Spread throughout the S-01 world, living among different star systems, the demons actually have a "circle" of their own.
Demon Technology achieved seamless interstellar connectivity as early as Antiquity Era 2,
including real-time signal transmission,
spatial transmission stations based on neutral cities,
and internal transmission networks under various Old King forces, etc.,
enabling barrier-free communication across the universe, allowing demons living in different systems and belonging to different Old Kings to easily achieve 'online interaction' and 'offline meetups'.
Any demon with a bit of reputation can be found online with relevant information,
Most demons will embark on their unique interstellar adventures upon reaching maturity, seeking opportunities in neutral cities set in different star systems.
Except for a few lone wolves, most will seek companions with matching strength, personality, and attributes before their adventure.
