Dragon Scale Stranger

Introduction to the work On the day when the sky was covered by an unknown magnetic field, satellites failed, communications were interrupted, dragons roared through the sky, and traces of hunting and dismantling were left in the gaps in the ground world. A graduate student at the Institute of Science and Technology. During a field survey, he detected a waveform that should not exist, and followed the signal and met an alien race numbered "533". She wanders around the edges of human cities, without explanation or alliance, only collecting fragments on the road. Graduate students did not report. He kept some of the data and shared the same map with her. The end point of the fragments pointed to a cracked door. The thing inside the door had noticed them.
