Jiuzhou Era Tribulation

All the border guards lost contact overnight, except for a young man named Songwazi who had a very light soul and escaped back to Tieguan City. It is said that none of the Fengsui soldiers died, but they just forgot who they were. Xuange Qingshan, the guardian of the northern border, naturally understood that this was not a demonic disaster, but that the world was forgetting him. The most terrifying thing is the transparent shadows wandering around on the new moon night. They mean no harm and simply pass quietly through city walls, houses, and living bodies. People who are penetrated by them will forget the appearance of their wife, the name of their son, and even who they are. They are called "wandering souls". They are not enemies. They are the cry of a dying world. When the world only has twenty-one years left to live, the twelve fires must prove that they are worthy of being remembered by the next era before civilization completely dissipates. But first, they must survive this tender and complete oblivion.
