She didn't mind sharing information about energy crystal with Saohuang because she needed his information as well. She needed to give in order to take. However, the trade wasn't in her favor because it turned out Saohuang knew less than she thought.
He said directly, "I don't have many questions; I'm just curious why you two approached Xia Meng. If there is indeed a motive, I'm pretty sure our target is the same. That thing is very special, but I have no idea what its real usage is, maybe you know."
"What thing?" Xinghe asked.
Saohuang looked at her and laughed. "Are you really that dumb or do you think I'm that dumb?"
"I can't control what you think."
"Xia Xinghe, I've already lost to you, won't you tell me the truth as charity?"
Xinghe stared at him and said, "If you want the truth then you have to trade with truths."
Saohuang groaned helplessly, "I've given you everything I know about this thing that I am talking about."
