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.
