Three thousand years ago, the continent was shrouded in a sudden black fog, causing diseases to breed. "Evil spirits" stretched out their claws and spread to the entire world. In just six months, all life was devastated. Eighteen lighthouses were born, followed by an intelligent "system". The black fog dissipated, the evil spirits were suppressed, and the continent was able to breathe. The "system" tells all living beings that lighting the lighthouse can temporarily drive away "outsiders", and all living beings have the opportunity to gain power and win a bargaining chip for their own survival. From then on, the mainland ushered in a new era: the era of symbiosis between the apocalypse and law.
But in the end, what you rely on for survival is the culprit of suffering.
