In 2083, acid rain in the Rust Belt cannot wash away the secrets of sixty years ago.
The life of Chen Mo, a restorer of historical images, was torn apart by a metal box that appeared out of thin air - the blue light patterns in the box would flow, and those who touched it could see maintenance workers walking vertically across the wall, receive a warning "Don't trust the restorers", and read the erased pre-war truth.
The rent is about to go up, a colleague is a traitor, the landlord who brings old tea is hiding a Morse code, and the man in black trench coat leaves a 72-hour countdown. Only then did Chen Mo realize that his gift of "understanding data" was the blood of the box keepers, and the "seed" in the box contained the original war sin that the Federation had covered up with sixty years of lies.
When the old port lighthouse lit up, the mecha wreckage resonated, and the truth emerging in the sky made the world tremble. He clutched the box tightly, behind him were the chasing "purgers", and in front of him was the shadow of alien visitors - some seeds must sprout after seeing the light, even if the cost is to become a sacrifice to civilization.
This is a pursuit to repair the tampered history and protect the original appearance of civilization. All the weirdness that goes against common sense is the rusty echo of the truth in time.
