I can turn the tide for the loser, or I can… completely overturn this game.

Are we the only one among the five great ninja villages that lacks money, resources, and geniuses?

You think you're so great! You're so arrogant! You say my Sand Village isn't worthy to be one of the Five Great Ninja Villages alongside you!

You all have two tailed beasts, but mine only has one!

If you can't beat Konoha, then come and beat me!

Just because I'm weak!

But let me tell you, what goes around comes around!

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!

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!

Han Guang: "My teacher is Minato Namikaze!"

"My teammates are Kakashi, Obito, and Rin!"

"And as the captain of Class 9, it's only reasonable for me to ask for favors, right?"

Nine-Tails: "Is this your reason for pinching me up?"

Danzo: "Why? You only threw one punch, but I lost nine lives?"

Hiruzen Sarutobi: "I've already abdicated, yet you're sending me to the battlefield?"

Madara Uchiha: "Impossible! I've already surpassed Hashirama, and you defeated me with a single punch..."

With a calm expression, Han Guang unleashed a punch at the moon from afar.

A terrifying force tore through space, stirring up violent spatial turbulence.

This strike was like a dark ray of light, shooting straight at the moon.

A moment later!

The moon exploded!

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".
