บท 217: Back To School

The second day after Christmas, near San Francisco International Airport.

When Tao Zhexuan dropped Lu Zhou off at the airport, he said, "Have a safe flight."

Lu Zhou pulled his suitcase out of the trunk and said, "Thanks, come to China when you're free."

"For sure!"

The past two days, Lu Zhou had been exchanging mathematics problems with this genius. Even though they had a twenty years gap, they got along unexpectedly well. Tao Zhexuan was the one who offered to send Lu Zhou to the airport and Lu Zhou had swiftly agreed.

It was not boarding time yet, so Lu Zhou waited in the terminal and read a newspaper. It was the Daily Mail.

Suddenly, a headline attracted his attention.

[The mathematics problem that plagued the community for more than a century, the Riemann's conjecture, was proved by Professor Enoch, from the University of Addo Ekiti, Nigeria!]

Lu Zhou: ? ? ?

The f*ck?
