Tian Ci is the author's Chinese name, with Tian Ci as the English form. Publicly available information about his nationality and dates of birth and death is limited. What can be confirmed at present is that two works appear under his name: Invincible Battle Soul and Yin Tianzi (The Yin Son of Heaven). Judging from the categories used in the library, his writing mainly falls into male-oriented fiction, Eastern fantasy, premium fiction, and folkloric supernatural tales, covering both passionate cultivation and strange legends. Among the existing works, Invincible Battle Soul leans toward the growth-and-combat narrative of Eastern fantasy, while Yin Tianzi is closer to the imaginative space of folkloric supernatural tales, suggesting that the author tries different branches within fantasy fiction. As no fuller author statement or interview is available, details of his creative career and style cannot yet be expanded; readers may begin with these two works to sense the shifts in his writing between fantasy and the supernatural.
