Biography

The ore-gathering apprenticeship fraud

He teaches Song Zhen and dozens of others a cultivation method suited to detecting earth flames but incompatible with forging, then blames their supposed lack of talent. Zhang Xuan reconstructs the scheme, confronts Sun Jin before the guild, and proves that the instruction—not the apprentices—caused their failures, destroying the reputation that protected the exploitation. (Chapters 1,021–1,025)

Appearance and personality

Sun Jin is calculating, hypocritical, and willing to weaponize the title of teacher for free labor. (Chapters 1,021–1,025)

Abilities and cultivation

His six-star pinnacle forging and guild connections give him real professional standing. They cannot conceal a cultivation method's structural conflict from Zhang Xuan's analysis. (Chapters 1,021–1,025)

Relationships
