[Master, what are you thinking about? :3]
Lu Zhou had been sitting there for half an hour without moving.
Xiao Ai began to wonder if its master was still alive.
Lu Zhou looked at the sun rising from the Purple Mountain in the distance. He looked at the morning mist as he spoke.
"… I'm thinking about my past."
Xiao Ai: [(•̀∀•́)?]
"I really miss it."
Lu Zhou couldn't help but sigh emotionally.
Starting with Zhou's conjecture, to proving his first mathematical proposition: the twin prime conjecture, to the proof of Polignac's conjecture, then Goldbach's conjecture, then later the Millennium Prize Problems…
He had solved so many of the world's hardest problems without even knowing it.
But now, he was taking another step forward.
And this step was farther than any step he had taken before.
Even adding up all of the propositions he had solved, including Riemann's hypothesis, wouldn't hold a candle to what he did half an hour ago.
