Time Travel + Pirates + Unlimited Devil Fruit + Fusion + New Plot

In the flames of the laboratory explosion, chemistry master Luo Yu was swept into a vast blue ocean - this is the world of One Piece!

When he discovered that he could "preemptively seize" all the Devil Fruits, instantly reducing the original owners' abilities to zero, a sneer curled up his lips: Crocodile's Sand-Sand Fruit? Blackbeard's Dark-Dark Fruit? The Empress's Sweet-Sweet Fruit? Sorry, I'll have it first!

The fist wind of the martial arts master is wrapped in the natural elements, and modern wisdom collides with the madness of the pirate world. From the moment Nami was rescued from the East China Sea fishing village, Luo Yu's sails were destined to set off a storm.

Modern chemical knowledge analyzes the structure of the fruit, and martial arts strength enhances the power of fusion. From saving Nami and forming a team, to Robin crying for him, to the Empress taking the initiative to join the team, every step Luo Yu's ship takes is rewriting the rules of the pirate world.

This time, there is no "original plot", only Luo Yu's "Infinite Fruit Era"!

Official Introduction: Now approaching you is: Muzan's nightmare, the destroyer of the Twelve Demon Moons, the head of the Infinity Castle demolition office, the most righteous person in the Demon Slayer Corps, Sabito's savior, the eternal absentee of Kanae Kocho's tea party, Giyu's good senior brother, the founder of Fist Breathing, and a grandmaster.

Shinobu Kocho: "Why should I be trained by iron fists? It's infuriating, sister!"

Akaza: "A powerful person, the best in physical combat."

Muzan Kibutsuji: "A monster who destroyed all my Demon Moons with his bare hands and blasted the Infinity Castle to pieces, you call him human?!"

Unofficial synopsis: Yagyu In transmigrates to the world of Demon Slayer, but the system believes he is in the world of One Piece and identifies him as a Marine.

You can earn Navy Points and rewards by doing things that are in line with the Navy's rules.

Yagyu In: No, buddy, is this right? Where did this pirate from the Demon Slayer world come from that I need to catch?!

Pirates are attacking! Strike immediately to capture or kill them!

Looking at the man-eating ghost before him, Liu Shengyin realized that the system had gone mad.

From then on, the Demon Slayer Corps had one more instructor who liked to smash people's heads with his iron fist of love.

This book is also known as "Left Fist's Overpowering Entanglement Deals High Damage, Right Fist's Overpowering Entanglement Deals High Damage," "Three Punches Shatter Evil Spirits, Sir, I'm Just an Ordinary Person," "Overpowering Aura is Also Qi, and Qi is Breathing Technique!" and "Muzan, Are You Hiding Well?
