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...

He transmigrated into the Marvel universe, becoming a man with a mortal body who rivaled gods. Unfortunately, at this time, Tony hadn't yet forged his Iron Man suit and was imprisoned in a cave, his life hanging by a thread. Fortunately, he awakened a system, directly inheriting the Shadow Kingdom. He devoured the demonic energy of eight great demons, controlled ten Shadow Legions, and possessed twelve talismans! From then on, Marvel no longer had Iron Man, only a shadow overlord embracing eternal night in the light!

Dongfang Hao transmigrates to the world of Jujutsu Returns to War, awakening the Mangekyou Sharingan at the start, which contains multiple eye techniques: Amaterasu, Kagutsuchi, Kamui, and Tsukuyomi.

His arrival brought an unprecedented boom to the world of sorcery.

During my time at a vocational college.

Gojo Satoru: "I never imagined that besides my six eyes, there would be someone else in this world with a pair of special eyes!"

Xia Youjie: "Because you are Dongfang Hao, you are the strongest. Or is it that you are the strongest, and that is why you are Dongfang Hao?"

Lu Suo: "One Six-Eyed was enough for me, and now there's another one, Dongfang Hao!"

Rime: "Lord Sukuna, you said you would win, didn't you?"

...

The introduction is insufficient; please read the main text.

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!

Transmigrating into the world of Naruto, becoming an ordinary member of the Uchiha clan before the massacre, Uchiha Canghe obtains the [Strongest Character Role-Playing System].

Starting template – Five Insights! In heaven and on earth, I am the only one worthy of respect!

[Synchronization rate 10%, unlocking the Spell Rotation - Azure!]

Elder Uchiha: "This child has no respect for his elders; according to clan rules, he should be disqualified!"

With one hand in his pocket, Cang He razed the Nanga River Shrine to the ground with a single "He": "Old man, are you trying to teach me how to do things?"

The Third Hokage: "Damn it! He packed Danzo's Root into a ball and threw it into my office!"

Uchiha Itachi: "My Sharingan... why can't I see through him at all? This power has transcended the realm of ninjutsu!"

Orochimaru (fanatical): "This is art! A severed arm regenerates instantly! Canghe-kun, please let me study your body!"

Kaguya: "What kind of technique is that? Why can't my All-Killing Ash Bones ever touch you!"

A night of genocide? I alone am an insurmountable barrier! A coup? That's children's play!

The domain unfolds into "limitless emptiness," and even the Six Paths of Pain can only be completely overwhelmed by the torrent of information!

Several years later, the Fourth Shinobi World War broke out.

Standing atop the "Konoha Branch of the Jujutsu High School," Uchiha Sokō looked down at Naruto and Sasuke diligently training their "jutsu power," and a capitalist smile appeared on his face: "Give it your all, the future of the ninja world rests on your shoulders."

Chu He joined the Abyss Will chat group, entered the myriad worlds, and became one of its members.

To become a great will of the abyss world, a synonym for depravity, destruction, slaughter, and bloodshed.

By invading a world, dragging it into the abyss of depravity, and merging it with oneself, one can advance the world's rank and continuously grow stronger.

Upon becoming a demon king, Chu He possessed the ability to destroy planets with a single thought, and commanded countless demons, including demon kings, demon lords, eight-armed heavenly demons, flesh-and-blood worm demons, demons with the eyes of a thousand demons, and so on.

Furthermore, he awakened three of his own innate talents. In an instant, Chu He, whose ambition continued to swell, looked at the entire universe with a greedy gaze.

Intrusion, intrusion, and more intrusion!

Slaughter, slaughter, and more slaughter!

Depravity, depravity, and more depravity!

The myriad worlds have decayed; only by falling into the embrace of the abyss of depravity can they be reborn!

That is the ultimate destination of life.

From that moment on, an abyssal will that made all the heavens and myriad realms tremble was born.

The truly great will of the abyss has appeared!

More than 400 years ago, in X777, Lyle was a knight who protected Queen Irene.

In this era, dragons held absolute dominance and posed a serious threat to human survival.

Lyle awakens a future simulator. After simulating his future with Eileen, he discovers that he will die to protect her, while Eileen, due to a political marriage and prejudice, ultimately meets a tragic end.

The simulation ended, and Lyle received the "Dragon's Blessing," which has a threatening effect (the blessing can only be obtained in the first simulation with the same target).

Lyle decides to change his and Irene's fate, to change Belserion's fate of dying in battle, to change Kyoka and Sera's fate of blindly pursuing killing, to change Mavis and Zera's fate of painful separation, and to change the fate of many more Fairy Tail characters over the past 400 years...

Evan transmigrated to the world of Fairy Tail. He arrived very early, only a day after Natsu joined his guild. This world was dangerous, with accidents possible at any moment; yet it was also wondrous, scattered with countless precious and alluring treasures. Weary of the mundane, Evan quickly integrated into this world. Although things didn't go smoothly at first, he steadily progressed. He witnessed the destruction of a village, experienced stories of blood and tears buried deep in darkness, met the Mirajane sisters in a village haunted by demons, became a rising star amidst lightning and thunder, and together with Natsu, wrote a new chapter in history.

The protagonist travels to the Marvel universe, becoming the eldest prince of Asgard, obtaining the template of 'King Gilgamesh', and having twelve Gold Saints serve under his command.

He established the twelve zodiac signs and took charge of Valhalla.

Facing his sister Hela, Thanos, the head of the family planning office, solemnly declared: This is the king's domain, and it is not for ants to bark and howl!

[Inspired by watching the movie 'Legend of Sanctuary', since Asgard has both a Sanctuary and Valhalla, I'll just add them all. This is an invincible novel, so please don't be offended if you don't like it.]
