The mysterious rules of seven-day reincarnation
The world is stuck in a state of reincarnation that completely resets every seven days. At the beginning of each reincarnation, all history and memory will be initialized, except for a few special people or things that retain some of the memories or abilities of the previous reincarnation. This reset involves all aspects of the physical world, from human social structures to the layout of the natural environment.
The reason for the reset is related to an ancient supernatural power. This power gradually awakens in a seven-day cycle, and the only way to stop it is to find the seven "keys" hidden in each reincarnation. When the seven keys are collected and activated at the same time, the reincarnation can be broken and this ancient power can be completely sealed.
Special people and organizations
Awakened: A small group of people who can retain memories in every reincarnation. They have different identities and come from different professions, regions and social classes. These awakened people spontaneously or were guided to form an organization called the "Breaking Society". Their goal is to find the seven keys and break the cycle of reincarnation.
Lawful ones: There is a mysterious force that seems to be maintaining the seven-day cycle of reincarnation and secretly preventing the actions of the awakened ones. Their identities are hidden, their abilities are high, and their methods are diverse. Some of them may even be awakened people, but they choose to stand on the side of the cycle. They call themselves "order defenders" and believe that reincarnation has its inherent meaning of balance, and that breaking it will bring greater disaster to the world.
