"It seems I screwed up a bit," Conjurer muttered, staring at his body that had become a System Host. But, before the System could fully spread through his body, he snapped his finger, causing his conjured body to explode.
Ding!
The System hovered in the air, gradually dying in response without a Host body to rely upon. There was no other body in this marble world, and hence, it had no other option but to await death.
There wasn't a connection to the Astral Network either, so it was pretty helpless, gradually dying in response as its energy was absorbed by the marble world and digested in a matter of seconds.
Only after that did Conjurer arrive at the place with another conjured body, looking around as he noticed minor changes to the place, frowning as he didn't like the changes, "The changes brought by a mere System is too weak."
