"So, the reason of Sharingan going from one magatama to two magatama and then three magatama a genetic mutation or something else?" Looking at the test subject in front of him, Kenichi Amemiya showed a look full of curiosity.

"...I always feel that the way this disciple looks at me is not right." Orochimaru held the "Research Report on the Effects of Soul Reincarnation on the Body" submitted by Kenichi Amemiya in his hand, his face

unsightly.

【Reincarnated as Dudley Dursley + Power of Logic & Strength + Fixing Canon Regrets + Power-Up via Magic Item Fusion + Straight Talker (Honest and Open Schemer) + Light System (Low Presence) + No Female Lead】

A bold and street-smart man from Blue Star reincarnates into a parallel Harry Potter world…

…as none other than Harry’s infamous Muggle cousin—Dudley Dursley.

By fixing key regrets in the original story, Dudley earns the right to fuse magical items, cleverly balancing brute force and sharp reasoning, evolving from a simple Muggle into a Concept-Level Archmage.

From there—

The Savior’s dark childhood is lit by a light so twisted it loops back to righteous.

The half-giant’s beloved dream of dragon-riding becomes reality, soaring over the Forbidden Forest.

The sweet-toothed old bee (Dumbledore) stops doing faith leaps from Astronomy Tower.

The prideful little dragon (Draco) embarks on a new path of growth, with friendship taking center stage.

The venom-spitting bat (Snape) is no longer misunderstood, but ends up tasting an even deadlier venom himself.

The pink toad (Umbridge)… actually becomes a literal pink toad.

Hogwarts undergoes sweeping educational reform.

The deeply cherished dead return from beyond the Veil.

And the brutal war that didn’t even spare the birds becomes a one-sided steamroll—with full counterattacks stacked to the max.

Shako, a seasoned office worker, accidentally died from electrocution while slacking off at work and watching One Piece. His soul was transported to the One Piece world and he was rescued by Whitebeard. He eventually recognized the pirate as his father, changed his name to Shako, and became Edward Newgate's eldest son and the vice-captain of the Whitebeard Pirates.

Shaq: "Hahaha, that old devil Im's era was called Whitebeard!"

Whitebeard: "Gurarararararar, what do I, an old man in my seventies or eighties, know? If you have something to say, go talk to my good-for-nothing son."

Decades after Whitebeard reigned supreme over the seas, people were astonished to discover that this old man showed no signs of aging. Even more terrifying was that if anyone coveted his throne, they would be met with devastating attacks and the whispers of a demon.

"Hahaha, what kind of Tom, Dick, or Harry dares to disrespect my old man?!" (The synopsis is insufficient; please proceed to the main text.)

Jiang Chen traveled through time accidentally and began his journey in anime.

The world is tentatively determined to be: Naruto - Attack on Titan - Demon Slayer - Sword Art Online - Detective Conan, etc.

————

In the Naruto world, Jiang Chen obtained a system that gives him a 10,000-fold return on his disciples. As long as he teaches his disciples, he can get corresponding high-fold return rewards.

As a reward, Jiang Chen taught Hinata the black coffin of the ghost way that he brought from the world of death.

During the Chunin Exam,

Neji: "Give up, Hinata, you are not fit to be a ninja."

Hinata: "I don't want to run away anymore, Neji-nii, let's have a showdown! A faintly turbid emblem reveals an unruly and arrogant talent...Hadō no 90: Black Coffin!!!"

Everyone: "She calls me brother, but she kills me. This girl is so scary!"

Shangguan Mo traveled to the Naruto world due to an accident.

In times of crisis, the system that can synthesize summoned beasts was activated.

…

[Stone] + [Earthworm] = [Earth Dragon]

…

[Sharingan] + [Crow] = [Scarlet Moon]

…

[Asura Chakra] + [Anaconda] = [Immortal Xiangliu]

…

[Ichiraku Ramen] + [Chimpanzee] = [Otsutsuki Ichiraku]?

…

Gradually, Shangguan Mo discovered the joy of synthesis.

The five major countries: You’d better behave yourself!

Shangguan Mo: I've traveled through time, so what if I just want to be a shadow?! ?

In Naruto, you should tam beasts!

Psychic Beast: Master, stop looking, come down and join the team fight!

Shangguan Mo: Fight in a group? What group? I will never fight in a group in my life!

Summoning beast: Master, Minato Namikaze wants you to get down, he wants to kill you!

Shangguan Mo: Tsk! As for him, it would be better to call his son!!!

Psychic Beast: He said his son is only two years old...

[The Dimensional Life System allows you to experience different lives without leaving your home] [Warm Tips: Because the "Real Life" mode is a real journey for the host, there are certain risks. It is recommended that the host choose the "Virtual Experience" mode for the first experience.] "Is there a risk?" After hearing this, Uzumaki Naruto's eyes lit up slightly: "That's it, I choose the "Real Life" mode!" [Special Tips: The "Real Life" mode is a real journey, there are certain risks. For the host's first experience, it is recommended to choose the risk-free "Virtual Experience" mode.] "I don't accept your advice!" Uzumaki Naruto completely ignored the system's prompts, excitedly clenched his palms, and punched hard, saying: "I will choose the risky "Real Life" mode, let's get started!"

Suffering from cancer, but when he traveled to American comics, he showed his true skills!

What? It’s the Marvel Zombie Universe?

Seeing the zombie heroes rising into the air in front of him, their tongues flailing about to eat him alive, Bai Ye smiled as he stepped back and closed the door of time travel: "I won't disturb you, I'm leaving~"

Medical skills and Taoism, that is where my interests lie, I am willing to save souls who are confused and suffering, and contribute a small amount to the prosperity of the entire soul world...

Of course, if medical skills are no longer able to restore the Soul Soul Realm, then perhaps drawing the sword is also a good choice.

Everything in the sky - the birth of the tree world!

(PS: Not pure invincible flow...)

After traveling through the world of Naruto and seeing through the increasingly corrupt darkness of Konoha in the Elders' Group, Xuan Che decided to withdraw from the struggle circle and live in seclusion in the mountains.

However, he did not slack off in his practice, and continued to break through the bottleneck with the help of the [Dimensional Evolution System].

Twenty years later, a nephew of Wuwukai came to him and claimed that Xuan Che's cheap brother had failed in his mission and was in a strange state recently...

Ling Feng (Senju Ling Feng) awakens the Naruto Pirate Shuttle System.

At the beginning, you enter the world of Naruto and obtain the natural-type Sen Sen fruit.

Blackbeard: I waited my whole life, but I couldn't get the Dark-Dark Fruit...
