Background / History

Xu Yi was transported to Puxi City shortly after graduating from university. Carrying a letter of recommendation, he traveled from the town of Under the Sky Lantern and became Mister Ye Hai's disciple at Golden Orchid Nunnery, the Puxi branch of the Green Gang's Jiahai Hall. During his first half-month in the city, he learned basic martial practice and jianghu principles from Ye Hai. 2

His first assignment was to collect protection money from Hongfa Fruit Firm. Rather than simply extorting the shop, Xu Yi established the firm as his territory and arranged its protection, earning Ye Hai's approval and a continuing share of its monthly payments. 2 4

Appearance

Xu Yi commonly wears the black traditional jacket and black gang uniform associated with Ye Hai's men. He later carries firearms beneath a loose Tang suit while working around Lingtong Hall. 2 32 35

  • Black traditional jacket, with silver dollars kept in an inner pocket. 2
  • Uses Ye Miao's sachet at his lapel or in hand to activate spiritual perception. 20 35
  • Carries concealed pistols and ammunition while conducting dangerous investigations. 35

Personality

Xu Yi is reckless enough to use his own life as leverage, but his recklessness is tied to a strong instinct to protect others. He resists harming innocents even during planned killings, pulls back when an enemy uses a child as a shield, and intervenes on behalf of Jing Tao despite refusing the security that marriage into her family would provide. 2 15 20

He initially takes Ye Hai's teachings on benevolence and righteousness seriously, but experience steadily makes him more suspicious of jianghu rhetoric and manipulation. He recognizes Ye Hai's effort to place loyal agents inside Lingtong Hall and refuses to act blindly on his master's proposal. 15 33 50

Xu Yi is intensely curious about spirituality and fragrance, yet he can exercise restraint when he recognizes a danger. He refuses the old man's spiritually charged cigarette, avoids prolonged conversation with Ji Xiao after learning her control condition, and resolves not to become the incense-obsessed version of himself shown by the burner. 19 21 25
