Chen Tianhai

Chen Tianhai is a senior Taiyan Sect cultivator whose expertise in deduction and extreme variables is inseparable from his guilt for altering the Xuanhuang Realm's ancient future.

Biography

Chapter 785

Chen Tianhai receives Xu Bai and Fang Zaiji through the Dao Deviation Stone Mother, bargaining for information from beyond the Immortal Ruins and explaining how the Taiyan Sect measures changes in the world's trajectory. In a later cycle, he permits Yi Xing's return and receives Sun Erlang as the Holy Emperor's envoy, recognizing him as an Extreme Variable and supplying a Dao Deviation Stone with the necessary secret method. The encounter revives the decisive ancient fact: Chen once activated the Stone Mother without authorization, performing vast deductions that gave the Immortal Ancestor a path to victory and helped bring down the Ten Great Sects and six Longevity Immortals. (Chapters 785–788; Chapters 1193–1198)

Appearance and personality

Chen Tianhai first manifests from blue light as a rather handsome man. He is calm, perceptive, and deliberately difficult to read, asking bluntly what visitors will trade while revealing only the knowledge useful to his purpose. His later treatment of Sun Erlang combines curiosity, caution, and lingering responsibility for the world-changing deduction he initiated. (Chapters 785–788; Chapters 1193–1198)

Abilities and cultivation

Dao Deviation Stone methods

Chen uses the Dao Deviation Stone Mother and the Dao Transformation Divine Unity secret art to model possible futures, identify focal or extreme variables, and study forces beyond ordinary calculation. The system is extraordinarily powerful but not infallible: an Extreme Variable can overturn established projections, and unauthorized deductions can produce catastrophic political consequences. The corpus does not assign Chen a dependable formal realm. (Chapters 785–788; Chapters 1195–1198)

Relationships

• Fang Zaiji recognizes Chen and participates in the first negotiation with the secluded Taiyan Sect.
• Xu Bai trades outside-world information while Chen probes the clone's unusual origin.

Items

• The Dao Deviation Stone Mother is the Taiyan Sect's central institutional treasure, not Chen Tianhai's confirmed private property.
• A Dao Deviation Stone passes to Sun Erlang together with instructions, leaving Chen's custody.
