Chong Yuan, also known as Suu Gen, serves as a key infantry commander in the Qin military's Hi Shin Unit. He trained at the Goukouken School, mastering orthodox swordsmanship and martial arts before enlisting in the Qin army at age 17. Overwhelmed by fear during his first battle, he failed to strike any opponents and wet himself during an ambush, earning the derogatory nickname "Pants Pisser." Determined to reclaim his honor, he later tracked down and severely beat the soldiers who ridiculed him, marking a turning point in his career. He stands tall with dark brown hair styled in a flat top with a topknot, viridian eyes, and brown skin. After the Battle of Bayou, where he loses his left eye, his appearance becomes distinctive due to the eyepatch he wears. He typically wears minimal armor, often only a cuirass for torso protection. A sword fanatic confident in his martial abilities, Chong Yuan demonstrates perceptiveness by recognizing Shin's combat prowess early on despite Shin's youth. His loyalty to the Hi Shin Unit remains unwavering throughout its growth from a small force into a formidable army. As one of the original squad leaders recruited during the Hi Shin Unit's formation as a 100-man special force, he participates in critical campaigns like the Battle of Bayou. There, he leads the vanguard when speed is essential to breach enemy lines and confront General Fuu Ki's elite guards. In later battles, such as the confrontation with Zhao commander Houken, he advises tactical caution against reckless charges and coordinates spear-throwing strategies to create openings for Shin. His combat experience evolves significantly across multiple conflicts. By the Zhao invasion, he attains the rank of 3000-man commander, overseeing infantry operations with precision. The loss of his eye at Bayou symbolizes his transformation from a fearful recruit into a seasoned veteran. His leadership during flanking maneuvers and defensive actions contributes directly to the Hi Shin Unit's survival in near-annihilation scenarios. Over time, he develops close bonds with fellow veterans like Shou Sa. His analytical assessments of enemy strengths during battles prove strategically valuable. His journey reflects a progression from personal redemption to becoming a respected pillar within the unit, mentoring younger soldiers through his resilience and dedication to Qin's military campaigns.
