The story takes place in a "new era" (Era of Star Calendar) where technology is extremely advanced. Human beings have footprints all over the solar system. Gene editing, neural access, artificial intelligence, and space colonization have become the norm. At the same time, the relics and legends of ancient immortal civilizations are regarded as a kind of "super-ancient technology" or "extraterrestrial civilization heritage" that has not been fully confirmed.
Very beautiful and exciting
