Pseudo-Era

Three hundred years ago, the Divine Relics came to earth.​ The old civilization collapsed, and humans retreated to the five-layered ring city, fighting with the alien races outside the wall to this day.​ Over the past three hundred years, everything seems to have been answered.​ It wasn't until the day when 19-year-old Cheng Chuan enlisted in the army that his comrades who had trained with him for three months were found to be non-human.​ One thing that should have ended here has led to more and more things that shouldn't exist.​ And in the depths of the unreached wilderness, those beings that had been sleeping since the old era began to make movements.​ Many years later, Cheng Chuan looked back and realized that everything seemed to have started on that day.​ An ordinary enlistment inspection.​ A dead recruit.​ And a question that no one has seriously doubted in the past three hundred years——​ Was that really what happened back then?
