Considering the powerful "transformation" ability of the Sinking Sand Giant Worm on the terrain and topography, Sun Hang ultimately chose to stay put—ghost subway is clearly a rule-based supernatural entity, and the best way for rule-based entities to "operate normally" is to ensure that all triggering "conditions" remain unchanged.
No one can guarantee that after the Sinking Sand Giant Worm turns the dunes upside down, the subway card Sun Hang holds can still summon the ghost train.
Sun Hang stayed honestly until local time 23:23, then swiped the Chunming City subway card at the self-made subway turnstile again.
Accompanied by a slight tremor in the dunes, the ghost train emerged from the flowing sand and stopped in front of Sun Hang.
"What's good about rule-based supernatural entities," Sun Hang stepped into the compartment, as if talking to himself, or to the main brain, "is that they follow rules and reason. I like such entities."
