Right now, this world line belongs to Da Vinci's future.
So.
When others ask questions about the future, Einstein would inevitably refuse, but if Da Vinci were to ask, Einstein could spill everything without omission.
What Savior Corporation, mechanical androids, role models leading the way, personal scoring systems... would directly expose her privacy and plans without reservation.
What comes next after exposure?
Clearly.
It inevitably leads to a life-threatening risk.
"Hehe."
Da Vinci slightly smiled:
"I understand what you're worried about, Rhein, you really are a kind person."
"Rest assured, I've attended club meetings for decades, and I have many techniques on how to ask questions and how to restrain Einstein's answers."
Lin Xian nodded, stood up, and prepared to leave the venue:
"Well then, good luck, Miss Da Vinci."
Da Vinci also stood up and followed:
"Same to you, Rhein. But... may I be a bit greedy?"
