## One Piece Chapter 681, pages 7-9: Luffy vs Master - Chapter: 681 - Pages: 7-9 - Characters: Monkey D. Luffy, Caesar Clown ### Summary Page 7: Luffy measures the danger while panting: "HAA... HAA... SO IT'S ABOUT THIS DISTANCE, HUH!!" Caesar confirms it with cruel confidence: "SHURORORO... THE SPACE WHERE YOU CAN'T BREATHE IS INDEED WITHIN A FIXED RANGE!!" Luffy asks the real question: "BUT CAN YOU KEEP THAT DISTANCE?" and begins his counterattack. "GOMU GOMU NO--" he calls, stretching his arm through the safe gap, then drives forward with "JET PISTOL!!" The blow slams into Caesar with a heavy impact, making him grunt, "UGH!!" Luffy has found the edge of Caesar's suffocation zone and uses his rubber reach to attack from outside it. Page 8: Caesar is knocked away and cries, "AHHHH THAT HURT! SHIT! SHURORORORORO!!!" Luffy skids after him with "DRIFT," keeping his momentum. Caesar, still confident in his science, says, "SEE, YOU'LL SUFFOCATE IF YOU GET CLOSE!!" Luffy forces himself forward anyway and mutters, "UU!! NOT AGAIN..." Caesar opens a new attack and says, "BEHOLD, THIS IS OXYGEN!" Luffy, startled, asks, "IT HURTS, DOESN'T IT?" Caesar grins: "I'VE STILL GOT PLENTY OF WAYS TO ATTACK SOMEONE UNAFFECTED BY POISON GAS, LIKE YOU!!" He forms a glowing blade and shouts, "'BLUE SWORD'!!" The note explains that the kanji read as "blue flame sword." Caesar has weaponized pure oxygen flame, changing from suffocation to cutting heat. Page 9: Caesar swings the blue flame blade at Luffy and declares, "NOW, BE CUT BY MY FLAME!!" The slash carves across the room with a sharp "SLASH," tearing through smoke and debris while Luffy dodges back. Caesar presses with more flame and laughs, "SHURORORORO...!!" but Luffy refuses to give him room. As Caesar prepares to harden himself, the phrase "ARMAMENT HARDENING!" appears, and Luffy gasps at the movement. Caesar's gas body and flame blade are now paired with Haki defense. The scientist is not merely hiding behind poison; he can fight in several layers at once, switching between gas, flame, and hardened body.
