During a bizarre robbery on a stormy night, convenience store clerk Su Xia discovers that she can see fragments of the future. The mysterious Lu Chuan’s appearance sends her fate plunging toward an abyss: the “Doorway Hours” between three and four in the morning are tearing apart space and time, as reality and dreams begin to bleed into each other.
A glowing crest appears on her arm, three hours vanish from the security footage, and memory worms run rampant in the morgue... The shadow of the “Doorway Opening” incident from twenty years ago once again looms over the city. When Su Xia meets another version of herself in a mirror world, she finally understands that her parents’ encrypted diary contains the truth about a forbidden experiment capable of overturning the world.
A bronze pocket watch that loops time runs backward in the downpour, while quantum collapse causes veins to sprout from the convenience store shelves. On a dream battlefield built from silver sand, the awakened master of time must face a blood-red dawn: closing every doorway will erase Lu Chuan from existence, while letting the worlds overlap means watching the irises of seven billion people become crawling with silver parasites.
This is a high-stakes gamble over memory and lies. As a black crystal altar materializes in the real world, an ultimate choice emerges at the end of Su Xia’s precognitive dream: is tearing away the gentle illusion worth the price of exchanging it for the heartbeat of someone she loves?
