A Fusion of Devil Fruit Powers? I'll Crush the Old Era!

Transmigrating into the old era? You’ll die! What? I can replicate and combine Devil Fruit abilities? What? Rumble-Rumble Fruit + Magnet-Magnet Fruit = Logia-type Electromagnetic Fruit? Haki is powerful, sure, but what if I told you I could combine them into a Black Hole Fruit?

Well, then, no problem! Let’s settle it in the Grand Line. Who’s afraid of whom?!

Kaido unleashed a Thunder Bagua and had just declared that Haki reigned supreme over all, but when he saw Lu Xing casually conjure a “black hole,” his neck jerked back and he hurriedly explained that everything he’d said was drunken nonsense!

Kizaru: “Young man, have you ever been kicked at the speed of light?” A moment later, he raised both hands and pursed his lips. “Kawaii ne~ When did you steal my power?”

Garp breathed on his fist. “Kid! Don’t you dare run!”

Lu Xing suddenly turned around, holding a “black hole” in his hands.

Garp: “Kid, don’t you dare chase me!”
