Regarding the relationship between Liu Jin and Ning Kuan, Ye Wutian could somewhat guess what it was about, but based solely on their private relations, Liu Jin wouldn't likely have invited Ning Kuan to such a grand banquet.
"Ning Kuan?" Liu Yiyi looked puzzled. She only knew that Ning Kuan was one of the Alchemy Masters of the Huaxia Empire, but she had never seen the person before, so she couldn't recognize him earlier.
"The old man with white hair who was walking with your grand uncle just now," Ye Wutian pointed out.
"So that was Ning Kuan?" Liu Yiyi suddenly realized and then guessed, "He, like Liu Jin, is an Alchemy Master, probably invited by him."
