A strange space collapse sweeps across the city, once every seven days, leaving corpses everywhere. Lin Xun, a former mystery novelist, is the only "memory awakener". After each reincarnation, only he can retain the key memory of death.
After waking up at the starting point of seven days, he discovered that he had a power called "memory anchor point" - he could read the fragments of past reincarnations and foresee the trajectory of collapse. In order to survive, he must cooperate with the mysterious girl "Mist" and the survivor alliance, follow the cruel rules in the seven-layer space that is gradually collapsing, and find the "anchor" to escape.
However, there are undercurrents surging within the alliance, and leader Tieshan's iron-blooded methods are chilling. The hunt by the guardians follows them everywhere, and the truth of the space is far more terrifying than imagined. Is this an AI-simulated purgatory or the final projection of human consciousness?
"Memory is not a burden, it is the only weapon." Lin Xun must use the information obtained from each death to uncover the ultimate secret of the City of the End. This is a race against time, rules and human nature. Is the end point, destruction or rebirth?
