A Jar of Pills

"Seven hundred?" Da Xia could hardly believe her ears as she stared at the kitty with a shocked expression covering her face. 

"En!" 

The kitty hurriedly nodded its head but didn't say anything else while trying to keep a distance from its Master as it tried to disappear in the shadows near the farthest corner of the room from the bed where its Master was currently sitting.

"What kind of special pill was it that you needed to spend seven hundred taels?" Da Xia could not stop herself from asking as she tried her very best to not look at the dumbfounded expressions of her husbands. Of course, hearing the amount of 'seven hundred' had given them quite a shock. 

"Master, actually it is a normal pill to cure exhaustion and mild pain, and it doesn't cost too much. One pill is around twenty silver taels but..." The kitty trailed off as it tried to grab something from the system.
