Here the three rooms and six realms are the nine realms
The three realms are the great realm. The middle and lower three realms are equally famous in the world. They are the heaven, the human world and the capital of the underworld.
The six realms are relatively mixed, and they are all dependent on the three major realms.
For example, monsters and sharks all exist in the human world and coexist with the human race. They have their own territory and cannot be invaded. The human race does not like these foreign and uncontrollable species. It is the common point of the human race to annihilate them on sight.
The spirit bird tribe belongs to gods and is attached to the heaven. Most of them are the mounts of the priests.
The ghosts and demons remain in the underworld, and they can be much more at ease with the three tribes above.
The only remaining realm is the Parallel Mirror. It is said that this realm means that anyone who enters the mirror can achieve their wish.
Intention: Waiting and rebirth
