Chen Zhao had an idea. Maybe Sienna would know what the foundation gem was.

Chen Zhao gave her a call. "Sienna."

"Chen, do you know how sinful it is to disturb a lady's sleep?"

"I have a bottle of cream which is definitely better than a single night's sleep."

"What do you need?"

"Do you know what's the foundation gem?"

"Foundation gem? Foundation stone?"

"No idea. I heard it from my friend. I can't confirm if I've heard it wrong or if my friend said it wrong."

"I don't know what the foundation gem is, but I know the foundation stone."

"And what's that?"

"It was part of a cruel method in ancient times. People would draw out the magic sources from ten spiritualists and then combine them in a special way, creating a foundation stone."

"What does a foundation stone do?"

"Don't tell me you're trying to make one."

"I don't even know what it is." Chen Zhao rolled his eyes.
