Abnormal phenomena suddenly broke out around the world, including high temperatures, heavy rains and floods, and frequent earthquakes. The former prosperous order instantly collapsed. No one knew that this devastating natural disaster was not an accident, but was closely connected to a fictional history that was deliberately erased. Chen Yan managed to survive the early stages of the disaster, but unexpectedly discovered a mutilated manuscript left by his ancestors at home. The strange symbols recorded on it were surprisingly consistent with the anomalies in the natural disaster. As the survival crisis intensifies, more bizarre disasters occur in various places: moving fog, mutated creatures, and ruins appearing out of thin air. The clues in the manuscript lead him on the road to find the truth. On the way, he encountered the pursuit of a mysterious organization and met survivors who also had sporadic clues. They gradually discovered that this natural disaster was a harbinger of historical reincarnation, and that behind the dusty secrets lay the key to human survival. Every time the disaster escalates, new clues emerge, which also brings danger closer. As the pieces of the truth gradually pieced together, Chen Yan realized that they not only had to fight against cruel natural disasters, but also faced dark conspiracies from deep in history, and the hope of survival was hidden in those forgotten codes.
