[Konoha Memorial Monument, Sign-in: Perfect Sage Body + Eternal Kaleidoscope!]

[Valley of the End, Sign-in: Wood Release: True Several Thousand Hands!]

[At the Omni-King's Palace, sign in: The Law of Cosmic Erasure/Creation!]

The Nine-Tails' rampage? He held down the berserk Nine-Tails with one hand: "Behave yourself, don't disturb Kushina's rest."

The Fourth Shinobi World War? Black Zetsu: "The Eye of the Moon, which I've planned for a thousand years, has become his graduation ceremony for his students?!"

Minato Namikaze: "People call me the Golden Flash, but Yu is the only sun that illuminates the entire ninja world."

[One extra chapter for every five-star review]

Qin Tian traveled to the pirate world and obtained the Possession Teacher System, allowing him to possess the opposite sex and share their bodies. He possessed eight-year-old Nico Robin and raised a Thousand-Armed Ice Queen, who protected O'Hara! He possessed twelve-year-old Hancock and raised a Flame Dragon Princess, wielding dragon-slaying magic! He possessed ten-year-old Nami and raised a Weather Goddess, who presided over the Brilliant Sky Thunder Prison! ...

A novel revolving around being transported to another world with an op system. The mc spends his day chasing skirts and doing missions to level up. A standard journey to the top with lots of girls from various animes and games with a twist of that gaming feel (hunting mobs, doing missions).

Traveled through time.

Takro looked at his reflection in the water: a spiky head, a ten-year-old body, and a dangling tail...

Got it! A true Saiyan start!

With the system in hand, the world is mine!

Becoming stronger? Super Saiyan? Bulma on the left and Chi-Chi on the right? It's just around the corner!

However...

"Haki is also qi! I've practiced correctly!"

"Although I can transform when I see a full moon, I'm not a fur tribe!"

"What is ONE PIECE? What is One Piece? Where are my Dragon Balls?!"

......

Day 1 of the journey: The Dragon Ball world is too dangerous! Stay safe and develop!

Traveling through time: Huh? It seems just like that?

After traveling through time for N years: What kind of bugs are the Celestial Dragons? This is my Earth!

“From today onwards, you will become the Envoy of one of the Main Gods in the Dimensions of Gods. You will travel from one world to another and through that, you will attain what others will never obtain in their entire life.”

The moment these words echoed in Fang Li’s head, Fang Li’s life was destined to be extraordinary…

[Rocks Pirates] [Multiple Devil Fruits] [Multiple Female Leads] [Battle for Supremacy]

Fang Huo stumbled upon a stroke of luck and traveled to the Ancient Moon Village in the One Piece world. His soul cracked during the time travel, undergoing a special mutation and fusing with the energy of this world to form nine soul worms of the same origin yet independent.

With the first Soul Worm fusing with a Devil Fruit power, a user of nine Devil Fruits was born...

Moon-Light Fruit, Gravity Fruit, Vampire Fruit, Moo-Moo Fruit, Rumble-Rumble Fruit, Azure Dragon Fruit...

With Fang Huo's help, the Rocks Pirates appeared in the world ahead of schedule, possessing an unprecedented ultimate lineup...

Have you ever seen the Rocks Pirates, which included Red Earl, Roger, Rayleigh, and Jabba?

After traveling to the world of Fairy Tail, Roger obtained a game system that allows him to sign contracts with specific individuals, granting him and his contracted partner special magic. After signing a contract with Erza, the two of them both gained access to dress-up magic and additional magic. Defeating enemies also drops magical items and skills. The Honesty Pipe: Those enveloped in the smoke can't help but speak their true feelings. The Sadness Onion: Cutting it causes everyone within 10 meters to feel intense sadness and burst into tears. The Big Mouth's Prophecy Crystal Ball: Possess a crystal ball that can see into the past and the future, but beware: this crystal ball is quite gossipy and will accidentally reveal hidden details of the past based on its predictions. As the magic power of the contractor increases, Roger's magic power will also increase. Here you can see but not limited to: Lucy, a melee summoner who has learned the Star Clothes in advance, has sufficient magic power, and can form a team by herself; Mirajane, a demon with unlimited power to devour demons, who welcomes the gate of Hades in her prime; Erza, the swordsman who can drop armor and weapons when defeating enemies and has learned enchantment magic; Natsu who has the Burning Decree and has learned the God-Slaying Magic; and Roger, the almighty Magic King and the guild president who secretly controls the Council.

He travels to Konoha and becomes the sole heir of the Senju clan!

In order to revive the Senju clan, Senju Yosei decisively decided to marry Uzumaki Kushina and embark on the path of 'prospering the clan with many children'!

"Yo yo yo, aren't these the Uchiha clan and the Otsutsuki clan?"

"You've gotten so slender in just a few days?"

Bai Yu transmigrated to a crossover anime world, expecting a blissful, idyllic life, but suddenly found himself embroiled in a brutal death game. Survival Road, Ju-on, Final Destination... facing one challenging dungeon after another, his scalp tingled. Fortunately, he awakened a skill proficiency panel; by diligently upgrading his skills, he could continuously improve his abilities! Now, crisis had turned into opportunity! ... Yukino: One isn't enough, you want my sister too? Utaha: Black stockings or white stockings? Touma Kazusa: I want to join in punishing Mom too! Kuriyama Mirai: With you, I'll never be unhappy again.

The story begins with the Nine-Tails' rampage, but the protagonist instead goes to steal from the Fourth Hokage's house! Reincarnated into Konohagakure in the Naruto world, he's even a relative of Sakura Haruno! And a seemingly "ordinary" medical ninja at that. Watch how the protagonist uses his precognitive abilities to live a different life and save countless unfortunate souls…
