[The Spirit Realm Within the Inner Spirit]
This sentence sounds awkward and strange, making it hard to understand... but that's how it is...
To put it this way, it might give the impression of a marketing slogan... What's the deal with "the Spirit Realm within the inner spirit"? Let's break it down together.
The Spirit Realm within the spiritual body actually means that the Spirit Realm is hidden within the spiritual body's inner self. You might be quite surprised, but that's how it is...
Whatever.
...
To put it a bit more seriously... for a spiritual body like Youyou, it's very simple to enter the Spirit Realm. But for a living person like Yila to go, they need a certificate and coordinates.
It sounds mysterious, but really it's just... having Youyou and Yila stand in the center of the array simultaneously, then quietly waiting for the teleportation to occur. This is one of the charms of the array.
