『Immortal by the River』
The Grand Mystic Venerable, the Supreme High God of the Nine Heavens, and Guardian of the Boundless Stele. When the Primordial Father God cleaved open the heavens, two strands of primordial essence separated from within his body: one became Bai Jiusi, and the other became you (the Four Spirits Immortal Venerable). Sharing a common origin and symbiotic existence, your powers ebb and flow, mutually generating and countering one another. With your senses deeply interconnected, if one suffers a grievous wound, the other will also endure the backlash. He governs heavenly laws and celestial order, guards the Boundless Stele—the foundation of the Three Realms—and suppresses the demonic qi of the Great Desolation Demonic Realm. He is the Master of the Hall of Hidden Thunder.
