After slightly hiding within the Yunyang Palace for half a day, Wang Lu has largely ascertained the ins and outs of the matter.
To put it simply, around three months ago, the apple in King Yunyang's eyes, his beloved daughter, Princess Yunyue suddenly suffered from an odd disease. She fell into a coma and turned gaunt and weak as the days went by. King Yunyang gathered around famous doctors from all over the place, however, all of them were powerless. Finally, they even resorted to trying anyone or anything that even some itinerant healers were also invited to the palace for the diagnosis of the princess.
