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."

Having spent many years in Naruto, he diligently trained, but due to his ordinary talent and lack of system assistance, he could only become an ordinary special Jonin of Konoha. This was probably the pinnacle of Gen Takuno's life. But... Gen Takuno looked at Hiruko, who was attacking Kakashi who had just obtained the Sharingan. It seemed that everything had reached a turning point in his fate. Oni-Garra Technique!

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!

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.]

[Second Side Mission: Spread Your Fame Far and Wide, Do Something Great and Shake Up the Ninja World.]

[Side Mission Three: Propagation and Restoration of the Uchiha's Glory - It is Our Inescapable Duty.]

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.
