Zev had been the system spirit of many hosts before Ainsley.
All his hosts were transmigrators, just not all of them came from the earth, the same world as the Godfather and Ainsley's worlds.
However, all this time, he never saw any of the original souls whose bodies were occupied by the hosts come back to demand their bodies.
After all, once someone else occupied their bodies, it meant that they had already passed away. That's how the hosts could occupy another body!
But it also means that the hosts had passed away before they transmigrated into a new body.
When Ainsley heard Zev's explanation, her heart stopped beating for a second.
'So...my original body is already empty? I'm already dead?? B-but I was just using the transmigration magic scroll...how did I die??'
It's not that Ainsley didn't think she would die, but it was just too illogical. How could her natural body die after using that scroll?
