[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?

Both Shi Qiu's time travels are extraordinary.

One became a member of the Uchiha clan in the Naruto world, and the other became a member of the Pirate King's crew in the One Piece world.

The Naruto world.

Uchiha Shikichi wanted to change this messed-up ninja world, and his first step was to seize power within the Uchiha clan and occupy Konoha...

One Piece world.

Shi Qiu is a true pirate who abides by the rules of the pirate world and pursues power, fame, and wealth.

From a crew member to a legendary pirate, he gradually grows stronger and more powerful, ultimately achieving his ambitions...

Shuji Taketori: Plot? I am the plot! Jiraiya: To establish a heart for young girls, a destiny for young women, to carry on the family line for wives, and to bring peace to widows! Shuji is my life mentor! Kaguya Otsutsuki: I'm going to come out and beat my son! You two little brats, just you wait! Naruto: Shuji said, if they throw poop at me, I'll... I'll grab my kidneys and liver! Sage Art: Splatter - I'll grab my kidneys and liver! Sasuke: Nii-san~ Showing off is a bad habit, but I can't stop. I'm going to catch up with that person! Amataras! Madara: That's great! I acknowledge you! The Dance King from Konoha! This is a fun-loving story of a humorous person healing the dark ninja world.

Past, present, future, and destiny. These form the foundation of the world and represent the power of the present. The past is eternal, representing unchanging power. The present is the era, representing the strongest power. The future is potential, representing infinitely powerful yet infinitely weak power. Chosen by the past, one becomes the master of the unchanging. Chosen by the present, one becomes the king of the era. Chosen by the future, one becomes the emperor of the end and the emperor of hope. Chosen by destiny, one becomes the emperor of fate! The chosen youth ultimately embarks on the path planned by destiny. Not wanting to be bound by fate, he continues forward. If humanity cannot achieve this, then he will become a stronger being, until he becomes an ultimate existence that even gods cannot look directly at. The world is finite, but dimensions are infinite. Continuous battles lead to becoming the ultimate being. Becoming the master of destiny! The female lead is Yae Sakura (?ω*?). Worldline: Akame ga Kill! → Fourth Holy Grail War → Godslayer → Dragon Clan → Problem Child [First two volumes are for beginners, poor quality]

[Simulator + Multiverse + Invincible and exhilarating story + Fast-paced + Decisive and ruthless]

Lin Yu was completely bewildered.

He simply took a nap and inexplicably found himself transported to another world. Fortunately, after the transmigration, he merged with his counterpart in this world.

Based on his memories, he knew that he had probably transmigrated to a world where spiritual energy had just begun to recover.

Just as he was thinking about how to deal with the murderer who killed the original owner of the body.

His golden touch arrived as expected.

[Congratulations, host, on fusing with your counterpart. The Otherworld Simulator is now activated.]

This simulator can project a true spirit to form another self in another world and infinitely simulate the life of that other self.

After each simulation, Lin Yu is able to inherit the strength I possessed in the other world.

Okay, this guy went straight from being a background character in a spiritual revival story to becoming the protagonist of a wish-fulfillment novel in an infinite simulation story.

After that, he simulated one world after another: martial arts world, high-level martial arts world, world of gods and demons, world of immortals and heroes...

As Lin Yu watched the simulation, he felt that he was more like a protagonist in a wish-fulfillment novel than the other world version of himself!

Izumi transmigrates to a world where everyone can convert their past life memories into power in this life. He initially thought transmigrators didn't have past lives, that he was just an ordinary person in his previous existence, but suddenly he gains the powers from the anime he used to watch. First life: Kirito... How could I, Kirito-sama, possibly do gua sha? Second life: ... Third life: ...

[Naruto + Multiverse] A pair of Sharingan eyes mutated by the soul of a transmigrator will eventually reflect the Love Clan standing tall across countless worlds. "Just wait until I pull out my Spark Lens, then you'll know you've regretted it!" "War God Susanoo - WarGreymon!"

[2019 Newcomer King] The otaku beauty Hoshino Chiyuki, carrying her FGO Heroic Spirit deck, transmigrates to the world of Yu-Gi-Oh!. "Blue-Eyes White Dragon is invincible!" "Activate the effect of Grand Hero!" "Stella!" "My most loyal servant, the Dark Magician!" "Activate the effect of Grand Hero!" "Stella!!" "I..." "Activate the effect of Grand Hero!" "Stella!!!" Amidst ruins and endless corpses (referring to Grand Hero), Chiyuki wipes her forehead and smiles brightly: "[Slacking off, Yui]"

A proficiency certificate that lasts forever! A system that allows me to traverse countless worlds! I lack nothing now! In Dr. Stone, the Sword God of Ten Mile Slope, the Wilderness Gourmet, I took my first extraordinary step to save a lost civilization. In One-Punch Man, he extended an invitation to unemployed office workers: "Want to become a savior hero?" In the Biohazard world, a man and a panda roam the apocalypse: "Dragon Warrior? Savior Hero!" In Ling Cage, Battle Through the Heavens, and Mortal's Journey... step by step, he has come a long way, and in countless worlds, everyone praises him as the supreme and holy savior. But only Lin Hao knows that all of this is due to his own hard work and sweat! System! Proficiency! Give me 1000% support!

Good news, I was killed by a train at home.

Even better news: he's become the navigator of the train.

Even better news is that you can travel to the world of anime by train.

What pioneering and interesting things did you do after becoming a navigator?

She was paired with Kirito.

Adopting Lolis from All Over the World

Discussing the relationship between monarch and subjects with a famous queen

The birth of the king was celebrated with a cannon salute; God was lured onto a train; and Shiori almost fell in love with him.

Do these count?

Worlds experienced: Sword Art Online, Black Bullet, Akame ga Kill!, Date A Live, High School DxD, Guilty Crown, Academy Battle, Accel World...
