[Prominent family background + empress + single female protagonist + enemy]

Jiang Chuan traveled to a fantasy world of cultivating immortals and found himself the eldest senior brother of a holy land, or the son of a wealthy family?

After awakening the contract's ten thousand times return system, Jiang Chuan bound himself to the reborn empress Luo Yuwei.

From then on, his invincible journey began.

"The contract object Luo Yuwei took the black gold iron grass, which increased the power of an elephant and returned the host's power of ten thousand times!"

"The contract object Luo Yuwei has been promoted to a small realm, and the host's realm has been returned ten thousand times, breaking through the peak of the Dragon Transformation Realm!"

"The contract object, Luo Yuwei, has entered the stage of practicing the Zhanshi Jue, and I will return you ten thousand times the reward for the Zhanshi Jue Great Perfection!"

...

"The contract object Luo Yuwei obtains the Holy Weapon, and I will return one Imperial Weapon to the host ten thousand times!"

Luo Yuwei: Why can’t I catch up with Jiang Chuan no matter how hard I try? Am I really going to be suppressed by him forever?

Using the Impure World Reincarnation technique, he was unexpectedly reincarnated into the world of One Piece, becoming the son of Dragon and given the name Luffy. Although the name is the same, his core has changed, and thus his path is different. He initially intended to skip the Devil Fruit and join the Navy, but after unexpectedly encountering the red-and-white-haired princess, he discovered how unfamiliar the world was. How can this be a movie world? How could my King Luffy possibly have a childhood friend and a romantic comedy?
