The world is shrouded in the shadow of the disaster a hundred years ago. This terrifying existence originating from the unknown abyss riots with the lunar eclipse, forcing humans into shelters like steel fortresses. They are growing like toadstools on the surface of the earth; the southern hemisphere has long been reduced to a desperate situation. The last edge of mankind is the elite armed force that walks on the edge of the blade - "tailor". They used flesh and blood as threads to mend the broken edges of civilization.
A hundred years later, a young man named Cheng Qianyu was torn apart by double nightmares. Zheng was imprisoned in a claustrophobic space night after night, listening to the ringing of bells, and his spirit was on the verge of collapse. He struggled with the frozen gap between father and son, the suffocation of moldy alleys, and the endless bullying in the corners of the campus. He was pale and frail, like a candle in the wind.
If one day there is a scarlet lunar eclipse, the tragedy of a hundred years ago will happen again, and the gears of fate will begin to mesh. The "dong dong" sound buried deep in the young man's soul is about to have a fatal resonance with the cold laws of this world etched by disaster.
