Uchiha Kai: "I'm a hapless guy who traveled to the ninja world. The system is a sham used to make games and train me to be a super game producer. What kind of suffering is this?!"

System: "After testing, this is the earth in 2024. Please complete the production of the first game as soon as possible."

Uchiha Kai: "Okay, okay, you want to play it this way, right? Okay, since I'm not having a good time, let's use the Uchiha way to make the world feel pain!"

"The underworld game, start it for me!"

From then on, the ninja world had an old Uchiha thief who used the Sharingan to make the underworld game to avenge the world.

The beginning creates great fortune and the protagonist travels to another world.

Qin Zhou traveled to the world of Food Captives and joined a chat group, where familiar group members were.

Xia Chen unexpectedly transmigrates to the world of One Piece, activating the story island check-in system right from the start.

"What? You get stronger just by clearing story islands? Doesn't that mean you're about to take off?"

Upon visiting the first island, Windmill Village, I obtained the Zoan-type Mythical Beast Fruit, the Great Sage Equal to Heaven form!

Is Nika the Sun God really that powerful?

Do you know that even if you become a god, you're just one of the 100,000 heavenly soldiers and generals who can stop me?

He then happens to meet Luffy, who is just about to set sail, and at Luffy's invitation, becomes the vice-captain of the Straw Hat crew.

Even though he has awakened the "Wish Magic", Noah can only fulfill the wishes of others.

[Natsu wants to eat meat, the reward is fire resistance]

Xiaoyu wants some pocket money to buy a Super Moose plush. The reward is the Shadow Queen's blessing.

………

After responding to other people's wishes countless times through the "Wish Magic", Noah suddenly realized that he was standing on top of the world.

And all of this started from that bustling magic guild.

Yun travels to the world of pirates.

At the beginning, he faced the life and death selection of the Rocks Pirates.

Fortunately, I have awakened the golden finger: my comprehension is beyond belief.

[Through eating, you gain insights and comprehend the Cell-Eating Art.]

You watched Kaido display Armament Haki and Observation Haki, and suddenly gained an insight. You learned Armament Haki and Observation Haki... Through deduction and creation, you successfully created Armament Haki: Divine Armor and Observation Haki: Divine Sense.

[You awakened Conqueror's Haki...successfully comprehended Conqueror's Haki: Kamui, and created a Conqueror's Haki training method.]

[You consumed the Shadow-Shadow Fruit, triggering a sudden burst of intuition and realizing the fruit's hidden power... You developed the Shadow-Shadow Fruit's ultimate hidden form—the Shadow-Shadow Fruit, Mythical Beast, Darkin King form.]

[You create a Devil Fruit fusion...]

Devil Fruit Fusion, Devil Fruit Evolution!

The pinnacle of physique, the ultimate dominance, and unparalleled swordsmanship!

With his extraordinary understanding, Youen created a different world of pirates.

In the Cross religion, God is the only one, and all miracles are in the hands of the one and only God;

The “right side” of God, in the Cross religion, means “equal to God”;

The ‘Demon God’ in the forbidden, the ‘beast’ in FATE, the ‘Gods of the gods’ of the godslayer, the ‘Witch Cult’ from zero, the ‘Final Trial of Humanity’ in Hakoniwa…

This is a story of transmigrating into the son of Aleister Crowley, the ‘world’s most evil man’, waving his right hand, and ascending to the God of Crusades.

“The magic name ‘BEAST’ 777 means ‘I will overcome the evil of mankind’!”

(Half-funny + scheming + satisfying + doesn't fawn over Konoha + semi-invincible + many girls)

The original female characters who were saved: Mikoto Uchiha, Tsunade, Kushina Uzumaki, and Nono Yakushi...

The protagonist is reincarnated into the Naruto world, and after unraveling the mystery of his birth, he discovers that he has become an adorable Uchiha boy and obtains the Blacksmith System.

In the early stages, he distributed weapons in Konoha; in the mid-to-late stages, he left Konoha and distributed weapons throughout the entire ninja world, watching others get beaten to a pulp.

When others use his weapons, he can also gain the attributes, abilities, talents, ninjutsu, and bloodstains of those people.

Moreover, all those who died using his weapons or were killed by his weapons were taken into his Temple of Death.

They only care about fighting, not putting in any effort; they'll just be brothers inside the Ten Thousand Souls Banner!

Ahem, in short, this is a joyful (death-seeking) journey where ten thousand Ambers travel through each other at the same time and can share all the power.
