click to show/hide spoilersTenCent's inside joke:
I've only watched up to Ep21 so far. But I've been reading on Soompi forum that the Emperor is actually Fan Xian's father.
Since we're actually dealing with a drama where someone in modern time was nearly dying and woke up to become the MC of Joy of Life, I'm gonna go ahead and say that Tencent was implying that everyone has two fathers, a biological one on Earth who we call father, and another one we should call Father. "father" provides us with our daily breads and living necessities, but "Father" saves our arses out of impossible situations... Tencent really means to imply the King is God, while Fan Xian's father is just a person...
