Heavenly Realm!

Only within the Heavenly Realm can the Twelve Divine Sword Bodies simultaneously manifest.

Moreover, it would only occur when some disciples of the Immortal Sword Emperor gather together, creating such a phenomenon.

Of course, everything about the Heavenly Realm is unknown to outsiders, except for Ye Han, Ye Xinghe, and a few other powerful beings with secretive and special identities who have descended to this world.
