"Can Daddy come back soon?" Mu Ai tugged on my sleeve and asked hopefully.
I nodded. "Mm, he'll be back soon."
That was what I told her, but I felt uneasy.
I could sense the powerful yin energy preserved in the express delivery receipts. It didn't leak out, as if it were sealed inside the outer layer of the receipts.
Only when I removed that outer layer was the yin energy exposed. It gathered without dispersing, almost tangible.
The Express Delivery Ghost's yin energy wasn't nearly as powerful. It was as if she had deliberately divided her yin energy, placing its most essential part into these receipts.
