[Pirate faction] [Slow burn] [Gradual growth] [User of the Nen-Nen Fruit] [Great swordsman] [Powerful user of all three types of Haki] [The Float-Float Fruit is fake] [No female lead]

Hey hey hey~~

Golden Lion: Roy, why isn't my Float-Float Fruit as strong as your Mind-Mind Fruit?

Roy: How should I know?!

Barrett, Mihawk, Tezzo, Crocodile...

Hurry up and get on the ship.

Roy arrives in the world of One Piece and discovers that the future powerhouses are still young.

They lured them all onto their own boat, one by one.

When Luffy set sail, Roy looked back and exclaimed, "Oh no! I've become the world's ruler!"

When Luffy arrived in the New World, Roy looked back at his team and said, "Brothers, you guys go first. I'll see what this guy is all about."

"Awakened the incredibly powerful genjutsu Kotoamatsukami, and then just died like that? Uchiha Shisui, do you even know how to play games?" "They just decided to rebel, and then they surrendered after seeing their son slaughter the entire clan. Uchiha Fugaku, are you kidding me, clan leader?!" "And Uchiha Itachi, your son... well, mentally ill people can kill without consequence. You're mentally ill, so what!" Having transmigrated into the Uchiha clan, right after the Nine-Tails' attack, Uchiha Shuichi felt a bit overwhelmed. He searched for his cheat ability for ages, only to be told it couldn't be used for ten years. But he did the math: at most seven years, and the Uchiha clan would be wiped out. "Whatever, the Third Hokage could fool Uchiha Shisui and Uchiha Itachi, I can still play the role of the Fire Intent..."

Yu Qing transmigrated to the Douluo Continent. The bad news was that his awakened twin martial souls were the standard useless ones, Green Leaf and Iron Block, and his innate soul power was only level three. The good news was that he possessed eyes that could see destiny, allowing him to find corresponding opportunities based on the color of that destiny. Relying on his precognitive abilities regarding the Douluo Continent, Yu Qing embarked on a path of reversal. Leaving a small coastal town, he sought opportunities, endured countless dangers, traveled the continent, and transformed his martial soul. He created his own cultivation technique, the Star Meditation Scripture: feeding on the power of stars to strengthen his physique, open his meridians, and increase his soul power, allowing his cultivation to advance by leaps and bounds. He also created his own body-refining method, the Thousand Hammers Refinement Method, using soul power to temper his body and absorb soul rings beyond his limits. He further created the secret technique, the Burning Star Battle Technique, granting him the ability to fight beyond his level as a support-type soul master. Finally, after twenty years of arduous cultivation, Yu Qing reached...

Our family has fallen on hard times.

The once glorious Uchiha clan has been reduced to its last remaining descendant, you.

[Side Quest 1: Enhance your strength and uncover the truth behind the family's decline.]

[Second Side Mission: Spread Your Fame Far and Wide, Do Something Great and Shake Up the Ninja World.]

[Side Mission Three: Propagation and Restoration of the Uchiha's Glory - It is Our Inescapable Duty.]

Looking at the system in front of him, Tiandao wanted to shout, "Damn idiot! System, do you even recognize me as an Uchiha?"

However, looking at the rewards listed by the system: [Sharingan, Hashirama Cells, Sage Mode, Yin-Yang Release.]

"Since that's the case, then let me see your limits. System, activate it!"

Tiandao, born a commoner, is a mere transmigrator. Watch as he stirs up the ninja world with the help of a mentally challenged system.

【Honghuang】【No system】

After his death, Ling Tian traveled through time to the ancient times and became an innate treasure, the twenty-fourth-grade Green Lotus of Creation. He cut off his own origin and transformed into a human form.

He transformed himself to search for spiritual treasures to restore his own essence, then quietly hid away to practice and plan the great war between Taoism and demons. He quietly achieved the Dao of Hunyuan.

He was well aware of the plans of Honghuang Tiandao and Hongjun, and planned the witch-lich calamity, helped Houtu evolve the six reincarnations, and gave magical treasures to Nuwa to help her behead corpses, so that the earth and humanity could awaken. Tiandao and Hongjun could only be helpless and furious.

The prehistoric world finally became complete under Ling Tian's layout. Ling Tian became a behind-the-scenes person and quietly hid the boss.

Qin Feng is reborn in another world.

The intelligent brain descended, and the [World Dimension] appeared.

Popular novels in real life can be used to develop martial arts techniques!

Country M has the Marvel system, while Country R has systems such as the Beads system.

But my great nation of China has only a garbage system.

Qin Feng was overjoyed when he discovered the gap in the novel.

Gu Long and Jin Yong created a completely new martial arts system.

There are even more advanced martial arts, fantasy, and other genres waiting for him to create.

Qin Feng declares: China is rising!
