Chen Mo, a medical student who "went ashore" after graduation, was hit hard by the cruel reality of medical reform before he could even put on his brand new white coat. During the day, he is a tired "cow horse" on the ground floor of the hospital, and at night, he transforms into a delivery rider who shuttles through the rain, just to get a breather in the cold cracks of the city. A rainy night when he broke into the abandoned community "Jinhuayuan" in a hurry, completely tore apart the reality he was trying to maintain. Deep in the ruins, there was a strange lilac light, like the gaze of the abyss, which instantly swallowed up his consciousness. When he woke up from the cold mud, there was an inescapable purple bracelet on his left wrist - it was as cold as ice, but had a weak pulse like a pulse.
> What was even more horrifying was that Chen Mo was horrified to discover that the beating rhythm of this bracelet was surprisingly synchronized with the heartbeat of the dying patient in his emergency room.
