Blue Star

Biodata

History

Fifteen thousand years before the present era, the Yanhuang Empire unified Blue Star and developed into a technologically advanced civilization that explored space. Its conflict with the Interstellar Beast Race lasted 3,000 years; humanity later adopted cultivation after obtaining the Natural Breathing Method through a distress signal sent to another universe. Although humanity eventually defeated the beasts, the Yanhuang civilization was later destroyed by another civilization. 209

Blue Star has repeatedly experienced World Echoes, phenomena associated with the appearance of beings from other universes. During the second World Echo, military forces fought monsters that had never previously existed on the planet. Li Ziyu later concludes that each World Echo may be an invasion by a different civilization. 80 209

The planet remained outside the interstellar community until Azuka's adventuring group arrived. He identified Blue Star as a Level 1 civilization and stated that reporting its coordinates to the Black Dragon Mountain Empire would bring the planet under the empire's notice. 536 537
