Since they began their hours-long trek to the passenger-exclusive Skyship and boarded it, Liu Suyin remained entirely silent, eyes closed, and her expression unchanging as an eternal iceberg awaiting its victims. Wei Wuyin picked up a grape that glistened with astral-grade wood and water essence and ate it.
"Venerable Liu Suyin, so this fascinating city is called the City of Endless?" Wei Wuyin decided to break the ice with this conversation topic. He didn't know what she was allowed to say or not, so he started with harmless topics.
Liu Suyin opened her eyes, revealing those emotional orbs of hers that felt slightly uncomfortable to look into despite their gorgeous and enchanting color. "Yes."
"Hm. Who are those beings with star-shaped pupils and irises like the night sky?" Wei Wuyin inquired about the Celestials as if he was ignorant of them. But the look he received from Liu Suyin felt as if she was skeptical of his question.
FINALLY!
We've solved the mystery of what the hell that book is and why the Celestial Eyes couldn't see through it. xD
