Mortal boy. Yes, even until now, some imperial families still didn't fully understand that Lai Mingyan was picked out by the original gods. It didn't matter if the boy was from the mortal realm with mortal parents.
Then again, for families like these, they wouldn't deem anyone to be of actual value as long as the person hailed from the mortal realm. If only Xu Rouguang wasn't capable of destroying their imperial family, the Imperial Tang—among others—wouldn't give him due respect as well. Right now, they didn't think Lai Mingyan would do such a thing, so they were rather confident.
Whether they actually considered that Lai Mingyan's legal parent was Xu Rouguang or not was unknown to Emperor Sky. Perhaps they were looking at their bloodlines? Emperor Sky still narrowed his eyes. How audacious to sound so direct as if this bluntness was bravery.
