As for Wei Ling being able to switch cultivation paths so quickly, that was my mistake.
According to this book's original setting, when the True Lords of the Mystic Sect switched cultivation paths, they directly fused with mature spirit bodies. They went from the Demon Race's Great Luo Realm to the Mystic Sect's Fifth Realm, and their cultivation techniques were derived by observing the Black Stone Stele before being passed down.
There was also the setting that mature spirit bodies were exceedingly rare in today's Great Universe, almost impossible to encounter. And the forces beyond the domain had coveted this starry sky for countless ages. Having such a thing should make logical sense, right?
This was the outline and setting I recorded, and Wei Ling's demonic cultivation followed this setting.
But when I just went back through the earlier content, I discovered that I didn't know whether I'd gotten carried away while writing before, but the Mystic Sect's five True Lords seemed not to have followed the original setting. Or rather, it wasn't that they completely failed to follow it—it was just that, when describing their past stories, I seemed to have written them as cultivating from the moment they entered the realm.
My fault. Then Wei Ling will follow this setting!
I'm getting old. I've forgotten some of what I wrote before, and I can only rely on the notes and outline I jotted down to remember. Sorry, Big Shots, please bear with me. Wei Ling will follow the setting of direct fusion.
