In the "Xingang City" of the near future, memories are no longer illusory brain waves, but physical crystals that can be extracted, stored, and even traded. The protagonist Chen Mo runs an underground pawn shop called "Wangyou Pavilion", which specializes in acquiring painful memories that people want to abandon. However, when he received a black crystal with the military's highest encryption level, he discovered that what was hidden inside was not someone's pain, but a countdown to a disaster that was about to wipe out the entire city.
Intention: Countdown to disaster that is about to wipe out the entire city.
