Kan Ki, originally named Huan Yi, rose from leading the largest bandit gang in southern Qin to join the Qin military. Discovered near death at age thirteen by the Saki Clan, a band of marginalized youths, he forged them into a powerful bandit force. Societal oppression, culminating in the brutal torture and death of his lover Shio by a local lord, seared a nihilistic worldview and rage against injustice into him. This drove him to slaughter the lord's entire household, earning the epithet "The Beheader." Recruited by Qin general Mou Gou, Kan Ki ascended rapidly through the ranks via unconventional tactics and strategic brilliance. Serving as a vice general in the Mou Gou Army, he demonstrated unexpected loyalty to Mou Gou despite his mercenary nature. After Mou Gou's death, Kan Ki attained the rank of Great General, becoming the fifth of Qin's new generation of Six Great Generals. His warfare relied on psychological terror, deception, and extreme brutality. He routinely orchestrated massacres of surrendered soldiers and civilians, using mutilated corpses to demoralize foes, such as displaying dismembered villagers at the Battle of Heiyang to provoke an enemy commander into error. He prioritized exploiting human weakness over conventional strategy and openly relished warfare's cruelty. Kan Ki maintained complex bonds within his inner circle, treating commanders like Raido, Koku'Ou, and Ma Ron as family while remaining indifferent to the wider Qin army. His nihilism extended to Qin itself; he dismissed kingdoms as "cesspools" enabling elite oppression and professed indifference to Qin's potential fall during the Coalition Invasion. Nevertheless, he showed rare respect for Mou Gou, saluting him formally and honoring his death by burning Wei prisoners. His final campaign occurred during Qin's invasion of northern Zhao. After executing 100,000 surrendered Zhao soldiers to avenge Raido's death—an act condemned by Qin's king—he faced Zhao strategist Ri Boku at the Battle of Hika. Outmaneuvered and besieged, Kan Ki launched a desperate assault that nearly killed Ri Boku before he perished alongside his core commanders. His last words dismissed Ri Boku and Qin's king as equally ineffective "chumps" perpetuating endless conflict.
