Core of worldview
The two realms of Yin and Yang: The human world and the underworld are connected through the "Yellow Spring Node", and Mr. Yin and Yang is responsible for maintaining the balance.
Power system: Apprentice → Taoist Disciple → Taoist Master → Celestial Master → Great Celestial Master (each stage is divided into nine levels)
Ghost level: wandering ghost → ghost → ghost general → ghost king → ghost emperor
Core conflict: The "book of life and death" in the underworld has been tampered with by mysterious forces, causing the trapped souls and the collapse of reincarnation.
