When the star trail light belt over the city suddenly shed blood, the children in the kindergarten sang strange nursery rhymes, and the crystal ball in the resonance room that had been dusty for thirty years came to life - Jing Run clutched Su Tang's pen and finally understood the words in his predecessor's diary: "The star trail is not just a machine, it is a container that holds the thoughts of millions of people."
An ordinary star track maintainer, a pet shop owner who can understand animal language, a photographer who is obsessed with star maps, and a kindergarten teacher who guards a dandelion field are all involved in the vortex because of an "emotional resonance" that spans generations. They dug out star crystal fragments in the cellar of the old locust tree and cracked the emotional code in the hum of the singer. Only then did they discover that the truth of the star track is far gentler than imagined - it is a cosmic "emotional lighthouse", and human emotions are the light that illuminates the darkness.
From the alarm of the bloody light belt to the out-of-control harvesting plan of the main system; from the dim light of the resonance room to the emotional firewall of seventeen nodes, they used laughter to neutralize sadness, and used regret to nourish courage. In the pull of "perfection" and "incompleteness", they understood: the so-called protection is never against the darkness, but to allow every emotion to have a place to live.
When the dandelion seeds fly into the universe on the rainbow light belt, the light belt of the star track always flows with this story: a group of ordinary people, with all their imperfections, live seriously, love and regret, making the earth the warmest "emotional island" in the galaxy.
