He traveled through time and became the cousin of Nara Shikamaru of the Nara clan in Naruto. Nara Shikahaku has a deductive transformation system. He said that although his chakra attributes are not enough and he does not have a special bloodline limit, he has a family secret technique.

What? You're saying the shadow isn't that long? The blood vessels in the human body are about 100,000 kilometers long. So, it's scientific that my shadow would become thinner and longer from the Fire Nation to the Water Nation, right?

Killing from a distance? Doesn't Shadow Seam allow you to concentrate chakra and thrust to kill? What? How do you break through the Lightning Release Chakra Coat? Doesn't Shadow Slap Technique increase strength?

How do you control the tailed beasts? Isn't the most basic shadow imitation technique enough? It's common sense that shadow imitation can freeze the body, right?

How can I defend against the Tailed Beast Balls alone? Gaara can use sand to defend himself, and the Raikage can also use chakra cloaks. Isn't it reasonable that my shadow can transform into a barrier?

Don’t disbelieve me, this is really a secret technique passed down from my family.

An accident led him to the world of Naruto and he became the future of the Uzumaki clan. What kind of secrets did Konoha hide? Was the second and third generation the murderer? These things had to be investigated one by one.

You want to destroy the world, fine, but let me see if I, Xuanwoyun, agree. If not, then go back home.

[The Subverter of Arbitrary Plots] [Brain-Blowing] [King of Stamp Collecting] As a player with a Resurrection Coin, Makoto stood atop the mountain, grinning wildly at the Five Kage: "Who dares to kill me? Who can kill me? I can do whatever I want!" — On Konoha's busiest street, the Third Hokage, Sarutobi Hiruzen, blushing, was forced to perform a monkey show. — Danzo Shimura, the public enemy of the ninja world, forced to dig deep underground, refusing to show his face, having shouldered so many accusations. — Makoto teased Uchiha Obito: "Rin, you're truly gentle." "You've already got your death!" Obito roared, his eyes bloodshot, panting. Makoto slowly pointed to the village entrance: "Don't get excited. Go to the village entrance and take two Tailed Beast Balls. Calm down, calm down." ... Konoha Spring. The supreme outer demon, the only Fourth Calamity, the wholesale source of ninja fun...

My name is Tokiwa Sougo, but I am not the little devil king, nor the old devil king. I am Tokiwa Sougo who traveled to the world of Naruto. I had no inheritance and felt that my life was over. But when I was just five years old, my complaints were heard by the old devil king, and I got an unexpected inheritance.

Tokiwa Sougo: I'm not a knight, I'm a demon king.

The story begins in a bloody mist.

The orphan Bamboo Cutter, slain by the Kirigakure Anbu, rises from the sea of ​​blood and corpses.

Her mutated gray Byakugan and the combined offensive and defensive Shikigakure (Shikotsu) combine to create the uncanny ability to manipulate her body, setting her on an inhuman path to becoming a physical ninja.

The Shikotsu strengthens her bones, the Byakugan manipulates chakra and her body, the Lightning Release Chakra mode strengthens her body, the Reverse Eight Gates replenishes her life force, she devours the Tailed Beasts to gain an infinite source of power and the Tailed Beast Coat, and possesses the indestructible power of the Monkey Demon... A beautiful girl, as delicate as a doll, becomes an inhuman physical monster.

The ultimate crushing of stats and mechanics, the terrifying contrast between her appearance and combat style, creates a Gokudo Hokage filled with blood and flesh.

Upon arriving in a fantasy world, Ryan unexpectedly discovered that his cheat code wasn't a skill level gauge, but one that allowed him to slay monsters and collect their bloodlines. ...The original black and white portrait suddenly transformed into color, and the goblin icon suddenly came to life. From its mouthful of fangs to its drooling saliva, everything was so vivid that it felt as if the goblin had come alive. Before Ryan could think about it, he suddenly felt his muscles tighten, and at the same time, his lower abdomen... "This..." He was a little confused, and the corner of his eye glanced at the attribute bar again: [Name: Ryan] [Occupation: Farmer] [Blessed Bloodline: Common Goblin Bloodline] [Bloodline Talent: High-Speed ​​Reproduction lv2... Agility lv1...] [Strength: 5] [Agility: 5 (+1)] [Constitution: 5] [Intelligence: 7] [Perception: 5] [Charm: 5]... Then, he looked at those powerful or mutated monsters with eyes that were not filled with the fear and dread of ordinary adventurers, but full of expectation and hope...

[In version 1.00, we added the setting of "light" to the world, so there is light. ]

In version 1.65, we have reduced the range of the Old Gods' activities. Now the gods can no longer walk on the earth and can only exist in the version DLC "Kingdom of God".

In version 2.43, we've closed the path to refuel the Primordial Furnace, and the initial flame that continued through the Age of Gods is about to go out.

In version 3.56, we've weakened the potion sequence's ability to absorb mystical traits. The success rate of the Sequence Zero Apotheosis Ritual will be infinitely close to zero.

In version 4.00, we've added the "Dissolution of Illusions" and "Personal Reality" settings for all humankind to help completely dissipate the mystery.

In version 5.10, we've eliminated the "Unknowable Realm" and added more knowledge singularities to advance the Age of Stars. Now, using FTL technology, you'll have the opportunity to meet the "Star Gods" during interstellar warps.

"At the beginning of the Fourth Epoch, the all-knowing Athena, then president of a giant corporation, hacked the world with the [Anti-Mystical Equation]. From then on, mysteries faded, and all transcendental fantasies fell into the dust of history."

At the beginning of the Third Age, the fortieth millennium of the Age of Gods, Ron stood alone on the spire of the Royal City, facing the Old Gods who had caused the catastrophe in the Fog City, and activated the [Anti-Mystery Equation] on his brain-computer interface.

In an instant, the fog dissipated, and the giant shadow of the old god shattered like glass hit by a sledgehammer, leaving only the clear blue sky.
