The Decapitator System:1200 Year Old Covenant

Kin's hands are bound. His katana is twenty feet away. The firing squad of 1500 strong armed men have already raised their weapons. Then the System speaks. [Escape route calculated. Condition: Take the president's head now, a clean cut. Time window: 4.7-12  seconds .] Kin laughs. He has no weapon. No speed. No miracle, the system seems to have forsaken him with its sudden unrealistic demands . But the System didn't say he could choose  to do it. It said take…  Kin was a drunk with a death wish and a talent for bad decisions. Then a 1,200-year-old System chose him. Now he's the Decapitator—an unwilling assassin forced to execute the world's most corrupt leaders, one head at a time. Fail a mission? He feels every victim's pain. Succeed? He gets strength, money, and a harem that's more trouble than it's worth. But the real cost isn't blood—it's bonds. His landlady Lina is getting too close. The Quiet Commission is closing in. And his next target is the most guarded man alive. When Kin kneels before 1,500 soldiers with a bullet waiting for his skull, the System offers him one way out: take the president's head in the next few seconds, or die. No weapons. No backup. No mercy. But the System never said he had to play fair. Welcome to the Covenant. The headsman's work never ends—and neither does hope.
