Let's consider the second question.
This question is more targeted.
If Einstein answers that the Space-Time Particle would still be stolen, one could almost certainly deduce that Copernicus must have a backup plan and would continue to steal his own Entangled State of Time-Space Particle, creating more trouble.
If Einstein answers that the Space-Time Particle won't be stolen, it indeed would be somewhat reassuring. But the price is... every member of the Genius Club would know that he's obtained a Space-Time Particle, undoubtedly painting a rather unsafe target on himself.
Newton and Galileo don't look like simple characters; it's possible that once involved, they could be even more troublesome than Copernicus.
"This question is good, but it's too risky."
Lin Xian shakes his head, feeling that Copernicus doesn't have such great clout to justify him taking the risk of exposing his identity and attracting enemies, simply to ascertain Copernicus's wellbeing.
