Grandpa Xia couldn't help but laugh and cry at the realization that his eldest granddaughter of his youngest daughter would possess a great talent with formations. Sadly, Yue Xuexia isn't interested in learning formation and is okay with just listening to the side.
He wasn't surprised, as Grandpa Xia already knew that this little girl's hobby is pill refinement instead. Both pill refinement and formation making are professions that need expensive materials and knowledge. This girl is the divine doctor; she wouldn't have much interest in formation as she is more interested in immortal herbs.
