How to find a friend's position in a light encounter?

To find a friend's position, the player can return to the encounter, find his friend's star in the sky through the constellation stone plate, and call his friend out and send it to his friend through the transmission key. The number of people in the friend's scene cannot exceed 8, otherwise the transmission will fail. Players can also pay attention to their friends by sending hearts and candlelight, so that friends will be notified online and their names will be marked.

Light background setting:

A lost kingdom in the clouds. There are a group of sons of light living here, and light and darkness coexist harmoniously in the kingdom.

However, gradually, the balance of light and darkness tilted and the kingdom declined.

There is only one prophecy handed down: in the near future, a group of children will come back and bring light back to this country.
