Disturbances in the mortal world came one after another, forcing him to show his edge again and again.
In getting along with the kind and warm Chinese medicine doctor Xia Wanqing, Lin Fan's heart that had been frozen for three hundred years gradually melted.

Between hiding his clumsiness and manifesting his power, he found his own way in the world.
