Space-Time Particle.
This was the bait Lin Xian had to throw, under duress, to Copernicus.
Nowadays.
Various countries have already developed mature Hibernation Pod prototypes, which will soon hit the market, and humanity will truly enter the era of hibernation.

Unknown name,
Unknown identity,
Unknown nationality,
Unknown location.
On the vast Earth, trying to find a person without even the slightest clue is like looking for a needle in a haystack.
If the super Artificial Intelligence VV were to help, it would definitely be a lot easier, greatly increasing the probability of locating Copernicus.
But...
Who would dare to bet on such probabilities?
