It had been a while since Lu Zhou step foot into his office at the Princeton Institute for Advanced Study.
Vera could still contact him through email a few days ago, but now Lu Zhou didn't even reply to her anymore.
Professor Pierre Deligne, who once served as a tutor for Professor Lu, said that this kind of closed-door research where one was completely isolated from the outside world was a unique way for Professor Lu to think. Not replying to emails meant that Lu Zhou was getting closer to the solution…
However, as Lu Zhou's assistant and student, Vera was worried.
Actually, it wasn't only Vera that was worried; Qin Yue and all of the students were also worried about what happened to him.
Therefore, Hardy proposed for the group to take some time out on the weekends to visit Professor Lu.
At the very least, they could confirm whether their professor was still alive…
