One Piece: I Awakened Conqueror's Haki from the Start, and I Stop Violence with Violence

[No System] [Three Colors of Top-Tier Haki] [Martial Arts] [Greatest Swordsman] [Moderate Slow Burn] [Decisive and Ruthless] [Invincible Growth]

After transmigrating to the world of pirates and witnessing the pirates murder the older sister who loved him, could you still believe they were a group of people pursuing freedom? Would you still look up to them?

Pirates run rampant and thugs wreak havoc, while civilians are killed at will. This can only be blamed on the weakness of this world's law enforcers. Zhou Lin decides to join the Marines and personally go on a killing spree, killing until they tremble with fear, killing until they hold him in awe, and killing his way to a just and peaceful world.
