Holy City in Another World

At the beginning of the story, I don't know when or where, a crushing invasion war led to the destruction of a holy dynasty, but will this holy dynasty become history? No, it won't, it will write its chapter thousands of years later. I was awakened from the haze with a soft whisper. I didn't know where I was, where I came from, and I didn't even know anything about myself or the surroundings except my name. What was surprising was that there seemed to be a group of people like me around me. In this strange and strange state, where should I go... The ruins of buildings were scattered in the sky outside. This was obviously not a normal situation. The people in the small town almost turned a blind eye to this abnormality, as if they were used to it... After that, in order to complete the thirty-day mission, I had to put myself in danger and struggle in this strange place... This novel and its characters are purely fictitious.
