1. **Visual and atmospheric contrast of urban immortality:** The ancient antique shop vs. The modern urban rainy night outside the window; Ye Chen's Tang costume and method of cultivating immortality (repairing the ancient tripod) vs. Xiao Ning's modern attire, police identity, and gun.
2. **The core conflict is revealed:** Xiao Ning insists on legal procedures and principles of justice, while Ye Chen implicitly points out that the incident involves supernatural forces, implying that mortal legal and investigative methods are ineffective and even dangerous. The fundamental differences between the two people's positions and worldviews collided head-on for the first time.
3. **Display of character traits:**
* **Ye Chen:** Out of the world, indifferent, guarded, strong and reserved, disdainful of secular rules, worried about getting involved with mortals (although expressed in a cold way). It is reflected through actions (fingertip aura, changes in momentum), language (conciseness, alienation, warning) and environment (controlling the atmosphere in the store).
* **Xiao Ning:** Capable, sharp, persistent, with a strong sense of justice, not afraid of pressure, and intuitive to abnormal phenomena. It is reflected through actions (pressing the gun, glancing with eyes), language (frank questioning, declaring determination) and inner activities (feeling of Ye Chen's aura, intuition of the mystery).
4. **Suspense foreshadowing:**
* What are "things you shouldn't touch"? (Celadon bottle? Other spiritual objects?)
* What was the cause of Chen Bo's death? (What did the evil cultivator do? The backlash of spiritual things? Is it related to Ye Chen's warning?)
* Does Ye Chen's "trouble" refer to Xiao Ning's investigation, or does it refer to
