C1088 Self-destructing Soul

The Secret Realm of Slaughter was the portal that floated in the starry sky.

Every time it opened, it would fully emerge from the void.

The time it takes for the door to exist is not fixed, but when the door is about to close, omens will appear from within the Secret Realm of Slaughter, so there is no need to worry about being locked within the Secret Realm of Slaughter
