158 "Dire Danger"

Once Ainsley asked, Cellino didn't dare to ignore her, afraid that the baby would fear him. The cat immediately replied right away. 

[Master, creatures like us, sacred beasts, are sensitive to souls. I sense that your soul isn't ordinary, and it's not like any other souls I have seen.] 

Cellino put on a solemn expression even though his cute face wouldn't do much to make him appear more serious. 

[Because I sense your unique soul, I conclude that you're probably not someone from this dimension. It means that you're from another world!] 

Even fantasy creatures in this world still had the same soul aura, but Ainsley's soul felt different. No wonder Cellino immediately thought that she's not from this world. 

Soul aura was naturally the natural-born thing that every creature had in their soul. It was akin to an identity card. 

Every soul would be different, but their aura would remain the same as long as they're from the same dimension.
