One Piece Chapter 6, page 2-3: Chapter 6: Number One

Luffy struggles with the thick ropes binding Zoro, grunting, "UNH! THESE KNOTS ARE TOO TIGHT... I CAN'T UNTIE 'EM!" Zoro urges him on, shouting, "C'MON! HURRY UP!" Nearby, Koby slowly regains consciousness, groaning, "UNH... OOOH... WHERE AM I?" Helmeppo gasps in terror as he watches the Marines charge, crying out, "YIKES! WHAT!!?" Koby suddenly realizes the danger and screams, "LUFFY!! ZOLO!! WATCH OUT!!!" Luffy desperately tries to loosen the bindings, saying, "THERE'S NO TIME!!" before successfully freeing a portion: "THERE! I UNTIED ONE OF YOUR ARMS!" Zoro barks back, "GIVE ME MY SWORDS, MORON!!" Meanwhile, Captain Morgan roars in fury, "THOSE WHO DEFY ME MUST DIE!!" as the execution squad closes in.

With a massive, resounding "KLANG!", Zoro blocks the onslaught of the Marine execution squad. Having successfully retrieved his three swords, he holds one firmly in his mouth and one in each hand, effortlessly halting every single blade aimed at him and Luffy. The impact creates a powerful shockwave, leaving the Marines completely frozen in place.
