This fantasy novel was called "Divine Martial Cultivation." After a sword immortal reincarnated, their realms were Spirit Guidance realm, Spirit Gathering realm, Spiritual Mansion realm, Spirit Transformation realm, Void Prying realm, Void Reversion realm, Void Initiation realm, and Heavenly Dao realm. There was no such thing as the Ten Directions realm. However, I can recommend a fantasy novel called Ten Realm Soul King, which has the concept of the power of ten realms. I hope you like this fairy's recommendation. Muah ~😗
