"What? You haven't left yet?" Davis chuckled.

His amused voice caused Katherine Hilltail to come out of her reverie.

"Ma-master, did you cure me?"

Davis's expression became confused, "Why would you think that?"

"That… that's because… there is no way I could've regained my blood vitality in such a short amount of time or have my tailbone reconstructed, allowing me to control over my tail!"

Katherine Hilltail screamed out as tears ran down her face. 

"What? Your tailbone is healed!? Your blood essence has rejuvenated? Looks like I have gained an immense benefit by purchasing you. The heavens have blessed me!"

"Wha-"Katherine Hilltail saw Davis stand up and act dumb that anger surged in her crying eyes, "Master, I know it's you. You asked me if my tail was not crippled, would I be able to make a better decision? I still remember those kind words. It cannot be a mistake! You are the one who healed me!"
