The Qinling Ao Tai Line, the hiking route with the highest mortality rate, is also the ∞-shaped tomb passage that locks the giant Ao. The live broadcast team enters the mountain, the GPS collectively fails, and the shadow team kills you 5 seconds in advance; the negative audience swipes the screen, and the death prophecy is accurate to the minute. Blue-scaled heartbeat, life-saving nail, blank-faced sister, reality and the cemetery are misaligned and folded. What you thought was your escape is actually just being released back to the human world as a key - the door to the human world has been quietly reopened beneath the Xi'an Bell Tower.
