So Sui, recognized in Qin as Chu Sui, rises through the ranks as a stalwart military commander, shifting from second-in-command of the Kaku Bi Unit to a pivotal role in the Hi Shin Unit after his former superior’s assassination at Sanyou. His visage bears the marks of battle—a scar slicing across his left eye and cheek—complemented by long black hair, a trimmed goatee, and the distinctive colored cape of a Qin officer. Hailing from Qin’s heartlands, his loyalty anchors him first to Kaku Bi, then to Shin, seamlessly merging 700 veterans of the fallen Kaku Bi Unit into the Hi Shin’s ranks. A strategist forged in discipline, he spearheads decisive actions: shattering Gen Pou’s defenses at Sanyou, thwarting Zhao advances during the Coalition Invasion to secure Man Goku’s downfall, and honing the Hi Shin cavalry into a relentless spearhead. Though logistical oversight and recruitment duties later temper his frontline presence, his glaive remains lethal—evidenced by Gi Ryou’s fall and near-deflection of Gai Mou’s blows. Setbacks at Choyou and Koku You, where foes like Ba Tei overwhelmed him, contrast his ascent to 5000-Man Commander post-reforms in the Three Pillars era. Before ceding logistics to Ka Ryo Ten, his organizational prowess sustained the unit, while combat stats mirror his dual mastery: leadership and intelligence (85), assistance (90). His resolve, rooted in honoring Kaku Bi’s memory, ignites fervor in troops against adversaries like Rin Ko. Evolving from doubting Shin’s rash tactics to vowing unwavering allegiance, he emerges as the Hi Shin Unit’s tactical linchpin, steadfastly steering them through war’s crucible.
