"Do you know what that black sludge is?"
"I don't know."
"You don't know? Can't you use your heel to think? Look at you acting all capable."
"..."
Yu Ziqing was at a loss for words and quickly cupped his hands in respect.
"Please enlighten me, I am uneducated. You, sir, are magnanimous, please don't stoop to my level."
Yang snorted softly and set down the teacup.
"This thing, I actually know about it, and I've seen it before.
It's called the Mud of the Muddied World.
I just haven't seen the kind you mentioned that can amass into a whole Mud Sea."
Yu Ziqing said nothing, only refilled Yang's tea.
"Do you know why in many places there are ghosts, especially Evil Ghosts or Fierce Ghosts, that easily lose their sanity and why they haven't been completely eradicated?"
Yu Ziqing wanted to say that it was impossible to completely exterminate ghosts, as long as there are people, there will be an endless stream of ghosts.
